The dip switches on the new board must match the dip
switches on the old board.
Switch number 1 determines if the board is being used in
an HPR130 (OFF position) or an HPR260 (ON position).
Switches 2 and 3 are used when the plasma system has
more than one power supply in series (also referred to as
multi-drop systems). Switches 4 through 8 must be in the
OFF position. See the wiring diagrams in your instruction
manual for more information on multi-drop systems).

on the new control board to match the jumpers on the old control board in the corresponding locations. See the figure
