System Running Fault and Trouble Shooting

Abnormal Function	Reason	Solution
Can't Sleep	Outlet pipe leakage; Check valve leakage; Pressure tank damage; High environment EMI; Wrong parameter	Check outlet pipe, or to set b0.13; Inspect check valve; Change pressure tank; Transducer adopt shielded wires, shielded layer connect to PE; Ensure b0.10
Full-Frequency Running	Lose pressure feedback; Wrong parameter; Pump under power	Check transducer and wires; Set b0.22=1, take a factory reset
Motor Noise	Motor abnormal; Motor installation is not stable; Low carry-frequency	Check motor; Proper turn up carrier frequency b0.20
