LED indicator/fault pattern Cause Measures
Yellow LED flashes 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
Check sensing range, see

yellow LED lights up, although
an object is 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
