Trip level (CiR), warning level (CiR)
You can parameterize two different response levels (trip level, warning level) for earth-fault
current monitoring.
If the earth-fault current exceeds the set response level, the earth-fault monitoring function
responds.
Trip level:
Warning level:
Note
(CiR): Change in Running
The parameters followed by (CiR) can be changed when the motor is in operation.
Active status trip level, warning level
Unless deactivated, this function is always active, independent of whether the motor is
running or not (operating state "ON").
Here you can specify in which motor operating states the trip level/warning level is to be
active.

Response at trip level
Here you can set how SIMOCODE pro should respond if the trip level is undershot.
