User-programmable pushbuttons provide an easy and error-free method of entering digital state (on, off) information. The
number depends on the front panel ordered.
• Enhanced horizontal front panel — 16 user-programmable pushbuttons
• Enhanced vertical front panel — 6 user-programmable pushbuttons
• Standard horizontal front panel — 12 user-programmable pushbuttons
• Graphical front panel — 16 user-programmable pushbuttons (eight physical pushbuttons, eight graphical interface
pushbuttons)
The digital state can be entered locally (by directly pressing the front panel pushbutton or optional graphical front panel
interface) or remotely (via FlexLogic operands) into FlexLogic equations, protection elements, and control elements. Typical
applications include breaker control, autorecloser blocking, and setting groups changes. For example, set pushbuttons 1 to
5 to select settings groups 1 to 5, or set pushbutton 1 to clear event records. The user-programmable pushbuttons are
under the control level of password protection.

The L90 is provided with this optional feature, specified as an option at the time of ordering. Using the order
code for your device, see the order codes in chapter 2 for details.
User-programmable pushbuttons require a front panel with that option. If the front panel was ordered separately,
update the EnerVista software under Maintenance > Change Front Panel.
