Electronic governor overview
The engines are tted with both mechanical and electronic governors. The electronic governor controls the
engine speed within ±0.25%.
If the electronic governor fails, the mechanical governor will control the maximum engine speed to 2050 rev/
min.
The electronic governor is made up of three parts:
The engine speed controller is set at the factory or can be adjusted using a laptop computer and data link.
The actuator - This is tted to the fuel injection pump and controls the engine speed.
The electro-magnetic sensor - This is tted to the ywheel housing and measures the engine speed.
Caution: Ensure that the electro-magnetic sensor is set correctly, and the cables are connected in accordance
with the wiring diagram. Ensure that there is electrical continuity between the frame for the engine and the
frame for the control panel.
