2 Sensitivity Matching for Models LEVELTEC
Using Teach-in Key
The factory setting of the capacitive Leveltec level probe is a DC value of about ɛ 25 to
reliably detect uids with a water content of 20% or more.
For the following media / applications we recommend, however, to adjust the sensitivity
level:
• media with a very low DC value (e.g., fruit juice concentrates, sugar solutions,
edible oils, or other uids with little or no water content);
• viscous or adhesive media; or
• if the factory setting fails to achieve reliable switching behaviour.
.
Press the teach-in buttons to optimally adjust the sensitivity of the Leveltec level
probe to your application!

3 Sensitivity Adjustment Using Teach-in Key
Please follow these instruction for successful teach-in:
3.1 Teach-in with installed level probe
1. Make sure that the coupling part (PEEK) of the installed level probe is fully covered
by the medium to be detected.
2. The level probe’s supply voltage is connected.
3. Press the teach-in button "High" and keep it pressed for about 3 seconds.
4. Teach-in is completed and the LED probe should now light up red (i.e., the sensor
is covered).
5. The sensitivity setting is retained even after the supply voltage is switched o󰀨 and
can be repeated at any time as described above.
3.2 Teach-in with uninstalled level probe
1. Get a container lled with the medium to be detected (100ml or more).
2. Turn a hygienic weld-in lug (e.g., TEM1FTP16) towards the level probe.
3. Connect the level probe to the supply voltage (12–35VDC).
4. Dip the tip of the level probe into the medium until the front of the weld-in lug is
completely covered by the medium.
5. Press the teach-in button "High" (when submerged) and keep it pressed for about
3 seconds.
6. Teach-in is completed and the LED probe should light up in red when submerged
and in green when not submerged.
7. The sensitivity setting is retained even after the supply voltage is switched o󰀨 and
can be
repeated at any time as described above.
3.3 Teach-in the switch-o status
The switch-o󰀨 status can be set with the additional Teach-in "Low" button.
1. Make sure that the probe tip comes into full contact with the medium. If the LED
does not light up red, then rst follow the instructions of chapter 3.1. resp. 3.2.
2. Afterwards, make sure that the probe tip is not covered by the medium to be de
tected. Now there should only be a few buildups on the probe tip.
3. If the LED is green, no further setting is required.
4. If the LED lights up red, press the Teach-in button "Low" and hold it down for ap
prox. 3 seconds
5. The Teach-in "Low" has been carried out. The LED should light up green.
6. The sensitivity setting is retained even after the supply voltage is switched o󰀨 and
can be repeated at any time according to this scheme.
The device must not be used in hazardous areas.
