Abstract
PURPOSE: To provide a safety device for keeping a termination of operation of display lamp and equipment by a method wherein an abnormal signal is fed to a gate circuit of thyristor, an illumination of the display lamp and the termination of equipment may be performed and a characteristic of latching in the thyristor may be utilized.
CONSTITUTION: When an abnormal sensor circuit 3a (or 3b) senses an abnormal condition, a signal is fed from the abnormal condition sensing circuit 3a (3b) to the gate circuit 6a (6b) of the thyristor 4a (4b), resulting in causing the thyristor 4a (4b) to be conducted, an electric current is flowed from DC power supply 1 to a light emitting diode 2a (2b), resistor 5a (5b), thyristor 4a (4b) to cause the light emitting diode 2a (2b) to be lit. The control circuit senses a conversion from a high level to a low level in the diode 7a (7b) and an operation of the combustion equipment is terminated. Said condition may be kept by setting the resistors 5a, 5b more than a holding current of the thyristor.
