* Sensor with “S“ type output, for each flash of the LED switches its output on for approx. 3 ms. This period is
sufficiently short to avoid unwanted switching of relay contacts. For binary inputs, we recommend to set the filter so
as not to respond to pulses shorter than 3 ms.

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
M
for
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:
If the LED lights or is flashing rapidly (0.2 s), go to step 4.
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.
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.
