Product Application
Protection level
These parameters define how the soft starter responds to different protection events. The soft starter can trip, issue a warning or ignore different Protection event. Write all protection events into the fault record.
Notice:
I = I Cancelling the protection mechanism may endanger the safety of the starter and motor, and should only be I I used in an emergency.
Options: 0: Trip and stop 1: Alarm and no shutdown 2: Ignore
Description: Select the response of the soft starter to each protection.
