4. Adjust the emitter / receiver so that the beam-axis alignment indicators in the display of

the emitter and receiver light up.

The beam-axis alignment indicator indicates the reception status for each section of a sensor which is divided into 4 sections.

Also, the A (D) of the beam-axis alignment indicates the light-receiving status of the sensor top end.

For example, when using a 16-beam channel sensor, 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.

(Example) 16 beam channels

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 respective sections are received. When all the beam channels are received and the control output

(OSSD 1, OSSD 2) turns ON, all the four indicators of the beam-axis alignment indicator turn into green.

For details, refer to '3-4-3 Operation'.

5. Tighten the hexagon-socket-head bolts [M3 (length 5mm)] for adjusting the mounting angle

at the top and the bottom of the emitter to fix the emitter. (Tightening torque: 0.6N·m or less)

If the intermediate supporting bracket has been mounted on the sensor main body, tighten the

hexagon-socket-head bolt [M4 (length 10mm)] for position adjustment. (Tightening torque: 1.8N·m or less)

6. Check, once again, that the beam-axis alignment indicators in the display of the emitter

and receiver do light up.
