– OU: The output switches ON for pressure measurement and OFF for flow measurement and
temperature measurement.
•
Analogue signal:
– On: The analogue signal goes to 21.5 mA.
– OFF: The analogue signal goes to 3.5 mA.
– OU: The analogue signal goes to 21.5 mA for pressure measurement. The analogue signal
goes to 3.5 mA for flow measurement and temperature measurement.
The parameter FOUx is not available if [ou] = Imp (consumed quantity monitoring) is selected.
The pulses are provided independent of the fault.
