LED indicator/fault pattern
Yellow LED does not light up
even though the sender is
aligned to the object and the
object is within the set sensing
range
Yellow LED flashes; if Alarm /
Health is present then take
note of the corresponding out‐
put signal
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
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 recommends the following regular maintenance:
• Clean the external optical 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
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Stray background remission
Object remission is too low
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
Check the background for
highly reflective objects and
try to block from the sensors
field of view
Reduce distance between
sensor and object. Note that
the object may not have
enough remission for detec‐
tion.
