4.1.3 Turning the display backlight on
The display backlight is normally off. It turns on during the display test at power up.
• To turn on the backlight manually, press any LHMI push button.
The backlight turns on and the panel is ready for further operations.
If the panel has not been used for a predefined timeout period, the backlight is
switched off. The user is logged out from the current user level 30 seconds after the
display backlight has turned off.
The display returns to the default view and all unconfirmed operations such as
parameter editing and breaker selection are cancelled.
Change the backlight timeout period in Main menu/
Configuration/HMI/Backlight timeout.
4.1.4 Selecting local or remote use
The control position of the protection relay can be changed with the R/L button. In

controlled via the LHMI. In remote position, control operations are possible only from
a higher level, that is from a control center.
