Filed: 1989-01-11
Abstract: PURPOSE:To enable on-line detection by providing a 1st fault detecting means and a 2nd fault detecting means which decide whether the output signal levels of a low value selecting circuit and a high value selecting circuit exceed predetermined reference values or not. CONSTITUTION:If a transistor(TR) which constitutes the low value selecting circuit 5 short-circuits to become faulty, a voltage which is higher by the base- emitter voltage drop of the TR is developed at the emitter of the TR. Further, when the TR has an open-circuit fault, the emitter potential drops. If a diode short-circuits to become faulty in the high value selecting circuit 6, the output signal of the no-power-source type majority decision circuit becomes higher by the forward voltage of the diode. If the diode has an open-circuit fault, the potential on the anode side of the diode is as high as input signals E1-E3. For the purpose, the output signal of a circuit 5 which constitutes the no-power- source type majority decision circuit and the output signal out of the circuit 6 are compared with predetermined reference voltages V1-V7 to detect the fault of the no-power-source type majority decision circuit.
