Step 7
Enter the total scale factor
In this example the proximity detectors
produce fifteen pulses per one metre
movement of the cable.
The position
display is required in metres so the total
(position) scale factor
5CALE . t
should be
set to 15.0.
Select
5CALE . t
from the configuration
menu and press
(
to view the current
value with one digit flashing. Use the
&
and
*
buttons to adjust each digit in
turn and the
(
button to transfer control
to the next digit and to the decimal point.
Enter 15.0 and return to the
5CALE . t
prompt in the configuration menu by
pressing
)
.
Step 8
Enter the rate scale factor
In this example the proximity detectors
produce fifteen pulses per one metre
movement of the cable. The rate display
is required in metres per second so the
rate (speed) scale factor
5CALE . r
should
be set to 15.0.
Select
5CALE . r
from the configuration
menu and press
(
to view the current
value with one digit flashing. Use the
&
and
*
buttons to adjust each digit in
turn and the
(
button to transfer control
to the next digit and to the decimal point.
Enter 15.0 and return to the
5CALE . r
prompt in the configuration menu by
pressing
)
.
Step 9
Set the display timebase
In this example the rate display (speed)
is required in metres per second.
Select
t-bA5E
from the configuration
menu and press
(
to reveal the current
setting. Using the
&
or
*
button scroll
through the three options and select
tb-1
. Return to the
t-bA5E
prompt in the
configuration menu by pressing
)
.
Step 10 Adjust the rate display filter
The rate display filter parameters should
be
adjusted
experimentally
after
installation to provide a stable rate
display with an acceptable step response.
During commissioning it is recommended
that initially the second digit of the rate
parameters is set to 0 (step response off)
and the first digit (amount of filtering) is
adjusted to provide acceptable rate
display stability. The second digit should
then be increased until acceptable rate
display stability is once again achieved.
To adjust the filter parameters select
FiLtEr
from the main menu and press
(
to reveal the current setting. The first
digit will be flashing and may be adjusted
using the
&
or
*
button.
The
(
button will transfer control to the
second digit.
When both are set as
required, return to the
FiLtEr
prompt in
the main menu by pressing
)
.
Note:
While adjusting the filter, the rate is
shown on the lower display so that
stability can be assessed.
Step 11 Direction of count
In this application the direction of count
will determine whether a cable movement
is shown as a positive or negative
position and rate. If input A occurs before
input b, a positive display will result when
the BA364G is configured to count up.
Select
uP
or
dn
from the main menu and
press
(
to reveal the existing setting.
Using the
&
or
*
button select
uP
followed by
)
to enter the selection and
return to the configuration menu.
