ABSTRACT:
A respective bus monitor circuit is connected to each group of a plurality of circuits selectively connectable to one end of a multi-conductor bus which extends to a common control circuit. When the function to be performed by the common control circuit is not completed within a preset time, all bus monitor circuits are signalled to check the group of circuits to which they are individually connected to locate a possible malfunction therein and automatically disable that group to prevent lock-up of the system if the malfunction is detected.
