angerous 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.
NOTE
Dur
ing the alignment, observe the alignment quality indication and the bracket that is
used to attach the twin sticks.

8.4.1 Aligning the twin sticks to one another
Overview
Af
ter the safety light curtain has been mounted and connected, the two twin sticks
must be aligned with each other. The beams of the sender optics must met exactly on
the receiver optics.
The miniTwin4 safety light curtain signals the alignment quality with the blue LEDs (1 to
5), i.e. how well the two twin sticks are aligned with each other. If all LEDs light up, then
alignment is optimal; if no LEDs light up, alignment is poor.
If 3 of the blue LEDs light up, the safety light curtain switches to green. From this point
in time, you have about 2 minutes to optimize the alignment of the twin stick.
