The LCD panel includes a screen-saver function to increase the service life
of the display. If there is no user activity or operation (key press) for greater
than 1 minute, the display will enter the screen-saving mode to protect the
screen and prolong the service life.
During normal inverter operation, a key press or any warnings or system
faults that may occur will cause the LCD to exit screen-saver mode.
Interpretation for the indicator lights is shown in Table 4-1and function of the
keys is shown in Table 4-2.
