DN5591 Acting funny

Hi

 

I Have a DN5591 (software Version 30.51)

 

Today when I was  looking at my numbers in my USA Technologies Acct (G9) I noticed a sale for $654.11 for a can soda.

 

When I went to the location I noticed that every time you hit ANY selection it would display price and drop the item for FREE. I even tried a credit card...it authorized the card ...the item dropped...the the reader said 0 charged..but the item still dropped. (but USA never charged the card)

 

It was look the vending machine was set to FREE Vend...but it would still display the price of the item before it gave it to you for free.....very weird. 

 

When the item dropped for FREE...USA Tech recorded it as a sale....but NO money was ever put in machine and item dropped.

 

I dont think this has anything to do with USA ...because it will still drop sodas for free without a credit card.

 

I restarted the vending machine and every thing returned back to normal....and NO more free drinks

 

This is Twice this has happened in 2 months...I guess I am a little concerned

 

I have tried to duplicate the problem and can not.

 

Has this happened to any one else with a DN5591? Beside these 2 occurrences the machine has been working perfectly.

I've not seen that issue before and especially because it free vends while displaying the true price I would suspect a bad logic board. Just this week I replaced a 5591 board because it would gradually show every selection out of service before a factory reset would only fix it for a day or two. His board had a bad cap on it at the very least. Even if you had a vend sensor problem not detecting a vend it wouldn't flagrantly give all products away.

Another clue to it being a bad board is the .11 sales figure since the board will never do penny pricing. If you need a new board send me a PM and I can get you one.

Hey AZ

 

What about the display board ...will I have to change that out to?

 

This control board has software version 30.51...doesn't the new control boards have to have a different display board?

 

I think the newest software version is 30.81 which will not work on my current display board....kinda confused about  the display board?

The typical 5591 board version is 30.61 which will work with the older display as well as any earlier version. The 30.81 version requires the newer display and corresponding display harness. I can get you a new display and harness if you are going to use the newer board version.

I am not familiar with cc readers yet, but is it possible that the cardwwasusedforapurchase and it never closed the transaction? The accumulated sales are being charged to the card? I am just guessing of course.

I would start by checking the ground on the outlet and cord.

Next I would replace all the florescent lamps.

Them I would reset the board to factory setting.

 

Only if the problem reoccurred after this work would I replace the board.

 

If this board turned up on a repair bench this problem would be very unlikely to occur on the bench it is very likely just get a reset and a new sticker and off to the next customer.
