Adjustment; Beam-Axis Alignment - Panasonic SF2B Series Instruction Manual

2-6 Adjustment

2-6-1 Beam-axis Alignment

1. Turn ON the power supply unit of this device.
2. Check that the digital error indicator (red) and the fault indicator (yellow) of the emitter and
receiver are OFF respectively.
If the digital error indicator (red) or the fault indicator (yellow) lights up or blinks, refer to
"Chapter 5 Troubleshooting," and report the symptoms to the maintenance in charge.
3. Loosen the hexagon-socket head bolts of the standard mounting bracket (MS-SF2B-1) (op-
tional), and align the emitter and receiver to the position where the beam-axis alignment in-
dicator lights up. The angle of the emitter / receiver can be adjusted ±15°.
<Reference>
The beam-axis alignment indicator indicates the reception status for each section of the device which is
divided into 4 sections.
Also, 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 32-beam channel device, there are 8 beam channels per section (i.e., 32/4=8).
When the top end (bottom end) beam channel is received, the A (D) of the beam-axis alignment indicator blinks in red.

All the 8 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 respective 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 "2-6-3 Operation" for details.
4. After the adjustment, tighten the hexagon-socket head bolts of the standard mounting brack-
et. The tightening torque should be 0.6N·m or less.
