Delivery Sensor Verification

Confirming the delivery sensor's proper alignment, cleanliness, and functionality is crucial to prevent operational errors like double-vends or false failure reports.

Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.

  • If the sensor is physically damaged or misaligned, escalate this to a qualified technician for sensor adjustment or replacement.
  • If the sensor fails to trigger during a test vend, escalate this to a qualified technician to check the sensor's electrical connection and function.
  • If the sensor appears functional but the system reports failure, escalate this to a qualified technician to check the associated control logic.

    Inspect the sensor optics or paddle for any visible dirt, misalignment, or physical damage.

    Stop conditions
    • If the sensor is physically damaged or misaligned, escalate this to a qualified technician for sensor adjustment or replacement.
    • If the sensor fails to trigger during a test vend, escalate this to a qualified technician to check the sensor's electrical connection and function.
    • If the sensor appears functional but the system reports failure, escalate this to a qualified technician to check the associated control logic.

    Expected: Initial condition is documented before deeper diagnosis.

    Manually trigger the delivery mechanism and observe the sensor's reaction to confirm it registers the action.

    Stop conditions
    • If the sensor is physically damaged or misaligned, escalate this to a qualified technician for sensor adjustment or replacement.
    • If the sensor fails to trigger during a test vend, escalate this to a qualified technician to check the sensor's electrical connection and function.
    • If the sensor appears functional but the system reports failure, escalate this to a qualified technician to check the associated control logic.
