Parameters Description
of the external power supply requires the presence of minimum solar radiation that allows the energization of
the equipment.
With the input DI2 configured to 21 when the input is TRUE it means that the external source is supplying the
inverter, and it's expected that the power supply is enou h to run the system in nominal conditions. When the
P0264 = 21
input is FALSE it means that the external source is not connected, and the system is been supplied by the
Solar Panels.
5.2 PRESSURE CONTROLLER
This group of parameters allows the user to configure the conditions of operation of the pressure controller.
The pressure controller should receive the pressure return of the system by connecting a pressure transducer
to the analogic input (AI1) and perform the pump speed control, when the user defined pressure is reached
and the solar radiation conditions allow it.
P0231 – AI1 Signal Function
Adjustable 0 to 7
Range:
Properties: CFG
Access groups via HMI:
Description:
This parameter defines the function of the analogic Input AI1. To enable Read the Pressure, select the
corresponding value.
P0251 – AO1 Signal Function
Adjustable 0 to 23 ->
Range:
Properties: CFG
Access groups via HMI:
Description:
This parameter defines the function of the analogic Output AO1. To enable repeat the AI1 value on the AO1,
select the corresponding value.
P0254 – AO2 Signal Function
Adjustable 0 to 23 ->
Range:
Properties: CFG
Access groups via HMI:
Description:
This parameter defines the function of the analogic Output AO2. To enable repeat the AI2 value on the AO2,
select the corresponding value.
