Need Nayax Help

[Big Chris]

So, my wife and I recently acquired our second car wash. This site has 6 Nayax readers for 6 SS bays. I'm having some trouble and need some advice, I literally have 7 days experience with these readers and yesterday 2 of them quit working......... Well they will read and process the credit card but they do not activate the bay. I spent several hours yesterday working in the bays with the mechanic I inherited with the wash. He's a nice young man, and exceptionally intelligent with great problem solving skills. However he is admittedly completely self taught with the Nayax readers.

I've got Dixmor LED 7s and Nayax Pulse Readers, I am using count up. Here is how he had them wired, and up until very recently they all worked. The other 4 units are wired like this and they function.

The mechanic reports, that if we hook the Nayax units up to 24 VAC (it's really ~29VAC in the bays) the Nayax units burn out. (I have not attempted to connect to 24VAC for fear of him being correct)

I've read the posts of connecting the green wire from the Nayax harness to the white/black on the LED7s but first I've got questions:
1) has anyone had issues with connecting their Nayax units to 25-30VAC?
2) is there programming that needs to be done to make the connection to the LED7 function or is it truly plug and play? .
3) If I wanted to keep the setup as listed above, should I be using a 5VDC relay instead?

Thanks in advance,

1. I've heard from multiple sources that nayax will burn up from anything over exactly 24vac(and the specs state 24vac as the max), we use a cheap ac/dc converter from Amazon to turn the 24vac at bay into 12vdc, cheap insurance and we use 12vdc relays.

2. It should be plug and play if they haven't altered any programming earlier. We have 6 bays setup like this with older led6 units when they used to work with nayax. No we use a relay setup that can work with any timer.

3. We couldn't make 5vdc or 24vdc relays work reliably(I suspect you are running into the problems we had with the 24vdc relays, work sometimes and don't work sometimes), we could only get the 12vdc low level relays to work reliable, this is what we use on all of our nayax setups now - bays(count up) and vacs(count down)
