EEG7500 Enhanced Electric Governor   8-2021-A8      PIB5115

The GAConfig Tool allows settings in the tool to be stored, shared, and 

imported back into the tool for use on multiple EEG7500 units.  Settings 

can be exported at any time while using the GAConfig Tool. It is also 

useful if you change actuator types often, allowing you to save settings 

and import settings as you must restart the EEG7500 unit to change 

Operating mode. 

To Export Files:

1. 

EEG7500 must be turned on and the GAConfig Tool must be 

running on the PC. 

2. 

At the Tool bar click the Export button. The windows file explorer 

displays. Drill down to the file location where you want to save the 

file.

3.  Rename the default file name to something better suited for your 

use. 

4.  Click Save. Record the file location. 

To Import files:

1. 

EEG7500 must be turned on and the GAConfig Tool must be 

running on the PC. 

2. 

At the Tool bar click the Import button. The windows file explorer 

displays. 

3.  Locate the file you want to use and click on the name. 
4. 

Click Open. Click OK when complete.  

Best practice is to export GAConfig Tool information on a regular basis, 

monthly at a minimum.  Name the file with dates and intended use as 

part of the file name.  These files can also be shared with the GAC 

support team to aid in producing the best results. 

auxiliary Input

 (Terminal 8) enables connections to synchronizing and load sharing equipment.  AUX / Load Sharing in the GAConfig 

Tool allows the adjustment of the speed requests through the auxiliary input voltage, accepting a ± 5 V Nominal, 0 - 10 V DC and 

selectable response polarity.  In response the EEG can increase or decrease voltage to maintain constant engine speed.  Accessories 

tied to Aux must be shielded. 

Light force Governing

 provides finer adjustment resolution for smaller actuators. It is designed to work with low current small actuators, 

like T1 ATB, ALR/ALN, 100/103/104 series and normally closed Cummins EFC actuators.  Select the 

Light force Governing 

block

 

in the 

PID Tuning

 

block

 

when using small actuators to improve adjustments as they respond very quickly to input changes over a smaller range 

of operating current, using a fraction of the PID and current output of a normal actuator.  

Lead circuit 

(default is ON) enables the governor to be more responsive and typically increases the range of gain adjustment. This func

-

tion allows for more active control to increase the performance in typically slow engines. 

Speed Trim control

 is used with a potentiometer (or voltage input for certain units) to vary the engine speed remotely.

Idle

 is part of the Speed 1 setting and is set in one of the speed control settings on the Engine Tuning menu.  

Start fuel

 is an adjustment in the Engine Tuning menu. Start Fuel sets the actuator % applied during crank to control visible exhaust 

smoke.
