CNC4PC THC2 Torch Height Control
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
- Optoisolated output working at 5 to 24VDC or open collector
- Built-in Voltage Divider for connecting to the voltage on the torch or can use the 0- 10VDC from a voltage divider from the plasma.
- LCD Screen
- 10 to 30VDC Power Terminal (+24 Typical)
- Isolated Power Connection
- Magnetic base can place anywhere on the machine steel surface
- Din Rail Mountable.
- Divider input (16:1 – 20:1 – 40:1 – 50:1 – 1:1)
DESCRIPTION
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
DIVIDER INPUT (16:1 – 20:1 – 40:1 – 50:1 – 1:1)
OUTPUT SIGNALS
Voltage applied can be from 5 to 80VDC@50mA, outputs signal optoisolated Open Collector.

Turn knob
Push the knob to enter configuration mode.
Navigate through the configuration menu by pressing the knob.
Turn the knob to adjust the value.
Push the knob to set the value and navigate to the next parameter or until you
reach the run mode.
DESCRIPTION SCREEN
SET POINT (SP)
SP is the target voltage to be achieved.
VOLTAGE ARC (ARC)
Limit from 40 to 400VDC, True Voltage measured at the terminals or the voltage divider.
HYSTERESIS (HYS)
Is the tolerance or (+/-) voltage range used to generate an adjustment. The torch height is not commanded to adjust if the true voltage is inside the specified range. It can be between 2 to 32VDC.
DELAY TIME (DT)
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 (TEST)
Press the knob three times to enter test mode.
Turn the knob up or down to make the spindle move.
To exit test mode, press the knob once.
