Automatic HMI Display Priorities
The REPORT STATUS screen (menu branch 1) provides fast and easy access to the most often used report
and status data. Screens available under this menu heading report RECLOSER status, TARGET status,
ALARM status, and OPERATIONAL status of inputs, outputs, controls, active setting group, and breaker
state. In addition, up to 16 screens from anywhere in the menu system can be selected to be displayed in
a screen scroll list.
If no front panel controls are operated for approximately five minutes, the relay automatically displays the
highest priority REPORT STATUS screen. This keeps frequently viewed data on the displayed screen or
at most, only a couple of keystrokes away. Automatic screen display follows the priority logic described in
Table 4-1.

If the recloser is inactive and no targets or alarms exist, the relay will scroll automatically through a maximum
of 16 user programmable screens. The screen scrolling list is programmed using the SG-SCREEN
command.
Setting the Screen Scroll list
SG-SCREEN Command
Purpose:
Reads or sets the screens displayed in the scrolling screens mode.
Syntax:
SG-SCREEN<x>[=<default screen number>]
Comments: x = sequence in screen scroll list (1 to 16)
default screen number = screen number as displayed in upper-left-hand corner of display
screen. Consult Figures 4-1 through 4-8 for assistance when making or interpreting scrolling
screens settings.
The default scrolling screens are listed below.
SG-SCREEN1 = 4.6
SG-SCREEN2 = 1.5.6
SG-SCREEN3 = 4.3.1
SG-SCREEN4 = 1.1
SG-SCREEN5 = 3.2
SG-SCREEN6 = 3.5
SG-SCREEN7 = 0
SG-SCREEN8 = 0
SG-SCREEN9 = 0
SG-SCREEN10 = 0
SG-SCREEN11 = 0
SG-SCREEN12 = 0
SG-SCREEN13 = 0
SG-SCREEN14 = 0
SG-SCREEN15 = 0
SG-SCREEN16 = 0
Screen scrolling is disabled by a setting of SG-SCREEN = 0. When scrolling is disabled, no targets exist,
and no HMI activity has occurred for five minutes, screen 1.2, TARGETS is displayed.
SG-SCREEN Command Example
Create a scrolling screen list that consists of three-phase current (screen 3.5) and breaker duty (screen
4.3.2).
SG-SCREEN1=3.5
SG-SCREEN2=4.3.2
