Banner EZ-SCREEN LS is a two-piece (emitter and receiver), redundant, microprocessor controlled, opposed-mode optoelectronic “light curtain” or “safety light screen”.
Models are available in 14 mm, 23 mm or 40 mm resolution. Up to four pairs of SLLC model emitters and receivers can be cascaded together. Emitters have a row of synchronised modulated infrared LEDs in a robust, compact metal housing. Receivers have a corresponding row of synchronised photodetectors.
The sensing field created by the emitter and receiver is called the “defined area”.Its width and height are determined by the length of the sensor pair and the distance between them. The sensing range spans from 100 mm to 12 m which decreases if corner mirrors or lens shields are used.
The length of the sensor pair (housing) is dependent on the model, with lengths available from 280 mm to 1820 mm. The end to end sensing design of the EZ-SCREEN LS allows mounting with minimal or no gaps in detection when using the centre-mount of side-mount brackets.
The EZ-SCREEN LS models have a trip output (auto power-up and automatic reset). In typical operation if any part of an operator’s bodyof more than a pre-determined cross sectionis detected, the solid-state output signal switching device (OSSD) safety outputs turn off.
These safety outputs are connected to the guarded machine’s final switching devices that control the machine primary control elements, which immediately stop the motion of the guarded machine. When the defined area becomes clear, the OSSD outputs can turn on.
EZ-SCREEN LS sensors are extensively tested to establish an extremely high degree of confidence when properly installed, so system component can cause a failure to danger. Because of the dual scan technology, the sensors are also highly immune to EMI, RFI, ambient light, weld flash and strobe light.
Additional features include selectable scan code via hook up, an auxiliary fault output, a recessed exit window, and robust metal housing and endcaps for industry leading durability. The cascading models also can connect and remotely locate an EZ-LIGHT using a cord set.
