Responding to Faults

Description
Responses to faults can be parameterized either as warnings or
trips. Example: "Response to asymmetry",
"Response to temperature sensor overload".
The following diagram illustrates how the motor starter responds (depen-
ding on how it has been parameterized):
Signaling bit: General warning set
LED indicator: DEVICE flashes yellow
Motor and brake: Not deactivated
Fig. 5-1: Responding to faults
Attention
In the event of a fault ("Process image error") or device fault ("Switching ele-
ment defective"), the response is always trip.
Responses to faults cannot be parameterized.
