SECTION 4: MAINTENANCE
BA30 CLEANING PROCEDURE FOR
SALT WATER POLLUTED UNITS
NOTE: Petroleum-based cleaners and freon-based
propellants can damage plastic and some electronic
components. Scouring pads and stiff brushes may harm
the protective coating on the circuit boards and can mar
the plastic. These items should never be used when
cleaning the BA30 bill acceptor.
Procedure
1. Remove power from the bill acceptor.
2. Remove the bill acceptor from the vending machine.
3. Open the bill box lid and verify that the stacker plate
is in the standby/home position. If it is not in the
home position, apply power and observe that the
stacker plate returns home.
4. Remove the bill box.
WARNING: If moisture is present, allow the unit to dry
thoroughly before applying power to avoid possible
shock hazard. If the stacker plate does not return to the
home position, remove power and carefully remove the
bill box to avoid damaging the bill box and/or stacker
plate.
5. Remove the lower housing.
6. Remove the bottom cover from the lower housing.
7. Run hot water (110°-140°F) over the lower housing
from the top and bottom. Using a soft brush, gently
clean any salt residue. Use a soft, absorbent cloth to
clean residue off the lower housing. If the trans-
former gets wet, allow the unit to dry for 24 hours
before applying power.
8. Remove the front mask. Using hot water and a soft
brush, clean the front mask, upper sensor board and
main frame anti-pullback levers.
CAUTION: The motors are not protected from water,
therefore the unit must be held in a manner that pre-
vents water from running over them.
9. (For units prior to serial number 109300187 only)
Remove the position sensor cover on the crossbar
and carefully lift the LED from its mount. Clean all
salt residue from the mount, sensor hole and detector
area. (The detector can be seen through the sensor
hole and is located in the chassis.) Replace the
position sensor cover.
CAUTION: Protective coating on the LED leads should
not be damaged.
10. Verify the anti-pullback levers move freely and that
the spring returns them to their extended position.
11. Allow the unit to dry thoroughly.
12. Clean the magnetic head using a swab and isopropyl
alcohol.
13. Replace the front mask.
14. Replace the lower housing cover.
15. Place the lower housing into the main frame.
16. Remount the bill box.
17. Apply power and insert bills to verify the unit is
functioning properly.
