8 .  Setting

a) Mode O 

(normally open)

1.  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.

2.  Attach the magnetic pen MP-8 to the sensitive spot 

M

for maximum 2 seconds. When the 

LED goes out, the sensor is in the state open.

3.  After removal of the magnetic pen check the status of orange lights:

  -  

f the LED doesn´t light or is flashing rapidly (0.2 s), go to step 4.

  -  

If the LED lights, you must repeat step 2 so as not to exceed the limit of 2 seconds attaching 

magnetic pen.

4.  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.

5.  Attach the magnetic pen MP-8 to the sensitive spot 

M

for minimum 4 seconds.       When the 

LED lights up, the sensor is in the state closed.

6.  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.

-   If the LED is flashing, the sensor didn´t recognize upper and lower limits. In this case, first 

verify that at the step 1 the level of the measured medium was below the lower edge of the 

sensor and at the step 3 the level of the measured medium was above the upper edge of 

the sensor. Then make sure that the thickness of the gauge-pipe wall or the tank wall does 

not exceed the limit specified in the Technical specifications (p. 2). If not, check there isn´t 

a thick layer of sediment on the inner wall of the tank or the gauge-pipe.

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).

Sensitive 

spot

The setting is done by placing of magnetic pen MP-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 sensitivity for 

the measured medium and switching modes “O“ (normally 

open) or “C“ (normally closed) is set. When changing the 

fluid it is necessary to make the new setting.
