B. Computer Control Interface (CNC)
NOTE
Used when Remote Control RC6010 or Standoff
Control SC11 are not used.
The computer control interface allows a mechanized sys-
tem to interface with a computer or other control device.
NOTE
Refer to Section 4.03-D for more information on
the CNC connections.
CNC cables can be interfaced to the Power Supply using
one of the following methods:
NOTE
Refer to Appendix 7 for CNC Interface Schematic.
• Connector (J15) at the rear of the Power Supply
• Internal terminal strip in the Power Supply
Depending on the equipment ordered and the cables sup-
plied connect the CNC cable per one of the following:
1. Using supplied CNC cable
Connect the supplied Power Supply/CNC Cable
to the Power Supply rear connector J15 labelled
REMOTE CONTROL.
2. Using customer supplied CNC Cable
a. Remove the Left Side Panel from the Power
Supply as viewed from the front of the unit.
b. Locate the internal terminal strip (TB2) near
the heatsink.
c. Feed the CNC cable through the small strain
relief at the rear of the Power Supply.
d. Connect the CNC cable to the terminal strip
(TB) per the following chart:

NOTES
Connections to TB2 positions 1 through 4 are acti-
vated with a switch or contact closure.
If Remote Control is not used the Enable Signal
circuit must be closed.
Connections TB2-7 and TB2-8 are normally open
(NO) contacts.
Connections TB2-9 and TB2-10 are selectable for
normally open (NO) contacts or 24 VAC.
e. Secure the CNC cable by tightening the two
screws on the strain relief.
f. Reinstall the Left Side Panel.
C. Optional SC-10 or SC11 Standoff Control
Cable
For mechanized systems, the Standoff Control automati-
cally finds height and maintains torch standoff with a high
speed torch lifter motor. The unit consists of a remote
operator's control, torch lifter motor, and all cables re-
quired for installation. It is ordered and shipped sepa-
rately. Refer to the SC-10 or SC11 Standoff Control In-
struction Manual for more information.
Depending on the Standoff Control to be used connect
the cable per one of the following:
