Series Banknote Validator (DBV-400) Integration Guide
The External LED Display indicates various com-
binations of solid or alternating Color light flashing
conditions when any of the Standard Error and
Reject Codes listed in Table 22 and Table 23 occur.
Identify the cause and solution for an indicated
error by comparing it against each listing in Table
22. Ensure that the relative Assemblies are properly
connected and/or harnessed, and all of the Unit’s
sensors are clean before proceeding to troubleshoot
the error condition.
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 performing the Performance Test. The
LED shows more detailed flash patterns while
running the Performance test to identify the
specific error causes
