ことを特徴とする電子ガバナ用安全対策回路。In a diesel engine electronic governor that has an engine speed signal detector and an actuator that can stop the fuel supplied to the engine and stop the engine when no current is flowing, it is possible to detect changes in the starter signal when starting the diesel engine. A means for detecting whether the engine rotational speed signal after a certain period of time is within a predetermined range, and a means for cutting off the current flowing to the actuator in order to stop the engine if the signal is outside the range.
