INDICATORS
B
A. Main Power Switch - controls the input power to the
fan, water cooler, and the interface PCB. The amber
light to the left of the switch indicates power is ON.
B. Output Current Dial - sets the cutting current when
current settings are made from the console front panel
(remote/panel switch in PANEL position).
C. Remote/Panel Switch.
1. Panel Position - allows output current to be set by
the output current dial as described above.
2. Remote Position - allows the output current to be
set by the CNC with an analog dc signal.
0-10 V dc = 0 - 100 Adc
D. Cutting Current Meter - displays the actual cutting
current.
E. Cutting Voltage Meter - displays the actual cutting
voltage.

F. Pilot Arc High/Low Switch is used to select pilot arc
current.
G. Coolant Flow Fault Indicator - indicates low coolant
flow. The light will come on momentarily when the
console is turned on and then go out.
H. Plasma Gas Pressure Fault Indicator - indicates low
plasma gas pressure.
I. Start Gas Pressure Fault Indicators - indicates low
start gas pressure.
J. P/S Temp Fault Indicator - indicates over tempera-
ture fault condition in the inverter power source.
K. P/S Fault Indicator - indicates fault in the plasma
control PCB in the inverter power source.
L. Over/Under Voltage Fault Indicator - indicates input
voltage is above or below the tolerances of the PCU
console. Will latch until power is recycled by main
power switch.
M. Emergency Stop Fault Indicator - indicates CNC
emergency condition.
