10.2
Output as alarm output
NOTE
This function can be configured only via IO-Link!
Additionally to the signal level warning (VMA) you can also configure the
Q1 or Q2 output for the switching signal "No measurement possible". The
output behavior can be inverted.
This function is especially useful if "Alarm function = Hold" has been set for
the sensor behavior. This allows you to determine whether the sensor actu-
ally is able to measure or a held value is output, even if an output signal is
provided at any time.
Set the alarm function via the index 104.

10.3
Centering function
Use the centering teach to move the center of the switching window or
the center of the analog output scaling (12 mA/5 V) to the newly taught-in
position. A centering teach is possible for Q1 windows, Q2 windows, and an
analog output.
You can perform the centering function in the following ways:
• Teach via multifunctional input MF (

Page 37, Chapter 8.7)
• Teach via IO-Link
• Value input via IO-Link.
→
For setting via IO-Link, see Page 41, Chapter 9.3.2, indexes 94, 95,
and 96.
The previously taught-in relative distance between near and far is retained.
The values for near and far must not be moved beyond the measuring
range of the sensor via a centering function. If the teach was not success-
ful, the Q1 and Q2 LEDs flash alternately.
