ABSTRACT:
A top gas burner control employs touch keypads to provide operator input signals to a microcomputer. The microcomputer controls reversible gear motor to operate gas burner valves, and the positions of the shafts of the valves are fed back to the microcomputer via decoders. The initial operation of a burner requires the operator to touch and ON keypad, in response to which the microcomputer rotates the shaft of the valve to a maximum open position and energizes an igniter at this position. The operator must the touch a further keypad within a predetermined time in order to prevent the microprocessor from closing the valve.
