<p>PURPOSE: To provide an electric fault controller to dissolve a danger of melting the electric contacts in the power circuit of a receiver. CONSTITUTION: This failure controller 10 is equipped with an operation mechanism of an electric contact 11. This mechanism is activated by an electromagnet 14. A measuring and processing device 18, composed so as to measure impedance across the terminals of the power circuit R of a receiver 15, is connected between the power circuit of the receiver 15 and a return power circuit. This device 18 is connected to a contact 19 in a control circuit C. This contact 19 is constituted so as to shut down the power supply to the control circuit C, in the case that the power circuit R of the receiver 15 is short-circuited.</p> |
