"bottler"interface,which communicates to the vendor
through either HIGH LEVEL or MDB communication.
BA30SA and BA32SA bill acceptors are primarily used
in either electronic or MDB snack, coffee or food ma-
chines. These bill acceptors use the "snack" interface and
communicate to the vendor through either PULSE,
SERIAL, PARALLEL or MDB communication.

shippingcompany immediately. Onlytheco-signee (the
person or company receiving the unit) can file a claim
against the carrier for shipping damage. We recommend
that you retain the original carton and packing materials
to reuse if you need to transport or ship your acceptor in
the future.
If the bill acceptor is being stored or used as a spare,
always keep it in its shipping carton when not in use.
This will keep it clean and offer the best protection for
the unit.

SECTION 1: GENERAL INFORMATION
MAIN LOGIC BOARD ASSEMBLY
The main logic board contains the microprocessor which
controls all the functions of the bill acceptor based on
informationfromthevendingmachine,coinmechanism
and various bill acceptor sensors.
Also contained on the main logic board is the power
supply which receives its primary voltage from the
vending machine. For 117VAC units, the primary AC
voltage is routed to the transformer in the bill acceptor
where it is reduced to 24VAC. This 24VAC is then
routed back to the main logic board where it is rectified
and filtered for logic board operation. For 24VAC and 24
VDC (MDB) units, no transformer is needed. The
primary voltage is rectified and filtered on the main logic
board.

BILL RECOGNITION
When a bill is inserted into the bill acceptor and it blocks
the left and right alignment sensors as well as the center
optic sensor, the transport motor beings to run.
BILL VALIDATION
From the time the transport motor begins to run until the
trailing edge of the bill leaves the alignment sensors,
optical and magnetic sensors send information to the
microprocessor to determine the validity of the bill.
BILL STACKING AND CREDIT
If the bill is determined to be authentic, it is transported
to the stack position. Once the sensors of the lower
housing’santi-pullbacklever signals the microprocessor
that the bill is in the stacking position, the stacker motor
runs and credit is given.
BILL REJECTION
If the bill is determined to be invalid, the wrong denomi-
nation or the anti-pullback levers are active when the bill
is determined to be in the stack position, the transport
motor will reverse returning the bill to the customer.
COMPONENT EXPLANATION
( ee Figure 3)
Bill Tran port and Stacking
The bill transport system is composed of a motor and
gearcase assembly and three sets of pulleys and belts: the
lower housing belts, the chassis belts and the intermediate
frame belts. When the transport motor is energized, it
pulls the bill in by sandwiching it between the lower
housing belts and the chassis belts. During the validation
process, the bill is transferred from the lower housing and
chassis belts to the intermediate frame and chassis belts.
The bill stacker is composed of a motor and gearcase
assembly and a pusher plate assembly. When the bill is
transported past the anti-pullback levers into the stacking
position, the stacker motor energizes driving the pusher
plate, which in turn, pushes the bill into the bill box.
Left and Right Alignment Sen or
The left and right alignment sensors send information to
the microprocessor to insure that the bill is the right
width and that it is being fed in correctly.
Center Optic Sen or
The center optic sensor informs the microprocessor that
the bill is ready to be transported if the information from
the alignment sensors is correct.
Left and Right Optic Sen or
The left and right optic sensors and associated circuitry
perform various optical checks on the bill and send that
information to the microprocessor for bill validation.
Magnetic Sen or
The magnetic sensor and its associated circuitry performs
checks on the magnetic properties of the bill and sends
that information to the microprocessor for bill validation.
Anti-Pullback Lever
The lower anti-pullback lever is optically monitored to
tell the microprocessor when the bill has entered the stack
position or if an attempt to defraud the unit is taking
place.
Stacker Home Sen or
The stacker home sensor is an optical sensor that informs
the microprocessor of the position of the stacker pusher
plate.
Encoder Sen or
Connected to the transport motor is an encoder wheel
which is optically monitored to determine the speed of the
transport motor and to determine the position of the bill
in the bill path.
Bill Box Switch
The bill box switch (if installed) resets the bill acceptor
each time the lid is closed. For units without a bill box
switch, reset is microprocessor controlled.

BA30 CLEANING MAINTENANCE
PROCEDURE
NOTE: Petroleum-based cleaners and freon-based
propellants can damage plastic and some electronic
components. Scouring pads and stiff brushes may harm
the protective coating on the circuit boards and can mar
the plastic. These items should never be used when
cleaning the BA30 bill acceptor.
The BA30 should be cleaned every 20,000 bills or every
two years (or as needed, depending on the environmental
conditions of the location). Dust can be removed with a
soft brush or cloth or it can be blown out using com-
pressed air.
Procedure
1. Disconnect power from the bill acceptor.
2. Remove the bill box and use a soft cloth to wipe any
dust from around the intermediate frame and stacker
plate.
3. Removethelowerhousing.
4. Using compressed air or a soft brush, blow or brush
the dust off of the optic sensors and out of the
recessedsensoropenings.
5. Remove dust from around the belts and pulleys on
the lower housing and the sensors on the upper
sensor board. The upper sensors are located directly
above the lower housing sensors when the lower
housingis installed.
6. The bill path can be further cleaned of any dirt or oil
by using a soft cloth moistened with a mild soap and
watersolution.
7. Clean the magnetic head with a cotton swab and
isopropylalcohol.
8. Blow the dust out of the encoder wheel and its
sensor. (It may be necessary to extend the stacker
plate to access the encoder wheel. This can be done
by supplying power to the unit momentarily so the
stacker plate extends outward.)
9. Remove dust from the transport belt areas and any
other places of build up.
10. Once the lower housing is dry, place it back into the
mainframe making sure the tab on the bottom locks
into place.
11. Remount the bill box.
12. Apply power and insert bills to verify the unit is
functioningproperly.

orloose/faulty connections.Pleasecheck thefollowing
before replacing any parts:
• Clean any dirt or dust from the bill path.
• Coin changer inventory tubes are filled to their
correctlevels.
• 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
smokedgraycover.
For all BA30s up to serial number 1297XXXXX
with CPU 92106 -5 or 92163 - :
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 BA30s 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.
