If 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.
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).
