6. CONFIGURATION EXAMPLE
A BA567E-SS 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 BA567E-SS
Counter front panel. Similarly the grand total is not
to be resettable from the BA567E-SS Counter front
panel. To simplify reading the BA567E-SS 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 BA567E-SS may be configured on-site without
disconnection from the power supply or from the
proximity detector. This example assumes that the
BA567E-SS initially has default factory configuration.
If after accessing the configuration menu the interval
between operating any front panel push button
exceeds one minute the BA567E-SS 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 BA567E-SS 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 8.
Step 2 Select the type of inputs
With
InPut
displayed; press
(

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 BA567E-SS should be linked
together.
Step 3 Select display update
To aid reading the display the
BA567E-SS is only to be updated every
3 seconds.
Select
uPdAtE
from the configuration
menu and press
(
. Using the
&
or
*
button select
3
and press
)
to return to
the
uPdAtE
prompt in the configuration
menu.
Step 4 Define function of upper display
In the example the total number of
strokes is required on the larger eight
digit upper display.
Select
dI5P-1
from the configuration
menu and press
(
which will reveal if
the upper display is showing
rAtE
or
totAL
. Using the
&
or
*
button select
totAL
followed by the
)
button to enter
the selection and return to the
configuration menu.
Step 5 Activate lower rate display
A rate display is required so the lower
display must be activated.
Select
di5PLAY . 2
from the main menu
and press
(
to show the existing
setting. Using the
&
or
*
button
select
on
followed by
)
to enter the
selection and return to the configuration
menu.
Step 6 Position of decimal point
In this example the BA567E-SS is
required to display total and rate with no
decimal points.
Select
d.P.
from the configuration menu
and press
(
. The BA567E-SS will
show and identify the total display with all
the digits activated. Using the
&
or
*
button position the decimal point to the
right of the least significant digit i.e. not
visible.
Operating the
(
button will show and
identify the rate display with all the digits
activated, Again using the
&
or
*
button position the decimal point to the
right of the least significant digit i.e. not
visible.
Finally press
)
to return to the
configuration menu.
