BEKA BA564G, Manual, Page: 26 / 38

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-01
. 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 BA564G is
configured to count up.
Select
uP
or
dn
from the main menu
and press
(
to reveal the existing
setting. Using the
