System Fault Notications:
As a part of the built-in system monitoring, the BOSS controller will fault if certain errors occur.
When a fault occurs, the built-in sounder on the BOSS controller will sound and a fault code will
appear on the BOSS’s display. If there are multiple faults, display will scroll between them.
Explanation of System Faults:
