15 kW Generator
With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer switch. The following should occur:
•After about six seconds, the switch should transfer loads back to the utility power source.
•About one minute after retransfer, the engine should shut down.
2.6ADJUSTING THE REGULATOR
(NATURAL GAS ONLY)
Although the generator has been factory set to pro- vide maximum power, it may be necessary in some areas to adjust this setting. Because natural gas has different BTU or power content across the country the engine may not perform as designed.
If experiencing engine problems at high or full load conditions follow these steps. It will require a fre- quency meter to perform this procedure.
1.Turn off utility power to the main distribution panel in the house. This can be done by switching the service main breaker to the off or open posi- tion.
2.Allow the generator to start before loading the generator. Confirm the
3.Turn on appliances, lights, pumps, etc., that are on the emergency circuits in an attempt to fully load the generator. Be cautious not to overload the generator. Use the following chart as a guide:
| Unit | 120 Volts | 240 Volts |
|
| 15 kW | 108.3 amps | 54.2 amps |

4.When full load has been achieved. Connect a fre- quency meter to the output lugs of the generator’s main line circuit breaker.
5.The fuel regulator is fitted with two adjustment screws. While watching the frequency meter, slowly turn the adjustment screw clockwise or counterclockwise one at a time until highest fre- quency is read on the meter. Only limited adjust- ment is available between the set pins. Under no circumstances should any of the pins be removed (Figures 2.1 and 2.2).
7.Turn utility power to the main distribution panel back on. This can be done by switching the ser- vice main breaker to the on or closed position. Allow the generator to shut down.
Do not make any unnecessary adjustments. Factory settings are correct for most applica- tions. However, when making adjustments, be careful to avoid overspeeding the engine.
If this procedure or equipment are not available, locate the nearest Dealer and they can perform the adjustments.
NOTE:
A service fee may be charged for this adjustment.
