LED indicator/fault pattern Cause Measures
Sensor is faulty If the power supply is OK,
replace the sensor
Green LED flashes IO-Link communication -
Switching outputs do not
behave in accordance with
table 5
IO-Link communication None
Change of the configuration Adjustment of the configura‐
tion
Short-circuit Check electrical connections
Yellow LED flashes 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.
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
Signal interruptions when
object is detected
Depolarizing property of the
object surface (e.g., tape),
reflection
Reduce sensitivity or change
the position of the sensor
9 Disassembly and disposal
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.
10 Maintenance
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.
