EZLSA-TE-1820

## **EZLSA-TE Series Tubular Enclosure** 

## **Datasheet** 

_Tubular enclosures for EZ-SCREEN LS models mounted in washdown environments._ 

- FDA-grade polycarbonate tubing and acetal end caps 

- Stainless steel mounting components 

- Brackets and fasteners included 

- Ideal for high-pressure washdown applications 

- IEC IP67, IP69K 

- Twenty-three models are available to accommodate EZ-SCREEN[®] LS models 

The EZLSA-TE Series Tubular Enclosure is designed specifically for use with Banner EZ-SCREEN LS emitters and receivers. The enclosures are constructed of FDA-approved rugged polycarbonate tubing with FDA-approved acetal end caps. The enclosures are mounted with stainless steel mounting brackets and fasteners. 

Using the enclosure affects the sensing range of the sensor used. When used in pairs, the range can be reduced by 30%. 

**When using the enclosure, you must use an RDLS cordset, which is sold separately.** Refer to the EZ-SCREEN LS Instruction Manual (p/n _179480_ ) for a complete list of available cordsets.

**CAUTION: Reduced Sensing Range** —Sensing range is reduced 30% because of tubular construction. 

**WARNING: Maintain Required Separation Distance** — The light screen produced by the optical safety system sensors must be placed at a minimum safe distance from the dangerous motion of the machine being guarded. This necessary minimum distance is called the separation distance, and is discussed in the instruction manual. Failure to calculate this distance correctly and to maintain minimum separation distance can result in serious injury.

|1|Install the long halves of the EZLSA-MBK-11 brackets onto both<br>ends of the light curtain using the supplied hardware and t-nuts.<br>The short halves of the EZLSA-MBK-11 brackets are not used in<br>this application. The brackets should slide onto the light curtain<br>until they mate with the end cap.<br>Tighten the screws, but do not exceed a maximum torque of 36<br>in-lbs.||

## **Adjacent Reflective Surfaces** 

## **WARNING: Avoid Installation Near Reflective Surfaces** 

Avoid locating the defined area near a reflective surface; it could reflect sensing beam(s) around an object or person within the defined area, and prevent its detection by the EZ-SCREEN LS. Perform the trip test, as described in the manual, to detect such reflection(s) and the resultant optical short circuit. **Failure to prevent reflection problems will result in incomplete guarding and could result in serious injury or death.** 

A reflective surface located adjacent to the defined area may deflect one or more beams around an object in the defined area. In the worst case, an optical short circuit may occur, allowing an object to pass undetected through the defined area. 

This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the floor, or the walls. Beams deflected by reflective surfaces are discovered by performing the trip test and the periodic checkout procedures. To eliminate problem reflections: 

- If possible, relocate the sensors to move the beams away from the reflective surface(s), being careful to maintain adequate separation distance 

- Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reflectivity 

- Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resolution resulting from the optical short circuit and use the corresponding depth penetration factor (Dpf or C) in the Safety Distance (Minimum Distance) formula; or mount the sensors in such a way that the receiver's field of view and/or the emitter's spread of light are restricted from the reflective surface 

- Repeat the trip test to verify that these changes have eliminated the problem reflection(s). If the workpiece is especially reflective and comes close to the defined area, perform the trip test with the workpiece in place 

## **Do not position reflective surfaces within the shaded area**
