K1/K2 EXTERNAL CONTACTORS CONNECTION

In every operating mode the K1/K2 external contactors feedback can be activated.
If you want to use this control feature, connect the PIN 4 of 8 poles M12 connector with the
power supply (+24VDC) through the series of N.C. contacts (feedback) of external
contactors.

MULTIPLE SYSTEMS

When more than one SLC / SLG 210 RF system is used, precautions must be taken to avoid
optical interference between them: install units so that the beam emitted by the Emitter of
one system can only be received by the relative Receiver.
Figure 17 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.
