NOTE
Do not operate the teach-in button using sharp objects.
The sensor is adjusted and ready for operation.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 6: Troubleshooting
LED/fault pattern Cause Measures
Yellow LED does not light up
even though the light beam
is aligned to the reflector and
there is no object in the path of
the beam No voltage or voltage below
the limit values Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor). / 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
Signal interruptions when
object is detected Depolarizing property of the
object surface (e.g., tape),
reflection Reduce sensitivity or change
the position of the sensor
9 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,
