HMI Home Screen Display
Home Screen is the default HMI display that is displayed at initial power up and after a configurable
internal 30 seconds (default) of HMI keyboard inactivity at each of the nested menus.
The 4-line display shows the mode for each circuit plus user programmable information as shown in the
tables below.
LN2, LN3 and LN4 values are programmed from the appropriate HOME SCREEN LN(number) MEAS
selection in the MONITOR CONFIG display under CONFIGURATION display. Selecting the blank
selection for the LN value leaves that line blank.
