7.2.1 Meaning of the 7@segment display during alignment
During alignment, the 7@segment display on the receiver shows you when the optimal
alignment is achieved (see Tab. 22).
• The beam that is closest to the 7@segment display is termed the first light beam
(see Fig. 38 and Fig. 39).
• Only the first and last light beam are evaluated during alignment.
• If the optimum alignment (= no display) persists for longer than 2 minutes without the
multiple light beam safety device being interrupted, the system automatically
deactivates the alignment mode.

Only the last light beam is aligned.
All the light beams hit the receiver, but the alignment is still slightly
off.
No indication and

The alignment is now true; the devices must be locked in this
position.
