Otis · 400 Elevator
Indicates a tube sensor error within the coin changer. This affects the proper detection, sorting, and dispensing of coins in the tubes, potentially causing miscounts or jams.
Click steps to track your progress.
Inspect the coin tubes and the sensor's detection area for any physical obstructions, jammed coins, or accumulated debris that might interfere with sensing.
Check all wiring and connectors associated with the tube sensor for secure connections, signs of wear, or damage.
Measure the supply voltage to the coin changer module and the specific tube sensor, if separately powered, comparing against the nominal values specified in the electrical schematics.
Verify the tube sensor's mounting, alignment, and cleanliness of its sensing surface to ensure proper coin detection.
Verify the sensor's status and diagnostic readings in the system's HMI or service tool to confirm its signal output when coins are expected or absent.
