6. DISPLAY & ALARM CONFIGURATION
In addition to loading the BA488CF-F
FOUNDATION™ fieldbus display Device
Description files onto the system host and defining
up to eight fieldbus variables that are to be
displayed, the instrument display and alarms, if
fitted, have to be configured. How much of this
configuration can be done via the fieldbus depends
upon the instrument version and the system host.
Parameters that can not be configured via the
fielldbus, may be set via the four front panel push
buttons
All the display and alarm configuration functions
are contained in an easy to use menu that is
shown in Fig 7. Where necessary the sub-menus
contain on-screen prompts to guide the user
through each adjustment.
When navigating through the configuration menu,
the push button(s) should be held until the required
screen is displayed.

6.2 Accessing the display configuration
menu
Throughout this manual push buttons are shown in
italics e.g. PE▼▲and legends displayed by
the instrument are shown within inverted commas
e.g. 'Enter Access Code'.
Operating the Pand Epush buttons simultaneously
accesses the display configuration menu. If the
BA488CF-F is not protected by an access code the
main menu will be displayed. If an access code
other than the default code 0000 has already been
entered, the BA488CF-F will request that the
access code be entered.
Using the ▼or ▲button set the first digit of the
code which will be flashing. Pressing Pwill transfer
control to the next digit, which should be adjusted in
the same way. When all four digits have been set,
pressing the Ebutton will enter the access code.
If the code is correct the main menu will be
displayed, if the code is incorrect ‘Invalid Code’ will
be displayed.
When entering an access code, timeout will occur
and the instrument will automatically return to the
operating mode ten seconds after a push button
was last operated. In all other menus, timeout
occurs after sixty seconds.
The structure of the display configuration menu is
shown in Fig 7. Navigation is achieved by
highlighting the required function using the ▼and
▲buttons and then operating the Pbutton to
display the selected function sub-menu, from which
a further selection or adjustment may be made.
Operating the Ebutton moves the display back up
one level.
A flashing highlight indicates that an option or
alphanumeric character may be selected using the
▼and ▲buttons and entered using the Ebutton.
If only one entry or adjustment can be made in a
sub-menu, the display will automatically move up
one menu level when the adjustment is entered. If
more than one adjustment can be made in a sub-
menu, the highlight may be moved to the second
variable using the ▼or ▲button after the first
setting has been entered. Operating the Pbutton
allows the second variable to be adjusted.
When multiple numeric or alpha characters are
adjusted e.g. an alarm setpoint or a tag legend, the
adjustment is made one digit at a time using the ▼
and ▲buttons. After the first flashing digit has been
set as required, the flashing highlight can be moved
to the next digit by operating the Pbutton. When all
digits have been set, operating the Ebutton will
enter the setting.
Following completion of the instrument
configuration, the Ebutton should be operated to
step the display back to the main menu. One more
operation of the Ebutton will then return the
BA488CF-F to the operating mode.
