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.

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).
