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

Yellow LED flashes
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
Notes on malfunctions can be found in the service data.
Details of the available service data can be found in the detailed IO-Link description:
Technical Information: Photoelectric sensors, SICK Smart Sensors /
All IO-Link devices have a backup and restore functionality - Data Storage (DS). The
IO-Link Data Storage function can be used to save previous parameters and transmit
them to the replacement device.
The prerequisite for this is connection of the device to an IO-Link Master, and activation
of the storage function in the IO-Link Master.
Details on sensor replacement can be found in the detailed IO-Link description:
cal Information: Photoelectric sensors, SICK Smart Sensors /
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
When adjusting the sensing
range, the light spot is only
half on the object or on a very
high-contrast object
The sensing range distance is
too large
Distance between the sensor
and the object is too long or
sensing range is set too short
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.
Sensing range setting accord‐
ing to section 6.3
Reduce the sensing range
Increase the sensing range
