Setting Column Row Description

IB Magnitude 02 03 Third setting within third column

The first three column headers are common throughout much of the product ranges. However the rows
within each of these column headers may differ according to the product type. Many of the column headers
are the same for all products within the series. However, there is no guarantee that the addresses will be the
same for a particular column header. Therefore you should always refer to the product settings
documentation and not make any assumptions.
2.8 CHANGING THE SETTINGS
1. Starting at the default display, press the Down cursor key to show the first column heading.
2. Use the horizontal cursor keys to select the required column heading.
3. Use the vertical cursor keys to view the setting data in the column.
4. To return to the column header, either press the Up cursor key for a second or so, or press the Clear
key once. It is only possible to move across columns at the column heading level.
5. To return to the default display, press the Up cursor key or the Clear key from any of the column
headings. If you use the auto-repeat function of the Up cursor key, you cannot go straight to the
default display from one of the column cells because the auto-repeat stops at the column heading.
6. To change the value of a setting, go to the relevant cell in the menu, then press the Enter key to
change the cell value. A flashing cursor on the LCD shows that the value can be changed. You may
be prompted for a password first.
7. To change the setting value, press the Up and Down cursor keys. If the setting to be changed is a
binary value or a text string, select the required bit or character to be changed using the Left and Right
cursor keys.
8. Press the Enter key to confirm the new setting value or the Clear key to discard it. The new setting is
automatically discarded if it is not confirmed within 15 seconds.
9. For protection group settings and disturbance recorder settings, the changes must be confirmed
before they are used. When all required changes have been entered, return to the column heading
level and press the Down cursor key. Before returning to the default display, the following prompt
appears.
Update settings?
ENTER or CLEAR
10. Press the Enter key to accept the new settings or press the Clear key to discard the new settings.
Note:
If the menu time-out occurs before the setting changes have been confirmed, the setting values are also discarded.
Control and support settings are updated immediately after they are entered, without the Update settings? prompt.
2.9 DIRECT ACCESS (THE HOTKEY MENU)
It can be quite a long process to configure settings using the HMI panel, especially for settings and
commands that need to be executed quickly or on a regular basis. The IED provides a pair of keys directly
below the LCD display, which can be used to execute specified settings and commands directly.
