3.2 General operation
The sensor measures the distance to a measurement object by calculating the angle
(triangulation principle). For this purpose, the sensor projects a laser spot onto the target. The
surface of the measuring object reflects the impinging radiation into the receiver of the sensor. By
evaluating this radiation, the distance between the sensor and the target can be determined. The
measured distance is provided as a measured value via the following channels integrated in the
sensor:
digital IO-Link interface
analog output
The following options are available for parameterizing the sensor:
IO-Link parameters
Teach button on the sensor

OUTPUT YellowNo valid signal within the
Measuring range
Critical signal quality
In the factory settings, the OUTPUT (pin 4) and thus also the yellow LED follow the function of
the alarm output. Alternatively, you can select the function of the switching output for the OUT-
PUT and the yellow LED.
3.4.2 Teach button
As an alternative to setting the sensor parameters via IO-Link, you can set the sensor via the
Te- ach button. Adjustable parameters:
Analog measuring field
Zero point
Reset sensor to factory settings
INFO
Via IO-Link, you also have the option of setting the mode of the teach button. You can choose
between the Xpert (factory settings) and Xpress modes. For more information, see Function of
the teach button [► 36].
The teach button is automatically deactivated after 5min (timeout can be parameterized via
IO-Link). If the teach button is held down for longer than 12s, the sensor switches to
operational mode without performing a parameterization.
The parameterization via the teach button is carried out according to the procedure described
below.

Teach analog measuring field
Procedure:
a) Briefly press the Teach button.
Green and yellow LEDs light up (teach button is active). If the LEDs do not light up,
restart the sensor.
b) Press and hold the teach button for 4s.
Yellow LED flashes with 2Hz.
c) Place the target at position 1 (P1) and briefly press the teach button in- ner 60s.
The min. limit of the analog measuring range is taught-in (distance at which 4mA
are displayed).
d) Place the target on P2 and briefly press the Teach button within 60s.
The max. limit of the analog measuring range is taught-in (distance, at which 20mA
are displayed).
Result:
Teach-in ok: Green and yellow LED light up briefly. The sensor then returns to
operational mode.
Teach-in not ok: Green and yellow LEDs flash simultaneously at 8Hz.
NOTE
The characteristic curve of the analog output can be inverted by the teaching process (negative
slope). To do this, teach the maximum distance for P1 and the minimum distance for P2.

the sensor.
Screws: 2 × M3
Tightening torque: 0. 6 Nm ±10 %
Mounting the sensor near a wall or a machine component:


Mounting on targets with colored edges/with different surface reflectivity: Align the sensor parallel
to the colored edge to avoid measured value errors.
Mounting near strong ambient light:
Avoid ambient light entering the detection range of the receiver.

Mounting of several sensors close to each other:
Avoid overlapping the detection ranges of the receivers. Only your own laser spot may be
within the detection range of the receiver.
