The manual provides a detailed introduction to the functions of the EG3002 electronic engine governor controller, including the engine start smoke limiting function, IDLE speed setting, PT-Pump type actuators, and usage instructions.
The EG3002 is an electronic engine governor controller designed to maintain constant engine speed by comparing a magnetic pickup signal with a preset speed. It supports external, built-in, and PT-pump actuators, with settings for Cummins PT-Pump and 'extreme slow response' engines. The unit operates on 10–32 Vdc and features adjustable speed droop, ramp time, and idle speed. It includes DIP switches for frequency range selection and potentiometers for fine-tuning parameters like gain, integral, and derivative settings. Installation requires shielded cables and proper grounding to avoid noise interference. Safety warnings advise against over-speed operation and recommend external over-speed protection.
Wiring and adjustment procedures are detailed, including terminal connections for battery, actuator, MPU, and remote speed control. Initial setup involves selecting the correct frequency range based on engine RPM and flywheel teeth, adjusting idle and run speed, and calibrating gain, integral, and derivative settings for stable operation. Parallel generator operation is supported with adjustable speed droop for load sharing. The manual includes troubleshooting tips for engine start issues and speed instability.

Short terminals 2 & 3 and use the IDLE SPEED potentiometer to adjust the idle speed.
The EG3002 takes a signal from a magnetic pickup and compares it with a preset engine speed to control drive voltage to the actuator to maintain constant engine speed.
The controller provides a continuous current output of 7A minimum.
A speed droop of 2% at maximum load is recommended when a generator is used in parallel operation.
