Abstract

PURPOSE: In place of a safety switch which has been indispensable for a combustion controller, to use a flame detecting circuit and a timer circuit for controlling relay contacts thereby to make it possible to carry out a safe combustion operation and an alarm indicating operation.
CONSTITUTION: When a power source switch Sw is turned on, a relay Xp is turned on together with a transistor Tr2 after the ignition stand-by time. When the relay Xp is turned on, a constantly open contact Xp1 is closed, and hence a pilot valve switch PV is opened and an igniter IG operates, thus the ignition operation being carried out. In the case where the ignition action does not occur within this trial time, the relay Xp is turned off, and the constantly open contact Xp1 is opened, a pilot valve switch PV, and an igniter IG are turned off. While a relay XH is not turned off, a constantly close Xp3 is restored to a closed state together with a relay Xp. As a result, an alarm circuit AL receives a current supply through contacts XH2 and Xp3 and issues an alarm of ignition failure.
