What does Low Acceptance mean?

Indicates a low coin acceptance rate, specifically that more than 20% of the last 255 coins processed were identified as slugs. This suggests issues with coin validation or slug detection.

Common Causes

  • High percentage of rejected coins (slugs) by the coin acceptor.
  • Malfunction of coin validation sensors or algorithms.
