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:
30 mA ... 40 A in 10 mA increments (default setting: 1000 mA)
Warning level:
20 mA ... 40 A in 10 mA increments (default setting: 500 mA)
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.
always (on)
trip level/warning level always active, regardless of
whether the motor is running or at a standstill
if motor is running, except TPF (run)
trip level/warning level only active if motor running.
if motor is running, except TPF, with
startup override (run+)
trip level/warning level only active if motor running
and start procedure completed.
Response at trip level
Here you can set how SIMOCODE pro should respond if the trip level is undershot.
