Программа водоснабжения с одним насосом
Advantages of the plan:
▶ Commonly used single pump water supply function
Sleep/Wake up function: Sleep according to frequency, wake up according to pressure
Pipeline overpressure alarm function
PID feedback disconnection protection function
▶ Improve usability
After selecting the water supply macro, configure the state parameters: output frequency, set pressure, feedback pressure, output current, analog feedback AI2 value
Press the shift key to switch the above state parameters
After selecting the water supply macro, rotating the potentiometer can adjust the given pressure and has anti misoperation function
The unit of water supply pressure is kilogram force (bar), which is convenient for customers to use.
Special macro parameters and wiring instructions for constant pressure water supply
The PP-01=30 parameter is initialized as a dedicated macro for constant pressure water supply. The following parameters are default parameters for specialized macros, and necessary adjustments should be made according to the actual situation during use.

When the monitoring parameters are set pressure or feedback pressure, and the pressure setting source is PA-01, pressing the increase/decrease keys on the operation panel will enter PA-0 1 parameter modification mode. The operation and parameter modification modes are the same, and when it exits, it returns to the monitoring state. |
