These models can be used as stand-alone light screens, or can be cascaded up to four pairs in one system. The cascaded sensor pairs can be any length, any number of beams, or have different resolutions (14 mm, 23 mm, and 40 mm), as long as each emitter matches its receiver.

    11.2 Determining Interconnect Cordset Lengths The following cordset length charts are possible combinations for each side of example cascaded systems. Model DELS-11...E cordsets are used for calculations. Other lengths and combinations are possible; call Banner Engineering for assistance. Figure 44. Cascade Cordset Connection As the machine interface cordset lengthens, the voltage available at the first (master) sensor pair decreases, which results in shorter possible interconnect cordsets to maintain supply voltage requirements at last cascaded sensor.

    IM-T-..A interface modules provide forced-guided, mechanically-linked relay (safety) outputs for the EZ-SCREEN LS System with an 8-pin interconnect (with EDM function). The IM-T-..A interface module is required to be monitored by the EDM function and should not be used with EZ-SCREEN LS with a 5-pin interconnection (P5). See Banner datasheet p/n 62822 for more information.
