Remote on-off switch requirements

You must supply the remote on-off switch, or switches, for your cutting system.

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.

A remote on-off switch lets you supply electric power to or remove electric power from the gas connect console, TorchConnect™ console, and some parts of the plasma power supply from a location that is remote from the main power source. A convenient location for a remote on-off switch is near the Computer Numerical Control (CNC). As an user or installer, you must supply the remote on-off switch, or switches, for your cutting system.

A feature of the control Printed Circuit Board (PCB) is that it offers redundancy to one remote on-off switch. When the redundant remote on-off feature is selected, signals from two remote on-off switches are necessary for the plasma power supply to work.

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. Make sure to use a separate cable between the redundant remote on-off input and main control PCB.
