I have just transplanted an Ardac bill acceptor part# 1x224-0502 serial 12700872 with the currency acceptor model# 88x4001-17 part# 1x223-0005 serial# 04600969/087. I took this unit out of a poker machine that has a bad power supply and could not test the bill acceptor at that time. I put it in the machine I need a bill accepter in and tested. After several adjustments and a cleaning, I finally got past error code 5 and now I keep getting error code 2 which says, "No run-check machine for credit-in cycle-empty of coins or product return from escrow". This unit does not have a bill collector so the bills would just fall on the inner floor of the arcade (like my other machines). I do not have a manual, nor can I find one online. While I have tinkered with bill acceptors in my other machines, this is my 1st time transferring one to another. I have never messed with the pins or the wires before. I do not have a program or cleaning card. I purchased this old poker machine with this bill acceptor as is with no instructions or paperwork so I'm starting from scratch. The poker machine I installed it in does work, it does accept coins, so I am able to play the machine. It just takes forever to put in quarters and get 100 credits or more. I did add a button to add coins faster, however if you push the button too fast, you get a jam error on the arcade. Thats why I'm hoping to use the bill acceptor for this unit. Any help would be appreciated, thank you.
