Resistance between 3 and Ground should be 300 to 1200 Ω. See
your specific magnetic pickup data for resistance settings. This
could be a defective speed sensor.

Slow Periodic
An irregularity of speed below 3 Hz.
(Sometimes severe)
1. Adjust P, I, and D
2. Check fuel system linkage during engine operation for:
•
binding
•
high friction
•
poor linkage
3. Add a small amount of droop.
Non-Periodic
Erratic Engine Behavior
Increasing Stability reduces instability but does not totally correct it.
If this is the case, there is most likely a problem with the engine itself.
Check for:
•
engine mis-firings
•
erratic fuel system
•
load changes on the generator set voltage regulator
If the GAConfig Tool is not connecting check the following on your PC or Laptop:
1.
Open the GAConfig Tool.
2.
Click Connect. The Select Serial Port window displays. Click Advanced Configuration arrow.
3. Select the number of the serial port the EEG7000 is plugged into. If no serial ports display call your
GAC representative.
4.
Check to make sure your baud rate is set to 19200 and all other settings are as show in this example.
5. If you made changes reboot the machine and try again.
6. If reboot does not see the EEG7000 please call your GAC representative.
EEG7000 SYSTEm TROUBlEShOOTING
17
If the engine governing system does not function determine the fault using the following voltage tests as 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 actuator wiring.
•
Perform test with battery power on and engine off, except where noted.
•
See your actuator model’s product bulletin for more information on testing the actuator.
