Aligning sender and receiver

After all parts have been mounted and connected, the related sender
and receiver must be aligned.
How to align sender and receiver in relation to each other:
Secure the plant/system. No dangerous state possible!
Make sure that the dangerous state of the machine is (and remains)
switched off! During the alignment process, the outputs of the L4000
system are not allowed to have any effect on the machine.
= Disconnect the wire at pin 13 on the safety evaluation device
UE401 or at pin 4 on the first sensor. In this way you increase the
intensity of the light emitted by this and the other senders and
make the alignment process easier.
= Always start the alignment by aligning the first pair in the chain, as
otherwise the subsequent senders cannot emit any light.
= Align sender and receiver as accurately as possible and fix both
temporarily in position.
= Switch on the power supply for the L4000 system.
= Place a piece of white paper or reflective film 100 mm x 100 mm
with hole (sensor cross-section) centrally on the receiver.
= Align the sender with the receiver until the reflected light on the
reflector is at the maximum intensity.
= Ensure that the yellow LED on the receiver is illuminated, or correct
the receiver as appropriate.
= To check the intensity, partially cover the sender and/or receiver
lens. The intensity of the light beam received is adequate when the
LED on the receiver only starts to flash when at least half the area
of the lens is covered.
= Fix the sensors in this position.
= Proceed in the same way with the other sensors.
= Connect pin 4 on the first sender (black wire) or the related wire
(pin 13) to the safety evaluation device UE401.
