7.4.1
Aligning the sender and receiver
Important information
DANGER
Dangerous state of the machine
b
Make sure that the dangerous state of the machine is (and remains) switched off
during the alignment process.
b
Make sure that the outputs of the safety light curtain do not affect the machine
during the alignment process.
Prerequisites
•
Sender and receiver have been mounted correctly
Approach
1.
Switch on the voltage supply for the safety light curtain.
2.
Roughly align the sender with the receiver: Rotate the sender so that it points
toward the receiver.
3.
Align the receiver with the sender: Rotate the receiver so that as many blue
alignment quality light emitting diodes as possible light up on the receiver.
4.
If required, align the sender more precisely with the receiver so that as many
alignment quality light emitting diodes as possible light up on the receiver.
5.
If required, align the receiver more precisely with the sender so that as many
alignment quality light emitting diodes as possible light up on the receiver.
6.
When at least three (preferably four) alignment quality LEDs light up on the
receiver, fasten the components in the brackets. Torque: 2.5 Nm ... 3 Nm.
7.
Switch the voltage supply off and then on again.
8.
Check the alignment quality light emitting diodes to make sure that the compo‐
nents are still correctly aligned with each other.
NOTE
Once 3 blue alignment quality light emitting diodes light up, alignment is good and
availability is stable.
Please note that body parts or objects in the protective field (e.g., hand, tool, AR60
optional laser alignment aid) may impair the function of the alignment quality LEDs.
Remove all objects from the protective field to allow the alignment quality to be
assessed.
Complementary information
The AR60 optional laser alignment aid can be used to facilitate alignment.
Since the AR60 optional laser alignment aid is positioned in the protective field of the
safety light curtain with the adapter, a maximum of two blue alignment quality LEDs
light up and the OSSD LED lights up red. To check whether the OSSD LED of the
receiver lights up green, remove the AR60 optional laser alignment aid.
