Auditor Autobank - Vend Assembly Output Sensors

Output Sensor Sensitivity Adjustment

The output sensor is used to verify that tubes are ejected when vending, that tubes do not stick in a partially ejected condition, and it also is used as a theft deterrent. Tubes cannot be ejected from chutes without passing through the path of the output sensor. When the output sensor beam is interrupted and neither VEND nor UNLOAD is in progress, the safe records the interruption and displays the message EVENT RECORDED. The sensitivity of the output sensor is adjustable. The following is the adjustment procedure for the output sensor. A small flat tip screwdriver is required for this adjustment.
1. Check that there is no blockage in the path of the output sensor.
2. Locate R7 on the Driver Board. It is the output sensor trim. R7 is a blue rectangular trim pot located immediately next to the DROP light on the Driver Board.
3. R7 is a 50 rotation trim pot with no end-stop, so use caution and follow these directions carefully.
4. Rotate R7 clockwise until a "click" is heard and/or felt.
5. Make note of how many rotations it took until it clicked (too many or too few indicates that R7 was not properly adjusted before this adjustment).
6. When R7 is fully clockwise the DROP light is usually off.
7. Rotate R7 counter-clockwise. When the DROP light comes on continue to the greater of 3 additional rotations or 25 full rotations from the end.
8. When R7 is properly adjusted the DROP light is lit (with no beam interruption). Test by vending tubes.
9. Verify that changing light conditions in the ambient environment and people walking close by in front of the safe do not cause EVENT RECORDED messages and do not prevent proper operation.
