EZ-SCREEN LS Safety Light Curtain in an IP69K Hygienic Housing for use in washdown environments

• Hygienic design suited for food and beverage applicaons

• FDA-grade polycarbonate tubing and stainless steel end caps

• Stainless steel mounng components

• Brackets and fasteners sold separately

• Ideal for high-pressure washdown applicaons

• IP69K

• EZ-SCREEN LS emiers and receivers are factory-installed in the enclosures

The EZLSA-HTE EZ-SCREEN LS Safety Light Curtain in an IP69K hygienic housing is designed specically for use in hygienic and

washdown applicaons. The enclosures are constructed of FDA-approved rugged polycarbonate tubing with stainless steel end

caps. The enclosures are mounted with stainless steel mounng brackets and fasteners.

Using the enclosure aects the sensing range. When used in pairs, the range is reduced by 30%.

Important Informaon

The EZ-SCREEN LS instrucon manual with installaon instrucons, applicaon requirements and guidelines, EC Declaraon of Conformity, and technical

specicaons can be found on the accompanying CD-ROM or downloaded at www.bannerengineering.com by searching document p/n 179480.

The accompanying CD-ROM contains important warnings and safety instrucons that must be observed prior to the installaon and operaon of the

device.

If the CD-ROM cannot be used, download the full Instrucon Manual and Checkout Cards (listed in the manual), including warnings and safety

instrucons, from www.bannerengineering.com. To order a printed copy or if there are any quesons regarding the applicaon or use of the device,

contact Banner Engineering at (763) 544-3164 or at 1-888-3-SENSOR in the United States.

CAUTION: Reduced Sensing Range—Sensing range is reduced 30% because of tubular construcon.

WARNING:

•Maintain Required Safety Distance

•Failure to calculate this distance correctly and to maintain minimum safety distance could result in serious injury or

death.

• The light screen produced by the opcal safety system sensors must be placed at a minimum safe distance from the

dangerous moon of the machine being guarded. This necessary minimum distance is called the safety distance, and is

discussed in the instrucon manual.

Adjacent Reecve Surfaces

WARNING: Avoid Installaon Near Reecve Surfaces

Avoid locang the sensing eld near a reecve surface; it could reect sensing beam(s) around an object or person within the

sensing eld, and prevent its detecon by the EZ-SCREEN LS. Perform the trip test, as described in the manual, to detect such

reecon(s) and the resultant opcal short circuit. Failure to prevent reecon problems will result in incomplete guarding and

could result in serious injury or death.

A reecve surface located adjacent to the dened area may deect one or more beams around an object in the dened area. In the worst case, an

opcal short circuit may occur, allowing an object to pass undetected through the dened area.

This reecve surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the oor, or the walls. Beams

deected by reecve surfaces are discovered by performing the trip test and the periodic checkout procedures. To eliminate problem reecons:

• If possible, relocate the sensors to move the beams away from the reecve surface(s), being careful to maintain adequate separaon distance

• Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reecvity

• Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resoluon resulng from the opcal short

circuit and use the corresponding depth penetraon factor (Dpf or C) in the Safety Distance (Minimum Distance) formula; or mount the sensors

in such a way that the receiver's eld of view and/or the emier's spread of light are restricted from the reecve surface

• Repeat the trip test to verify that these changes have eliminated the problem reecon(s). If the workpiece is especially reecve and comes

close to the dened area, perform the trip test with the workpiece in place
