Coin Inlet Blocked
Otis · 400 Elevator
What does Inlet Blocked mean?
Indicates two coins were sensed at the inlet sensor but failed to make it to the changer within 10 seconds. This suggests a blockage or malfunction in the coin path between the inlet and the changer.
Common Causes
- Obstruction in the coin path after the inlet sensor, preventing coins from reaching the changer.
- Malfunction of the coin routing mechanism.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Inspect the coin inlet and the coin path between the inlet and the changer for any foreign objects, debris, or mechanical obstructions.
- 2
Verify the functionality of the inlet sensor and any subsequent coin path sensors by testing with known coins or observing diagnostic feedback.
- 3
Inspect the coin path for signs of wear, misalignment, or damage to guides, gates, or other moving parts that could impede coin travel.
- 4
Check all electrical connections and wiring between the coin inlet system and the coin changer unit for looseness, corrosion, or damage.
- 5
Clean the coin path thoroughly to ensure smooth coin travel and remove any build-up that could increase friction or cause intermittent blockages.
