摘要： PURPOSE:To improve reliability by preventing malfunction by disconnecting a precedent interlocking lead line from the other electrode of a control power source through the operation of the selection relay of some stage. CONSTITUTION:When a push-button switch P13 for setting is depressed after a power switch S is turned on, a relay R0 for setting is energized and the selection relay R1 of the 1st terminal equipment holds itself in readiness for operation. Then, one input pulse is supplied to a ratchet relay F to change a contact F1 over to the side of a terminal (a), and the selection relay R1 operates. In this case, it holds itself as it is, and a contact R13 permits the selection relay R2 of the 2nd terminal equipment of a next stage to prepare for operation; and a relay R0 for setting is unenergized by opening a contact R12 with slight delay behind the operation of the selection relay R1. The selection of the 1st terminal equipment closes a contact R14, which is confirmed by a center part CS.
