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 time
of
the
actuator to the generator/engine load changes.
NOTE:
A high gain adjustment can induce an oscillating
of
the actuator producing a hunting mode. In such cases, lessen
the gain adjustment.
Calibration
1. With no power to the governor (engine not running)
adjust the GAIN potentiometer to
9:00 o'clock.
2.
Start the engine and adjust the speed by turning the
SPEED potentiometer clockwise to desired speed.
NOTE:
Controllers are factory adjusted to minimum rpm.
However, for safety, one should be capable
of
disabling the
engine
if
an overspeed should exist.
3. At
no
load, turn the GAIN potentiometer clockwise until
the engine begins to hunt.
If
the engine does not hunt,
physically upset the governor linkage.
4. Turn the gain potentiometer counterclockwise until the
engine runs stable.
