ALARMS

The following table lists all the alarms for the DCU4000. If the alarm is latched, the alarm is
cleared by using the clear alarm command. These are coded into the remote command set
as described in section 4.36.

F1: DCU POWER SUPPLY VOLTAGE LOW

The antenna DCU has measured a voltage below 9.5V at the antenna electronics. The
voltage supplied from the 12V nominal supply is approaching the minimum required to drive
the antenna. Action should be taken to boost the 12V supply to the DCU.
