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.

An overspeed shutdown device, independent of the governor
system, should be provided to prevent loss of engine control
which may cause personal injury or equipment damage. Do not rely exclusively
on the governor system electric actuator to prevent overspeed. A secondary
shutoff device, such as a fuel solenoid must be used.

8ADJUSTING FOR STABILITY
GAIN - RATED SPEED & IDLE SPEED
Once the engine is running at operating speed and at no load, the following
governor performance adjustments can be made to increase engine stability.
GAIN TYPE ADJUSTMENT PROCEDURE
RATED SPEED 1. Selected when IDLE input is disconnected.
The EEG6500 is equipped with two separate gains, one for rated
speed, the other for idle speed. Both are set using the GAIN set-
ting on the Quikset menu.

PARAMETER ADJUSTMENT PROCEDURE

1.
2.
3.
4.
Increase this parameter until instability develops.
Then, gradually decrease this parameter until stability returns.
Finally, decrease this parameter one increment further to ensure
stable performance.
If instability persists, adjust the next parameter.
B. STABILITY 1.
2.
Follow the same adjustment procedure as the GAIN parameter.
If instability persists, adjust the next parameter.
C. DEADTIME 1. If fast instability occurs, switch DEADTIME to low and repeat
steps A & B.
Normally, adjustments made at no load achieve satisfactory per-
formance. For further performance, refer to sections (10) & (11).
NOTE
EEG6500 - Variable Speed Response to External Voltage Input
Variable Speed Parameter (VSPD)- ‘ON’
After the initial set up is completed and the # of Teeth, Crank Termination
Speed and Rated Speed are set, position the external switch connecting
terminals ‘H’ and ‘K’ on to activate the DROOP mode following these sequence
steps.
1. Go to the Advanced menu: Press and hold all three buttons simultaneous-
ly for two seconds to switch to Advanced Menu.
2. Confirm that the VSPD (Variable Speed / Fixed Speed Control) is off.
Default position is off.
3. Confirm that the LEAD circuit is off. Default position is ON.
4. Set the NLCU (No Load Current) to the measured / displayed current
value when operating at no load rated speed (default value is 0.5 amps.)
5. Set the FLCU (Full Load Current) to the measured / displayed current
value when operating at full load rated speed (default value is 4.0 amps.)
6. Return to the Main Menu: Press and hold all three buttons simultaneously
for two seconds to switch to the Main Menu.
7. Select and set DROOP to the desired percentage.
8. Change the Speed parameter, which turns into the ‘DROOP OFFSET’.
This sets the RPM, above operating speed, to which the system will be
commanded when DROOP is enabled. This is an offset value.
1500 RPM operating speed x 0.05 (5.0% droop) = 75 RPM
Input 75 RPM, this is the offset value.
The NLCU entered must be less than the FLCU and the differnece between
the two must be at least 0.5A. If an invalid combination is entered a warning
will be flagged and the parameters will be default to 0.5A and 4.0A.

EEG6500 Enhanced Electronic Governor 05.09.18 PIB 5010 F
LIGHT FORCE GOVERNOR
Turning the “Light Force Governor”, (LFG) feature ‘ON’ (default is ‘OFF’) scales
the governor’s proportional response (GAIN) for the best resolution when
controlling small actuators, like the T1 ATB, ALR/ALN, 100/103/104 series and
normally closed Cummins EFC actuators. Turn the LFG feature “ON” for use
with these low current actuators. The letters “LFG” will be displayed in place of
the Primary Parameter Units when adjusting GAIN and STABILITY to indicate
the feature is ON. The LFG Feature can only be be turned ON or OFF when
the engine is not running.
LEAD CIRCUIT
Turning the “Lead Circuit” (LEAD) ON (default is ON) enables the governor to
be more responsive and typically increases the range of GAIN adjustement.
Turn Lead Circuit ‘ON’ when there is slow or moderate hunting at higher GAIN
settings.
OEM SAVE SETTINGS
OEM
OEM SAVE copies the currently active settings into separate OEM configuration area that can be restored at later date.
OEM RESTORE copies the settings stored from the OEM configuration area into the current settings and saves them for next power up. After restoration, unit
must be repowered to start engine.
OEM RESTORE
FACTORY RESTORE
OEM RESTORE
FACTORY RESTORE
Factory Restore loads the default settings as shipped from GAC into the current settings and saves them for next power up. After restoration, unit must be re-
powered to start engine. Factory Restore can only be done during power up.

INSTABILITY
INSTABILITY SYMPTOM PROBABLE CAUSE OF ABNORMAL READING
Fast Periodic
The engine seems to jitter with
a 3Hz or faster irregularity of
speed.
1.
2.
Readjust the GAIN and STABILITY for optimum control.
In extreme cases, change the DEADTIME parameter.
Slow Periodic Speed irregularity below 3Hz.
(Sometimes severe)
1.
2.
Check fuel system linkage during engine operation for:
a. binding
b. high friction
c. poor linkage
DEADTIME Parameter set too high.
Non-Periodic Erratic Engine Behavior
1. Increasing the GAIN should reduce the instability but not totally correct it. If this is the case, there is most
likely a problem with the engine itself.
Check for:
a. engine mis-firings
b. an erratic fuel system
c. load changes on the generator set voltage regulator.
If unsuccessful in solving instability, contact GAC for assistance.
[e-mail] or call: 1-413-233-1888
13 SYSTEM TROUBLESHOOTING
If the engine governing system does not function, the fault may be determined by performing the voltage tests described in Steps 1 through 3. Positive (+) and negative (-) refer to meter
polarity. Should normal values be indicated during troubleshooting steps, then the fault may be with the actuator or the wiring to the actuator. Tests are performed with battery power on and
the engine off, except where noted. See actuator publication for testing procedure on the actuator.
