Enhanced Electronic Governor
1
INTRODUCTION
GAC’s EEG7500 enhanced electronic governor is designed to regulate engine speed
on diesel and gaseous fueled engines. When paired with a GAC actuator the EEG is
a suitable upgrade for any mechanical governor system that needs flexibility, preci -
sion, or accurate control of governed speed. The EEG7500 is designed for industrial
engine applications from generator sets, mechanical drives, pumps, and compressors
to off-road mobile equipment. Configuring is easy with GAC’s free GAConfig Tool
software. The EEG7500 supports:
Š
Flexible actuator compatibility including bidirectional actuators with or without
actuator position feedback signal, bi-directional torque motors, and Bosch-style
throttle bodies.
Š
Fully configurable digital and analog inputs and outputs
Š
Inputs: 5 analog, 2 digital
Š
Outputs: 1 analog, 3 digital
Š
0 - 5 V DC, 4 - 20 mA, 0 - 10 V DC, or ±3 V DC input ranges
Š
Speed Sync using CAN bus
Š
Virtual Input/Output Routing
Š
Feedback Speed Control Mode
Š
Variable Speed Capability

Fuel Curve Shaping
EEG7500 supports three operating modes :
Š
Non-Feedback Speed Control (NFSC) provides standard PID governing function for use with proportional actuators. No position
feedback sensor is required. PID (Proportional, Integral, Derivative) governor functions are optimized for best response and control
of the requested engine revolutions per minute ( rpm).
Š
Feedback Speed Control (FSC ) combines NFSC and PM modes for use with proportional or bidirectional (torque motor) actuators. A
position feedback sensor is required. The Speed PID position request is the input to the Positioner loop, the Position PID optimizes
response and control of the requested actuator position.
Š
Positioner Control (PC) (uncommon) provides actuator positioning control and is used with proportional actuators or bidirectional
(torque motor) actuators with a feedback sensor (required).
