LED indicator/fault pattern Cause Measures
Switching outputs do not

1. Change of the configuration
2. Short-circuit
1. Adjustment of the configura‐
tion
2. Check electrical connections
WTS only: yellow LED flashes
quickly
When adjusting the sensing
range, the light spot is only
half on the object or on a very
high-contrast object
Sensing range setting accord‐
ing to„WTS16 sensing range
setting“, page 12
Yellow LED lights up, no object
in the path of the beam
The sensing range distance is
too large
Reduce the sensing range
Object is in the path of the
beam, yellow LED does not
light up
Distance between the sensor
and the object is too long or
sensing range is set too short
Increase the sensing range
10 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.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
11 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.
