SECTION 1 : SUMMARY
The EG300
0
electronic controller takes a signal from a magnetic pickup (MPU) and compares it with a preset engine
speed to control drive voltage to the actuator to maintain constant engine speed. The EG3002 has engine start
smoke suppression, IDLE Speed control, Ramp Time setting, applicable for MPU frequency range of 600 to 9500 Hz.
The unit has settings for use with Cummins high-gain (PT PUMP) engines and “extreme slow response” engines.
