10.2.2.12
Description of parameters 41 and 42
41.A1 - response threshold of alarm 1
The factory setting is "10.0".
and
42.A2 - response threshold of alarm 2
Use these parameters to set the alarm thresholds that are used to trigger an alarm. The
response thresholds of the "41.A1" and "42.A2" alarms refer to the MPOS scale that
corresponds to the mechanical path.
The factory setting is "90.0".

10.2.2.13
Description of parameter 43
43. FCT - function of the fault message output
The fault message in the form of monitoring of control deviation over time can also be
triggered due to the following events:
●
Power failure
●
Processor fault
●
Actuator fault
●
Valve fault
●
Pressure failure
●
Response of limits
Note that the fault message cannot be switched off. It can however be suppressed (factory
setting) when you switch over to "No automatic mode". If you wish to generate a fault
message here, set the "43.FCT" parameter to "nA".
You also have an option to connect the fault message with the status of binary inputs using a
logical OR combination. For this purpose, set the "32.FCT" parameter to "nAb".
Select the "-" setting if you wish to forward the fault message to the alarm or SIA unit in an
inverted format.
The factory setting is " ".
