5. DISPLAY & ALARM CONFIGURATION
In addition to loading the BA688CF-P PROFIBUS
display GSD files onto the system host and
defining up to eight fieldbus variables that are to be
displayed, the instrument address, display and
alarms, if fitted, have to be configured. How
much of this configuration can be performed via
the fieldbus depends upon the system host.
Parameters that can not be configured via the
fieldbus, 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 6. 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.

5.2 Accessing the display configuration
menus
Throughout this manual the four BA688CF-P push
buttons used for configuration are identified
P E
▼
▲ , and legends displayed by the instrument are
shown within inverted commas e.g. 'Enter Access
Code'.
Operating the
P
and
E
push buttons
simultaneously accesses the display configuration
menu. If the BA688CF-P 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 BA688CF-P will
request that the access code be entered.
Using the ▼ or ▲ button adjust the first digit of the
code which will be flashing. Pressing
P
will
transfer control to the next digit, which should be
adjusted in the same way. When all four digits
have been set, pressing the
E
button 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 6. Navigation is achieved by
highlighting the required function using the
▼ and
▲ buttons and then operating the
P
button to
display the selected function sub-menu, from
which a further selection or adjustment may be
made. Operating the
E
button 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
E
button.
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
P
button
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
P
button.
When all digits have been set, operating the
E
button will enter the setting.
Following completion of the instrument
configuration, the
E
button should be operated to
step the display back to the main menu. One more
operation of the
E
button will then return the
BA688CF-P to the operating mode.
