System Control Panel
Compare this Control Panel illustration with your generator to familiarize yourself with the location of these important controls:
A - Circuit Breaker — Protects the system from shorts and
other over-current conditions. Must be ON to supply
power to the Automatic Transfer Switch.
B - Set Exercise Button — Used to set the exercise cycle
start time and day-of-the-week. Exercise cycle only
occurs in AUTO mode.
C - Manual Over-Ride Button — With system switch in
AUTO position, push the manual over-ride switch to
start the generator. To turn off the generator, push and
hold the manual over-ride switch again until engine
stops.
D - 15 Amp Fuse — Protects the home generator 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 ATO 15A fuse.
E - System Switch — This two-position switch 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. When utility power is restored, AUTO lets
the engine stabilize internal temperatures, shuts off the
generator, and waits for the next utility power outage.
• “OFF” position turns off running generator, prevents
unit from starting and resets any detected faults.
F - Digital Display — Displays the total number of hours
the generator has been running and fault codes. Used
to schedule maintenance tasks and for troubleshooting
operational problems with the home generator. All fault
conditions are described in Fault Detection System.
