Abstract
PURPOSE: For effective working of fail safe function, to cut off the base current of holding transistors connected in parallel to the output transistor of a timer circuit when flame is detected.
CONSTITUTION: When flame has extinguished during normal combustion operation, a transistor Trl turns on and a transistor Tr2 turns off since a flame detecting circuit detects no flame. Then, a relay XF is reset, a transistor Tr4 turns off, an igniting relay XF is reset also. Ignition operation is made again. Further, when said flame detecting circuit has come on danger side, i.e. said relay XF has come in such a direction as to turn on, upon power supply, said transistor Tr2 turns on to short a condenser C2 through the medium of a resistor R7 and a diode D2. Even through the elapse of time, PUT does not turn on, and prepurge operation is made continuously.
