5.7 Alarm System
An alarm is indicated by one of the 3 red LEDs located on the front panel of the digital exciter.
The first LED alarm is for transport stream (TS) absence (SYNC. LOSS). The next LED alarm
is for a current malfunction present on the equipment, and requires investigation, (see CURRENT
ALARM). The third LED indicates a past alarm (see PASTALARM). This situation indicates that
an alarm is no longer present. On normal operation, just a green LED is ON, which confirms
that the AC input power is present. Once a CURRENT ALARM LED is ON, the origin of the alarm
should be investigated.
5.7.1 Current Alarms
If there is an alarm occurrence, this screen shows the current alarms.
Starting from the Main Menu screen:
