System Controls - Briggs & Stratton 040298 Service & Troubleshooting Manual

System Controls

—
A - Set Exercise Used to set the exercise cycle start time
and day-of-the-week. Exercise cycle only occurs in AUTO
mode.
—
B - Circuit Breaker Protects the generator from shorts
and other over-current conditions. Must be ON to supply
power to the automatic transfer switch.
—
C- 15 Amp Fuse Protects the 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.
—
D - 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.
—
E - Manual Over-RIde This function allows the
technician to manually start and stop the generator.
With system switch in the AUTO position, push and hold the
MANUAL OVER-RIDE for six seconds to start the generator.
To turn off the generator, push and hold MANUAL OVER-
RIDE until engine stops.
—
F- Digital Display Displays the total number of hours the
generator has been running and fault codes. It is used to
schedule maintenance tasks and for troubleshooting
operational problems with the residential generator. A
constant number displayed indicates the total hours of
operation. Fault conditions will flash "FC" followed by a fault
code number.
