1.3 Remove the ANC unit
If the machine is equipped with an ANC unit (Option), remove it to create a work space.
1. Remove the chip damp box.
2. Remove the ANC unit
Remove the M6 screws (Qty:2) that secure the ANC unit.
Slide the ANC unit outward and sideways to detach it from the ANC unit base.
Note:
As the terminal connector that the signal wire and the air hoses are connected is attached to the ANC
unit, if you lift it up without detaching it from the ANC unit base, you may break the connector part.
Make sure to slide the terminal connecter to detach it from the ANC unit base and remove it.
* Although you can access to the screws that secure the ANC from above the ANC unit, there is
not enough space. Use a T-shaped wrench to remove the screws.

2. Change the board flow direction
2.1 Change the positions of the Transit position sensors
The positions of the Transit position sensors vary depending on the board flow direction.
Change the positions of the Transit position sensors and the brackets.
Figure 6
1. Remove the fiber sensor (Emitter).
As the positions of the sensor brackets need to be changed for changing the board flow direction,
remove the fiber sensor (Emitter).
Make sure to set the removed fiber sensor back to its original position.

2. Remove the sensor bracket.
Use the removed bracket for the opposite side lane.
Note:
When removing the bracket, be careful not to lose the plate nut that is behind the bracket to secure it
with the screws.

3. Move the fiber sensor (Receiver) position.
Remove the bracket and move the fiber sensor (Receiver) position.
The sensor position shown in the table below is the distance from the conveyor edge on the board
carry-in side.
Measure the distance from the conveyor edge and adjust the sensor position as follows.
<Board flow direction>
From Right to Left: Distance from the right side edge of the conveyor
From Left to Right: Distance from the left side edge of the conveyor
<Note for the work>
Adjust the sensor position by using a tape measure or a ruler.
When moving the sensor, DO NOT PULL the fiber wires. Cut off the cable ties that secure the
fiber wires as needed, and then bundle them again after adjusting the position.
Adjust the fiber sensor (Receiver) position so that it protrudes from the conveyor edge from
1mm to less than 3mm.
If the sensor protrudes 3mm or more from the conveyor edge, it may interfere with the
mounted component.
Caution:
As YSM40 is not equipped with the stoppers on the conveyor, it is possible to perform production even
though the sensor position is slightly shifted.
However if the position is significantly shifted, it may negatively affect the production speed and the
maximum board size that the mounting can be performed.
