thickness). Since all coins we vend are from
20-30mm, this rarely changes.
4. When a bill is finally inserted into the
validator bill slot, the bill will be pulled inside.
The MLB display for the validator shows
“BUSY
” while the validator compares what
the bill looks like to examples in memory.
After the bill is accepted, the validator tells
the MLB that it is OK to accept, and asks if it
is OK to stack the bill. The MLB will then
check the coin hopper status before sending
an OK. The Validator stacks the bill, but the
MLB waits until the Validator sends a code
stating the bill has been stacked before
proceeding.
5. Now that the bill type accepted is stored in
the MLB flash memory, the program reads
the settings for type and number of coins to
be dispensed. The program then computes
the payout using the received bill type and
the coin type(s) selected by the user, and
divides that number by the total coin hoppers
functioning. This will be the payout for each
hopper.
6. The program then sends secure DATA words
to the hopper informing it of the amount of
coins to dispense.
7. When the hopper is finished, it sends a
different DATA word to the MLB. The MLB
then turns off the “Busy” display, and the
changer returns to the STANDBY mode, with
the red LED flashing once per second, until
another bill is inserted.
OUT-OF-SERVICE CONDITIONS
Out-of-Service conditions occur in the changer for
the following reasons: blown fuses, validator
faults, coin acceptor faults, or hopper faults.
Blown Fuse:
An AC power spike in line voltage
or a bad transformer on the Power Supply board
can cause a blown fuse. If the primary fuse
blows, the indication is that the green LED on the
power supply will not light.
1. Replace the fuse. If the green LED now lights
then there was a spike.
2. If it does not light and the fuse blows again,
disconnect the hopper and validator
connectors and try again. If the green LED
stays lit, reconnect each component one at a
time until you find the one blowing the fuse.
3. If the fuse still blows with all components
removed from the MLB, the power
transformer is shorted. To test the
transformer, use a multimeter set for ohms
and measure across the primary (40ohms)
and the secondary (1.5ohms).
Validator Faults:
When a validator fault occurs,
the validator’s EEPROM shuts down the validator
and sends an error code to the Logic Board’s LCD
display. The Out-of-Service light on the front of
the machine will illuminate for a validator fault.
1. Validat. Full – The Bill Stacker is full of bills
and should be emptied.
2. Validat. Motor – Motor failure. Either the
Stacker or Transport motor has failed;
replace the unit.
3. Validat. Sensor – One of the sensors inside
the validator has failed. Check for a jammed
bill; if that is not the cause, repair or replace
the validator.
4. Validat. Checksum – Checksum failure. The
validator’s Logic Board programming has
been corrupted; repair or replace the
validator.
5. Validat. CashBox – The Bill Stacker has
been removed from the validator and should
be replaced.
6. Validat. NoComm – There is a
communication failure between the changer’s
Main Logic Board (MLB) and the validator.
This may be a temporary condition while one
of them is completing some task, or the cable
harness may be loose or unplugged, or the
validator may need to be repaired or
replaced.
7. Validat. Disabled – The MLB cannot enable
the validator, due to an internal error inside
of the validator. This may be a
communication issue, and may be temporary.
8. Validat. String – The changer’s Anti-
Stringing protection has shut down the
machine’s operation. Basically, more money
has been paid out in less time than allowed
by the system’s settings (see pg. 14 for Anti-
Stringing protection setup). Wait the allotted
time, or reset the MLB to resume operation.
9. Validat. Pulse – The pulse validator being
used has been disabled. Check the unit and
repair or replace as necessary.
10. Busy – This message is displayed whenever
the validator is in the process of validating
(accepting) or stacking a bill.
Coin Acceptor Faults:
The following Coin
Acceptor faults are only for changers equipped
with a Money Controls SR3 Coin Acceptor using
ccTalk serial communication protocol. The Out-of-
Service light on the front of the machine will NOT
illuminate for a Coin Acceptor fault, but the error
message will be displayed on the LCD display.
1. CoinAcc. NoComm – There is a
communication failure between the changer’s
Main Logic Board (MLB) and the coin
acceptor. This may be a temporary condition,
or the cable harness may be loose or
unplugged, or the coin acceptor may need to
be repaired or replaced.
2. CoinAcc. EEPROM – The EEPROM on the
coin acceptor’s logic board has an error.
Repair or replace the unit.
3. CoinAcc. Coils – There is a general fault in
the unit’s inductive coils. Check the coin
path, or “flight deck”, for dirt or an
