Repair Steps & Checklist
Click steps to track your progress.
- 1
Inspect the coin tubes and the sensor's detection area for any physical obstructions, jammed coins, or accumulated debris that might interfere with sensing.
- 2
Check all wiring and connectors associated with the tube sensor for secure connections, signs of wear, or damage.
- 3
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.
- 4
Verify the tube sensor's mounting, alignment, and cleanliness of its sensing surface to ensure proper coin detection.
- 5
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.
