Cryptopay for Unitec Wash Select

[Greg Pack]

Hi Greg, interesting you should ask and yes my paystation is exhibiting the same as you describe. DRB had me test those pins with a voltmeter. My voltmeter may not be the best and it’s digital so the read on the 5VDC came out to 4 and the read on the 12VDC came out to 11. The 24VAC was reading at 27. DRB was suspecting the power supply but they were not certain so they wanted to test for another hour by having me unplug and plug back in different connectors. Sometimes the screen goes blank and just start making a clicking sound. Other times the paystation will accept payment and then say proceed but the wash doesn’t start. I’ve restripped several wires, I’ve remove the cryptopay swiper thinking that might have something to do with it, and I’ve checked for moisture in the box.

Try disconnecting the LEDs on the display and I/O board and see if your 5VDC voltage come up

Just so I have a good understanding of what you are referring to, it’s the little red lights on each board? I’m fairly new at this so I don’t want to screw anything up.

No it's the lights that "backlight" the screen when it's dark. If you will look on each individual display there is a two wire connector that connects to the I/O board (The big board on the back of the door) They illuminate the displays at night. Try disconnecting all five of those and see if your voltage rises.

I would also recommend getting a multimeter that will read voltage by the 10ths. In this case, getting your voltage up from say 4.2 to 4.8 volts might make the problem go away.
