3. Refer to the following table to match up the sensor numbers shown in the above
diagrams with the official sensor name, signal name and I/O channel.
4. The following table shows the I/O channel in relation to the wiring code and line
number for each sensor. The wiring codes are displayed on the conveyor and the line
numbers can be found where the sensor wires connect to the conveyor control board.
Refer to the photographs on the following page for further reference.

5. To check the operation of each sensor, block the beam and check that the status of
the I/O changes accordingly. Note that there is a short delay between blocking the
sensor on the conveyor and the change of status in the I/O check display.
6. Confirm that when the sensor sensitivity adjustment output (CY004 and CY009) is ON
the amplifier displays “PH”. This sensitivity adjustment should be carried out whenever
the conveyor width is changed. To carry out the adjustment turn CY004 and/or CY009
ON and then OFF.
7. Use the list boxes on the output side of the I/O check window to turn each address ON
and OFF. Confirm that the corresponding actuators (etc) function normally.
8. Check that when the conveyor panel pass check L sensor (CX000 & CX008) comes
ON, the adjacent module stop trigger (CX002 & CX00A) for the same lane comes ON
simultaneously.
9. Turn ON the CY002 output and confirm that the green LED (front adjacent module stop
trigger) on the CID illuminates.
10. Turn ON the CY007 output and confirm that the red LED (rear adjacent module stop
trigger) on the CID illuminates.
11. Use the CY000 and CY001 outputs to clamp and unclamp the front conveyor and
check that the CX004 input turns ON and OFF.
12. Use the CY005 and CY006 outputs to clamp and unclamp the rear conveyor and
check that the CX00C input turns ON and OFF.
When CY004 &
CY009 are ON
the amplifiers
should display
“PH”
