6.23 Reset configuration to factory defaults:
r5Et dEF
This function returns the BA367NE Counter to the
factory defaults shown in section 6.0. To prevent
accidental use the request must be confirmed by
entering
5urE
before the configuration change will be
executed.
Select
r5Et dEF
from the configuration menu and
press
(
the instrument will display
0000
with the
first digit flashing. To confirm the instruction to reset
all the configuration functions to factory defaults
5urE
must be entered. Using the
&
or
*
button
set the first flashing digit to
5
and press
(
to
transfer control to the second digit which should be
set to
u
. When
5urE
has been entered pressing the
)
button will reset all the configuration functions to
the factory default settings and zero both the total
display and the grand total. While resetting the
BA367NE Counter will display
- - - - - - - -
before
automatically returning to the display mode when the
operation is complete.
6.24 Display overflow
The BA367NE Counter total has a maximum display
range of
-9999999
to
99999999
when shown on the
eight digit upper display. If this range is exceeded
the display will be as shown below with all of the
decimal points flashing:
Underrange
-9 . 9 . 9 . 9 . 9 . 9 . 9
Overrange
9 . 9 . 9 . 9 . 9 . 9 . 9 . 9
When the total is shown on the lower six digit display
the maximum display range is
-99999
to
999999
.
When a total overflow occurs the actual total may be
obtained from the instrument's grand total display
which has sixteen digit - see 2.2.
To prevent future total display overflows occurring
the total scale factor
5CALE . t
and the position of the
decimal point in the total display
dP
should be
reviewed.
7. CONFIGURATION EXAMPLE
A BA367NE Counter is required to display the total
number of strokes that a reciprocating pump makes
in thousands of strokes on the larger upper display
and to show the speed of pumping in strokes per
hour on the lower display. The stroke sensor is a
proximity detector which produces four pulses per
stroke. The total display is only to be resettable by
an external contact, not from the BA367NE Counter
front panel. Similarly the grand total is not to be
resettable from the BA367NE Counter front panel.
To simplify reading the BA367NE display is to be
updated every 3 seconds and to prevent tampering
the instrument configuration menu is to be protected
by security code 1209.
The BA367NE may be configured on-site without
disconnection from the power supply or from the
proximity detector. This example assumes that the
BA367NE initially has default factory configuration.
If after accessing the configuration menu the interval
between operating any front panel push button
exceeds one minute the BA367NE will automatically
return to the display mode and any configuration
changes will not be stored in permanent memory.
When making multiple changes it is therefore
sensible to occasionally return to the display mode
to save the changes that have already been made.
Step 1 Enter the configuration menu
Put the BA367NE Counter in the
configuration mode by simultaneously
pressing the
(
and
)
push buttons .
Assuming a security code has not
already been entered the instrument will
respond by displaying
inPut
which is the
first parameter in the configuration menu.
See Fig 11.
Step 2 Select the type of inputs
With
InPut
displayed; press
(
to reveal
the
inPut . tYPE
submenu and press
(
again to enter the function. Using the
&
or
*
button select
Pr.dEt
, the input
for a 2-wire proximity detector and then
return to the
inPut
prompt in the
configuration menu by pressing
)
twice. A proximity detector requires
energising therefore terminals 3 and 4 of
the BA367NE should be linked together.
