• Cascading (available on SLPC.. models) (see "Cascade" on page 69)
These functions are configured via DIP switches (behind the access door on the front of each sensor) and/or the sensor
wiring configuration. The sensing resolution is determined by the emitter and receiver model.
NOTE: This manual refers to an emitter, its receiver, and their cabling as "a System".
Banner EZ-SCREEN SLS emitters and receivers provide a redundant, microprocessor-controlled, opposed-mode optoelec-
tronic "curtain of light", or "safety light screen". EZ-SCREEN SLS typically is used for point-of-operation safeguarding, and is
suited to safeguard a variety of machinery.
The EZ-SCREEN SLS is a two-piece (two-box) system comprising an emitter and a receiver, but no external controller. The
external device monitoring (EDM) function ensures the fault detection capability required by EN ISO 13849-1 Categories 3
and 4 without a third box, a controller or a "smart" (self-checking) safety module required of systems without EDM.
The EZ-SCREEN SLS emitters have a row of synchronized modulated infrared (invisible) light-emitting diodes (LEDs) in a
compact metal housing. Receivers have a corresponding row of synchronized photodetectors. The light screen 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 maximum range is dependent on the resolution; range decreases if corner mirrors are used.
Emitter and receiver pairs with 14 mm (0.55 in) resolution have a maximum range of 6 m (20 ft), and pairs with 30 mm (1.18
in) resolution have a maximum range of 18 m (60 ft).
In typical operation, if any part of an operator’s body (or any opaque object) of more than a pre-determined cross section is
detected, the solid-state Output Signal Switching Device (OSSD) safety outputs turn OFF. These safety outputs are connect-
ed to the guarded machine’s Final Switching Devices (FSDs) that control the machine primary control elements (MPCEs),
which immediately stop the motion of the guarded machine.
An auxiliary (aux.) output may be used to signal the state of the OSSDs to a process controller (see "External Device Moni-
toring " on page 44.
Electrical connections are made through M12 quick-disconnects. Some emitter models have a 5-pin connector for power and
the Test function. Other emitters and all receivers have an 8-pin connector for power, ground, inputs, and outputs.
Functions such as Trip/Latch select, Display Invert, Cascading, Fixed Blanking, Reduced Resolution (Floating Blanking),
Scan Code Select, and External Device Monitoring are described in "Features" on page 9. An auxiliary (aux.) output may be
used to signal the state of the OSSDs to a process controller. All models require a supply voltage of +24 V DC ±15%.
Both emitter and the receiver feature 7-segment diagnostic displays and individual LEDs to provide continuous indication of
operating status, configuration, and error conditions.
