1.8.2 Menu navigation and setting browsing
The menu can be browsed using the four arrow keys, following the structure shown in Figure
7. Thus, starting at the default display the

key will display the first column heading. To
select the required column heading use the

and

keys. The setting data contained in
the column can then be viewed by using the

and

keys. It is possible to return to the
column header either by holding the [up arrow symbol] key down or by a single press of the
clear key

.
It is only possible to move across columns at the column heading level. To
return to the default display, press the

key or the clear key

from any of the column
headings. It is not possible to go straight to the default display from within one of the column
cells using the auto-repeat facility of the

key, as the auto-repeat will stop at the column
heading. To move to the default display, the

key must be released and pressed again.
1.8.3 Hotkey menu navigation
The hotkey menu can be browsed using the two keys directly below the LCD. These are
known as direct access keys. The direct access keys perform the function that is displayed
directly above them on the LCD. Thus, to access the hotkey menu from the default display
the direct access key below the “HOTKEY” text must be pressed. Once in the hotkey menu
the
⇐
and
⇒
keys can be used to scroll between the available options and the direct access
keys can be used to control the function currently displayed. If neither the
⇐
or
⇒
keys are
pressed with 20 seconds of entering a hotkey sub menu, the relay will revert to the default
display. The clear key

will also act to return to the default menu from any page of the
hotkey menu. The layout of a typical page of the hotkey menu is described below:
•
The top line shows the contents of the previous and next cells for easy menu navigation
•
The centre line shows the function
•
The bottom line shows the options assigned to the direct access keys
The functions available in the hotkey menu are listed below:
1.8.3.1 Setting group selection
The user can either scroll using <<NXT GRP>> through the available setting groups or
<<SELECT>> the setting group that is currently displayed.
When the SELECT button is pressed a screen confirming the current setting group is
displayed for 2 seconds before the user is prompted with the <<NXT GRP>> or
<<SELECT>> options again. The user can exit the sub menu by using the left and right
arrow keys.
For more information on setting group selection refer to “Changing setting group” section in
the Operation section (P74x/EN OP).
1.8.3.2 Control inputs – user assignable functions
The number of control inputs (user assignable functions – USR ASS) represented in the
hotkey menu is user configurable in the “CTRL I/P CONFIG” column. The chosen inputs can
be SET/RESET using the hotkey menu.
For more information refer to the “Control Inputs” section in the Operation section (P74x/EN
OP).
