c Adjusting the feeder float sensor on the transport side
1) Turn the volume on the light emission side counterclockwise to the minimum position to put the
sensor in the shut-down state.
2) Gradually turn the volume clockwise toward the maximum position and stop turning when both
the red and green lamps on the light receiving side are lit.
3) Set the NF12 at the left, center, and right positions of the bank. Open and close the front cover
to check that the sensor is turned OFF.

∗ If the sensor is not turned OFF even though the font cover is opened, the sensor mounting
position may deviate in the Y-direction. If this occurs, loosen the sensor mounting screws and
move the sensor back and forth.
4) If the sensor mounting position is changed in work step 3), adjust the light axis and perform the
adjustment again from step 1).
(The above adjustments are absolutely necessary since the volume adjustment amount is
changed as the sensor position is moved.)
5) Put the NF16N in the same manner as described for step 3) to check that the sensor is turned
OFF.
∗ If the sensor is not turned OFF even though the font cover is opened, the sensor mounting
position may deviate in the Y-direction. If this occurs, loosen the sensor mounting screws and
move the sensor back and forth. (Normally, move the sensor toward the transport side.)
6) If the sensor mounting position is changed in work step 5), adjust the light axis and perform the
adjustment again from step 1).
(The above adjustments are absolutely necessary since the volume adjustment amount is
changed or the sensor is not turned ON or OFF correctly with NF12 as the sensor position is
moved.)

7) Check that a shielding object with a height of 35.6 mm from the bank support and bank
connection surface does not turn ON the sensor and that a shielding object with a height of
36.0 mm turns ON the sensor.
∗ If a shielding object with a height of 35.6 mm turns ON the sensor, remove the FSD spacer
(E2157729000) and insert the shim. Conversely, if a shielding object with a height of 36.0 mm
does not turn ON the sensor, insert the shim. (At this time, pay special attention so that the
position in the Y direction does not deviate.) After the shim has been inserted, check the height
again and make the adjustment again from step 1).

d Adjusting the feeder float sensor outside the machine
1) Turn the volume on the light emission side counterclockwise to the minimum position to put the
sensor in the shut-down state.
2) Gradually turn the volume clockwise toward the maximum position and stop turning when both
the red and green lamps on the light receiving side are lit.
3) Set the bulk feeder at the left, center, and right positions of the bank to check that the sensor is
not turned OFF.
∗ If the sensor is turned ON (green lamp does not light up correctly), turn the volume to make the
green lamp lit.
4) Set the NF32 feeder at the same positions as described in step 3) and open the top cover by
hand to check that the sensor is turned OFF when the top cover is raised 10 mm or less.
Raise the cover by hand.

∗ If the volume is turned excessively in step 3), the sensor does not respond even though the
cover of the NF32 feeder is opened.
5) Set the NF16 feeder at the same positions as described in step 3) and open the top cover using
the lever to check that the sensor is turned OFF.
