Front-Panel Interface
Pushbuttons
Figure 8.8 , at the end of this section, shows the essential menu and display
structure for the
{SET}
button. It does not show anything below the setting
section (subgroup) level, since this would be too cumbersome.
GLOBAL
This command is roughly equivalent to the SHO G and SET G serial port
commands. When
GLOBAL
is selected, a menu appears for selecting whether to
Set
or
Show
the settings. If
Set
, a password entry screen appears if password
protection is in force.
The next screen is either the
Set GLOBAL
or
Show GLOBAL
display, in which a
message scrolls across the second line, reminding the user to
Press TARGET
RESET for help during set/show routine
. This special use for the
{TARGET
RESET}
pushbutton provides the user with a short description of the setting and
the range of values, should the user not recognize the setting by its Character
string name.
The next menus to appear allow the user to enter a specific section of the
GLOBAL
settings, rather than having to scroll through all
GLOBAL
settings. The
sections are
RELAY SETTINGS
,
BATTERY MONITOR
,
BKRn MONITOR
,
ANALOG
INPUT LABELS
,
SETTING GROUP SE
lection, and
FRONT PANEL
. Use any arrow
key to move to the desired section, then push
{SELECT}
to enter that section.
For example, selecting
RELAY SETTINGS
, causes the first setting
LER=15
to
appear in the second line of the display. If you do not recognize this setting,
push the
{TARGET RESET}
pushbutton, and the following description will scroll
across the first line:
Length of Event Report (15, 30, 60 Cycles)
.
In the
Show
mode, we can only observe the value. The
{SELECT}
pushbutton
acts like a down arrow, to move to the next setting. The up/down arrows
themselves can be used to move within the list of settings.
In the
Set
mode, we can choose to change the value by pushing
{SELECT}
. An
underscore will appear under the first character of the value. If it has discrete
values, like LER, the up/down arrows can be used to scroll through the
available choices. If it is a numerical variable, the digits are changed one at a
time, using the right/left arrows to move to the digit and the up/down arrows to
select the number to insert. When the setting is displayed at the new value,
push
{SELECT} to enter the change.
When the complete list of settings has been shown or set, the display returns to
the level of selection of which section to
Set
or
Show
.
{CANCEL}
can also be
used to move to this level from within the section of settings. {EXIT} , in the
Set
mode, brings the display to a
Save Changes? Y/N
selection point. In the
Show
mode, it returns to the default display.
GROUP
This command is roughly equivalent to the SHO and SET serial port
commands. When
GROUP
is selected, a menu appears for selecting which of the
six setting groups to
Show
or
Set
. Use the right/left arrow keys and {SELECT} to
choose. The next screen asks you if you intend to
Set
or
Show
the settings. If
Set
, a password entry screen appears, if password protection is in force.
The next screen is either the
Set GROUP n
or
Show GROUP n
display ( n = the
group number), in which a message scrolls across the second line, reminding
the user to
Press TARGET RESET for help during set/show routine
. This
special use for the
{TARGET RESET}
pushbutton provides the user with a short
description of the setting and the range of values, should the user not
recognize the setting by its Character string name.
