5. Adjust the switching point for channel 2 in the same way with
potentiometer " CH2 "
1. Make sure that switches 1 and 7 on the DIL switch block are set
to " min. " and switch 6 to " Single-point control ". The switches for
the switch-on and switch-off delay should be set to " 0 s ".
2. Set the potentiometer of the requested channel to the left end
position, the yellow LED display lights
3. Empty the vessel down to the requested min. level
4. Turn the potentiometer slowly clockwise until the yellow LED
display extinguishes
5. Adjust the switching point for channel 2 in the same way with
potentiometer " CH2 "
6.4 Switching point adjustment, single-point
control with capacitive sensor (limit level)
When using a capacitive point level sensors, the switching point is
mainly determined through the installation position. Via the potentiom-
eter, the switching point is adapted to the measured medium. Please
also observe the operating instructions of the sensor, especially the
sensitivity adjustment.
Note:
In order to set a reliable, precise switching point, the vessel must
be filled (sensor uncovered and covered). If this is not possible, you
can carry out the adjustment with an empty vessel up to step 4 and
"search" for the (approximate) switching point. Check or adjust the
switching point later on during operation when the sensor is covered.
Depending on the mode you now adjust the switching point as de-
scribed in the following.

sensor
1. Make sure that switches 1 and 7 on the DIL switch block are set
to " max. " and switch 6 to " Single-point control ". The switches
for the switch-on and switch-off delay should be set to " 0 s ".
2. The vessel should be empty i.e. the sensor must not be covered
