[3-10] Board Sensor Adjustment
 1) Set the conveyor sensor amplifiers as shown below.
(At rear part-supply machines, the amplifiers are located on the right-side face of the MFU
mounting area. At front part-supply machines, the amplifiers are located in front of the
conveyor.)
 2) Adjust the ICM deceleration and arrival sensor positions with reference to the following
illustration.

Remarks
In cases where the board stopper pushes
boards which are being unloaded
upward, turn the arrival sensor's OFF-D
switch on and adjust the OFF-D volume.
If the OFF-D timer period is too long,
however, 2 consecutive boards will be
unloaded.

3) Adjust the machine's deceleration, arrival, and pass sensor positions with reference to the
following illustration. (This illustration shows a rear part-supply machine)
Note 1. Verify that that there is no interference between the pass sensor bracket and the
conveyor pulley (or belt) when the conveyor is adjusted to the minimum size board
width.
As old type brackets cannot be adjusted to 5mm, move these brackets to the end of the
slot.
Note 2. Because interference occurs if old type brackets are adjusted to 3mm, a change of up to
6mm is permitted.
4) Set the volume of the conveyor deceleration speed controller to 30%. Check to see if the
conveyor decelerates when the deceleration sensor beam is blocked.
5) Clamp a Fuji board (1.6mm thick, with black sensor activating face), and verify that the
deceleration, arrival, and pass sensors operate properly. If a sensor fails to activate, turn the
sensor's amplifier volume a little higher, stopping at the point where the sensor activates.
6) Set a premounted part on a Fuji board (board bottom face, height 23mm, with black sensor
activating face), and check to see if this part activates the deceleration and arrival sensors.
If a sensor fails to activate, turn the sensor's amplifier volume a little higher, stopping at the
point where the sensor activates. (For premounted parts with heights exceeding 23mm (23
to 26mm), move the sensor further back.) If the pass sensor fails to activate, adjust its
amplifier volume so that the pass sensor can detect a black color 26mm below the board's
bottom face.
7) Finally, verify that the sensors are not activated by the white board located 27mm above the
board clamper's top face. (Not activated by the mark camera's white dispersion plate.)
8) If the check results at steps 6) and 7) are NG, change the sensor height (pass sensor), then
repeat the above procedure, beginning from step 5). However, only the pass sensor height may
be changed. Only volume adjustment is permitted at the deceleration and arrival sensors.

[3-11 ] Conveyor Width Check
1) Lower the lifter table.
2) Verify that the conveyor width can be adjusted from the minimum (50mm) to maximum
(356mm) width in a smooth manner without interference.
[3-12] MFU Clamp Pin and Stopper Position Adjustments
Note: When detaching and moving the MFU, protect the cable.
(For example, keep the cable off the floor so that it does not get run over by the MFU
casters.)
1) Set MFUs at the machine, verifying that all MFUs can be set in a smooth manner.
2) Adjust the stopper bracket so that there is a 0.5mm gap between the urethane MFU stopper
and the MFU's end face.
[3-13 ] MFU IN/OUT Port Check
Mount a feeder (for an I/O check) at the MFU, then use I/O commands to check the operation
of all devices. [Ex] I/O X03C PART FED CMPLT, Y028 SEND PART D1
[3-14] Tape Leaf Sensor Adjustment
1) Set an MFU at the machine.
2) Mount device jigs at D19 and D21.
3) Insert bar jigs (1.8mm dia.) into both slits, then move the sensor until the bar jigs are
positioned in the center of the sensor beam. Partially tighten the sensor at that position.
4) Move the D19 jig to D1, and adjust the sensor receptor side in the same manner, partially
tightening it at this position.
5) Move the jig slits forward one side at a time and use the "IN X00E FDR DETECT" I/O
command to verify that the sensor switches off.
6) After completing this check, tighten the sensors all the way and check again using the same
I/O command.

When the conveyor height exceeds
950mm, shoes are placed over the casters.
In this case, the position of scale mark seal
(indicating the conveyor height) is also
raised by the amount of the shoe height.
