Inverter Wiring
Special function:
1) Timing control: Set eight pressure reference in specific time period
2) PID control: Constant pressure regulation
3) Control up to 7 different pumps automatically according to pressure feedback, store specific
rated current separately
4) Energy saving function: Stop automatically when flow is smaller
5) Timing switchover function: Prevent pump from rust, balance every pump lifetime
6) Over pressure/under pressure alarm, record the faulty pump and switch the spare pump
automatically.
7) Dormant control
8) Built-in RS 232
9) Liquid level detection and control
Typical application:
Water supply, Air compressor, Central air conditioner, Oil transportation pump, Waste water
treatment, Music Fountain
PID Constant Pressure Water Supply Control
