9.2.1 Meaning of the 7Gsegment display during alignment
During alignment, the 7Esegment display on the receiver shows you when the optimal
alignment is achieved (see Tab. 37).
The beam that is closest to the 7Esegment display is termed the first light beam
(see Fig. 59 and Fig. 60).
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
m
ultiple light beam safety device being interrupted, the system automatically deacti-
vates the alignment mode.
M4000 Advanced and M4000 Area 60/80
Display Significance during alignment
First and last light beam not aligned.
Only the first light beam is aligned.
Only the last light beam is aligned.
All the light beams hit the receiver, but the alignment is still slightly
off.
No indication and
green LED
illuminated on the
receiver
The alignment is now true; the devices must be locked in this
position.
