Ohmic sensor and thcad 10

Hello group I am trying to make the hypersensitivity circuit with thcad-10, in the diagrams I see that they use a ponwer source of 24v + and 24v-, I want to know if I can use a source only of 24v + and with what resistance would I use it, I am about to finish and it would be great help in this matter.

Thanks for the answer, now that I'm putting together another question, if I use hypersensitivity with thcad-10 for sensing, do I need another thcad card? Because in the inputs in + and in - the voltage division enters and in the sensor ohmic in these inputs the torch and the table are used, I am confused.

If you are using thc with a thcad and want to do ohmic sensing you need another thcad.

Luckily I have another one, now I need to know which is the pin of the thcad which gives the signal to the mesa card that the metal is already sensed

Its not as simple as that. You need to search the forum for ohmic3.comp and connect it via hal before you install Plasmac. Then you connect the output pin from ohmic3.comp to the plasmac input.

Ok, I think I go the way of relays and that, in the 5 guidelines of the plasma guides the first point indicates that the torch should always be isolated the tip of it to use this system, what does that refer to and if it is isolated as it would make electrical contact for the ohmic sensor, I am using a lotos lpt5000 plasma ... Sorry for my english.
