Brief Introduction of Equipment
1. One set of EDS1000 series inverters
2. One pump
3. One set of pressure transmitters (current type is the best choice, 4-20mA, is not easy to decay, and can be used for transmission signal for long distance)
4. Contactor, thermal relay, intermediate relay, button switch, indicator lamp etc.

Parameter Settings
F0.02=1orF0.02=2: terminal run command control.
F3.00=2（Constant pressure water supply is effective）
F3.01=0（The pressure given for digital given）
F3.02=1（Feedback channel selection CCI）
F3.03= The target pressure setting (Set according to the requirements, corresponding to the pressure transmitter and pressure gauge range）
F3.05=20 (When the feedback signal is 4-20mA, need to set this parameter to calibrate the pressure feedback signal)
F3.16=30Hz (The sleep frequency can be adjusted when the feedback pressure reaches the target pressure, after sleep delay time, frequency enters a state of dormancy until deceleration time is decreased to 0.)
F3.17= Recovery pressure threshold (when the inverter in a dormant state, pressure below this threshold value, after wake up delay time)
F3.20=0
F3.21= Pressure gauge or pressure sensor range
F3.26=1 (when this parameter is set to 1, can by monitoring the C-11 (pressure), C-12 (back pressure)
Connection: (see wiring diagram)
