10.3 Output configuration
10.3.1 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]. ( FlowÒ
direction 45)/
[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.
For measured values outside the display range or in case of an error, messages are displayed (cr.UL,
UL, OL, cr.OL, Err).
The analogue signal in case of a fault can be set via the parameter [FOU] ( Error behaviour ofÒ
the analogue output 43)/.
The analogue signal can be stabilised by setting the damping time [dAP] .

10.3.2 Switching signal diagnostics
The device features an integrated diagnostic function. When the diagnostic function is used, a
switching signal is provided via the hardware output.
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 flow direction ( Switching signal for flow direction 35)Ò/
no medium detected ( Switching signal for fluid detection 36)Ò/
10.3.2.1 Switching signal for flow direction
A flow direction change can be monitored by providing a switching signal.
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].
See .
Flow direction ( 45)Ò/
The flow direction that is currently indicated as positive can be viewed on the display (Ò

The output is switched on until the volumetric flow falls below the set minimum volumetric flow quantity
in negative flow direction (-LFC)(1).
Then the following applies:
The output switches ON when volumetric flow is above +LFC (2).
The output switches OFF when volumetric flow is below -LFC (3).

Pulse signals can be provided for consumed quantity monitoring.
Every time the consumed quantity (pulse value) set under [ImPS] has been reached, the output
provides a pulse signal.
The pulse signal consists of a short switching on and off of the output.
The pulse width depends on the pulse value and the flow speed: The lower the pulse value and the
higher the flow speed, the greater the pulse width. This applies up to a pulse width of 2s. Beyond this,
it remains at 2s.

10.3.4 Digital switching signal
The device provides digital switching signals via switching signal channels (SSC = Switching Signal
Channel).
The device has 2 digital switching signal channels SSCx.1 and SSCx.2 for each process value:
SSC1.1 and SSC1.2 = switching signal channels for consumed quantity (totaliser)
SSC2.1 and SSC2.2 = switching signal channels for flow
SSC3.1 and SSC3.2 = switching signal channels for temperature
SSC4.1 and SSC4.2 = switching signal channels for conductivity
Explanation of the numbering of the switching signal channels SSCx.y:
x = process value; y = switching signal channel
The switching signal channels can only be evaluated via the IO-Link interface.
The parameters for each switching signal channel can be set individually.
The switch point mode, switch points and the switch point logic are set when the switching signal
channel parameters are set.
The parameters for switching signal channels can only be set via the IO-Link interface.
Switch point mode
You can choose between the following switch point modes according to the IO-Link smart sensor
profile ‒ Function Class “Object Detection”:
• [Deactivated]
[Single Point Mode]
[Two Point Mode]
[Window Mode]
The switching signal channel changes to the active state depending on the process data value (PDV).
The active state is above the switch point in [Single Point Mode] and [Two Point Mode] and within the
window section in [Window Mode].
Switch point logic
By setting the switch point logic [High active] or [Low active], you can specify which value the
switching signal channel has in the active state:
[High active]: The switching signal channel is “high” in the active state (= ON = normally open = 1)
[Low active]: The switching signal channel is “low” in the active state (= OFF = normally closed = 0)
SMFxxx Magnetic-inductive flow meter
40
The following figures show the status of the switching signal channels depending on the switch point
mode, switch point logic and process data value (PDV).
Deactivated
If the [Deactivated] switch point mode is set for a switching signal channel, then the switching signal
channel will permanently have the following value regardless of the process value:
For switch point logic [High active]: permanently “low”.
For switch point logic [Low active]: permanently “high”.

switch point is the reset point. In the example shown, SP1 is the switch point and SP2 is the reset
point.
When teaching, the switch point is set directly to the taught process value. The following applies:

Window mode
Two switch points (SP1) and (SP2) are manually set or taught.
The two switch points define a window area.
The position of the switch points is freely selectable: SP1 can be below or above SP2. The lower
switch point is the lower limit value, the higher switch point is the upper limit value of the window area.
When teaching, the switch point is set directly to the taught process value. The following applies:
[TeachSP1] sets SP1, [TeachSP2] sets SP2.
When the process data value enters the window area, the status of the switching signal channel
changes immediately when the switch points are exceeded/not reached.
If the process data value leaves the window area, the status of the switching signal channel changes
when the switch point plus hysteresis (SP1+H or SP2-H) is exceeded/not reached.

If the process value “Temperature” is defective, the device
continues to provide the other process values.
COND In case of an error the output goes to
3.5mA.
If the process value “Conductivity” is defective, the device
continues to provide the other process values.
The parameter [FOU] has no influence on the pulse signal, the diagnostic switching signal and
the IO-Link process data transmission.

uSelect [FOU2] and set the error behaviour for output OUT2.
10.4.4 Damping
The set damping constant stabilises the output signals. Abrupt changes in the physical process values
are smoothed out.
This concerns the switching outputs, the display and the process value transmission via the IO-Link
interface.
The damping constant is added to the response time of the sensor ( Technical data).Ò
The UL and OL signals are defined under consideration of the damping time.
Measured value damping only has an effect on the measured variable flow.

uSelect [dAP.F] and set the damping time in seconds (τ value 63%).
10.4.5 Low flow cut-off
With the low flow cut-off [LFC] function it is possible to suppress low consumed quantities. Flow below
the LFC value is evaluated by the sensor as standstill (Q = 0).
Magnetic-inductive flow meter SMFxxx
45
The LFC value influences:
the process value for flow shown on the display
the digital switching signal for flow
the analogue signal for flow
the consumed quantity monitoring (switching or pulse signal for flow)
the memory values for minimum and maximum flow
The accuracy indicated in the data sheet applies to the factory-set LFC value. If a lower LFC
value is set, the accuracy of the sensor will decrease.

10.4.7 Flow direction
The positive flow direction can be defined by the user. This setting affects the following functions:
Consumed quantity monitoring
Flow direction monitoring via switching signal
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
uUse the supplied label to mark the changed flow direction (new positive flow direction) on the
device.
The flow direction that is currently indicated as positive can be viewed on the display (Ò

10.4.8 Zero calibration
The combination of display unit (converter) and measuring circuit can lead to measurement
inaccuracies, particularly depending on the respective ambient conditions.
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.x].
[coF.F] = correction factor for measuring flow
[coF.C] = correction factor for measuring conductivity
The unit of measurement for [coF.F] and [coF.C] is the set standard unit of measurement for the
process values flow and conductivity .

to the characteristics of the medium used. The calibration factor influences the gradient of the flow
measurement characteristic.
[CGA.F] = calibration factor for measuring flow

10.4.10 Influence of the medium on the temperature
The conductivity depends on the temperature. When the temperature increases, the conductivity
changes. This temperature influence depends on the respective medium and can be compensated by
the unit if the temperature coefficient (tempco) of the medium is known. The temperature
compensation is set via the parameter [T.Cmp]. Then the temperature-compensated conductivity
value corresponds to the conductivity at standard temperature (25 °C; factory setting of the parameter
[rEF.T]).
For medium that is not changed the same tempco value has to be set for all sensors (unit-
independent characteristic value). There is no further dependence on the measuring principle,
the lot or the manufacturer of the sensors.
If the temperature coefficient of the medium is not known, it can be determined.
See: Determination of the temperature coefficient tempco ( 48)Ò/
In an IO-Link environment, existing tempcos of the media can be stored as recipe in the
controller so that the accuracy of the values to be detected is improved.
10.4.10.1 Determination of the temperature coefficient tempco
1. Set the parameters [T.Cmp] and [dAP] to zero: [T.Cmp] = [0], [dAP] = [0].
uWrite the changed values to the sensor.
1. Adjust the medium to 25 °C, for example, and take down
the value of the conductivity after 2 min.
2. Heat up the medium to 45°C, for example, and take down
the value of the conductivity after 2min.
Example of values taken down:
Medium at 25°C = 500 µS/cm; medium at 45°C = 800 µS/cm
Temperature change = 20 K
1. Calculate the change of the conductivity in percent.
The conductivity has increased by 300µS/cm.
The percentage change is 300/500 = 60%.
2. Calculate the temperature coefficient tempco: The tempco is calculated from the change in percent
and the temperature change: Tk = 60 % / 20 K = 3 % / K
3. The calculated tempco can now be adopted into the parameter [T.Cmp].
Example: [T.Cmp] = [3]. If necessary, set the damping (parameter [dAP]) again.
uWrite values to the sensor.
10.4.10.2 Parameter setting via the device keys: Temperature compensation
uGo to menu [Settings] > [CFG] > [CAL].
uSelect [T.Cmp] and set the temperature coefficient of the medium.
uSelect [rEF.T] and enter the standard temperature.

10.4.11 Date/time
Setting the date and time serves to provide events and measurements with a time stamp.
For this, the date and time must be set during set-up. When setting the time, wither a 12hr or 24hr
format can be chosen. If the time is not set, the clock will start from an initial value (2024/01/01).
The device contains an internal energy storage unit so that, in the event of a power failure, the
settings are saved for a transitional period. If the power supply is interrupted for too long, the
display will show the symbol and the message that the date and time are no longer set.

10.4.14 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]:
SMFxxx Magnetic-inductive flow meter
52
[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 ac-
count for totalling.
-+ Negative flow values are subtracted from the consumed quantity.
++ All volumetric flow values are totalled irrespective of the volumetric flow direction.
Tab.12: 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.
Fig.30: taking account of the volumetric flow direction when totalling the consumed quantity
+Q: volumetric flow quantity in positive direction
-Q: volumetric flow quantity in negative direction
V: volumetric flow quantity absolute (= sum of negative and positive volumetric flow)
1: volumetric flow changes to negative direction
2: volumetric flow changes to positive direction
When the volumetric flow direction is changed a minimum volumetric flow quantity is taken into
account. See Switching signal for flow direction.

10.4.15 Reset the device
The device can be reset in two ways.
With both reset applications, the operating hours since the first set-up are not reset.
[APPL] = application reset
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
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.
Minimum and maximum memory value
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.
10.4.15.1 Resetting the device using device keys
uGo to menu [Settings] > [CFG] > [rES].
uSelect [APPL] or [BtB] and set [Yes].
