Abstract
PURPOSE:To prevent the malfunction of a host equipment by preventing an origination to the host equipment even if the power source of an equipment which originates a warning only at the time of failure and the power source of an equipment which originates a warning at both cases of failure and power source turning off are turned off simultaneously when said two kinds of equipments exist together with each other. CONSTITUTION:The B equipment 2 has a b-contact al2 that closes at both cases of failure and power source turning off. The A equipment 1 has an a- contact al1 that closes at the case of failure and an a-contact rl that closes in delay only at the time of power source turning on by an opening/closing circuit 11 consisting of a transistor, a capacitor, and a resistor, etc. The contacting point al1 is connected in parallel with a serial circuit of the contacts al2 and the rl, and when either circuit is conductive, the warning is originated to the heat C-equipment 3. By such a constitution, even if the power sources of the equipments 1, 2 turn on/off, the serial circuit of contacts al2 and rl do not close, hence the warning signal is not originated to the equipment 3. As a result, the equipment 3 can be prevented from malfunctioning.
