LED indicator/fault pattern Cause Measures
Green LED lights up, no output
signal when ob

Yellow LED flashes Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
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 6.
Yellow LED lights up, no object
in the path of the beam
The beam of light of a photo‐
electric through-beam sensor
hits the receiver of another
(neighboring) photoelectric
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 10.
8 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).
