Abstract
PURPOSE:To avoid impairing the adaptation to a fault arisen at a slave station, by installing a main circuit and an auxiliary circuit between a fault information transfer device and a fault information receiver as the fault information transfer circuits. CONSTITUTION:Both a main circuit and an auxiliary circuit are installed between a maintenance station including a fault information transfer device ALSND and a slave station including a fault information receiver ALRCV as the fault transfer circuits. At the same time, a relay SUP is provided to detect a fault of the circuit along with a relay switch SW that performs an automatic changeover from the faulty circuit to the auxiliary circuit when a circuit fault arises. Thus the main circuit, if its fault is detected, is automatically changed over to the auxiliary circuit in both devices ALSND and ALRCV to secure the fault information transfer circuit. Thus the adaptation is assured for a fault arisen at the slave station.
