+10V @ 10ma. For Remote CC Pot – Previously CCM versions if one wanted to use a potentiometer for the Remote
Analog Current Control (CC) input an external 10 V supply was required for Pot High.. Now an isolated (from main
plasma circuits) 10V supply is provided. Recommended value of the pot is 5K or 10K.

Plasma Marking Select (Remote) – Plasma Marking, available only with DFC 3000, may be activated with a contact
closure between TB3-1 & TB3-2 if SW8-4, DIP switch on the CPU board (smaller of the 2 CCM boards), is also on.
Opening the connection between TB3-1 & TB3-2 switched back to normal cutting mode. For Ultracut power supplies It
is OK to leave SW8-4 on whether you are marking or not.
