2. For Your Safety
2.1 Use for Intended Purpose
This wenglor product is intended for use in accordance with the following functional principle:
Reflex light barrier
The reflex light barriers work with red light and detect objects both via the intensity of the backscattered light
and via the distance to a previously taught-in reference background. If the light beam between the sensor and
the reference background is interrupted, the output is switched. Thanks to the combined detection principle,
the sensors are suitable for contactless object detection without a reflector, regardless of color, shape, or
surface.

engineering
• Heavy mechanical engineering
• Logistics
• Automotive industry
• Food industry
• Packaging industry
• Pharmaceuticals industry

• Observe all applicable electrical and mechanical regulations, standards, and safety rules.
• Protect the product against mechanical influences.
• Make sure that the sensor is mounted in a mechanically secure fashion.
• Specified torque values must be complied with (see “3. Technical Data” on page 7).
ATTENTION!
Risk of property damage in case of improper installation!
The product may be damaged.
• Installation instructions must be complied with.
CAUTION!
Risk of personal injury or property damage during installation!
Personal injury and damage to the product may occur.
• A safe installation environment must be assured.

12 Installation and Electrical Connection
The following must be observed when installing reflex light barriers
Background Colors
For reliable detection, there must be a clear contrast
between the object and the taught-in reference back-
ground.
Tip: If there is a small difference in contrast, select
a large distance between the object and the backg-
round!
Highly glossy, reflective and uneven back-
grounds
In the case of highly reflective, glossy or uneven
surfaces, it should be ensured that no direct reflec-
tions fall on the receiving optics, as they can impair
object detection.
Tip: Place the sensor at a slightly tilted angle!
Steps, edges and recesses
To ensure reliable detection, the light spot must be
aligned directly with the reference background.
Tip: Align the sensor to a specified background!
Moving background
For moving reference backgrounds such as con-
veyor belts, the movement should be perpendicular
to the transmitter/receiver axis of the sensor to avoid
direct reflections on the receiver.
Tip: Install the sensor orthogonally!

occur.
• Required action as specified in case of fault.
6. Settings
6.1 Teach-in on a static background (default P1PM101/P1PM102)
Object detection against a static reference background such as a stainless steel machine part
The sensor is taught in such that it demonstrates stable switching performance despite interference such as
vibration.
• Install the sensor in accordance with the installation instructions.
• Align the sensor to the reference background.
• Press and hold the teach-in key until switching status indicator LED A1 starts flashing slowly (2 Hz) after 2
seconds.
• Release the teach-in key.
• The sensor first automatically adjusts the intensity of the red light to the chosen reference background.
• The sensor briefly analyzes the signals received and uses them to calculate the switching thresholds (light
intensity and distance).
• The switching thresholds are taught in and the LED for A1 flashes twice in order to confirm successful
teach-in. If teach-in has not been successful, LED A1 flashes 4 times. If this is the case, the procedure
must be repeated.

16 Settings
6.2 Teach-in on a moving background (default P1PM103/P1PM104)
Object detection in front of moving reference background such as moving conveyors The sensor is taught in
such that, depending on the application, minimal thresholds can be set in order to detect smallest possible
parts by means of this process. With running conveyor belt, the sensor is set to a signal analysis phase which
is started and stopped on an application-specific basis. The receive signals are analyzed during this time and
the switching thresholds are calculated based on this analysis. And thus application-specific receive signals do
not result in erroneous sensors switching.
• Install the sensor in accordance with the installation instructions.
• Align the sensor to the reference background (conveyor belt).
• Press and hold the teach-in key until switching status indicator A1 starts flashing rapidly (4 Hz) after 2 sec-
onds.
• Release the teach-in key.
• The sensor automatically adjusts the intensity of the red light to the chosen reference background.
• The recording phase begins, while the red light of the sensor and the LED for A1 flash rapidly
(4 Hz).
• The sensor analyzes the received signals and computes adapted switching thresholds based on these
analyses.
• Pressing the button again ends the recording phase.
• The calculated switching thresholds are taught in and the LED for A1 flashes twice in order to confirm suc-
cessful teach-in. If teach-in has not been successful, LED A1 flashes 4 times. If this is the case, the proce-
dure must be repeated.
NOTE!
The max. recording phase is 1 minute (teach-in on moving background). If the recording
phase is not ended by pressing the button a second time, an error message is displayed
and the process must be repeated.
NOTE!
If the sensor is used above a conveyor belt, it’s advisable to activate the belt during the
recording phase. Height fluctuations, impacts, belt seams contamination, etc. are analyzed
as a result and made use of when calculating the switching thresholds. Erroneous switching
due to the conveyor belt can be avoided in this way.

7. Functions Overview
Further settings can be entered into the sensor via the IO-Link.
7.1 Teach-In Mode
Both operating modes can be set via IO-Link for reliable object detection against a static or moving backg-
round. This allows both modes to be tested to optimally adapt the sensor to the application. Setting two sepa-
rate teach-in modes offers the advantage that extremely flexible and simple teach-in of reflex light barriers is
possible. There is also the option of selecting a pre-set variant.
Teach-in on a static reference background
• Object detection against a static reference back-
ground such as a stainless steel machine part
• Teach-in on the background takes place at the
touch of a button
• Visual confirmation via status LEDs when teach-in
is successful
Teach-in on a Moving Reference Background
• Object detection in front of moving reference
background such as moving conveyors
• Teach-in on moving background by pressing the
button for application-specific teach-in sequence
• Compensation of vibrations, contamination and
unevenness through automatic adjustment of the
sensor during teach-in

18 Functions Overview
Dynamic Readjustment
Continuous readjustment of the switching threshold of the sensor. The time interval for readjustment can be
set on the interface. This function is activated upon shipment from the factory.

9. Maintenance Instructions
NOTE!
• This wenglor sensor is maintenance-free.
• Cleaning and inspection of the plug connections at regular intervals are advisable. After
cleaning the sensor and/or reference background, the sensor may require a new teach-in
process. This depends largely on the level of contamination in the application.
• Do not clean the sensor with solvents or cleaning agents that could damage the product.
• The product must be protected against contamination during initial start-up.
