EPG Electrically Powered Governor SystemsThe 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 switch-selected 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.
