8.11 Parameterising the M12 module
Installing an M12 module
(ðSection7.4.3.5,Page49)
If a function is parameterised at an M12 module socket contact (A or B) without such
a signal present at the device, the frequency inverter reports one of the following
messages:
▪ Failure of Actual Value warning
▪ No Master Control alert
▪ Broken Wire warning
This depends on whether the signal is to be used as an actual value source.
(ðSection8.8.2.6,Page91) It is not possible for the same M12 module socket
contact to be parameterised differently for the individual frequency inverters used in
multiple pump configurations.
Parameterising the M12 module for PumpMeter as an actual value source (via
Modbus)
If PumpMeter is connected to inputA of the M12 module via Modbus and used as
actual value source for control, the Function M12 Module Input A parameter must be
set to PMtr Suction / Discharge Pressure (3-8-4-1).
NOTE
When changing parameter 3-8-4-1 to the above-mentioned value (in particular in
retrofit applications) a 24 V voltage reset is triggered, which is required for
initialisation of the bus connection to PumpMeter.
