behind the acceptor, is a single switch module
containing three rocker switches. When the top
of the rocker switch is pushed in it is the ON
position. The switches correspond as follows:
Section 2: Installation
1=USA/CAN Not Used
2=LO 2 ¢ ON: Quarters are directed to cash
box once change tube has
approximately 28 quarters
OFF: Quarters are put into change
tube until it is full.
3=$ACPT ON: Dollar coin will be accepted
OFF: Dollar coin will be rejected
3. Set option switches to desired setting.
4. Return acceptor to operating position making
sure acceptor latches secure acceptor.
. Test with a variety of coins to ensure proper
operation.
Figure 2

Page 6
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 7
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 8
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.
VEND
Vend is a function of the vendor electronic
controller. The vendor controller accumulates all
credit information received from the coin changer.
As credit is accumulated in the vendor controller,
vend selections can be made when their respective
vend price settings are equalled.
COIN PAYOUT
Coins are paid out from the coin changer when a
change payback is required or when either of the
coin changer inventory switches are manually
operated. Coins are dispensed by D.C. solenoid-
operated slides located at the bottom of each of the
three coin tubes. The payout solenoids are controlled
by signals generated by the vendor controller or the
three inventory switches.
When a solenoid energizes, the upward motion of its
plunger compresses a spring and draws the solenoid
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. Coin
payout rate is determined by the vendor electronic
controller board.
Inventory Switches
Located on the front of the coin changer is a nickel,
dime and quarter inventory switch. These switches
are used to manually remove coins from the changer
coin tubes. They are disable while the vendor is in a
vend cycle.
Section 3: Operation
Figure 7
Figure 8

Page 9
Section 3: Operation
CHANGE STORAGE
See Figure 8
The full tube sensors in each coin tube continually
report the (full/not full) status to the coin changer
logic board. 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 t e quarter tube is full (full
sensor blocked by coins) t e acceptor coin tube
gate will remain closed and t e cas box gate will
open eac time a quarter is accepted, routing all
quarters to t e vendor cas box via t e c anger
coin c ute.
After one or more quarters are paid out as change,
leaving the full sensor exposed (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. NOTE: If the changer (LO-
$.2 ) option switch is set to the ON position,
accepted quarters will be routed to the cash box
when the (middle $.2 tube sensor) is blocked by
coins.
The low tube sensors in each coin tube continually
report the (blocked/not blocked) coin level status to
the vendor controller. This information is used to
determine if change is available for payout.
CORRECT CHANGE OPERATION
The coin changer continually reports the status of the
low tube sensors to the vendor's controller. The
logic control for correct change is initiated by the
vendor controller.
ESCROW RETURN
Escrow return is a function of the vendor
electronic controller. Coins are always accepted
regardless of the coin tube levels.
The value of each coin is accumulated in the
vendor controller. If a coin return is requested, a
signal is sent to the appropriate payout solenoid(s) to
pay back coins of the same denomination. If a dollar
coin has been accepted, change will be returned in
the least number of coins possible if an escrow
return is requested.
INTERFACE BETWEEN THE
9302-GX COIN CHANGER AND
VENDOR / CONTROLLER
See Figures 9 and 10
The 9302-GX changers interface connector is
shown in Figure 9. Figure 10 shows the interface

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 Tu e and Sensor Assem ly
Remove the logic board cover by inserting a straight
tip screwdriver in the slot above the tube assembly.
Twist the screwdriver to release the ccover.
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 Assem ly
Unplug payout solenoids, and main harness assembly
from logic board. Lift logic board out of housing.
Section 4: Maintenance
Payout Assem ly
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 9302-GX 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 11.

Page 12
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
SOLENOIDS IN WATER.
Replace slides making sure part numbers face up
into changer. With the slides correctly seated on
plunger tabs, reinstall the bottom plate, securing with
bottom screws. 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.
Access holes are also provided at the rear of the
changer housing to help relieve coin jam.
CAUTION: Excessive screwdriver pressure or
twisting can cause permanent damage to t e coin
c anger.

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: T e following Troubles ooting Guide is
based on t e fact t at t e tester or vendor, wit
