1. DESCRIPTION
This general purpose, single channel pulse input
Counter may be configured to count input pulses
from a wide variety of sensors and to display the
total number in engineering units. A smaller six digit
display may be activated to show the input pulse
rate in engineering units per second, minute or per
hour.
This instruction manual supplements the abbreviated
instruction sheet supplied with each instrument.
2. OPERATION
Fig 1 shows a simplified block diagram of the
BA567E Counter. The instrument can be supplied
with a factory fitted internally powered display
backlight, plus one of the following three factory
fitted accessories:
Dual isolated alarms
or Isolated pulse output
or Isolated 4/20mA output
Fig 1 BA567E block diagram
2.1 Initialisation
Each time power is applied to a BA567E Counter
initialisation is performed. After a short delay the
following display sequence occurs:
All segments of the display are activated
Counter starts functioning, using the
configuration information stored in the
instrument’s permanent memory. Unless
total and grand total displays have been reset
to zero, new pulses will be added to the
existing totals.
2.2 Controls
The BA567E Counter is controlled and configured
via four front panel push buttons. In the display
mode i.e. when the instrument is counting the push
button functions are:

3. SYSTEM DESIGN
Fig 2 illustrates the basic circuit that is used for all
BA567E Counter installations. For simplicity,
connections for the optional alarms, pulse output
and 4/20mA output are shown separately in section
8 of this manual.
Fig 2 Basic BA567E system
When designing a system it is important to
remember that terminals 2, 6 and RS2 are
interconnected within the BA567E See Fig 1.
3.1 Power supply
The BA567E Counter requires 10 to 30V dc supply
between terminal 1 & 2 and consumes:
10mA without optional backlight
plus 6mA when terminals 3 & 4 are linked
plus 22mA for optional backlight
3.2 Pulse input
As shown in Fig 2 the BA567E can count pulses
from a wide variety of sensors in the hazardous
area.
The following table shows the switching thresholds
for the various types of sensor. For reliable
counting the pulse input must fall below the lower
threshold and rise above the upper threshold.
Input sensor
Switching thresholds
Lower Upper
Switch 1001000
Proximity detector 1.2mA 2.1mA
Open collector 2k10k
Magnetic pick-off 0mV 40mV peak
Voltage pulse low 1.0V 3.0V
Voltage pulse high 3.0V 10.0V
3.2.1 Switch contact input
Any switch contact may be directly connected to
pulse input terminals 5 and 6, The BA567E
contains a configurable debounce circuit to prevent
contact bounce being counted. See section 5.6
including details of the maximum counting
frequency.
3.2.2 2-wire proximity detector input
Most NAMUR 2-wire proximity detector may be
directly connected to the BA567E pulse input,
providing the minimum operating voltage of the
proximity detector is less than 7.5V. The BA367E
contain a configurable debounce circuit to prevent
false triggering. Three levels of debounce protection
are independently available. See section 5.6.
3.2.3 Open collector input
Sensors with an open collector output may be
directly connected to Counter input terminals 5 & 6.
Polarity of the sensor output should be observed.
The BA567E contains a configurable debounce
circuit to prevent false triggering. Three levels of de-
bounce protection are independently available. See
section 5.6.
3.2.4 Magnetic pick-off input
Sensors incorporating a magnetic pick-off will have a
low level voltage output unless the sensor
incorporates an amplifier. CoiL in the BA567E input
configuration menu is a low level voltage pulse input
intended for use with a magnetic pick-off. The
Counter contains a configurable debounce circuit to
prevent false triggering of the instrument. See
section 5.6.
3.2.5 Voltage pulse input
Two voltage pulse input ranges are selectable in the
BA567E Counter configuration menu, VoLt5 L and
VoLt5 H as shown in section 3.2. The Counter
contains a configurable debounce circuit to prevent
false triggering of the instrument. Three levels of de-
bounce protection are independently available. See
section 5.6.
3.3 Remote reset
The Counter's total display may be remotely reset to
zero by connecting terminals RS1 and RS2 together
for more than one second. Permanent
interconnection inhibits counting.
Note: The BA367E may also be configured to
reset the total display to zero by operating
the &and *push buttons simultaneously
for more than two seconds in the totalising
mode i.e. when the instrument is displaying
flow. See 5.19

4. INSTALLATION
4.1 Location
The BA567E Counter has a robust glass reinforced
Noryl enclosure with a toughened glass window.
The front of the instrument has IP66 ingress
protection and a gasket seals the joint between the
instrument enclosure and the panel. The rear of the
instrument has IP20 ingress protection.
The BA567E may be installed in any panel providing
that the operating temperature is between -40°C and
+70°C. At temperatures below -20°C the instrument
will continue to count but the display digits will
change more slowly and the contrast will be
reduced.
Figs 3 shows the overall dimensions together with
the recommended panel cut-out dimensions. To
achieve an IP66 seal between the instrument
enclosure and the instrument panel, the smaller cut-
out dimensions should be used.
4.2 EMC
The BA567E Counter complies with the
requirements of the European EMC Directive
2014/30/EU. For specified immunity all wiring
should be in screened twisted pairs, with the screens
earthed at one point.
Recommended panel cut-out

4.3 Installation Procedure
a. Cut the specified aperture in the panel. To
achieve an IP66 seal between the instrument
enclosure and the instrument panel the
aperture must have the tighter tolerances
specified in Fig 3.
b. Slide the gasket over the body of the BA567E
Counter before inserting the instrument into
the panel aperture.
c. Firstly ensure that both the panel mounting
clamps are closed by turning the knurled
screws fully anti clockwise until the two pips in
the clamp foot align with holes in the clamp
body.
d. Place a clamp in the recess on each side of
the Counter, pulling gently to slide it onto the
dovetail as shown in Fig 4. Push the knurled
screw slightly forward to engage the thread
and tighten by turning clockwise until it is just
finger tight. When both clamps are fitted
ensure that the gasket behind the front panel
bezel is correctly positioned before fully
tightening the clamps to secure the instrument.
The maximum recommended clamp tightening
torque is 22cNm (1.95 lbf in) which is
approximately equivalent to finger-tight plus
one half turn. Do not over tighten.
e. Connect the panel wiring to the rear terminal
block(s) as shown in Figs 3. To simplify
installation, the terminals are removable so
that the panel wiring can be completed before
the instrument is installed. To prevent vibration
damage ensure panel wiring is supported.
Fig 4 Fitting panel mounting clamps
4.4 Scale card
The Counter’s units of measurement are shown on a
printed scale card in a window at the right hand side
of the display. The scale card is mounted on a
flexible strip that is inserted into a slot at the rear of
the instrument as shown in Fig 5. Thus the scale
card can easily be changed without removing the
Counter from the panel or opening the instrument
enclosure.
New BA567E Counters are supplied with a printed
scale card showing the requested units of
measurement, if this information is not supplied
when the instrument is ordered a blank card will be
fitted.
A pack of self-adhesive scale cards printed with
common units is available as an accessory from
BEKA associates. Custom printed scale cards can
also be supplied.
To change a scale card, unclip the tapered end of
the flexible strip at the rear of the instrument by
gently pushing it upwards and pulling it out of the
enclosure. Peel the existing scale card from the
flexible strip and replace it with a new printed card,
which should be aligned as shown below. Do not fit
a new scale card on top of an existing card.
Install the new scale card by gently pushing the
flexible strip into the slot at the rear of the Counter,
when it reaches the internal end-stop secure it by
pushing the end of the flexible strip downwards so
that the tapered section is held by the rear panel.
Align the self-adhesive printed
scale card onto the flexible strip
and insert the strip into the Counter
as shown below.

5.0 CONFIGURATION & CALIBRATION
The BA567E Counter is configured and calibrated
via four front panel push buttons. All the
configuration functions are contained in an easy to
use intuitive menu that is shown diagrammatically in
Fig 7.
Each menu function is summarised in section 5.3 of
this manual and each summary includes a reference
to more detailed information.
When factory fitted optional dual alarms, pulse
output or a 4/20mA output are included, additional
functions appear in the configuration menu which
are described separately in section 8.
All new BA567E Counters are supplied calibrated as
requested at the time of ordering. If calibration is not
requested, Counters will have default configuration
as shown in the following table, but can easily be re-
configured on-site.

Note: While the instrument is being configured
counting continues so that any input pulses
occurring during this time are recorded.
5.1 Configuration structure
Fig 6 shows the calibration structure of the BA567E
Counter. The pulse input is passed to the 5CALE.r
and 5CALE.t functions allowing the independent rate
and total displays to have different engineering units.
5CALE.t is a dividing factor that converts the input
pulses into the required total display in engineering
units. e.g. if the input is two pulses per pump stroke
and it is required to display the total number of pump
strokes in thousands of strokes, 5CALE.t should be
set to 2000.
5CALE.r is a dividing factor that converts the input
pulses into a rate display with the required
engineering units. e.g. if the input is two pulses per
pump stroke and it is required to display the pump
stroke rate, 5CALE.r should be set to 2.0.
The timebase t-bA5E is a multiplying factor that
determines if the instrument displays pulse rate per
second, per minute or per hour.
The BA567E uses ‘real’ decimal points. Moving the
position of a decimal point in a scale factor will affect
the instrument calibration.
Fig 6 Calibration structure

5.2 Accessing configuration functions
Throughout this manual the instrument front panel
push buttons are shown as &, *, (and )and
legends displayed by the instrument are shown in a
seven segment font as displayed by the Counter
e.g. FiLtEr and 5CALE .r.
Access to the configuration menu is obtained by
operating the (and )push buttons
simultaneously. If the instrument is not protected by
a security code the first parameter inPut will be
displayed. If a security code other than the default
code 0000 has already been entered, the instrument
will display CodE. Press (to clear this prompt and
enter the security code for the instrument using the
&or *push button to adjust the flashing digit,
and the (push button to transfer control to the
next digit. If the correct code has been entered
pressing )will cause the first parameter inPut to
be displayed. If an incorrect code is entered, or a
push button is not operated within ten seconds, the
instrument will automatically return to the display
mode.
All configuration functions and prompts are shown
on the upper eight digit display.
Once within the configuration menu the required
function can be selected by scrolling through the
menu using the &and *push buttons. The
configuration menu is shown diagrammatically in
Fig 7.
When returning to the display mode following
reconfiguration, the BA567E Counter will display
dAtA followed by 5AVE while the new information is
stored in permanent memory.
If after accessing the configuration menu the interval
between operating any front panel push button
exceeds one minute, the BA567E will automatically
return to the display mode and any configuration
changes will not be stored in permanent memory.
When making changes to multiple configuration
functions, it is therefore sensible to occasionally
return to the display mode to save the changes that
have already been made.
5.3 Summary of configuration functions
This section summarises all the configuration
functions. When read in conjunction with Fig 10 it
provides a quick aid for configuring the Counter. If

5.4 Input: inPut
The Input function contains two sub-functions
inP .tYPE and dEbounCE that define the type of input
and the amount of input noise rejection.
5.5 Input type: inP.tYPE
inP .tYPE is a sub-menu in the inPut function which
defines the type of input sensor or input pulse that
the instrument will count. To check or change the
type of input, select inPut in the configuration menu
and press (which will reveal the inP.tYPE prompt,
pressing (again will show the existing Input
setting. If set as required press )twice to return to
the configuration menu, or repeatedly press the &
or *button until the required type of input is
displayed and then press )twice to return to the
configuration menu.

VoLt5 L Voltage pulse low 113V
VoLt5 H Voltage pulse high1310V
CoiL Magnetic pick-off 0 40mV
Pr .dEt Proximity detector 21.2 2.1mA
ContACt Switch contact 2100 1000
Notes:
1. Maximum voltage input +30V.
2. For sensors connected to the input that
require energising i.e. proximity detectors,
switch contacts or open collector sensors,
terminals 3 & 4 of the BA567E should be
linked together.
3. To count correctly, the input pulse must fall
below the lower switching threshold and rise
above the higher switching threshold.
4. See section 5.6 for maximum counting
frequency.
5.6 Input debounce: dEbouncE
dEbouncE is an adjustable sub-menu in the inPut
function which prevents the input miscounting when
the input pulse has noisy edges, such as those
resulting from a mechanical contact closing and
bouncing.
Three levels of protection may be selected. The
amount of debounce applied depends upon the type
of Counter input that has been selected in the
inP .tYPE function.
Select inPut in the configuration menu and press
(which will reveal the inP .tYPE prompt, press the
&or *button to select dEbouncE followed by (
to reveal the existing setting. Pressing the &or *
button will scroll through the three levels. When the
required level has been selected, pressing )twice
will enter the selection and return the display to the
configuration menu.
The following table shows the minimum time that the
input pulse must be continuously above the upper
input switching threshold and continuously below the
lower switching threshold to ensure that the Counter
processes the input pulse. Input switching
thresholds are shown in section 4.1.2.

5.8 Display update interval: uPdAtE
If either the rate or the total display is likely to
change rapidly, a longer interval between display
updates may simplify reading. This function allows
one of six different display intervals between 0.5 and
5 seconds to be selected. The selected display
update interval does not affect the update time of
any other instrument function.
To adjust the update interval select uPdAtE from the
configuration menu and press (to reveal the
current update interval. Pressing the &or *
button will scroll through the six times. When the
required interval has been selected press )to
enter the selection and return to the configuration
menu.
5.9 Upper display: di5P-1
Usually the total count is shown on the larger upper
eight digit display, but this function reverses the
display locations allowing rate to be shown on the
larger upper display and total on the smaller lower
display.
To check the setting for the display, select dI5P-1
from the configuration menu and press (which will
reveal if the display is showing rAtE or totAL. The
setting can be changed by pressing the &or *

This function turns the lower display on or off.
When turned off, the BA567E will only have one
eight digit display which may be configured in the
di5P-1 function to show the total count or rate.
To check the setting for the lower display, select
di5P-2 from the configuration menu and press
(that will reveal if the lower display is on or oFF.
The setting may be changed by pressing the &or
*button followed by the )button to enter the
selection and return to the configuration menu.
5.11 Position of the decimal points: dP
The upper and lower displays have eight and six
digits respectively. This function enables the
position of the decimal point in both displays to be
independently positioned as shown below.
Upper display
Total 000.0.0.0.0.01 of 5 positions or absent
Rate 00.0.0.0.01 of 4 positions or absent
Lower display
Total 0.0.0.0.0.01 of 5 positions or absent
Rate 00.0.0.0.01 of 4 positions or absent
To adjust the position of the decimal points select dP
from the configuration menu and press (. The
upper display defined as the rate or total display by
function di5P-1 (section 5.9) will be activated and
identified by the display annunciator as Rate or
Total. The decimal point, which may be positioned
as shown in the table above, is moved by operating
the &or *push button. The &button moves
the position of the decimal point to the left and the
*button moves the decimal point position to the
right.
When the decimal point in the upper display has
been positioned pressing the (button will transfer
control to the lower display variable, but it will be
shown and annunciated on the larger upper display.
The position of the decimal point may be positioned
in the same way by operating the &and *push
buttons. When both decimal points are positioned
as required, enter the settings and return to the
configuration menu by operating the )button.

5.12 Total scale factor: 5CALE .t
5CALE .T is a dividing factor adjustable between
0.0001 and 99999 that enables the total to be
displayed in engineering units. e.g. if one input
pulse represents 1 centimetre of dispensed cable
and the total display is required in metres, 5CALE .t
should be set to 100.0 which is the number of
centimetres in a metre. If a display of the total
number of input pulses is required, 5CALE .tshould
be set to 1.0. The total display is independent of the
rate display.
To check or change the total scale factor select
5CALE .tfrom the configuration menu and press (
which will reveal the existing value with one digit
flashing. The value of the flashing digit may be
changed by pressing the &or *button. When
this digit has been adjusted as required, pressing (
will transfer control to the next digit. When all the
digits have been adjusted pressing (will transfer
control to the decimal point that may be positioned
between any of the digits, or may be omitted by
moving it to the right of the least significant digit.
When the total scale factor has been entered, press
(to return to the 5CALE .T prompt in the
configuration menu.
Note:
Adjustment of 5cale .twill disable the
following ouputs which must be re-enabled
after the adjustment is complete:
Optional Pulse output
Optional Alarm outputs
Optional 4/20mA output
5.13 Rate scale factor: 5CALE .r
5CALE .ris a dividing factor adjustable between
0.0001 and 99999 that enables the rate display to be
in engineering units. e.g. if one input pulse
represents 2 pump strokes and the rate display is
required in pump strokes, 5CALE .rshould be set to
2.0. If just the rate of input pulses is required,
5CALE .rshould be set to 1.0. The rate display is
independent of the total display.
The units of the rate display are counts per unit of
time. The unit of time is the timebase of the
instrument which is determined by t-bA5E
described in section 5.14.
To check or change the rate scale factor select
5CALE .rfrom the configuration menu and press (
which will reveal the existing value with one digit
flashing. The value of the flashing digit may be
adjusted by pressing the &or *button.
When this digit has been adjusted as required,
pressing (will transfer control to the next digit.
When all the digits have been adjusted pressing
(will transfer control to the decimal point that may
be positioned between any of the digits, or may be
omitted by moving it to the right of the least
significant digit. When the required rate scale factor
has been entered, press )to return to the 5CALE .r
prompt in the configuration menu.
Note:
Adjustment of 5cale .R will disable the
following outputs which must be re-enabled
after the adjustment is complete:
Optional Pulse output
Optional Alarm outputs
Optional 4/20mA output
5.14 Timebase: t-bA5E
The timebase multiplies the rate display by 1, 60 or
3,600 depending upon whether the BA567E Counter
is required to display rate per second, per minute or
per hour. See Fig 6.
To check or change the timebase, select t-bA5E
from the configuration menu and press (which will
reveal the current setting. Pressing the &or *
button will scroll through the three options:
tb-1 for pulses / second
tb-60 for pulses / minute
tb-3600 for pulses / hour
When the required multiplier is displayed press )
to return to the t-bA5E prompt in the configuration
menu.
5.15 Display filter: FiLtEr
The digital display filter has two independent
adjustable parameters enabling the rate display
response to be tailored for optimum performance.
The filter parameters are controlled by a two digit
number. The first digit defines the amount of filtering
applied to the display as shown below.
First digit Filter time constant
Seconds
0X 0
1X 1.3
2X 4.3
3X 6.5
4X 8.7
5X 11.3
6X 15.7
7X 20.9
8X 25.2
9X 31.5
16

The second digit defines the deviation from the
displayed rate at which the filter will be overridden
and the rate display will move rapidly to the new
value.
Second
digit
Magnitude of step
change which will
produce a rapid
response
X0 Off
X1 1%
X2 2%
X3 4%
X4 8%
X5 12%
X6 16%
X7 24%
X8 32%
X9 64%
By careful adjustment of the two parameters a stable
display with an acceptable input step response can
be obtained for most applications.
During commissioning it is recommend that initially
the second digit is set to 0 (off) and the first digit is
adjusted to provide acceptable rate display stability.
The second digit should then be increased until the
selected step size is greater than the noise on the
display signal, at which setting the rate display will
become stable. These will be the optimum filter
parameters for acceptable rate display stability and a
fast response to a large rate signal change.
To check or change the filter select FiLtEr in the
configuration menu and press (which will reveal
the current settings with the first digit flashing.
Pressing the &or *button will adjust the flashing
digit and (will transfer control to the second digit.
While making adjustments the filtered rate display is
shown on the lower display so that stability can be
assessed while adjustments are being made. When
set as required, press the )button to enter the
revised parameters and return to the FiLtEr prompt
in the configuration menu.
5.16 Direction of count: uP or dn
This function defines whether input pulses increment
or decrement the total display. i.e. whether the
BA567E is an up-counter or a down-counter.
When configured as a down-counter with a non-zero
number entered for the reset value CLr VAL, the
BA567E will count down from the reset value to
zero.
To check or change the count direction select
uP or dn from the configuration menu and press
(which will reveal the present setting. uP
indicates that the instrument is an up-counter and dn
that it is a down counter. Pressing the &or *
buttons will toggle the instrument between the two
settings. When set as required, press the )button
to enter the setting and return to the configuration
menu.
5.17 Reset value: CLr VAL
This function defines the value to which the total
display is reset when the local or remote reset are
operated. This allows the BA567E to be used as a
preset down-counter.
When the instrument is used as an up-counter,
Clr VAL is normally set to zero.
To check or change the reset value select CLr VAL
from the configuration menu and press (which will
reveal the current setting with one digit flashing. The
flashing digit may be adjusted by pressing the &or
*button. When this digit is correct, pressing
(will transfer control to the next digit.
When all the digits have been adjusted press the )
button to enter the revised number and return to the
configuration menu.
5.18 Local reset: LoC CLr
The Local reset function contains two sub-functions
Clr tot and Clr Gtot which when enabled allow the
total display and grand total to be reset via the
instrument front panel push buttons while the
BA567E Counter is in the display mode i.e. counting.

The total display may also be remotely reset
to the reset value by connecting terminals
RS1 and RS2 together for more than one
second. See sections 3.3 of this manual.
5.20 Local grand total reset: Clr Gtot
The grand total is a separate sixteen digit counter
which is incremented or decremented in parallel with
the total display, but is not reset when the total
display is reset. The grand total may be viewed in
the display mode in two eight digit sections as
described in section 2.2 of this manual.
Clr Gtot is a sub-menu in the LoC CLr function

the second digit which should be set to u. When
5urE has been entered pressing the )button will
reset the grand total which will be confirmed by a
brief display of Gt Clrd, the instrument will
automatically return to the Clr Gt prompt in the
configuration menu.
Note:
Once reset, the grand total can not be
recovered.
5.22 Security code: CodE
Access to the instrument configuration menu may be
protected by a four digit security code which must be
entered to gain access. New instruments are
configured with the default security code 0000 which
allows unrestricted access to all configuration
functions.
To enter a new security code select CodE from the

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 5and 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
BA567E Counter will display - - - - - - - - before
automatically returning to the display mode when the
operation is complete.
5.24 Display overflow
The BA567E 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 .tand the position of the
decimal point in the total display dP should be
reviewed.
6. CONFIGURATION EXAMPLE
A BA567E 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 Counter
front panel. Similarly the grand total is not to be
resettable from the BA567E Counter front panel. To
simplify reading the BA567E 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 may be configured on-site without
disconnection from the power supply or from the
proximity detector. This example assumes that the
BA567E 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 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 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 7
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 BA567E should be linked together.
19

Step 3 Select display update
To aid reading the display the BA567E is
only to be updated every 3 seconds.
Select uPdAtE from the configuration
menu and press (. Using the &or *
button select 3and 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 is required
to display total and rate with no decimal
points.
Select d.P. from the configuration menu
and press (. The BA567E 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.
Step 7 Enter the total scale factor
In this example the proximity detector
produce four pulses per pump stroke.
The BA567E is required to display
thousands of pump strokes therefore the
total scale factor 5CALE.t should be set to
(4 x 1000) = 4000.
Select 5CALE.t from the configuration
menu and press (to view the current
value with one digit flashing. Use the
&or *button to adjust the flashing
digit and the (button to transfer control
to the next digit and to the decimal point.
Enter 4000.0 and return to the 5CALE.t
prompt in the configuration menu by
pressing ).
Step 8 Enter the rate scale factor
The proximity detector produces four
pulses per pump stroke and the rate
display is required in strokes per hour,
therefore the rate scale factor 5CALE.r
should be set to 4.0.
Select 5CALE.r from the configuration
menu and press (to view the current
value with one digit flashing. Use the &
or *button to adjust the flashing digit
and the (button to transfer control to
the next digit and to the decimal point.
Enter 4.0 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 is
required in pump strokes per hour.
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-3600. Return to the t-bASE prompt in
the configuration menu by pressing ).
