Settings are performed by placing the magnetic pen on the sensitive
spot marked
“+”
or
“–”
located beside the connector or cable gland.
This method is used to set the sensitivity to the measured medium,
switching (O, C), with or without the presence of medium. The third func-
tion is designed for fine-tuning the sensor sensitivity. Upon a change
in the measured medium, it is necessary to perform new limit settings.
Information on settings of the sensor are stated in the instructions for use.

A sensor with NPN or PNP output can be loaded only by resistive
or inductive load. The positive pole of the supply voltage (+U) is
connected to the brown wire

capacitative loads and low resistance loads (bulb) are evaluated
by the sensor as a short circuit.
Wiring diagrams are provided in the figures on the right.
Note: In case of strong ambient electromagnetic interference,
paralleling of conductors with power distribution, or for the distri-
bution to distance over 30 m, we recommend using shielded cable.
Sensors RFLS-35 with type of cable outlet A, B, V or H are
connected to assessing units permanently connected by PVC
cable. Design diagrams are provided on page 3.

Sensors RFLS-35 with connection method type C (see page
3) are connected to assessing units by means of a connector
socket with compression cable (length 2 or 5 m), or by means of
a connector socket without cable (see accessories). In this case
the cable is connected to the inside pins of the socket according
to the figure on the right. The recommended diameter of this
cable is 4 to 6 mm (the recommended cross-sectional area is
0.5 to 0.75 mm
