8.4 Source of output pulse:
5ourCE
The output pulse may be derived from:
dirECt-A
Rate Totaliser input-A pulse.
Output is a duplicate of input-A
pulse.
dirECt-b
Rate Totaliser input pulse-b
Output is a duplicate of input-b
pulse.
5CALEd
Composite total
Input A+b which is defined by the
Count
function in the configuration
menu.
A pulse output occurs each time
the least significant digit of the
composite total is incremented.
The frequency of the pulse output
may be be divided and width
defined by functions
diVidE
and
durAtion
which are only available
when
5CALEd
is selected.
Note:
When input A – input b
A:-b
is selected in the Count
function, the scaled pulse output
5CALEd
is not available.
Using the
&
or
*
push button select
5ourCE
in the
pulse output sub-menu and press
(
to reveal the
existing pulse source. The function can be changed
by pressing the
&
or
*
push button followed by
the
)
button to return to
5ourCE
prompt.
8.5 Divide output pulse frequency:
diVidE
When the output pulse is derived from the least
significant digit of the composite total, the output
pulse frequency may be divided by:
1
10
100
1000
10000
Using the
&
or
*
push button select
diVidE
in the
pulse output sub-menu and press
(
to reveal the
existing divisor. The value can be changed by
pressing the
&
or
*
push button to select the
required value followed by the
)
button to return to
diVidE
prompt.
Note:
This function only appears in the pulse
output sub-menu when the output pulse is
derived from the least significant digit of the
composite total display.
8.6 Output pulse width:
durAtion
When the output pulse is derived from the least
significant digit of the composite total, the output
pulse width in milliseconds is defined by this
function. One of 11 pulse widths may be selected:
0.1
0.5
1
2.5
5
10
25
50
100
250
500
Using the
&
or
*
push button select
durAtion
in
the pulse output sub-menu and press
(
to reveal
the existing pulse duration. The value can be
changed by pressing the
&
or
*
push button to
select the required value followed by the
)
button
to return to
durAtion
prompt.
Note:
This function only appears in the pulse
output sub-menu when the output pulse is
derived from the least significant digit of the
composite total display.
8.7 Stored pulses
If the
diVidE
and
durAtion
functions are configured
such that the output pulse frequency with the
specified pulse width can not be output in real time,
the number of pulses will be stored and transmitted
at the maximum possible speed.
When total-A or total-b are reset to zero, any stored
pulses which have yet to be transmitted will be
discarded.
Stored pulses which have yet to be transmitted will
not be retained when the BA384NG Rate Totaliser
power supply is interrupted.
