Section III. GOVERNOR CONTROLLER
4-11. GENERAL. The governor controller A106 (56,
figure 4-1) is the electronic portion of the load sharing
and speed control unit which is part of the electric
hydraulic governing system. The governor controller has
two major functions, speed control and load sharing. It
measures engine speed via a magnetic pickup and
compares it to a speed reference. It then feeds
corrections to the hydraulic actuator governor on the
engine. It also has a speed sensing fail safe circuit, and
a time ramp circuit (deceleration to idle speed -
acceleration to rated speed).
4-12. INSPECTION. Inspect the governor controller
front panel by removing the access cover (7, figure 4-1),
paragraph 4-2. Inspect the connections on terminal
boards for loose wires, inspect the potentiometers for
signs of damage, and the control panel for scratches,
dents or other damage.
4-13. ADJUSTMENTS. The controller has eight
adjustment controls located on the front cover. Perform
the following adjustments whenever the unit is replaced.
NOTE
Do not adjust the DE-DROOP, RAMP
TIME,
and
LOW

SPEED
adjustments on the unit. These pots
are factory set on each controller.
a.
Disconnect F- and F+ leads on voltage
regulator.
b.
Set RATED SPEED (10T) potentiometer
fully counterclockwise, then rotate 4 turns
clockwise.
c.
Set the STABILITY, GAIN, LOAD GAIN,
and DROOP potentiometer to mid-range
positions.
d.
Toggle
the
FREQUENCY
SELECTOR
switch on the AC-DC Control Panel to the
50 Hz position.
e.
Start the generator set.
f.
Adjust
the
RATED
SPEED
(10T)
potentiometer to obtain 50 Hz. Monitor the
FREQUENCY meter on the Control Cubicle.
g.
Toggle the FREQUENCY SELECTOR
