Safety light curtain with integrated muting
The EZ-Screen from Banner Engineering is a Type 4 safety light curtain designed for use on smaller production machines in compact spaces.
Banner Engineering's EZ-Screen Low-Profile Safety Light Curtain with Integral Muting is a Type 4 safety light curtain designed for use on smaller production machines. They are designed to provide optimal performance in compact spaces, yet be robust enough for large power presses.
Safety light curtains protect personnel from injury and machines from damage by guarding points of operation, access, areas and perimeters. The two-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. Furthermore, they 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 in. to 23 ft). 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 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.
Capable of two or four mute device/sensor hookup options, including a cost-effective 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. The optional CSM Muting Splitter Cordset provides a complete QD connectorized solution.
Featuring a built-in muting function, the new EZ-Screen safety light curtains do not require a third box, which helps facilitate easy setup, minimizes wiring requirements and reduces installation costs. Setup can be performed without a PC, hand-held programmer or other device; and DIP switch configuration features many of the same functions as a standard EZ-Screen LP.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
