The manual is normal
Automatic transmission failure | 1.No power supply or one or two phase power supply is needed |
Check all phases of power supply and restore power supply
|
| Water level is too low |
Put water in the sink
|
| The motor burned |
Repair or replace the motor
|
| 1. Line is loose |
Check wiring and tighten connectors
|
| 2. Frequency converter malfunction | Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting. |
| 3 The frequency converter is damaged | Repair or replace |
| 4. Pressure switch damage | Repair or replace |
| 5 The pressure transmitter is damaged | Repair or replace |
| | 6. Switch failure | Repair or replace |
| Pump non - suction pressure gauge pointer to beat violently | Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument | Check pipeline and bottom valve, refill water diversion. Tighten air leakage |
The pump consumes too much power
|
Too much flow, impeller wear
| Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow |
