is the water overfill protection detection time and F21.28 is full water protection exit time, and X 3 terminal is defined as full solar
water detection alarm, and X4 terminal is defined as full solar water detection alarm reset, the warning signal is shown as
"A.Ful".
7) Alarm Recovery Mode: 0: automatic recovery; 1: manual recovery
This option is for low frequency protection, dry protection, over-current protection, minimum power function; you can select
the alarm restoration by F21.26. When you select 0 for automatic recovery, during fault warning displaying, you can also press
the "RESET" button to stop operation; during fault warning displaying, you can press the "RESET" button to manually clear, you
can also press "RESET" button to achieve stop operation.
8) PQ Curve Function
This model provides a self-defined PQ curve for users to set up five groups of PQ corresponding points according to the
pump cases, to achieve real-time traffic speed, daily flow, cumulative flow, generating capacity, cumulative electricity
consumption; of which by default, daily flow and generating capacity are calculated based on 7h in a day.
9) Status Check
When the photovoltaic pump is running, you can check F21.01 to confirm the current operating status.
