Section 2 – Setup & Installation
2.2 – Mounting Instructions
This machine must be installed in accordance with local codes. If you are unsure in any way what your
local codes are or unsure of anything in the following steps, please hire a licensed professional to
mount your machine.
1. Disconnect any and all AC power going to the machine. (Unplug AC line cord from the rear of the
machine.)
2. Note: You will need to verify with the building code enforcement to see if it is allowable to plug the
changer into a grounded outlet. If it is not, there must be 120VAC run through conduit or other
means to meet local codes to the changer. If it is not required, proceed to step #6.
3. Have a licensed electrician run the conduit, install the new breaker, wire and help decide how the
wiring will enter the changer (from the back or the bottom).
4. After the conduit has been installed, proceed with securing the machine to a stable structure.
5. Find an appropriate stable structure which to secure the machine to.
6. NOTICE: BEFORE SECURING ENSURE THE MACHINE IS LEVEL.
7. : PROPERLY SECURE MACHINE (PRODUCT) TO THE FLOOR SO THE MACHINE
(PRODUCT) CANNOT BE MOVED OR TIPPED. USE STRUCTURAL SOUND FASTENERS THAT CAN BE
PROPERLY TIGHTENED AND SECURE THE MACHINE (PRODUCT) THROUGH EACH OF THE HOLES IN
THE BASE OF THE MACHINE (PRODUCT) TO THE APPLICABLE SURFACE TO WHICH IT IS BEING
SECURED.
8. Use the four holes located in the back, bottom, or sides of the cabinet to secure the machine to a
stable structure.
9. Verify that the machine is properly secured to the stable structure.
10. Connect your AC line to the outlet. If conduit was run wire it to the power supply located in the
machine.
a. Do not use an extension cord unless allowed by the building electrical code.
b. Installation is completed. Proceed to the “Programming the Changer” section.
The proper performance of your American Changer machine is directly related to the quality of the power it is
supplied. AC power fluctuations, including blackouts, brownouts, over voltages, sags, surges, and spikes may cause
the machine to miss pay. To ensure the most trouble-free operation, we strongly recommend plugging all of our
machines into a DEDICATED AC outlet (this means there are no other machines on location plugged into the same
AC line). A simple way to check if this is true is to turn off the breaker associated with our machine at the breaker
box. No other equipment on location should lose power.
Additionally, if your unit is located in an area prone to lightning storms or other sources of frequent power
disturbances, we also strongly recommend using an Uninterruptible Power Supply (UPS). If power is lost during a
payout to a customer, a UPS will allow your machines to complete the transaction that would otherwise not be
completed. In some cases, a UPS may also correct long-term under and/or over voltages on the AC line by
converting to the proper line voltage before the power reaches the machine.
Every American Changer machine has a surge suppressor built into the main logic board. This helps eliminate
power related noise problems, but it will not protect from substantial voltage spikes or nearby lightning strikes. If
this is a concern for your area, we recommend purchasing a commercial grade UPS with integrated surge
protection. NOTE: A POWER STRIP IS NOT A SURGE PROTECTOR.
WARNING:
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance
with the instructions manual, may cause interference to radio communications. It has been tested and found to
comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference when operated in a commercial environment.
Operations of this equipment in a residential area is likely to cause interference. In which case, the user, at his own
expense, will be required to take whatever measures may be required to correct the interference.

Section 1: System Description
INTRODUCTION
The Rowe BC-3500 Bill and Coin Changer is our top-of-the-line money changer that uses computer and money
changer technology which combines Rowe quality and reliability with maximum flexibility and ease of installation and
service.
The BC-3500 accepts and dispenses change for combinations of quarters, half-dollars, and dollar coins as well as
1, 2, 5, 10, and 20 dollar bills of United States currency. Denominations can be programmed to be accepted in many
combinations, as can the choice of coins paid out.
• A high security cabinet provides theft protection.
• A microcomputer in the Computer Control Center (CCC) selectively discriminates between denominations,
provides protection against bogus bills, and controls the change dispensing functions.
• Plug-in circuits and assemblies are featured for fast field substitution.
• Coin combinations and acceptable denomination programming is easily changed using the FUNCTION, UP,
DOWN, VALUE, and HOPPER buttons on the computer control center.
• Removable coin hoppers permit rapid bulk loading of coins.
• During setup, a special payout check feature ensures that the payout amount selected matches the
denomination accepted, unless tokens are being dispensed.
Refer to Figure 1-1 for the locations of the major BC-3500 components.
GENERAL OPERATION
The entire validation and payout sequence is controlled by a microcomputer to ensure the maximum security against
bogus currency and jackpotting. Refer to the Detailed Computer Board Operation in Section 4 for a complete
explanation of how the machine works.
Changing a Bill
Inserting a dollar bill in the transport starts a motor which movies the bill along the acceptor track. While in motion,
the bill is examined to determine whether or not it is valid. (During this time, the message “VALIDATING” will appear
on the computer’s display.)
If the bill is valid, a vend signal is transmitted to the dispenser and the bill drops into the bill stacker where it is stacked
flat against other valid bills. At this time, the message “PAY $1” (for example) for a $1 bill will appear on the display.
The one dollar change bucket opens, and the dollar’s worth of change drops into the coin cup.
25238801 1-1
BC-3500 Bill and Coin Changer
The coin hopper motors then operate, loading the correct number of coins from the left, center, and right coin hoppers
into the change bucket for the next payout.
If the bill is not valid, the bill transport motor reverses, returning the bill to the customer.
Changing Coins
Quarters, half-dollars, and dollar coins pass through the coin acceptor if the changer is so equipped. Solid-state coin
sensors start the payout cycle for these coins.
FUNCTIONAL DESCRIPTION
This functional description can be used to gain an overall understanding of the BC-3500 and its operation.
Bill Transport
The bill transport (see Figures 1-2 and 1-3) receives a bill as it is inserted by the customer. The bill is transported
through the transporter on a belt system, carefully examined and , if the bill is determined to be valid, is delivered to
the bill stacker.
If the bill fails any of the validation tests, the transport reverses and returns the bill to the customer. The bill will hang
in the transport inlet for a period of three seconds during which time the control computer will display a message
explaining the cause for the rejection. If the bill is not removed during this these three seconds, the computer will
display “PURGING ACCEPTOR” and a self-purging routine will begin. If the bill is removed in the three-second
period, the cause of the rejection will remain on the display for 30 seconds.

Section 1: System Description

Figure 1-3. Bill Transport (Bottom View)
Dual Bill Stacker
The dual bill stacker in Figure 1-4 has the capability
of stacking bills in two separate bill boxes. This feature
allows the bill changer to alternate between the two bill
boxes or to separate bills by denomination. This
function is controlled by the CCC, which activates a
solenoid-driven lever in the stacker. When this lever
is in its rest position, it acts as a stop to position the
falling bill in line with the upper bill box. When
energized, this lever drops out of the way and allows
the bill to fall to the lower bill box position. Once the
bill is positioned properly, a signal from the CCC
activates a triac drive circuit in the stacker. As the
stacker leaves home position, a single cam switch
closes and performs two functions:
Cam
Switc
25238801 1-3
Figure 1-4. Dual Bill Stacker
BC-3500 Bill and Coin Changer
• It holds the triac drive circuit ON and also activates the stacker monitor line to the CCC.
• When the stacker completes its cycle, the cam switch opens, stopping the stacker motor and deactivating the
monitor line to signal the CCC that it is ready for the next cycle.
Coin Acceptor
The coin acceptor checks the coins for which it was designed to determine their validity. Each coin is checked for
thickness, diameter, weight, and metallic content. If the coin is deformed or invalid, it is directed through the coin
acceptor to the coin return cup. Genuine coins are directed through the coin acceptor and actuate either of the two
solid-state coin switches located on the rear bottom of the slug rejector frame.
Jammed coins or slugs are cleared from the coin acceptor by a wiper arm on the coin acceptor, which is actuated
by the
COIN or BILL RETURN button. The coin inlet and chute deters cheating and jamming. The coin inlet and chute
can be opened for easy clean out by removing the lower thumbscrew and rotating the coin track up. Various coin
acceptors are available as order options. Use Table 1-1 that follows as a guide:

Section 1: System Description
Solid-State Coin Switches
As a coin passes through a slot in the coin switch assembly with any mechanical coin acceptor, it momentarily
interrupts an infrared light beam, causing a solid-state optical detector to send an electric pulse to the CCC. The
duration of this pulse is then checked by the computer to determine its validity. Valid coins will initiate the dispense
cycle. A separate infrared LED and optical sensor and photo-transistor pair is provided for each of the two possible
coin denominations accepted.
Coin Dispenser
The coin dispenser (see Figure 1-5) contains the necessary components to handle the coins. The escrow buckets,
the solenoid assemblies, the chute from the bucket to the channel mounted on the power control center, and the upper
coin chute from the coin detectors to the buckets are located on this assembly.
The three coin detectors, each consisting of an LED and a photo-transistor, detect the coins as they exit from their
respective hoppers and fall into the upper coin chute.
The upper coin chute directs the change to the escrow buckets.
The drive for the hoppers consists of three AC motors, which are also on the dispenser. These motors, as well as
the solenoids which open the bottom door of the escrow buckets, are controlled by signals from the CCC.
You can access the rear of the dispenser assembly by removing the two screws in the upper corners, grasping the
dispenser at the arrow, and tilting the entire assembly forward on its lower pivots.
When you replace the dispenser, be sure that you tighten down the two top screws securely. If these screws are
not tightened down, the entire dispenser assembly may tilt forward when the hoppers are unloaded or removed.

Coin or Bill Return Button
When the COIN or BILL RETURN button (see Figure 1-6) is depressed, a switch closes and sends a signal to the
CCC. The coin lockout coil in the coin acceptor is released and the transport motor rotates in the reverse direction.

Hoppers
The bill changer contains three coin hoppers (see Figure 1-7) which mount on the front surface of the dispenser
assembly and pivot forward from the bottom for loading, unloading, and removal (see Table 1-2 for required
hopper types and capacities).
The hopper transports coins to the detectors and coin chutes by means of a chain conveyor, which is driven from
below by a sprocket. The chain follows a serpentine path, so that excess coins fall back into the hopper ensuring
only one coin per pin enters the coin counting area.
The chain picks up coins from the bottom of the hopper and carries them up to the top, where they fall through the
upper chain guide ring and interrupt a light beam to a photodetector, which is mounted on the dispenser. The required
number of coins for a desired change combination are counted in this manner as the coins then fall through a closed
chute to the escrow bucket.
An agitator, which is mounted on the drive shaft of each hopper, agitates the coin load to minimize coin jams in the
hopper and ensure efficient coin pick up.
To reduce jams and minimize the need for cleaning, the hoppers in the BC-3500 also have Teflon-coated coin tracks.

NOTE:
The hoppers do not have an “Empty Sensor”. Empty hoppers are indicated by a failure
to count the required number of coins in a specified period of time (approximately three
minutes), however, if the changer shuts down frequently with an error relating to empty
hoppers when they are not, then the “serpentine coin path” should be cleaned as shown
in Section 3.

Section 1: System Description
EMI FILTER
The ElectroMagnetic Interface (EMI) filter removes undesirable electrical noise from the incoming power line. The
power transformer supplies 36 VAC and 22 VAC from which the rest of the system voltages are derived.
POWER SUPPLY
The ON/OFF switch controls power to the machine.
A 7-amp circuit breaker is in the power line to the bill changer. The power transformer is protected by a 2-amp circuit
breaker in the primary winding. A 7-amp and a 5-amp circuit breaker protect the secondary windings.
The power supply circuit board rectifies and filters the 36 VAC and 22 VAC to provide 40 VDC, 30 VDC (current
limited), 12 VDC, 8 VDC, and 5 VDC to the rest of the system. It contains indicator LED’s for the 40 VDC, 30
VDC, 12 VDC, and 5 VDC supplies. Note that the 12 VDC actually runs at about 14.6 V – this is normal.
TEST SWITCHES
The three TEST switches are used to manually initiate a change dispense cycle for each of the machine’s escrow
buckets. The computer will not recognize a TEST switch closure if the machine is in the process of validating a bill,
dispensing change, or in SHUTDOWN. Pushing a TEST switch will also cause the stacker to cycle.
POWER CONTROL RELAY
The power control relay switches the 40 VDC, 30 VDC, and 120 VAC supplies to the machine and 5 VDC to the
OUT OF SERVICE lamp. This relay is controlled by the CCC and is energized under normal operating conditions.
Under OUT OF SERVICE conditions, the CCC de-energizes the relay to disconnect the previously mentioned
voltages from the rest of the system and shut down the machine. In this condition, the +40 VDC LED on the power
supply board will be OFF, while the other three remain ON.
Computer Control Center
The computer control center (referred to as the “CCC” and shown in Figure 1-9) directs all of the operations of
the bill changer including both validation and change dispensing functions. It contains a microcomputer which controls
all of the major functions of the bill changer. It also contains the following controls and displays:

STATUS DISPLAY
The CCC contains many programming and self-diagnostic features which are described in the paragraphs that follow.
All messages are shown on a 16-character vacuum fluorescent display. In some cases, the message is short enough
so that the word(s) can be spelled out: in other cases the word(s) are abbreviated. The abbreviations are clear and
logical and each message is described in
Section 4
of this manual.
SERVICE AND CONTROL SWITCHES
The BC-3500 Bill Changer’s service features and programming options are controlled by six switches. The
descriptions that follow are introductory; follow the detailed procedures and instructions in Section 2 for specific
operating and programming information.
Programming/Normal
Select either the NORMAL operating mode or the PROGRAMMING mode.
NORMAL POSITION
In the NORMAL mode position, the changer operates in a normal manner. The CCC monitors all systems for faults
or customer input.
The VALUE and HOPPER buttons provide unique features while the machine is in the NORMAL mode.
Value Button
Pressing the VALUE button will cause the display to show the total dollar amount accepted since the temporary audit
value was cleared. Thus, if you clear this audit counter (see Section 2) each time you load the hoppers, you can
quickly see how much change has been paid out and thus determine whether or not the bill changer needs to be loaded
again.
Hopper Button
Pressing the HOPPER button will cause the display to show the last three denominations accepted. The most recent
denomination is displayed on the left side, the bill before that is displayed on the right side. If a test vend in included
in this list, the display will show: “TVL”, “TVC”, or “TVR” (depending on which TEST VEND switch was pressed)
in its proper position on the display. If a coin was accepted, the display will show “25”, “50”, or “$1C” on the display
in its proper sequential position (left, center, or right position).
When the PROGRAMMING/NORMAL switch is moved from PROGRAMMING to the NORMAL position, the
message “STORING NEW DATA” will be displayed.
PROGRAMMING POSITION
Setting the PROGRAMMING/NORMAL switch to the PROGRAMMING position allows you to inspect and/or change
the audit and setup information. This information is displayed on the status display and is selected and changed by
using the five pushbuttons that are described in the following paragraphs

Section 2: Installation & Programming
INSTALLATION
Installing the BC-3500 Bill and Coin Changer requires some instruction. For all types of installation, be sure that
a power source is convenient and that the changer is mounted level. Always use a grounded (3-prong) outlet.
NOTE:
For both security and safety reasons, Rowe strongly recommends that this bill changer be
securely anchored to the floor and/or wall. Please check the instructions that follow:
WALL MOUNTING
The following illustrations and procedures should be used for wall mounting. For concrete or masonry wall mounting,
use lag screws and lead anchors. For wood frame wall mounting, use lag screws attached directly into the wall studs.
If the wall is not flat, you may need to add spacer washers between the wall and the mounting plate.
If the changer is rigidly mounted to the wall, make the power input connection through rigid conduit into the changer
to meet U.L. requirements (see Figure 2-1).
For convenience, the back of the upper cabinet is dimpled in four places. You may choose to use these for the
placement of mounting bolts; if so, drill a 7/16- to 1/2-inch hole in each of these locations to accommodate a 3/8inch bolt (see Figure 2-2). Be careful not to drill into any internal BC-3500 components.
NOTE:
Be sure to remove all metal filings before putting the changer into service.

Section 2: Installation & Programming
CHANGE PAYOUT PROGRAMMING
Many different change combinations can be dispensed for the various denominations of money accepted. Change
payout programming is accomplished using the five buttons on the CCC. As mentioned earlier, there are mechanical
limitations which must be considered. The BC-3500 has three escrow buckets which will be preloaded with three
different payout values.
The CCC will automatically assign the highest payout to the right escrow bucket, the next highest denomination to
the left escrow bucket, and the smallest denomination to the center bucket. Even though the computer reassigns the
escrow bucket values automatically, you must be aware of and obey the capacity limitations of each of the escrow
buckets in order to maintain reliable operation. Table 2-1 shows the capacities of the three escrow buckets. You
must limit your payout combinations such that the total volume of coins in any escrow bucket does not exceed the
guidelines shown in the following table:
Table 2-1. Maximum Escrow Bucket Capabilities
Coins Escrow Bucket
or
Tokens Left Center Right
Dimes (.705” Dia.) 55 40 85
Nickels (.835” Dia.) 40 22 65
Quarters (.955: Dia.) 32 20 65
Tokens (.984” Dia.) 25 15 60
Dollar Coins (1.04” Dia.) 16 12 45
Tokens (1-1/8” Dia.) 8 6 25
In order to pay out for more than three denominations, the computer will, under certain circumstances, vend an
escrow bucket and hold that bucket door open while the remainder of the required payout is issued directly from
the hoppers to the coin cup. (Of course, after the entire amount has been paid, the escrow bucket door will be closed
and replenished under the computer’s direction.) One further rule is that the right bucket shall never exceed the
escrow value of the $10 bills.
As an example of how this works, consider the case where the denominations accepted are $1, $2, $5, $10, and
$20. The computer will assign the right bucket the escrow of the $10 bill; a $20 bill will then be an immediate $10
issue followed by $10 of direct payout. The $5 payout will be assigned in the left escrow bucket and the $1 will be
assigned to the center – with a $2 payout being an immediate $1 issue followed by $1 of direct payout. If you now
enable 25¢ coin acceptance, the escrow amounts would be reassigned: the 25¢ would be assigned to the center
bucket, the $1 to the left bucket, and the $5 to the right bucket. A $10 would be paid as an immediate $5 issue
followed by $5 of direct payout; the $20 would be an immediate $5 followed by $15 of direct payout. This new
feature is available with CCC P/N 65069059.

There are very few payout combinations which cannot be allowed. If you review them briefly, you will easily
understand why they cannot be used. Table 2-2 lists those combinations:

Using the rules of operations shown previously, it will be very simple for you to determine the escrow bucket values
for any allowable combination. This understanding is only important when using the
TEST VEND switches as they
only vend and replenish each of the buckets once. As an example, there is no $20 test vend.

$1 bills and coins are treated as the same for these purposes.
2
Quarters accumulated (25A) are treated exactly as 50¢ pieces for these purposes.

LOADING THE HOPPERS
Review Figure 2-4 before you begin.
1. Pull the hopper forward to its stop point.
2. Twist the top of a full coin bag one full turn. Grasp
the twisted top with one hand and hold the bottom
of the bag with the other. Invert the bag and insert
the top into the mouth of the hopper.
3. Slowly release the twist as the bag empties. Avoid
spilling coins into the changer. Empty the bag by
grasping it at the bottom and shaking it to dislodge
coins in folds of the bag. Push the hopper back into
place.
4. Load the change escrow buckets with change by
pressing each of the three TEST VEND switches one
at a time. Repeat this process for each test switch
and verify that the change that was dispensed is
correct.
Section 2: Installation & Programming
5. Coin I.D. stickers are supplied with the machine to
identify the coin denominations in each hopper.
Attach one of these stickers on each hopper so that
the coin denomination can easily be identified.
NOTE:
Hoppers may be loaded with either dollar coins, quarters, dimes, nickels, or tokens
unmixed depending on the type of hopper used. Make sure that the value of coins loaded
into the hopper agrees with the values programmed into the computer during the
HOPPER VALUE (HOP VAL) step of the setup.
UNLOADING THE HOPPERS
Refer to Figure 2-5 and unload the hoppers as follows:
1. Pull the hopper forward to its stop point.
Figure 2-3. Loading the Hoppers
2. Place the opening of the coin bag over the mouth of the hopper, wrapping the lip of the bag around the handle.
Grasp the bag and handle with one hand, tilt the hopper back, release the latch, and slowly tip the hopper
forward while holding the bag against the front of the hopper.
3. Hold the bag securely while you tip the hopper forward. Tap the hopper against the front shelf and return it
to the upright position. Repeat two or three more times to ensure that the hopper is completely empty.
