Subject to change without notice
LED/fault pattern
Switching outputs do not
behave in accordance with
table 4
WTS only: yellow LED flashes
quickly
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.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
This SICK sensor is maintenance-free.
We do, however, recommend that the following activities are undertaken regularly:
• Clean the optical interfaces using a plastic cleaner, do not use acetone or methy‐
lated spirits.
•
Check the fittings and plug connectors
No modifications may be made to devices.

DISASSEMBLY AND DISPOSAL
Cause
1. Change of the configuration
2. Short-circuit
When adjusting the sensing
range, the light spot is only
half on the object or on a very
high-contrast object
The sensing range distance is
too large
Distance between the sensor
and the object is too long or
sensing range is set too short
