, and H
2
O diagnostic codes (695 – 697, 700, 701)
1. During test cutflow and test preflow, look at the CNC or XPR web interface to identify the gas
or water inlet pressure in the mixing module inside the gas connect console. Look at:
 The H
2
inlet pressure (P10) for code 695.
 The Ar inlet pressure (P11) for code 696.
 The N
2
inlet pressure (P12) for code 697.
 The H
2
O inlet pressure (P8) for code 701.
2. If you have a Core, VWI, or OptiMix gas connect console, make sure that the gas inlet pressures
inside the gas connect console are acceptable:
3. If you have a VWI or OptiMix gas connect console, make sure that the water inlet pressure is at
least 2.07 bar (40 psi).
4. When gas flow is less than the pressure range, use the regulators to increase the pressure, if
necessary. Do not exceed the recommended pressures.
5. If the pressure remains too low, examine the gas hoses and gas inlet fittings. Look for:
 Damage or kinks that can restrict flow.
 Leaks that can decrease pressure.
WARNING
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before doing troubleshooting or diagnostic work.
All work requiring removal of the plasma power supply outer cover or panels
must be done by a qualified technician.
