INTRODUCTION
The Troubleshooting Guide on the following pages is
intended to help locate problems within the coin
changer. If a changer cannot be repaired by
following the guide, return the changer to the nearest
Coinco Service Center for repair. If it is necessary
to return the changer to Coinco, please accompany
the changer with a brief description of the
malfunction to help expedite the repair and return of
the changer.
The vendor electronic controller board is in constant
communication with the 9302-GX coin changer. The
electronic controller board not only supplies operating
voltage to the coin changer but is largely responsible
for the operation and function of the coin changer.
(Refer to Section 3, Figure 10)
Logic troubleshooting minimizes time spent in
removing and replacing modules that are not
defective. Some failures are caused by minor
problems such as loose or faulty connections. Please
check the following before replacing any parts:
Connectors are inserted correctly.
Connector pins are not bent or broken.
All wires are properly secured.
Inventory tubes are filled to their correct levels.
NOTE
: The following Troubleshooting Guide is
based on the fact that the tester or vendor, with
which the defective changer is being tested,
functions properly when used with a known good
changer.
This guide is not intended to cover all failures, but to
cover the most common failures.
