Connect for Communication
- Communication methods for XPR® cutting systems
  There are multiple communication methods to fully operate the plasma cutting system.
- Requirements for EtherCAT®
  This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with EtherCAT® cables.
- Requirements for serial RS-422
  This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with serial RS-422 cables.
- Requirements for discrete
  This information prepares you to connect the plasma power supply to the Computer Numerical Control (CNC) with discrete cables.
- VDC3 PCB installation for AVC with RS-422 and discrete-only connections (if applicable)
  The VDC3 Printed Circuit Board (PCB) installation instructions are for Arc Voltage Control (AVC) with serial RS-422 and discrete-only connections.
- Requirements for the XPR web interface
  You can connect to the XPR® web interface through Wi-Fi® with Access Point (AP) mode or through a direct connection with Ethernet Local Area Network (LAN).
- Requirements for Ethernet LAN (wired)
  Before you use an Ethernet Local Area Network (LAN) interface to connect to the XPR® cutting system, review this information. This information prepares you to use an Ethernet LAN interface.
- Requirements for manual-set mode
  This information prepares you to use EtherCAT®, serial RS-422, Ethernet Local Area Network (LAN), or the XPR® web interface through Wi-Fi® or Ethernet LAN to enable or disable manual-set mode
- Change the device that has control
  Use these steps to make sure that the correct device has control of the plasma power supply.
- Use ohmic contact sense
  You can use internal or external ohmic contact sense. No action is necessary for internal ohmic contact sense. To use external ohmic contact sense, make the following modification to the ohmic wiring inside of the TorchConnect™ console.
- Install a remote on-off switch
  As an alternative to using the main power source, do these steps to install your own remote on-off switch so that you can control power to the gas connect console, TorchConnect™ console, and other parts.
  - Examples of output circuits
    If it is necessary to design your own circuit to use the remote on-off feature, you can refer to these output circuit diagrams as examples.
  - Examples of input circuits
    If it is necessary to design your own circuit to use the remote on-off feature, you can refer to these input circuit diagrams as examples.
- Install a redundant remote on-off switch
  Do these steps if you want to use the redundant remote on-off switch.

Warning

ELECTRIC SHOCK CAN KILL

The plasma power supply contains dangerous electric voltages that can seriously injure or kill you. Even if the plasma power supply is turned OFF, you can still get a serious electric shock if the plasma power supply remains connected to an electric power source.

Use extreme caution if you do diagnosis or maintenance tasks when the plasma power supply remains connected to an electric power source and the outer cover or panels are removed. All work that requires removal of the plasma power supply outer cover or panels must be done by a qualified technician. Refer to the Safety and Compliance Manual (80669C) for more safety information.

Remove the jumper from pin 1 and pin 2 of the J14 connector.

For the pinout of J14, refer to Pinouts for the discrete interface cables.
Install your own interface.

Use the examples in Examples of input circuits and Examples of output circuits to design your circuit.

When the remote on-off switch is set to OFF (disabled), electric power stays ON (active) to the following parts:

Power-indicator Light Emitting Diode (LED) on the front of the plasma power supply
Control Printed Circuit Board (PCB)
Control transformer (can be different on input and output)
24 V power source
120 VAC on the power distribution PCB
220 VAC on the power distribution PCB
120 VAC to the input side of the 48 V power relay
