(Divide by 7 circuit) DB9 Cable to Connector on DTHC Module CT Transformer is an OPTION and must be ordered separately. It is used on Plasma Cutters that do not have an available ARC OK (Called other names by different Plasma manufacturers). The ARC OK provides feedback to the control that a valid pierce has been made and the arc current is at a level where motion can be released and the cut begun. The ARC OK is used only when the control has the THC enabled (Screen button). IT IS REQUIRED for Automated cutting with THC. All CandCNC THC Sensor cards have had the ability to use an external Current Transformer (CT) placed in the AC line to the plasma. The CT will only sense AC current so cannot be used on the DC side of the plasma. A new DC Current Probe (DCP) will be introduced in 2009 (late summer) that will read and sense the actual DC current at the WorkClamp lead and the REV14 card has the pads for the connector that will interface the DCP (Digital Current Probe) through the THC Sensor. To use the DCP you will have to have a DTHC Module Rev 8 or later. You can trade in older DTHC modules for the upgrade when you purchase a new DCP module. Page 38

See the location drawing next page. Detailed instructions for making these connections are in https://www.hypertherm.com/library/files/Manuals/Service%20Manual% 20%28SM%29/806110r0.pdf J19 Use 18 or 20ga insulated Hookup wire Insulation rating to 600V Min, Twist wires along the length of the run. NOTE: Hypertherm START (remote torch fire) DOES NOT WORK with the Hand Torch. You must find the Switch wires from the Hand torch and splice into them to be able to fire the torch remotely. See the following page to help identify the correct wires. START SIGNAL To TORCH - (ELECTRODE WIRES) DAMGER HIGH VOLTAGE WHEN TORCH is ON 3 14 J12 connector located on rear of unit. ARC XFR IMPORTANT: When making any connection inside the PowerMAX disconnect the unit from the AC Line (unplug it). Do not open the case with power on the AC line. THERE ARE DANGEROUS VOLTAGES present in the unit anytime it is connected to an AC source EVEN IF IT IS TURNED OFF. 4 12 J14 Tip Volts D6 CAUTION!
