The CDM-570L uses a system of Fault Prioritization. This system cuts down
significantly on unwanted and irrelevant fault reporting. In each category of fault,
only the highest priority fault is displayed. For example, if the demodulator is
unlocked, it is irrelevant if there are other receive 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
ODU Status 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
