OVERVIEW This module allows you to control the height of the plasma torch head relative to the workpiece during plasma CNC operation, it supports either raw torch head voltage or input of 0-10VDC, the ARC OK, UP and DOWN outputs are isolated. FEATURES •...
TERMINAL BOARD POWER Requires a 10 to 30VDC at 100mA Power Supply. Typically, +24vdc are used. “This board is electrically isolated through a DC-DC converter.” WARNING: Check the polarity and voltage of the external power source and connect the 10VDC to 30VDC and GND. Overvoltage or reverse-polarity power applied to these terminals can cause damage to the board, and/or the power source.
TORCH VOLTAGE NOTE: It is preferable to use the divided voltage instead of the torch voltage. The Torch voltage can be very high and there could be many safety implications in wiring this to the controller. The high voltage could also be a possible source of noise. Use it as a last resource. OUTPUT SIGNALS Voltage applied can be from 5 to 80VDC@50mA, outputs signal optoisolated Open Collector.
UCCNC CONFIGURATION UCCNC Configuration for THC-3 on C76 or C94 Used software: UCCNC Version 1.2115 http://www.cncdrive.com/UCCNC/setup_1.2115.exe STEP 1: Start by making a backup of the existing installation: Make a backup of the configuration and file installation, we recommend creating a backup of the current installation by right-clicking in the current installation folder and zipping it.

Make a backup of the original M3 and M5 macros by zipping them into the same folder, just so you may have access to the original macros if you need to revert the installation later. Then replace the M3 and M5 macros for the profile you are configuring: STEP 5: Configure the new Plasma Screen: Set UCCNC to use the new screen that you just copied:...
ARC VOLTAGE Limit from 40 to 400VDC, True Voltage measured for the plasma. V-RANGE (HY) Is the tolerance or (+/-) voltage range used to generate an adjustment. The torch height is not commanded to adjust if the true voltage is within side the specified range. It can be between 2 to 32VDC.
THC DELAY Torch motion starts the number of seconds you set as DT after the ARC signal is determined. This can be a value between 0.1 to 9.9 seconds. TEST MODE • Select test mode button on the screen, the test led will turn on. •...
