Description
The 469 display messages are organized into main menus, pages, and sub-pages. There
are three main menus labeled settings, Actual Values, and Target Messages.
Pressing the
MENU key followed by the MESSAGE T key scrolls through the three main
menu headers, which appear in sequence as follows:
Pressing the
MESSAGE X key or the ENTER key from these main menu pages will display
the corresponding menu page. Use the
MESSAGE T and MESSAGE S keys to scroll
through the page headers.
When the display shows
SETTINGS, pressing the MESSAGE X key or the ENTER key will
display the page headers of programmable parameters (referred to as settings in the
manual). When the display shows
ACTUAL VALUES, pressing the MESSAGE X key or the
ENTER key displays the page headers of measured parameters (referred to as actual
values in the manual). When the display shows
TARGET MESSAGES, pressing the
MESSAGE X key or the ENTER key displays the page headers of event messages or alarm
conditions.
Each page is broken down further into logical sub-pages. The
MESSAGE T and
MESSAGE S keys are used to navigate through the sub-pages. A summary of the settings
and actual values can be found in the chapters 5 and 6, respectively.
The
ENTER key is dual purpose. It is used to enter the sub-pages and to store altered
settings values into memory to complete the change. The
MESSAGE X key can also be
used to enter sub-pages but not to store altered settings.
The
ESCAPE key is also dual purpose. It is used to exit the sub-pages and to cancel a
settings change. The
MESSAGE W key can also be used to exit sub-pages and to cancel
settings changes.
The
VA L U E keys are used to scroll through the possible choices of an enumerated settings.
They also decrement and increment numerical settings. Numerical settings may also be
entered through the numeric keypad.
Pressing the
HELP key displays context-sensitive information about settings such as the
range of values and the method of changing the settings. Help messages will
automatically scroll through all messages currently appropriate.
The
RESET key resets any latched conditions that are not presently active. This includes
resetting latched output relays, latched Trip LEDs, breaker operation failure, and trip coil
failure.
