Set/Show
You can use the SET/SHOW menus to examine or modify relay port settings,
Global settings, active group settings, and date/time. From the front panel you
can change only the settings classes and settings listed in Table 7.10.
NOTE: You cannot use the front-
panel
SET/SHOW menus to change
front-panel settings. To change front-
panel settings, use a communications
port interface and the SET F command
or use the
ACSELERATOR QuickSet
front-panel settings.
Figure 7.33 shows an example of a group setting change. This example shows
how to enter the setting CTRW (Terminal W CT ratio) from the front panel. At
the
MAIN MENU, select the SET/SHOW item and press ENT. The LCD screen
displays the
SET/SHOW screen of Figure 7.33. Use the navigation pushbuttons
to select the relay settings class (
PORT, GROUP, and GLOBAL) or to change the
ACTIVE GROUP or the DATE/TIME. Select the GROUP class.
Next, select the particular instance of the settings class. For the
PORT settings
class, the instances are
PORT 1, PORT 2, PORT 3, PORT F, and PORT 5. For the
GROUP class, the instances are the numbered groups from 1–6 and M, the
breaker monitor (see the
GROUP screen in Figure 7.33). The class GLOBAL, the
setting
ACTIVE GROUP = n (where n is a number from 1 to 6), and the settings
for
DATE/TIME have no settings instance screens. In the GROUP screen, move
the highlight box to
3 and press ENT.
Proceed to selecting the settings category. The
GROUP submenu in Figure 7.33
is an example of settings Group 3 categories. Once you have highlighted the
settings category, pressing ENT causes the relay to display the particular
settings in that category. The
LINE CONFIGURATION screen in Figure 7.33
shows the settings that you can set in the line configuration settings category.
To edit or examine a setting, use the Up Arrow and Down Arrow pushbuttons to
highlight that setting, then press ENT. The relay displays a settings entry screen
with the existing setting value (see the
SET CTRW screen in Figure 7.33). If the
prompt for the selected setting does not fit on the line, the relay scrolls the
setting prompt across the screen.
Enter the setting name using a method similar to the method described in
Relay Elements (Relay Word Bits). Place characters in the element name field
(with the block cursor) using the navigation pushbuttons.
If the data you entered is valid (within settings range checks), the front-panel
display returns to the settings category screen that shows each setting and
corresponding present value (see the
LINE CONFIGURATION screen of
