8.3. KEYBOARD
Meanings and functions of panel buttons result from the description implemented in the
APPLICATION .
For typical cases and standard APPLICATIONS , the keyboard is used to navigate through screens
and the protection menu, including the action of previewing and establishing settings. The
keyboard has eight monostable buttons. Each time the button is pressed, a short audible signal
follows (as defined in the
APPLICATION ).

Buttons are marked with arrows: up (

). They strictly
correspond to the structure and rules of access to usable information (menu) associated
with the protection. Using the arrows, the user can navigate to each menu level and
preview the information characteristic for a selected node or possibly initiate a
corresponding action.

The Kas button is used to confirm that the user has acknowledged important alarms on
the LCD screen. Pressing this button may result in a wider range of effects if such
features have been programmed.

The SEL button is used to select by sequence mode of ON and OFF buttons (according to
the current APPLICATION ).

for the first time, the operation is prepared. Another pressing (after no longer than 2 s)
means execution.
In
uREG
