10.4.3 Access
4/20mA
output sub-menu:
4-20 oP
Access the BA364NG Counter configuration menu as
described in section 6.2. Using the
&
and
*
push
buttons scroll though the menu until
4-20 oP
is
displayed, pressing
(
will then access the 4/20mA
output sub-menu which is shown in Fig 18.
10.4.4 Enable 4/20mA output:
EnbL
This function allows the 4/20mA output to be disabled
or enabled without altering any of the 4/20mA output
parameters. Using the
&
or
*
push button select
EnbL
in the
4-20 oP
sub-menu and press
(
to reveal
the existing setting
on
or
oFF
. The function can be
changed by pressing the
&
or
*
push button
followed by the
)
button to return to
EnbL
prompt.
Note:
When the 4/20mA output is disabled by
selecting
oFF
, the output is a constant
3.5mA irrespective of the instrument display.
10.4.5 Select rate or total source:
4-20tYPE
The 4/20mA output current can represent the
BA364NG Counter’s rate or total display and this
must be defined before any other 4/20mA current
output functions are configured.
Using the
&
or
*
push button select
4-20tYPE
in
the 4/20mA output sub-menu and press
(
to reveal
the existing setting
totAL
or
rAtE
. The function can
be changed by pressing the
&
or
*
push button
followed by the
)
button to return to
4-20tYPE
prompt.
Note:
If the controlling source of the 4/20mA
output is changed i.e. from rate to total, the
4/20mA output will be disabled and the
output will be a constant 3.5mA irrespective
of the instrument display.
The 4/20mA output must always be re-
enabled and reconfigured following the
controlling source being changed.
10.4.6 Display which corresponds to 4mA
output:
4
.
000
The BA364NG Counter display which corresponds to
a 4.000mA output current is defined by this function.
Using the
&
or
*
push button select
4
.
000
in the
4/20mA output sub-menu and press
(
to reveal the
existing rate or total display with one digit flashing.
The required display can be entered using the
&
or
*
push button to adjust the flashing digit and
the
(
button to transfer control to the next digit.
When set as required press
)
to enter the value and
return to the
4
.
000
prompt in the 4/20mA output sub-
menu.
10.4.7 Display which corresponds to 20mA
output:
20.000
The BA364NG Counter display which corresponds
to 20.000mA output current is defined by this
function. Using the
&
or
*
push button select
20
.
000
in the 4/20mA output sub-menu and press
(
. to reveal the existing rate or total display with
one digit flashing. The required display can be
entered using the
&
or
*
push button to adjust
the flashing digit and the
(
button to transfer
control to the next digit. When set as required
press
)
to enter the value and return to the
20
000
prompt in the 4/20mA output sub-menu.
Note:
If the BA364NG Counter and the 4/20mA
current sink output are powered from
separate supplies, the 4/20mA output
current will continue to flow when the
BA364NG Counter supply fails or is
turned off. Powering both from a
common supply eliminates this effect.
