Table 2-4. Harmonic Frequency Range
A carrier signal of carrier-rated power and a system applicable modulation
Power interruption exceeds the transparency time
Upon power-up and until the first ARINC-429 Label 143 HPA Command Word
received with the state of indication of "PA Control" identified as "Carrier ON"
Over-temperature exceeding critical level
Fault conditions of the HPA preclude operation
The HPA is executing a Self Test
The detection of a single event upset that requires reset remedial action
Input Attenuator level has not been defined by ARINC 429 label 143 HPA
Command word "PA Backoff"
Control Bus Input is compromised.
Receipt of ARINC-429 Label 143 HPA Command Word "PA control" set to
"Carrier On"
No inhibitions are present holding the PA function as disabled.
Receipt of ARINC-429 Label 143 HPA Command Word "PA control" set to
"Carrier Off"
Presence of any inhibitions complying the PA function to be disabled.
