5.2 Menu

Structure

The diagram on the Figure 5.7 gives a general overview of the standard top-level
display menu structure when running firmware version A001. The ESC pushbutton
is used to toggle between the Process Mode (PI screens) and the Setup menus.

UP and DN buttons must be used to move through the menu items. When the last
item in the menu is reached, the menu “wraps around” and scrolls back to the
beginning of the menu items list. Similarly, when the first menu item is highlight-
ed and the UP button is pressed, the menu “wraps around” and scrolls down to
the end of the menu item’s list.

All process configuration parameter’s settings are password-protected. In order to
access or change them, Program Protection should be disabled. Each time the
device is powered up, the Program Protection is enabled automatically. By default,
the device is shipped from the factory with the Program Protection (PP) password
set to Zero (PP Disabled). If PP password is set to Zero (Disabled), entering a PP
password is not required. A subsequent screen will appear and the Program
Protection menu item will be selected:
