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.
OPERATING INSTRUCTIONS
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Excessive background remis‐
sion
Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long
Remission capability of the
object is insufficient

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
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
object / Clean the optical sur‐
faces / Readjust the sensitiv‐
ity (potentiometer)
Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Increase the sensing range,
take note of the distance
between the sensor and the
background
Increase the sensing range,
take note of the distance
between the sensor and the
background
