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 RFLC 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 9 illustrates some examples of correct positioning when two photoelectric systems are
installed. Incorrect positioning could generate interference, and may result in malfunctioning.
