Section 4: Troubleshooting
Accept, Payout, and Replenish Modes
During normal operation, the display will reflect each state the machine goes through as it happens. When a bill is
moving in the transport, the message “VALIDATING” will appear. After validation, during the stack and vend cycles,
the display will show the message “XX PAYS - - -”. The XX indicates the denomination just accepted and the -’s
represent the number of coins from the left, center and right hoppers needed to refill the bucket. During replenish,
as coins pass through the detectors, the displayed coin counts will be reduced until all three reach zero. The machine
will then return to the STANDBY mode.
Reject Mode
While the machine is validating a bill, several things may cause the bill to be rejected. When a bill is rejected, the
transport will reverse returning the bill and the status display will show a reason for the reject. This reject message
will stay on the display for about thirty seconds, then the walking dash will erase it.
Out of Service Mode
If a condition exists that will prevent proper operation, the changer will enter the OUT OF SERVICE (or SHUTDOWN)
mode. The most common cause of this condition is that the changer is out of coins or tokens, but other malfunctions
will lead to this state.
When the control computer detects such a condition, it immediately de-energizes the power control relay and coin
lockout solenoid. This causes the 120VAC, 40VDC, and 30VDC to be switched off to all components and the
OUT OF SERVICE lamp to come on. The display will begin to flash an error message.
The next pages will provide explanations of and troubleshooting hints for all of the reject and shutdown messages.
