The operator selects an engine speed by placing the engine speed dial in one of the ten positions. The controller will determine if the engine is operating at the speed that was selected by comparing the engine speed with the engine speed sensor. If the engine is not operating at the selected speed the controller activates the governor actuator which moves the governor lever. The controller uses the governor feedback sensor to place the governor lever in a position that corresponds to the selected engine speed. The governor actuator uses a cable(s) to rotate the pulley. If the pulley is rotated counterclockwise, the governor lever that is connected to the pulley will move in the accelerate direction. If the pulley is rotated clockwise, the governor lever will move in the decelerate direction.
