5.3. Menu 2 – Status / Warning Menu

This menu is displayed when STATUS/WARN/FAULT is selected from MENU 1.
The left hand side of this menu shows the real time status of the rectifier, inverter
and static switch. The right hand side shows the warning or fault conditions. if
any. Therefore, under normal conditions, the LCD display should be exactly as
shown above. When minor abnormal conditions occur, these will be shown under
the title < WARNING >. These will be overridden by a fault message if more
serious abnormal conditions occur, and the title < WARNING > will change to <
FAULT >. For example, if short circuit occurs at the output, this screen will
display the following:

< S T A T U S >

< F A U L T >

R E C T I F I E R = O N

S H O R T C I R C U I T !

I N V E R T E R = O F F
