Hello Joao,
Thank you for your purchase, I apologize for the inconvenience that you're having with the installation.
Now with your system, you mention at the THC up/down, and ArcOK signals are always on, and I think there could be caused by two things:
1. Improper wiring/mapping of the signals. Could you send us a picture of the wiring, so we can verify if you had indeed done the wiring correctly. Check the Input LEDs on the HiCON Integra to see if the THC connections are always active. The THC150 document also has a section for performing preliminary testing with a low voltage (0-10V) input if necessary. Also, because a plasma machine works with a high voltage cutter, it is very important to properly wire the earth ground to prevent electrical noise from accumulating in the system.
2. Software issues. If I recall correctly, you had modified the ArcPro screen that we provided with the package, which I assisted you with. Because we can only make guarantees for the components as they are (both hardware and software), we can't guarantee that everything will work properly once a user decides to make modifications outside the scope of the package. Also, there is a chance that you may have set the signals in Mach4 to be active low, in which case, the signal state polarity would be reversed which would cause the signals to register as active when they aren't physically activated. I think this may be something you should consider because the THC150, according to our testing should only have the THC UP or DOWN turned on one at a time, or have them both OFF. If the signal polarity were reversed, it would make sense that they both come up as active, while they are physically turned off.
Also, did you use the Mach4 profile that we had provided on the web? That had most of the configuration done for signal mapping and motion. For the most part, you'd have only needed to change the motor settings to match your motor specs, and set the THC parameters to what your machine required and what kind of material you would need to cut.
For the plasma torch itself, does your torch always feed back 27V DC only when the torch is actually turned on? I think I need a few more details on this.
