Start signal is
on at
power-up
Plasma start signal input is
active during power-up of
the power supply.
1. Stop or clear the cutting program. The plasma start signal
to the plasma was not dropped after the last cut.
2. Verify that the CNC interface cable is not damaged.
3. Remove CNC interface cable from PCB4 and look for an
open circuit between pins 15 and 34.
4. If the circuit is closed either the CNC is issuing a plasma
start or the CNC interface cable is damaged.
5. If circuit is open, and D44 is illuminated with the CNC
Interface cable removed from PCB4, replace PCB4.
053
Low shield
pressure
Shield pressure is below
lower limit of 0.14 bar
(2 psi).
1. Verify gas supply pressure and that a sufficient volume of
gas remains in your supply.
2. Verify gas regulator settings on the front panel with cut
chart.
3. See Setting the supply regulators (Installation section).
4. Fuel-gas only – Perform leak test procedure
(Maintenance section).
054
High shield
pressure
Shield gas pressure is
above upper limit of
6.8 bar (99 psi).
1. Verify gas supply regulator settings. See Setting the
supply regulators (Installation section).
2. Verify pressure settings on the front panel with cut chart.
3. Solenoid at off-valve is not opening. Verify power to valves,
disconnect plasma and shield hoses exiting off-valve. If
pressures decrease, a valve is not functioning or no power
to the valve.
061
No plasma
gas type
Plasma gas has not been
selected.
1. If you have a base system (no fuel-gas console), replace
the control board (PCB4)
2. If the system has a fuel gas console, replace the fuel-gas
console control board (PCB2)
062
No shield gas
type
Shield gas has not been
selected.
1. If you have a base system (no fuel-gas console), replace
the control board (PCB4)
2. If the system has a fuel gas console, replace the fuel-gas
console control board (PCB2)
063
Low preflow
inlet pressure
Inlet pressure is < 4.1 bar
(60 psi).
1. Verify Air or nitrogen gas supply pressure and that a
sufficient volume of gas remains in your supply.
2. Verify that the Burkart valve is functioning properly.
3. Put the selection switch in the SET position. The 3-digit
LED shows the supply pressure. The pressure reading
should be between 6.2 bar and 8.3 bar
(90 psi and 120 psi).
