5 ‒ Installation and Electrical Connection | P3PC341 ‒ Laser Distance Sensor Triangulation 14
5.2 Adjustment
When adjusting sensors, note the following instructions so that the most stable object detection/measure-
ment can be achieved:
Steps/Edges/Depressions
If measuring directly next to steps/edges/depressions, make sure that the receiving beam is not covered
by the step/edge. The same applies when measuring the depth of gaps and holes.
With holes, blind holes and edges in the surface of moving parts, the sensor must be positioned so that
the edge does not obscure the laser dot.
Page 15
5 ‒ Installation and Electrical Connection | P3PC341 ‒ Laser Distance Sensor Triangulation 15
Round, Glossy surfaces
With round, glossy surfaces, the sensor should be positioned on an axis with the round object in order to
avoid reflection.
Measuring Objects with Evenly Positioned, Colored Edges
When oriented correctly, the influence on measuring accuracy is minimal. When oriented incorrectly, the
different reflectivity of the various colors will result in deviations.
Page 16
5 ‒ Installation and Electrical Connection | P3PC341 ‒ Laser Distance Sensor Triangulation 16
Moving Measuring Objects
When measuring a moving object, the object must be able to move transversely to the sensor. This pre-
vents shadows and direct reflection to the receiver.
5.3 Electrical Connection
• Wire the sensor in accordance with the connection diagram.
• Switch on the supply voltage (see section Technical Data [}9])
• If using IO-Link, connect the sensor to 18…30 V DC.
• If not using IO-Link, connect the sensor to 10…30 V DC.
• The blue supply voltage indicator lights up.
• Adjust the sensor so that the light spot strikes the object to be detected/measured.
DANGER
Risk of personal injury or property damage due to electric current.

Page 20
6 ‒ Settings | P3PC341 ‒ Laser Distance Sensor Triangulation 20
The teach-In function can be used to scale the analog output and assign the min./max. values to mea-
sured distances. By default, 4 mA/0 V corresponds to the minimum measuring range, and 20 mA/10 V
corresponds to the maximum measuring range.
300,0
Teach-In for 4 mA/0 V
1. Adjust the sensor so that the light spot strikes the object to be measured.
2. Press and hold the Teach-in key or the Enter key for 2 seconds until O starts to
flash slowly.
3. Release the Teach-in key or the Enter key.
4. The distance is taught in, and LED O flashes briefly twice in order to confirm suc-
cessful teach-in.
1000,0
Teach-In for 20 mA/10 V
1. Adjust the sensor so that the light spot strikes the object to be measured.
2. Press and hold the Teach-in key or the Enter key for 5 seconds until LED O starts to
flash rapidly.
3. Release the Teach-in key or the Enter key.
4. The distance is taught in, and LED O flashes briefly twice in order to confirm suc-
cessful teach-in.
INFORMATION
Depending on whether the smaller distance value is assigned to 4 mA/0 V or 20 mA/10 V, either a rising
or a falling analog characteristic curve results. If teach-in is conducted without an object or if an object is
too far from the sensor, the analog value is set to the maximum value of 20 mA/10 V, and the Power LED
lights up yellow. If an object that is too close is taught in, the analog value is set to the minimum value of
4 mA/0 V, and the Power LED also lights up yellow. If there is an error during teach-in preventing it from
being carried out, this is indicated by a red LED.

The functions described in the following section can be adjusted via wTeach or IODD per IO-Link, as well
as via the weCon app per Bluetooth, and the basic functions via the Display menu.
8.1 Sensor Functions
Function Possible settings Default
Exposure mode With black or glossy objects, it may be useful to increase the
exposure time. Decreasing the exposure time can be useful if
the sensor is aimed at very bright objects. The longer the ex-
posure time, the lower the speed of the sensor.
Auto
With the Adaptive Autoexposure function, the sensor automati-
cally sets its exposure time or light pulse duration to the object
to be detected up to a maximum value.
Fix
The exposure time is set via the fixed exposure time parame-
ter, i.e., not automatically adjusted by the sensor

Distance range A distance range in which signals are to be evaluated can be
defined within the working range. Signals outside the set dis-
tance range are ignored and are not included in the signal
evaluation. This means that ranges for which no usable sig-
nals are expected can be completely hidden.
This function can be used to suppress interfering signals, such
as those produced by a glass disk, for instance.

• Objects outside the set distance range are evaluated as
“No signal”.
• If a distance range is set, a blind spot directly behind this
range results. The sensor cannot detect any objects within
the blind spot. The size of the blind spot depends on the
reflectance of the interfering objects in the hidden area.
Sensitivity The sensor has a very high sensitivity and can detect objects,
measuring the distance to them, even when the signal is very
weak. In applications where the object to be detected yields
even weaker signals, e.g., due to large inclinations, it can be
helpful to further increase the sensitivity or to amplify the opti-
cal signal.
The higher the sensitivity, the more susceptible the sensor is
to interference. The speed of the sensor is not reduced by the
setting.

teach-in or change of the switching point, the hysteresis is re-
calculated and automatically updated in the hysteresis param-

ing to data sheet < 0.5% hysteresis < 0.5 mm

8.7 Differential and Thickness Measurement
In this operating mode, two sensors work together to calculate a difference or thickness based on the in-
dividual measurement results.
This eliminates the need for complex programming in the controller, and the system already provides a
calculated value. This value can then be used for a switching function or output via an analog output. Ad-
ditionally, the calculated difference or thickness is output as an absolute value via IO-Link.

It is recommended to arrange the sensors so that no area between the sensors remains uncovered by
their measuring range (Figs. 1 and 2). If this is the case, the object to be measured must be wider than
the uncovered area (Fig. 3).
The sensors must be aligned so that the transmitted beams strike the front window of the opposite sen-
sor. Care must be taken to ensure that they do not strike the emitter or receiver directly.

The ZC4G004 adapter can be used for easy wiring. In this case, the sensors must simply be connected
as shown. The sensors are automatically parameterized for the appropriate operating modes as soon as
they are connected. In this case, the main sensor is set to "thickness measurement" mode. If a differential
measurement is to be performed, the mode of operation must be adjusted accordingly.

The adapter’s connections can be extended using connection cables. Note that 5-pin connection cables
must be used for the sensors. When connecting an IO-Link master on the control side, a 4-pin connection
cable must be used.
Direct Wiring
As an alternative to using the adapter, wiring can also be done directly via terminal blocks or within a con-
troller. To do this, connect the sensors according to the following wiring diagram. The operating modes
must be set manually in each sensor.

*1'6HFRQGDU\
The example shows the use of 2 digital sensors. In this case, switching points can be set via pins 2 and 4
on the main sensor based on the calculated difference or thickness. Two analog sensors or a combina-
tion of digital and analog sensors can also be used. In that case, the calculated thickness can then be
tapped as an analog signal at the analog output of the main sensor.
Page 35
8 ‒ Function Description | P3PC341 ‒ Laser Distance Sensor Triangulation 35
NOTICE
Sensors with different measuring ranges can also be combined. In this case, the respective working
ranges must be taken into account during installation.
A combination of versions with red and blue lasers is also possible. This combination is recommended if,
due to the installation situation, the sensors interfere with each other when no object is present.
Calibration
To perform thickness or differential measurements, the system must be referenced after mechanical as-
sembly and wiring.
During this process, the sensors automatically calibrate their distances from one another so that the mea-
surement results can be calculated according to the setup. Calibration can be performed via the teach-in
key or Enter button, via the OLED menu, Bluetooth, or via IO-Link.
The reference object must be positioned in the measuring system according to the mechanical setup. For
referencing via the teach-in key, hold it down for 10 seconds until the two LEDs begin to flash. Then re-
lease the key. The LEDs will flash twice briefly to confirm. The sensors are now referenced.

Outputs
If a sensor is in the Main Thickness/Difference mode of operation, the calculated thickness or difference is
used for output at the outputs.
SSC1/SSC2
All settings can be configured identically to standalone operation. However, the switching points do not
correspond to a distance, but rather to the thickness/difference. The switching points are set via separate
parameters. All other settings are configured using the general parameters of SSC1/SSC2.
Analog output
In this operating mode, the analog output functions exclusively in tolerance mode. The reference value
corresponds to 12 mA or 5 V at the analog output. The tolerance range and characteristic can be set via
separate parameters.

8.8.3 Simulation Functions
This function simulates the behavior of the sensor regardless of the current status and measured value.
This can be used to check whether a plant in which the sensor is integrated reacts correctly to the data
supplied by the sensor and processes them accordingly.
If a measured value is specified, the sensor behaves as if the specified measured value corresponds to
the actual measured value. This means that the behavior of the outputs and status messages is simulated
according to the specified measured value.
In addition, the individual outputs and status messages can be simulated separately from the measured
