Alert
Low psi-Line B For a minimum of
200 milliseconds, Line B
pressure is less than 75% of
setpoint.
1. Review the diagnostic code history for previous
pressure-related codes. Previous codes can
indicate where to look for flow or pressure
problems.
2. Make sure that the inlet gas pressure for Line A
(P2) or Line B (P1) are in the correct range.
3. If the measurement is too high or too low, use
the regulators to adjust the pressure for the
Line A/Line B gas or F5 gas to the correct
range.
4. Examine the consumables:
• Make sure that the correct consumables are
installed.
• Make sure that there is no damage or excess
wear.
5. Replace incorrect consumables or
consumables that have damage or excess wear.
6. Use the gas volume monitors located near the
pressure transducers to look for gas leaks.
