Diverse Redundancy Design Concept
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
TRIAD 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
Redundant Captive Contact Safety
Redundant relays assure safety if an output relay should fail. SuperLight VI utilizes
safety relays which have force-guided contacts. The contacts are mechanically locked together so that if one set of
contacts weld, the other contacts cannot change state. If one should fail, code 5-6 will be displayed on the
Extra Safe Design
Provides two methods of
fail-safe design. One utilizes two microprocessors and two captive contact relays, and one uses four watchdog
timers monitoring the system and the captive contact relays.
External Diagnostic Display
Standard on all
TRIAD safety lights is the "Quickview Diagnostic Display." Alpha-numeric display shows status and fault codes of
the unit. This is an excellent safety and maintenance feature.
Control Reliable System
of the SuperLight VI are duplicated so that a single component failure will not cause an unsafe condition. If a
component does fail, the units self-checking circuitry recognizes the situation and initiates a safe stop of the
Powerful Infrared Light Source
lights utilize powerful, safe, and predictable infrared light as its sensing source. This gives the system greater
reliability and enhances machine utilization by minimizing nuisance trips and shutdowms caused by dirt, coolants,
lubrication mists and machine oils. TRIAD safety lights are highly immune to EMI, RFI, and ambient light conditions
and are unaffected by strobe lights and weld flash generated light sources.
TRIAD safety lights
incorporate extensive testing and burn-in to establish a high degree of product reliability and safety.
