Abstract

PURPOSE:To enable to have the output of simultaneous group busy monitor and simultaneous group closing, by leading in the closing leads of each register in one group unit. CONSTITUTION:If only No. 1 is busy and others are vacant among the incoming registers IR, at the points A and C of the contact mbo of the closing expansion tree, current flows to IR via the resistor of a high resistance value, the voltage at the points A and C is lower than that at the point X of the busy detection relay BY, it is cut off with the rectifier and no current flows. But, at the point B, since the B relay in IR is operated and the closing leads are cut off, the ground from the resistor connected to the line to the point B flows to the point X of BY to activate BY. Thus, the busy monitor for IR of the groups two or more is made simultaneously, and by inoperative BY, ground is delivered with the operation of the closing start relay MB, restoration of the busy discrimination relay, and restoration due to cut off of the contact mb of the busy detection circuit closing relay BCK to close IR of one group.
