PRODUCT SETUP CHAPTER 5: SETTINGS
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.
Example
To clear event records using pushbutton 1, set Settings > Product Setup > Clear Relay Records > Clear Event Records to
FlexLogic operand ON. Then program the pushbutton by setting Settings > Product Setup > User-
PUSHBUTTON 1
Programmable Pushbuttons > Pushbutton 1 Function to "Self-reset." For a graphical front panel, to use a side
pushbutton 9 to 16 to clear the event records, it also needs to be programmed in a single-line diagram.
The figures show user-configurable pushbuttons for the front panels.
