6.1 General
A few seconds after the device is switched on, the initial display appears in the LCD.
In the 7SA522 the measured values are displayed.
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.

, and
then press the
key to navigate to
the

dis-
play (see Figure 6-

In the
6(77,1*6
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
36\VWHP
'DWD
function, and then use the key to navigate to the
36<67(0'$7$
display,
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
and keys.
This feature is particularly helpful in large menus (e.g., setting lists). Based on the ex-
ample above, from the
0$,10(18

6(77,1*6
display can be reached by press-
ing on the keypad, and then the
36<67(0'$7$
display can be reached by
pressing on the keypad.

shown in Figure 6-2. The value of the current setting is displayed in the line just below
the setting address number and title. The value may be text (Figure 6-2, setting
)
or numerical (Figure 6-2, setting ).
