6.4.10 Scale numeric display ‘SCALE’
A scaling factor ‘Gain’ and an offset ‘oFFSt’ may
be applied to the fieldbus process variable using
this function, thus allowing the listener to display
the fieldbus process variable in alternative units.
The ‘SCALE’ function may be selected from within
the edit sub-menu by operating the
▼ or ▲ button.
To enter the function press
P
which will display the
‘GAin’ sub-function, pressing
P
again will reveal
the existing gain with one digit flashing. This
flashing digit may be changed by operating the
▼
or ▲ button; when adjusted the
P
button will move
control to the next digit or to the decimal point
which can be positioned using the
▼ or ▲ button.
When ‘GAin’ has been set to the required value
operating the
E
button will enter the selection and
return to the ‘GAin’ prompt in the sub-menu from
where the ‘oFFSt’ function can be selected using
the
▼ or ▲ button.
To enter the ‘oFFSt’ function press
P
which will
reveal the existing offset with one digit flashing.
Again the flashing digit may be changed by
operating the

button will
move control to the next digit or to the decimal
point. When ‘oFFSt’ has been set to the required
value operating the

Three operations of the
E
button will return to the
‘Edit’ function in the main configuration menu.
6.4.11 Access code for listener configuration
menu ‘CodE’
Access to the listener configuration menu may be
protected by a four digit security code which must
be entered to gain access. New instruments are
supplied configured with the default code 0000
which disables this protection and allows
unrestricted access to the configuration menu.
To enter a new access code select ‘CodE’ in the
configuration menu by operating the
▼ or ▲
button. To enter the function press
P
, this will
reveal the current access code with one digit
flashing. The code may be changed using the
▼ or
▲ button to adjust the flashing digit and the
P
button to move control to the next digit. When the
required code has been selected, press
E
to enter
the selection and return to the ‘CodE’ prompt in the
configuration menu. The revised access code will
be activated when the transmitter is returned to the
display mode.
If the access code is lost please contact BEKA
associates.
6.4.12 Change from fieldbus listener to
fieldbus node ‘tYPE’
This function enables the BA444NDF-P to be
conditioned as a fieldbus node or as a fieldbus
listener. To change the function of the instrument
select ‘tYPE’ in the listener configuration menu
using the
▼ or ▲ button and press
P
to enter
which will show that the instrument is configured
as a fieldbus listener. To change to a fieldbus node
press the
▼ or ▲ button which will toggle the
display to ‘nodE’. To prevent accidental changes
this request must be confirmed by operating the
P
button and entering ‘5urE’. The instrument will
display ‘0000’ with the first digit flashing, using the
▼ or ▲ button set the flashing digit to ‘5’ and press
the
P
button to move control to the next digit which
should be set to ‘u’. When the four letters of ‘5urE’
have been entered, operating the
E
button will
result in the instrument restarting in the display
mode as a fieldbus node.
CAUTION
All the instrument’s listener configuration
information will be lost when it is
changed from a fieldbus listener to a
fieldbus node.
6.4.13 Reset the listener to factory defaults
‘rESEt’
The BA444NDF-P listener may be reset to the
factory defaults that are shown below:
Security Code 0000 (disabled)
For each of the eight inputs:
Decimal point XXX.XX

To reset the BA444NDF-P listener select ‘rESEt’ in
the configuration menu by operating the
▼ or ▲
button. To enter the function press
P
, this will
reveal ‘0000’ with the left hand digit flashing. To
prevent accidental use of this function, ‘5urE’ must
be entered to confirm that the instrument is to be
reset.
Using the ▼ or ▲ button set the flashing digit to ‘5’
and press the
P
button to move control to the next
digit which should be set to ‘u’. When the four
letters of ‘5urE’ have been entered operating the
