3.8 Troubleshooting Faults
When the Alarm LED is on, the unit has a fault, a condition where backup power is unavailable.
When the unit has a fault, and line power is qualified and present at the unit's input, the loads are
directly connected to the line with no line conditioning or backup power provided.
The fault submenu displays the unit's malfunction and is used for troubleshooting.
