5. and adjust the emitter / receiver so that the beam-axis alignment indicators in the display of the emitter
and receiver light up.
The emitter and the receiver can be fine-adjusted by ±5 degrees.
6. After the adjustment, tighten the hexagon-socket head bolt for beam-axis alignment of the multifunctional
mounting bracket.
The tightening torque should be 2N·m or less.
7. Tighten the hexagon-socket head bolt of the multifunctional intermediate supporting brackets [M3 (length:
5 mm)].
8. Confirm that the beam-axis alignment indicators (green) in the display of the emitter and receiver,operation
indicator (green) and OSSD (green) indicator light up.
<Reference>
The beam-axis alignment indicator indicates the reception status for each section of the device which is divided into 4
sections.
Furthermore, the A (D) of the beam-axis alignment indicates the light-receiving status of the device top end (bottom end).
For example, when using a 16-beam channel device, there are 4 beam channels per section (i.e., 16/4=4).
When the top end (bottom end) beam channel is received, the A (D) of the beam-axis alignment indicator blinks in red.

When all the 4 beam channels divided into each section are received, the beam-axis alignment indicator lights up in red.
The indicators corresponding to the different sections light up in red, one by one, when the beam channels of the re-
spective sections are received. When all the beam channels are received and the control output (OSSD 1 / 2) turns ON,
all the four indicators of the beam-axis alignment indicator turn into green.
Refer to "2-6-2 Operation Test" for details.
After beam-axis alignment, confirm that all bolts are tightened at stated torque. Refer to "2-4 Mounting"
for each tightening torque of the bolts.
