6.4 Local User Interface Menu Structure
The diagram in Figure 19 gives a general overview of the standard top- level display menu
structure (when running fi rmware version A001). The Esc push-button is used to toggle be-
tween the Process Mode (PI screens) and the Setup menus, and to return to upper menu level.
In order to move through the menu items, the user must move the joystick UP and DN .
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 fi rst menu item is highlighted and the
joystick is moved UP, the menu “wraps around” and scrolls down to the end of the menu
item’s list. In order to select the desired menu item, the user must press the joystick down
toward instrument front panel (this action is equivalent to the
Enter button). To go back to
upper menu level, the user must press the Esc button.
All process confi guration parameter settings are password-protected. In order to access or
change them, Program Protection (PP) 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 the 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:

Moving the joystick DN to select the Disabled option and then pushing the joystick (ENT) to
save settings will disable program protection.
If the PP password is set to any value more than Zero, the fi rmware will prompt with “Enter
Program Protection Password” (see Figure 12).

The user must enter up to 3 digits for the program protection code, in order to be able to
access password protected menus.
NOTE: By default, the device is shipped from the factory with the Program
Protection (PP) password set to Zero (PP Disabled).
