Single-Machine Variable Frequency Drive Pump Controls Intelligent Water Supply
When the water supply automatic control system works, the equipment detects the pressure change of the water supply pipe network when the water consumption changes through the high-sensitivity pressure sensor installed on the water supply pipe network. When the pressure transmitter pressure is maximum, the inverter frequency is the lowest, the pump motor The lowest speed, when the pressure of the pressure transmitter is the smallest, the inverter frequency is the highest, the pump motor speed is the highest, and the frequency of the inverter changes with the change of water consumption.
After the microcomputer judges the calculation and compares it with the set pressure, it sends a command to change the frequency to the controller. The controller changes the speed of the pump motor and the number of enabled pumps by changing the frequency, automatically adjusting the peak and valley water consumption, and ensuring that the water supply pipe network pressure is constant. .

2.Parameters setting
| Function code | Default value | Set value | Description | 
| F0-00 | 1 | 1 | Single pump system | 
| F0-01 | 0.4MPa | Customer set | 1. Please set it correctly based on requested pressure, the unit is MPa, 1MPa=10bar. | 
| 2. Most of the family used systems, the pressure is 0.3~0.4MPa (3~4bar) | |||
| F0-02 | 80% | Customer set | Wake up pressure; it is the percentage of F0-01. | 
| F0-03 | 0 | 0 | It must be set as “0” while use 0~10V remote pressure gauge. | 
| 1 | It must be set as “1” while use 4~20mA pressure transducer. | ||
| F0-04 | 1.6MPa | 1.6MPa | 1. To set the maximum measure range of pressure transducer. | 
| 2. It must be set correctly, otherwise it may cause pressure is inaccurate. |
