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 +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.

374 +F9.31=Lower limit water pressure
375 +
376 +
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. If when the control effect of the inverter is slow or the descent time is too long, try reducing the integration time: F9.06 = 0.5 or 1.0.
