In this point you must enter the nominal consumption of the motor,
increase or decrease the value using the arrow keys and validating
with F2 button.
Note: The nominal consumption is indicated on the name plate of the
motor. You must choose the correct value, for example if you connect
an inverter MT select the value 230 V and for the inverter TT, select
400 V.
Use the arrow keys to enter the maximum pressure scale of the
connected pressure transducer.
This value is indicated on the data plate of the pressure transducer,
and must always be between 4 and 20 mA.
Validate this with F2 button.
Use the arrow keys to enter the pressure at which you want the unit
to work.
You must take great care that this value is always within the working
curve of the pump, and always try to avoid the extremes of the curve,
in other words with flows near 0 or very low pressures.
Validate this with F2 button.
Once you have reached this point, the frequency converter will
program itself to know when it no longer has any demand for flow
and should stop. To do this it will ask for help to understand the
features of the installation to which it is connected.
If at this time it is detected that the pressure of the installation is equal
to or greater than the working pressure, the user will be informed that
it is necessary to open the water supply of the equipment in order to
reduce the pressure below the working pressure.
