P0.03 is the range of the sensor. Common range is 1MPa, namely 10.0bar.
P0.00 is the pressure value of the pipe network. If P0.00=3.0bar, after the smart
pump drive is started, the pressure of the pipe network keeps constant at 3.0 bar.
General sensor is in current type. The wiring method of SPD is similar to
pressure transmitter, connected to AI terminal as pressure feedback: if voltage
sensor is use, please modify P0.04 to 0. The wiring method of SPD is similar to
transmissible pressure gauge, connected to AI terminal as pressure feedback.
Note: because working voltage of sensor is different, before using, set working
power source of the sensor by P0.05; besides, make sure test result is precise. Set
range of the sensor P0.03 according to sensor parameters.
When feedback value is smaller than or equal to set pressure minus PID start

, and it holds the state in P0.10 set time, PID adjustment
will be restarted. For example, when P0.00=3 ， P0.01=0.3 ， P0.10=5.0, if feedback
value is smaller than or equal to 2.7, and the time is longer than 5s, PID adjustment
will be restarted. Once it is larger than 2.7, the time will recount.
