Viewing Menus
Accessing the menus for viewing purposes is accom-
plished by using the UP, DOWN, ENTER, and ESC
(ESCAPE) keys. The direction of available menus is indi-
cated to the user by display of special characters; down
arrow, up arrow, and up and down arrow; on the last col-
umn of the first LCD line. The initial state of the menu
system displays the first item from the main menu, CON-
FIGURATION; this is called the home position. From this
point the user can proceed as follows:
1. Press the UP and DOWN key to view other main menu
items.
2. Press the ENTER key to access the first submenu
from the selected main menu item.
3. Press the ESC key to go back to the home position if
the menu is not already there.
Once the first submenu item from a selected main menu
item is displayed, the user can proceed as follows:
1. Press the UP and DOWN key to view other submenu
items.
2. Press the ENTER key to access the first page menu
from a selected submenu item.
3. Press the ESC (escape) key to go back to the previ-
ously selected main menu item.
Once the first page menu item from a selected submenu
item is displayed, the user can proceed as follows:
1. Press the UP and DOWN key to view other page
menu items.
2. Press the ESC (escape) key to go back to the previ-
ously selected submenu item.
The FXB function tree (Figure 3) illustrates the sublevels
of the FXB Menu System. The first row contains the six
main menu items: Configuration, Basic Parameters,
Advanced Parameters, Meters/Counters, Event
Recorder, and Load Profile. Under each of these main
menu items is a number of submenus demonstrating
what type of information can be obtained or changed at
the next level or page menu.
Editing Parameters
The EDIT key becomes active when a page menu is
being displayed and at least one parameter from the
menu has the write or reset attribute. For example, the
RMS currents are read-only parameters, so the EDIT key
has no effect when they are displayed.
To edit a parameter, proceed as follows:
1. Press the EDIT key. A left arrow character is dis-
played on the last column of the LCD line to indicate
which parameter to select for editing.
2. Press the UP or DOWN key to select which parame-
ter to edit.
3. Press the EDIT key. The left arrow character changes
to a blinking up & down arrow character to indicate
that the parameter can now be edited.
4. Press the UP or DOWN key to select the desired
parameter value. For parameters that have a wide
range of values such as Minimum Trips, a speed
increment/decrement feature has been implemented.
If the UP or DOWN key is held pressed-in for up to
approximately 3 seconds, the parameter value is
updated at a rate of approximately 10 times per sec-
ond. After 3 seconds of continuously pressing either
key, the parameter value is increased or decreased,
respectively, by approximately 5% of its remaining
range and updated at a rate of approximately 10
times per second.
5. Once the desired parameter has been selected,
press the ENTER key to perform the change and then
exit from the edit mode. If the previously selected
parameter is rejected by the control, the message
PARAMETER REJECTED is displayed. Press the
ESC (escape) key to clear the message, then return
to the view mode. For example, the range of valid
minimum trips depend on the CT ratio, so it is possi-
ble to have a minimum trip setting that would be con-
sidered invalid at the time a CT ratio change is
attempted.
When the LCD becomes active, the first parameter to be
edited requires the user to enter the active password.
To enter the password, proceed as follows:
1. Press the EDIT key. The blinking up and down
arrow character is displayed to indicate that the active
PASSWORD can now be entered. Then use the UP
and DOWN key to select an alphanumeric number.
2. Press the ENTER key. This will store the first character
and set up the selection of the next character. Since
the password consists of four characters, select and
enter the second, third, and fourth characters. The
user can only see the character being selected. Other
characters are displayed as asterisks (*).
3. After selecting the fourth character, press the
ENTER key. If the password just entered is the same
as the active password, the LCD returns to the view
mode and the previous sequence for editing parame-
ters can now be followed. If not the same, the message
INVALID PASSWORD is displayed.
4. If the ERROR message is displayed, press the
ESC key to clear it and return to the view mode.
If the user has changed the password but is unable to
remember it, contact your Cooper Power Systems repre-
sentative.
