BC-3500 Series - Rowe International

BC-3500 Bill and Coin Changer
Sequence Descriptions
1. During sequences 1 and 2 the control computer is performing internal tests on itself. Several things may indicate
trouble. If the LED in the transport comes ON and stays ON and the display stays blank, there is a problem
with the microprocessor on the control computer board. If the LED in the transport continues with the power
up sequence but the status display stays blank, there is a problem with the display and it associated circuits
on the computer control board.
The XX on the display represents a software version number that will be displayed there.
Example: Version 1.0 software will be displayed as VERSION 10. The version number displayed will match
the version number visible through the hole in the lower left corner of the control computer assembly.
2. During sequence 3, the control computer is checking the integrity of its own program.
3. During sequence 4, the control computer is testing the Random Access Memory (RAM). If the RAM test does
not pass, the message on the status display will say “RAM TEST FAILED”. The machine will not continue the
power up sequence and the LED in the transport will remain ON.
4. During sequences 5 and 6, the control computer is checking the machine configuration. If the configuration
is the same as when the machine was turned OFF, it will go to normal standby operation. If the machine code
does not match (a CCC board from a BC-1200 installed in a BC-3500), the display will show “MACHINE
CODE ERR”. If the configuration changed due to low battery voltage or some other reason effecting the RAM,
the display will show “SET UP REQUIRED”. In either case, the machine will require reprogramming.
5. Sequence 7 is the stand by condition. A dash walks back and forth across the status display and the LED in
the transport is ON.
MACHINE STATUS
The status of the machine is shown on the status display of the CCC during all phases of operation. The following
section will describe the status messages displayed.
Standby Mode
The STANDBY mode is the normal, waiting to accept money, mode. All four voltage LED’s on the power control
center are lit. All three LED’s on the dispenser are lit. Then the inlet LED (VI) in the transport is lit. There is a dash
walking back and forth across the display. All motors and bucket solenoids are OFF. The transport motor is OFF.
The coin lockout solenoid is either on or off depending on whether coins are enabled or not. The out of service lamp
is off.
In the STANDBY mode, the HOPPER and VALUE buttons on the CCC have special functions. When the VALUE
button is pressed, the status display will show “AMOUNT $XX-XX”, where XX-XX is the amount of money that has been
accepted since this amount was last cleared. When the HOPPER button is pressed, the status display will show “LAST
XXX XXX XXX”, where the XXX indicates the last three denominations paid out. The denomination on the left is the
most recent, the denomination in the center paid before the one on the left and the denomination on the right paid
before the center denomination.
