Functions :- Constant Pressure control by frequency converter
- Quiet and Non Water Hammer operation. Built in PI control function to control the pump in soft start and stop to prevent water hammer; to control the speed increase and decrease gradually to prevent the noise in sudden speed change
- System Stop automatically when no use of water. When the system detect no use of water, motor will reduce the speed in 10%, after 10sec, the system will stop the pump operation
- Dry Running Protection. When the pump running in full speed, but the pressure is still 50% under setting point After 30sec, the system will shut down the power to prevent the damage of pump. Need to reset the system, then the pump can be restarted in 10sec.
- Motor Protection Functions: High / Low voltage; Over current, Overloading; Overheating; phase failure; grounding failure
