Test Buttons
The board’s test buttons are used to simulate the payouts for dollar and coin acceptance. When a test button is
depressed, the board pays out according to the dip switch settings. To simulate the payout for a $10 dollar bill, test
button “$” would be pressed ten times in rapid succession. To simulate the payout for the coin value test button
“coin” is pressed. On three hopper models, the test buttons are located on the service panel as well as the control
board. If the “$” test button is pressed for an impossible value, such as 9 or 11, no payout will be made. The reset
button must be pressed before attempting additional tests.
Time Out Protection
The board has a built in “Time-out” feature that shuts the board down in the event that a coin count is not sensed
for twenty seconds. This feature offers extra protection against jackpotting.
Troubleshooting Tips for Switching Power Supply
The LED on the switching power supply indicates AC power is supplied and that the unit’s internal fuse is good.
The +5vdc supplies power for the board’s logic, incandescent count sensor bulbs and empty lamp. The +12vdc
powers the optional alarm and supplies power if a 12 vdc validator is installed.
BC3500 Control Board Installation Instructions
The following instructions are for the conversion of a Rowe BC3500 changer with known good hopper motors,
count sensors, and red LED emitters. The meter in the Power Control Center Assembly is also reused.
1.
Remove the three hoppers from changer.
2.
Depress the bucket test switches so the coins in the Coin Dispenser Assembly are released from the escrow
buckets.
3.
Unplug power cord from the wall outlet.
4.
Remove the bill transport by unplugging the connector on the right hand side and sliding it forward and out of
the tracks.
5.
Remove the bill boxes from the stacker assembly.
6.
Remove the stacker assembly by unscrewing the two ¼” screws. It may be necessary to hold the nuts under the
assembly with a pair of pliers. Unscrew the two ¼” screws that secure the bottom of the stacker assembly to
the cabinet. Disconnect the harness from the upper rear right hand side and pull the stacker assembly forward
out of the changer. Replace the two screws and nuts on the track rails.
7.
Unscrew the two 3/8” bolts that secure the Coin Dispenser Assembly (6-50275-10) and tilt unit forward. Slide
assembly to the left and forward so it is no longer resting on the side pivot rods. Reach to the back of the
assembly and unplug the wiring harness.
8.
Remove the Coin Dispenser Assembly and set the unit on a workbench for modification of the bucket
assembly.
