Step 3 To align using the LEDs, watch the receiver alignment LEDs on the
receiver unit as you tighten in turn each of the 4 M16 adjusting
screws.
Note:
The LEDs flash according to the direction of the adjustment.
The first and fifth LEDs will illuminate when a large change in
alignment has occurred, whereas, the second and fourth LEDs will
illuminate when a small change in alignment has occurred (either
positive or negative
–
see Figure 7-29).
The first and fifth LEDs will remain illuminated when the photodiode
DC level has exceeded a pre-set voltage threshold and adequate
alignment is achieved.
