Disassembly and disposal

Table 13: Troubleshooting
LED indicator/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
No object in beam path, no out‐
put signal
Yellow LED flashes; if Health is
present then take note of the
corresponding output signal; if
Alarm is present then take note
of the corresponding output
signal
Yellow LED lights up, no object
in the path of the beam
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).
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Test input (Test) is not con‐
nected properly
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal/addition‐
ally with health output: power
supply interrupted
The beam of light of a photo‐
electric through-beam sensor
hits the receiver of another
(neighboring) photoelectric
through-beam sensor
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 connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Check the operating condi‐
tions: Fully align the beam of
light (light spot) with the
receiver. / Clean the optical
surfaces / If the potentiome‐
ter is set to the max. sensitiv‐
ity: Reduce the distance
between the sender and the
receiver chapter 7 / Check
sensing range and adjust if
necessary, see figures in
chapter 7. / With health out‐
put: Check the voltage supply,
check all electrical connec‐
tions (cables and plug connec‐
tions).
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.
