Operation State; Interface Types - Chint Power CPS SCA20KTL-DO Installation And Operation Manual

5.2 Operation state

Table 5-1 indicates the definitions of LED, i.e. indicates the information of
the inverter's operation state. It indicates that the system is energized and
under DSP control when "POWER" lights up.
"RUN" will light up when the inverter detects that the grid connection
conditions meet the requirements and power is fed into the grid. "RUN" will
blink if the grid is in de-rated running state during the period of feeding power
into the grid.
"GRID" will light up when the grid is normal during the operation of the
inverter. Otherwise, "GRID" will blink until the grid restores to normal.
"FAULT" will blink quickly as a fault (except grid fault) occurs. "FAULT" will
not light out until the fault is eliminated. The light will blink slowly when an
alarm occurs. "FAULT" remains illuminated when an internal fault occurs.
The buzzer will give an alarm if a fault (involving power grid fault) occurs.

5.3 Interface types
