534 For a minimum of 600 milliseconds, the shield gas
pressure is less than 75% of the setpoint, and the
setpoint is more than 0.

Corrective action
1. Make sure that the consumables are correct for the operator-selected process.
2. Examine gas hoses and fittings for:
□
Damage and kinks that can restrict flow
□
Leaks that can decrease pressure
3. If the hoses and fittings are good, look at the CNC or XPR web interface to identify the shield gas
pressure.
For information about the recommended shield gas pressure by process type, refer to the XPR Cut
Charts Instruction Manual (809830).
4. Send a command to do a preflow test.
Make sure that the pressure is within the correct range for the active process. For information about
how to do this, refer to the instruction manual for your CNC.
5. Send a command to do a cutflow test, and continue with the following steps:
a. Make sure that there is sufficient pressure on P14.
An error occurs only if the value is less than 75% of the setpoint for at least 600 milliseconds.
b. If the pressure is too high or too low, use the optional external shield gas regulator to decrease
or increase the pressure.
c. Examine voltage going to J21.1 and J21.2 for B2 and to J7 for V11.
Refer to Valve states during operation on page 441 to identify if V11 is enabled. Look for
voltage between 5 VDC – 24 VDC.
d. If B2 and V11 do not have the correct voltage, examine the connections between the control
PCB in the TorchConnect console and the valves.
Make sure that the connections are fully engaged. If the connections are fully engaged but the
code continues, replace the control PCB.
6. If you cannot get the recommended pressure, or if pressure is within range but the code continues,
interchange B2 with B1 or B3, or interchange P14 with a different transducer.
