Transfer control to lower rate display by
operating the

prompt in the main menu.
Step 8
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 ‘SCALE-t’ should
be set to 15.0 (may be entered at 15)
Select ‘SCALE-t’ from the main menu
and press
P
which will show the current
figure with one digit flashing. To
position the decimal point, operate the
P
push-button to move the flashing digit
to the second least significant digit.
Pressing the
Up
and
Down
buttons
simultaneously will then fix the decimal
point in front of the least significant
digit.
Using the
Up
and
Down
buttons to
adjust each digit in turn and the
P
button to transfer control between
digits, enter 15.0 (may be entered as
15). Finally return to the 'SCALE-t'
prompt in the main menu by pressing
E
.
Step 9
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
SCALE-r should be set to 15.0 (may
be entered as 15)
Select ‘SCALE-r’ from the main menu
and press
P
which will show the current
figure with one digit flashing. To
position the decimal point, operate the
P
push-button to move the flashing digit
to the second least significant digit.
Pressing the
Up
and
Down
buttons
simultaneously will then fix the decimal
point in front of the least significant
digit.
Using the
Up
and
Down
buttons to
adjust each digit in turn and the
P
button to transfer control between
digits, enter 15.0 (may be entered as
15). Finally return to the 'SCALE-r'
prompt in the main menu by pressing
E
.
Step 10 Set the display timebase
Select ‘t-bASE’ from the main menu
and press
P
to show the current setting.
In this example the rate display (speed)
is required in metres per second. Using
the
Up
or
Down
button scroll through
the three options and select ‘tb-1’.
Return to the ‘t-bASE’ prompt in the
main menu by pressing
E
.
Step 11 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 recommend
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
P
to reveal the current setting. The first
digit will be flashing and may be
adjusted using the
Up
or
Down
button.
The
P
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
E
.
Note:
While adjusting the filter, the rate is
shown on the lower display so that
stability can be assessed.
