Parameterising the M12 module as an analog input
NOTE
The parameter values and value ranges/units entered are mutually dependent. This
is why the first step in parameterising the frequency inverter is always to specify the
applicable value range and units (refer to parameter 3-11). If the value range or
unit is subsequently changed, all dependent parameters must be checked for
correctness again.

Internal operating values cannot be used
as an actual value source.
▪ OFF
▪ Suction pressure

If the analog input of the M12 module is used as an actual value source for control,
the Function M12 Module Input A (3-8-4-1) or B (3-8-5-1) parameters must be set to
Suction Pressure or Discharge Pressure.
If the analog input of the M12 module is only used as an internal measured variable
and not for control, the Function M12 Module Input A (3-8-4-1) or B (3-8-5-1)
parameters must be set to Suction Pressure_Internal or Discharge Pressure_Internal.
NOTE
Only sensors with 4 - 20mA signals can be connected to the M12 module.
M12 module for PumpMeter as actual value source (via Modbus) in dual pump
configuration
PumpMeter devices to be used for Etaline Z pumps equipped with frequency
inverters are provided with a special firmware version at the factory to serve as
Modbus master. The two frequency inverters are set to Modbus slave. This is the only
