Through wall level switches NC30 Series level switches are intended for liquid
(conductive and non-conductive) level detection on glass or plastic pipes, tubing
and tanks. The sensor is equipped with high frequency technology which allows
reliable operation even for sensing of the adherent electrically conductive medium.
The sensitivity and modes (O - normally open or C - normally closed) of the switches
can be easily set by placing magnetic pen on sensitive spot. Output performance -
transistor output with open collector (PNP) or two wire electronic switch (S). This
connection is done by means of two wires directly into a circuit with relay or to binary
input of control system.

Positive pole (+U) of power supply is connected through a load (relay) to brown wire
or pin connector No. 1, negative pole is connected to while wire or pin connector No.3.
Note:
The sensor output is protected againts short circuits. Capacity loads and loads with low sleep resistance (bulb) the
sensor evaluation as a short circuit. In case of high ambient electromagnetic interference, parallel conductors with
power lines, or lines at distances greater than 30 m, we recommend to use shielded cable.

Positive pole (+U) of power supply is connected to brown wire or pin connector No.1,
negative pole is connected to blue wire or pin connector No.3. Load (relay) is connec-
ted to black wire or pin connector No.2.

Electrical connection must be done in de-energized state!
For switching supply sources, it is necessary to check that the input is galvanically
separated from the network side and that they are tted with a lter suppressing the
conforming interference (terminals + and – oscillate together towards the ground
potential), or the interference is removed in another manner.

3. SENSOr SETTiNgS
The setting is done by placing of magnetic pen
PM-8 to sensitive spot M located on the front of
the sensor. Short time attaching (up to 2 sec.)
of the magnetic pen to the sensitive spot M makes
the sensor open. Long attach (at least 4 sec.)
of the pen when the level is changed, defines
closed state of the sensor. In this way the sensiti-
vity for the measured medium and switching modes
“O“ (normally open) or “C“ (normally closed) is set.

For security reasons, we recommend to set the mode O (normally open, sensor closes
when immersed) for minimum level detection. Any failure of the sensor or wiring is equally
apparent as the emergency level state. Analogously – for the maximum level detection
is recommended to set the mode C (normally closed, sensor opens when immersed).
* Sensor with “S“ type output, for each ash of the LED switches its output on for approx. 3 ms. This period is
sufciently short to avoid unwanted switching of relay contacts. For binary inputs, we recommend to set the lter so
as not to respond to pulses shorter than 3 ms.
