Configuring the CNC4PC THC-2 Plasma Torch Height Control for your plasma CNC machine involves several key steps. First, you'll need to connect a 10 to 30VDC power supply (24VDC is often recommended) to the POWER terminals, ensuring correct polarity. For safety, it's best to use the divided voltage input. Connect the torch voltage to the DIVIDED INPUT terminals. The module provides optoisolated Open Collector output signals; be sure the applied voltage does not exceed 5 to 80VDC @ 50mA to prevent damage. To access the configuration menu, press the designated button on the LCD screen. Navigate the menu using the appropriate buttons, and adjust parameters such as SET POINT (SP), VOLTAGE ARC (ARC), HYSTERESIS (HYS), DELAY TIME (DT), and TEST MODE (TEST) to suit your cutting needs. To configure the divided voltage, press the appropriate button three times to enter the setting mode, adjust the value, and set the split voltage. Always refer to the wiring sample in the user manual for a basic illustration, but remember that actual wiring might differ depending on your setup. Safety is paramount when working with CNC machines; remember that the THC-2 module is not a fail-safe device. Consult the CNC4PC THC-2 manual for detailed instructions.
