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
No object in beam path, no out‐
put signal
Green LED flashes
Digital outputs not according to
graphic
Digital outputs not according to
graphic
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 in line with applicable country-specific regulations.
When disposing of them, you should try to recycle them (especially the precious met‐
als).
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Test input (Test) is not con‐
nected properly
IO-Link communication
IO-Link communication
Parameter settings made
manually, which deviate from
the standard
Sensor is still ready for oper‐
ation, but the operating con‐
ditions are not ideal/addition‐
ally with health output: power
supply interrupted
The beam of light of a pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor

OPERATING INSTRUCTION
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.

Initiate a factory reset. The
digital outputs are reset to
factory settings.
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 section 1.8.2 / Check
sensing range and adjust
if necessary, see figures in
section 1.8.2. / With health
output: Check the voltage sup‐
ply, check all electrical con‐
nections (cables and plug con‐
nections).
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 12.
