The 512/524 and 1712/1724 EPGs are three-component governing systems for 12 or 24 Vdc operation

All EPG systems include an actuator, an electronic speed control, and magnetic pickup

Isochronous electronic controls are available with either start-fuel limit or with switchselected dual dynamics

Droop controls are available for certain types of parallel generator application

Load sharing devices are available for use with the isochronous models used in paralleled applications

The selected EPG actuator is mounted on the prime mover and mechanically linked to the fuel control

The rotary design and output shaft on both ends gives 30° (512/524) or 35° (1712/1724) clockwise or counterclockwise travel to low-mass, lowfriction fuel linkages

Preloaded internal return springs supply the shaft torque in the decrease-fuel direction and for shutdown should the electronic control signal be lost

A rugged cast aluminum housing permits installation of the speed control on the engine skid

In operation, the control compares the speed of the engine with the desired speed or desired load and sets the actuator position to correct discrepancies

Gain and stability adjustments tailor the governor’s response to the specific engine

EPG controllers with switch-selected dynamics allow stable operation at no load and brisk response when the unit is heavily loaded
