7.4 Determining Interconnect Cordset Lengths
The following Cordset length charts are possible combinations
for each side of example cascaded systems. Model DELP-..E
cordsets (24 awg wire) used for calculations. Other lengths and
combinations are possible; please call factory for assistance.
As the machine interface Cordset lengthens, the voltage drop

Figure 7-2. Cordset length options for two cascaded light screens
Figure 7-3. Cordset length options for three cascaded light screens
increases, which results in shorter possible interconnect Cordsets
to maintain supply voltage requirements at the cascaded sensor.
See Section 2 for Cordsets.Due to the large number of possible
combinations, the table in Figure 7-4 includes only applications
in which L2 = L4. A common installation example is one that
protects two areas of a machine (e.g., the front and back of a
power press) and uses four EZ-SCREEN LP pairs to create two
“L”-shaped sensing fields.
