Control system for a cooking oven |
摘要 |
A control system and method of operating the control system are provided, the system having a supervisory circuit for detecting failure of the system and disabling a high energy control circuit of the system, the supervisory circuit having a capacitor therein for sustaining an on condition of a supervisory transistor that is in series with an output relay driver transistor of the high energy control circuit, and a temperature sensing unit that is disposed intermediate a microcomputer of the system and the supervisory circuit for continuing the charging of the capacitor only as long as the temperature sensing unit is sensing an output temperature effect of a heating unit of the system that is below a predetermined high temperature limit for the system and that terminates the charging of the capacitor when the sensed temperature is above the predetermined high temperature limit.
