Otis · 400 Elevator
Indicates that the coin acceptor is unplugged, leading to a complete inability to receive and validate coins. This will prevent any coin-based transactions.
Click steps to track your progress.
Inspect the physical connection of the coin acceptor cable at both the acceptor unit and the main control board for secure seating and any signs of dislodgement.
Inspect the coin acceptor's wiring harness for visible damage, cuts, or pinched sections from the acceptor to the control panel.
Measure the supply voltage at the coin acceptor's connector pins (if accessible) to verify it meets the specified operational voltage as per the Otis 400 documentation.
Check the Otis 400 elevator's diagnostic interface or service tool for the coin acceptor's status, looking for specific error codes or I/O states that indicate a 'disconnected' status.
