1. DESCRIPTION
The BA564G is a general purpose, field mounting two
input Counter which can accept pulses on one or both
inputs. The Counter may be configured to show total
and rate for one of the following in engineering units:
Input A + Input b
Input A -Input b
Input A count direction controlled by Input b
Quadrature decoder
(Input A and Input b electrically 90oapart)
A smaller six digit display may be activated to show
the composite pulse rate in engineering units per
second, minute or per hour.
In addition to counting applications, the BA564G can
display the position, direction of movement and speed
of a shaft or cable using the instruments quadrature
decoder.
The optically-isolated pulse output may be configured
to synchronously retransmit either of the two pulse
inputs or a scaled output when the least significant
digit of the total display is incremented.
This instruction manual supplements the abbreviated
instruction sheet supplied with each instrument.
2. OPERATION
Fig 1 shows a simplified block diagram of the
BA564G Counter. The instrument has two inputs,
A and b, which can be individually configured to
accept pulses from most types of sensor. The
BA564G can display the total number of pulses
received from each input, or their sum or
difference, together with associated rates on a
separate display.
Fig 1 BA564G block diagram
The BA564G can be supplied with any of the
following factory fitted accessories:
Internally powered display backlight
Dual isolated alarms
Isolated 4/20mA output

2.1 Initialisation
Each time power is applied to a BA564G 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, new
pulses will be added to the existing totals.
2.2 Controls
The BA564G 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:
Push Button Functions

3. SYSTEM DESIGN
Fig 2 illustrates the basic circuit that is used for all
BA584G installations. For simplicity, the pulse output
is described sparately in section 6 and the optional
alarms and 4/20mA output are described in section 9
of this manual.
Fig 2 Basic BA564G System
When designing a system using a BA564G Counter, it
is important to remember that terminals 2, 6, 10 and
RS2 are interconnected within the instrument. See
Fig 1.
3.1 Power supply
The BA564G Counter requires a minimum of 10V
between terminal 1 & 2 and consumes:
10mA without optional backlight
plus 6mA when terminals 3 & 4 are linked
plus 6mA when terminals 7 & 8 are linked
plus 16mA with optional backlight
3.2 Pulse inputs
The BA564G can display the total number of
pulses received and their rate from a wide variety
of pulse output sensors connected to either input.
When designing a system it is important to
remember that terminals 2, 6, 10 and RS2 of the
BA564G Counter are internally connected together.
3.2.1 Input switching thresholds
For reliable operation the Counter pulse inputs
must fall below the lower threshold and rise above
the upper thresholds shown in the following table.
Input transducer
Switching thresholds
Lower Upper
Open collector 2k10k
Voltage pulse low 1.0V 3.0V
Voltage pulse high 3.0V 10.0V
Magnetic pick-off 0mV 40mV peak
Proximity detector 1.2mA 2.1mA
Switch 1001000
Switch contact, proximity detector and open
collector sensors require energising to determine
their state which is achieved by linking Counter
terminals 3 and 4 for input A and terminals 7 and 8
for input b.
3.2.2 Switch contact input
Any switch contact may be directly connected to
pulse input terminals 5 and 6 and to terminals 7
and 8. The BA564G contains a configurable
debounce circuit to prevent contact bounce being
counted. See sections 5.6 and 5.9.
3.2.3 2-wire Proximity detector
Most NAMUR 2-wire proximity detectors may be
directly connected to a BA564G input, providing
the minimum operating voltage of the proximity
detector is less than 7.5V. The BA564G contains
a configurable de-bounce circuit to prevent false
triggering. Three levels of debounce protection are
independently available for each input. See
sections 5.6 and 5.9.
3.2.4 Open collector input
Sensors with an open collector output to input
terminals 5 & 6 or to 7 & 8. Input polarity should
be onserved The BA564G contains a configurable
debounce circuit to prevent false triggering. See
sections 5.6 and 5.9.
6

3.2.5 Magnetic pick-off input
Sensors incorporating a magnetic pick-off will usually
have a low level ac voltage output which a BA564G
Counter can sense when configured for a CoiL input.
The BA564G contains a configurable debounce circuit
to prevent false triggering. See sections 5.6 and 5.9.
3.2.6 Voltage pulse input
Two voltage pulse input ranges are selectable in the
BA564G Counters configuration menu, VoLt5 L and
VoLt5 H. The BA564G contains a configurable
debounce circuit to prevent false triggering. See
sections 5.6 and 5.9.
3.3 Remote reset
The BA564G Counter's total display may be
remotely reset by connecting terminals RS1 and
RS2 together. Permanent interconnection inhibits
counting. Remote resetting may be accomplished
by any switch contact.
The BA564G total display may also be reset when
the &and *push buttons are operated
simultaneously in the operating mode i.e. when the
instrument is counting. See 5.24
7

4. INSTALLATION
5.1 Location
The BA564G Counter is housed in a robust IP66
glass reinforced polyester (GRP) enclosure
incorporating an armoured glass window and
stainless steel fittings making it suitable for exterior
mounting in most industrial on-shore and off-shore
installations. The Counter should be positioned
where the display is not in continuous direct sunlight.
Field wiring terminals are located on the rear of the
Counter assembly as shown in Fig 4.
To ensure electrical continuity between the two
conduit or cable entries, the enclosure back-box is
fitted with a bonding plate which includes an M4 earth
stud. This bonding plate may be mounted on the
inside or outside of the enclosure. If the carbon
loaded GRP enclosure is not bolted to an earthed
post or structure, this earth stud should be connected
to a local earth or the plant potential equalising
conductor.
An insulated M4 stud is provided in the bottom right
hand corner of the back-box for interconnecting cable
screens.
Alternatively the BA564G Counter may be pipe or
panel mounted using a BA393G pipe mounting kit or
a BA394 or BA395 panel mounting kit which are
available as accessories.
4.2 Installation Procedure
Fig 3 illustrates the instrument installation procedure.
A. Remove the Counter assembly by unscrewing
the four captive 'A' screws.
B. Mount the enclosure back-box on a flat surface
and secure with screws or bolts through the four
'B' holes. Alternatively use one of the pipe or
panel mounting kits which are available as
accessories.
C. Remove the temporary hole plug and install an
appropriate IP and temperature rated M20 x
1.5mm cable gland or conduit fitting. If two
entries are required, the supplied IP66 stopping
plug should be replaced with an appropriate IP
and temperature rated M20 x 1.5mm cable gland
or conduit fitting.
D. Feed the field wiring through the cable entry in
the back-box and connect the wires to the
terminals on the rear of the instrument assembly
as shown in Fig 4. Tighten cable glands to
ensure they are sealed and replace the
instrument assembly on the back-box. Finally
evenly tighten the four 'A' screws.

4.3 EMC
The BA564G 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 a common point.
4.4 Units of measurement and tag marking
on scale card.
The Counter's units of measurement and tag
information are shown on a scale card which slides
into the instrument.
New Counters are supplied with a printed scale card
showing the requested units of measurement and tag
information. If this information is not supplied when
the instrument is ordered, a blank scale card will be
fitted which can easily be marked on-site with a dry
transfer or a permanent marker. Custom printed
scale cards are available from BEKA associates as an
accessory.
To remove the scale card from a Counter carefully pull
the transparent tab at the rear of the instrument
assembly away from the assembly as shown in
Fig 5a.
Fig 5a Removing scale card
To replace the scale card carefully insert it into the
slot on the right hand side of the input terminals as
shown in Fig 5b. Force should be applied evenly to
both sides of the scale card to prevent it twisting.
The card should be inserted until about 2mm of the
transparent tab remains protruding.

5.0 CONFIGURATION & CALIBRATION
The BA564G 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.
The isolated pulse output, including configuration, is
described in section 6 of this manual. When factory
fitted optional alarms and the optional 4/20mA output
are included, additional functions appear in the
configuration menu which are described in section 9
of this manual.
All new BA564G Counters are supplied calibrated as
requested at the time of ordering. If calibration is not
requested, Counters will have factory default
configuration as shown in the following table, but can
easily be re-configured on-site.

Security code CodE 0000
Note: While the instrument is being configured
counting continues so that any input pulses occurring
during this time are recorded.
5.1 Calibration structure
Fig 6 shows the calibration structure of the BA564G
Counter. The two pulse inputs are processed by the
count function to produce a single output having the
selected arithmetic function, such as the sum of pulse
input A and pulse input b. This output is passed to
the 5cALE . R and 5CALE .T functions allowing the rate
and total displays to have different engineering units.
5CALE .tis a dividing factor that converts the output
from the Counter function into the required total
display in engineering units. e.g. if the output from
the Counter function is two pulses per pump stroke
and a total display of thousands of pump strokes is
required, 5CALE .tshould be set to 2000.
5CALE .ris a dividing factor that converts the output
from the Counter function into a rate display with
the required engineering units. e.g. if the output
from the Counter function is two pulses per pump
stroke and it is required to display the pump stroke
rate, 5CALE .rshould be set to 2.
The timebase t-bA5E is a multiplying factor that
determines if the instrument displays rate per
second, per minute or per hour.
The BA564G 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-A 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-A 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 BA564G 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 BA564G 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

dEbouncE is an adjustable sub-menu which
prevents the input miscounting when the input
pulse has noisy edges, such as those resulting
from a mechanical contact closing and bouncing.
The debounce function only applies to the input in
which the function is located.
Three levels of protection may be independently
selected for each input. The amount of debounce
applied depends upon the type of Counter input
that has been selected for the input in the
associated inP .tYPE function.
Select inPut-A 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 5.5.

The maximum counting frequency of the BA564G
depends upon the debounce level selected, the
shape of the input pulse and its amplitude. The
following table assumes a square wave input and
is included for guidance. The maximum counting
frequency will be lower if the input pulses have
sloping edges and the pulse amplitude only slightly
exceeds the input switching thresholds.

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

The counting edge function CntEdg-b is not
included in the configuration menu when the
BA564G Counter has a quadrature input A rEL b or
when input A is controlled by input b A Con b. In
quadrature mode the instrument will count up
when the rising edge of input-b leads the rising
edge of input-A.
See section 5.13.
5.12 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

Note:
1. For a quadrature input the two signals do not
require equal marks and spaces to achieve
reliable counting.
5.14 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
*button followed by the )button to enter the
selection and return to the configuration menu.

5.15 Lower display: di5P-2
This function turns the lower display on or off. When
turned off, the BA564G 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.
5.16 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 0 0 0.0.0.0.0.0 1 of 5 positions or absent
Rate 0.0.0.0.0 1 of 4 positions or absent
Lower display
Total 0.0.0.0.0.0 1 of 5 positions or absent
Rate 0.0.0.0.0 1 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 5.14) 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.
Note:
Adjustment of a decimal point position will
disable the following outputs which must be re-
enabled after the adjustment is complete:
Pulse output
Optional Alarm outputs
Optional 4/20mA output
5.17 Total scale factor: 5CALE .t
5CALE .tis a dividing factor adjustable between
0.0001 and 99999 that enables the total to be
displayed in engineering units. e.g. if one pulse
from the arithmetic count function represents 1
centimetre of dispensed cable and the total display
is required in metres, 5CALE .tshould be set to
100.0 which is the number of centimetres in a
metre. If just 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:
Pulse output
Optional Alarm outputs
Optional 4/20mA output
5.18 Rate scale factor: 5CALE .r
5CALE .ris a dividing factor adjustable between
0.0001 and 99999 that enables the rate display to
be shown in engineering units. e.g. if one pulse
from the arithmetic count function represents 2
pump strokes and the rate display is required in
pump strokes, 5CALE .rshould be set to 0.5. 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 5.19.
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 .rprompt in
the configuration menu.
Note:
Adjustment of 5cale .rwill disable the
following ouputs which must be re-enabled
after the adjustment is complete:
Pulse output
Optional Alarm outputs
Optional 4/20mA output
5.19 Timebase: t-bA5E
The timebase multiplies the rate display by 1, 60 or
3,600 depending upon whether the BA564G 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.
5.20 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
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.
