Mandatory Caution		General Caution Indicates non-specific general cautions, warnings, and dangers.

CAUTION
Do not touch the terminals while power is being supplied. Doing so may occasionally result in minor injury due to electric shock.	4
Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction.	6
Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion may occasionally occur.
Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur.
CAUTION - Risk of Fire and Electric Shock a) This product is UL listed as Open Type Process Control Equipment. It must be mounted in an enclosure that does not allow fire to escape externally. b) More than one disconnect switch may be required to de-energize the equipment before servicing the product. c) Signal inputs are SELV, limited energy. 1 d) Caution: To reduce the risk of fire or electric shock, do not inter-connect the outputs of different Class 2 circuits. 2	7
If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy. The life expectancy of output relays varies considerably with the output load and switching conditions.

1 A SELV circuit is one separated from the power supply with double insulation or reinforced insulation, that does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.
2 A class 2 power supply is one tested and certified by UL as having the current and voltage of the secondary output restricted to specific levels.

CAUTION
Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose screws may occasionally result in fire. *3
Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable, unexpected operation may occasionally result in property damage or accidents.
A malfunction in the Temperature Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Temperature Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.
A semiconductor is used in the output section of long-life relays. If excessive noise or surge is impressed on the output terminals, a short-circuit failure is likely to occur. If the output remains shorted, fire will occur due to overheating of the heater or other cause. Take measures in the overall system to prevent excessive temperature increase and to prevent fire from spreading.
When inserting the body of the Temperature Controller into the case, confirm that the hooks on the top and bottom are securely engaged with the case. If the body of the Temperature Controller is not inserted properly, faulty contact in the terminal section or reduced water resistance may occasionally result in fire or mal-function.

*3 The tightening torque is 0.5 N·m for the E5CN-U and 0.43 to 0.58 N·m for the E5GN. The terminal torque is 0.5 to 0.6 N·m for auxiliary output 2 on the E5GN.

Precautions for Safe Use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the performance and functions of the product. Not doing so may occasionally result in unexpected events. Use the product within the specifications.

1) The product is designed for indoor use only. Do not use the product outdoors or in any of the following locations. Do not use or store the product in any of the following locations.

Places directly subject to heat radiated from heating equipment.
Places subject to splashing liquid or oil atmosphere.
Places subject to direct sunlight.
Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
Places subject to intense temperature change.
Places subject to icing and condensation.
Places subject to vibration and large shocks.

2) Use and store the Digital Temperature Controller within the rated ambient temperature and humidity.

Gang-mounting two or more temperature controllers, or mounting temperature controllers above each other may cause heat to build up inside the temperature controllers, which will shorten their service life. In such a case, use forced cooling by fans or other means of air ventilation to cool down the Digital Temperature Controllers.

3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on the product.
4) Be sure to wire properly with correct polarity of terminals.
5) Use the specified size of crimp terminals for the E5CN, E5AN, or E5EN (M3.5, width of 7.2 mm or less). For open-wired connections to the E5CN, E5AN, or E5EN, use stranded or solid copper wires with a gauge of AWG24 to AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm²). (The stripping length is 5 to 6 mm.) Up to two wires of the same size and type or two crimp terminals can be connected to one terminal. Do not connect more than two wires or more than two crimp terminals to the same terminal.

Use the specified size of crimp terminals for the E5GN (M3.0, width of 5.8 mm or less). For open-wired connections to the E5GN, use stranded or solid copper wires with a gauge of AWG24 to AWG18 (equal to a cross-sectional area of 0.205 to 0.8231 mm²). (The stripping length for screw terminals is 6 to 8 mm. The stripping length for screwless clamp terminals is 10 mm. The stripping length for auxiliary output 2 is 6 mm.) Up to two wires of the same size and type or two crimp terminals can be connected to one terminal. Do not connect more than two wires or more than two crimp terminals to the same terminal.

Ferrules for screwless clamp terminals must be 0.8 to 1.4mm in diameter and the exposed conductor must be 8 to 12mm in length. Ferrules for auxiliary output 2 must be 0.8 to 1.4mm in diameter and the exposed conductor must be 6mm in length.

6) Do not wire the terminals which are not used.
7) To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block away from power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel to Digital Temperature Controller wiring. Using shielded cables and using separate conduits or ducts is recommended.

When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the temperature controller.

Allow as much space as possible between the Digital Temperature Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

8) Use this product within the rated load and power supply.
9) Make sure that the rated voltage is attained within two seconds of turning ON the power using a switch or relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur.

10) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display.
11) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Digital Temperature Controller. If power is turned ON for the Digital Temperature Controller before turning ON power for the load, self-tuning will not be performed properly and optimum control will not be achieved.
12) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be within easy reach of the operator, and must be marked as a disconnecting means for this unit.
13) Always turn OFF the power supply before removing the body of the E5CN, E5AN, or E5EN from the case, and never touch nor apply shock to the terminals or electronic components. When inserting the interior of the product, do not allow the electronic components to touch the case.
Always turn OFF the power supply before removing the terminal block from the E5GN, and never touch nor apply shock to the terminals or electronic components.
14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
15) Design system (control panel, etc.) considering the 2 second of delay that the controller's output to be set after power ON.
16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing control.
17) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently overwriting data during communications or other operations.
18) Always touch a grounded piece of metal before touching the Digital Temperature Controller to discharge static electricity from your body.
19) Do not remove the terminal block from the E5CN, E5AN, or E5EN. Doing so may result in failure or malfunction.
20) Control outputs that are voltage outputs are not isolated from the internal circuits. When using a grounded thermocouple, do not connect any of the control output terminals to ground. (Doing so may result in an unwanted circuit path, causing error in the measured temperature.)
21) When replacing the body of the E5CN, E5AN, or E5EN, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the E5CN, E5AN, or E5EN to increase, possibly resulting in fire. If the terminals are corroded, replace the case as well.
When removing the terminal block of the E5GN to replace the Digital Temperature Controller, check the condition of the terminals. If corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the terminal block as well.
22) Use suitable tools when taking the Digital Temperature Controller apart for disposal. Sharp parts inside the Digital Temperature Controller may cause injury.
23) When applying Lloyd's standards, install the Digital Temperature Controller according to the requirements given in Shipping Standards.
24) Do not use the Temperature Controller if the front sheet is peeling off or torn.

Service Life

Use the Temperature Controller within the following temperature and humidity ranges:

Temperature: -10 to 55^ (with no icing or condensation), Humidity: 25% to 85%

If the Controller is installed inside a control board, the ambient temperature must be kept to under 55^ , including the temperature around the Controller.

The service life of electronic devices like Temperature Controllers is determined not only by the number of times the relay is switched but also by the service life of internal electronic components. Component service life is affected by the ambient temperature: the higher the temperature, the shorter the service life and, the lower the temperature, the longer the service life. Therefore, the service life can be extended by lowering the temperature of the Temperature Controller.

When two or more Temperature Controllers are mounted horizontally close to each other or vertically next to one another, the internal temperature will increase due to heat radiated by the Temperature Controllers and the service life will decrease. In such a case, use forced cooling by fans or other means of air ventilation to cool down the Temperature Controllers. When providing forced cooling, however, be careful not to cool down the terminals sections alone to avoid measurement errors.

- Ambient Noise

To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block wiring away from power cables carrying high voltages or large currents. Also, do not wire power lines together with or parallel to Digital Temperature Controller wiring. Using shielded cables and using separate conduits or ducts is recommended.

Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils or other equipment that have an inductance component). When a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as close as possible to the Temperature Controller.

Allow as much space as possible between the Digital Temperature Controller and devices that generate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.

- Ensuring Measurement Accuracy

When extending or connecting the thermocouple lead wire, be sure to use compensating wires that match the thermocouple types.

When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use wires that have low resistance and keep the resistance of the three lead wires the same.

Mount the Temperature Controller so that it is horizontally level.

If the measurement accuracy is low, check to see if input shift has been set correctly.

Waterproofing

The degree of protection is as shown below. Sections without any specification on their degree of protection or those with IP 0 are not waterproof.

Front panel: IP66

Rear case: IP20, Terminal section: IP00

(E5CN-U: Front panel: IP50, rear case: IP20, terminals: IP00)

Precautions for Operation

1) It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON. Due consideration must be given to this time when incorporating Temperature Controllers into a control panel or similar device.
2) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the power before starting actual control operations to ensure the correct temperature display.
3) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Temperature Controller. If power is turned ON for the Temperature Controller before turning ON power for the load, self-tuning will not be performed properly and optimum control will not be achieved. When starting operation after the Temperature Controller has warmed up, turn OFF the power and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.)
4) Avoid using the Controller in places near a radio, television set, or wireless installing. The Controller may cause radio disturbance for these devices.

Shipping Standards

The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with Lloyd's standards. When applying the standards, the following installation and wiring requirements must be met in the application.

■ Application Conditions

1) Installation Location

The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with installation category ENV1 and ENV2 of Lloyd's standards. Therefore, they must be installed in a location equipped with air conditioning. They must therefore be installed in a location equipped with air conditioning. They cannot be used on the bridge or decks, or in a location subject to strong vibration.

2) Wiring Conditions

Upgraded Functions

The functionality of the E5CN, E5CN-U, E5AN, and E5EN was improved starting from December 2007 production.

The functionality of the E5GN was improved starting from August 2009 production.

The design of the front panel can be used to differentiate between the previous and upgraded models.

E5CN/CN-U

The upgraded Controllers are basically compatible with the previous Controllers. Terminal arrangements, terminal sizes, and panel mounting depth have not been changed.

E5AN/EN

Although the upgraded Controllers are compatible with the previous Controllers, terminal arrangements have been changed. Terminal sizes and panel mounting depth have not been changed.

E5GN

Model numbers have changed accompanying the introduction of universal input capability. The default setting of the input type parameter of the E5GN-□□□P (models with resistance thermometers) has been changed from a Pt100 resistance thermometer to a K thermocouple. Make sure the setting of the input type parameter agrees with the temperature sensor that is being used.

The terminal block has also been changed, which means the wiring methods and terminal arrangement are different.

Other changes outlined in the following tables. Refer to relevant pages in the manual for details.

Model Notation

The E5CN-□□□, E5CN-□□□U, E5AN-□□□, E5EN-□□□, and E5GN-□□□ are given as the E5CN, E5CN-U, E5AN, E5EN, and E5GN when they share functionality.

The following notation is used when specifying differences in functionality.

Notation	Options
E5☐N-☐☐B	Two event inputs
E5☐N-☐☐03	RS-485 communications
E5☐N-☐☐H	One of HB, HS, and heater overcurrent detection
E5☐N-☐☐HH	Two of HB, HS, and heater overcurrent detection (See note 1.)
E5☐N☐Q	Control output 2 (voltage output) (See note 1.)
E5☐N-☐☐P	External power supply to ES1B (See note 1.)
E5☐N-☐☐01	RS-232C communications (See note 2.)
E5☐N-☐☐F	Transfer output (See note 3.)

Note: (1) Excluding the E5GN.

(2) Excluding the E5CN.

(3) The E5AN and E5EN only.

Meanings of Abbreviations

The following abbreviations are used in parameter names, figures and in text explanations. These abbreviations mean the following:

Symbol	Term
PV	Process value
SP	Set point
SV	Set value
AT	Auto-tuning
ST	Self-tuning
HB	Heater burnout
HS	Heater short (See note 1.)
OC	Heater overcurrent
LBA	Loop burnout alarm
EU	Engineering unit (See note 2.)

Note: (1) A heater short indicates that the heater remains ON even when the control output from the Temperature Controller is OFF because the SSR has failed or for any other reason.

(2) "EU" stands for Engineering Unit. EU is used as the minimum unit for engineering units such as ^ C , m, and g. The size of EU varies according to the input type.

For example, when the input temperature setting range is -200 to +1300^ , 1 EU is 1^ , and when the input temperature setting range is -20.0 to +500.0^ , 1 EU is 0.1^ .

For analog inputs, the size of EU varies according to the decimal point position of the scaling setting, and 1 EU becomes the minimum scaling unit.

The display is determined by the currently set value of the Temperature Unit parameter. °F indicates °C and °F indicates °F. This indicator flashes during ST operation. It is OFF on models with linear inputs.

1-1-3 Using the Keys

PF (Function (Auto/ Manual)) Key (E5AN/EN Only)

This section describes the basic functions of the front panel keys.

This is a function key. When it is pressed for at least 1 second, the function set in the PF Setting parameter will operate.

Example: When A-M (auto/manual) is selected in the PF Setting parameter (initial value: A-M), the key operates as an auto/manual switch, switching between Auto Mode and Manual Mode. If the key is pressed for more than 1 second (regardless of key release timing), the mode will switch.

Key

Press this key to move between setting levels. The setting level is selected in the following order: operation level: adjustment level, initial setting level, communications setting level.

Key

Press this key to change parameters within a setting level.

The parameters can be reversed by holding down the key (moving one per second in reverse order).

Key

Each press of this key increments the value displayed on the No. 2 display or advances the setting. Holding the key down speeds up the incrementation.

Key

Each press of this key decrements values displayed on the No. 2 display or reverses the setting. Holding the key down speeds up the incrementation.

Keys

Press these keys to change to the protect level. For details on operations involving holding these keys down simultaneously, refer to 1-3 Setting Level Configuration and Key Operations. For details on the protect level, refer to SECTION 5 Parameters.

1-2-2 Main Functions

This section introduces the main E5CN/CN-U/AN/EN/GN functions. For details on particular functions and how to use them, refer to SECTION 3 Basic Operation and following sections.

Input Sensor Types

The following input sensors can be connected for temperature input (i.e., E5_N-□□□□T):

Thermocouple: K, J, T, E, L, U, N, R, S, B, W, PLII Infrared temperature sensor: ES1B

10 to 70^ , 60 to 120^ , 115 to 165^ , 140 to 260^

Platinum resistance thermometer: Pt100, JPt100

Analog input: 0 to 50mV

Control Outputs

Inputs with the following specifications can be connected for analog input (i.e., E5_N-□□□□L):

Current input: 4 to 20mA DC, 0 to 20mA DC

Voltage input: 1 to 5 VDC, 0 to 5 V DC, 0 to 10 V DC

A control output can be a relay, voltage (for driving SSR), or current output, depending on the model.
Long-life relay outputs (see note) use semiconductors for switching when closing and opening the circuit, thereby reducing chattering and arcing and improving durability. However, if high levels of noise or surge are imposed between the output terminals, short-circuit faults may occasionally occur. If the output becomes permanently shorted, there is the danger of fire due to overheating of the heater. Design safety into the system, including measures to prevent excessive temperature rise and spreading of fire. Take countermeasures such as installing a surge absorber. As an additional safety measure, provide error detection in the control loop. (Use the Loop Burnout Alarm (LBA) and HS alarm that are provided for the E5□N.)

OMRON E5EN - Control Outputs - 1

Select a surge absorber that satisfies the following conditions.

Voltage used	Varistor voltage	Surge resistance
100 to 120 VAC	240 to 270 V	1,000 A min.
200 to 240 VAC	440 to 470 V	1,000 A min.

Always connect an AC load to a long-life relay output (see note). The output will not turn OFF if a DC load is connected.

Note Long-life relay outputs are not supported for the E5GN.

Alarms

Set the alarm type and alarm value or the alarm value upper and lower limits.
If necessary, a more comprehensive alarm function can be achieved by setting a standby sequence, alarm hysteresis, auxiliary output close in alarm/open in alarm, alarm latch, alarm ON delay, and alarm OFF delay.
If the Input Error Output parameter is set to ON, the output assigned to alarm 1 function will turn ON when an input error occurs.

Control Adjustment

Optimum PID constants can be set easily by performing AT (auto-tuning) or ST (self-tuning).

Event Inputs

With the E53-CN□B□N2 for the E5CN or the E5AN/EN-□M□-500-N with the E53-AKB for the E5AN/EN, the following functions can be executed using event inputs: switching set points (multi-SP, 4 points max.), switching RUN/STOP, switching between automatic and manual operation, starting/resetting the program, inverting direct/reverse operation, 100% AT execute/cancel, 40% AT execute/cancel, setting change enable/disable, and canceling the alarm latch.

Heater Burnout, HS Alarm, and Heater Overcurrent

With the E53-CN□H□N2 or E53-CN□HH□N2 for the E5CN, or the E5AN/EN-□□H□-500-N or E5AN/EN-□□HH□-500-N, the heater burnout detection function, HS alarm function, and heater overcurrent detection function can be used.

Communications Functions	● Communications functions utilizing CompoWay/F (See note 1.), SYSWAY (See note 2.), or Modbus (See note 3.) can be used. RS-485 Interface Use the E53-CN□03N2 for the E5CN or the E53-EN03 for the E5AN/EN. RS-232C Interface Use the E53-EN01 for the E5AN/EN.
Note	(1) CompoWay/F is an integrated general-purpose serial communications protocol developed by OMRON. It uses commands compliant with the well-established FINS, together with a consistent frame format on OMRON Programmable Controllers to facilitate communications between personal computers and components. (2) SYSWAY communications do not support alarm 3. (3) Modbus is a communications control method conforming to the RTU Mode of Modbus Protocol. Modbus is a registered trademark of Schneider Electric. (4) The E5CN and E5CN-U do not support the RS-232C interface.
External Power Supply for ES1B	The E5AN-□P□-N or E5EN-□P□-N with the E53-CN□P□N2 can be used as the power supply for ES1B Infrared Temperature Sensors.
Note	The E5GN does not provide a power supply for an ES1B Infrared Temperature Sensor.
Transfer Output	A transfer output for 4 to 20 mA can be used with the E5AN/E5EN-□□F. For E5□N-C□□ models (models without “F” in the model number), the current output can be used as a simple transfer output.

1-3 Setting Level Configuration and Key Operations

Parameters are divided into groups, each called a level. Each of the set values (setting items) in these levels is called a parameter. The parameters on the E5CN/CN-U/AN/EN/GN are divided into the following 9 levels.

When the power is turned ON, all of the display lights for approximately one second.

OMRON E5EN - 1-3 Setting Level Configuration and Key Operations - 1

Note

(1) You can return to the operation level by executing a software reset.
(2) You cannot move to other levels by operating the keys on the front panel from the calibration level. You must turn OFF the power supply.
(3) From the manual control level, key operations can be used to move to the operation level only.

Level	Control in progress	Control stopped
Protect level	Can be set.	---
Operation level	Can be set.	---
Adjustment level	Can be set.	---
Manual control level	Can be set.	---
Monitor/setting item level	Can be set.	---
Initial setting level	---	Can be set.
Advanced function setting level	---	Can be set.
Calibration level	---	Can be set.
Communications setting level	---	Can be set.

Of these levels, the initial setting level, communications setting level, advanced function setting level, and calibration level can be used only when control is stopped. Control outputs are stopped when any of these four levels is selected.

(4) When the PF Setting is set to A-M in models with a PF Key (E5AN/EN)
(5) When the PF Setting is set to PFDP in models with a PF Key (E5AN/EN)

Protect Level

To switch to the protect level from the operation level, the adjustment level, or the monitor/setting item level, simultaneously hold down the and Keys for at least 3 seconds. (See note.) This level is for preventing unwanted or accidental modification of parameters. Protected levels will not be displayed, and so the parameters in that level cannot be modified.

Note The key pressing time can be changed in Move to Protect Level parameter (advanced function setting level).

Operation Level

The operation level is displayed when the power is turned ON. You can move to the protect level, initial setting level, or adjustment level from this level.
Normally, select this level during operation. While operation is in progress, items such as the PV and manipulated variable (MV) can be monitored, and the set points, alarm values, and alarm upper and lower limits can be monitored and changed.

Adjustment Level

To move to the adjustment level, press the Key once (for less than 1 s).
This level is for entering set values and offset values for control. In addition to AT (auto-tuning), communications write enable/disable switching, hysteresis settings, multi-SP settings, and input offset parameters, it includes HB alarm, HS alarm, OC alarm, and PID constants. From the adjustment level, it is possible to move to the top parameter of the initial setting level, protect level, or operation level.

Monitor/Setting Item Level

To switch to the monitor/setting item level, press the PF Key from the operation level or adjustment level. The contents set for monitor/setting items 1 to 5 can be displayed. You can move from the monitor/setting item level to the operation level or initial setting level. (This level is supported by the E5AN and E5EN only.)

Manual Control Level

When the Key is pressed for at least 3 seconds from the operation level's auto/manual switching display, the manual control level will be displayed. (The MANU indicator will light.)
When the PF Setting is set to A-M (auto/manual) and the PF Key is pressed for more than one second from the operation level or adjustment level, the manual control level will be displayed (E5AN and E5EN only.)
This is the level for changing the MV in manual mode.
To return to the operation level, press the Key for at least one second. It is also possible to return to the operation level by pressing the PF Key for more than one second when the PF Setting is set to A-M.

Initial Setting Level

To move to the initial setting level from the operation level or the adjustment level, press the Key for at least 3 seconds. The PV display flashes after one second. This level is for specifying the input type and selecting the control method, control period, setting direct/reverse operation, setting the alarm types, etc. You can move to the advanced function setting level or communications setting level from this level. To return to the operation level, press the Key for at least one second. To move to the communications setting level, press the Key for less than one second.

(When moving from the initial setting level to the operation level, all the indicators will light.)

Note Pressing the Key for at least 3 seconds in the operation level's auto/manual switching display will move to the manual control level, and not the initial setting level.

Advanced Function Setting Level

To move to the advanced function setting level, set the Initial Setting/Communications Protect parameter in the protect level to 0 and then, in the initial setting level, input the password (-169).
From the advanced function setting level, it is possible to move to the calibration level or to the initial setting level.
This level is for setting the automatic display return time and standby sequence, and it is the level for moving to the user calibration and other functions.

Communications Setting Level

To move to the communications setting level from the initial setting level, press the Key once (for less than 1 s). When using the communications function, set the communications conditions in this level. Communicating with a personal computer (host computer) allows set points to be read and written, and manipulated variables (MV) to be monitored.

Calibration Level

To move to the calibration level, input the password (1201) from the advanced function setting level. The calibration level is for offsetting error in the input circuit.
You cannot move to other levels from the calibration level by operating the keys on the front panel. To cancel this level, turn the power OFF then back ON again.

1-3-1 Selecting Parameters

Within each level, the parameter is changed in order (or in reverse order) each time the l Key is pressed. (In the calibration level, however, parameters cannot be changed in reverse order.) For details, refer to SECTION 5 Parameters.

OMRON E5EN - 1-3-1 Selecting Parameters - 1

1-3-2 Saving Settings

If you press the Key at the final parameter, the display returns to the top parameter for the current level.
To change parameter settings, specify the setting using the or Key, and either leave the setting for at least two seconds or press the Key. This saves the setting.
When another level is selected after a setting has been changed, the contents of the parameter prior to the change is saved.
When you turn the power OFF, you must first save the settings (by pressing the Key). The settings are sometimes not changed by merely pressing the or Keys.

1-4 Communications Function

The E5CN/AN/EN/GN are provided with a communications function that enables parameters to be checked and set from a host computer. If the communications function is required, use the E53-CN□03N2 with the E5CN, or the E53-EN03 or E53-EN01 with the E5AN/EN/GN. For details on the communications function, see the separate Communications Manual Basic Type. Use the following procedure to move to the communications setting level.

1,2,3... 1. Press the Key for at least three seconds to move from the operation level to the initial setting level.
2. Press the Key for less than one second to move from the initial setting level to the communications setting level.
3. Select the parameters as shown below by pressing the Key.
4. Press the or Key to change the parameter setting.

OMRON E5EN - 1-4 Communications Function - 1

Note The Protocol Setting parameter is displayed only when CompoWay/F communications are being used.

Setting Communications Data

Match the communications specifications of the E5CN/AN/EN/GN and the host computer. If a 1:N connection is being used, ensure that the communications specifications for all devices in the system (except the communications Unit No.) are the same.

2-2-3 Wiring

Power supply

In the connection diagrams, the left side of the terminal numbers represents the inside of the Controller and the right side represents the outside.

With the E5CN, connect to terminals 9 and 10; with the E5CN-U, connect to pins 10 and 11; with the E5AN, E5EN, and E5GN, connect pins 1 and 2. The following table shows the specifications.

Input power supply	E5CN	E5CN-U	E5AN/EN	E5GN
100 to 240 VAC, 50/60 Hz	7.5 VA	6 VA	10 VA	5.5 VA
24 VAC, 50/60 Hz	5 VA	3 VA	5.5 VA	3 VA
24 VDC (no polarity)	3 W	2 W	4 W	2 W

These models have reinforced insulation between the input power supply, the relay outputs, and other terminals.

Input

Make the connections according to the input type as shown below, using terminals 3 to 5 for the E5CN, pins 1 to 3 for the E5CN-U, pins 18 to 20 for the E5AN or E5EN and pins 10 to 12 for the E5GN.

When extending the thermocouple lead wires, be sure to use compensating wires that match the thermocouple type. When extending the lead wires of a platinum resistance thermometer, be sure to use wires that have low resistance and keep the resistance of the three lead wires the same.

Control Output 1

Outputs are sent from terminals 1 and 2 with the E5CN, from pins 4 to 6 with the E5CN-U, and from pins 3 and 4 with the E5AN/EN/GN. The following diagrams show the available outputs and their internal equalizing circuits.

OMRON E5EN - Control Output 1 - 1

The following table shows the specifications for each output type.

E5CN/CN-U

Relay	250 VAC, 3 A (resistive load), electrical durability: 100,000 operations
Long-life relay (using a triac)	250 VAC, 3 A (resistive load), electrical durability: 1,000,000 operations
Voltage (for driving SSR)	PNP type, 12 VDC ±15%, 21 mA (with short-circuit protection)
Current	DC 4 to 20 mA/DC 0 to 20 mA, resistive load: 600 Ω max. Resolution: Approx. 10,000

E5AN/EN

Output type	Specifications
Relay	250 VAC, 5 A (resistive load), electrical durability: 100,000 operations
Voltage (for driving SSR)	PNP type, 12 VDC +15%, 40 mA (with short-circuit protection)
Current	DC 4 to 20 mA/DC 0 to 20 mA, resistive load: 600 Ω max. Resolution: Approx. 10,000

E5GN

Output type	Specifications
Relay	250 VAC, 2 A (resistive load), electrical durability: 100,000 operations
Voltage (for driving SSR)	PNP type, 12 VDC ±15%, 21 mA (with short-circuit protection)
Current	DC 4 to 20 mA/DC 0 to 20 mA, resistive load: 500 Ω max. Resolution: Approx. 10,000

Always connect an AC load to a long-life relay output. The output will not turn OFF if a DC load is connected.
The voltage output (for driving SSR) is not electrically isolated from the internal circuits. When using a grounding thermocouple, do not connect any of the control output terminals to the ground. If a control output terminal is connected to the ground, errors will occur in the measured temperature as a result of leakage current.
Control output 1 (voltage output for driving SSR) and control output 2 (voltage output for driving SSR) are not isolated. For the E5AN/EN, however, the internal circuits are functionally isolated.
Long-life relay outputs use semiconductors for switching when closing and opening the circuit, thereby reducing chattering and arcing and improving durability. However, if high levels of noise or surge are imposed between the output terminals, short-circuit faults may occasionally occur. If the output becomes permanently shorted, there is the danger of fire due to overheating of the heater. Design safety into the system, including measures to prevent excessive temperature rise and spreading of fire.
Take countermeasures such as installing a surge absorber. As an additional safety measure, provide error detection in the control loop. (Use the Loop Burnout Alarm (LBA) and HS alarm that are provided for the E5☐N.)

OMRON E5EN - Control Output 1 - 2

Select a surge absorber that satisfies the following conditions.

100 to 120 VAC	240 to 270 V	1,000 A min.
200 to 240 VAC	440 to 470 V	1,000 A min.

Control Output 2

Outputs are sent from terminals 11, 12, 14, and 15 with the E5CN, and from pins 14 and 15 with the E5AN/EN. The following diagrams show the available outputs and their internal equalizing circuits.

OMRON E5EN - Control Output 2 - 1

Always connect an AC load to a long-life relay output. The output will not turn OFF if a DC load is connected.
The voltage output (for driving SSR) is not electrically isolated from the internal circuits. Therefore, when using a grounding thermocouple, do not connect any of the control output terminals to the ground. If a control output terminal is connected to the ground, errors will occur in the measured temperature as a result of leakage current. With E5AN/EN, however, control output 2 (voltage output for driving SSR) is functionally isolated from the internal circuits.
Control output 2 of the E5CN is a voltage output (for driving SSR) only, and outputs across terminals 11(+) and 12(-) , or 14(+) and 15(-) .
Control output 1 (voltage output for driving SSR) and control output 2 (voltage output for driving SSR) are not isolated.
Long-life relay outputs use semiconductors for switching when closing and opening the circuit, thereby reducing chattering and arcing and improving durability. However, if high levels of noise or surge are imposed between the output terminals, short-circuit faults may occasionally occur. If the output becomes permanently shorted, there is the danger of fire due to overheating of the heater.

When the Input Error Output parameter is set to ON, the output assigned to the alarm 1 function turns ON when an input error occurs.
When the HB alarm, HS alarm, or heater overcurrent alarm is used with the E5CN-□□H□, E5CN-□□HH□, or E5GN-□□H□, alarms are output to the output assigned to the alarm 1 function.
When the HB alarm, HS alarm, or heater overcurrent alarm is used with the E5AN/EN-□□H□□, alarms are output to the output assigned to the alarm 1 function.
On the E5CN and E5CN-U, when heating/cooling control is used, auxiliary output 2 becomes control output (cooling).
On the E5AN and E5EN, when heating/cooling control is used, auxiliary output 3 becomes control output (cooling).
On the E5GN, when heating/cooling control is used, auxiliary output 1 becomes control output (cooling).
For models that have a heater burnout alarm, an OR of the alarm 1 function and the HB alarm, HS alarm, or heater overcurrent alarm is sent to the output assigned to the alarm 1 function (auxiliary output 1). If the alarm 1 function is to be used for HB alarm only, set the alarm 1 type to 0 (i.e., do not use alarm 1 function).

To return to the operation level, press the Key for at least one second.

3-4 Selecting PID Control or ON/OFF Control

Two control methods are supported: 2-PID control and ON/OFF control. Switching between 2-PID control and ON/OFF control is executed by means of the PID ON/OFF parameter in the initial setting level. When this parameter is set to L^-d , 2-PID control is selected, and when set to ^N , ON/OFF control, is selected. The default is ^N_ .

2-PID Control

PID control is set by AT (auto-tuning), ST (self-tuning), or manual setting.

For PID control, set the PID constants in the Proportional Band (P), Integral Time (I), and Derivative Time (D) parameters.

ON/OFF Control

In ON/OFF control, the control output is turned ON when the process value is lower than the current set point, and the control output is turned OFF when the process value is higher than the current set point (reverse operation).

3-5 Setting Output Specifications

3-5-1 Control Periods

OMRON E5EN - 3-5-1 Control Periods - 1

Control Period (Heating)

OMRON E5EN - 3-5-1 Control Periods - 2

Control Period (Cooling)

Set the output periods (control periods). Though a shorter period provides better control performance, it is recommended that the control period be set to 20 seconds or longer for a relay output to preserve the service life of the relay. After the settings have been made in the initial setup, readjust the control period, as required, by means such as trial operation.
Set the control periods in the Control Period (Heating) and Control Period (Cooling) parameters in the initial setting level. The default is 20 seconds.
The Control Period (Cooling) parameter is used only for heating/cooling control.
When control output 1 is used as a current output, Control Period (Heating) cannot be used.

3-5-2 Direct and Reverse Operation

Direct operation increases the manipulated variable whenever the process value increases. Reverse operation decreases the manipulated variable whenever the process value increases.

OMRON E5EN - 3-5-2 Direct and Reverse Operation - 1

OMRON E5EN - 3-5-2 Direct and Reverse Operation - 2
Direct operation
Reverse operation

For example, when the process value (PV) is lower than the set point (SP) in a heating control system, the manipulated variable increases according to the difference between the PV and SP. Accordingly, reverse operation is used in a heating control system. Direct operation is used in a cooling control system, in which the operation is the opposite of a heating control system. The Control Output 1 Assignment is set to (control output (heating)) for either direct or reverse operation.

Direct/reverse operation is set in the Direct/Reverse Operation parameter in the initial setting level. The default is ^R - (reverse operation).

Operating Procedure

In this example, the input type, temperature unit, direct/reverse operation, and control period (heat) parameters are checked.

Input type = 5 (K thermocouple)
Temperature unit = (^) Direct/reverse operation = R - R (reverse operation)

Control Output 1 Assignment	aUb1	Control output (heating)
Control Output 2 Assignment	aUb2	Not assigned.
Auxiliary Output 1 Assignment	5Ub1	Alarm 1
Auxiliary Output 2 Assignment	5Ub2	Alarm 2
Auxiliary Output 3 Assignment (E5AN/EN only)	5Ub3	Alarm 3

Refer to pages 240 to 242 for the functions that can be assigned to the outputs.
Each output is automatically initialized as shown below by changing the control mode.

Example: E5CN

Parameter name	Symbol	Without control output 2		With control output 2
Parameter name	Symbol	Standard	Heating/cooling	Standard	Heating/cooling
Control Output 1 Assignment	$ \bar{u} $	Control output (heating)	Control output (heating)	Control output (heating)	Control output (heating)
Control Output 2 Assignment	$ \bar{u} $	Not assigned. (See note 1.)	Not assigned. (See note 1.)	Not assigned.	Control output (cooling)
Auxiliary Output 1 Assignment	$ \bar{S} $	Alarm 1 (See note 2.)	Alarm 1 (See note 2.)	Alarm 1 (See note 2.)	Alarm 1 (See note 2.)
Auxiliary Output 2 Assignment	$ \bar{S} $	Alarm 2 (See note 3.)	Control output (cooling) (See note 3.)	Alarm 2	Alarm 2

Example: E5GN

Parameter name	Symbol	Standard	Heating/cooling
Control Output 1 Assignment	$ \bar{a}U_{\text{ct}} $	Control output (heating)	Control output (heating)
Auxiliary Output 1 Assignment	$ \bar{S}U_{\text{ct}} $	Alarm 1 (See note 2.)	Control output (cooling)
Auxiliary Output 2 Assignment	$ \bar{S}U_{\text{ct}} $	Alarm 2	Alarm 2

Note

(1) There is no control output 2 and no parameter assignment is displayed for that output.
(2) The Auxiliary Output 1 Assignment parameter becomes the program end output unless the Program Pattern parameter is set to OFF.
(3) For the E5AN/EN, the Auxiliary Output 3 Assignment parameter is set as the control output for cooling. (The Auxiliary Output 2 Assignment parameter is set for alarm 2).

Alarms

It will be specified in this section when an alarm must be assigned, i.e., when an alarm must be set for the Control Output 1 or 2 Assignment parameters, or for the Auxiliary Output 1 to 3 Assignment parameters. For example, if alarm 1 is set for the Control Output 1 Assignment parameter, then alarm 1 has been assigned.

Assigning a work bit to either control output 1 or 2 or to auxiliary output 1 to 3 is also considered to be the same as assigning an alarm. For example, if work bit 1 is set for the Auxiliary Output 1 Assignment parameter, then alarms 1 to 3 have been assigned.

Operating Procedure

This procedure sets the following control and auxiliary output assignments.

Control output 1: Control output (heating); Control output 2: Control output (cooling); Auxiliary output 1: Alarm 1; Auxiliary output 2: Alarm 2

In this example, the set point is changed from 0^ to 200^ .

Normally, the Process Value/Set Point parameter is displayed. The set point is 0^ .
Use the and Keys to set the set point to 200^ .

3-7 Using ON/OFF Control

In ON/OFF control, the control output turns OFF when the temperature being controlled reaches the preset set point. When the manipulated variable turns OFF, the temperature begins to fall and the control turns ON again. This operation is repeated over a certain temperature range. At this time, how much the temperature must fall before control turns ON again is determined by the Hysteresis (Heating) parameter. Also, what direction the manipulated variable must be adjusted in response to an increase or decrease in the process value is determined by the Direct/Reverse Operation parameter.

3-7-1 ON/OFF Control

Hysteresis

Switching between 2-PID control and ON/OFF control is performed using the PID ON/OFF parameter in the initial setting level. When this parameter is set to L^-d , 2-PID control is selected, and when it is set to N^-F , ON/OFF control is selected. The default is N_^-F .
With ON/OFF control, hysteresis is used to stabilize operation when switching between ON and OFF. The control output (heating) and control output (cooling) functions are set in the Hysteresis (Heating) and Hysteresis (Cooling) parameters, respectively.
In standard control (heating or cooling control), the setting of the Hysteresis (Heating) parameter in the adjustment level is used as the hysteresis regardless of whether the control type is heating control or cooling control.

OMRON E5EN - Hysteresis - 1

Three-position Control

In heating/cooling control, a dead band (an area where both control outputs are 0) can be set to either the heating or cooling side. This makes it possible to use 3-position control.

3-8 Determining PID Constants (AT, ST, Manual Setup)

3-8-1 AT (Auto-tuning)

OMRON E5EN - 3-8-1 AT (Auto-tuning) - 1

When AT is executed, the optimum PID constants for the set point at that time are set automatically. A method (called the limit cycle method) for forcibly changing the manipulated variable and finding the characteristics of the control object is employed.
Either 40% AT or 100% AT can be selected depending on the width of MV variation in the limit cycle. In the AT Execute/Cancel parameter, specify - (100% AT) or - (40% AT). To cancel AT, specify (AT cancel).
Only 100% AT can be executed for heating and cooling control.
AT cannot be executed when control has stopped or during ON/OFF control.
The results of AT are reflected in the Proportional Band (P), Integral Time (I), and Derivative Time (D) parameters in the adjustment level.

AT is started when either - (100% AT) or - 1 (40% AT) is specified for the AT Execute/Cancel parameter. During execution, the AT Execute/Cancel parameter on the No. 1 display flashes. When AT ends, the AT Execute/Cancel parameter turns OFF, and the No. 1 display stops flashing.

OMRON E5EN - AT Operations - 1

If you move to the operation level during AT execution, the No. 2 display flashes to indicate that AT is being executed.

PV/SP

OMRON E5EN - AT Operations - 2

Only the Communications Writing, RUN/STOP, AT Execution/Cancel, and Program Start parameters can be changed during AT execution. Other parameters cannot be changed.

AT Calculated Gain

The AT Calculated Gain parameter sets the gain for when PID values are calculated using AT. When emphasizing response, decrease the set value. When emphasizing stability, increase the set value.

AT Hysteresis

The AT Hysteresis parameter sets the hysteresis when switching ON and OFF for the limit cycle operation during auto-tuning.

Limit Cycle MV Amplitude

The Limit Cycle MV Amplitude parameter sets the MV amplitude for limit cycle operation during auto-tuning.

Note This setting is disabled for 100% AT.

40% AT

The width of MV variation in the limit cycle can be changed in the Limit Cycle MV Amplitude parameter, but the AT execution time may be longer than for 100% AT. The limit cycle timing varies according to whether the deviation (DV) at the start of auto-tuning execution is less than 10% FS.

3-8-2 ST (Self-tuning)

OMRON E5EN - 3-8-2 ST (Self-tuning) - 1

ST (self-tuning) is a function that finds PID constants by using step response tuning (SRT) when Controller operation begins or when the set point is changed.

Once the PID constants have been calculated, ST is not executed when the next control operation is started as long as the set point remains unchanged.

ST (self-tuning) is enabled when the ST parameter is set to ON in the initial setting level.

When the ST function is in operation, be sure to turn the power supply of the load connected to the control output ON simultaneously with or before starting Controller operation.

When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before supplying power to the Digital Temperature Controller. If power is turned ON for the Digital Temperature Controller before turning ON power for the load, self-tuning will not be performed properly and optimum control will not be achieved.

Note

PID Constants

When control characteristics are already known, PID constants can be set directly to adjust control. PID constants are set in the Proportional Band (P), Integral Time (I), and Derivative Time (D) parameters in the adjustment level.

Startup Conditions

Self-tuning by step response tuning (SRT) is started when the following conditions are met after program execution is started and the set point is changed.

At start of operation

When set point is changed

1. The set point at the start of operation differs from the set point when the previous SRT was executed. (See note 1.)2. The difference between the temperature at the start of operation and the set point is greater both of the following: (Present proportional band × 1.27 + 4°C) and the ST stable range.3. The temperature at the start of operation is lower than the set point during reverse operation, and is larger than the set point during direct operation.4. There is no reset from input errors.

1. The new set point differs from the set point used when the previous SRT was executed. (See note 1.)2. The set point change width is greater both of the following: (Present proportional band × 1.27 + 4°C) and the ST stable range.3. During reverse operation, the new set point is larger than the set point before the change; and during direct operation, the new set point is smaller than the set point before the change.4. The temperature is stable. (See note 2.) (Equilibrium with the output amount at 0% when the power is turned ON is also all right.) (See note 3.)

Note

(1) The previous SRT-implemented set point is the set point that was used for calculating the PID constants for the previous SRT.
(2) In this state, the measurement point is within the ST stable range.
(3) In this state, the change width of the PV every 60 seconds is within the ST stable range or less.

In the following instances, PID constants are not changed by self-tuning (ST) for the present set point.

1,2,3...

When the PID constants have been changed manually with ST set to ON.

3-8-3 RT (Robust Tuning)

OMRON E5EN - 3-8-3 RT (Robust Tuning) - 1

When AT or ST is executed with RT selected, PID constants are automatically set that make it hard for control performance to degenerate even when the characteristics of the controlled object are changed.
RT can be set in the advanced function setting level when PID control has been set.
The RT mode cannot be selected while an analog input is set.
Selecting the RT mode in the following cases will help to prevent hunting from occurring.
When the set temperature is not constant and is changed in a wide range
When there are large variations in ambient temperatures due to factors such as seasonal changes or differences between day and night temperatures
When there are large variations in ambient wind conditions and air flow
When heater characteristics change depending on the temperature
When an actuator with disproportional I/O, such as a phase-control-type power regulator, is used
When a rapidly heating heater is used
When the control object or sensor has much loss time
When hunting occurs in normal mode for any reason
PID constants are initialized to the factory settings by switching to RT mode.
When the RT mode is selected, the derivative time setting unit becomes the second.

RT Features

Even when hunting occurs for PID constants when AT or ST is executed in normal mode, it is less likely to occur when AT or ST is executed in RT mode.

OMRON E5EN - RT Features - 1

When the temperature (PV) falls short of the set point for the PID constants when using AT or ST in normal mode, executing AT or ST in RT mode tends to improve performance.

OMRON E5EN - RT Features - 2

When the manipulated variable (MV) is saturated, the amount of overshooting may be somewhat higher in comparison to PID control based on AT or ST in normal mode.

Decreased	Set value	Overshooting and hunting occur, but the set value is quickly reached and the temperature stabilizes.

When I (Integral Time) Is Adjusted

Increased	Set value	It takes a long time to reach the set point. It takes time to achieve a stable state, but overshooting, undershooting, and hunting are reduced.
Decreased	Set value	Overshooting and undershooting occur. Hunting occurs. The Controller starts up faster.

When D (Derivative Time) Is Adjusted

Increased	Set value	Overshooting, undershooting, and stabilization times are reduced, but fine hunting occurs on changes in the curve itself.
Decreased	Set value	Overshooting and undershooting increase, and it takes time to return to the set point.

3-9 Alarm Outputs

Alarms can be used by the E5CN-□2□□ (2 auxiliary outputs), E5AN/E5EN-□1□□□ (1 auxiliary output), E5AN/E5EN-□3□□□ (3 auxiliary outputs), the E5CN-□1□□□U (1 auxiliary output), the E5CN-□2□□□U (2 auxiliary outputs), E5GN-□1□□□ (1 auxiliary output), and E5GN-□2□□□ (2 auxiliary outputs).

Alarms can also be used by setting the Control Output 1 Assignment or Control Output 2 Assignment parameter to any of the alarms from alarm 1 to 3. The alarm output condition is determined by a combination of the alarm type, alarm value, alarm hysteresis, and the standby sequence. For details, refer to 4-2 Alarm Hysteresis.

PV Change Rate Alarm

The change width can be found for PV input values in any set period. Differences with previous values in each set period are calculated, and an alarm is output if the result exceeds the alarm value. The PV rate of change calculation period can be set in units of 250 ms.

If a positive value is set for the alarm value, the PV will operate as a change rate alarm in the rising direction. If a negative value is set, the PV will operate as a change rate alarm in the falling direction.

Precaution

If a shorter PV rate of change calculation period is set, outputs set for the PV change rate alarm function may repeatedly turn ON and OFF for a short period of time. It is therefore recommended that the PV change rate alarm be used with the alarm latch turned ON.

3-10 Using Heater Burnout, Heater Short, and Heater Overcurrent Alarms

3-10-1 Heater Burnout, Heater Short, and Heater Overcurrent Alarm Operations

Heater burnout detection and heater overcurrent detection are executed by measuring heater current while the control output (heating) is ON, and heater short detection is executed by measuring heater current while it is OFF. For details, refer to the following table. (Heater burnout detection, heater short detection, and heater overcurrent detection cannot be used with the control output for cooling.)

Control output (heating) status		Power to heater	HB alarm output	HS alarm output	Heater overcurrent alarm output
Control output (heating)	Operation indicator	Power to heater	HB alarm output	HS alarm output	Heater overcurrent alarm output
ON	Lit	Yes (Normal) (See note 1.)	OFF	---	---
ON	Lit	No (Heater burnout)	ON	---	---
OFF	Not lit	Yes (HS alarm)	---	ON	---
OFF	Not lit	No (Normal) (See note 2.)	---	OFF	---
ON	Lit	Normal	---	---	OFF
ON	Lit	Heater overcurrent status (See note 3.)	---	---	ON

OMRON E5EN - 3-10-1 Heater Burnout, Heater Short, and Heater Overcurrent Alarm Operations - 1

Note

(1) In the above diagram, power is considered to be ON (normal) if the heater current is greater than the heater burnout detection current during the Ton interval. If the heater is burned out, the measured current decreases and falls below the heater burnout detection value. The output is then activated as the heater burnout alarm.
(2) In the above diagram, power is considered to be OFF (normal) if the leakage current is less than the HS alarm current during the Toff interval. If the SSR output is short-circuited, the measured current increases beyond the HS alarm value. The output is then activated as the HS alarm.
(3) In the above diagram, it is regarded as normal when the heater current is less than the heater overcurrent detection current during the Ton period. Current is increased when excessive current flows to the heater, causing the heater overcurrent detection value to be exceeded and an OC (heater overcurrent) alarm to be output.
(4) Heater burnout and heater overcurrent are not detected if the control output (heating) ON time (Ton) is 100 ms or less.
(5) HS alarms are not detected if the control output (heating) OFF time (Toff) is 100 ms or less.

For Controllers with heater burnout, HS, and heater overcurrent alarms, an OR output is established between the ALM 1 function and the alarms. If the ALM1 function is to be used for the heater burnout, HS, and heater overcurrent alarms only, set 0 as the alarm 1 type (i.e., do not use ALM1).
Turn the heater power ON simultaneously or before turning ON the E5□N power. If the heater power is turned ON after turning ON the E5AN power, the HB alarm will be activated.
Control is continued even when the heater burnout, HS, or heater overcurrent alarm is active.
The rated current value may sometimes differ slightly from the actual current flowing to the heater.

Use the Heater Current 1 Value Monitor, Heater Current 2 Value Monitor, Leakage Current 1 Monitor, and Leakage Current 2 Monitor parameters to check the actual current being used.

If there is little difference between the current in normal and abnormal states, detection may become unstable. To stabilize detection, set a current value difference of at least 1.0A for heaters of less than 10.0A , and at least 2.5A for heaters of 10.0A or more. If the heater current is too low, loop the load line several times through a CT, as shown in the diagram below. Looping it through once will double the detection current.

OMRON E5EN - Note - 1

3-10-2 Installing Current Transformers (CT)

This function can be used with E5□N models that have the HB alarm, HS alarm, and OC alarm.

For the E5CN, connect the CT in advance to terminals 14 and 15 (CT1), or 13 and 15 (CT2). For the E5AN/E5EN, connect the CT in advance to terminals 14 and 15 (CT1) or 15 and 16 (CT2). For the E5GN, connect the CT in advance to terminals 7 and 8 (CT1). Then pass the heater power line through the CT's hole. For specifications, models and dimensions of current transformers that can be used with this Controller, refer to Appendix Current Transformer (CT) on page 279.

Single-phase Heaters

For single-phase heaters, install the CT in the position shown in the following diagram.

OMRON E5EN - Single-phase Heaters - 1

Three-phase Heaters (E5AN-□□HH□-N, E5EN-□□HH□-N, and E53-CN□□HHN2 (for E5CN) 3-phase Heater Detection Models)

When a 3-phase power supply is used, regardless of the types of connecting lines, two current transformers (CTs) are required to detect heater burnout, HS, and OC.

1,2,3... 1. Delta connecting lines: Refer to the following diagram for CT installation positions.

3-10-3 Calculating Detection Current Values

Calculate the set value using the following equation:

$$ \text {H e a t e r B u r n o u t D e t e c t i o n 1 / 2 s e t v a l u e} = \frac {\text {N o r m a l c u r r e n t v a l u e} + \text {B u r n o u t c u r r e n t v a l u e}}{2} $$

$$ H S A l a r m 1 / 2 s e t v a l u e = \frac {\text {L e a k a g e c u r r e n t v a l u e (o u t p u t O F F) + H S c u r r e n t v a l u e}}{2} $$

$$ \text {H e a t e r o v e r c u r r e n t 1 / 2 s e t v a l u e} = \frac {\text {N o r m a l c u r r e n t v a l u e} + \text {O v e r c u r r e n t v a l u e}}{2} $$

To set the current for heater burnout when two or more heaters are connected through the CT, use the value from when the heater with the smallest current burns out. If all of the heaters have the same current, use the value from when any one of them burns out.
Make sure that the following conditions are satisfied:

Heater with a current of less than 10.0 A:

(Current value at normal operation) - (Current value at heater burnout) ≥ 1 A

When the difference is less than 1 A, detection is unstable.

Heater with a current of 10.0 A or more:

(Current value at normal operation) - (Current value at heater burnout) ≥ 2.5 A

When the difference is less than 2.5A , detection is unstable.

The setting range is 0.1 to 49.9 A. Heater burnout, HS, and heater overcurrent are not detected when the set value is 0.0 or 50.0. When the set value is 0.0, the heater burnout alarm is always OFF, the HS alarm is always ON, and the heater overcurrent alarm is always ON. When the set value is 50.0, the heater burnout alarm is always ON, the HS alarm is always OFF, and the heater overcurrent alarm is always OFF.
Set the total current value for normal heater operation to 50 A or less. When a current value of 55.0 A is exceeded, FFFF is displayed in the Heater Current 1 (or 2) Value Monitor and Leakage Current 1 (or 2) Monitor parameters.

3-10-4 Application Examples

OMRON E5EN - 3-10-4 Application Examples - 1
Single-phase Heaters

OMRON E5EN - 3-10-4 Application Examples - 2
Example: Using a 200-VAC, 1-kW Heater

The heater power supply provides 5 A when the current is normal, and 0 A when there is a burnout, so the heater burnout detection current is calculated as follows:

$$ \begin{array}{l} \text {H e a t e r b u r n o u t d e t e c t i o n c u r r e n t} = \frac {\text {(N o r m a l c u r r e n t)} + \text {(H e a t e r b u r n o u t c u r r e n t)}}{2} \ = \frac {5 + 0}{2} = 2. 5 [ A ] \ \end{array} $$

Example: Using Three 200-VAC, 1-kW Heaters

OMRON E5EN - 3-10-4 Application Examples - 3

OMRON E5EN - 3-10-4 Application Examples - 4

The heater power supply provides 15 A when the current is normal, and 10 A when there is a burnout, so the heater burnout detection current is calculated as follows:

Heater burnout detection current = (Normal current) + (Heater burnout current)2

$$ = \frac {1 5 + 1 0}{2} = 1 2. 5 [ A ] $$

Three-phase Heaters

Delta Connecting Lines

Example: Using Three 200-VAC, 2-kW Heaters

OMRON E5EN - Delta Connecting Lines - 1

The current when each phase is normal is 17.3 A ( ≈ 3 × 10 A).

OMRON E5EN - Delta Connecting Lines - 2
Current when there is a burnout = 10A× 3×

OMRON E5EN - Delta Connecting Lines - 3
Current when there is a burnout = 10A× 3×

The heater burnout current when there is a burnout at the load line is as follows:

(1 / 3) = 10A

(Heater burnout detection current) = (17.3 + 15) / 2 ≈ 16.1 [A]

The heater burnout current when there is a burnout at the load is as follows:

(Heater burnout detection current) = (17.3 + 10) / 2 ≈ 13.65 [A]

To enable detection in either case, use 16.1 A as the heater burnout detection current.

Star Connecting Lines

Example: Using Three 200-VAC, 2-kW Heaters

OMRON E5EN - Star Connecting Lines - 1

The current when each phase is normal is 5.8A (≈ 10A × (1 / 3))

OMRON E5EN - Star Connecting Lines - 2
Current when there is a burnout = 10A× (1 / 3)
× ( 3/2) = 5 A

OMRON E5EN - Star Connecting Lines - 3
Current when there is a burnout = 10A× (1 / 3)
× (3 / 2) = 5A

The heater burnout detection current for this connecting line is 5.4 A ( = (5.8 + 5) / 2 ).

The heater burnout current when there is a burnout at the common is as follows:

Heater burnout detection current = (10 + 5) / 2 ≈ 7.5 [A]

The heater burnout current when there is a burnout at the load is as follows: Heater burnout detection current = (10 + 0) / 2 ≈ 5 [A]

To enable detection in either case, use 7.5 A as the heater burnout detection current.

4-1 Shifting Input Values

4-1-1 Shifting Inputs

The input shift matched to the sensor currently selected in the Input Type parameter is displayed.

A 2-point shift is applied for infrared temperature sensors. A 2-point shift can also be used if the Input Shift Type parameter (advanced function setting level) is set to INS2 for a thermocouple or platinum resistance thermometer.
There is no shift for analog inputs. Use scaling for fine adjustments.

One-point shift

OMRON E5EN - One-point shift - 1

Temperature Input Shift

With a 1-point shift, the value set for the Temperature Input Shift parameter (adjustment level) is applied to each point in the entire temperature input range. For example, if the input shift value is set to 1.2^ , the process value is treated as 201.2^ after the input shift is applied when the measured process value is 200^ .

Upper-limit Temperature Input Shift Value

OMRON E5EN - Two-point shift - 2

Lower-limit Temperature Input Shift Value

Separate shift values can be set for the upper limit and lower limit of the sensor input range for an infrared sensor as well as for a thermocouple or platinum resistance thermometer with the Input Shift Type parameter set to INS2. If different shift values are set for the upper limit and lower limit, then the slope of the line will be different before and after applying the input shift. For example, if the upper-limit value is set to 2^ and the lower-limit value is set to 1^ , the input temperature will be shifted by 1.5^ for a 50% input, i.e., by the average of the upper-limit and lower-limit values.
Set the upper-limit value in the Upper-limit Temperature Input Shift Value parameter and the lower-limit value in the Lower-limit Temperature Input Shift Value parameter.

OMRON E5EN - Two-point shift - 3

4-1-2 How to Calculate Input Shift Values for a 2-point Shift

When an ES1B Infrared Temperature Sensor is connected to the E5CN, an offset of several degrees to several tens of a degree can occur.

For this reason, offset the readout value using a 1-point or 2-point shift as described in this section. This offset occurs because a bias current for detecting a Controller sensor error flows to the output impedance of the infrared temperature sensor.

Preparations

1,2,3...

Set a temperature range matching the input specifications of the infrared temperature sensor. (The ES1B can be used with the E5☐N only for a thermocouple/resistance thermometer universal input.)
Prepare a thermometer capable of measuring the temperature of the control target as shown in Figure 1 so that a 1-point shift or 2-point shift can be carried out.
The E53-CN□□P□N2 (for E5CN), E5AN-□□P□-N, or E5EN-□□P□-N has a built-in external power supply for ES1B Infrared Temperature Sensors. These E5CN models can be used as the power supply when using ES1B. When ES1B are used with other E5CN models, provide a separate power supply for the Infrared Temperature Sensors.

Lower-limit Temperature Input Shift Value

In the configuration shown in Figure 1, bring the set point to near the value at which the temperature of the control target is to be controlled. Assume that the control target temperature (C) and the thermometer temperature (B) are the same.
Check the thermometer temperature (B) and the Controller readout (A). Subtract the Controller readout temperature (A) from the thermometer temperature (B), and set N5L and N5H to the result as the input shift value. The shift is illustrated in Figure 2.
After setting the input shift values, check the Controller readout (A) and the thermometer temperature (B). If they are almost the same, this completes shifting the temperature input.

OMRON E5EN - 1,2,3... - 3
Figure 2 Illustration of 1-Point Shift

Method for a 2-point Shift

Use a 2-point input shift if you want to increase the accuracy of the readout values across the range of the Sensor.

1,2,3...

Shift the Controller readout at two points, near room temperature and near the value at which the temperature of the control target is to be controlled. For this reason, check the thermometer temperature (B) and Controller readout (A) with the thermometer temperature near room temperature and near the set point.

2.

Y1 is the Controller readout at room temperature before shifting and X1 is the Controller readout at room temperature after shifting.
Y2 is the Controller readout at the set temperature before shifting and X2 is the Controller readout at the set temperature after shifting.
Set the upper-limit temperature input shift and the lower-limit temperature input shift using the following formulas based on the temperatures before shifting (Y1 and Y2), the temperatures after shifting (X1 and X2), the set temperature upper limit (YH), and the set temperature lower limit (YL). The shift is illustrated in Figure 3.

OMRON E5EN - 2. - 1
Figure 3 Illustration of 2-Point Shift

a. Lower-limit temperature input shift value

$$ \bar {L} N 5 L = \frac {Y L - Y 1}{Y 2 - Y 1} \times \left{\left(X 2 - Y 2\right) - \left(X 1 - Y 1\right) \right} + \left(X 1 - Y 1\right) $$

b. Upper-limit temperature input shift value

$$ \bar {L} N 5 H = \frac {Y H - Y 1}{Y 2 - Y 1} \times \left{\left(X 2 - Y 2\right) - \left(X 1 - Y 1\right) \right} + \left(X 1 - Y 1\right) $$

After setting the calculated values to N5L and N5H , check the Controller readout (A) and thermometer temperature (B).
Here, offsets are set at two points, near room temperature and near the set point. To improve accuracy within the measurement temperature range, another point in the measurement temperature range other than the set point should be set instead of room temperature.

Example of a 2-point Temperature Input Shift

In this example, we use the ES1B K 0 to 260^ specification. In equations 1 and 2, the set temperature lower limit YL is 0^ and the set temperature upper limit YH is 260^ . Check the temperature of the control target.

The temperature input offset values can be calculated as shown below when the Controller readout Y1 is 40^ for a room temperature X1 of 25^ and when the Controller readout Y2 is 105^ for a set point temperature X2 of 110^ .

Lower-limit Temperature Input Shift Value

4-2 Alarm Hysteresis

The hysteresis of alarm outputs when alarms are switched ON/OFF can be set as follows:

OMRON E5EN - 4-2 Alarm Hysteresis - 1

OMRON E5EN - 4-2 Alarm Hysteresis - 2

Alarm hysteresis is set independently for each alarm in the Alarm Hysteresis 1 to Alarm Hysteresis 3 parameters (initial setting level).
The default is 0.2(^ / ^) for Controllers with Thermocouple/Resistance Thermometer Universal Inputs and 0.02% FS for Controllers with Analog Inputs.

4-2-1 Standby Sequence

The standby sequence can be used so that an alarm will not be output until the process value leaves the alarm range once and then enters it again.
For example, with a lower limit alarm, the process value will normally be below the set point, i.e., within the alarm range, when the power supply is turned ON, causing an alarm to be output.

If the lower limit alarm with a standby sequence is selected, an alarm will not be output until the process value increases above the alarm set value, i.e., until it leaves the alarm range, and then falls back below the alarm set value.

Restart

The standby sequence is canceled when an alarm is output. It is, however, restarted later by the Standby Sequence Reset parameter (advanced function setting level). For details, refer to the Standby Sequence Reset parameter in SECTION 5 Parameters.

4-2-2 Alarm Latch

The alarm latch can be used to keep the alarm output ON until the latch is canceled regardless of the temperature once the alarm output has turned ON.

Any of the following methods can be used to clear the alarm latch.

Turn OFF the power supply. (The alarm latch is also cleared by switching to the initial setting level, communications setting level, advanced function setting level, or calibration level.)
Use the PF Key.
Use an event input.

For details on setting the PF Key, refer to 4-19 Setting the PF Key. For details on setting events, refer to 4-5 Using Event Inputs.

4-4 Executing Heating/Cooling Control

4-4-1 Heating/Cooling Control

Heating/cooling control can be used on the E5CN-□M□-500 (with an E53-CNQ□□N2), E5CN-□2M□-500, E5AN-□3M□-500-N or E5EN-□3M□-500-N. Heating/cooling control operates when H - L (heating/cooling) is selected for the Standard or Heating/Cooling parameter.

The following functions are assigned to outputs in the initial status.

Parameter name	Symbol	Initial status
Control Output 1 Assignment	aUb1	Control output for heating
Control Output 2 Assignment	aUb2	Not assigned.
Auxiliary Output 1 Assignment	5Ub1	Alarm 1
Auxiliary Output 2 Assignment	5Ub2	Alarm 2
Auxiliary Output 3 Assignment (E5AN/EN only)	5Ub3	Alarm 3

Each output assignment is automatically initialized as shown below when the control mode is changed.

Example: E5CN

Parameter name	Symbol	Without control output 2		With control output 2
Parameter name	Symbol	Standard	Heating/cooling	Standard	Heating/cooling
Control Output 1 Assignment	$ \bar{a} u_{\text{E}} $	Control output (heating)	Control output (heating)	Control output (heating)	Control output (heating)

Auxiliary Output 2 Assignment	$ \bar{S} u_{\text{B}} $	Alarm 2 (See note 3.)	Control output (coo-ing) (See note 3.)	Alarm 2	Alarm 2

Example: E5GN

Parameter name	Symbol	Standard	Heating/cooling
Control Output 1 Assignment	$ \bar{a}U_{\text{ct}} $	Control output (heating)	Control output (heating)
Auxiliary Output 1 Assignment	$ \bar{S}U_{\text{ct}} $	Alarm 1 (See note 2.)	Control output (coo-ing)
Auxiliary Output 2 Assignment	$ \bar{S}U_{\text{ct}} $	Alarm 2	Alarm 2

Note

(1) No parameter assignment is displayed because there is no control output 2.
(2) The output set for the Auxiliary Output 1 Assignment parameter becomes the program END output unless the program pattern is OFF.
(3) For the E5AN/EN, the Auxiliary Output 3 Assignment parameter is set for control output (cooling) (the Auxiliary Output 2 Assignment parameter is set for alarm 2).
- The heating/cooling operation of the control outputs will switch when the Direct/Reverse Operation parameter is set to "direct."
- When DRS (Invert Direct/Reverse Operation) is assigned for an Event Input Assignment (1 or 2), control will start with the contents set for the Direct/Reverse Operation parameter inverted when the event input turns ON, and with the contents left according to the setting when the event input turns OFF. For details on event inputs and control combined with the Direct/Reverse Operation parameter, refer to Control by Inverting Direct/ Reverse Operation on page 103.
- When heating/cooling control is selected, the Dead Band and Cooling Coefficient parameters can be used.

Dead Band

For heating/cooling control, the dead band is set with the set point as its center. The dead band width is the set value of the Dead Band parameter (adjustment level). Setting a negative value produces an overlapping band.
If an overlapping band is set, the bumpless function may not operate when switching between manual operation and automatic operation.
The default is 0.0 EU for Controllers with Thermocouple/Resistance Thermometer Universal Inputs and 0.00% FS for Controllers with Analog Inputs.

OMRON E5EN - Dead Band - 1

OMRON E5EN - Dead Band - 2

Cooling Coefficient

If the heating characteristics and cooling characteristics of the control object are very different and good control characteristics cannot be achieved with the same PID constants, the cooling coefficient can be used to adjust the proportional band (P) for the control output assigned to the cooling side. Use this to achieve balanced control between the heating side and cooling side. The proportional bands (P) for the control outputs assigned to the heating/cooling sides can be calculated using the following equations.

P for control output assigned to heating side =

P for control output assigned to cooling side = P for control output assigned to heating side × cooling coefficient

The cooling coefficient is multiplied by the P for the control output assigned to the heating side to obtain control with characteristics that differ from those of the control output assigned to the heating side.

OMRON E5EN - Cooling Coefficient - 1

OMRON E5EN - Cooling Coefficient - 2

Automatic Cooling Coefficient Adjustment

By executing AT during heating/cooling control, the cooling coefficient can be automatically calculated along with the PID parameters.

Parameter name	Setting rage	Default
Automatic Cooling Coefficient Adjustment	OFF: Disabled, ON: Enabled	OFF

Note

If there is strong non-linear gain for the cooling characteristics, such as when cooling water boils for cooling control, it may not be possible to obtain the optimum cooling coefficient at the Controller, and control may take the form of

oscillating waves. If that occurs, increase the proportional band or the cooling coefficient to improve control.

4-6 Setting the SP Upper and Lower Limit Values

4-6-1 Set Point Limiter

The setting range of the set point is limited by the set point limiter. This function can be used to prevent setting incorrect process values. The set point limiter is used to prevent the control target from reaching abnormal temperatures. If the set point is not within the range set for the set point limiter as the result of changes to the Set Point Upper Limit or Set Point Lower Limit parameter, the set point will automatically be change to a value within the set

range. The upper- and lower-limit values of the set point limiter are set using the Set Point Upper Limit and Set Point Lower Limit parameters in the initial setting level. When the set point limiter is reset, the set point is forcibly changed to the upper- or lower-limit value of the set point limiter if the set point is out of the limiter range. Also, when the input type and the temperature unit, scaling upper-limit value, or lower-limit value are changed, the set point limiter is forcibly reset to the input setting range or the scaling upper- or lower-limit value.

OMRON E5EN - 4-6-1 Set Point Limiter - 1

Parameters

Symbol	Parameter: level	Description
SL-H	Set Point Upper Limit: Initial setting level	To limit the SP setting

4-7 Using the SP Ramp Function to Limit the SP Change Rate 4-7-1 SP Ramp

The SP ramp function is used to restrict the width of changes in the set point as a rate of change. When the SP ramp function is enabled and the change width exceeds the specified rate of change, an area where the set point is restricted will be created, as shown in the following diagram.

During the SP ramp, control will be performed not for the specified set point but rather for the set point restricted by the rate of change set for the SP ramp function.

OMRON E5EN - 4-7 Using the SP Ramp Function to Limit the SP Change Rate 4-7-1 SP Ramp - 1

The rate of change during SP ramp is specified using the SP Ramp Set Value and SP Ramp Time Unit parameters. The SP Ramp Set Value parameter is set to OFF by default, i.e., the SP ramp function is disabled.

Changes in the ramp set point can be monitored in the Set Point During SP Ramp parameter (operation level). Use this parameter when monitoring SP ramp operation.

The SP ramp function operates in the same way when switching the set point using the multi-SP function.

$ \overline{\mathsf{RL}}\overline{\mathsf{SP}} $	Alarm SP Selection: Advanced function setting level	Alarm SP selection

Operation at Startup

If the SP ramp function is enabled when the Controller is turned ON or when switching from STOP to RUN mode, the process value reaches the set point using the SP ramp function in the same way as when the set point is changed. In this case, operation is carried out with the process value treated as the set point before the change was made. The direction of the SP ramp changes according to the relationship between the process value and the set point.

OMRON E5EN - Operation at Startup - 1

Restrictions during SP Ramp Operation

Execution of auto-tuning starts after the end of the SP ramp.
When control is stopped or an error occurs, the SP ramp function is disabled.

Alarms during SP Ramp Operation

The operation of alarms during SP ramp operation depends on whether alarms are set to be based on the ramp set point or the target set point (refer to the following diagrams). The set point to be used is set in the Alarm SP Selection parameter. (Refer to page 244.)

4-11 Alarm Delays

4-11-1 Alarm Delays

Delays can be set for the alarm outputs. ON and OFF delays can be set separately for alarms 1, 2, and 3. The ON and OFF delays for alarm 1 function only for the alarm function. If the alarm 1 function is set to be output as an OR with other alarms (i.e., the heater burnout alarm, HS alarm, heater overcurrent alarm, or input error output alarm), delays cannot be set for the other alarms. The ON and OFF delays for alarms 1, 2, and 3 also apply to the individual SUB1, SUB2, and SUB3 indicators and to communications status. The alarm ON delays will also function when power is turned ON or when moving from the initial setting level to operation level (e.g., to software resets). All outputs will turn OFF and the OFF delays will not function when moving to the initial setting level or when an alarm is output for a A/D converter error.

Operation of Alarm ON and OFF Delays (for an Upper-limit Alarm)

OMRON E5EN - Operation of Alarm ON and OFF Delays (for an Upper-limit Alarm) - 1

The alarm will not turn ON if the time that the alarm is ON is equal to or less than the ON delay set time. Also, the alarm will not turn OFF if the time that the alarm is OFF is equal to or less than the OFF delay set time.
If an alarm turns OFF and then back ON during the ON delay time, the time will be remeasured from the last time the alarm turns ON. Also, if an alarm turns ON and then back OFF during the OFF delay time, the time will be remeasured from the last time the alarm turns OFF.

Parameter name	Symbol	Set (monitor) values
Alarm 1 ON Delay	R10N	0 to 999 (s)
Alarm 2 ON Delay	R20N	0 to 999 (s)
Alarm 3 ON Delay	R30N	0 to 999 (s)

4-12 Loop Burnout Alarm

4-12-1 Loop Burnout Alarm (LBA)

With a loop burnout alarm, there is assumed to be an error in the control loop if the control deviation (SP - PV) is greater than the threshold set in the LBA Level parameter and if the control deviation is not reduced by at least the value set in the LBA Detection Band parameter within the LBA detection time.
Loop burnout alarms are detected at the following times.

OMRON E5EN - 4-12-1 Loop Burnout Alarm (LBA) - 1

If the control deviation is reduced in the area between 1 and 2 (i.e., the set point is approached) and the amount the control deviation is reduced is at least equal to the LBA band, the loop burnout alarm will remain OFF.

The process value is within the LBA level between 3 and 4, and thus loop burnout alarms will not be detected. (The loop burnout alarm will remain OFF.)

If the process value is outside the LBA level between 4 and 5 and the control deviation is not reduced by at least the LBA band within the LBA detection time, the loop burnout alarm will turn ON.

If the control deviation is reduced in the area between 5 and 6 (i.e., the set point is approached) and the amount the control deviation is reduced is at least equal to the LBA band, the loop burnout alarm will turn OFF.

If the control deviation is reduced in the area between 6 and 7 (i.e., the set point is approached) and the amount the control deviation is reduced is less than the LBA band, the loop burnout alarm will turn ON.

If the LBA detection time, LBA level, LBA detection band, and PID settings are not appropriate, alarms may be detected inappropriately or alarms may not be output when necessary.
Loop burnout alarms may be detected if unexpectedly large disturbances occur continuously and a large deviation does not decrease.
If a loop burnout occurs when the set point is near the ambient temperature, the temperature deviation in a steady state may be less than the LBA level, preventing detection of the loop burnout.
If the set point is so high or low that it cannot be reached even with a saturated manipulated variable, a temperature deviation may remain even in a steady state and a loop burnout may be detected.
Detection is not possible if a fault occurs that causes an increase in temperature while control is being applied to increase the temperature (e.g., an SSR short-circuit fault).
Detection is not possible if a fault occurs that causes a decrease in temperature while control is being applied to decrease the temperature (e.g., a heater burnout fault).

Parameters Related to Loop Burnout Alarms

Parameter name	Symbol	Setting range		Remarks
LBA Detection Time	LbR	0 to 9999 (s)		Setting 0 disables the LBA function.
LBA Level	LbRL	Controllers with Thermo-couple/Resistance Thermometer Universal Inputs	0.1 to 999.9 (°C/°F) (See note.)	Default: 8.0 (°C/°F)
LBA Level	LbRL	Controllers with Analog Inputs	0.01 to 99.99 (%FS)	Default: 10.00% FS
LBA Band	LbRb	Controllers with Thermo-couple/Resistance Thermometer Universal Inputs	0.0 to 999.9 (°C/°F) (See note.)	Default: 3.0 (°C/°F)
LBA Band	LbRb	Controllers with Analog Inputs	0.00 to 99.99 (%FS)	Default: 0.20% FS

Note Set "None" as the unit for analog inputs.

A loop burnout alarm can be output by setting the alarm 1 type to 12 (LBA).
A setting of 12 (LBA) can be set for alarm 2 or alarm 3, but the setting will be disabled.
Loop burnouts are not detected during SP ramp operation.
Loop burnouts are not detected during auto-tuning, manual operation, or while stopped.
If the alarm 1 latch is set to ON, the latch will be effective for the loop burnout alarm.

Automatically Setting the LBA Detection Time

The LBA detection time is automatically set by auto-tuning. (It is not set automatically, however, for heating/cooling control.)
If the optimum LBA detection time is not obtained by auto-tuning, set the LBA Detection Time parameter (advanced function setting level).

Determining the LBA Detection Time

1,2,3...

To manually set the LBA detection time, set the LBA Detection Time parameter to twice the LBA reference time given below.
Set the output to the maximum value.
Measure the time required for the width of change in the input to reach the LBA band.

OMRON E5EN - Determining the LBA Detection Time - 1

Set the LBA Detection Time parameter to two times the measured time.

LBA Level

Set the control deviation when the control loop is working properly.
The default is 8.0(^ C / ^ F) for Controllers with Thermocouple/Resistance Thermometer Universal Inputs and 10.00 % FS for Controllers with Analog Inputs.

LBA Band

There is assumed to be an error in the control loop if the control deviation is greater than the threshold set in the LBA Level parameter and if the control deviation does not change by at least the value set in the LBA Band parameter.
The default is 3.0(^ / ^) for Controllers with Thermocouple/Resistance Thermometer Universal Inputs and 0.20% FS for Controllers with Analog Inputs.

Operating Procedure

Perform the following procedure to use the loop burnout alarm.

In this example, the LBA detection time is set to 10, the LBA level is set to 8.0, and the LBA band is set to 3.0.

4-13 Performing Manual Control

4-13-1 Manual Operation

The manipulated variable can be set in manual mode if the PV/MV parameter is displayed in the manual control level. The final MV used in automatic mode will be used as the initial manual MV when moving from automatic mode to manual mode. In manual mode, the change value will be saved immediately and reflected in the actual MV.
The automatic display return function will not operate in manual mode.
Balanceless-bumpless operation will be performed for the MV when switching from manual operation to automatic operation. (See note.)
If a power interruption occurs during manual operation, manual operation will be restarted when power is restored using the same MV as when power was interrupted.
Switching between automatic and manual operation is possible for a maximum of one million times.
Manual operation can be used only for PID control.

Note

In balanceless-bumpless operation, the MV before switching is used initially after the switch and then gradually changed to achieve the proper value after switch to prevent radical changes in the MV after switching operation.

The overall manual operation is illustrated in the following figure.

OMRON E5EN - Note - 1

4-14 Using the Transfer Output

4-14-1 Transfer Output Function

To use a transfer output, change the setting for the Transfer Type parameter to anything other than OFF. (This will enable the Transfer Output Upper Limit and Transfer Output Lower Limit parameters.)
The operation is shown in the following table.

Control output 1	Control output 2	Transfer output destination
Current output	None, relay output, voltage output (for driving SSR)	Control output 1
Relay output, voltage output (for driving SSR)	None, relay output, voltage output (for driving SSR)	None

■ Precision and User Calibration

	Precision	User calibration
Simple transfer out-put	Not specified.	Not supported.

Transfer Output Type

Transfer output type	Symbol	Setting range
OFF (See note 1.)	$\overline{a}FF$	---
Set point	$5P$	SP lower limit to SP upper limit
Set point during SP ramp	$5P-M$	SP lower limit to SP upper limit
PV	$PV$	Input setting range lower limit to input setting range upper limit or Scaling lower limit to scaling upper limit
MV monitor (heating)	$MV$	-5.0 to 105.0 (heating/cooling control: 0.0 to 105.0) (See note 2.)
MV monitor (cooling)	$\overline{C-MV}$	0.0 to 105.0 (See note 2.)

Note

(1) The default is OFF.

(2) The output value will be different between when the Transfer Output Type parameter is set to a heating control output or cooling control output, and when the Control Output 1 Assignment parameter is set to a heating control output or cooling control output.

Example: When a Current Output Is Set to 4 to 20mA and MV Monitor (Heating) Is Selected

When used as a transfer output, 4.0mA will be output for 0% and 20.0mA will be output for 100% .

When used as a control output, 3.7mA will be output for 0% and 20.3mA will be output for 100% so that the actuator is controlled at 0% or 100% .

Output current (mA)
OMRON E5EN - Note - 1
(The above graph is for when the linear current output type is set to 4 to 20mA .)

Transfer Scaling

Reverse scaling is possible by setting the Transfer Output Lower Limit parameter larger than the Transfer Output Upper Limit parameter. If the Transfer Output Lower Limit and Transfer Output Upper Limit parameters are set to the same value when 4 to 20mA is set, the transfer output will be output continuously at 0% (4 mA).
If the SP, SP during SP ramp, or PV is selected, the Transfer Output Lower Limit and Transfer Output Upper Limit parameters will be forcibly initialized to the respective upper and lower setting limits for changes in the upper and lower limits of the SP limiter and the temperature unit. If the MV for heating or MV for cooling is selected, the Transfer Output Lower Limit and Transfer Output Upper Limit parameters will be initialized to 100.0 and 0.0, respectively, when a switch is made between standard control and heating/cooling control using the Standard or Heating/Cooling parameter.
The output current when the linear current type is set to 4 to 20mA , the transfer output upper limit is set to 90.0, and the transfer output lower limit is set to 10.0 is shown in the following graph.
For scaling from 0.0% to 100.0% , the output for -5.0 to 0.0 will be the same value as for 0.0% , and the output for 100.0 to 105.0 will be the same value as for 100.0% .

4-15 Using the Simple Program Function

4-15-1 Simple Program Function

The simple program function can be used for the following type of control.

OMRON E5EN - 4-15-1 Simple Program Function - 1

The program will start when the Program Start parameter is changed from RSET to STRT. END will be displayed on the No. 2 display and the output assigned as the program end output will turn ON after the time set in the Soak Time parameter has expired in the wait band. The Program Pattern parameter can be used to select moving to STOP mode or continuing operation in RUN mode after the program ends.

Parameters Related to the Simple Program Function

Parameter name	Symbol	Set (monitor) values	Unit	Display level
Program Pattern	PERN	OFF, STOP, CONT	---	Initial setting level
Program Start	PRSET	RSET, STRT	---	Operation level
Soak Time	S0AHK	1 to 9999	min or h	Adjustment level
Soak Time Unit	t - U	m (minutes)/h (hours)	---	Advanced function setting level
Wait Band	Wt - b	OFF or 0.1 to 999.9 (See note 2.)	°C or °F (See notes 1 and 2.)	Adjustment level
Soak Time Remain Monitor	SkerR	0 to 9999	min or h	Operation level

Note

(1) Set for Controllers with Thermocouple/Resistance Thermometer Universal Inputs. Set "None" as the unit for Controllers with Analog Inputs.
(2) The setting unit of the Wait Band parameter is %FS for Controllers with Analog Inputs and the setting range is OFF or 0.01 to 99.99.

Program Pattern

Either of two program patterns can be selected. The simple program operation will not be performed if the Program Pattern parameter is set to OFF.

■ Pattern 1 (STOP)

Control will stop and the STOP mode will be entered when the program has ended.

OMRON E5EN - ■ Pattern 1 (STOP) - 1

Pattern 2(CONT)

Control will continue in RUN mode when the program has ended.

OMRON E5EN - Pattern 2(CONT) - 1

Starting Method

Any of the following three methods can be used to start the simple program.

Setting the Program Start parameter to STRT.
Turning ON an event input. (The program start must be assigned to an event input. See note.)
Starting with an Operation Command using communications. (When the program start is not assigned to an event input.)

Note

When the simple program is started and reset, writing is performed to EEPROM. Be sure to consider the write life (1 million writes) of the EEPROM in the system design. When the program start is assigned to an event input, the Program Start parameter will function as a monitor display, and the RSET/STRT displays can be used to check when the event input has started or reset the simple program. When this is done, the Program Start parameter functions as a monitor display only and cannot be changed using key operations. If the Program Pattern parameter is set to OFF, the event input assignment setting will be initialized to "None."

Soak Time and Wait Band

OMRON E5EN - Soak Time and Wait Band - 1

The wait band is the band within which the process value is stable in respect to the set point. The soak time is measured within the wait band. The timer that measures the soak time operates only when the process value is within the wait band around the set point (i.e., SP ± wait band). In the following diagram, the timer will be stopped between the start and (1), (2) and (3), and (4) and (5) and will measure the time only between (1) and (2), (3) and (4), and (5) and the end.

Note

If the wait band is set to OFF, the wait band will be treated as infinity and the timer will measure time continuously after changing from RSET to STRT.

4-15-2 Operation at the Program End

Display at the Program End

When the program ends, the process value will be displayed on the No. 1 display (see note) and the set point and "end" will be alternately displayed on the No. 2 display at 0.5 s intervals.

Note One of the following displays: PV/SP, PV only, or PV/MV.

OMRON E5EN - Display at the Program End - 1

Program End Output

The output assignment parameters can be used to assign the program END output to any output. The program END output can also be used in communications status.

E5CN/CN-U, E5AN/EN

When the Program Pattern parameter is changed from OFF to STOP or CONT for the E5CN, E5CN-U, E5AN, or E5EN, the Auxiliary Output 1 Assignment parameter will automatically be set to the END output. When the Program Pattern parameter is changed from STOP or CONT to OFF, the Alarm 1 Output Assignment parameter will automatically be initialized to ALM1.

E5GN

When the Program Pattern parameter is changed from OFF to STOP or CONT for the E5GN, the Auxiliary Output 1 Assignment parameter will automatically be set to the END output. When the Program Pattern parameter is changed from STOP or CONT to OFF, the Alarm 1 Output Assignment parameter will automatically be initialized to ALM1. When using heating/cooling control and the Program Pattern parameter is changed from OFF to STOP or CONT, the END output will not be assigned to an output. Use the output assignment parameters to assign the program END output to the desired output.

Clearing the Program End Status

The program END output and display will be cleared when the Program Start parameter is changed from STRT to RSET. The setting is changed from STRT to RSET while the Program Start parameter is displayed.

The program END status can also be cleared using an event. If the program start function is assigned to an event, however, the program end status cannot be cleared from the Program Start parameter display, which will function only as a monitor display.

Operating Procedure

Perform the following procedure to use the simple program function.

In this example, the program pattern will be set to STOP, the soak time to 10 min, and the wait band to 3.

4-16 Output Adjustment Functions

4-16-1 Output Limits

Output limits can be set to control the output using the upper and lower limits to the calculated MV.
The following MV takes priority over the MV limits. Manual MV (See note.)
MV at stop
MV at PV error

OMRON E5EN - 4-16-1 Output Limits - 1

Note When the manual MV limit is enabled, the manual MV will be restricted by the MV limit.

For heating/cooling control, upper and lower limits are set of overall heating/cooling control. (They cannot be set separately for heating/cooling.)

OMRON E5EN - 4-16-1 Output Limits - 2

4-16-2 MV at Stop

The MV when control is stopped can be set.

For heating/cooling control, the MV at stop will apply to the cooling side if the MV is negative and to the heating side if the MV is positive. When setting the MV when control is stopped, set the MV at Stop and Error Addition parameter (advanced function setting level) to ON. The default is 0.0, so an MV will not be output for either standard or heating/cooling control.

Parameter name	Setting range	Unit	Default
MV at STOP	-5.0 to 105.0 for standard control	%	0.00
	-105.0 to 105.0 (heating/cooling control)

Note The order of priority is as follows: Manual MV > MV at stop > MV at PV error.

4-16-3 MV at PV Error

The MV to be output for input errors can be set.

The MV at stop takes priority when stopped and the manual MV takes priority in manual mode.

Parameter name	Setting range	Unit	Default
MV at PV ERROR	-5.0 to 105.0 for standard control	%	0.0
	-105.0 to 105.0 (heating/cooling control)

Note The order of priority is as follows: Manual MV > MV at stop > MV at PV error.

The order of priority of the MVs is illustrated in the following diagram.

OMRON E5EN - 4-16-3 MV at PV Error - 1

Note When the Manual MV Limit Enable parameter is set to ON, the setting range will be the MV lower limit to the MV upper limit.

Extraction of Square Roots

Extraction of Square Root Enable

OMRON E5EN - Extraction of Square Roots - 1

Extraction of Square Root Low-cut Point

OMRON E5EN - Extraction of Square Roots - 2

For analog inputs, the Extraction of Square Root parameter is provided for inputs so that differential pressure-type flow meter signals can be directly input.
The default setting for the Extraction of Square Root parameter is OFF. The Extraction of Square Root Enable parameter must be set to ON in order to use this function.
If the PV input (i.e., the input before extracting the square root) is higher than 0.0% and lower than the low cut point set in the Extraction of Square Root Low-Cut Point parameter, the results of extracting the square root will be 0.0% . If the PV input is lower than 0.0% or higher than 100.0% , extraction of the square root will not be executed, so the result will be equal to the PV input. The low-cut point is set as normalized data for each input, with 0.0 as the lower limit and 100.0 as the upper limit for the input setting range.

These parameters are used to shift the input temperature at two points: an upper-limit temperature and a lower-limit temperature (as opposed to the Temperature Input Shift parameter, which shifts the input temperature by setting the shift for only one point). A 2-point shift enables more accurate offset of the input range compared with a 1-point shift if the input shift values at the upper and lower limits differ.

This parameter sets input shift values for the upper and lower limits (2-point shift) of the input range.

P	Proportional Band	The control must be set to 2-PID control.
L	Integral Time
d	Derivative Time

OMRON E5EN - Related Parameters - 1

These parameters set PID control constants. PID constants are automatically set when AT or ST is executed.

P action: Refers to control in which the MV is proportional to the deviation (control error).

I action: Refers to a control action that is proportional to the time integral of the deviation. With proportional control, there is normally an offset (control error). Proportional action is thus used in combination with integral action. As time passes, this control error disappears, and the control temperature (process value) comes to agree with the set point.

D action: Refers to a control action that is proportional to the time derivative of the control error. The proportional control and integral control correct for errors in the control result, and thus the control system is late in responding to sudden changes in temperature. The derivative action increases the MV in proportion to the slope of the change in the temperature as a corrective action.

Constant: This mode displays orange, red, or green all the time.
Linked to Alarm 1: This mode switches the PV display color from red to green when alarm 1 turns ON or from green to red when alarm 1 turns ON.
Linked to PV stable band: This mode switches the PV display color between red outside the PV stable band and green within PV stable band, or between green outside the PV stable band and red within PV stable band. Set the PV stable band in the PV Stable Band parameter in the advanced function setting level.
The default is R (red).

The following table shows the display functions that can be set using the PV color change function.

6-1 Parameter Structure

To execute user calibration, enter the password "1201" at the Move to Calibration Level parameter in the advanced function setting level. The mode will be changed to the calibration mode, and dU will be displayed.
The Move to Calibration Level parameter may not be displayed when the user is doing the calibration for the first time. If this happens, set the Initial Setting/Communications Protect parameter in the protect level to 0 before moving to the advanced function setting level.
The calibration mode is ended by turning the power OFF.
The parameter calibrations in the calibration mode are structured as shown below.

Controllers with Thermocouple/Resistance Thermometer Universal Inputs

Controllers with an Analog Input

OMRON E5EN - Controllers with an Analog Input - 1

When calibration has been performed after purchase, the user calibration information shown in the following illustration will be displayed when moving to the calibration level.

OMRON E5EN - Controllers with an Analog Input - 2

6-2 User Calibration

The E5CN/CN-U/AN/EN/GN is correctly calibrated before it is shipped from the factory, and normally need not be calibrated by the user.

If, however, it must be calibrated by the user, use the parameters for calibrating temperature input and analog input. OMRON, however, cannot ensure the results of calibration by the user. Also, calibration data is overwritten with the latest calibration results. The default calibration settings cannot be restored after user calibration. Perform user calibration with care.

6-2-1 Calibrating Inputs

The input type selected in the parameter is used for calibration. The input types are as follows:

Controllers with Thermocouple/Resistance Thermometer Universal Inputs

Thermocouple: 16 types
- Infrared temperature sensor: 4 types
- Analog input: 1 type
- Platinum resistance thermometer: 5 types

Controllers with Analog Inputs

Current input: 2 types
Voltage input: 3 types

6-2-2 Registering Calibration Data

The new calibration data for each item is temporarily registered. It can be officially registered as calibration data only when all items have been calibrated to new values. Therefore, be sure to temporarily register all items when you perform the calibration. When the data is registered, it is also recorded that user calibration has been performed.

Prepare separate measuring devices and equipment for calibration. For details on how to handle measuring devices and equipment, refer to the respective instruction manuals.

6-3 Thermocouple Calibration (Thermocouple/Resistance Thermometer Input)

Calibrate according to the type of thermocouple: thermocouple 1 group (input types 5, 7, 11, 12, 15) and thermocouple 2 group (input types 6, 8, 9, 10, 13, 14, 16, 17, 18, 19, 20, 21, 22, 24, 25).
When calibrating, do not cover the bottom of the Controller. Also, do not touch input terminals/pins (terminals 4 and 5 on the E5CN, pins 1 and 2 on the E5CN-U, pins 19 and 20 on the E5AN/E5EN, or pins 11 and 12 on the E5GN) or compensating conductors.

6-3-1 Preparations

OMRON E5EN - 6-3-1 Preparations - 1

Set the cold junction compensator designed for compensation of internal thermocouples to 0^ . Make sure that internal thermocouples are disabled (i.e., that tips are open).
In the above figure, STV indicates a standard DC current/voltage source.
Use the compensating conductor designed for the selected thermocouple. When thermocouples R, S, E, B, W, or PLII or an infrared temperature sensor is used, the cold junction compensator and the compensating conductor can be substituted with the cold junction compensator and the compensating conductor for thermocouple K.

- Connecting the Cold Junction Compensator

Correct process values cannot be obtained if you touch the contact ends of the compensating conductor during calibration of a thermocouple. Accordingly, short-circuit (enable) or open (disable) the tip of the thermocouple inside the cold junction compensator as shown in the figure below to create a contact or non-contact state for the cold junction compensator.

Error Displays

When an error occurs, the error contents are shown on the No. 1 or the No. 2 display.

This section describes how to check error codes on the display, and the actions to be taken to remedy the problems.

5.ERR

Input Error

Meaning

The input value has exceeded the control range. (See note.)

The input type setting is not correct.

The sensor is disconnected or shorted.

The sensor wiring is not correct.

The sensor is not wired.

Note Control Range

Resistance thermometer, thermocouple input: Temperature setting lower limit -20^ to temperature setting upper limit +20^

(Temperature setting lower limit -40^ to temperature setting upper limit +40^ )

ES1B input: Same as input indication range

Analog input -5% to +105% of scaling range

Action

Check the wiring of inputs for miswiring, disconnections, and short-circuits and check the input type.

If no abnormality is found in the wiring and input type, turn the power OFF then back ON again.

If the display remains the same, the Controller must be replaced. If the display is restored, then the probable cause is electrical noise affecting the control system. Check for electrical noise.

Note With resistance thermometer input, a break in the A, B, or B' line is regarded as a disconnection.

Operation at Error

After an error occurs, the error is displayed and the alarm outputs function as if the upper limit has been exceeded.

When the Input Error Output parameter in the advanced function setting level is set to ON, the output assigned to the alarm 1 function turns ON whenever an input error occurs.

An error message is displayed when the PV, PV/SP, or PV/MV is displayed.

Note The control output turns OFF. When the manual MV, MV at stop, or MV at PV error is set, however the control output corresponds to the set value.

CCCCC

Display Range Exceeded

Meaning

Though this is not an error, it is displayed if the process value exceeds the display range when the control range is larger than the display range.

The display ranges are shown below (with decimal points omitted).

When less than -1,999 C C C
When more than 9,999

Action

Control continues, allowing normal operation. The message is displayed when the PV, PV/SP, or PV/MV is displayed.

Troubleshooting

Checking Problems

If the Temperature Controller is not operating normally, check the following points before requesting repairs. If the problem persists, contact your OMRON representative for details on returning the product.

Timing	Status	Meaning	Countermeasures	Page
Turning ON the power for the first time	Temperature unit (°C/F) is flashing.	ST (self-tuning) is in progress (default setting: ON).	This is not a product fault. The temperature unit (°C/F) flashes while ST (self-tuning) is being performed	64
	Temperature error is large. Input error (S.Err display)	Input type mismatch	Check the sensor type and reset the input type correctly.	52
	Temperature error is large. Input error (S.Err display)	Thermometer is not installed properly.	Check the thermometer installation location and polarity and install correctly.	31
	Communications are not possible.	Non-recommended adapter is being used.	Make sure that the connected device is not faulty.	Section 1 of Communications Manual
	Communications are not possible.	Non-recommended adapter is being used.	Make sure that the connected device is not faulty.	(See note.)
During operation	Overshooting Undershooting Hunting	ON/OFF control is enabled (default: ON/OFF control selected).	Select PID control and execute either ST (self-tuning) or AT (auto-tuning). When using self-tuning, turn ON the power supply to the Temperature Controller and load (heater, etc.) at the same time, or turn ON the load power supply first. Accurate self-tuning and optimum control will not be possible if the power supply to the load is turned ON after turning ON the power supply to the Temperature Controller.	62
		Control cycle is longer compared with the speed of rise and fall in temperature	Shorten the control cycle. A shorter control cycle improves control performance, but a cycle of 20 ms minimum is recommended in consideration of the service life of the relays.	54
		Unsuitable PID constant	Set appropriate PID constants using either of the following methods. • Execute AT (autotuning). • Set PID constants individually using manual settings.	62
		HS alarm operation fault	Use breeder resistance if the problem is due to leakage current. Also investigate the errors detected by the HS alarm function.	54
	Temperature is not rising	Specified operation is unsuitable for required control (default: Reverse operation)	Select either forward or reverse operation depending on the required control. Reverse operation is used for heating operations.	54
		Heater is burnt out or deteriorated.	Check whether heater burnout or deterioration have occurred. Also investigate the errors detected by the heater burnout alarm.	54
		Insufficient heater capacity	Check whether the heater's heating capacity is sufficient.	---
		Cooling system in operation.	Check whether a cooling system is operating.	---
		Peripheral devices have heat prevention device operat-ing.	Set the heating prevention temperature setting to a value higher than the set temperature of the Temperature Controller.	---

Note Refer to the E5CN/E5AN/E5EN/E5GN Digital Temperature Controller Communications Manual (Cat. No. H158) for details.

Timing	Status	Meaning	Countermeasures	Page
During operation (continued)	Output will not turn ON	Set to STOP (default: RUN)	Set the RUN/STOP mode to RUN. If STOP is lit on the display, control is stopped.	172
		Specified operation is unsuitable for required control (default: Reverse operation)	Select either forward or reverse operation depending on the required control. Reverse operation is used for heating operations.	54
		A high hysteresis is set for ON/OFF operation (default: 1.0°C)	Set a suitable value for the hysteresis.	60
	Temperature Controller will not operate	Set to STOP (default: RUN)	Set the RUN/STOP mode to RUN. If STOP is lit on the display, control is stopped.	172
	Temperature error is large Input error (S.err dis-play)	Thermometer has burnt out or short-circuited.	Check whether the thermometer has burnt out or short-circuited	---
		Thermometer lead wires and power lines are in the same conduit, causing noise from the power lines (generally, display values will be unstable).	Wire the lead wires and power lines in separate conduits, or wiring using a more direct path.	---
		Connection between the Temperature Controller and thermocouple is using copper wires.	Connect the thermocouple's lead wires directly, or connect a compensating conductor suitable for the thermocouple.	---
		Installation location of thermometer is unsuitable.	Check whether the location of the thermometer is suitable.	---
		Input shift is not set correctly (default: 0°C)	Set a suitable input shift. If input shift is not required, set the input shift value to 0.0.	89
	Keys will not operate	Setting change protect is ON.	Turn OFF setting change protect.	110
	Cannot shift levels	Operations limited due to protection.	Set the operation/adjustment protect, initial setting/communications protect, and setting change protect values as required.	110
After long service life	Control is unstable	Terminal screws may be loose.	Retighten terminal screws to a torque of 0.74 to 0.90 N·m (see note).	33
After long service life	Control is unstable	The internal components have reached the end of their service life.	The Temperature Controller's internal electrolytic capacitor depends on the ambient temperature, and load rate. The structural life depends on the ambient environment (shock, vibration). The life expectancy of the output relays varies greatly with the switching capacity and other switching conditions. Always use the output relays within their rated load and electrical life expectancy. If an output relay is used beyond its life expectancy, its contacts may become welded or burned. Replace the Temperature Controller and all other Temperature Controllers purchased in the same time period.	---

Note The tightening torque is 0.5N· m for the E5CN-U and 0.43 to 0.58N· m for the E5GN. The terminal torque is 0.5 to 0.6N· m for auxiliary output 2 on the E5GN.

Symptom: Cannot Communicate or a Communications Error Occurs

Meaning	Countermeasures
The communications wiring is not correct.	Correct the wiring.
The communications line has become dis- connected.	Connect the communications line securely and tighten the screws.
The communications cable is broken.	Replace the cable.
The communications cable is too long.	The total cable length is 500 m maximum for RS-485 and 15 m maximum for RS-232C communications. To extend the communications distance for RS-232C communications, use OMROM's Z3R Optical Interface.
The wrong communications cable has been used.	E5CN, E5EN, or E5AN: Use a shielded, AWG24 to AWG14 (cross-sec-tional area of 0.205 to 2.081 mm2) twisted-pair cable for the communica-tions cable. E5GN: Use a shielded, AWG24 to AWG18 (cross-sectional area of 0.205 to 0.823 mm2) twisted-pair cable for the communications cable.
More than the specified number of communi-cations devices are connected to the same communications path for RS-485 communi-cations.	When 1:N RS-485 communications are used, a maximum of 32 nodes (including the host node) can be connected.
An end node has not been set at each end of the communications line for RS-485 communi-cations.	Set or connect terminating resistance at each end of the line. If the E5CN, E5AN, E5EN, or E5GN is the end node, use 120-Ω (1/2-W) terminating resistance. The combined terminating resistance with the host device must be at least 54 Ω.
The specified power supply voltage is not being supplied to the Controller.	Supply the specified power supply voltage.
The specified power supply voltage is not being supplied to an Interface Converter (such as the K3SC).	Supply the specified power supply voltage.
The same baud rate and communications method are not being used by all of the Con-trolers, host devices, and other devices on the same communications line.	Set the same values for the baud rate, protocol, data length, stop bits, and parity on all nodes.
The unit number specified in the command frame is different from the unit number set by the Controller.	Use the same unit number.
The same unit number as the Controller is being used for another node on the same communications line for RS-485 communica-tions.	Set each unit number for only one node.
There is a mistake in programming the host device.	Use a line monitor to check the commands. Check operation using a sam-ple program.
The host device is detecting the absence of a response as an error before it receives the response from the Controller.	Shorten the send data wait time in the Controller or increase the response wait time in the host device.
The host device is detecting the absence of a response as an error after broadcasting a command (except for SYSWAY).	The Controller does not return responses for broadcast commands.
The host device sent another command before receiving a response from the Control-ler.	The response must always be read after sending a command (except for broadcast commands).
The host device sent the next command too soon after receiving a response from the Controller.	After receiving a response, wait at least 2 ms before sending the next command.
The communications line became unstable when Controller power was turned ON or interrupted, and the host device read the unstable status as data.	Initialize the reception buffer in the host device before sending the first command and after turning OFF the power to the Controller.
The communications data was corrupted from noise from the environment.	Try using a slower baud rate.Separate the communications cable from the source of noise.Use a shielded, twisted-pair cable for the communications cable.Use as short a communications cable as possible, and do not lay or loop extra cable.To prevent inductive noise, do not run the communications cable parallel to a power line.If noise countermeasures are difficult to implement, use an Optical Inter-face.

Note For details on errors, refer to E5CN/E5AN/E5EN/E5GN Digital Temperature Controllers Communications Manual Basic Type (Cat. No. H158).

Note (1) Initialized to input setting range upper and lower limits, or scaling upper and lower limits.

(2) Clamped by SP upper and lower limits.

(3) Initialized only when the input type is changed to analog input when RT turns ON. The defaults are as follows:

RT: OFF

Proportional band: 8.0

Integral time: 233

Derivative time: 40

(4) Initialization is performed as shown below according to the transfer output type setting. The initialization differs depending on the changed parameter and the output type setting.

SP: SP upper and lower limits

Ramp SP: SP upper and lower limits

PV: Input setting range upper and lower limits or scaling upper and lower limits

MV (Heating): 100.0/0.0

MV (Cooling): 100.0/0.0

(4-1) Initialized only when the transfer output type is set to SP, Ramp SP, or PV.
(4-2) Initialized only when the transfer output type is set to MV (Heating) or MV (Cooling).

(4-3) Initialized to the above default values regardless of the settings for changing the transfer output type.

(5) Initialized as follows according to the Standard or Heating/Cooling parameter setting.

MV Upper Limit: 105.0

MV Lower Limit: Standard -5.0, heating/cooling -105.0

(6) Initialized to control output (cooling) for heating and cooling control, according to the following.

(The defaults for standard control are the defaults in the parameter list.)

With control output 2: The Control Output 2 Assignment parameter is initialized to control output (cooling).

Without control output 2 and E5AN/EN: The Auxiliary Output 3 Assignment parameter is initialized to control output (cooling).

Without control output 2 and E5CN: The Auxiliary Output 2 Assignment parameter is initialized to control output (cooling).

E5GN: The Auxiliary Output 1 Assignment parameter is initialized to control output (cooling).

(7) When the program pattern is OFF, the Auxiliary Output 1 Assignment parameter is initialized to alarm output 1. When the program pattern is not OFF, the Auxiliary Output 1 Assignment parameter is initialized to program end output. The Auxiliary Output 1 Assignment parameter is not initialized for the E5GN, however, if it is set for heating/cooling control.

(8) If the Program Start parameter is assigned when the program pattern is changed to OFF, the Program Start parameter will be initialized to "not assigned."

(9) Initialized when temperature inputs are used and RT is changed. The defaults are as follows: Proportional band: 8.0

Integral time: 233

Derivative time: 40 when RT is OFF, and 40.0 when RT is ON.

(10) The proportional band, integral time, and derivative time are initialized as follows by RT and input type changes.

When RT is turned from ON to OFF by a change from temperature input to analog input.
When ON is turned to OFF or OFF is turned to ON by an RT change.

(11) Write to both so that the SP and the currently selected Multi-SP SP0 to SP3 match.
(12) Initialized event input assignments used for Multi-SP to NONE.
(13) Initialized to 0.8 when the temperature unit is ^ C , and to 1.4 when the temperature unit is ^ F .

Setting Levels Diagram

This diagram shows all of the setting levels. To move to the advanced function setting level and calibration level, you must enter passwords. Some parameters are not displayed depending on the protect level setting and the conditions of use.

Control stops when you move from the operation level to the initial setting level.

OMRON E5EN - Setting Levels Diagram - 1

Note (1) You can return to the operation level by executing a software reset.

(2) It is not possible to move to other levels from the calibration level by operating the keys on the front panel. It can be done only by first turning OFF the power.
(3) From the manual control level, key operations can be used to move to the operation level only.
(4) When the PF Setting parameter is set to A-M for a Controller with a PF Key (E5AN/EN).
(5) When the PF Setting parameter is set to PFDP for a Controller with a PF Key (E5AN/EN)
