Front-Panel Operator Control Pushbuttons
The SEL-751 touchscreen display features eight operator-controlled
pushbuttons, each with two programmable tricolor pushbutton LEDs, for local
control, as shown in Tabl e 8.4. Refer to Front-Panel Operator Control
Pushbuttons on page 8.15 for details on operator control pushbuttons and
LEDs and their programming.
You can use the front-panel operator control pushbuttons to jump to a specific
screen while using them for LOCK/OPEN/CLOSE operations, etc. You can
program the selectable operator pushbutton screen settings under the
Touchscreen settings category in QuickSet and map the button to a specific
screen. For example, PB04, which is used to trip a breaker by default, can be
programmed to jump to a bay screen by mapping the pushbutton touchscreen
setting FPPB04 to Bay Screen 1. When you press PB04, the display jumps to
Bay Screen 1, where you can see a visual confirmation of the TRIP action.
