CONTROLS
HOUR METER:
These generators are equipped with an hour meter that records run time
for the unit. This is very useful in scheduling maintenance. See periodic
maintenance chart for suggested maintenance schedule.
VOLT METER:
These generators are equipped with a volt meter. The volt meter is used
to monitor the unit for proper voltage.
IDLE CONTROL OPERATION:
The idle control is factory installed. This electrical device is designed to
let the engine run at fuel saving low idle speed when the generator is not
loaded, and at full normal governed speed when a load is applied. The
idle system overrides the engine governor to provide idle speed. When
a load is applied, the electronic circuit reacts to de-energize the idle
system so that the engine can resume full governed operating speed.
The idle control system controls the engine speed in the following
manner:
1. With the idle control switch in the “OFF” position, start the engine.
2. After one or two minute warm up period, apply load and move the
switch to the “ON” position. The engine will throttle back to idle speed
following a 5-8 second delay.
3. When a load is applied to the generator, the idle control system
becomes de-energized. The engine then accelerates to normal
operating speed, controlled by the governor.
4. When the load is removed, the idle system becomes re-energized and
throttles the engine back to idle speed after a 5-8 second delay.
NOTE: While the engine is idling, the generator voltage is automatically
reduced to reduce generator temperatures. The voltage will return
to normal levels immediately upon the application of load.
MAIN BREAKER (AC-G6010 units only):
These generators are equipped with a main circuit breaker which
protects the unit in an overload condition. This main breaker must be
“ON” for any power to be drawn from the unit.
