GC315xx and GC400xx Technical Manual 105
The programming is accessible with the controller in any operation state, while parameters
can only be modified, in general, with the controller board in OFF/RESET.
To enter programming mode, use the UP ▲ and DOWN ▼ buttons till the base
PROGRAMMING mode (P.03) screen is displayed.
When in a mode that limits the use of vertical scrolling buttons, it could be necessary to press
one or several times the ESC button (this situation can occur when displaying history logs or
during some operations, such as setting the fuel pump control mode).
Then, press ENTER to access programming
The menu or variable selected before the last exit from programming are automatically
displayed when starting the procedure (the main menu is displayed the first time you access).
This is true if the programming procedure has been previously aborted by changing the
operation mode of the controller board in MAN or AUTO or after maximum time with no
programming operation has elapsed or keeping the ESC button pressed for more than two
seconds.
Press the ENTER n to access the selected (highlighted) sub-menu. Press the ESC to leave
the menu (back to the previous menu or to the base screen if exiting programming in the main
menu).
The forth and the fifth lines show a unique code of the parameter (four decimal digits),
followed by the description in the current language
The sixth line shows the variable value, between brackets, aligned to the right side
“< >”.
For some parameters, on the eighth line, a value is shown, which is in some way
related to the actual parameter value. For example, in the case of the rated generator
power, the rated plant current is shown, derived from the rated generator voltage (P.
0102) and from the parameter itself (rated power, P.0106). Sometimes, this additional
measure can be displayed for showing its absolute value, when the parameter is a
percentage of other values.
Use the ▲ e ▼ buttons to cyclically scroll through the menu to the lower and upper index items
(i.e. pressing the ▲ allows to directly cycle from the first item to the last one and vice versa).
Press the ENTER button to enable the parameter modification procedure (see following
paragraph). Press the ESC button to leave the menu (back to the previous menu).
Current menu name, selected menu item and number of menu items are always displayed in
the second line. Menu items (submenus) are displayed in the following lines. The item selected
is displayed in REVERSE. Use the ▲ e ▼ buttons to cyclically scroll through the menu to the
lower and upper index items (i.e. pressing the ▲ allows to directly cycle from the first item to
the last one).
The name of the current menu (in the example the menu “1-SYSTEM”) is always shown in
the first line, followed by the numeric Id of the selected item and the number of menu items.
The following lines are used to display single parameters. In detail:
