Rack #: Residual PA
Volts (Residual PA V)
Exciter (red)
This alarm indicates that after the transmitter has turned off its RF output, it
is unable to discharge the PA volts to a level that is below 10 V. This
condition will not allow the transmitter to turn on its RF output; however
the condition will be cleared once the PA volts reaches a level that is below
10 V. If the condition cannot be cleared automatically, the transmitter will
still be allowed to turn on. This condition will typically occur with a failed
PA or power supply module. Check for associated alarms and follow the
associated troubleshooting procedure.
Rack #: +15V Fail
Power Supply (red)
This alarm occurs if the +15 V supply on the module control/interface PWB
(A3) is outside its acceptable voltage range (b13.5 and +16.5 V).
Rack #: +3.3V Fail

Rack #: +5V Fail
