Subject to change without notice
The sensor is adjusted and ready for operation.
NOTE
Do not operate the teach-in button using sharp objects.
The sensing range can be adjusted via IO-Link. Please refer to the enclosed "IO-Link
photoelectric sensors" operating instructions for information.
The Troubleshooting table indicates measures to be taken if the sensor stops working.

LED/fault pattern
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
Green LED flashes
Digital outputs not according to
graphic
Digital outputs not according to

Yellow LED lights up, no object
in the path of the beam
Object is in the path of the
beam, yellow LED does not
light up
The sensor must be disposed of in line with applicable country-specific regulations.
When disposing of them, you should try to recycle them (especially the precious met‐
als).
NOTE
Disposal of batteries, electric and electronic devices
•
According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
• The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
IO-Link communication
IO-Link communication
Parameter settings made
manually, which deviate from
the standard
The sensing range distance is
too large
Distance between the sensor
and the object is too long or
sensing range is set too short

COMMISSIONING
Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor

-
Initiate a factory reset. The
digital outputs are reset to
factory settings.
