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.
