220V~240 Constant Pressure Single Phase Variable Frequency Drive 1AC 0.4KW~4KW
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, and continuously transmits the changed signal to the inverter, and judges the operation and setting by the microcomputer. After the pressure is compared, the controller sends a command to change the frequency. The controller changes the speed of the water pump motor and the number of enabled pumps by changing the frequency, automatically adjusting the peak and valley water consumption, and ensuring the water supply pipe network pressure is constant to meet the user's water demand.
| Function code | Default value | Set value | Description | |
| F1-11 | 1 | I# inverter | 1 | 1# inverter (master), it must connect the pressure sensor. |
| 2# inverter | 2 | 2# inverter (slave / standby master), connect the pressure senor. | ||
| 3# inverter | 3 | 3# and 4# inverters (slave). | ||
| 4# inverter | 4 | Warning: the address of each inverter cannot be the same, otherwise, the system will work abnormally. | ||
| F0-00 | 1 | 2 | Multiple pumps 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. | ||||
| F0-25 | 300Min | Customer set | To set the running time as master pump, when time arrive, it switches to next pump as master. | |
| When set F0-25=0, this pump will only work as slave pump. | ||||
