11.1.1 System Components and Specifications
A multiple-light screen cascaded EZ-SCREEN LS system includes compatible emitter/receiver pairs (up to four), a
terminator plug (shipped installed on each cascade receiver) for the last receiver in the cascade, two RD cables or pigtail
cables to interface with the machine and provide power to the system, and pairs of double-ended (sensor interface) cables
to interconnect the emitters and the receivers in the cascade. (A “dummy” plug is installed at the cascade end of each
emitter. It is not required for operation, but maintains the emitter’s IP67 rating.) Additional cordsets may be used to enable
quick disconnect (QD) connections; see
on page 80.
The terminator plug (model EZLSA-RTP-1) must be used on the receiver in a stand-alone system, and on the last receiver in
a multiple-pair cascade, unless an EZA-RBK-1 key switch for remote teach fixed blanking, an RDLS-8..D cordset interfaced
with an E-stop or other hard contacts is in place (see
Emergency Stop Buttons in Cascaded Systems
Interlock Switches in Cascaded Systems
on page 76), or an EZLSA-K30LGR EZ-LIGHT or DELSEF-xxE cordset with a
remotely located EZ-LIGHT or indicator.
Note: The machine interface cable must connect to the sensor end adjacent to the status indicators.
Available single-ended, double-ended, and splitter cordsets are listed in
on page 80. Cordset lengths are limited
– for both the machine interface/power cables and the sensor interconnect cables; see
Determining Interconnect Cordset
on page 71 for more information.
11.1.2 Receiver Display
In Run mode, the 7-segment display shows the following. See
on page 65 if any indication is flashing.

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.
Note: The machine interface cable (e.g. RDLS-8xxD, DELSE-8xxD) must connect to the sensor end
adjacent to the indicators and serial number label for the system to operate properly.
