RECOMMENDATIONS
1.
Shielded cable should be used for all external connections to the ESD
control.
2.
One end of each shield, including the speed sensor shield, should be
grounded to a single point on the ESD case.

STARTING THE ENGINE
IMPORTANT
The speed control unit governed speed setting is factory set at approximately
engine idle speed. (1000 Hz., Speed sensor signal or 600 RPM)
Crank the engine with DC power applied to the governor system. The actuator
will energize to the maximum fuel position until the engine starts. The governor
system should control the engine at a low idle speed. If the engine is unstable
after starting, refer to Section 5 ADJUSTING FOR STABILITY.
ACTUATOR
The governed speed set point is increased by clockwise rotation of
NOTE
the SPEED adjustment control. Remote speed adjustment can be
obtained with an optional 5K Speed Trim Control.

ADJUSTING FOR STABILITY
Once the engine is running at operating speed and at no load, the following
governor performance adjustments can be made to increase engine stability.
1.
Rotate the GAIN adjustment clockwise until instability develops. Gradu-
ally move the adjustment counterclockwise until stability returns. Move
