The Latest Safety Light Curtain From the Press-Guarding ExpertsWintriss has been building the Shadow light curtains for the toughest applications for more than 35 years. Our light curtains withstand the rigors of the pressroom, including severe shock, mechanical abuse, and lubricant spray. With more than 45,000 systems installed, the Shadow has a proven track record.
Optional Shadow 8 Control Box Features
Shadow 8 Heads Connect Directly to New WPC 1000 and WPC 2000 For press guarding applications, up to 4 pairs of Shadow 8 heads can connect directly to the new WPC 1000 and WPC 2000 Wintriss Clucth Brake Controls - with no need for a separate control box. This reduces both the initial investment in equipment and the cost of installation.
Connect up to Four Pairs of Heads to One Control Shadow 8'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 202” 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 110 feet).
Programmable Fixed BlankingFixed 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 switches on the control. Shadow 8 senses the presence of the object and “blanks” the obstructed beams. The Individual Beam Indicators (IBIs) light up to indicate which beams are blanked. When the object is removed, the system will not allow the machine to run until the control has been reprogrammed to “unblank” the beams. The first or the main segment must have a minimum of 7 to 9 consecutive beams (5.5” to 7”) not blanked based on its height (e.g., the 12” main segment must have 7 consecutive beams (5.5”) not blanked) and 2 consecutive beams in each extension must not be blanked.
Individual Beam Indicators (IBIs)
Floating Blanking WindowShadow 8 also enables you to set a floating blanking window, one beam wide, to allow objects smaller than 1”, 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 VerificationsInstead of saying “designed to meet”, at Wintriss we felt it was important to subject our systems to the toughest third party certifications. Shadow 8 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 8 complies with OSHA 1910.217, ANSI B11.1, ANSI B11.19, CSA Z142 and CSA Z432.
Helps You Comply with OSHA Lockout/TagoutShadow 8 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 SupportIt’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.
Shadow 8 heads are available in lengths from 12" to 59" (extensions from 9")
