5.1 LED indicators
As shown in Figure 5, there are 3 indicator LED’s
on the front panel of the inverter. These LED’s
indicate Power, Run and Fault. When the system
is energised, the power LED is lit (green),
otherwise it is unlit.
When the system is operating normally, and is
generating power, the run LED is lit (green),
otherwise it remains unlit.
When the system develops a fault, the Fault LED
lights one of two colours to indicate a fault. A Red
LED indicates a category 1 fault; a green LED
indicates a category 2 fault.
When the fault is removed, this LED turns off.
5.2 LCD Panel
The LCD shows two lines of information. By
touching the case of the inverter, the display will
be backlit for a period of 30 seconds.
The display screen can display 3 categories of
information – system initialisation; normal
operation and system operating mode including
the fault categories.
When the system is energised, the LCD module
will start Initialisation. See figure 6 for start
sequence display.
