5.1.8 Installation of Multiple Systems
Whenever two or more EZ-SCREEN LS Basic 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
on page 28).
When three or more systems are installed in the same plane (as shown in
on page 28), 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.
To further aid in avoiding crosstalk, the sensors feature two selectable scan codes. A receiver set to one scan code will not
respond to an emitter set to another code.
