The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
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.
•
This symbol on the product, its package or in this document, indicates
that a product is subject to these regulations.
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•
Clean the external lens surfaces
•
Check the screw connections and plug-in connections
No modifications may be made to devices.
Subject to change without notice. Specified product properties and technical data are
not written guarantees.
Cause
Sensor is faulty
IO-Link communication
IO-Link communication
Change of the configuration
Short-circuit
Distance between sensor and
reflector is too large / light
beam is not completely
aligned to the reflector /
reflector is not suitable/Front
screen and/or reflector is con‐
taminated.
Depolarizing property of the
object surface (e.g., tape),
reflection
Measures
If the power supply is OK,
replace the sensor
-
None
Adjustment of the configura‐
tion
Check electrical connections
Check the operating condi‐
tions: Fully align the beam of
light (light spot) with the
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor). / Reflector is not suitable
for the application in question
(we recommend only using
SICK reflectors) / Check sens‐
ing range and adjust if neces‐
sary
Reduce sensitivity or change
the position of the sensor
