Application guide

Typical Application of Constant Pressure Water Supply

AD800 afford application macro for constant-pressure water supply. It can only be enabled in remote mode. For conventional constant pressure water supply applications, the remote pressure gauge is usually used as the feedback source and DI terminal is used for start/stop the motor. Refer Please refer to below step to use the application macro.

●Set parameter P0-03=1 to enable the application macro. When the application macro is enabled, the following parameters will change automatically:

●Press the start button to run directly. If the PID response can not meet the requirements, please adjust the PID parameters P4-07/P4-08.

Description

P0-30=30%

Target Pressure Set

For example, if the pressure gauge is 0~10Mpa, the target pressure corresponding to P0-30=30% is 3Mpa.

P3-04=7V

AI1 maximum input voltage (upper limit voltage of remote pressure gauge)

When the macro is enabled, terminal AI1 is set as pressure feedback source and the upper limit voltage of remote pressure gauge is set as 7V automatically.

A typical wiring set up is shown as below:
