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 PAST ALARM). 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.
