3.1 Front Panel Display
The integral front panel keypad and display of the SB Energy-
Comm trip unit provide the user with direct access to device
data and settings. Through custom menus and graphical dis-
plays, the user may view and modify the system configuration
and communication parameters, as well as protective and
metering function settings. Both real-time and accumulated
data are available, in addition to current and voltage wave-
forms. The user may also view information in the trip log asso-
ciated with the five most recent trips.
The large liquid crystal display (LCD) on the front panel shows
menus of commands and graphical information about the sta-
tus of the trip unit and the circuit breaker. It is a 128 x128 pixel
backlit display, which is viewable in many types of lighting. The
LCD displays many types of information about the trip unit and
about the circuit breaker.
