MULTIPLE SYSTEMS
When more than one SLC 410 B / BM system is used, precautions must be taken to avoid
optical interference between them: install the units so that the beam emitted by the Emitter of
one system can only be received by the relative Receiver.
Figure 23 illustrates some examples of correct positioning when two photoelectric systems
are installed. Incorrect positioning could generate interference, and may result in
malfunctioning.
Systems installed alongside each other: A
Installation of two adjacent Emitters
Overlapping systems: B
L-shaped installation: C
Crossed positioning of Emitters and receivers
This operation is not necessary in case of coexistence of a MASTER and a SLAVE.
