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 multiple light beam safety device do not affect
the machine during the alignment process.

8.4.1
Aligning the active and passive units
Prerequisites
•
Active and passive units have been mounted correctly
•
The light path is free of objects. Neither objects nor body parts (e.g. hand, tool,
optional AR60 laser alignment aid) are in the light path.
Approach
1.
Ensure that the active and passive units can rotate in the brackets. If necessary,
loosen the fixing screws slightly.
2.
Switch on the voltage supply to the active unit.
3.
Roughly align the active unit with the passive unit: Turn the active unit so that it is
pointing toward the passive unit.
4.
Align the passive unit with the active unit: Turn the passive unit so that as many
blue diagnostic LEDs as possible light up on the active unit.
5.
If necessary, align the active unit more precisely with the passive unit so that as
many diagnostic LEDs as possible light up on the active unit.
6.
If necessary, align the passive unit more precisely with the active unit so that as
many diagnostic LEDs as possible light up on the active unit.
7.
In a system with 2 light beams: If at least 3 (better: 4) of the diagnostic LEDs
1 … 4 light up on the active unit, fix the components in the brackets. Torque: 2.5
Nm ... 3 Nm.
8.
In a system with 4 light beams: If at least 3 (better: 4) of the diagnostic LEDs
1 … 4 and at least 3 (better: 4) of the diagnostic LEDs 5 … 8 light up on the active
unit, fix the components in the brackets. Torque: 2.5 Nm ... 3 Nm.
9.
Switch the voltage supply off and back on again.
10. Check the diagnostic LEDs for the alignment quality to make sure that the compo‐
nents are still correctly aligned with each other.
Complementary information
The optional AR60 laser alignment aid can make performing the alignment even easier.
It can be mounted on the active unit and on the passive unit for short scanning ranges.
To ensure that the indication of the alignment quality cannot be impaired, place the
AR60 optional laser alignment aid with the adapter between the light beams of the mul‐
tiple light beam safety device.

Prerequisites
•
The active and passive units are each mounted using a QuickFix bracket
