Abstract

PURPOSE: To stop operation of starter and prevent rotation of the starter at an overspeed, by controlling a starter power source disconnecting circuit with the output of a detection circuit for detecting the output level of a D-A converting circuit, which detection circuit is provided between the D-A converting circuit and starter disconnecting circuit.
CONSTITUTION: When the starter switch is turned ON, starter relay 3R is energized by the output of comparator COP and contact SW1 is closed, whereby current is supplied to starter 4 and engine 1 is started. As rotational speed of engine 1 is increased, oscillation frequency of pulse generator 5 is also increased, whereby voltage of operational amplifier OP in D-A converting circuit 6 is amplified and supplied to level detector 8 and its output potential is raised. By this potential, output of comparator COP is reduced to zero, when the engine is rotated at a speed lower than the idling speed but higher than the minimum starting speed. As the result, current supply to starter disconnecting circuit 3 is stopped and operation of the starter is stopped
