(Firs and second points are same to idle speed.) This will set the run speed potentiometer to its mid position. This will set the idle speed potentiometer to its mid position. Turn the screw counterclockwise 20 turns.ģ. If two terminals on the control terminal strip are shorted, it can damage the control unit.ġ. The panel mounted governor control wiring.Ĭaution: Measure the voltage on the engine control circuit board terminal strip and not on the control terminal strip. A clockwise rotation will increase the run speed.Īn idle-run switch, located on the engine instrument panel, allows the selection of the idle or run mode.Īlso located on the engine instrument panel is the Speed Adjust potentiometer which is used for fine speed ajustment after Run Speed, Droop, and Gain have been set. The run speed control is a 20 turn potentiometer for setting the desired no-load governed speed. A clockwise rotation will increase the idle speed. The idle speed controi is a 20-turn potentiometer for adjusting the idle speed. Counterclockwise rotation will decrease the speed droop. It is adjustable for zero % (isochronous) to five % speed droop. The droop control is a one-turn potentiometer. Refer to the glossary for the gain drescription. A clockwise rotation of the potentiometer dial will shorten the response time of the governor to load changes. It is used to adjust the sensitivity of the governor. The gain control is a one-turn potentiometer.
