External Diagnostic Message Display
Standard on all DIN-Rail safety light curtains is the "External Diagnostic Message Display"
Extensive Testing
The DIN-Rail safety light curtain incorporates extensive testing and burn-in to establish a high degree of product
reliability and safety.
Redundant Captive Contact Safety
Relays
Redundant relays assure safety if an output relay should fail. The DIN-Rail utilizes safety relays which have
force-guided contacts. This is a configuration where 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 "Relay Fault" will be
displayed on the diagnostic message display. The complete guarding system consists of two miniature pylons with a
controller for system diagnostics and wiring interface.
Alphanumeric Plain English Messages
Scrolling message display shows status and fault codes of the unit. This is an excellent safety and maintenance
feature which is unparalleled in the machine guarding industry for enhancing machine utilization.
Control Reliable System
Critical components of the DIN-Rail 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. The fault is then displayed on the message display.
Powerful Infrared Light Source
The DIN-Rail safety light curtain 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 DIN-Rail is highly immune to EMI, RFI,
and ambient light conditions and are unaffected by strobe lights and weld flash generated light sources.
