If sensing or timing circuit occur more (falling) Guo Di circle abnormal failure (as thermistor NTC61 opens a way or resistance R61, R62 short circuit or timing capacitor C61 short circuit) time, its dividing point (V t6) voltage holds V close to circuit -current potential, through resistance R618 lifting slightly, makes the input of operational amplifier A 61, A62 and A63, A64 contact (total input end V of two element circuits altogether i6) on input current potential also extremely low, less-than operation amplifier A62, A63 two output terminal (V o61, V o62) electronegative potential, through voltage stabilizing diode DW63 to operational amplifier A 61 positive (+) input end pad planted agent circle (limit), this end circle (limit) current potential is a little more than input end (V i6) current potential, make output terminal (V c61) exporting noble potential, triode VT61 ends; Output terminal V o62electronegative potential, through voltage stabilizing diode DW64 to operational amplifier A 64 anti-phase (-) input end pad planted agent circle (limit), this end circle (limit) current potential is higher than input end (V i6) current potential, make output terminal (V c62) export electronegative potential, drag down anti-phase (-) input end current potential of operational amplifier A 62, A63 on the one hand through diode D64 and resistance R616 feedback, make spacing setting hold V m6spacing is lower limit, on the other hand triode VT62 is ended, forces relay J 6 coil blackout to discharge, and its normally opened contact cuts off load power source, reaches the object preventing circuit system out of control, ensure that security control.Fall LED 61 at end protection display circuit (7) simultaneously, LED62 is luminous, display is crossed the border and is protected supervisory circuit (operational amplifier A 61, A64) to be in emergency protection state of a control.
If when top circle (thermistor NTC61 short circuit or resistance R61 open a way or timing capacitor C61 open circuit) fault crossed by sensing circuit, input end V i6current potential is close to V + 1terminal voltage, output terminal (V o61, V o62) current potential is also high, close to power supply V + 2terminal voltage, makes operational amplifier A 61 positive (+) input end current potential higher than its anti-phase (-) input end (V i6) current potential, output terminal (V c61) export noble potential, and operational amplifier A 64 anti-phase (-) input end current potential is higher than its positive (+) input end (V i6) current potential, output terminal (V c62) exporting electronegative potential, triode VT61, VT62 are ended simultaneously, forces relay J 6 power-off to discharge, its normally opened contact cuts off load power source, reaches and prevents object out of control, ensure that security control.
When circuit generation input and output side itself opens a way unsettled fault, this circuit also prevents effect out of control.
Visible, the present embodiment has anti-ability out of control comprehensively, is that one did not lose efficacy when various abnormal failure, can guarantee the exception peace control universal circuit of normal safe stability contorting.
