Installation of Multiple Systems
Whenever two or more EZ-SCREEN Type 2 emitter and receiver pairs are adjacent to one another, optical crosstalk may
take place between the systems. To minimize optical crosstalk, alternate the positions of the emitters and receivers (see
Figure 9
on page 19).
When three or more systems are installed in the same plane (as shown in
Figure 9
on page 19), optical crosstalk may
occur between sensor pairs whose emitter and receiver lenses are oriented in the same direction. In this situation,
eliminate optical crosstalk by mounting these sensor pairs exactly in line with each other within one plane, or by adding a
mechanical barrier between the pairs.
