Acknowledging faults

Switching back on after device-internal tripping
If the motor starter trips the switching elements automatically, it will not switch back on until:
● The fault has been rectified
● The fault has been acknowledged
● The "Emergency start" device function has been activated; that is, the motor can be
switched on and off using the control commands in spite of a pending group fault (not in
the case of a device error!)
Acknowledging
You can acknowledge faults as follows:
● With "trip reset"
– DO0 and DO1 simultaneously (motor CW and motor CCW)
– "Trip reset" command
– "Trip reset" input action
– Key-operated switch (order variant) in position O
– Circuit breaker 0 → 1
– Device interface (hand-held device, Motor Starter ES)
● "Tripping with restart" (auto reset) parameterized
● With the opposite command, e.g. "motor OFF" (process image errors only)
Note
Trip reset is edge-triggered!
If trip reset is present permanently, acknowledgement is only triggered once.
