Dual Redundancy Design Concept
The SLT Series safety light curtain utilizes the dual redundancy design concept. This gives the safety light system a high level of redundancy and control reliability.

Self-Checking Circuitry
The SLT Series safety light curtain self-checks every 20 milliseconds. Self-checking is the ability to electronically verify that all of the system’s critical internal circuit components and their redundant counterparts or back-ups are operating properly.

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.

Redundant Captive Contact Safety Relays
Redundant relays assure safety if an output relay should fail. The SLT Series 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 fault, a Code 5 or 6 will be displayed on the diagnostic display.

External Diagnostic Display
Standard on the SLT Series safety light curtain is the "Quickview Diagnostic Display”–an alphanumeric display showing status and fault codes of the unit (an excellent safety and maintenance feature).

Control Reliable System
Critical components of the SLT Series 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 machine.

Powerful Infrared Light Source
The SLT Series utilizes 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 shutdowns caused by dirt, coolants, lubrication mists, and machine oils. The SLT Series is highly immune to EMI, RFI, ambient light conditions, and are unaffected by strobe lights and weld flash generated light sources.

Extensive Testing
The SLT Series incorporates extensive testing and burn-in to establish a high degree of product reliability and safety.
