Why is my NRI Cash Counters & Coin Sorters coin validator not accepting coins?

  ohaasAug 1, 2025
  If your NRI Cash Counters & Coin Sorters coin validator isn't accepting coins, here's what you can check: * **Power Supply:** Ensure the ribbon cable is correctly connected to both the coin validator and the machine, and verify the machine is receiving voltage. * **Coin Runway:** A dirty coin runway can cause issues. Open the flight deck and clean the coin runway. * **Inhibit Signals:** Multiple inhibit signals could be the culprit. Check that the machine isn't activating the common inhibit signal line, the single inhibit signal line assigned to the coin, or inhibiting via ccTalk command. Also, verify the DIL switches on the rear of the device aren't inhibiting the coin or if only the narrow coin channel is enabled.
