PURPOSE:To enable correspondence to new failure, by transmitting the occurrence of failure to the master station every time when a failure is taken place to the slave stations. CONSTITUTION:When a failure is taken place at a slave station, the failure monitor point x is closed. When the failure monitor point x0 is closed, ground is fed to the failure transfer start relay ST through the contact a0 of the relay A0 and blocking diode D0 to activate and hold the relay ST. The relay A0 is operated through the contact st and it is self-held during the continuity of failure. After the delivery circuit DV receives the start signal from the relay ST and transfers the content of failure to the master station, the transfer end display relay END is operated to restore the relay ST by cutting of the self-hold circuit of it and to enter the new failure reception state. Accordingly, every time when a new failure is taken place, failure can be transferred. |
