EDG5500
Electronic Digital Governor
With Quikset Display
INTRODUCTION
1
GAC’s EDG5500 digital governor is designed to regulate engine speed on diesel
and gaseous-fueled engines. The EDG system is a suitable replacement for any
mechanical governor system that needs flexibility, precision, or accurate control
of governed speed. The EDG is designed for industrial engine applications from
generator sets, and mechanical drives, to pumps or compressors.
Computer
With the use of GAC’s Quikset Display, the EDG5500 requires no computer or
internet connection.

• Wires must be twisted and/or shielded for their entire length
(14 turns per foot)
• Gap between speed sensor and gear teeth should not be smaller
than 0.02 in. (.51mm)
• Speed sensor voltage should be at least 1VAC RMS during crank
WARNING Loss of Magnetic Pickup Sensing
If the EDG5500 detects no input from the magnetic pickup,
the EDG will set the actuator to 0V and set the speed to 0
RPM. After the EDG has detected loss of magnetic pickup,
the display will flash the RPM along with the Warning Indicator. Parameters will be unchangeable.
