DC OK
DC OK will be put on with green light if the DC output is OK.
DC OK will be put out if the output voltage is below 50% of
nominal voltage. This means that it is also put out in normal standby state.

ALARM
The ALARM-led is put out in normal operation.
Red light indicates a fault condition. Also
standby state will give red light, because by the
systems point of view it is considered as a fault
condition.
The cause of the alarm can be studied in detail using the monitoring unit menu system, see
Manual for monitoring unit PCM2
