6.1 General
A few seconds after the device is switched on, the initial display appears in the LCD.
Depending on the device version either measured values (four-line display) or a sin-
gle-phase switching diagram of the feeder status (graphic display) is displayed in the
7SA6.
The setting parameters can be entered via the keypad and display on the front of the
device, or by means of a personal computer connected to the front or service interface
of the device utilising the DIGSI
®
4 software package. The level 5 password (individ-
ual parameters) is required.

DeviceFront Select the
MAIN MENU
by pressing the key. Using the key, select
Settings
,
and then press the key to navigate to the
SETTINGS
display (see Figure 6-1).
In the
SETTINGS
display, use the key to select the desired function, and then use
the key to navigate to that function (e.g., use the key to select the
P.System
Data1
function, and then use the key to navigate to the
P.SYSTEM DATA1
dis-
play, as shown in Figure 6-2.
In general, an item number appears in the menu list to the right of each selection. Nav-
igation can be accomplished using the item number in place of the

This feature is particularly helpful in large menus (e.g., setting lists). Based on the ex-
ample above, from the

, the
SETTINGS
display can be reached by press-
ing on the keypad, and then the
P.SYSTEM DATA1
display can be reached by
pressing on the keypad.
