Alarm Description
1 Power PSU Critical PSU1 in the cabinet does not work properly. A sum signal from
the PSU1 indicates that at least one voltage output has dropped.
If no mains breakdown relay is used, then the alarm will also be
sent at mains breakdown.
Ceasing PSU1 in the cabinet works properly again. Ceasing is sent if the
PSU1 works at start-up, and there is a corresponding critical
PSU1 alarm logged in the Events log. The WRH will restart when
the power is back and this alarm will be sent.
