3) Adjust the height of a newly mounted sensor.
Adjust the height of the top surface of the FSD bracket to 126.6±0.1 mm from the top surface of
the feeder bank, and secure it.
However, adjust the height of the FSD bracket with a set of left and right sensors (light
receiving and light emission) so that a difference in height is
0.1 mm or less.

4) Adjust the light axis.
c Connect the connectors of the sensors to their specified positions and turn on the power to
the main unit.
d Move the light emission and light receiving sensors so that the light axis is matched.
When the light axis is adjusted correctly, both the red and green LEDs on the light receiving
sensor will light up.
(The red LED is the operation indicator lamp and the green LED is the stability indicator
lamp.)
∗ For the FSD bracket assembly, adjust the light axis of two sensors.
