CHAPTER 10 TROUBLESHOOTING
Description
A machine internal communication
error occurs more than once. Or, the
reception interruption on the DC con-
troller side does not occur for a spe-
cific time for internal communication.
The IC on the DC controller PCB has
an error.
• The DPPRDY signal is not sent for
0.25 sec or more from the reader
controller to the DC controller PCB
after the DC controller PCB is sup-
plied with power.
• The signals between the PS/PCL
board and the DC controller PCB or
between the PS/PCL board and the
reader controller PCB cannot be
exchanged for a specific time after
the PS/PCL board is supplied with
power.
The bin flapper solenoid sensor
(PI12) does not detect solenoid oper-
ation even when the solenoid (SL3) is
driven during initialization or face-
down delivery. Or, the bin flapper sen-
sor remains on even when the sole-
noid has stopped operation.

ation even when the solenoid (SL4) is

sor remains on even when the sole-

• The ACC controller PCB and the
accessory fail to become ready for
communication in 4 sec (possibly, a
problem in the power supply).
• An initial communication error with
each accessory has occurred.
• The accessory is turned off in the
middle of communication.
• The cable of the accessory has
been disconnected in the meddle of
communication.
The read/write/parity check of data is
faulty, and communication fails to end
within a specific time.
