The Ultimate in Safety-Quality-Value

N/A 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 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. 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.

External Diagnostic Display
Standard on all Triad safety light curtains is the "Quickview Diagnostic Display." The alphanumeric 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 unit’s self-checking circuitry recognizes the situation and initiates a safe stop of the machine.

Powerful Infrared Light Source
Triad safety light curtains 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 light curtains 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 light curtains incorporate extensive testing and burn-in to establish a high degree of product reliability and safety.

Quickview Diagnostic Display

N/A 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.

Subject Machine Control Reliability Requirements

N/A Control reliability control circuits shall be designed and constructed so that a single failure or fault within the system does not prevent the normal stopping action from being applied to the press when required or does not create an unintended stroking action but does prevent initiation of a successive stroke until the failure is corrected (ANSI B11.1-2001). Always refer to the specific ANSI or OSHA code for the complete requirements of the subject machine.

Light Curtain Options

N/A Auxiliary Output Contact: Provides an isolated (dry) contact output to be used as a signal line. Specify NO or NC output. Add suffix AO to light curtain Model Number.
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. Add suffix CI to light curtain Model Number.
External Relay Check: This option 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. Add suffix ER to light curtain Model Number.
Resettable Latching Relays: Requires the light curtain to be manually reset every time the light curtain is penetrated. Add suffix LR to light curtain Model Number.
24VDC Power Source: Add suffix DC to light curtain Model Number.


N/A The Triad infrared safety light curtain is suited for air clutch, hydraulic, and pneumatic equipment such as punch presses, mechanical, pneumatic and hydraulic press brakes, injection molding machines, die casting operations, powered metal compacting presses, filter presses, automatic assembly equipment, bending rolls, robotic operations, FMS systems, slitting lines and food processing machinery.

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.

Press Brakes
Triad SuperLight VI infrared light curtain now designed for power press brakes, utilizing the Floating Blank series.

How Floating Blank Works:

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 8cm based on 2cm increments.

Triad Controls
Triad Controls manufacturers a complete line of standard and customized machine guards and controls for safety and increased productivity. Control systems are control reliable and available in both solid state or relay logic. Controls meet or exceed OSHA regulation 1910.217 and ANSI standards B11.1-2001, B11.19-1990 for control reliability and component monitoring.

Muting Kit - Triad Package #130
Triad SuperLight VI barriers can be bypassed during non-hazardous portions of machine operation. Ideal for press operations where parts or scrap are being ejected or during hand removal of parts on the upstroke of the machine. Reference Triad Package #130 PB for Press Brakes. Always submit the machine electrical schematic for proper point of interface.

Robotic and Automation Multi-Sided Guarding System
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.

Blanking adjustments required when die heights change are not necessary. The Floating Blank light curtain automatically adjusts to the various feed positions providing production with protection. The Floating Blank light curtain adapts to mechanical, air clutch, and hydraulic press brakes.

Automatic Tripping - PSDI
Presence Sensing Device initiation Certification must be obtained for proper application of this optional feature. Refer to the specific OSHA or ANSI standard related to the subject machine on which PSDI is to be applied.
