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.
Subject to change without notice. Specified product properties and technical data are
not written guarantees.
Cause
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Depolarizing property of the
object surface (e.g., tape),
reflection
Measures
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor)./ If the potentiometer is
set to the max. sensing range:
Reduce the distance between
the sensor and the reflector,
and check the reflector type /
Reflector is not suitable for
the application in question
(we recommend only using
SICK reflectors) / Check sens‐
ing range and adjust if neces‐
sary. / Distance between the
sensor and the reflector is too
long
Reduce sensitivity or change
the position of the sensor
