Question 19

Cavitation protection - Pressure Mode

Answer 19

• Pressure falls -> PSG throttles up
• If PSG can’t recover, switches to RPM Limit
• If pressure recovers, returns to Pressure mode
• If does not recover but stays above 45 psi, remains in RPM limit
  - If below 45 but >15 –> “Lo Water” model –> RPM set at 1100, idle after 7 seconds
  - If below 15 psi –> No Water Mode, goes to idle
