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.
This SICK sensor is maintenance-free.
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Test input (Test) is not con‐
nected properly
IO-Link communication
IO-Link communication
Parameter settings made
manually, which deviate from
the standard
The sensor is not ready for
operation. The sensor will be
in the warming-up phase at
low ambient temperatures.
The sensor will have shut
down at excessively high
ambient temperatures.
Distance between the sensor
and the background is too
short
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
See the note on connecting
the TI
-
-
Initiate a factory reset. The
digital outputs are reset to
factory settings.
At low ambient temperatures,
wait until the sensor has
warmed up. Ensure the sensor
cools down at excessively high
ambient temperatures.
Check the teach-in mode
Reduce the sensing range,
see graphic F
Increase the sensing range,
