5.4. Typical Application Functions 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:
Parameter Name
P0-30=30%
Target Pressure Set
AI1 maximum input voltage (upper
P3-04=7V
limit voltage of remote pressure gauge)
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.
A typical wiring set up is shown as below:
Description
For example, if the pressure gauge is 0~10Mpa, the
target pressure corresponding to P0-30=30% is 3Mpa.
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.
