The PCB detection
sensor on the
upstream process
conveyor does not
detect the PCB.
Check the sensor for contamination.
If contaminated wipe it off.
Two PCBs are
loaded.
Check the PCB unloading signal
(BA signal) of the upstream
process. Adjust as necessary.
1.Check the alignment of the
conveyor coupling to the
upstream process. If necessary,
adjust the alignment.
2.Check the belt or the guide.
If it is contaminated, wipe it off.
The PCB stays on
the conveyor.
The PCB stays on
the entrance of the
upstream process.
PCB transfer error
A belt or a guide is
contaminated.
Clean the belt or the guide.
The PCB detection
sensor on the
conveyor detects
the PCB although it
does not exist.
Check the sensor for
contamination. If contaminated
wipe it off.
PCB loading error
The PCB request
signal of the
downstream
process does not
turn OFF within
the PCB unloading
waiting time
Check the PCB request signal
(READY signal) of the downstream
Process output.
Check the PCB unloading waiting
time. Adjust if necessary.

Check the slit size of the PCB.
(Use within the limit of the notch
allowable dimension.)
1.Check the alignment of the
conveyor coupling to the
downstream process. If
necessary, adjust it.
2.Check the belt or the guide. If it is
contaminated, wipe it off.
Check the length of the placed
component extending off the
