Page 14: Introduction
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.
Page 15: Changing 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.
Page 16: Dual Bill Stacker
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.
Page 17: Coin Acceptor
BC-3500 Bill and Coin Changer • It holds the triac drive circuit 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.
Page 18: Solid-State Coin Switches
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.
Page 19: Coin Or Bill Return Button
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. 1 - 6...
Page 20: Hopper Capacities
Section 1: System Description 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”...
Page 21: Temporarily Out Of Service Lamp
BC-3500 Bill and Coin Changer Temporarily Out of Service Lamp This lamp is located on the top door above the bill and coin inlet area. It lights whenever the machine is empty of change or shutdown due to some malfunction. In addition, the 40 VDC LED will normally go out if the out of service lamp is lit.
Page 22: Emi Filter
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 switch controls power to the machine.
Page 23: Status Display
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.
Page 24: Denominations Accepted
DENOMINATIONS ACCEPTED The BC-3500 can accept quarters, half-dollars, and dollar coins as well as 1, 2, 5, 10, and 20 dollar bills of United States currency. All of these denominations can be selected in combination with other denominations. However, due to mechanical limitations and other considerations, some combinations cannot be used.

Page 28: 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.
Page 29 BC-3500 Bill and Coin Changer 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: Table 2-2. Acceptance Combinations Which Are Not Allowed 50¢...

Do not uncover the VI cell. Wait five seconds for the transport to start to cycle reverse-forward-reverse-forward-reverse.
Page 42: Dispensing Tokens
Section 2: Installation & Programming DISPENSING TOKENS A unique situation exists when dispensing tokens while in the mode. The ability to payout a progressive bonus is allowed, even if payout is normally an extended vend of a lower denomination. Normally, in the mode or when paying out coins, some denominations require an extended dispense–direct NON-MC payout–replenish cycle.
Page 43: Token Control
BC-3500 Bill and Coin Changer Token Control When dispensing tokens using the bonus payout, it is difficult to maintain token count control. The amount of money changed does not directly indicate the number of tokens dispensed. In the mode, a special token counter is used.
Page 44: Accessing The Fast-Feed Menu
Section 2: Installation & Programming Note that the Fast-Feed information is maintained in memory until it is manually cleared by using the FUNCTION button. This applies even if another condition occurs. As an example, if the Fast-Feed Shutdown OUT OF SERVICE condition is entered at 11PM on Saturday and the changer returns to service 10 minutes later and continues to operate until 3PM on Sunday when it runs out of coins, the display will be flashing “...

ERROR RESET MISCELLANEOUS The BC-3500 was designed to be simple and easy to troubleshoot. Please take time to study the operation of the machine and to study the explanations of the various status messages. The following is a list of incidental characteristics that may be of interest to the operator and service person: 1.
Page 47 4. If power is disrupted during a dispense or replenish cycle, the machine will immediately reset upon power turn on. There will be an incorrect change load in one of the buckets. This is the same as all previous Rowe changers.
Page 48 Section 3: Routine Service INTRODUCTION In order to maintain control over money used for change dispensing, each changer should be loaded with a predetermined amount of cash. The inventory should be checked monthly as a precaution against malfunction and theft. Inventory control is most easily accomplished by using the replacement method of servicing. Using this method, all bills and coins are removed by the route man and the empty hoppers are refilled with a predetermined amount of change.
Page 49: Filling And Emptying The Bc-3500
BC-3500 Bill and Coin Changer 7. The magnetic head must have a bevelled edge on both front and back to keep both bill edges from becoming caught in forward or reverse. 8. Nylon rollers on the magnetic head assembly must rotate freely. No dirt, moisture, burrs, projections, or rough spots can be on the magnetic heads or magnetic head holder.
Page 50: Emptying The Changer
Section 3: Routine Service EMPTYING THE CHANGER To empty the changer of all coins, first empty all hoppers according to instructions on the label on the top door. When the hoppers are emptied, some coins will remain in the change buckets. Press the test switches, one at a time, to release these remaining coins.
Page 51: Cleaning The Hopper Coin Path
BC-3500 Bill and Coin Changer CLEANING THE HOPPER COIN PATH The coin tracks are Teflon coated to minimize dirt buildup. It may still be necessary to clean them at regular intervals, as dictated by the number of vends and the environment, to prevent dirt accumulation in the coin path.
Page 52 Section 3: Routine Service WARNING: Chain lubrication is not normally required or recommended. Do not use detergents to clean the hopper. The hopper has been factory lubricated and detergent cleaners may destroy this lubrication. Using the Nylon hopper cleaning brush supplied with each machine, remove all dirt from the angular sides and flat surfaces of the serpentine coin path as shown in Figure 3-4A.
Page 53: Change Bucket Lubrication
The coin dispenser change bucket door pivots, links, hubs and bell cranks are factory lubricated with light machine oil. Rowe specification Number 00137900 oil or 3-in-1 Electric Motor Oil can be used. If change bucket is worn beyond repair, order and install one of the kits listed at the end of the Parts Catalog in this manual.
