5.3 Adjustments before starting the engine
Check to insure the GAIN and STABILITY adjustments, normally this value is set mid position by factory.
Leave factory conditions of Red State Switch is , namely RSW-1, RSW-3 = OFF, RSW-2 = ON.
Rated and idle speed of the speed Governor had been set by factory. Normally, this value is near from the
user’s engine working rotate speed value. In practice, after some adjustments, governor can achieve rated
and idle speed, and the stability would be very well.
5.4 Adjustment of the governor after starting
5.4.1 Crank the engine with D.C. power applied to the governor system. Start fuel quantity varies with
environmental temperature of engine start. Though adjusting start fuel quantity potentiometer;
exhaust smoke from the engine can be adjusted to the best state.
5.4.2 The governor system should control the engine at low idle speed. If the engine is unstable after
starting, turn the GAIN and STABILITY adjustments counterclockwise until the engine is stable.
5.4.3 The governed speed set point is increased by clockwise rotation of the SPEED adjustment control.
Remote speed adjustment can be obtained with an optional Speed Trim Control.
5.4.4 Once the engine is at the operating speed and at no load, the following governor performance
adjustments can be made.
5.4.4.1 Rotate the GAIN adjustment clockwise until instability develops. Gradually move the
adjustment counterclockwise until stability returns. Move the adjustment one division
further counterclockwise to insure stable performance.
5.4.4.2 Rotate the STABILITY adjustment clockwise until instability develops. Gradually move the
adjustment counterclockwise until stability returns. Move the adjustment one division
further counterclockwise to insure stable performance.
5.4.4.3 Gain and stability adjustments may require minor changes after engine load is applied.
Normally, adjustments made at no load achieve satisfactory performance. A strip chart
recorder can be used to further optimize the adjustments.
5.4.5 After the governor speed setting has been adjusted, place the optional external selector switch in
the IDLE position. The idle speed set point is increased by clockwise rotation of the IDLE
adjustment control. When the engine is at idle speed, the speed Governor applies droop to the
governor system to insure stable operation.
5.4.6 Through the above adjustments engine still unable to stability, it needs to be adjusted Red State
Switch now, the following figure shows four cases
a : RSW-1 RSW-3 = ON RSW-2 = OFF
b : RSW-1 RSW-2 = OFF RSW-3 = ON
c : RSW-1 RSW-2 = ON RSW-3 = OFF
d : RSW-1 RSW-3 = OFF RSW-2 = ON
After every adjusting Red State Switch go on the 5.4.4.1 and 5.4.4.2 adjusting procedure again. If
it is still unable to stability, should inspect engine and fuel pump for service condition. And then,
contact with manufacturer.
