SECTION 5: TROUBLESHOOTING
INTRODUCTION
The Troubleshooting Guide on the following pages is
intended to help locate problems within the bill acceptor.
If a bill acceptor cannot be repaired by following this
guide, return the unit to the nearest Coinco Service
Center for repair along with a complete description of the
problem you are having with the bill acceptor.
Logic troubleshooting minimizes the time spent in
removing and replacing parts that are not defective.
Some failures are caused by minor problems such as dirt
or loose/faulty connections. Please check the following
before replacing any parts:
• Clean any dirt or dust from the bill path.
• Coin changer inventory tubes are filled to their
correct levels.
• Connectors are inserted correctly.
• Connector pins are not bent or broken.
• All wires are properly secured.
COINCO BA30 DIAGNOSTIC CODES
Troubleshooting can be done by reading the number of
flashes or blinks of light from the LED located inside the
logic board cover. These flashes can be seen through the
smoked gray cover.
For all BA30s up to serial number 1297XXXXX
with CPU 921068-5 or 921638-8:
Diagnostic codes 1-5 may appear during normal servic-
ing of the BA30. To access diagnostic codes 6-18, open
the bill box lid and turn off power to the BA30 for 10
seconds. Reapply power to the BA30 with the bill box
lid open. Diagnostic codes 6-18 will appear for the
respective error conditions detected in the BA30. If more
than one error exists, the lower number code will appear
until its condition is corrected.
For BA30s manufactured after serial number
1297XXXXX with CPU 67044-4:
Diagnostic codes 2, 8, 14, and 18 are not used. Codes 1,
3, 4, 5, 15, 16 may appear during normal servicing of the
BA30. If the BA30 is flashing a #5 code, turn off power
to the BA30 for 10 seconds. Reapply power to the BA30
and diagnostic codes 6, 7, 9, 10, 11, 12, 13, and 17 will
appear for approximately 30 seconds. After 30 seconds
these codes will revert back to the #5 code. If more than
one error exists, the lower number code will appear until
its condition is corrected. The left and right sensors
referenced in the next column are given viewing the
BA30 from the front.
* Units beginning with serial #109300187 do not have a
bill position sensor.
* Units beginning with serial #359300001 do not have
upper board anti-pullback sensors.
** Bill box diagnostic code is used on BA30B models
with the CPU #921068-5 only.
