Fuse

 

15 Amp Fuse — Protects the Backup Power System DC control circuits. If the fuse has ‘blown’ (melted open) or was removed, the engine cannot crank or start. Replace the fuse using only an identical BUS AGC 15A fuse.

AUTO/OFF/MANUAL Switch — This three-position device is the most important control on the system and is used as follows:

•“AUTO” position is the normal operating position. If a utility power outage is sensed, the system will start the generator, let it reach stable operating speed, then connect generator power to the sub-panel.When utility power is restored, the system reconnects utility power to the sub-panel, lets the engine stabilize internal temperatures, shuts off the generator, and waits for the next utility power outage.While waiting, it maintains battery with trickle charge.

•“OFF” position turns off running generator, takes system out of Automatic mode and resets any detected faults.

•“MANUAL” position starts the engine but does not disconnect the sub-panel from utility power. It is used for maintenance or diagnostic functions.

Circuit Breaker — Protects the system from shorts and other over-current conditions. Must be ON to supply power to the Automatic Transfer Switch.

Diagnostic LED — Used for troubleshooting operational problems with the Backup Power System.All fault conditions are described in the section “Fault Detection System”.

Hour Meter — The hour meter records the total number of hours the generator has been running and is used to schedule maintenance tasks.

Set Exercise Switch — Used to set the exercise cycle start time and day-of-the-week. Exercise cycle only occurs in AUTO mode.
