The CDM/R-570AL uses a system of Fault Prioritization. This system cuts down
significantly on unwanted and irrelevant fault reporting. Only the highest priority
fault is displayed in each category. For example, if the demodulator is unlocked, it is
irrelevant if there are other Rx faults present. If the demodulator then locks, but
there is a fault of a lower priority present, this will then be displayed. This also holds
true for the faults reported via the remote control.
SUMMARY OF PRIORITIZED ODU FAULTS
1) BUC PLL lock fault
2) BUC Current Out of Limits
3) BUC Voltage Out of Limits
4) LNB Current Out of Limits
5) LNB Voltage Out of Limits
6) BUC Temperature Alarm
7) BUC Software Checksum Error
