2.1 FAILSAFE

The failsafe LED is coupled directly to the failsafe input on the back panel. Green indicates

the failsafe is connected for normal operation. If red the failsafe is not connected and RF

power will not turn on.

2.2 AUDIO

The audio LED indicates the status of the current primary audio source. If an audio peak

silence condition is detected, this LED turns red. The LED remains green until a failure is

detected. Check the exciter diagnostics for details on what alarms or faults may be active.

2.3 EXC DRV

The exciter drive LED indicates the status of any alarms or faults related to the exciter. Green

indicates that the exciter has settled into normal operating conditions. Orange indicates an

alarm condition. Red shows when the exciter has a fault condition. See Table 2 – Exciter

Diagnostics Details in section 7.5 for more information.

Note that there is overlap between internal exciter and internal PA status for drive detection.

An exciter drive alarm indication may originate from the PA. The exciter must also establish

frequency lock as it powers up. These are intended to indicate conditions that prevent full

operation whether the conditions are expected or not. Check the exciter and PA diagnostics

for details on what alarms or faults may be active.
