The screen gives a summary of the basic GPC parameters:
• voltage on the load (V),
• current in the load (A)
• power on load (KW)
of the three modules.
The screen is displayed:
• with the GPC is switched on (keypad already connect-
ed),
• when connecting the keypad to the GPC (in the ab-
sence of alarms),
• by pressing the HOME button.
5.3.2. Accessing the menu
To access the menu, press the MENU button.
The keypad checks whether a password has been set (con-
figurable via GF_eXpress).
If the password has not been enabled (PASS.C = 0), the
menus are accessed directly.
If the password is enabled (PASS.C > 0), it displays the
screen on which to enter the numeric password (PASS-
WORD = PASS.C) which allows access to the menus, if the
value entered is correct.
02.01 ADDR: 10 - 889

0
Def: 0
If the password entered is incorrect, you return to HOME.
The entered password will remain valid until the GPC-OP is
disconnected from the GPC or the HOME or ALARM button
is pressed.
For instructions on changing your password, see paragraph
“5.3.5. Changing a numerical parameter”.
5.3.3. Browsing the menus
Press the ► key to enter the submenu or parameter. The
same result is obtained by pressing the ENTER key.
Press the ► key twice to return to the main menu.
Press the ▼ and ▲ keys to scroll through the various menu
items.
Each menu item is preceded by a numerical address with
2-digits (1st level menu), 4-digits (2nd level menu) or 6-dig-
its (3rd level menu). The address digits are grouped in twos
and separated by a dot.
