Low Acceptance

Low Coin Acceptance Rate

Otis · 400 Elevator

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.

  3. 3

    Check all cabling and connectors between the coin validation module and the main elevator control system for secure fit and integrity.
