2.2 Change the wiring
2.2.1 Change the location of the Entrance and Exit sensors and connector pins
(Tentative measure)
As interchanging the harnesses of the Exit/Entrance sensor requires a lot of man-hours, change
the pin configuration of the connector (CN22) connected to the I/O conveyor board.
Note:
The procedure described in this section (changing the position of the connector pins) is used
temporarily.
A relay harness is planned to be added as a permanent measure. (Under review)
The work described in this document is NOT normally performed. When you need to change the board
flow direction, please make sure to contact YAMAHA.
Figure 12
1. Remove the slope on the rear side of the tape cutter unit.
If the slope is not removed, remove it referring to “1.2 Remove the slope”.
2. Remove the base cover.
Remove the base cover on the back side, on the left side of YSM40.
The I/O board is behind the cover.
3. Remove the CN22 connector and change the pin configuration.
The connector second from the upper left of the I/O board is CN22.
Check the mark tube and disconnect the connector and change the location of the ENTRANCE
and the EXIT pins referring to the figure below.
Figure 13
Warning:
The procedure mentioned above is only a tentative measure.
Make sure to attach a label on the altered sensor so that other people can easily tell that the pin
configuration of the connector has been changed when they perform maintenance.
Also, make sure to release a report to YAMAHA to inform that you have changed the board flow
direction.

2.2.2 Interchange the signal wires (NEXT, PREVIOUS)
In accordance with the change of the board flow direction, the connecting location of the signal
wire (NEXT, PREVIOUS) is supposed to be changed.
However, it requires a lot of man-hours for routing the wires and exchanging the connectors.
Although the wires cross each other, it does not affect the production. Route the signal wires
(NEXT, PREVIOUS) under the base.
Make sure to prepare 5m or longer signal wires (NEXT, PREVIOUS).

Table 2
Discuss with the customer about the work previously, and if the signal wires need to be routed, you
need to route the wires, change the connectors and detach/attach the covers.
Note:
Make sure to route the wires so that they do not interfere with the Feeder exchange carriage/C-ATS
when removing/setting the unit.
Figure 14
Route the signal wire via the adjusting bolts (outer side) so that it
does not interfere with the Feeder exchange carriage/ C-ATS
when removing /setting the unit.
It is recommended to secure the wires at two (2) positions with
cable ties so that they do not sag.
Make sure to set the mount base 10mm inward from the
H-shaped pitted area on the base of YSM40 (Viewed
from underneath) to avoid the interference.

2.3 Adjust the optical axis of the sensor
1. Power ON the machine.
Power ON the machine in order to adjust the positions of the sensor and the optical axis.
Warning:
DO NOT START SUPPLYING AIR until the tape cutter slope is set to the unit.
If the tape cutter accidentally starts, it is very dangerous.
2. Adjust the optical axis of the sensor.
Adjust the emitter side optical axis position so that it is located in the center of the receiver side
sensor (whose position has been adjusted) by shifting the emitter side sensor.
Position the optical axis so that it is located in the center of the receiver head while checking the
value of the amplifier.
Figure 15
3. Check the address of the sensor position.
Make sure that the I/O address of the sensor is the same as the address of the fiber interchanged
in “2.1 Change the positions of the Transit position sensor, step 5”.
The Transit position sensor of YSM40 is usually in the OFF-state.
1) Click the [Sensor Light] button on the [Unit]-[Conveyor] window to make the sensor react.
2) Select “Conveyor” from the pull-down menu of “Input” on the [Unit]-[I/O] window.
3) Put your hand above the sensor to check if the sensor reacts at the address from N230000
through N230100. If it is detected, “DETECT 1” is displayed, if it is not detected, “NOT
DETECT 0” is displayed.
If the sensor reacts at the different position on the I/O window, the fiber position at the
amplifier is not appropriate.
Change the fiber position referring to “2.1 Change the positions of the Transit position
sensor”, step 6.
If the amplifier reacts but the I/O does not, the optical axis position may not be
appropriate.
Check the position by shifting the emitter side sensor from side to side. If the I/O still does
not react, move the sensor up and down.
Sensor (Receiver)
Make sure that the protrusion of
the sensor form the conveyor
edge should be 3mm or less.
Adjust the optical axis position so that
it is located in the center of the
receiver head while checking the
value of the amplifier.
