Abstract
PURPOSE: To secure alarm issue regardless of mode by controlling an alarm device with a load driving relay coil and a thyristor connected to a transistor driven by each output of a flame detection circuit and a trial circuit.
CONSTITUTION: A load driving block A and a controlling circuit block B are isolated with a diode 12, and each load of a master valve 1, a pilot valve 2, a main valve 3 and an ignition transformer 4 in the block A is controlled by contacts XP2, XF1, XF2 of relays XP, XF which are controlled by the block B. A flame detection circuit 5 turns the relay XF ON where the pilot valve is ignited and OFF where it is not ignited according to an input from flame detection element 6. A prepurge trial timer circuit 7 turns a power switch 41 ON, turns a transistor 13 ON after a constant period of time and further turns the transistor 13 OFF after a constant period of time.
