OVERSPEED SHUTDOWN
The Pre-pack circuit board on liquid cooled units
receives AC frequency (rpm) signals directly from the
stator AC power windings, via sensing leads S15 and
S16. Should AC frequency exceed about 72 Hz, cir-
cuit board action will automatically shutdown the
engine (Figure 1.7).

2002 GENERAC POWER SYSTEMS, ASSY #076009A
*Rated power of generator is subject to and limit-
ed by such factors as ambient temperature, alti-
tude, engine condition, and other factors. Engine
power will decrease about 3% for each 1000 feet
above 3000 feet and will decrease an additional
1.5% for each 10°F above 77°F . Maximum output
power of the generator is limited by maximum
engine power.

PCB OPERATION LED'S
• LED 1 is RED. The LED is ON when utility sensing
is NOT available to the circuit board. This LED will
function only when the AUTO/OFF/MANUAL switch
is set in the AUTO position.
• LED 2 is YELLOW. This LED is ON when the cir-
cuit board battery charger is on. This LED will
cycle ON and OFF with the battery charger, 4.85
hours on the 4.85 hours OFF.

• LED 3 is GREEN. This LED will flash when the cir-
cuit board has load voltage available to it. This
LED will function when voltage is available across
T1 and T2.

After 90 seconds of crank-rest cycles, this function
ends cranking if the engine fails to start in that
90-second span.

This clearly labeled fuse is located on the front panel
of the control system. It protects the panel wiring and
components from damaging overload. Always
remove this fuse before commencing work on the
generator. The unit will not start or crank if the fuse
is blown. Replace the fuse with one of the same size,
type, and rating. Carrier normally uses an AGC fuse
rated at 15 amps (part number 022676).

Handle shipping cartons and crates with care. Use
care to avoid damage from dropping, bumping, colli-
sion, etc. Store and unpack cartons with the proper
side up, as noted on the shipping carton.
