GAC’s Most Enhanced Electronic Controller
The EEG7500 is an Enhanced Electronic Digital Speed Controller that operates either bidirectional motors or proportional actuators with or without a position feedback signal. The EEG7500 provides extra performance and stability in speed governing, precise fuel limiting and flexible authority for torque curve shaping, making it the best choice for variable speed applications. It’s compatible with actuators other than proportional actuators (torque motor, Bosch throttle body, etc.) and has actuator position control without speed control (Lambda ratio control, EGR valve, etc.)
- 3 Operating Modes:
- Variable Speed with Position Feedback Governing for Variable Speed Applications Offers incredible transient performance even on fixed speed applications
- Fixed Speed Governing without Position Feedback
- Actuator or Motor Positioner with Position Feedback
- Compatible with Bidirectional Motors and Proportional Actuators.
- Built-in USB Port for Easy Configuration
- Flexible I/O:
- 4 Analog and 2 Discrete Inputs, 1 Analog and 3 Discrete Outputs
- Accepts 0-5V, 4-20mA, 0-10V or +/-3V Input Signals
- CAN SAE J1939 and RS232 Communications
GAC’s EEG7500 digital governor is designed to regulate engine speed on diesel and gaseous fueled engines. When paired with a GAC actuator, the EEG system is an upgrade for any mechanical governor system that needs flexibility, precision, or accurate control of governed speed. The EEG is designed for industrial engine applications from generator sets, mechanical drives, pumps, compressors, and off-road mobile equipment.
Programmed using GAC’s Config Tool Software, the EEG is set up with a user-friendly interface for application configuration as well as diagnostics and ease of troubleshooting. The GAConfig Tool is a free download from GAC’s Website.

Application of the Month:
Irrigation System Powered by a Cummins VT1710 – 28.0L, V12 Engine Equipped with:
- Two GAC – ATB652T2F14-24 Integrated Actuator Throttle Bodies (ATB’s) one on each bank.
- GAC’s DDM101 – Dual Driver Module that uses the two actuator position feedback signals and two exhaust temperature sensors to balance the fuel flow to each bank maintaining equal exhaust temperatures.
- GAC’s ESD5111 Speed Controller, this single governor controls the load response of both balanced actuators.
|GAC’s Dual Driver System is available for both gaseous fueled and diesel engines using a variety of Feedback Sensor Equipped Actuators.
HOW DO I ADJUST THE IDLE AND MAX SPEEDS ON MY ATB THROTTLE BODY ACTUATOR?
An adjustable Idle Stop screw (Min Throttle Adjustment) and Max Throttle Adjustment are provided to set a fixed opening if desired. The diagram below generally shows where the adjustments can be found on each ATB model.
NOTE: The Max Throttle Stop is preset to 65° rotation.
- You must completely remove the first sealing screw. This will give you access to the inner set screw.
- Using a 2.5mm Hex wrench, turning the wrench clockwise will increase the fixed throttle opening.
- Adjustment is complete once you have replaced the sealing screw. Apply Loctite 518 or equivalent. The sealing screw should be tightened to snug plus ¼ turn.
GAC will be closed Friday, July 3rd, 2020 for Independence Day and will reopen Monday, July 6th.
