Gas system
error
Auto Gas
Only
A failure has occurred in
the gas system.
1. Verify that cable number 5 (power supply-to-gas console
control cable) is not damaged and is properly connected to
PCB3 and to the rear of the gas console.
2. Verify that cable number 6 (power supply-to-gas console
power cable) is not damaged and is properly connected
inside the power supply and to the rear of the gas console.
3. Verify that D1 (+5 VDC) and D2 (+3.3 VDC) are illuminated
on PCB2 inside the gas console. These LEDs indicate
power to PCB2.
4. If power is present at PCB2 and PCB3 and both gas
console cables are good, then PCB2 or PCB3 has failed.
Use the CAN tester to verify which board needs to be
replaced.
031 Start lost
Start signal was received
and then lost before an arc
was established.
1. If a mechanical relay is being used to provide the HPR with
a start signal, this relay is either bouncing when activated or
the contacts are faulty. Replace the relay.
2. Inspect interface cable for damage; faulty crimps, or poor
electrical connections.
3. If interface cable is good and a relay is not driving the start
input, the CNC is dropping the start signal before a steady
state arc has been established.
032 Hold timeout
Hold signal was active for
longer than 60 seconds.
1. Check the interface cable for damage. The hold wires may
be short-circuiting inside.
2. The CNC is maintaining this input, it could be waiting for an
IHS complete input from another torch.
3. If CNC interface cable is good and it is a 1-torch system,
change PCB3.
033
Precharge
time-out
Auto Gas
Only
Selection console was not
able to charge the lines to
the correct value. This is a warning for a possible gas restriction in the leads.
Verify that there are no restrictions in the plasma and shield
hoses.
042
Low nitrogen
(N2) gas
pressure
Nitrogen gas pressure
under lower limit of
2.07 bar (30 psi) – cutting
0.34 bar (5 psi) – marking
During N2 purge, when
switching between a fuel
gas process and an
oxidizer process.
1.Verify that the nitrogen supply is turned on and inspect gas
supply pressure and volume of gas remaining in supply tanks.
2. Verify that the gas regulator is set to 8.27 bar (120 psi). See
Setting the supply regulators (Installation section).
044
Low plasma
gas pressure
Plasma gas pressure
under lower limit of
0.34 bar (5 psi) – preflow
3.45 bar (50 psi) – cutflow
(cutting)
0.34 bar (5 psi) – cutflow
(marking)
1. Inspect gas supply pressure and volume of gas remaining in
supply tanks.
2. Verify the gas regulator settings on gas console with the
parameters in the cut charts.
3. See Setting the supply regulators (Installation section).
4. Perform gas leak tests (Maintenance section).
