Action in permanent fault
state
If relay SW has just been
updated, redo it. If not re-
covered, contact your near-
est ABB representative to
check the next possible
corrective action.
Restart the relay. If recov-
ered by restarting, contin-
ue relay normal operation.
If not recover by restart-
ing, replace the relay, most
probably hardware failure
in CPU module.
Do factory restore or re-
write configuration using
PCM600.
Do factory restore. If not
recovered, contact your
nearest ABB representative
to check the next possible
corrective action.
Restart the relay. If recov-
ered by restarting, contin-
ue relay normal operation.
If not recover by restart-
ing, replace the relay, most
probably hardware failure
in CPU module.
Restart the relay or if relay
SW has just been updated,
redo it. If recovered by re-
starting, continue relay nor-
mal operation. If not recov-
ered by restarting or redo-
ing SW update, replace the
relay, most probably hard-
ware failure in CPU module.
Restart the relay. If recov-
ered by restarting, contin-
ue relay normal operation.
