OVERSPEED SHUTDOWN

The CMA 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, circuit board action will automatically shutdown the engine (Figure 1.7).

*Rated power of generator is subject to and limited by such factors as ambient temperature, altitude, engine condition, and other factors. Engine power will decrease about 3.5% for each 1000 feet above sea level and will decrease an additional 1% for each 10°F above 60°F. Maximum output power of the gen- erator is limited by maximum engine power.

This clearly labeled fuse is located on the front panel of the control system. It protects the panel wiring and com- ponents 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. Generac normally uses an AGC fuse rated at 30 amps.

UNPACKING

UNPACKING PRECAUTIONS

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

INSPECTION

After unpacking, carefully inspect the generator for any damage that may have occurred during shipment. If loss or damage is noted at the time of delivery, have the person(s) making delivery note all damage on the freight bill or affix his signature under the consignor’s memo of loss or damage.

OVERCRANK SHUTDOWN

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

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.
