Description
1 Power Supply Output Voltage (ARC V +)
2 Power Supply Output Voltage (ARC V -)
3 High Side of START Signal (+15 vdc)
4 Low Side of START Signal (Common)
5 One Side of OK-To-Move Signal
6 Other Side of OK-To-Move Signal
NOTES
ARC V+ Power supply positive output voltage
(work lead) connection to TB position 1 through a
100k resistor.
ARC V- Power supply negative output voltage
(torch electrode) connection to TB position 2
through a 100k resistor.
START + signal at TB position 3, 15 vdc at 10 ma,
must be brought low by connecting it to START -
at TB position 4, using a switch or relay contact,
to start the plasma torch.
OK-To-Move is a relay, rated at 115 VAC/28 vdc
at 2A, connected to TB positions 5 and 6 which
closes for the OK-To-Move signal when the cut-
ting arc is on.
Make sure all connections to the Terminal Block
(TB) are secure.

f. Reinstall the terminal block into the scket on the
Filter/Voltage Divider PC Board.
g. Secure the CNC cable by tightening the strain relief.
h. Reinstall the Right Side Panel.
B. Optional Standoff Control SC11 Cable
The Standoff Control SC11 automatically finds height and main-
tains torch standoff with a high speed torch lifter motor. The
unit consists of a remote operator’s control, torch lifter motor,
and all cables required for installation. It is ordered and shipped
separately. Refer to the Standoff Control SC11 Instruction
Manual for more information.
The standoff control remote cable connects to the recep-
tacle J22 (CNC Control) on the rear panel of the Power
Supply.

C. Optional Remote Hand Pendant Control
For automated systems, the optional Remote Hand Pendant
Control allows the operator to control system start and stop
functions from a remote location.
Connect the Remote Hand Pendant cable connector to the re-
ceptacle J22 (CNC Control) on the rear panel of the Power Sup-
ply.
