358 358  The following example uses a current sensor to simulate a water pressure test, the sensor specification is 4-20mA current signal, the range is 16 bar. use the sensor to connect to the AI2 terminal port of the VB.
359 359  Firstly please check the software version of **F7.11**, **F7.11 **is software version, if the **F7.11 **is greater than 2.064, please use A4 parameter group, A4 parameter group is special parameter for constant pressure water supply project.

377 -In the parameter setting of group F9, 20mA is the maximum value of the transducer with a range of 16bar, and F9.01/F9.29/F9.31 are the setting parameters for the water pressure in the VB in percentage. For example when the inverter is required to keep the pressure at 8bar, modify F9.29=50%. F9.01 is the upper limit of water pressure setting, it is recommended to set F9.29=F9.01,of course you can set F9.01=80%,it needs to be greater than or equal to F9.29.
