Maintenance

8020358.19RH / 15.01.2021 | SICK
Subject to change without notice
LED indicator/fault pattern
Switching outputs do not
behave in accordance with
table 5
Not all blue LEDs light up.
No object in beam path, no
output signal
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.
•
WEEE: 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.
DISASSEMBLY AND DISPOSAL
Cause
1. Change of the configuration
2. Short-circuit
a) Insufficient alignment
b) Contamination of the opti‐
cal surfaces
c) Particles in the light beam
d) Distance between sender
(WS) and receiver (WE) is
too large
Test input (Test) is not con‐
nected properly
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 pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor
Measures
1. Adjustment of the configura‐
tion
2. Check electrical connections
a) Check alignment
b) Cleaning of the optical sur‐
faces.
c) Avoid contamination in the
air as far as possible
d) Check sensing range
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
Check sensing range, see
figure 5
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
