THCAD charge from mode 1 to mode0?

Hi! I have diagnosed that my reed relay fort the arc ok is not working. I don’t get a signal when firing my plasma. So i’m thinking about changing from mode 1 to 0. Can I do that without running the wizard? What do I need to change? And what is then suitable max and min voltages? I’m going to contact my Chinese supplier for the plasma for a new relay, but this is a quicker way for me to be up and running.

A picture of how you have the reed switch configured would help.

Ie. have you wrapped the cable around it about three turns.

Sorry for double posting. Thought that I failed to post the first time. The plasma cutter is a Herocut 55X with a cnc port. I have tried measure with a multimeter and I get no contiunity when the arc is established. I can see on the 7i96 that it ain’t receiving the signal. So I think the relay is bad

i feed a 24v signal (direct from power supply) to reed relay/ arc ok port and has it connected to input of 7i96

The relay is indeed working! I opened up the machine and checked if I got a signal when activating with a magnet and it worked. I then went back to the cnc plasma and tested it and checked all the cables and everything is OK with the wires. I run some shapes in LinuxCNC but I will not get any signal when I waits for arc ok (not on 7i96 card and not I LinuxCNC). If I then ignore Arc ok then I will get a signal( both on 7i96 card and in plasmac (shows arc ok). I can’t figure out what’s different. Can my pierce height be to high? Can I have a delay some and when the plasma fire and burn away the material the contact is broken ? I really can’t understand why it behaves differently when I ignore arc ok. 

So my thoughts is that i will use the thcad card instead for meassure arc ok.

I found the problem. It was the pierce height. When I lowered it it now work (approx 2.5 mm height now)
