Transmission Channel - Leuze electronic SOLID-2SF-M Connecting And Operating Instructions

3.2

Transmission channel

The infrared beams are modulated with specially coded pulse packages so that they are
distinct from ambient light, thus ensuring undisturbed operation. Welding sparks or warning
flash lights from passing forklifts do not having any effect on the protective field.
If two protective fields are located directly next to each other for two adjacent machines,
however, measures must be taken to ensure the optical protective devices do not affect
each other.
Another possible way to suppress mutual influence is to switch one of the two protective
devices from transmission channel 1 to 2 and therefore to differently formed pulse packages.
This solution should be considered when more than two optical protective devices must be
arranged next to each other.
a AOPD "A" transmission channel 1
b AOPD "B" transmission channel 2, not affected by AOPD "A"

The change from transmission channel 1 to 2 must be made both on the Transmitter and
the Receiver of the optical protective device in question. You will find more detailed
information in Chapter 6.
