Figure 9: Sensing range area
Use see table 3, page 8 to check the function. If the switching output fails to behave in
accordance with the table, check the application conditions. See section Fault diagnosis.
3 Sensitivity setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 4: Troubleshooting
LED indicator/fault pattern Cause Measures
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 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 lights up, no object
in the path of the beam The beam of light of a pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor 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 1, page 6
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).
