Micro Guard light curtain by Pinnacle. Diverse Redundancy Design ConceptPinnacle safety light curtains utilize the diverse redundancy design concept. This gives the safety light system a higher level of redundancy and control reliability. The two microprocessors are of different design, and the microprocessor or parallel programs are run and made up from different instruction sets written by different programmers.Self-Checking CircuitryPinnacle safety light curtains self-check every 20 milliseconds. Self-checking is the ability to electronically verify that all of the systems critical internal circuit components and their redundant counterparts or back-ups are operating properly
