10.2 Output configuration

This chapter describes the options for the output signals at OUT1 and OUT2.

10.2.1 Switching signal for limit value monitoring

A switching signal can be output for process value monitoring. OUTx changes its switching state when the set switching limits are exceeded or not reached. You can choose between hysteresis and window function.

Hysteresis function:

1: Process value

t: Time

SP: Set point

rP: Reset point

HY: Hysteresis

Hno: Hysteresis function NO (normally open)

Hnc: Hysteresis function NC (normally closed)

Fig. 8: Hysteresis function

When the hysteresis function is set, the set point SP and the reset point rP are set. The rP value must be lower than the SP value. The difference between SP and rP is at least 0.5 % of the final value of the measuring range (= hysteresis). If only the set point is changed, the reset point is changed automatically; the difference remains constant.

Window function:

1: Process value

t: Time

FH: Upper limit value

FL: Lower limit value

HY: Hysteresis

FE: Window area

Fno: Window function NO (normally open)

Fnc: Window function NC (normally closed)

Fig. 9: Window function

When set to the window function, the window high FH and the window low FL are set. The difference between FH and FL is at least 0.5% of the final value of the measuring range. FH and FL have a fixed hysteresis of 0.25% of the final value of the measuring range. This helps keep the switching status of the output stable if the flow rate varies slightly.

Parameters to be set:

oux= Hno, Hnc, Fno, Fnc; SPx; rPx; FHx; FLx

10.2.2 Switching signal Diagnosis

The unit features an integrated diagnostic function. When using the diagnostic function, the output is used exclusively for diagnostic message output, which it indicates by a switched signal.

The switching output is switched on in normal operation (normally closed). If the device detects a diagnostic case, the output will be switched off.

Diagnostic cases include:

• Reversal of the direction of flow ➕ 23
  • Low signal quality / no signal ➞ 23

10.2.2.1 Switching signal for flow direction

A flow direction change can be monitored by providing a switching signal.

The output is switched on until the flow rate falls below the set minimum flow rate in negative flow direction (- LFC)(1).

Then the following applies:

• The output switches ON when + LFC is exceeded (2).
- The output switches OFF when - LFC is not reached (3).

LFC = Low flow cut-off → Low flow cut-off → 32.

Fig. 10: Monitoring of the flow direction by switching signals

+Q: Flow in positive flow direction
-Q: Flow in negative flow direction
+LFC: Minimum flow in positive flow direction
-LFC: Minimum flow in negative flow direction

An arrow with the text “flow direction” on the device indicates the positive flow direction. The direction of the flow measurement can be reversed using the parameter Fdir.

→ Flow direction → 32.

Parameters to be set:

oux = dOU ; dFUx = direction of flow

10.2.2.2 Switching signal for signal quality

The unit can provide a switching signal when the signal quality deviates from normal operation.

The signal quality of the sensor can be affected by irregularities in the medium (e.g. strong turbulences, air bubbles, particles or build-up).

The unit detects the signal quality in three stages:

Signal quality	Explanation	Switching output
Normal	The device operates without restrictions (normal operation).	On
Low	The signal quality is disturbed, but the device is still working within its specifications.	OFF
No signal	No medium is present or no signal can be created.	OFF

Parameters to be set:

oux = dOU ; dFUx = signal quality

10.2.3 Consumed quantity monitoring (totaliser function)

The unit has 3 internal quantity meters (totalisers Vol.1, Vol.2 and Vol. L). The totalisers continuously sum up the consumed quantity and provide this process value via the IO-Link interface.

Totaliser	Process value	Read access via IO-Link
Vol.1	Consumed quantity 1(This value is used for consumed quantity monitoring by switching or pulse signals)	Cyclic
Vol.2	Consumed quantity 2	Acyclic
Vol. L	Consumed quantity over the whole lifetime (lifetime totaliser)	Acyclic

• The totalisers Vol.1 and Vol.2 can be reset. Totaliser Vol. L cannot be reset.
  → Totaliser reset → 34.
• The totalisers Vol.1 and Vol.2 take account of the following parameter settings when totalising the consumed quantity:
  → Flow direction → 32.
  → Counting method of the totalisers → 34.
  → Low flow cut-off → 32.

- The Life Time Totalisator Vol. L totals all flow quantities regardless of the flow direction and counting method.

- When the detection range (cr. OL) is exceeded, the totalisers use the last valid flow rate value (measuring range end value) and continue counting with this value.

- In addition to the current consumed quantity, the value before the last reset is saved. This value and the time since the last reset can also be displayed.

Read totaliser values → 36

The totaliser saves the totalled consumed quantity at regular intervals. After a power failure this value is available as the current meter reading. If a time-controlled reset is set, the elapsed time of the set reset interval is also saved. This means that the possible data loss can amount to one minute.

• The accuracy of the consumed quantity measurement depends on the accuracy of the flow measurement.
• A switching signal or pulse signals can be provided for consumed quantity monitoring:

Switching signal totaliser ➕ 25

Switching signal totaliser ➕ 25

→ Pulse signal totaliser → 25

OUT1 and OUT2 cannot be used simultaneously for the consumed quantity monitoring.

10.2.3.1 Switching signal totaliser

A switching signal can be provided for consumed quantity monitoring.

When totaliser Vol.1 has totalled the flow quantity (pulse value) set under ImPS, the output provides a switching signal.

The flow direction is taken into account when totalling the flow quantity ➞ 34.

The output remains switched until a totaliser reset is carried out. When the totaliser has been reset, metering starts again.

The totaliser is reset automatically or manually.

The conditions for the totaliser reset and the switching signal can be set via the parameter rTo:

- rTo = OFF:

• The totaliser is only reset with a manual reset or after overflow.
• The output is switched when the totaliser has reached the flow quantity ImPS.

• rTo = ...h / d / w (hours / days / weeks):

• The totaliser is automatically reset after the set time.
• The output is only switched when the totaliser reaches the flow quantity ImPS by the set time.

The totalisers can be reset manually at any time via the rTox parameter. Totaliser Vol.1 can additionally be reset via an external signal at pin 2.

→ Totaliser reset → 34

Parameters to be set:

oux = ImP ; ImPSx ; ImPRx = no

10.2.3.2 Pulse signal totaliser

Pulse signals can be provided for consumed quantity monitoring.

Pulse signals are not available via the IO-Link interface.

The output provides a pulse signal each time totaliser Vol.1 has totalled the flow quantity (pulse value) set under ImPS.

The flow direction is taken into account when totalling the flow quantity → 34.

The pulse signal consists of a short switching on and off of the output.

Parameters to be set:

oux = ImP ; ImPSx ; ImPRx = yes

10.2.4 Analogue signal

The device provides an analogue signal proportional to the process value.

Within the measuring range the analogue signal is between 4...20 mA.

The measuring range can be scaled between -100% and 100% of the final value of the measuring range.

A negative flow value means flow against the flow direction set under [Fdir] ➕ 32.

• ASP2 determines at which measured value the output signal is 4 mA.
  • AEP2 determines at which measured value the output signal is 20 mA.

Minimum distance between ASP2 and AEP2 = 20 % of the final value of the measuring range.

If the measured value is outside the measuring range or in the event of an internal error, the current signal indicated in the following figure is provided.

Fig. 11: Characteristic of the analogue output according to IEC 60947-5-7.
*For devices with nominal diameters DN15...50, the MEW is between 125...130°C (257...266°F), the temperature limits for OL and cr. OL shift accordingly.

A: Analogue signal MAW: Initial value of the measuring range

B: Process value MEW: Final value of the measuring range

1: Detection zone ASP: Analogue start point

2: Display range AEP: Analogue end point

3: Measuring range UL: Below the display range

4: Scaled measuring range cr. UL: Below the detection zone

Q: Flow OL: Above the display range

T: Temperature cr. OL: Above the detection zone

The analogue signal in case of a fault can be set via the parameter FOU: Error behaviour of the outputs ➕ 29.

Parameters to be set:

ou2 = 1 / 4...20 mA, ASP2; AEP2

10.2.5 Frequency signal

The device provides a frequency signal proportional to the process value.

The frequency signal is adjustable:

- FrP1 defines the frequency signal in Hz that is provided when the upper measured value is reached.

Setting range: 1 Hz...10 kHz.

The measuring range is scalable:

• FSP1 defines the lower measured value from which a frequency signal is provided.
  • FEP1 defines the upper measured value at which the output signal has the frequency set under FrP1.

FSP1 is only available for temperature measurement. Minimum difference between FSP1 and FEP1 = 20 % of the final value of the measuring range.

If the measured value is outside the measuring range or in the event of an internal error, the frequency signal indicated in the following figure is provided.

Frequency signal for flow:

10.2.6 Error behaviour of the outputs

The response of the OUTx output in case of a fault can be set via the parameter FOUx. Depending on the selected output function, the following signals are provided in case of a fault:

- Switching signal:

FOUx	Process values SELx	Output signal	Explanation
On	All process values	The output switches ON in case of a fault.	As soon as a defective process value is present, the device sets all process values to invalid.
OFF	All process values	The output switches OFF in case of a fault.
OU	Flow	The output switches OFF in case of a fault.	If the process value “Flow” is defective, the device continues to provide the process value “Temperature”.
	Temperature	The output switches ON in case of a fault.	If the process value “Temperature” is defective, the device continues to provide the process value “Flow”.

- Analogue signal:

FOUx	Process values SELx	Output signal	Explanation
On	All process values	In case of an error the output goes to 21.5 mA.	As soon as a defective process value is present, the unit sets all process values to invalid.
OFF	All process values	In case of an error the output goes to 3.5 mA.
OU	Flow	In case of an error the output goes to 3.5 mA.	If the process value “Flow” is defective, the unit continues to provide the process value “Temperature”.
	Temperature	In case of an error the output goes to 21.5 mA.	If the process value “Temperature” is defective, the unit continues to provide the process value “Flow”.

• Frequency signal:

FOUx	Process values SELx	Output signal	Explanation
On	All process values	In case of an error the output goes to 130% of FrPx.	As soon as a defective process value is present, the device sets all process values to invalid.
OFF	All process values	In case of an error the output goes to 0 Hz.
OU	Flow	In case of an error the output goes to 0 Hz.	If the process value “Flow” is defective, the device continues to provide the process value “Temperature”.
	Temperature	In case of an error the output goes to 130% of FrPx.	If the process value “Temperature” is defective, the device continues to provide the process value “Flow”.

The parameter FOU has no influence on the pulse signal, the diagnostic signals for flow direction and signal quality and the IO-Link process data transmission.

10.2.7 Output off

The output signal can be switched off via the parameter oux = OFF . The output then goes to high impedance.

Communication via the IO-Link interface on OUT1 remains active.

10.3 Application configuration

The chapter describes the setting options for adaptation to your specific application.

10.3.1 Standard unit of measurement

It is possible to set a unit of measurement for each process value, on which further parameter settings will be based.

Selectable values:

- Flow uni. F:

• SUHxx0: I/min; I/h; m³/h; m/s.
  – SUHxx1: l/min; l/h; m³/h ; m/s; gal/min; gal/h; ft/s; oz/min.

• Temperature uni. T:

• SUHxx0: °C.
• SUHxx1: °C; °F.

10.3.2 Process value for OUT1 and OUT2

The process value to be output via OUTx can be selected using the parameter SELx.

Selectable values:

• FLOW: Flow
  • TEMP: Temperature

10.3.3 Damping

The set damping constant stabilises the output signals. Abrupt changes in the physical process values are smoothed out.

This concerns the outputs and the process value transmission via the IO-Link interface.

The damping constant dAP is used to set after how many seconds the output signal reaches 63 % of the final value if the measured value changes suddenly.

The damping constant is added to the response time of the sensor (→ Technical data).

The UL and OL signals are defined under consideration of the damping time.

Measured value damping only has an effect on the process value flow.

10.3.4 Output polarity

The output polarity is set via the parameter P-n.

The setting affects both switching outputs.

• PnP: The switching output is positive switching.
• nPn: The switching output is negative switching.

10.3.5 Low flow cut-off

Low flow quantities can be ignored using the parameter LFC (Low flow cut-off). Flow below the LFC value is evaluated by the sensor as standstill (Q = 0).

The LFC value influences:

• The switching signal for flow
• the analogue signal for flow
• The frequency signal for flow
• the consumed quantity monitoring (switching or pulse signal for flow)
- The totalisation of the consumed quantity by the totaliser.
• the memory values for minimum and maximum flow

Fig. 14: Low flow cut-off

+LFC: Minimum flow in positive flow direction

-LFC: Minimum flow in negative flow direction

1: Flow which is evaluated as standstill

10.3.6 Medium

The sensor provides various characteristic curves for the respective media. They can be selected via the MEdl parameter.

Selectable values:

• H2O: Water
• OIL46: High-viscosity oils (viscosity: 30...68 mm ² /s at 40 °C / 30...68 cSt at 104 °F)

10.3.7 Flow direction

The positive flow direction can be defined by the user. This setting affects the following functions:

→ Consumed quantity monitoring (totaliser function) → 24
Switching signal for flow direction 23
→ Analogue signal → 25

An arrow with the text “flow direction” on the device indicates the positive flow direction (factory setting). The direction of the flow rate measurement can be reversed using the parameter Fdir:

Fdir	Direction of flow
+	Flow direction in case of factory setting
-	Flow direction contrary to the factory setting

10.3.8 Calibration

The calibration factor CGA is used to adjust the temperature-viscosity compensation of the sensor to the characteristics of the medium used. The calibration factor influences the slope of the measurement characteristic of the flow measurement.

The slope modification of the measurement characteristic is indicated in percent. The factory setting is CGA = 100%. After a change the calibration can be reset to factory setting.

Fig. 15: calibration of the measurement characteristic

1: calibration factor CGA

2: process value

MW: measured value

V0: measurement characteristic at factory setting

V1: measurement characteristic 1 after calibration

V2: measurement characteristic 2 after calibration

10.3.9 Zero calibration

If there is a systematic deviation between the measured value and the actual process value, this measurement inaccuracy can be corrected using the correction factor cOF.

The unit for coF corresponds to the set standard unit of measurement for flow rate.

The internal zero point is shifted by the set value.

Fig. 16: Zero-point calibration (calibration offset)

t: Time

MEW: Final value of the measuring range

V0: Curve of measured values at factory setting

V1: Curve of measured values after offset

V2: Curve of measured values after offset

Setting range:

coF - FLOW = - 10 % ... +10 %

The parameter is reset to the factory setting both via an application reset and a back-to-box reset.

10.3.10 Totaliser reset

The totalisers Vol.1 and Vol.2 can be reset in different ways:

Type of reset		Parameter
1.	Manual reset	Command Reset Totaliser x
2.	Time-controlled reset	Reset Totaliser x =... h (hours)... d (days)... w (weeks)
3.	Reset via external signal	ou2 = In. DDln2:+EDG = reset for rising edge-EDG = reset for falling edgeHIGH = reset for high signalLOW = reset for low signal
4.	Reset via overflow(maximum display range is reached)	Reset Totaliser x = OFF

Totaliser Vol. L cannot be reset.

If totaliser Vol.1 is reset in one of the above ways, the output is also reset in the case of consumed quantity monitoring.

→ Switching signal totaliser → 25.

10.3.11 Counting method of the totalisers

The totalisers Vol.1 and Vol.2 take account of the flow direction when totalising the consumed quantity. The following counting methods can be defined via the parameter FProx:

FProx	Counting method
0+	Negative volumetric flow values (against the marked flow direction) are not taken into account for totalling.
-0	Positive volumetric flow values (corresponding to the marked flow direction) are not taken into account for totalling.
-+	Negative flow values are subtracted from the consumed quantity.
++	All volumetric flow values are totalled irrespective of the volumetric flow direction.

Tab. 2: Counting method of the totalisers

The counting method of Vol. L cannot be set. The lifetime totaliser totals all volumetric flow quantities irrespective of the flow direction.

The counting method affects the output signals for consumed quantity monitoring.

→ Consumed quantity monitoring (totaliser function) → 24.

Fig. 17: Taking into account the flow direction when totalling the consumed quantity

+Q: Flow quantity in positive direction

-Q: Flow quantity in negative direction

V: Flow quantity absolute (= sum of negative and positive flow)

1: Flow changes to negative direction

2: Flow changes to positive direction

3: Flow taken into account for totalisation

When the direction of flow is changed, the minimum flow quantity LFC is taken into account.

Low flow cut-off 32.

10.3.12 Reset the unit

The unit can be reset in 2 ways:

• APPL (application reset): reset of the parameter settings. The following is reset:

– All changed application-specific parameters

If IO-Link data storage is activated, this triggers a parameter update in the master. This writes the parameters configured in the master to the device again. An application reset may therefore be ineffective.

- BtB (Back to Box): reset to factory settings. The following is reset:

– All changed application-specific parameters
- All writeable unit identification parameters such as Application Specific Tag, Function Tag or Location Tag.
– Diagnostic parameters, status parameters, events.

After the Back to Box reset, the sensor suspends communication and measurement operation until the voltage is interrupted. The IO-Link data storage is not triggered.

We recommend documenting your own settings in the chapter Factory setting before carrying out a reset.

10.4 Diagnostic functions

The device offers a range of diagnostic functions.

Diagnostic messages can be provided via an output signal:

Switching signal Diagnosis → 23.

In addition, the diagnostic information described below is available via the IO-Link interface.

10.4.1 Read totaliser values

For the totalisers, the following values can be read at any time via the IO-Link interface:

Totaliser values Vol.1 and Vol.2

• Current flow quantity (= consumed quantity since the last totaliser reset)
  • Value before the last totaliser reset
  • Time since the last totaliser reset

Lifetime totaliser (for the entire operating time)

• Flow quantity in preferred direction (= positive direction of flow)
• Flow quantity in non-preferred direction (= negative direction of flow)
  → Flow direction → 32

10.4.2 Memory

The unit stores the maximum and minimum measured process values.

The current value can be read via the IO-Link interface.

Selectable values:

• Lo. F: Minimum value memory for volumetric flow
• Hi. F: Maximum value memory for volumetric flow
• Lo. T: Minimum value memory for temperature
• Hi. T: Maximum value memory for temperature

It makes sense to delete the memories as soon as the unit operates under normal operating conditions for the first time.

10.4.3 Operating hours counter

The operating hours since the first set-up are stored by the unit.

The current value can be read via the IO-Link interface.

The counter cannot be reset.

10.4.4 Internal temperature

The sensor measures the internal temperature.

The current value can be read via the IO-Link interface.

10.4.5 Signal quality

The signal quality of the sensor can be affected by irregularities in the medium (e.g. strong turbulences, air bubbles, particles or build-up).

The unit detects the signal quality in three stages:

Signal quality	Explanation
Normal	The unit operates without restrictions (normal operation).
Low	The signal quality is disturbed, but the unit is still working within its specifications.
No signal	No medium is present or no signal can be created.

The current value can be read via the IO-Link interface.

In addition, the signal quality can be indicated via a switching signal.

Switching signal for signal quality ➕ 23

10.5 Service functions

10.5.1 Device information

Unalterable device information is stored on the unit. This includes:

• Product name
• Product family
• Manufacturer
• Manufacturer ID
• Device ID
• Serial number
  • Hardware / firmware revision
• Description

In addition, further freely definable tags with a maximum length of 32 characters can be assigned to the unit via the IO-Link interface using suitable parameter setting software. This includes:

• application-specific tag
• function tag
• location tag

10.5.2 Simulation

With this function, process values are simulated and their signal path is checked.

Process values that lead to an error message or warning can be simulated (e.g. OL).

When the simulation is started, the values of the totaliser are frozen and the simulated totaliser is set to 0. The simulated flow value then has an effect on the simulated totaliser. When the simulation is ended, the initial totaliser values are restored.

During the simulation:

• The simulation has no effect on the current process values. The outputs operate as previously set.
• The original totaliser value remains saved without any changes even if there is a real flow.
• No error messages of the current application are available. They are suppressed by the simulation.

The following values can be simulated:

• process values for flow and temperature
- process values outside the measuring range (cr. UL, UL, OL, cr. OL)

Parameters to be set:

S. Tim; S. FLW; S. TMP

11 Operation

After power on and expiry of the power-on delay time, the unit is in the normal operating mode. It carries out its measurement and evaluation functions and generates output signals according to the set parameters.

12 Troubleshooting

The device has many self-diagnostic options. It monitors itself automatically during operation.

Warning and error messages are output as an event via the IO-Link interface.

The status signals are classified according to NAMUR recommendation NE107.

If the measured temperature value fails, the process value for flow rate is still available.

Additional diagnostic functions are available via IO-Link ➕ IO-Link interface description at documentation.ifm.com.
