GAC’s EEG6500 digital governor is designed to regulate engine speed on diesel
and gaseous-fueled engines. The EEG system is a suitable replacement 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, and mechanical drives, to pumps or compressors.
With the use of GAC’s Quikest Display, the EEG requires no computer or Inter-
net connection. It is compatible with all GAC actuators and ATB’s, except the
ADB335 and ACB2001.

Overview

The EEG6500 Enhanced Electronic Governor is a digital governor designed to regulate engine speed in diesel and gaseous-fueled engines. It serves as a suitable replacement for mechanical governor systems requiring flexibility, precision, or accurate control of governed speed. The EEG6500 is specifically designed for industrial engine applications, including generator sets, mechanical drives, pumps, and compressors.

Function Description:

The EEG6500's primary function is to maintain precise engine speed. It offers both isochronous operation (maintaining a constant speed regardless of load) and droop governing (allowing speed to decrease slightly with increasing load), as well as variable speed control. The device integrates built-in fault protection with overcurrent sensing to safeguard the system. It also features an adjustable starting fuel strategy to reduce black smoke during startup and an extended speed range up to 12 KHz or 6000 RPM with frequency display. Speed ramping is supported for smooth transitions between idle, rated, or any other speed setting. For advanced applications, it includes a standard GAC AUX input for synchronizing and load sharing, J1939 engine data and speed output, and overspeed sensing and protection.

Important Technical Specifications:

  • Performance:
    • Isochronous Operation: ± 0.25% accuracy.
    • Speed Range / Governor: 100Hz - 12 KHz (200-6000 RPM with a 120-tooth flywheel) continuously.

    • Droop Range: 1 - 25% regulation.
    • Speed Trim: Programmable ±120 Hz.
  • Input/Output:

Usage Features:

The EEG6500 features an improved and simplified LCD user interface, allowing for fast setup with 5 push buttons and no potentiometers. This eliminates the need for a computer or internet connection when used with GAC's Quikset Display. Users can select between rated, idle, and variable speed settings, and choose between isochronous, droop, and variable governing modes. The system also supports speed ramping from idle to rated or any other speed setting.

The Quikset Menu provides access to various adjustable parameters such as OVER SPEED, #TEETH (number of teeth on the flywheel), CRANK (crank termination RPM), SPEED (fixed or droop operating speed), SPEED RAMP, V.SPEED (variable speed or trim), START FUEL (initial actuator position at cranking), DROOP%, LOCKED (manual/auto locking of display), FUEL RAMP, GAIN (proportional set point of PID control), IDLE (engine speed when idle input is closed), STABILITY (integral set point of PID control), FUEL LIM (maximum actuator percentage allowed), and DEADTIME (derivative set point of PID control).

The device includes a "Lock Feature" to prevent unauthorized changes to parameters. It also offers "OEM Save Settings" to copy current settings to a separate configuration area for later restoration, and "OEM Restore" to load these saved settings.

Maintenance Features:

The manual provides comprehensive troubleshooting guides for system inoperative conditions, instability (fast periodic, slow periodic, non-periodic), engine overspeeds, and situations where the actuator does not energize fully or the engine remains below desired governed speed. It includes electrical checks for battery supply voltage, speed sensor signal, and actuator output, along with probable causes and customer actions for various fault codes.

The EEG6500 also logs fault codes, including actuator overcurrent, loss of speed signal, overspeed, variable speed settings reversed, no potentiometer/signal detected, new/incompatible software loaded, and FLCU/NLCU setting invalid. These codes aid in diagnosing and resolving issues. The device's design, with vertical mounting preferred, facilitates the draining of fluids in moist environments, contributing to its longevity. Regular checks of actuator wiring, speed pickup, fuel system, and potentiometer wiring are recommended for maintenance.
