8.4.3 Indication of the alignment quality
Important information
NOTE
As soon as the diagnostic LEDs 1, 2 and 3 light up, the alignment is good and availabil‐
ity is stable.
Body parts or objects in the protective field (e.g., hand, tool, AR60 optional laser align‐
ment aid) may impair the indication of the alignment quality (at most diagnostic LEDs 1
and 2 light up).
b
Ensure that no body parts or objects are in the protective field
Or

W
atch out for diagnostic LEDs 5, 6, 7 and 8. If diagnostic LEDs 5, 6, 7 and 8 light
up, the alignment is good and availability is stable.
Indication of the alignment quality
Position of LEDs: see "R
eceiver indicators", page 19.
If front screen contamination increases in ongoing operation, the laser alignment aid
switches on or the alignment takes longer than 3 seconds, the receiver shows the align‐
ment quality again.
Once the safety light curtain is aligned and the protective field is clear (field indicator:
flashing yellow or lit up green), the alignment quality display switches off after a certain
period of time.
