LED indicator/fault pattern
Yellow LED flashes
yellow LED lights up, although
an object is in the path of the
beam.
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
Distance between sender
(WS) and receiver (WE) is too
large / Beam of WS is not
completely on WE or WE is not
aligned to WS
The beam of light of a photo‐
electric through-beam sensor
hits the receiver of another
(neighboring) photoelectric
through-beam sensor
Measures
Check sensing range, see fig‐
ure 6
Check alignment
Swap the sender and receiver
arrangement at every sec‐
ond through-beam photoelec‐
tric sensor and ensure that
there is sufficient distance
between the through-beam
photoelectric sensors, see
figure 1
