Abstract
PURPOSE: To prevent the generation of a hazardous condition by a method wherein a low voltage detecting circuit is provided, and in case the load for a combustion control circuit turns excessive, or short-circuitted due to the lowering of power voltage, misconnection or the like the power source for the combustion control circuit is shut off.
CONSTITUTION: In case when a supply voltage drops due to some abnormity, or the load of a combustion control circuit is overloaded or is short-circuited, a control circuit current source drops to operate a low-voltage circuit. Then, a supply source of a combustion control circuit 6 is shut off, and at the same time an instant actuation of the low-voltage circuit is made at the rise-up time of switching which makes the supply source actuation retard by a capacitor 19, and at the same time a low- voltage circuit does not work at switching the supply source On with the help of a transistor 23 which works by a differentiation circuit generating a trigger signal when the supply source is made ON.
