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.
OPERATING INSTRUCTIONS
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 S | GSE6V
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 / Readjust the sensi‐
tivity (potentiometer) / If the
potentiometer is set to the
max. sensitivity: Reduce the
distance between the sender
and the receiver/ Check sens‐
ing range and adjust if neces‐
sary,
see table
4.
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
figure
