ELECTRONIC GOVERNOR
ELECTRONIC GOVERNING SYSTEM
The system is composed of three basic components:
1. Controller - Mounted inside the instrument panel box.
2. Sensor ~ Installed on the generator stator housing over the
flywheel ring gear.
3. Actuator - Mounted at the front of the engine and
attached with linkage to the throttle arm of the injection
pump.
Controller Adjustments
1. Speed. - This adjustment is used to raise or lower engine
speed
to the desired hertz.
2. Gain - This adjustment affects the reaction lime of the
actuator to the generator/engine load changes.
NOTE: A high Rajn adjustment can induce an oscillating of
the actuator producing a hunting mode. In such cases, lessen
the gait! adjustment.
Calibration
1. With no power to the governor (engine not running)
adjust the GAIN potentiometer to 9:00 o'clock.
