Guardian Liquid-cooled 15 kW, 20 kW and 25 kW Generators

• LED 2 is YELLOW. This LED is on when the circuit

 

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.

‹ 1.7.6 OVERCRANK SHUTDOWN

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

‹1.7.4 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).

*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 3.5% 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 generator is limited by maximum engine power.

‹1.7.6 DC FUSE

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. Generac normally uses an AGC fuse rated at 15 amps (part number 022676).

1.8UNPACKING

‹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.

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