b) Mode C (normally closed)

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

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

3. 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.

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

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

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

- 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.

After this settings the sensor responds to the level immersion and emersion in the upper half of

the sensing area and the hysteresis size 5 mm (1/8 of the distance between the bottom and the

top of the sensor).

Slow flashing (period 0,8 sec.) – Short circuit at sensor output

* Sensor with "S" type output, for each flash of the LED switches its output on for approx. 3 ms. This period is suffici-

ently 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.
