Changing Data Items - Siemens MJ-5 Installation And Operation Manual

3 Viewing and Changing MJ-5 Data Items
The menu you are viewing is always listed at the top of the
screen, pressing the Menu key once will return you to the
top of that menu. Press the Menu key again to return to the
<METER> menu or home position.
Viewing a specific data item with the Menu Selection keys
is a two-step process:
1. View the menu that contains the desired data item by
stepping left and/or right through the menu structure.
Use the ◄ key to move left and the ► key to move
right. Data items are grouped according to function so
you can readily determine which menu contains the
desired data item (see the Menu Structure Quick
Reference in Appendix G for help in locating a
specific data item).
2. View the desired data item by stepping up or down
through the menu until you see the data item name and
its value on the display screen. Use the ▼ key to move
down in the list; use the ▲ key to move up in the list.
Example
Suppose you want to view the regulator Forward Time
Delay set point. This data item is contained in the <REGU-
LATOR> menu:
1. Press the Menu key twice to return to the <METER>
menu.
Press the ► key multiple times to step through several
2.
menus. When <REGULATOR> appears on the
display screen, you are positioned in that menu and
you can view its data items.
Press the ▼ key multiple times to step down through
3.
the various data items in the menu (Fwd Volts, Fwd
BW, and so on) until "Fwd Delay nnnS" appears and
has the indicator arrow => to its left. "nnn" will be the
currently stored value (in seconds) for Forward Time
Delay.

3.4 Changing Data Items

To change data, you must first view it, as described above.
Then press the Change/Save key. The displayed value
flashes to indicate that a Change will be accepted and to
indicate the data that is to be changed. Press the ▲ and ▼
keys to sequence through the acceptable values. When the
desired value is displayed, press the Change/Save key to
complete the change.
The procedure for changing configuration parameters is
slightly different from the procedure for changing
alphanumeric ones. Examples of each type of change
follow:
Changing Configuration Parameters
In some cases, you will be choosing from one of several
alphabetic settings (for example, the <CONFIGURE>
menu asks you to select among three System types: WYE,
DELTA LAG, and DELTA LEAD).
Example
Suppose you want to change the system type from Delta
Lag to Wye. You know (perhaps from checking the menu
Structure Quick Reference Appendix G) that the System
data item is in the <CONFIGURE> menu, so you must
first scroll to that menu.
1. Press the Menu key twice to return the display to
<METER>.
Press the ► key to step through the menus until
2.
<CONFIGURE> is viewed.
Press the ▼ key until Syst: appears and has the
3.
indicator arrow => to the left of it. In this example, the
display screen would indicate that the present setting
is Syst: DELTA LAG.
4. Press the Change/Save key. Syst: is displayed with
DELTA LAG flashing beneath it to indicate that it is
the data to be changed. Note: The underscore in this
section of the manual denotes flashing.
Press the ▼ key to see the next option. DELTA
5.
LEAD appears on the screen.
Press the ▼ key again to see another option. WYE
6.
appears. Since this is the option you want, press the
Change/Save key a second time to complete the
change. Data item list appears with Syst: WYE on the
screen but WYE no longer flashes. This indicates that
the change has been accepted.
7. Alternative to step 6. If you do not want to save the
changes made, press the Cancel/Reset key to exit
change mode without changing the values.
