MAIN LOGIC BOARD ASSEMBLY
The main logic board contains the microprocessor
which controls all the functions of the coin changer
based on information from other changer parts as
well as the vending machine.
Also contained on the main logic board is the power
supply which receives the primary AC voltage from
the vendor. From there the primary AC voltage goes
two places to be rectified to a DC primary voltage
to operate the coin dispensing solenoids, and to the
changer transformer where it is stepped down to a
12 VAC voltage. This 12 VAC is routed back to the
control board where it is rectified and filtered for
logic board operation.

COIN RECOGNITION
See Figure 3
As a coin enters the changer through the acceptor
funnel, its impact is absorbed by a white ceramic rail
which debounces the coin and allows it to continue
down the coin rail at a smooth and steady speed. As
a coin rolls down the rail, it passes between two sets
of LED sensors which measure the speed and size
of the coin. The coin also passes between two sets
of coils which measure the metallic content of the
coin. These measurements are used to determine if
the coin is valid and the value (denomination) of the
coin.
COIN SEPARATION
See Figure 3
After the coin's validity has been determined the coin
rolls off the end of the coin rail and enters the
separator section of the acceptor. The UPPER
(coin tube) gate and the LOWER (cash box) gate
are opened and closed by their respective solenoids.
These solenoids are energized and de-energized by
an electrical signal from the acceptor logic board
based on the following criteria
 the validity of the coin.
 the denomination of the coin.
 the status (full or empty) of the appropriate coin
tube.
The positions of these two gates cause the coin to be
routed to one of three places the appropriate
changer coin tube, the vendor cash box, or if the coin
is rejected, the vendor coin return cup.
REJECTED COIN
See Figure 4
If a coin is rejected for any reason, both the UPPER
(coin tube) and the LOWER (cash box) gate will
remain closed. All rejected coins will drop into the
vendor return cup via the coin changer coin return
chute.
Section 3: Operation
Figure 3 Figure 4

Page 8
ACCEPTED COIN
See Figures 5 and 6
An accepted coin will be routed to either the vendor
cash box or to one of the changer coin tubes. The
(FULL) sensors in each coin tube determine which
route the coin will take. If the coin tube
corresponding to the validated coin is full (full sensor
covered by coins in change tube), the cash box gate
will open, allowing the coin to drop into the vendor
Section 3: Operation
cash box via the changer cash box chute. If the
appropriate coin tube is not full (full sensor not
covered by coins), the coin tube gate will open
directing the coin down a ramp. Along the wall of
the ramp are windows for entry into the coin tube.
As the coin reaches a window of the appropriate
size, it falls into the coin tube. All dollar coins are
always directed to the cash box via the cash box
chute.
Figure 5 Figure 6

Page 9
CREDIT AND ACCUMULATION
See Figure 7
There are two sensors, one in the separation section
of the acceptor and one in the cash box path of the
acceptor. As coins pass either one of these sensors,
the changer sends credit information to the vendor
electronic controller where the coin credit is
accumulated.
MAIN LOGIC BOARD
The main logic board is responsible for all logic
functions of the changer. It receives information
from other changer modules as well as the vending
machine, and based on this information, controls the
operation of the changer.
The main logic board also contains the changer
power supply. It receives the incoming AC voltage
from the vendor and does the following First, it is
rectified to a DC voltage for the payout solenoids.
Second, it is routed to the transformers primary
where it is reduced to 12 VAC. This 12 VAC is
routed back to the logic board where it is rectified
and filtered to the operating DC voltage.
COIN TUBE SENSING
See figure 8
The low tube sensors in each coin tube continually
report the (blocked/not blocked) coin level to the
microprocessor. This information is used to
determine the availability of change for change
payback, escrow and exact change condition.
The full tube sensors in each coin tube continually
report the (full/not full) status to the coin changers
microprocessor. The information is then used to
determine the placement of the next accepted coin.
This information controls the action of the acceptor
coin tube and cash box gates.
EXAMPLE If the quarter coin tube is full (full
sensors blocked by coins) the acceptor coin tube
gate will remain closed and the cash box gate will
open each time a quarter is accepted, routing all
quarters to the vendor cash box via the changer coin
chute. After one or more quarters is paid out as
change, leaving the full sensor exposed (quarter tube
not full), the acceptor coin tube gate will open each
time a quarter is accepted, routing quarters to the
changer coin tube until it is full again.
Section 3: Operation
Figure 7
Figure 8

Page 10
Section 3: Operation
NOTE If the changer LO-$.25 option switch is set
to the on position, accepted quarters will be routed to
the cash box when the (middle $.25 tube sensor) is
blocked by coins.
CHANGE PAYBACK
The low tube sensors report which coins are
available for payback so payout can be made in the
fewest coins available.
EXACT CHANGE CONDITION
The microprocessor is constantly looking at the
change status. If correct change cannot be made,
the changer rejects the last coin deposited, resulting
in an over insertion. At this time, the correct change
light flashes on and off in one second intervals for 10
seconds, during which time the escrow lever may be
depressed for a full refund, the correct change my be
inserted or the same coin which was rejected may be
reinserted. (However, no change payout will be
attenped under this condition.) If correct change
cannot be made for a dollar bill, the correct change
light will be lit continuously, inhibiting the bill
validator.
COIN PAYOUT
The payout assembly pays out coins using three
solenoid-operated slides. Coins are paid out for
change payout, escrow return and manual inventory
of the coin tubes.
When a solenoid energizes, the upward motion of its
plunger compresses a spring and draws the soenoid
lever, which in turn pushes a payout slide forward.
This loads the coin for payout. When the solenoid
de-energizes, the spring force returns the plunger to
its de-energized state, which returns the solenoid
lever and payout slide, dispensing a coin. Payout
rate is two coins per second.
Change Payout When the amount of credit exceeds
the vend price, a payout will be made in the least
number of available coins. (See Exact Change
Condition.)
Escrow Return When a request for escrow is
made, the changer will return the amount credited in
the least number of coins. Under exact change
conditions, nickles, dimes and quarters may be
returned coin for coin.
Manual Inventory of Coins Operating the manual
inventory switches manually empties the changer
coin tubes. The inventory switches are located on
the front of the inventory tube assembly. Only one
inventory switch will operate at a time.
DOLLAR CREDIT ESCROW
Credit from the dollar bill validator or dollar coin is
not inhibited from escrow. Four quarters will be
returned to the customer if an escrow is called for.
ESCROW
Escrow Until Vend Allows the customer to get a
full refund any time before actual vend price is
reached.
Escrow Until Select Allows the customer to receive
a full refund any time prior to product delivery.
NOTE: Then vendor circuit determines whether the
escrow to select feature can be used.

ESCROW UNTIL VEND CHANGER
VENDOR INTERFACE
See figure 9 and 10
As coins are inserted, the changers logic board
compares the accumulated credit to the vend price.
When adequate credit is reached, the changers
logic board activiates the changers vend relay for
250 milliseconds. This energizes the vendors credit
relay, cancels the changers credit and initiates the
change making cycle if required.
The energizing and latching of the credit relay
removes power from Jones plug line six, which
inhibits the acceptance of coins and enables the
selection switches for vending. The changers vend
relays N/C contact connects the AC hot line to the
vendors credit relays N/O contact.
When a selection switch is activated, the vendors
vend motor begins to run. The vend motor
mechanically activiates a motor carrier switch which
holds power to the vend motor until the motor returns
to its home position and deactivates the vend relay of
the vendor. This returns power to Jones plug line six
enabling the acceptance of coins.

ESCROW UNTIL SELECT
CHANGER VENDOR INTERFACE
See figure 11
As coins are inserted, the changer microprocessor
accumulates and holds the credit until a selection and
delivery are made. When a selection is made, the
changer senses the selection through Jones plug line
three. If the accumulated credit is equal to or
greater than the vend price, the chager will send a
hot AC signal out on Jones plug line three, until the
hot AC signal to Jones plug line six is borken. At this
time, the changer will pay out any change owed and
reset. Upon the return of the hot AC signal to Jones
plug line six, the changer will stand by for the next
transaction.
If an escrow is detected while waiting for the hot
AC signal to Jones plug line six to break, then the hot
AC singal to Jones plug line six is monitored for two
seconds. If the hot AC singal to Jones plug line six
does not break in this two seconds, then an escrow
of the accumulated credit is made. If the hot AC
signal to Jones plug line six does break within two
seconds, then the escrow is ignored and the changer
pays out any change owed and resets. Upon the
return of the hot AC signal to Jones plug line six, the
changer will stand by for the next transaction.

ROUTINE MAINTENANCE
Routine maintenance will improve performance and
extend the working life of the 9300 series changer
and reduce the need for more involved repairs.
Frequency of routine maintenance will depend on
environment and number of transactions.
The coin changer should be kept in its original
shipping carton when not in use. This will keep the
changer clean and provide the best protection for the
unit.
REMOVING/REPLACING
INDIVIDUAL MODULE
ASSEMBLIES
Modular assembly replacement provides the basis of
all 9300 series changer repair. Instructions for
removing and replacing modules are provided below.
These modules should be removed in the following
sequence
Acceptor
To remove the acceptor, raise the two acceptor
latches and pull the top of acceptor forward and
away from the changer housing. Unplug acceptor
ribbon cable from main logic board. Raise acceptor
and pull outward until the acceptor clears the housing
slots.
Coin Tube and Sensor Assembly
Remove the logic board cover by inserting a straight
tip screwdriver in the slot above the tube assembly.
Twist the screwdriver to release the cover.
Unplug tube sensor ribbon cable from logic board.
Spread the lower part of the housing slightly and
pullout on tube assembly. To separate the coin tube
assembly from the tube sensor board assembly, place
the assembly face down. While freeing the four
locking tabs, pull up on tube sensor board. Be
careful not to damage sensors on logic board.
Main Logic Board Assembly
Unplug payout solenoids, and main harness assembly
from logic board. Lift logic board out of housing.
Section 4: Maintenance
Payout Assembly
With payout solenoids disconnected from main logic
board, remove the four screws - two from each side-
at the bottom of the housing. Separate payout
assembly from changer housing by releasing cash
box chute locking tab on back of changer housing
and pulling downward on payout assembly.
CLEANING
Your 9300 series changer is made of a high-quality
industrial grade plastic which should only be cleaned
with a warm water and mild detergent solution.
CAUTION:
 Never submerge c anger in water.
 Do not use petroleum solvents, steel wool,
scouring pads, or a metal brus for
cleaning.
 Do not spray any part of c anger wit
any type of lubricant.
Since all coins share a common coin ramp, heavy
usage or a dirty environment can result in dirt build
up. To clean the coin ramp, lift the acceptor gate
upward and diagonally to the right. Hold gate firmly
to prevent it from snapping back. Wipe the exposed
coin ramp and inner surface with a damp cloth. For
excessively dirty units, use a damp cloth with a mild
detergent. NOTE: Do not submerge in water.
For detailed cleaning of the acceptor, remove the
front cover by pulling out and down of the front
cover. Now remove the back cover by pushing in on
two locking tabs on the side of the acceptor. To
remove the coin sorting rail, snap the coin sense coils
from the sorting rail and the cash box exit, being
careful not to break coil wires. Free coil wires from
the clip on the sorting rail. Now from the front of the
acceptor, in area exposed by removing the front
cover, locate the three locking tabs which secure the
sorting rail. Using a small straight tip screwdriver,
free the three locking tabs and remove sorting rail.
See Figure 12.

Page 14
DISASSEMBLING PAYOUT BASE
FOR CLEANING
Remove the four Phillips head screws from the
bottom plate. Remove bottom plate and individual
slides. Clean parts with mild detergent and hot water
as desired.
DO NOT SUBMERGE TRANSFORMER OR
SOLENOIDS IN WATER.
Replace slides making sure part numbers face up
into changer. With the slides correctly seated on
plunger tabs, reinstall the transformer and bottom
plate, securing with bottom screws. The
transformers black wires must be to the right (away
from) the solenoids. Reinstall payout module into
changer, securing with side screws.
CLEARING COIN JAMS
Should a coin jam occur in the cash box chute area,
use the following steps to help dislodge coins
1. Remove changer from vendor.
2. Keeping changer in an upright position, insert a
narrow screwdriver into cash box chute or reject
chute from bottom of changer to relieve jam.
CAUTION: Excessive screwdriver pressure or
twisting can cause permanent damage to t e coin
c anger.
