Wintriss Shadow® Series Safety Light Curtains

The Shadow® 8 is the latest safety light curtain from the Wintriss. Wintriss has been building the Shadow® light curtains for the toughest applications for more than 30 years.

Wintriss Shadow® light curtain systems are presence sensing devices that can be used as point of operation safeguarding devices on any part revolution clutch power press, hydraulic, or pneumatic machine that can be stopped anywhere in its stroke or cycle. The devices protect primary operators, helpers, and passersby while providing full visibility and accessibility to the point of operation.

Light curtains are typically installed in a vertical orientation (floor to ceiling) at the primary access to the point of operation. Often an additional set of optics is used to guard the rear side of the machine. Light curtains must be mounted at a “safe distance” determined by OSHA and ANSI standards that consider the stopping performance of the machine, hand speed constants, and other variable. When safety distances exceed expected operator waist dimensions an additional set of optics may be required to prevent a "walk through hazard".

Shadow® V and Shadow® VI Light Curtains

Shadow® V and Shadow® VI Light Curtains

Refer to our technical resources section:
Application Guideline for Proper Use of Light Curtains and
Light Curtain Application Issues – "Walk Thru Hazards".

Shadow® V self contained (no control box) systems are still available as are the Shadow® VI systems with control boxes. Shadow® I, II, and IV systems are obsolete and have been replaced by Shadow® V, VI, or Shadow® 8.

Light curtains are built to withstand the rigors of the pressroom, including severe shock, mechanical abuse, and lubricant spray. With more than 40,000 systems installed, the Shadow® has a proven track record.

 

Shadow® 8 Features

Wintriss Shadow® 8

Wintriss Shadow® 8

  • No control box is needed if connected to the new Wintriss press control WPC 1000 or WPC 2000
  • The heads are Type 4 control reliable – The main receiver has 2 safety PNP outputs
  • Connect up to 4 pairs of heads to a WPC or an optional control box with two cables
  • Rugged extruded heads – only 1.5" x 2", in lengths from 12" to 59" (extensions from 9")
  • Programmable fixed, and 1-beam floating blanking windows
  • Type 4 CE approval
  • Diagnostics display
  • Easy to align with individual beam indicators
  • 2 cross-checked PNP safety outputs
  • 2-year warranty, 48-hour service turnaround

Optional Shadow® 8 Control Box Features

  • Two cross-checked captive contact stop relay outputs
  • 24VDC power supply for the light curtain heads
  • Two key switches for programming fixed blanking windows
  • Dry-contact auxiliary output for non-safety applications like a beacon or alarm

Shadow® 8 heads connect directly to the new WPC 1000 and WPC 2000 without a 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

Wintriss Shadow® 8 Press

Wintriss Shadow® 8 Press

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 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 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.

Floating Blanking Window

Shadow® 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 Verifications

Instead of saying "designed to meet", Wintriss felt it was important to subject their 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/Tagout

Shadow® 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 Support

It’s necessary to have a thorough understanding of the various safety regulations when applying a safety light curtain system in your application. PRI Application Engineers and Wintriss technical support personnel 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.
