Abstract

PURPOSE:To make it possible to decide whether the cause of a receiving fault exists in the receiver or in other, by applying a false signal to the receiver when the receiving fault occurs in the receiver. CONSTITUTION:In case that a receiving fault occurs in receiver 5, monitor controller 4 detects it to start false signal oscillator 2, and the false signal is sent to receiver 1 through coupling circuit 1. If the false signal applied to receiver 5 can be received by monitor unit 4 normally, receiver 5 is not faulty, and receiver 5 waits as it is because others are faulty. Thus, it can be decided whether the cause of the receiving fault exists in receiver 5 or not by applying the false signal to the receiver at a receiving fault time.
