12 fault codes documented
One flash (LED) — Bill box is full
The red LED on the logic board flashes once, indicating that the bill box has reached its capacity and needs to be emptied.
Two flashes (LED) — Bill box lid not latched
The red LED on the logic board flashes twice, signifying that the bill box lid is either open or not properly secured.
Three beeps — Unsuccessful test vend
During a test vend cycle, three beeps indicate that the motor for the selected item did not complete the vend test successfully. This could be due to a jam or motor issue.
Three flashes (LED) — Check bill path
The red LED on the logic board flashes three times, indicating a potential issue within the bill path, such as a jam or debris.
Four flashes (LED) — All bill accept switches are off
The red LED on the logic board flashes four times, meaning all the switches related to bill acceptance are in the 'off' position.
Five flashes (LED) — Bill jam or sensor error
The red LED on the logic board flashes five times, indicating a possible bill jam or a problem with the sensors responsible for detecting bills.
Six or more flashes (LED) — Reset or service required
The red LED flashes six or more times, indicating a more serious issue. This may require a power cycle reset or professional service.
Error 3 — Loss of coin mechanism communication
The controller has lost communication with the coin mechanism. This could be due to a connection issue or a problem with the coin mechanism itself.
Error 4 — NOVRAM checksum error
This error indicates a problem with the non-volatile RAM (NOVRAM) checksum. This suggests a potential issue with the control board.
No LED flashes — Check power and harnessing
When the red LED on the logic board shows no flashes during self-check or operation, it suggests an issue with the power supply or the wiring to the validator.
Motor error xx 1* — Too little motor current
This error indicates that the motor for a specific selection (indicated by 'xx') is drawing too little current, suggesting an electrically open motor circuit.
Motor error xx 2* — Too much time to complete vend
This error means the motor for selection 'xx' took too long (over 12 seconds) to complete its vend cycle. This is often caused by a jam or a slow-moving motor.
