Check
Does the problem disappear when the
power is switched OFF and then ON
again?
Does the problem disappear when circuit
breaker CB1 on the sorter controller PCB
is reset?
Set the meter to the 30VDC range; then,
connect the (+) lead to J2-1 and the (-)
lead to J2-3 of the sorter PCB. Is the volt-
age approx. 24V?
Is the fuse on the sorter power supply PCB
normal?
Set the meter to an AC range high enough
for measuring line voltage. Connect the
(+) lead to J106-1 and the (-) lead to J106-
2. Is the prescribed voltage supplied?
Set the meter to the x10k range. Is there
continuity between the sorter controller
PCB and the DC controller PCB?
Does the problem disappear when the DC
controller PCB or the sorter controller
PCB is replaced?

CHAPTER 10 TROUBLESHOOTING
Result
Yes End. (Check the wiring
between the DC control-
ler PCB and the sorter
controller PCB.)
Yes End. (Be sure to deter-
mined the reason why
CB1 tripped.)
Yes Check from step 6
No Replace the fuse
Yes Replace the sorter power
supply PCB.
No Check the wiring be-
tween the sorter power
supply PCB and the AC
driver PCB.
Yes Check if the cable be-
tween the sorter control-
ler PCB and the DC con-
troller PCB is connected
correctly. If it is normal,
replace the sorter con-
troller PCB.
No Replace the communica-
tions cable.
Yes End.
