Introduction
Most Banknote Validator failures result from minor
causes. Before replacing any parts, be sure that all
assembly and circuit board connectors are properly
fitted with their harnesses properly connected.
Poor performance by the DBV-400 Banknote Vali-
dator is often caused when dust or foreign objects
adhere to the sensors or rollers. Clean the Banknote
validation section first, then carefully observe the
operating state of the Validator when re-initializing
power. This observation is important in locating
any causes of failure and the possible fault
location.
Perform all repairs by referring to Calibration and
Testing in Section 6 of this Manual, and the Disas-
sembly/Reassembly instructions in Section 4 of
this Manual.
Troubleshooting Overview
This product allows the operator to perform fault
diagnosis by checking various Fault Table Listings
against the symptoms. Survey the cause(s) of any
failure occurrences during the process.
After determining the cause of the failure, execute
the Performance Test, and then repair the unit,
replacing any appropriate parts deemed necessary.
