Fault Indicator Lights
Coolant flow will show low coolant flow. When
•
unit is turned on, the light will briefly show a fault
and then go out.
Plasma Gas Pressure fault indicator -- low
•
Plasma Gas Pressure. Torch will not fire when
indicated. Not used for the EFC. Not used for the EFC. Not used for the EFC. Not used for the EFC.
Start Gas Pressure fault indicator -- low start gas
•
pressure. Torch will not fire when indicated. Not
used for the EFC. used for the EFC. used for the EFC. used for the EFC.
P/S Temp fault indicator -- over temperature in the
•
inverter power source. Power source will shut
down.
P/S Fault Indicator – fault in plasma control PCB
•
in the inverter power source. Power source will
shut down.
Over-Under Voltage fault Indicator -- indicate
•
input voltage is above or below the tolerances of
the PCU console. Will latch until power is recycled
by main power switch.
Emergency Stop fault indicator -- shows CNC
•
Interlock condition. Power Source will not work.
Cutting Current Meter (A) -- Displays actual
•
cutting current in amperes.
Cutting Voltage Meter (V) -- Displays actual
•
cutting voltage.
Control Remote/Panel Switch
Panel Position – Output current is set by the
•
output current dial
Output Current Dial – sets the cutting current
•
when current setting is made from the console
front panel. Dial reads 0 to 99.9 amps. 70.0 amps
shown.
Remote Position – output current is set by the
•
CNC (or remote pot) with an analog dc signal
0-10 Vdc = 0-100 Adc
