Alignment of the safety light curtain
Secure the system. No dangerous state possible!
Ensure that the dangerous state of the machine is (and remains) switched off! During the
alignment process, the outputs of the safety light curtain are not allowed to have any
effect on the machine.
After the safety light curtain has been mounted and connected, the two Twin Sticks must
be aligned in relation to each other. The light beams emitted by the sender optics must hit
the receiver optics accurately.
The miniTwin2 safety light curtain signals the alignment quality with the aid of the blue
LEDs (1 to 5), i.e. how well the two Twin Sticks are aligned with each other. If all LEDs
illuminate, the alignment is optimal, if no LED illuminates, the alignment is poor.
If three of the blue LEDs illuminate, then the safety light curtain changes to green. You
then have approx. 2 minutes to optimize the alignment of the Twin Sticks.
