1.7.4 OVERSPEED SHUTDOWN
Should AC frequency exceed about 72 Hz, circuit
board action will automatically shutdown the engine.
1.7.5 OVERCRANK SHUTDOWN
The engine control board uses a cyclic cranking
process when attempting to start the engine. The first
crank cycle is a 15-second crank followed by a seven-
second rest. This is followed by five more crank
cycles each with a seven second crank followed by a
seven-second rest.
If the engine fails to start after all six attempts, the start
attempt is stopped and the overcrank LED turns on.
1.7.6 LOW BATTERY
The engine control board continually monitors the
battery voltage and turns on the low battery LED if
the battery voltage falls below 12 VDC for one minute.
Low battery voltage is a non-latching alarm, which
will automatically clear if the battery voltage rises
above 12 VDC.
1.7.7 15A DC FUSE
This fuse is located inside the control panel. It pro-
tects the panel wiring and components from damag-
ing overload. The unit will not start or crank if the
fuse is blown. Replace the fuse with one of the same
size, type, and rating.
1.8 UNPACKING
1.8.1 UNPACKING PRECAUTIONS
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.
1.9 LIFTING THE GENERATOR
When lifting or hoisting equipment is used, be
careful not to touch overhead power lines. The
generators weight of more than 900 pounds
requires proper tools, equipment, and qualified
personnel to be used in all phases of handling
and unpacking.
