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.

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

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.

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.
