Fault

If a fault is pending , the associated error message on the information level can
be queried via the info button or the error history on OL 6800-6808. The display
describes the cause of the error.
Pending errors are assigned priorities. As of priority < 6 any configured alarm
output K10 (OL 5890) is enabled.

Line no. Operating line
6710 Reset alarm relay
No
Yes
When a fault is pending, an alarm can be triggered on relay ZX1. Relay ZX1 must
be configured accordingly.
This setting is used to reset the relay, but the alarm is maintained.
Line no. Operating line
6800...6808 Time stamp and error history 1 - 5
The basic unit stores the last 5 faults in non-volatile memory. Any additional entry
deletes the oldest in the memory. For each error entry, error code and time of
occurrence are saved.
Possible error messages are listed in Section "List of displays".
Line no. Operating line
6820 Reset history
No
Yes
The error history with the last 5 errors, the associated actual values and setpoints
and the relay output states will be deleted.
