Coins Not Accepted

Troubleshooting

This article covers coin jams in your Conlux MCM5 coin mech, and what to do when your coin mechanism will not display the credit after inserting a coin. 

Symptoms/Considerations

Flashing red or yellow diagnostic LED's on the upper right corner of the coin mechanism.

Coins going to the coin cup or coins not getting credited to the display

Take a moment to familiarize yourself with the components of the coin mechanism in the diagram below.

Look at your coin mech and you'll see two columns of vertical buttons which are labeled as User Interface Buttons. (Enlarged view below)

Above the A button is a red LED. If it's a solid red LED, this indicates everything is working properly. Coins will be accepted. Should the red LED be flashing, this indicates a coin jam.

To clear the coin jam simply press down on the white Acceptor Gate Lever located to the right of the Coin Funnel.

If the jam is not cleared by this action, locate the Coin Channel Cover (View diagram above). Press the tab on the left side of the Coin Channel Cover for access. Once open, verify if coins are jammed behind the bright green mechanism. Firmly tap the bright green mechanism allowing the coins to pass though the mechanism, clearing the jam. Once the jam is cleared, the red LED indicator will become solid. 

Returning back to the User Interface Buttons, note the B button has a yellow LED above it. If it's a solid yellow LED, this means that the coin cassette is working properly. Coins will be accepted.

Should the yellow LED be flashing, this indicates an issue with the coin cassette or the mechanism directly below the coin cassette. 

PLEASE NOTE: Troubleshooting the coin cassette consists or three separate tasks. One task could solely eliminate the problem making the next tasks unnecessary.

Task #1 

(Do not skip any steps in this task)

1.  Locate the cassette latch.

2. Press and hold the latch down.

3. Pull the latch outward.

4. Lift the coin cassette out of the coin mechanism.

5. Turn the vending machine power switch off.

6. Turn the power switch back on. 

7. Replace the coin cassette after you hear the bill validator cycle.

8. Verify the yellow LED above the User Interface Buttons has become solid. 

9. Verify coins are being accepted.

If coins are accepted the additional tasks are not necessary.

Task #2 

1.  Locate the cassette latch.

2. Press and hold the latch down.

3. Pull the latch outward.

4. Lift the coin cassette out of the coin mechanism and place it face-down on a table.

5. Follow the clear coin tubes to the bottom. There you will find the white plastic Payout Slide. The white plastic Payout Slide must be completely inserted for the coin cassette to operate properly.

(Pictures of the Payout Slide below)

6. To verify that the Payout Slide is inserted properly, press it downward firmly into the coin tubes so that it is flush with the coin tubes. 

5. Turn the vending machine power switch off.

6. Turn the power switch back on. 

7. Replace the coin cassette after you hear the bill validator cycle.

8. Verify the yellow LED above the User Interface Buttons has become solid. 

9. Verify coins are being accepted.

If coins are accepted the additional tasks are not necessary.

If coins aren't accepted after completed both tasks, contact Customer Support.

Troubleshooting

This article covers what to do when you have a coin jam

Symptoms/Considerations

You will see a flashing red light or a yellow diagnostic LED on the upper right corner of the mech

Your mech will not display the credit after inserting a coin

This will work on any Conlux MCM5 product and may work on other mechanisms as well. 

Look at your coin mech and you'll see two columns of vertical buttons, labeled as the User Interface buttons.

Above the A button is a red LED. A solid red light means that everything is working properly and coins will be accepted. A flashing red light indicates a coin jam. To clear the coin jam press on the white lever to the right of the funnel. 

After the jam has been cleared, the red light will become solid. 

Above the B button is a yellow LED. A solid yellow light means that the coin cassette is working properly and will be accepted. A flashing yellow light indicates an issue with only the coin cassette or the mechanism below the coin cassette.

The bottom of the coin cassette should have a thin white plastic piece between the coin tubes and the grey bottom of the coin cassette. Without it, change cannot be dropped into the coin return slot. Check to see if this piece is pushed in all the way. 

Once you've checked this, keep the coin cassette out of the coin mechanism, turn the machine off. Turn it back on and wait for the start up noises from the bill validator, then insert the coin cassette back into the coin mechanism. At this point the yellow flashing light should become solid. Insert coins from the front and they should be accepted.
