HMI operation
By using the LCD screen, the operation keys and the function keys, the user can access
functions such as recording, monitoring, relay setting and testing.
Note: The operation of the LCD screen is more or less common in all IED models.
However, the contents of the LCD screen depend upon the IED model.
(i) Screen and LEDs during normal HMI operation
When the IED is operating normally, the green "IN SERVICE" LED is lit. Press any key except
the key CLEAR; and then the backlight of the LCD screen is turned on

LED is
lit.

Note: If another fault occurs during the period of time for which the previous fault pop-
up screen, is displayed, the previous fault information will be overwritten by the
new fault on the pop-up screen. Press the key CANCEL to remove the pop-up
screen for “Latest Fault” to return to the previous screen.

(ii) Main-menu and Sub-menu
➢ Main-menu
If LCD screen is turned off, press any key, except the key CLEAR. “Main-Menu" will
appear on the LCD screen (see the left of Figure 12.2-1). To go to the next level of
hierarchy, press the key ►.
➢ Sub-menu
An example of setting the sub-menu screen is shown in the right of Figure 12.2-1. By
using the key ▼ and the key ▲, the user can move the cursor downward or upward
to view all of the items. By using the keys ◄ ►, the user can return to a previous
level of hierarchy or go to the next level of hierarchy.
➢ Screen structure
The screen is composed of a title area and a data area. The title area is fixed on the
top two lines. The first line displays the screen title. The second line on the left-hand
side displays local time, whereas the right-hand side displays either the current line
number, cursor position number and the maximum page number, or the item number.
For example, the display “2/4” means the current cursor position, which is at the
second item of a maximum of four items.
