Appendix A
The Bezel LED and Status LED indicate various
combinations of solid or alternating Color light
flashing conditions when any of the Standard Error
and Reject Codes listed in Table A-4 and Table A-5
occur.
Identify the cause and solution for an indicated
error by comparing it against each listing in Table
Table A-3

Possible Fault Causes
Corrective Action Required
Cannot
communicate with the
Host Machine
DIP Switch settings are
incorrect.
Set all DIP Switches to OFF, and then set DIP Switches correctly while
referring to the “Software Information Sheet.”
Connectors are disconnected
or loosely connected.
Firmly re-seat all of the Communication Connectors.
Damaged Connector Pins
Check for any bent, missing or damaged Pins in the Connector Plugs and
mating Receptacles.
CPU Board is corrupted
Exchange the CPU Circuit Board with a known good Circuit Board.
Incorrect Interface
Verify that the correct interface between the Host Machine and the Banknote
Validator is being used.
Communication Error
Table A-3 lists the various possible DBV-400 Unit Communication fault conditions.
LED Indication Conditions
NOTE: Error Codes and Reject Codes flash
different patterns when in the Normal
Operation mode (communicating with the
Host Machine) or when running the
Performance Tests. The LED shows more
detailed flash patterns while running the
Performance Tests to identify the specific
error causes.
