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

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 flashes

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.

xx 1*

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.
