Front-Panel Menus and Screens
Operate the relay front panel through a sequence of menus that you view on the
front-panel display. The
MAIN MENU is the introductory menu for other front-panel
menus (see Figure 4.5). These additional menus allow you onsite access to
metering, control, and settings for configuring the relay to your specific applica-
tion needs. The following menus and screens are representative of what is typi-
cally found in SEL-400 series relays, but each relay has a slightly different list.
See the relay-specific instruction manual to see what is available in that relay.

Support Screens
The relay displays special screens over the top of the menu or screen that you are
using to control the relay or view data. These screens are the
ADJUST CONTRAST
screen and the
PASSWORD REQUIRED screen.
Contrast
You can adjust the LCD screen contrast to suit your viewing angle and lighting
conditions. To change screen contrast, press and hold the ESC pushbutton for one
second. The relay displays a contrast adjustment box superimposed over the dis-
play.
Figure 4.14 shows the contrast adjustment box with the
MAIN MENU screen in the
background. Pressing the Right Arrow pushbutton increases the contrast. Pressing
the Left Arrow pushbutton decreases the screen contrast. When finished adjusting
the screen contrast, press the ENT pushbutton.
