Frequently Asked Questions - RE22T PCE Instruments

How do I change the set point during normal operation?

Press the SET button (the middle push-button) to enter set point change mode. Use the UP and DOWN buttons to adjust the value, then press SET again to confirm. The display will show the measured value normally after a few seconds.

What types of sensors can I connect to the RE22T?

The RE22T has a universal input supporting RTD (Pt100, Pt1000), thermocouples (types J, K, T, S, R, B, E, N, L), linear current (0-20 mA or 4-20 mA), and linear voltage (0-5 V or 0-10 V). Select the sensor type using the inPt parameter.

How do I set the controller to ON/OFF mode?

Set the Pb (proportional band) parameter to 0. Then adjust the hysteresis (Hy) parameter to your desired switching differential. The output action (heating or cooling) is set by the out parameter (r for reverse/heating, d for direct/cooling).

How do I perform auto-tuning for PID parameters?

Navigate to the At parameter in the menu. Press and hold the SET button for at least 2 seconds to start auto-tuning. The upper display will flash during the process. Auto-tuning can last up to 10 hours. After completion, the PID parameters are stored automatically.

What does error code 'H_Err' mean?

H_Err indicates an over-range or sensor break. Check that the correct sensor type is selected in inPt, that the input signal is within range, and that the sensor wiring is intact (no open circuit). For thermocouples, ensure the compensation is correct.

How do I restore factory settings?

While powering on the controller, press and hold the UP and DOWN buttons simultaneously until the display shows 'FAb'. Release the buttons; the controller will reset to manufacturer defaults.

Can I protect the controller settings with a password?

Yes, set the SEcu parameter to a non-zero value (0-9999) to enable password protection. Once set, the menu will require entering this code to modify parameters. The SEcu parameter itself becomes hidden after setting.

What is the soft-start function and how do I activate it?

Soft-start gradually ramps the set point to the target value, limiting the rate of temperature change. Set the SPEr parameter to the desired change rate (e.g., 10 per minute) and rPnP to the time unit (minute or hour). A value of 0 disables soft-start.

How do I manually control the output?

First, display the control signal by pressing the DOWN button (the display shows 'h' followed by the percentage). Then press and hold the DOWN button again to enter manual mode (the MAN LED blinks). Use UP and DOWN to adjust the output percentage from 0 to 100%. Press SET to exit manual mode.

What is the maximum load for the relay output?

The relay output (changeover contact) can handle 5 A at 250 V AC or 5 A at 30 V DC resistive load. For inductive loads, derating is required. Maximum power: 1250 VA (AC) or 150 W (DC).

1' APPLICATION

PCE-

The ^1 RE22 controller co-operates directly with resistance thermometers (RTD) and thermocouples (TC) or quantity converters into a standard signal.

It is destined for temperature control in plastics' food' glass' ceramics' dehydration industries and everywhere when it is necessary to stabilize temperature changes.

The measuring input is universal for resistance thermometers and thermocouple sensors or for linear standard signals.

The relay output with a make-brake configuration (with NOC or NCC contacts) allows to the direct control of low power objects.

The manual control and soft-start are also possible.

One can protect the controller against the undesirable change of parameters by means of a password:

The auto-tuning function permits to select the PID setting in order to a quick output signal adaptation to object parameters:

When connecting the supply' one must remember that an automatic cut-off should be installed near the device' easily accessible for the operator and suitably marked.

3'4' Installation recommendations

The "PULREZZ" controller fulfils requirements concerning the fastness against electromagnetic interference occurring in the industrial environment acc' to obligatory standards.

In order to obtain a full immunity of the controller against electromagnetic interference in an unknown environment interference level it is recommended to observe following principles:

- do not supply the controller from the network near devices generating high impulse interference and do not use common earthing circuits with them'

- apply network filters'

- apply metallic shields in the shape of tubes or braided screens to conduct supplying wires'

- wires supplying the measuring signal should be twisted in pairs' and for resistance thermometers in a 3-wire connection' twisted from wires with the same length' cross-section and resistance, and led in a shield as above'

• all screens should be one side earthed' and led the nearest possible to the controller'
• apply the general principle that wires leading different signals should be led the farthest possible between them (not less than 30 cm)' and their crossing executed at a right angle.

4' STARTING TO WORK

Fig 6 View of the controller frontal plate

After connecting to the power, the controller carries out the display test and displays the 'ε22 inscription' the program version, and next displays the measured value.

A character message can appear on the display' informing about abnormalities' (table 4).

The algorithm of ON-OFF control with a 2^ C hysteresis is set by the manufacturer.

Change of the set point

The way to change the set point during the normal work is shown on the fig. 7. The change limitation is set by SPL and SPH parameters.

The return to the normal working mode follows after the simultaneous pressure of and push buttons' or automatically' after

30 sec from the last push-button pressure

Some parameters can be invisible - it depends on the current controller configuration:

The access to parameters can be protected by a code. If the safety code is set (parameter SECU is higher than zero), one must give it. If the value will not be given or will be erroneous, the inscription ERR appears on displays' and the user will be only able to monitor parameter values:

5'2' Setting change

The change of parameter setting begins after pressing the push-button. By means of and push-buttons we make the choice of the setting and by the push-button we accept it.

6' INPUTS AND OUTPUTS OF THE CONTROLLER

6'1' Measuring input

The controller has one measuring input' which on can connect different types of sensors or standard signals to

The choice of the input signal is performed by the 'opt' parameter. For different types of inputs' depending on the option code, one must give additional parameters:

For the Pt100 resistance thermometer' one must choose the kind of connection. In a three-wire connection' the line resistance compensation goes on automatically

In a two-wire connection' one can give additionally the line resistance' for thermocouples' one must give the way of temperature compensation of cold ends - automatic or manual' and at manual compensation - the temperature of cold ends.

For linear inputs' one must give indications for the lower and upper threshold of the analog input. The position of the decimal point is an additional parameter, the parameter dP .

For temperature sensors' it defines whether the measured temperature and the set point temperature is to be shown with a place after the decimal point

For linear inputs' it defines the resolution which the measured value and values of some parameters are shown with

The correction of measured value indications is carried out by the 5x' F parameter

6'2' Output

The controller has one measuring input with a switch over contact. It is possible to select the ON-OFF control or proportional (PID) control at the output. For the proportional control, one must additionally set the pulse repetition period. The pulse repetition period is the time which expires between successive switches of the output during the proportional control. The length of the pulse repetition period must be chosen depending on dynamic properties of the object and suitably to the output device for quick-acting processes, it is recommended to apply SSR relays. The relay output is used to control contactors in slow-acting processes.

The use of a high pulse repetition period to control quick-acting processes can give unwanted effects in the shape of oscillations. Theoretically' smaller the pulse repetition period better the control is but for the relay output it should be as high as possible in order to extend the relay life:

Recommendations concerning the pulse repetition period Table 3

electromagnetic recommended >20 s 2 A/230 V a·c·relay min·10 s or contactor
min·5 s 1 A/230 V a·c·
transistor output 1···	3 s Semi-conductor	relay (SSR)

7° CONTROL

7'1' ON-OFF control

To select the ON-OFF control' one must set the parameter p_b = 0 . Next' set the hysteresis value - y . The action of the output on heating (fig. 10') is set by the parameter out = 'n' and on cooling by the parameter out = d' .

Fig 10' Operation way of the heating type output

7'2' PID control

The choice of PID control' or also PI' PD or P control' consists on a suitable setting of parameter values - proportional band (Pb)' integrating element (t') and differentiating element(t d). The switching of the giving element off consists on setting the parameter on zero. The operation way of the heating type output is chosen by setting the parameter out! = 'ou' and the cooling type by setting the parameter out=d'. The successive parameter to set is the pulse repetition period of the output (t0).

8' ADDITIONAL FUNCTIONS

8'1' Display of the control signal

After pressing the push-button' the value of the control signal (0…100%) appears on the display. On the first digit' the mark h is displayed. The return to the normal operation follows after the simultaneous pressure of and push-buttons.

8'2' Manual control

The manual control gives the possibility' among other things' to identify and test the object or control it after the sensor damage.

The entry into the manual control mode follows after holding down the push-button when displaying the control signal. The manual

control is signaled by the diode pulsation' marked as MAN. The controller breaks the automatic control and begins the manual control of the output. The value of the control signal is displayed on the lower display' preceded by the symbol.

and push-buttons serve to change the control signal'

which is displayed on the lower display. The exit to the normal working mode follows after the simultaneous pressure of and

push-buttons

After setting the ON-OFF control on the output 1 (parameter PB = 0)' one can set the control signal on 0% or 100% of power' however when the PB parameter is greater than zero' the control signal can be set on any value from the 0…100% range

8'3' Controller reaction (response) after the sensor damage

It is possible to configure the output state after the sensor damage. - at output configuration for proportional control(PB>0) the control signal value is defined by the FR' L parameter - at output configuration for the ON-OFF control' the output will be disabled - at output operation as heating' or enabled - at output operation as cooling.

8'4' Rate of the set point change - soft-start

The limitation of the temperature accretion rate is performed through the gradually change of the set point. This function is activated after switching the controller supply on and during the change of the set point. This function allows to reach in a gentle way the achievement from the current temperature to the set point. One should write the accretion value to the SPR parameter and the time unit to the RP parameter.

An accretion value equal to zero means' that the soft-start is disabled

8'5' Manufacturer's settings

One can restore manufacturer's settings during the supply switching on by holding down and push buttons till the moment when the inscription FAB appears on the upper display

9' SELECTION OF PID PARAMETER SETTINGS

9'1' Auto-tuning

The controller has the function of the automatic PID setting choice. These settings ensure the optimal control in the majority of cases.

To start the auto-tuning' one must transit to the tune parameter (acc' to the fig'8) and hold down the push-button during

at least 2 sec. If the proportional band is equal zero or the REFO parameter is set on OFF' there will not be possible to start the auto-tuning.

The flickering upper display informs about the activity of the auto-tuning function. The duration of the auto-tuning function depends on object dynamic properties and can last maximally 10 hours. During the auto-tuning' or directly after' overshoots can occur and therefore one must set a smaller set point' if it is possible.

The auto-tuning is composed of following stages:

• switching the control signal off and stabilization of the object temperature (from 2 minutes till 3 hours)
• switching the control signal (100%) on' and determination of the object characteristic (maximally 10 hours)'
• calculation of PID settings and their storage in the non-volatile memory
• switching the PID control on with new settings

The auto-tuning process may not start or be interrupted without the PID control if.

• the set point is too near to the measured value' i'e' the control deviation is smaller than 6.25% of the range'
• the time of the preliminary object stabilization or the admissible auto-tuning duration time will be overrun'
• a controller supply decay will occur

- the push-button has been pressed'

- calculated parameter values are beyond the range. In such cases' the control with previous user's settings will start

9'2' Manual selection of PID parameter settings Method of response to a unitary jump

Fig 11. Selection of settings by the method of response to a unitary jump

One must read out the delay time To and the maximal temperature accretion rate from the object characteristic presenting the controlled value in the function of time' from the dependence:

$$ V _ {\max} = \frac {\Delta P V _ {\max}}{\Delta t} $$

Calculate PID settings acc to following formulas:

$$ P b = 1 \cdot 1 V ^ {\max} T _ {0} - \text { proportional band } $$

$$ t ^ {i} = 2 \cdot 4 T ^ {0 -} \text { integration time constant } $$

$$ t ^ {d} = 0. 4 T ^ {0} \quad - d i f f e r e n t i a t i o n t i m e c o n s t a n t $$

Oscillation method around the set point

Set the ON-OFF control with a minimal hysteresis' Set the set point on a normal work level (or on a lower one' if overshoots would cause damages) and normal load conditions:

Fig 12 Selection of settings by the oscillation method Calculate controller settings acc to given formulas:

$$ \begin{array}{l} P b = P \ \mathrm{ti} = \mathrm{T} \ \mathrm{td} = 0. 2 5 * \mathrm{T} \ \end{array} $$

Correction of PID settings

Since PID parameters interact between them' one must introduce changes only of one parameter

The best is to choose parameters changing the value into a twice greater or twice smaller one:

During changes' one should be guided by following principles:

a) Slow jump answer:

• decrease the proportional band
• decrease the integration and differentiation time

b) Over-regulations:

• increase the proportional band'
• increase the differentiation time

c) Oscillations:

• increase the proportional band'
• increase the integration time'
• decrease the differentiation time

d) Instability:

- increase the integration time
