8.10. Alarm and fault handling
Two protection levels are used in the PCS6000:
– Alarm: does not shut down the PCS6000. A start is possible.
– Fault: always shuts down the PCS6000 by means of a trip. The start is prevented.
8.10.1. Alarm and trip reset
Press the ACKNOWLEDGE ALARM or ACKNOWLEDGE TRIP function key or select the
appropriate command from remote control to reset all pending alarms and trips.
If an alarm or fault cannot be reset, the original alarm or fault cause might still be present.
Ensure that the cause is removed and press the ACKNOWLEDGE ALARM or ACKNOWLEDGE
TRIP function key again.
Faults caused by defects cannot be reset with the ACKNOWLEDGE TRIP function key.
Elimination of these faults requires troubleshooting by authorized service personnel.
The PCS6000 can only be started if all faults are eliminated.
