3. CERTIFICATION
The BA367NE has ATEX and IECEx Ex nA gas and
Ex tc dust certification. The main sections of this
instruction manual describes ATEX gas certification.
ATEX dust certification is described in Appendix 1, d
IECEx gas and dust certification in Appendix 2 and
ETL & cETL certification in Appendix 3.
3.1 ATEX Ex nA certification
Notified Body Intertek Testing and Certification Ltd
have issued the BA367NE with a Type Examination
Certificate number ITS16ATEX48409X. This has
been used to confirm compliance with the European
ATEX Directive for Group II, Category 3G
equipment. The instrument carries the Community
Mark and, subject to local codes of practice, may be
installed in any of the European Economic Area
(EEA) member countries and in the EEA EFTA
states, Iceland, Liechtenstein and Norway. ATEX
certificates are also acceptable in Switzerland and
Turkey. The European Commission's Blue Guide
lists the member states, overseas countries and
territories that have adopted harmonisation
legislation.
This section of the instruction manual describes
ATEX installations in explosive gas atmospheres
conforming with EN 60079-14 Electrical installations
design, selection and erection. When designing
systems for installation outside the UK the local
Code of Practice should be consulted.
3.2 Zones, gas groups and T rating
The Counter has been certified as Group II Category
3G Ex ic nA IIC T5 Gc apparatus. This is non-
sparking apparatus complying with EN 60079-15
Equipment protection by type of protection 'n' that
minimises the risk of arcs or sparks capable of
creating an ignition hazard occurring during
conditions of normal operation.
The Counter's front panel push button contacts are
non incendive and have been certified intrinsically
safe Ex ic without an external Zener barrier or
galvanic isolator, as shown on the Type Examination
Certificate. This allows the Counter to be adjusted
and configured live when installed in a Ex n panel
enclosure located in Zone 2.
When connected to a suitable system and correctly
mounted in a panel enclosure complying with the
requirements for Type of protection 'n', the panel
enclosure containing the BA367NE Counter may be
installed in:
Zone 2 explosive gas air mixture not
likely to occur, and if it does
will only exist for a short time.
Be used with gases in groups:
Group A propane
Group B ethylene
Group C hydrogen
In gases that may safely be used with equipment
having a temperature classification of:
T1 450oC
T2 300oC
T3 200oC
T4 135oC
T5 100oC
At ambient temperatures between -40 and +60oC.
This allows use with all commonly used industrial
gases except carbon disulphide CS2.
3.3 Special conditions for safe use
Special conditions for safe use are specified by the
Ex nA certificate indicated by the certificate number's
'X' suffix. These state that the BA367NE Counter
should be:
a. Mounted such that the instrument terminals
are protected by at least an IP54 enclosure
certified to IEC 60079-0 or IEC 60079-15 as
appropriate.
b. Be supplied from limited energy circuits with
output parameters in normal operation equal
to, or less than the instruments input
parameters.
These special conditions for safe use can be
satisfied by mounting the BA367NE in an Ex n, Ex e
or Ex p panel enclosure. For ATEX Category 3
installations in Zone 2, self or third party certified
Ex n, Ex e or Ex p panel enclosures may be used.
Additional requirement apply for non-metallic panel
enclosures.
3.4 Power supply
The input safety parameters for the power supply
terminals 1 and 2 are:
Ui = 30dc
Ii = 100mA
This allows the BA367NE to be powered from any dc
supply which in normal operation has an output
voltage of less than 30V. See section 4.1 for power
supply recommendations.
3.5 Pulse input
The BA367NE Counter has a single pair of pulse
input terminals 5 and 6 that may be configured for
use with different types of sensor.
For sensors that require energising to determine
their state, such as switch contacts or a 2-wire
proximity detector, an external link between
terminals 3 & 4 of the BA367NE connects an internal
7V, 6mA supply to the input terminals. Energising is
6

not required when the Counter input is connected to
a voltage pulse source.
Fitting an external link between terminals 3 & 4
changes the Counter's pulse input safety parameters
in normal operation as shown below. This table also
shows the types of sensor requiring energising (link
fitting).
Safety parameters
Input Output
Type of input Link 3 & 4 Ui Uo Io
Switch contact Yes 15V 10.5V 9.2mA
Proximity detector Yes 15V 10.5V 9.2mA
Open collector Yes 15V 10.5V 9.2mA
Magnetic pick-off No 30V 1.1V 0.5mA
Voltage input (low) No 30V 1.1V 0.5mA
Voltage input (high) No 30V 1.1V 0.5mA
3.6 Remote reset terminals
The BA367NE total display my be reset to zero by
connecting the external reset terminals RS1 and
RS2 together for more than one second. The two
reset terminals have the following safety parameters
in normal operation:
Ui = 30V
Uo = 3.8V
Io = 1mA
3.7 Certification label information
The Counter certification information label is fitted in
a recess on the top outer surface of the enclosure. It
shows the ATEX and IECEx certification information
plus BEKA associates name, location, year of
manufacture and the instrument serial number.

4. SYSTEM DESIGN FOR HAZARDOUS AREAS
When correctly installed in Zone 2 the BA367NE
Counter may be connected to almost any apparatus
in the safe area and to Ex n, Ex e, Ex p and Ex d
protected apparatus located in Zone 2. Because
the BA367NE is not certified intrinsically safe it
should not be connected to an intrinsically safe
system.
BEKA Application Guide AG310, Guide for
Installation of [extra low voltage d.c.] Ex nA
instrumentation, which can be downloaded from
www.beka.co.uk, contains explanations and
recommendations for the installation of Ex nA
equipment.
In addition to being able to be connected to other
equipment in the safe area and in Zone 2, the
BA367NE may also be connected to suitably
protected and certified equipment located in Zone 1.
This is illustrated in Fig 5 and explained in
Application Guide AG310.
There are four design requirements:
1. The BA367NE must be installed in a panel
enclosure complying with the requirements for
Ex n protection as shown in section 5 of this
manual.
2. The BA367NE should be powered from a
circuit that has output safety parameters in
normal operation equal to, or less than, the
input safety parameters for terminals 1 and
2 specified by the BA337NG ATEX Type
Examination Certificate.
3. Hazardous area apparatus to which the
BA367NE is connected should be protected
by a technique suitable for the Zone in
which the equipment is located such as Ex n
or Ex e if located in Zone 2. Equipment
protected by intrinsic safety should not be
connected to a BA367NE.
4. Wiring should comply with Clause 9 of
EN 60079-14.
When designing a system it is important to
remember that terminals 2, 6 and RS2 are
interconnected within the BA367NE. See Fig 1.
7

4.1 Power supply
The BA367NE Counter requires a minimum of 10V
between terminal 1 & 2 and consumes:
10mA without optional backlight
plus 6mA when terminals 3 & 4 are linked
A 24V dc regulated supply with a current limit
located in a safe area is suitable. The power supply
should meet the requirements for personnel safety
so that ‘live maintenance’ can safely be performed.
The implicit requirement for galvanic isolation from
the mains supply ensures that the possible
difficulties from circulating earth currents caused by
mains faults is minimised. In European terms if the
power supply is CE marked it is almost certainly
acceptable.
To comply with the requirements of EN 60079:14
Electrical installations design, selection and erection,
each of the wires entering the hazardous area
should be individually fused and contain a means of
isolation. These two requirements may be satisfied
by using DIN rail mounted terminals incorporating an
easily removable fuse which can be extracted to
achieve isolation as shown in Fig 2. Clear
identification of, and easy access to the means of
isolation is essential for their effective use. It is also
necessary to ensure that the maintenance procedure
makes sure that unauthorised re-closure of the
switches does not occur. It is not considered
necessary to have a means of isolation or electrical
protection for the screen.
Fig 2 DIN rail mounting terminals incorporating a
fuse
For some applications Ex nA instrumentation
energised by a current limited power supply or
instrument that can be switched off, is considered
adequate and to comply with the requirements of the
standard.
4.2 Pulse input
The BA367NE can count and display the total
number of input pulses received from a wide variety
of sensors located in a Zone 2 hazardous area or in
a safe area. Fig 3 shows the connections when the
sensor is located in Zone 2 and Fig 4 the
connections required when the sensor is in a safe
area.
Fig 3 Connections for sensor in Zone 2
Fig 4 Connections for sensor in safe area
8

Providing the BA367NE Counter is correctly installed
in an Ex n panel enclosure located in Zone 2, the
input terminals may be connected to a certified
sensor located in Zone 1 as shown in Fig 5. The
sensor should have Ex e or Ex d certification
permitting installation in Zone 1. Intrinsically safe
Ex i certified sensors should not be used.
Fig 5 Connection to an Ex d or Ex e sensor in Zone 1
4.2.1 Input switching thresholds
For reliable operation the Counter pulse input 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
Sensors with a switch contact, proximity detector or
an open collector output require energising which is
achieved by linking Counter terminals 3 and 4.
4.2.2 Switch contact input
Any mechanically or magnetically activated switch
contact speed sensor located in Zone 2 or in the
safe area may be directly connected to the pulse
input terminals 5 and 6 which are non incendive,
providing the sensor and associated wiring can
withstand a 500V rms insulation test to earth. Most
magnetically activated reed relays comply with these
requirements. The BA367NE contains a
configurable debounce circuit to prevent contact
bounce being counted. See section 6.6.
4.2.3 Open collector input
Open collector sensors located in Zone 2 or in the
safe area may be directly connected to input
terminals 5 & 6 providing the sensor and associated
wiring can withstand a 500V rms insulation test to
earth.
The BA367NE contain a configurable debounce
circuit to prevent false triggering. See section 6.6.
4.2.4 2-wire proximity detector input
Most Zone 2 certified NAMUR 2-wire proximity
detectors may be directly connected to a BA367NE
input terminals 5 & 6, providing the minimum
operating voltage of the proximity detector is greater
than 7.5V. The sensor and the associated wiring
should be able to withstand a 500V rms insulation
test to earth.
The BA367NE contain a configurable debounce
circuit to prevent false triggering. See section 6.6.
4.2.5 Magnetic pick-off input
Magnetic pick-off sensors usually have a low level
ac voltage output which a BA367NE Counter can
sense when configured for a CoiL input. The
Counter input terminals 5 and 6 may be connected
to any Zone 2 certified magnetic pick-off output
sensor, providing the output in normal operation is
equal to or less than 30V the Counter's Ui. The
sensor and associated wiring should be able to
withstand a 500V rms insulation test to earth.
The BA367NE contain a configurable debounce
circuit to prevent false triggering. See section 6.6.
4.2.6 Voltage pulse input
Two voltage pulse input ranges are selectable in the
BA367NE Counter configuration menu, VoLt5 L and
VoLt5 H. The Counter input terminals 5 and 6 may
be connected to any Zone 2 voltage pulse output
sensor, providing the output in normal operation is
equal to or less than 30V the Counter's Ui. The
sensor and associated wiring should be able to
withstand a 500V rms insulation test to earth.
The BA367NE contain a configurable debounce
circuit to prevent false triggering. See section 6.6.
4.3 Remote reset
The BA367NE Counter's total display may be
remotely reset to zero by connecting terminals RS1
and RS2 together. Permanent interconnection
inhibits the Counter. Remote resetting may be
accomplished by any mechanically operated switch
located in Zone 2 as the Counter's reset circuit is
non incendive. The reset switch and the associated
wiring should be able to withstand a 500V rms
insulation test to earth.
A BA367NE may also be remotely reset from the
safe area. Any switch may be used. Fig 4 illustrates
how a BA367NE may be reset from both the safe
and the hazardous area.
The BA367NE 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 6.19

5. INSTALLATION
5.1 Location
When installed in a panel enclosure complying with
the requirements for Ex n protection the BA367NE
may be located in a Zone 2 hazardous area
providing that the operating temperature is between
–40°C and +60°C and the installation complies with
the Counters certification requirements. Certified
Ex e panel enclosures are frequently used as Ex n
panel enclosures.
The BA367NE Counter has a stainless steel
housings with a 7J front of panel impact resistance
incorporating a 10mm thick toughened glass window
which can withstand a 4J impact. This, together
with a captive silicone gasket which seals the joint
between the instrument and the panel, enclosure
provides IP66 ingress protection. The BA367NE has
IP20 rear protection.
Although the front of the BA367NE Counter has IP66
protection, it should be shielded from continuous
direct sunlight and severe weather conditions.
Fig 6 shows the overall dimensions of the BA367NE
together with the recommended panel enclosure cut-
out dimensions.
5.2 Installation Procedure
a. Cut the aperture specified in Fig 6 into the panel
enclosure. Ensure that the edges of aperture are
de-burred.
b. Inspect the Counter's captive gasket and ensure
that it is not damaged before inserting it into the
panel enclosure aperture.
c. If the enclosure panel is less than 1.0mm thick, or
is non-metallic, an optional BEKA stainless steel
support plate should be slid over the rear of the
indicator before the panel clamps are fitted to
evenly distribute the clamping force and prevent
the enclosure panel being distorted or creeping.
d. Slide a panel clamp into the two grooves at each
corner of the indicator housing with the M3 stud
protruding through the hole at the rear of the
clamp. Fit the stainless steel spring washer over
the stud and secure with the stainless steel wing
nut.
e. Evenly tighten the four clamps to secure the
instrument. The recommended minimum
tightening torque for each wing nut is 22cNm
(1.95 lbf in).
f. Connect the panel enclosure wiring to the rear
terminal blocks. To simplify installation, the
terminals are removable so that wiring can be
completed before the instrument is installed.
Wiring should be supported to prevent damage
resulting from vibration.
g. Finally, fit a silicone rubber push-on cap to the
end of each M3 threaded rod.

Fig 7 Installation procedure
5.3 Counter earthing
The BA367NE has an M4 earth stud on the rear
panel which should be electrically connected to the
panel enclosure in which the Counter is mounted, or
to the plant equipotential conductor.
5.4 EMC
The BA367NE 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 in the
safe area.
Fig 8 Terminals for field wiring
5.5 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 9. Thus the scale
card can easily be changed without dismantling the
Counter or removing it from the Ex n enclosure in
which it is mounted.
New 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 of measurement is available as an
accessory from BEKA associates. Custom printed
scale cards can also be supplied.
To change a scale card, unclip the protruding end of
the flexible strip 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 Counter rear
panel.
Align the self-adhesive printed
scale card onto the flexible strip
and insert the strip into the
indicator as shown below.

6.0 CONFIGURATION & CALIBRATION
The BA367NE 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 11.
Each menu function is summarised in section 6.3 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 9.
All new BA367NE 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.

occurring during this time are recorded.
6.1 Configuration structure
Fig 10 shows the calibration structure of the
BA367NE 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 BA367NE uses ‘real’ decimal points. Moving the
position of a decimal point in a scale factor will affect
the instrument calibration.

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 11.
When returning to the display mode following
reconfiguration, the BA367NE 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 BA367NE 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.
6.3 Summary of configuration functions
This section summarises all the configuration
functions. When read in conjunction with Fig 11 it

5CALE .tTotal Scale Factor
5CALE .T is a dividing factor that
converts the number of input pulses
into the required total display in
engineering units. 5CALE .tmay be
adjusted between 0.0001 & 99999.
e.g. if one input pulse 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.
The total display is independent of
the rate display.
See section 6.12
5CALE .rRate scale factor
5CALE .ris a dividing factor that
converts the input pulse rate into the
required rate display in engineering
units. 5CALE .rmay be adjusted
between 0.0001 and 99999. e.g. if
one pulse represents 2 pump
strokes and the rate display is
required in pump strokes, 5CALE .r
should be set to 2.0.
The rate display is independent of
the total display.

6.4 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.
6.5 Input type: inP.tYPE
inP .tYPE is a sub-menu in the inPut function which
defines the type of input transducer 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.
One of following six types of input may be selected:
Switching
thresholds
Low High
oP .CoL Open collector 22 10k
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 +28V.
2. For transducers connected to the input that
require energising i.e. proximity detectors,
switch contacts or open collector transducers,
terminals 3 & 4 of the BA367NE 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 6.6 for maximum counting
frequency.
6.6 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 6.5.

The maximum counting frequency of the BA367NE
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.

EdGE 2
Type of input Counting edge
Voltage High to low
Switch contact Open to closed
Open collector Open to closed
Proximity detector Low to high current
6.8 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.
6.9 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 *
button followed by the )button to enter the
selection and return to the configuration menu.
6.10 Lower display: di5P-2
This function turns the lower display on or off.
When turned off, the BA367NE 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.
6.11 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 000.0.0.0.0.0 1 of 5 positions or absent
Rate 00.0.0.0.01 of 4 positions or absent
Lower display
Total 0.0.0.0.0.0 1 of 5 positions or absent
Rate 0 0.0.0.0.01 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 6.9) 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.
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.

6.12 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.
6.13 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 6.14.
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.
6.14 Timebase: t-bA5E
The timebase multiplies the rate display by 1, 60 or
3,600 depending upon whether the BA367NE
Counter is required to display rate per second, per
minute or per hour. See Fig 10.
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.
6.15 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.
