PrOduCT dESCriPTiON
Through wall level switches GPLS-25 are intended for liquid (conductive and non-
conductive) level detection on glass or plastic gauge-pipes, tubes 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.

2. ElECTriCal CONNECTiON
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.
Connection scheme of sensor with “S“ type output
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.

Sensitive spot
3. SENSOr SETTiNgS
The setting is done by placing of magnetic pen
MP-8 to sensitive spot Mlocated on the front of
the sensor. Short time attaching (up to 2 sec.)
of the magnetic pen to the sensitive spot Mmakes
the sensor open. Long attach (at least 4 sec.)
of the pen when the level is changed, denes
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.
Whenchangingtheuiditisnecessarytomake
the new setting.
a) Mode O (normally open)
Put the level of the measured medium in the state below the lower edge of the
sensor in the tank or in the gauge-pipe.
Attach the magnetic pen MP-8 to the sensitive spot Mfor maximum 2 seconds.
When the LED goes out, the sensor is in the state open.
After removal of the magnetic pen check the status of orange lights:
Put the level of the measured medium in the state above the upper edge of the
sensor in the tank or in the gauge-pipe.
Attach the magnetic pen MP-8 to the sensitive spot Mfor minimum 4 seconds.
When the LED lights up, the sensor is in the state closed.
After removal of the magnetic pen check the status of orange lights:

If the LED lights, settings of the sensor is correct.
If the LED doesn´t light, the sensor was set incorrectly and you must repeat
the procedure from step 1.

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.

If the LED doesn´t light, you must repeat step 2 so as to observe the limit
of 4 seconds attaching magnetic pen.
If the LED doesn´t light, settings of the sensor is correct.
If the LED lights, the sensor was set incorrectly and you must repeat the
procedure from step 1.
