3.2 Menu Sequence
The listing below gives a general overview of the standard top-level display menu
sequence when running firmware version A002. The ESC pushbutton is used to
toggle between the process mode (PI screens) and the menu.
The listing in Section 3.2 shows the standard display menu sequence and sub-
menus using the UP button to move through the menu items. The first message
displayed the first time the ESC button is pressed after the converter is powered
up is "Prog. Protection ON". Thereafter, pressing the ESC button while the
flow meter is in monitoring mode (PI screens) will display the parameter that was
last exited.
Program Protection may be turned "off" by pressing the ENT button when the Prog.
Protection menu is displayed. The firmware will prompt with "Change Prog Prot”.
Pressing UP or DN button will toggle current protection status. If password is set
to any value more than zero, the firmware will prompt with "Enter Prot Code". User
has to enter up to 3 digits program protection code, in order to be able to access
password protected menus. Once correct password is entered, program protec-
tion id turned off until unit is powered up again.
When the last menu item is reached, the firmware "wraps around" and scrolls to
the first item on the menu once again (see Figure 3.12). The menu items in the first
column are upper-level configuration mode functions. Submenu selections
(shown indented in the second column) only appear if the associated upper level
is selected by pressing the ENT push button. The allowable selections of sub-
menu items which are selected by tabular means are shown in detail in Section 3.3
