LED/fault pattern
Yellow LED does not light up
even though the light beam
is aligned to the receiver and
there is no object in the path of
the beam
Yellow LED flashes
Yellow LED lights up, no object
in the path of the beam
The sensor must be disposed of in line with applicable country-specific regulations.
When disposing of them, you should try to recycle them (especially the precious met‐
als).
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 and housing
• Check the fittings and plug connectors
OPERATING INSTRUCTION
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
The beam of light of a pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor
O P E R A T I N G I N S T R U C T I O N | GSE6L
Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
receiver. / Clean the optical
surfaces / If the potentiom‐
eter is set to the max. sen‐
sitivity: Reduce the distance
between the sender and the
receiver / Check sensing
range and adjust if necessary
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 : see
