Beam-Axis Alignment - Panasonic SF4C Series Quick Instruction Manual

7. 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 the receiver are OFF respectively.
If the digital error indicator (red) or the fault indicator (yellow) lights up or blinks, refer to "
9. Troubleshooting" and report the symptoms to the maintenance in charge.
3. Loosen the hexagon-socket head bolts [M5 (purchase separately)] which holds the stan-
dard mounting bracket MS-SFC-1.
4. Move the emitter in the left and right directions in
order to determine the range of the light received
condition with the help of the beam-axis alignment
indicator (red). Then, set the emitter at the center
of this range.
5. Similar to the step 4, perform the beam-axis align-
ment for the receiver.
6. Tighten the standard mounting bracket MS-SFC-1
by the hexagon-socket head bolt [M5 (purchase
separately)].
7. Confirm that the beam-axis alignment indicators
(green) in the display of the emitter and receiver,
operation indicator (green) and OSSD indicator
(green) 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 align-
ment indicator blinks in red.

When all the 4 beam channels divided into each section are received, the beam-axis alignment indica-
tor 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 re-
ceived and the control output (OSSD 1 / 2) turns ON, all the four indicators of the beam-axis alignment
indicator turn into green.
