GENERATOR OPERATION

A standby generator is an engine driven air cooled system to convert the energy contained in either liquid propane vapor or natural gas to electrical power. When coupled with an automatic transfer switch to monitor for failure of utility power, the unattended system can start, stop and transfer between sources to insure a nearly seamless supply of power. The generator is housed in a weather resistant, sound attenuated enclosure for outdoor installation only.

Before installing and starting the generator, become familiar with the controls and operational features of the generator. Know how the control panel operates, what to expect when activating control panel switches and how to shut the generator off in the event of an emergency.

the AUTO position sets the generator for unattended operation under the control of properly matched automatic transfer switch.

B. Main Line Circuit Breaker

A Main Line Circuit Breaker is provided to protect the generator from damage caused by electrical faults within the attached electrical distribution system. It is also used to isolate the output of the generator from the connected electrical distribution system by moving the breaker handle to the OFF position. Placing the breaker in this position does not prevent startup of the generator.

C. Status Indicator Lights

Status indicator lights are provided to communicate the status of the generator to the user. Under normal running conditions, only the green Generator On light is lit. Function of all other lights are described on page 24.

D. Generator Hour Meter

The Generator Hour Meter is provided to track the total numbers of hours of operation. The hour meter runs whenever the engine is running and the alternator is producing electricity. Placing the main line circuit breaker in the OFF position while the engine is running does not stop the meter from counting hours.

E. Lamp Test Switch

A lamp test switch is provided to check for function of all indicator lights. Press the lamp test switch while the engine is at rest, with the control panel mode switch in the OFF position to illuminate all status lights.

F. Engine Charging Circuit Fuse

The Engine Charging Circuit Fuse provides protection to the engine mounted alternator in the event of electrical faults in the positive (+) battery circuit. Failure of this fuse prevents charge from reaching the battery when the generator is running, leading to early battery failure. Replace the fuse only with an equivalent size and style of fuse to prevent damage to the generator electrical control system.

A. Mode Switch

The Mode switch is used to set the operating state of the generator. Placing the switch in the OFF position prevents engine operation or stops the engine if it is already running. Moving the switch to the RUN position immediately starts the generator. Putting the switch in
