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,
