I installed NAYAX readers and, aside from some minor programming issues, was able to get the NAYAX unit on my vacuum with a Dixmor LED 7 timer without too much difficulty. Once I got through to the right tech support guy, he was able to get my minor issue with that unit resolved right away.
However, my bay meters have Dixmor LED 6 timers and it has not been as straight-forward. As you will see in historical posts, the chips in the LED 6 units changed a few years back and the units now require a relay to work properly. After talking to tech support and multiple others at Nayax, I figured out this was my issue so I ordered the recommended relays. I installed them this evening and followed the wiring diagram. I initially wired up the input side of the relay and everything seemed fine (light on relay turned on and stayed on). I then connected up everything on the output side and there were a few buzzing noises and then the Nayax units shut down (not good - like something short circuited). I was able to get the Nayx unit to start back up but it now seems that the ground wires coming from the Nayax reader have a charge. If I connect the VCC wire to the DC+ terminal and the GND wire to the DC- terminal, nothing happens whereas before the light on the relay turned on. However, I can connect the VCC wire to the DC+ terminal and then connect to the DC- terminal directly to the meter box and the light on the relay then comes on. I am concerned that my Nayax reader may be damaged from something that wasn't working right with the initial wiring.
Has anyone else been able to successfully wire up a Nayax with a newer Dixmor LED 6 timer? Do you have any better or different wiring diagrams then the ones below? I am checking with a reliable contact at Nayax as well but I may not hear back until Monday with it being the weekend. I imagine that someone has encountered this issue before and am hopeful that someone can give me some advice. Can I ground the relay directly to the common wire rather than through the GND wire on the Nayax reader? If so, the relays seem like they will power up. However, I am concerned about doing more damage if I follow the wiring diagrams for the remainder of the terminals on the relay since the initial attempt did not seem to work so well (and may have damaged the Nayax units).
Thanks in advance!
