  • Page 5: Terminal Board

    TERMINAL BOARD POWER Requires a 10 to 30VDC at 100mA Power Supply. Typically, +24vdc are used. “This board is electrically isolated through an internal built-in DC-DC converter.” WARNING: Check the polarity and voltage of the external power source and connect the 10VDC to 30VDC and GND.

  • Page 6: Torch Voltage

    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.

  • Page 10: Hysteresis (Hys)

    HYSTERESIS (HYS) This is the voltage range that you is allowed before sending correction signals. Adjustment signals are sent if the voltage is the hysteresis amount below or above the set point voltage set. If the set point voltage is 100 volts and a hysteresis is set to 2, then DOWN signals will be sent if the voltage reaches 103 volts or above and UP signals sent if the voltage is reaches 97 volts or below.

  • Page 11: Delay Time (Dt)

    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 four times to enter test mode. Turn the knob up or down to make the spindle move.

  • Page 12: Divided Voltage Configuration

    DIVIDED VOLTAGE CONFIGURATION Press the knob three times to enter the setting mode Turn the knob to adjust the value. Press the knob to set the divided voltage to be set. This setting can also be used to fine tune the voltage read. User’s Manual Page 10...

  • Page 13: Analog Smooting

    ANALOG SMOOTING This data smoothest the voltage reading. This can be a value between 1 to 200. The analog voltage can be noisy or jumpy. This setting will allow for a more stable reading. User’s Manual Page 11...

  • Page 14: Anti-Dive

    ANTI-DIVE If the plasma torch moves over empty space, the THC will see it as a voltage spike. Setting a max value will allow the THC to ignore the voltage spike and prevent the torch from diving. This can be a value between 10 and 100 %. User’s Manual Page 12...

  • Page 15: Auto_Setpoint

    AUTO_SETPOINT Automatically establishes the Set Point based on the cutting height that is set. The set point is calculated by measuring the true voltage for a couple of seconds after the delay time (when it starts cutting, then setting this voltage as the set point or target voltage. ACTVATE DISABLE If Auto_SetPoint is activated, the set point adjustment is disabled and the word Auto is...

  • Page 16: Delay To Sample Target Voltage (D2Stv)

    DELAY TO SAMPLE TARGET VOLTAGE (D2STV) When using the Auto Set Point option, you can configure a delay before start taking the sample reading. This to allow for the torch voltage to become stable when it starts cutting. 6.10 SAMPLE TIME This is the time that is going to take reading the voltage that is going to be used to determine the Auto Set Point.
