It is a display menu jump from MENU 1 when STATUS/WARN/FAULT is
selected. The left hand side of this menu shows the real time status of the rectifier,
inverter and static switch states. While the right hand side shows the warning or
fault condition if any. Therefore, under normal condition, the LCD display should
be exactly the same as the figure shown above. When minor abnormal condition

WARNING > will change to < FAULT >. For example, short circuit happens at
the output, this screen will display as follows:
