Abstract
PURPOSE: To secure the safety for the entire system by adding the function to give the starting command simultaneously to several units of apparatus and thus realizing the simultaneous and parallel operation for n-units of apparatus as well as inhibiting the restarting at the recovery time of the faulty apparatus.
CONSTITUTION: With application of the starting command to K-units of apparatus, the number of the apparatus operating by the starting command is memorized 10. And each contactor is energized by the contact operation of the memory element to start K-units of apparatus. In case some operating apparatus has a fault, the fualt detector element of the apparatus operates to deenergize the contactor of the faulty apparatus. At the same time, (n - K)-units of auxiliary apparatus are backed up in the prescribed order by energizing the contactors of them, and the apparatus are reset not to be restarted immediately when the faulty apparatus is recovered.
