PRODUCT DESCRIPTION

Do NOT use the minimum-fuel contact as a part of any emergency stop sequence. The emergency may be caused by a governor malfunction which would also cause a malfunction of the minimumfuel feature. Use of the minimum-fuel contact for an emergency stop sequence could cause overspeed of the prime mover and mechanical 

damage and personal injury, including death.

Benefits:

Speed Control 

The speed control box should be mounted on the control panel, often on the 

same skid as the engine. It is not designed for installation on the engine. Provide 

space for adjustment, wiring access, and ventilation. Choose a location that 

protects the control from being bumped and that the wiring harness will reach. 

The installation should allow for adequate air circulation to the control box and 

have an ambient temperature of –40 to +75 °C (–40 to +167 °F). 

Actuator 

Install the actuator solidly, and install a linkage with the correct configuration to 

provide an almost linear relationship between change of actuator position and 

change in engine power output. In most cases use about 2/3 of the actuator 

rotation between minimum and maximum fuel. The engine fuel control usually 

provides the minimum and maximum stops. The minimum and maximum stops 

on the actuator may be used, if necessary (see Figure 2-1). If the actuator is 

controlling the speed-setting shaft of a mechanical governor, use the actuator 

stops to limit the travel of the linkage. Set the minimum stop for 5% below rated 

speed at no load, and set the maximum stop for rated speed plus 3% more than 

the droop of the governor. The actuator is designed to operated in ambient 

temperatures of –40 to +82 °C (–40 to +180 °F). Installation should avoid sources 

of excessive heat. 

Do not pressure wash sealed bearings—you may force dirt inside 

them, shortening their life. If the actuator is exposed to weather, 

mount it with the clockwise end higher, if possible. 

Magnetic Pickup (MPU) 

Install the magnetic pickup on a rigid bracket or housing so its tip is near an 

engine-driven gear. This gear must be made of a ferrous material that reacts to a 

magnetic field. Adjust the MPU for 0.25 to 1.0 mm (0.010 to 0.040 inch) between 

the gear and the MPU at the closest point. 

Electrical Connections 

Connect the system as shown in the appropriate wiring diagram (Figures 1-2, 

1-3, 1-4). See the appropriate manual for wiring of accessories. Connect the 

speed control to system ground.
