Controller Module Front Panel Alarm Checks
There two ways to check for alarms on the front panel:
 Alarm/Status LEDs
 View Alarms Screen - see page 4.1.8
Alarm/Status LEDs
There are four LEDs on the left-hand side of the LCD display that provide information about the
operational status of various sections of the transmitter -
Exciter
,
Power Amplifier
,
Output Network
and
Power Supply
(see Figure 4.1.2 ). The LEDs can glow green, amber or red. Typically, green indicates
normal operation, amber indicates a warning, and red indicates a fault or error.
Figure 4.1.2: Controller Module Alarm/Status LEDs
When an LED is:
 Green - transmitter is on, with no known faults.
 Amber - a fault is present that may cause a reduction in RF power, but the transmitter is still
producing RF power.
 Red - a fault is present and the transmitter is not producing RF power.
When a fault is present, the transmitter may still produce an RF output. In this case, or if the transmitter
has shut down, you should schedule and commence more in-depth fault diagnosis. See
“View Alarms
Screen” on page 4.1.8 .
