ThankYouComeAgain Posted September 6, 2011 Share Posted September 6, 2011 I really need your help. Last week I was told that my AP 7600 machine (with a revision door) was taking dollar bills but not giving change. I performed a few test vends using dollar bills and could not recreate the problem. Rather, I found that that my machine was taking the dollar bills, giving the desired product, AND 4 quarters back. I called a service out to take a look, but before he could look at it, I performed more tests and the issue was non existent, and so I told the service guy not to come see the machine. This week, I was told that the same machine was not reading coins. I performed some tests on various trays, and for sure, the machine read my coins that I inserted. I was then told that the persons losing money used all quarters - so I performed tests using all quarters and had no problems at all. I have a theory that, when I open the door to get change/cash out to perform the tests, that the machine goes back to normal. Any thoughts? EDIT: The model number of my bill changer, which is only 45 days old, is as follows: NBM 3140 The changer model number, I couldn't get it as it was installed, however, the front of it says CCM5G. Both are made from CONLUX. Link to comment Share on other sites More sharing options...
Technivend Posted September 7, 2011 Share Posted September 7, 2011 Your problem does sound like a changer issue so I would first start there. The problem you will have us the Revision door uses a new board and nit the original AP board and it sounds as if every tine you open the door there is an interlock switch that is resetting the machine. The only way to eliminate this is to tape in the switch so when you open the door it stays in the vend position so you can se what may be happening.

sideshot Posted September 8, 2011 Share Posted September 8, 2011 as a rule i always run a few test vends before i open the door as it could be a pinched harness or something putting pressure on the coin mech and check that the machines propely grounded Link to comment Share on other sites More sharing options...

Technivend Posted September 29, 2011 Share Posted September 29, 2011 On the AP it was just above the display. It should be a white switch. I don't know if it is eliminated with the revision door or not. Link to comment Share on other sites More sharing options...

ThankYouComeAgain Posted September 30, 2011 Author Share Posted September 30, 2011 it will probably look similar to this, The interlocking switch! Then that was EXACTLY what I was thinking will solve the issue. Thank you so much guys for pointing this out. I'm very happy with the community of help I keep seeing on this board.
