The setting is done by placing of magnetic pen
MP-8 to sensitive spot
the sensor. Short time
of the magnetic pen to the sensitive spot
the sensor open. Long attach (at least
of the pen when the level is changed, defines
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.
When changing the fluid it is necessary to make
the new 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
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:
-
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.
Put the level of the measured medium in the state above the upper edge of the
4.
sensor in the tank or in the gauge-pipe.
5.
Attach the magnetic pen MP-8 to the sensitive spot
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).
