Troubleshooting

10.Troubleshooting and Cleaning the Coin Drop

When coins are placed into the coin slot, do they fall into the coin vault and does the

coin drop sensor register that coins have been entered? Refer to Figure 1 for the path

that coins follow when the drop is working properly.

Is proper

electrical

power

supplied to

the coin

drop?

Refer to the wiring

diagram supplied

with the machine

for connection

information.

Is the

machine

level?

Ye s

Refer to the

installation manual

supplied with the

machine for

instructions on

leveling the

machine.

Is the coin

drop clean?

Ye s

1. Disconnect electrical power to the machine and the coin drop.

2. Remove the coin drop from the machine.

3. If lint is preventing coins from rolling through the coin drop, blow compressed air

through the coin entry and along the side of the coin drop. Refer to Figure 2.

4. Insert a coin into the coin drop. If the coin does not fall through the drop, continue

to step 5.

5. Remove the cotter pin from the top of the drop. Refer to Figure 2. Save the pin for

reinstallation when the cleaning of the coin drop is complete.

6. Move the metal clip closer to the sensor so that it comes off of the frame. Refer to

Figure 2.

7. Remove the coin return from the coin drop frame. Refer to Figure 3.

8. Check the path in the coin drop for lint and residue. If lint or light residue is present,

use a cotton swab to remove it. If heavy residue is present, it may be necessary to

first scrape off the excessive residue and then to use a cotton swab dipped in water

or isopropyl alcohol to remove the remainder of the residue. Refer to Figure 4.

9. Check the return pendulum to verify it swings freely. If the pendulum does not

swing freely, spray the pendulum pivot point with Teflon-based lubricant and move

the pendulum back and forth 3 times. An additional application of Teflon-based

lubricant may be necessary to ensure the pendulum swings freely. Refer to Figure 5.

10. Check the coin drop sensor for dust or dirt on the eyes. Wipe the eyes with a dry

cotton swab. Refer to Figure 6. IMPORTANT: Do not use isopropyl alcohol to clean

the electronic sensor or eyes.

11. Reinstall the coin return onto the coin drop frame.

12. Reinstall the metal clip and slide toward the coin insert slot. All cotter pin holes

must line up.

13. Reinstall the cotter pin.

14. Place the coin drop on a level surface to verify that coins follow the correct path to

the coin drop. It may be necessary to lift the coin drop to allow the coin to follow

through the sensor.

15. Reinstall the coin drop into the machine.

16. Reconnect electrical power to the machine and coin drop.

17. Insert a coin into the coin drop to verify that the coin drop is operating properly.

If the coin drop does not operate properly after the above steps have been

completed, corrosion of the metal or vandalized components within the coin drop may

be preventing it from functioning properly. Replace the coin drop.
