SuperLight VI Programmable Safety Light Curtain

Please choose from the features below to see if the SuperLight VI Programmable Safety Light Curtain is right for your application:

Diverse Redundancy Design Concept TRIAD 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 Circuitry 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 properly.

Redundant Captive Contact Safety Relays 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 diagnostic display.

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 Critical components 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 machine.

Powerful Infrared Light Source TRIAD safety 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 shutdowns 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.

Extensive Testing TRIAD safety lights incorporate extensive testing and burn-in to establish a high degree of product reliability and safety.

Standard on all Triad safety light curtains is the revolutionary front panel diagnostic display. The bright red alphanumeric LED display shows the status of the safety light curtain along with various integral fault codes relating to the maintenance and operation of the system. The diagnostic display monitors microprocessors, captive contact safety relays, bad grounds, external infrared sources, shorts, blanking, etc. Fault conditions are easily read and displayed on the top front panel of the receiver pylon. These easy to read external diagnostic codes and status displays will enhance safety and machine utilization by minimizing machine downtime and set-up time measurably The advanced design of the SuperLight VI diagnostics will also count and display the number of beams blanked out in the “Auto-Blank” mode. This is an important feature when computing the depth penetration factor required for proper installation. A detailed definition, status, reason(s), and cure listing is provided within the installation and operation manual of each Triad safety light curtain.
Triad’s advanced “Auto-Blank” option is unique because it will automatically blank out only the required number of beams needed to accept an obstruction such as a conveyor, bracket or fixture. The unit is easily programmed by a supervisory controlled four position keyed selector switch located on the front panel of the receiver pylon.The “Auto-Blank” method of blanking is much safer than DIP switch or master/slave blanking systems because only the area of the obstruction will be blanked. This feature prohibits unsafe oversizing of the blanked area commonly found throughout industry on manually blanked systems. “Auto- Blank” also eliminates the need to count beams and to locate where and what beams are to be shut off to obtain the correct beam elevation to accept an obstruction. “Auto-Blank” will also watch the obstruction and, if it moves or is removed, will go into a “machine stop mode” to prevent further machine operation. This is an additional safety feature not available on manually blanked units. These features truly enhance production while providing the ultimate in safety.  

When the key switch is turned to the “Auto-Blank” function, the “Quickview Diagnostic Display” will show the number of blocked beams for two seconds, then verify that the obstruction is being monitored. This is required information for the depth penetration factor and for proper installation of any safety light curtain.

  The versatile “Auto-Blank” (AB) Blanking Series includes:  • Constant scan light curtain  • One Beam Floating Blank built-in plus “Auto-Blank” capability  • Two “Auto-Blank” Modes – up to 8 beams blanked but need not be sequential 
A. One “Auto-Blank” mode with keyed reset when guarded zone is penetrated  B. One “Auto-Blank” mode with automatic reset when guarded zone is penetrated
The “Floating Blank” option provides the flexibility necessary to effectively guard all types of equipment that require multiple floating beams. This is quite common in the fabricating industry where the workpiece moves. The “Floating Blank” permits work pieces to be formed vertically or horizontally through the guarded area without shutting down the machine. Entry into the protected area by the operator or passerby will prevent the start or, if the machine is in motion, will provide a signal to stop the machine. The “Floating Blank” is controlled by a keyed selector switch that will allow a work opening of 8 cm based on 2 cm increments (shown above). Blanking adjustments required when die heights change are not necessary. The “Floating Blank” light curtain automatically adjusts to the various feed positions providing protection with production.

Swing Mount Brackets (Model 9000)

Excellent method of mounting the light guard for press brakes or when the light guard is to be moved for die set-ups or machine maintenance. The Model 9000 consists of three 180 degree pivot points along with the light curtain’s diagonal movement capability for virtually unlimited light curtain positioning. Two inch square tubing (3/16″ thick) painted OSHA yellow which mounts directly onto the machine housing and makes for a heavy duty, yet versatile mounting bracket.

AO -Auxiliary Output Contact: Provides an isolated (dry) contact output to be used as a signal line. Specify N.O. or N.C. output.

CI – Cincinnati Interface/Forced Interrupt: Allows an external device (i.e., Cincinnati Press or PLC) to initiate a red condition on the light curtain. This option is required on machines that feed a 24VDC signal back to the safety light curtain to assure that the safety control circuit can be shut down.

ER – External Relay Check–monitors the control relays of the guarded machine to assure that the machine control relays change state when the safety light curtain sends a stop signal.

LR – Resettable Latching Relays–requires the light curtain to be manually reset every time the light curtain is penetrated. Useful option when the safety light curtain is used for perimeter zone guarding.

DC – 24VDC Power–Required when light curtain is powered by 24VDC instead of 120VAC.

LGB – Light Guard Bypass–On/off key switch with indicator bulb used to bypass the output relays in the light curtain.

Punch Presses The SuperLight VI is designed to accept coil stock movement with no press shutdowns or adjustments to light guard. No adjustments necessary to light guard for die height changes or changes from automatic to hand fed secondary operations. Robotic and Automation Multi-Sided Guarding Systems Easily installed cornering mirrors combined with the easy alignment characteristics of the SuperLight VI provide multi-sided protection which allows complete visibility and access to the protected pinch point or hazardous zone for a fraction of the cost of physical barriers. Press Brakes The Triad FLOATING BLANK light curtain provides the flexibility necessary to effectively guard all types of power press brakes. The FLOATING BLANK permits work pieces to be formed vertically or horizontally through the guarded area without shutting down the machine. Entry into the protected area by the operator or passerby will prevent the start, or if the machine is in motion will provide a signal to stop the machine. While other safety devices must be altered to allow materials to feed through, the FLOATING BLANK is controlled by a keyed selector switch that will allow a work opening of up to 8 cm based on 2 cm increments. Blanking adjustments required when die heights change are not necessary. The FLOATING BLANK light curtain automatically adjusts to the various feed positions providing protection with production. The FLOATING BLANK light curtain adapts to mechanical, air clutch, and hydraulic press brakes.
