Banner Engineering’s EZ-Screen Low-Profile Safety Light Curtain with integral muting is the newest Type 4 safety light curtain of the company’s popular machine safety product line. Designed for use on smaller production machines, low-profile safety light curtains provide optimal performance in compact spaces, yet are robust enough for large power presses, the company says. The introduction of the new integral muting models allows Banner’s EZ-Screen family to provide increased mounting flexibility, hookup options and additional functionality at a lower cost. The EZ-Screen LP with integral muting has a sensing range that spans from 100 mm to seven metres. Offering seven different, predefined muting configuration options – including bypass, mute-dependent override, mute enable and mute-cycle time extensions for “L”-style cell exit application – the safety light curtain provides versatile performance for diverse application requirements. Additionally, 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 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. Capable of two or four mute device/sensor hookup options, including a two sensor “X-pattern” solution used for material entry and exit applications, and “L” sensor solution that minimizes the floor space in manufacturing cell exit applications, the EZ-Screen LP with integral muting provides enhanced application flexibility.
