Connect up to Four Pairs of Heads to One Control
Shadow VII’s unique design enables you to protect multiple sides of a machine using a single control, one pair of cables, and up to 4 pairs of light curtains in series.   You can protect both the front and back of your equipment as well as provide horizontal pass-through detection.   Even a large machine can be guarded with up to 96” of protected zone to a single control providing an economical solution and minimizing installation time (for either the transmitter or receiver, the total length of the heads and interconnect cabling cannot exceed 50 feet).

Programmable Fixed Blanking
Fixed blanking windows disable one or more beams to allow stationary objects such as conveyors or work tables to remain in the sensing field.   You simply place the obstruction between the transmitter and receiver and turn the key-lock switch on the control to the program position.   Shadow VII senses the presence of the object and “blanks” the obstructed beams.   When the object is removed, the system will not allow the machine to run until the control has been reprogrammed to “unblank” the beams.

Floating Blanking Windows
Shadow VII also enables you to set a floating blanking window, one or two beams wide, to allow objects smaller than 1” (1 beam) or 1.9” (2 beams), such as air-ejected parts, to pass through the light curtain in a random pattern without interrupting operation. This can also be useful when air or hydraulic lines need to pass through the field. You can use both floating and fixed blanking simultaneously.

3rd Party Verifications
Instead of saying “designed to meet”, at Wintriss we felt it was important to subject our systems to the toughest third party certifications.   Shadow VII has undergone independent testing and certifications by Underwriters Laboratories (NRTL/C) to CAN/CSA 22.2 No. 14 and CAN/CSA 22.2 No. 0.8 and by TÜV to Category 4 CE/IEC 61496-1 and CE/IEC 61496-2.   Shadow VII complies with OSHA 1910.217, ANSI B11.1, ANSI B11.19, CSA Z142 and CSA Z432.

Helps You Comply with OSHA Lockout/Tagout
Shadow VII light curtains can eliminate the need to lockout/tagout during die changes.   OSHA regulation 1910.147 states that lockout is not required when the activity is “routine and integral to production and personnel are protected by other guarding methods.”

Service And Support
It’s necessary to have a thorough understanding of the various safety regulations when applying a safety light curtain system in your application. Both factory personnel and our representatives keep up with these changes.   At your request we will check out your application and make recommendations for the proper light curtain configuration as well as any supplemental guarding that may be required.   All of our light curtain systems carry a 2-year warranty.   If a system does go down, we have a 48-hour turnaround policy on repairs.
