Abstract
PURPOSE: To shorten timing, by providing plural numbers of timer, used in short timing, in series at sequence having long timing.
CONSTITUTION: In the case when firing failure as well get trouble on a timer 3 or gates connected with the timer, but not stop running, TFF (T flip flop) 17 is changed its condition in "1", by expiration of the 2nd safety time which is formed by the 2nd safety timer 4 connected with the timer 3 through a change-over circuit 20 consisted of NAND gates 21, 22 and 23, consequently an ignition device which is connected with terminal 50 through inverter 67, NAND gates 73, 68, and fuel supply divice which ic connected with terminal 51, are stopped. The 1st safety time controlled by timer 3 is got from TFF 13 located at 3rd steps from reference timer 2, but the 2nd safety time is got from TFF 17, consequently the 2nd safety time is longer than the 1st safety time.
