Subject to change without notice
LED/fault pattern
No object in beam path, no
output signal
Yellow LED flashes
Yellow LED lights up, although
an object is 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).

• 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

DISASSEMBLY AND DISPOSAL
Cause
Test input (Test) is not con‐
nected properly
Distance between sender
(WS) and receiver (WE) is
too large / Beam of WS is
not completely on WE or WE
is not aligned to WS / Front
screen and/or reflector is con‐
taminated.
The beam of light of a pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor

Measures
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
Check sensing range / Clean‐
ing of the optical surfaces.
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
