Section 6 Troubleshooting
Flexstar Frequency:
Current frequency of HDx-FM exciter. This is information
obtained via the CAN bus from the HDx-FM exciter.
Check Exciter
Flexstar Sum Fault:
(OK/FAULT) FAULT if there is a fault condition in the exciter.
This information is obtained via the CAN bus from the Flexstar exciter.
Check Excitery
Exciter Ready:
(YES/NO) Status of operational state of exciter. This information is
obtained via the CAN bus from the Flexstar exciter.
Check Exciter
AFC Intlk Status:
(OK/FAULT) FAULT if the PLL cannot lock in the exciter. This
information is obtained via the CAN bus from the Flexstar exciter.
Check Exciter
CAN Bus Connection:
(OK/LOSS) If there is no CAN communication a LOSS will be
indicated. This information is obtained via the CAN bus from the Flexstar exciter.
