Abstract

PURPOSE:To make unnecessary special reset terminals, by taking an individual control signal as the inverting signal for the signal to be restored when the switch circuit is to be restored individually during the application of group restriction signal, and taking the switch circuit as it, if not during the group restriction. CONSTITUTION:An individual signal ''1'' is fed to a signal line l2 for the restoration instruction to a switch circuit 20. Further, the individual signal ''1'' is fed at a specific time, this individual signal is fed to the NOT input terminal of an AND circuit 22-1 to turn off the circuit 22-1 and the group restriction signal is not delivered to a DFF21. Further, ''0'' is output to an output terminal Q of FF21 and a universal access relay UAR10 is not activated. Further, contacts 10-1, 10-2 are restored as shown in Figure and the state of callout restriction is released.
