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 after the display
backlight has turned off. The factory default for display timeout is 60 minutes.
The display returns to the default view and all unconfirmed operations, for example
parameter editing and breaker selection are cancelled.
Change the backlight timeout period in Main menu/
Configuration/HMI/LHMI/DisplayTimeout.

Selecting local or remote use

controlled via the LHMI. In remote position, control operations are possible only from
