Electronic Governor System

The engine electronic governor system allows for improved control and increased generator performance compared to mechanically governed systems. The result is smooth TUFBEZTUBUFPQFSBUJPOXJUIPVUUIFiIVOUJOHwDPNNPOUP many mechanical governors. The system also reduces speed variations under engine loading and unloading and significantly reduces frequency fluctuation experienced when the engine is under higher loads.

The electronic governor system is composed of a stepper motor (B), stepper motor throttle control linkages (C), and throttle side linkage (A). The control board contains a digital controller that processes engine speed information and sends appropriate commands to the stepper motor to control the position of the engine throttle.

Since the electronic governing system controls the engine

While trouble shooting any of these conditions, a verification of the electronic governor system can be initiated through the control panel – advanced menu options – Electronic Governor Check.

Electronic Governing Check:

 

 

The generator has an electronic governing check feature that

 

 

will turn on the stepper motor and move the throttle linkage

 

 

clockwise and counterclockwise within the throttle limits.

 

 

The test will rotate the stepper motor and move the throttle

 

 

arm between the wide open throttle and dead idle limits 4

 

 

times with a 2 second delay between each throttle sweep.

 

 

This will allow visual verification that the stepper motor is

functioning properly and the control linkages are connected.

 

 

The engine will not attempt to start during this test. If the

 

 

stepper motor does not move, or if a linkage binds, then

 

 

service may be required.

 

 

NOTICE If stepper motor does not move, please make sure the stepper motor connector is attached.
