8. Conguration
The sensor can be congured either via qTeach,
remote teach, FlexProgrammer or IO-Link. If
formation of foam or adhesion of media have to be
detected, a conguration with the FlexProgrammer
will be necessary.
If for both switch outputs different switch points or
media have to be congured, a conguration with
FlexProgrammer or qTeach is also necessary.
Configuring with qTeach (Standard version)
Via qTeach, the switch points SW1 and SW2 can
be congured independently. Switch output SW1
is NO (normally opened) and switch output SW2 is
NC (normally closed).
Conguration is only possible during the rst
5 minutes after connecting the voltage supply.
After that, qTeach will be locked.
Note: For a graphical overview of the conguration
procedure refer to “14.5 Conguration procedure
with qTeach” on page 16.
9Sensor is connected.
fHold screwdriver or other metal object on the
qTeach detector.
The LED is blinking magenta at 1 Hz for
3 seconds. For selecting the switch the LED
alternates between yellow and blue in 2 second
intervals.
fWhen the LED has the color of the desired
switch, remove the screwdirver or metal object
from the qTeach detector to select the according
switch:
SW1: yellow
SW2: blue
The LED is blinking in the selected color at 0.5 Hz.
fPut the sensor tip into the media and touch the
qTeach area.
The LED ashes in the selected color while the
teaching process is running.
10 / 48
For selecting the switching window the LED
alternates between green, cyan and white in
2 second intervals.
f
Hold screwdriver or other metal object on the
qTeach detector.
f
When the LED has the color of the desired
switching window, remove the screwdriver or
metal object from the qTeach detector to select
the according switching window:
Switching window ±12%, hysteresis 4%: green
Switching window ±6%, hysteresis 2%: cyan
Switching window ±3%, hysteresis 1%: white
The conguration is complete and the changes are
saved.
If the DC value of the media is too close to air, the
most narrow switching window has to be selected.
If the LED ashes red (indicating an error) or
if the conguration time of 5 minutes has been
exceeded, no changes are saved.
f
To restart the conguration disconnect and
reconnect the voltage supply.
Conguration via qTeach is enabled in the factory
settings and can be disabled by the user.
