1 A 24 VDC from the CNC is necessary to use this feature.
2 A 24 VDC (500 mA) and return (GND) from the CNC or controlling device to the expansion PCB are necessary for redundant remote on-off
for the expansion PCB and input to the control PCB. Hypertherm recommends the use of a separate cable between the remote on-off input
and main control PCB.
3 Estimated arc voltage analog output (0 V – 10 V ). The default ratio is 30:1. For information about how to use the XPR web interface to
change the voltage ratio, refer to Use the XPR web interface to change the arc voltage output scale on page 166.

Use these steps to change the voltage ratio through the XPR web interface.
Before you begin:
■
You must have a computer-based device with a screen, a web browser that has support for the latest
web standards, and wireless access.
■
You must set up a router that has access to a local network. Use the instructions for the router to do
this. If you have problems setting up your router, speak to your system administrator.
■
You must know the SSID and passphrase for the router.
1. Do the procedure in Use AP mode to connect on page 169 to connect the wireless set-up device to
the plasma power supply.
2. Go to the Other screen.
