Low-profile safety light curtains
EZ-SCREEN® Low-Profile Safety Light Curtain with Integral Muting from Banner Engineering is designed for use on smaller production machines, yet are robust enough for large power presses.
With the new integral muting models the EZ-SCREEN family can provide increased mounting flexibility, hookup options and additional functionality–all at a lower cost. The variety of sizes, end-to-end sensing and compact design allows installation within the machine frame to eliminate any holes or dead zones in the sensing field. Also less power is consumed and fewer components are needed than with traditional safety light curtains. The curtains protect personnel from injury and machines from damage by guarding points of operation, access, areas and perimeters. The 2-piece optoelectronic safeguarding device creates a screen of synchronized, modulated infrared sensing beams that extend from end-to-end of the housing—ensuring operators are completely protected from machine safety hazards. The curtains are highly-immune to EMI, RFI, ambient light, weld flash and strobe lights, and come equipped with factory burned-in emitter and receiver circuitry for toughness, dependability and vibration tolerance.The EZ-SCREEN LP with integral muting has a sensing range that spans from 100 mm to 7 m (4- to 23-ft.). Offers 7 different, predefined muting configuration options—including Bypass, Mute-Dependent Override, Mute Enable and Mute-cycle time extensions for “L”-style cell exit application. Mute Lamp and Status Outputs can be relayed to the EZ-LIGHT (or other indicating devices) with a removable disconnect (RD) cordset and accessory end-cap mounting bracket, while easy-to-see Status, Reset, Zone, Mute Device and Diagnostic indicators and displays communicate the number of beams blocked and provide detailed diagnostics. A selectable emitter test option is able to simulate a “blocked” condition as well.
