1. DESCRIPTION
The BA488CF-P PROFIBUS Display is an
intrinsically safe instrument that can display up to
eight fieldbus process variables, together with their
units of measurement and tag information. The
instrument is bus powered so no additional power
supply is required.
Order Communication Function
Code Protocol Blocks
BA488CF-P PROFIBUS PA Eight Analogue
outputs (8 x AO)
Six Digital inputs
(6 x DI)
The instrument’s communications protocol is
shown on the rear panel. The ‘-P’ order code
suffix also indicates the protocol but is not shown
on the instrument certification label. There is an
alternative version of the fieldbus display, order
code BA488CF-F for use on FOUNDATION™
fieldbus systems.
Configuration may be performed by either a DPV 0
user PRM data download, or by a DPV 1
configurator and if required the instrument address
may be entered via the instrument’s front panel
push buttons. The required GSD files are available
for downloading from both the PROFIBUS and
BEKA websites.
Eleven selectable standard display formats enable
one, two, three, four or eight process variables,
some with bargraphs to be displayed
simultaneously on one screen.
The six front panel push buttons that control the
instrument display may also be used for returning
operator acknowledgements, thus enabling the
BA488CF-P PROFIBUS display to function as a
simple operator interface. If larger industrial push
buttons are required for entering these
acknowledgements, up to six external switches
may be connected to the BA488CF-P. These
switch inputs may also be used for returning the
status of plant contacts to the host using the DI
function blocks.
The BA488CF-P PROFIBUS Display can be
supplied with six optional alarm outputs that may
be linked to any of the displayed fieldbus variables.
These alarm outputs are locally activated from the
fieldbus variable and are configured via the
instrument menus and push buttons. They can not
be controlled via the fieldbus.
The instrument has been certified intrinsically safe
by European Notified Body Intertek Testing
Services (ITS) to the ATEX Directive 94/9/EC for
use in explosive gas atmospheres.
For use in the USA the instrument has intrinsic
safety and nonincendive FM Approval – see
Appendix 2, plus IECEx intrinsic safety approval
for international applications – see Appendix 3.
Housed in a robust 72 x 144 panel mounting DIN
enclosure, the BA488CF-P PROFIBUS display has
an IP66 front panel and is supplied with a gasket to
seal the joint between the instrument and the
panel.
1.1 Documentation
This instruction manual describes system design,
conditioning and installation of the BA488CF-P
PROFIBUS display. For detailed commissioning
information please refer to the PROFIBUS
Interface Guide that can be downloaded from the
BEKA website www.beka.co.uk
1.2 Version 3.0 firmware
This manual describes BA488CF-P PROFIBUS
displays employing version 3.0 firmware that was
released in July 2010 and is not backwards
compatible with earlier versions.
Version 3.0 firmware provides
Addition of (6 x DI) function blocks to return
switch status to host.
Fieldbus address entry via instrument push
buttons.
Addition of DPV 0 configuration
Addition of two standard screens allowing
eight fieldbus variables to be simultaneously
displayed.
Removal of text display facilities
When using the ▼or ▲button to select
input, or groups of inputs to be displayed,
unused inputs can now be skipped.
The instrument’s firmware version can be
established using the ‘Unit Info’ function in the
main configuration menu – see section 6.3.9 of this
manual. Version 3.0 firmware is shown as
SW480F-02-300.
For BA488CF-P PROFIBUS displays employing
version 2.0 firmware, please refer to the BA488CF
Intrinsically safe field mounting fieldbus display
Issue 10 manual dated 3rd November 2009 which
may be downloaded from the obsolete products
section of the BEKA website.

2. OPERATION
Fig 1 shows a simplified block diagram of the
BA488CF-P PROFIBUS display. When the
optional alarms and external switches are not
used, the instrument only requires a two-wire
connection to the fieldbus.
How much of the BA488CF-P PROFIBUS display
configuration can be performed via the fieldbus
depends upon the system host. Parameters that
can not be configured via the fieldbus can be set
using the configuration menu shown in Fig 7 and
the four front panel push buttons.
Fig 1 Simplified block diagram of BA488CF-P
2.1 Controls
The user can scroll through the display screens by
operating the ▼or ▲push buttons. The number
of screens available depends upon how the
BA488CF-P PROFIBUS display has been
configured and the number of process variables
that are to be displayed. If one fieldbus variable
per screen has been configured and eight
variables are to be displayed, eight screens will be
present; if two fieldbus variables per screen have
been configured and six variables are to be
displayed, three screens will be available.
If enabled, operating the Pand ▲push-buttons
simultaneously activates the Quick Access Menu,
allowing the user to adjust the display contrast
without providing access to any of the other
configuration parameters. Additional security may
be provided by an optional access code.

3. INTRINSIC SAFETY CERTIFICATION
3.1 ATEX certificate
The BA488CF-P has been issued with EC-Type
Examination Certificate by Notified Body Intertek
Testing Services (ITS) confirming compliance with
the European ATEX Directive 94/9/EC for Group II,
Category 1, gas atmospheres, EEx ia IIC T4. The
instrument bears the Community Mark and, subject
to local codes of practice, may be installed in any
of the European Economic Area (EEA) member
countries. ATEX certificates are also acceptable
for installations in Switzerland. This manual
describes installations which conform with
EN 60079: Part 14 Electrical Installation in
Hazardous Areas. When designing systems for
installation outside the UK, the local Code of
Practice should be consulted. Some of the
standards specified may have subsequently been
deharmonised, please see BEKA Declaration of
Conformity for current conformity.
3.2 Zones, gas groups and T rating
The BA488CF-P has been issued with EC Type
Examination certificate ITS04ATEX22779
confirming that it complies with the requirements
for Group II Category 1 G Ex ia IIC T4 (Tamb –40
to 60°C) specified in the ATEX Directive. When
connected to a suitable system the BA488CF-P
may be installed in:
Zone 0 explosive gas air mixture
continuously present.
Zone 1 explosive gas air mixture
likely to occur in normal
operation.
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
Having a temperature classification of:
T1 450°C
T2 300°C
T3 200°C
T4 135°C
At an ambient temperature between –40 and
+60°C.
Note: the guaranteed operating temperature range
of the Fieldbus Display is –20 to +60°C
This allows the BA488CF-P to be installed in all
Zones and to be used with most common industrial
gases.
WARNING installation in Zone 0
When installed in a Zone 0 potentially
explosive atmosphere requiring apparatus
of Category 1G, the fieldbus display shall be
installed such that even in the event of rare
incidents, an ignition source due to impact
or friction between the aluminium enclosure
at the rear of the instrument mounting panel
and iron/steel is excluded.
3.3 Fieldbus connection
The BA488CF-P PROFIBUS display is powered
and communicates via the fieldbus, which is
connected to terminals 1 and 2. These terminals
comply with the Fieldbus Intrinsically Safe Concept
(FISCO) defined in EN 60079 Part 27, which
simplifies intrinsic safety system design.
The BA488CF-P may also be connected to non
FISCO compliant fieldbus segments by using the
entity concept to assess safety.
Terminals 1 and 2 of the BA488CF-P Fieldbus
Display are not polarised and have the following
safety parameters:
Ui = 17.5V dc
Ii = 380mA dc
Pi = 5.32W
For non FISCO compliant segments, the safety
parameters of the power supply or isolator
powering the fieldbus segment must be equal to or
less than these figures.
The maximum equivalent capacitance and
inductance at terminals 1 & 2 of the BA488CF-P
Fieldbus Display are:
Ci = 1nF
Li = 8µH
To determine cable parameters for non FISCO
compliant segments, the sum of Ci and Li of all the
field devices should be subtracted from the
maximum cable parameters permitted by the
device powering the fieldbus segment.
3.4 External switches
For applications requiring operator inputs to be
made by large industrial push buttons, terminals
S1 to S7 facilitate external switches to be
connected to the Fieldbus Display. When external
switches are connected, the BA488CF-P may be
configured so that the front panel push buttons
continue to function or are disabled.
Terminals S1 to S7 have the following combined
output safety parameters:

6
Uo = 14.7V dc
Io = 146.7mA dc
Po = 0.58W
The switches and associated wiring connected to
the terminals must comply with the requirements
for simple apparatus. i.e. the switch must be
mechanically activated and have IP20 protection,
and both the switch and the wiring must be
capable of withstanding a 500V rms insulation test
to earth for one minute. Most industrial push
buttons and wiring satisfy these requirements.
The input safety parameters of terminals S1 to S7
are zero, therefore only switches or intrinsically
safe relays may be connected.
The total maximum permitted cable parameters for
all the cables connected to terminals S1 to S7 in a
IIC hydrogen gas must be less than:
Co = 0.22µF
Lo = 0.26mH
Although these parameters are not restrictive, for
reliable operation it is recommended that the
cables between the fieldbus display and the
external push buttons are less than 5m long.
3.5 Alarm outputs
Each of the six alarm outputs is a separate
galvanically isolated solid state switch. The EC-
Type Examination Certificate specifies that under
fault conditions the voltage, current and power at
each switch output will not exceed those specified
for simple apparatus in section 5.7 of EN 60079-
11. This allows each of the BA488CF-P alarm
outputs to be connected to any intrinsically safe
circuit protected by a certified Zener barrier or
galvanic isolator providing that the output
parameters of each circuit are less than:
Uo = 28V dc
Io = 200mA
Po = 0.84W
The maximum equivalent capacitance and
inductance of each BA488CF-P alarm output is:
Ci = 40nF
Li = 20µH
To determine the maximum permissible cable
parameters, Ci and Li must be subtracted from the
maximum cable capacitance and inductance
specified by the system certificate of the circuit
connected to the switch.
3.6 Certification Label Information
The certification label is fitted in a recess on the
top outer surface of the enclosure. It shows the
ATEX certification information, a statement that the
instrument is a FISCO Field Device, plus BEKA
associates name and location. Non European
certification information may also be included.
4. SYSTEM DESIGN FOR HAZARDOUS
AREAS
4.1 FISCO Systems
The BA488CF-P may be connected to any FISCO
compliant fieldbus segment providing that the
power supply or isolator powering the segment can
provide 25mA required by the BA488CF-P
PROFIBUS display.
Fig 2 shows a typical fieldbus segment. To comply
with FISCO requirements, the power supply,
terminators, field devices and the interconnecting
cables must conform with EN 60079 part 27.
Fig 2 FISCO fieldbus system

7
4.2 Non FISCO Systems
If the BA488CF-P PROFIBUS display is to be
connected to a fieldbus segment that does not
comply with FISCO requirements, the safety
parameters of the power supply and the
PROFIBUS Display must be compared using the
entity concept.
The maximum output safety parameters of the
device powering the fieldbus segment must be
equal to, or less than, the input safety parameters
of terminals 1 & 2 of the BA488CF-P PROFIBUS
display, namely:
Ui = 17.5V dc
Ii = 380mA dc
Pi = 5.32W
The maximum permitted cable parameters for the
fieldbus segment must be reduced by the
equivalent internal capacitance Ci and inductance
Li of the BA488CF-P. The BA488CF-P equivalent
capacitance and inductance are very small and
make little practical difference.
Ci = 1nF
Li = 8µH
4.3 External switches
For applications requiring operator inputs to be
made by large industrial push buttons, terminals
S1 to S7 allow up to six external switches to be
connected to the BA488CF-P PROFIBUS Display.
When external switches are connected the front
panel push buttons may be operated in parallel or
disabled – see section 6.3.7
For installation in a hazardous area the switches
and associated wiring must comply with the
requirements for simple apparatus. i.e. the switch
must be mechanically activated and have IP20
protection, and both the switch and the wiring must
be capable of withstanding a 500V rms insulation
test to earth for one minute. Most industrial push
buttons and wiring satisfy these requirements.
Although the allowable cable parameters are large,
it is recommended that the cables are less than 5m
long.
If a safe area switch is to be connected to a
Fieldbus Display located in a hazardous area, the
switch contact must be transferred via a certified
intrinsically safe relay or a galvanic isolator having
zero output safety parameters as shown in Fig 3.
Fig 3 External push button switch in safe area
4.4 Alarm outputs
Each alarm output is a galvanically isolated single
pole solid state switch output as shown in Fig 4.
Fig 4 Equivalent circuit of each switch output
The outputs are polarised and current will only flow
in one direction. Odd numbered terminals should
be connected to the positive side of the supply.
Ron = 5+ 0.7V
Roff = greater than 1M
Note: Because of the series protection diode,
some test meters may not detect a closed alarm
output
WARNING
These Alarm Outputs should not be used
for critical safety applications such as an
emergency shut down system.
When the BA488CF-P PROFIBUS display is
disconnected from the fieldbus, or the fieldbus is
de-energised all the alarm outputs will open
irrespective of how they have been configured.

5. INSTALLATION
5.1 Location
The BA488CF-P PROFIBUS display is housed in a
robust aluminium enclosure with a toughened
glass window mounted in a Noryl bezel. The front
of the instrument provides IP66 protection and a
gasket seals the joint between the instrument
enclosure and the panel. The instrument may be
installed in any panel providing the environmental
limits shown in the specification are not exceeded.
Fig 5 shows the overall dimensions of the
BA488CF-P and the panel cut-out. To achieve an
IP66 seal between the instrument enclosure and
the panel, the smaller cut-out must be used and
the instrument secured with four panel mounting
clips.
The BA488CF-P liquid crystal display has
maximum contrast when viewed from directly
ahead and slightly below the centre line of the
instrument.
Fig 5 BA488CF-P dimensions
5.2 Installation Procedure
a. Insert the BA488CF-P into the instrument
panel cut-out from the front of the panel.
b. Fix panel mounting clips to opposite sides of
the instrument and tighten until the
instrument is secure. Four clips are required
to achieve an IP66 seal between the
instrument enclosure and the panel.
c. Connect the panel wiring to the rear terminal
block(s) as shown in Fig 6. To simplify
installation, the terminals are removable so
that panel wiring can be completed before
the instrument is installed.
Fig 6 Installation and terminal connections

5.3 EMC
The BA488CF-P complies with the requirements of
the European EMC Directive 2004/108/EC. For
specified immunity all wiring should be in screened
twisted pairs with the screens connected to the
potential equalising network as recommended in
EN 60079-14.

6. DISPLAY & ALARM CONFIGURATION
In addition to loading the BA488CF-P PROFIBUS
display GSD files onto the system host and
defining up to eight fieldbus variables that are to be
displayed, the instrument address, display and
alarms, if fitted, have to be configured. How
much of this configuration can be performed via
the fieldbus depends upon the system host.
Parameters that can not be configured via the
fieldbus, may be set via the four front panel push
buttons.
All the display and alarm configuration functions
are contained in an easy to use menu that is
shown in Fig 7. Where necessary the sub-menus
contain on-screen prompts to guide the user
through each adjustment.
When navigating through the configuration menu,
the push-button(s) should be held until the required
screen is displayed.
6.1 Default configuration
Unless otherwise requested at the time of ordering,
BA488CF-P PROFIBUS displays will be supplied
configured as follows:

6.2 Accessing the display configuration
menus
Throughout this manual the four BA488CF-P push
buttons used for configuration are identified P E ▼
▲, and legends displayed by the instrument are
shown within inverted commas e.g. 'Enter Access
Code'.
Operating the Pand Epush buttons
simultaneously accesses the display configuration
menu. If the BA488CF-P is not protected by an
access code the main menu will be displayed. If
an access code other than the default code 0000
has already been entered, the BA488CF-P will
request that the access code be entered.
Using the ▼or ▲button adjust the first digit of the
code which will be flashing. Pressing Pwill
transfer control to the next digit, which should be
adjusted in the same way. When all four digits
have been set, pressing the Ebutton will enter the
access code. If the code is correct the main
menu will be displayed, if the code is incorrect
‘Invalid Code’ will be displayed.
When entering an access code, timeout will occur
and the instrument will automatically return to the
operating mode ten seconds after a push button
was last operated. In all other menus, timeout
occurs after sixty seconds.
The structure of the display configuration menu is
shown in Fig 7. Navigation is achieved by
highlighting the required function using the ▼and
▲buttons and then operating the Pbutton to
display the selected function sub-menu, from
which a further selection or adjustment may be
made. Operating the Ebutton moves the display
back up one level.
A flashing highlight indicates that an option or
alphanumeric character may be selected using the
▼and ▲buttons and entered using the Ebutton.
If only one entry or adjustment can be made in a
sub-menu, the display will automatically move up
one menu level when the adjustment is entered. If
more than one adjustment can be made in a sub-
menu, the highlight may be moved to the second
variable using the ▼or ▲button after the first
setting has been entered. Operating the Pbutton
allows the second variable to be adjusted.
When multiple numeric or alpha characters are
adjusted e.g. an alarm setpoint or a tag legend, the
adjustment is made one digit at a time using the ▼
and ▲buttons. After the first flashing digit has
been set as required, the flashing highlight can be
moved to the next digit by operating the Pbutton.
When all digits have been set, operating the E
button will enter the setting.
Following completion of the instrument
configuration, the Ebutton should be operated to
step the display back to the main menu. One more
operation of the Ebutton will then return the
BA488CF-P to the operating mode.

6.3 Configurable functions
This section provides an explanation of each
configurable function and should be read in
conjunction with Fig 7. See section 6.3.11 for
entering the instruments PROFIBUS PA address.
6.3.1 Screens (Display format)
The BA488CF-P can display up to eight fieldbus
variables that are identified as IN_1 to IN_8. The
fieldbus variable that each one represents is
determined by the BA488CF-P configuration at the
fieldbus system host - see the PROFIBUS
Fieldbus Interface Guide which may be
downloaded from the BEKA website.
This sub-menu allows one of eleven standard
display formats to be selected. The standard
formats contain one, two, three, four or eight
fieldbus variables some with bargraphs as shown
below.

Four variables + vertical bargraphs
Eight variables + horizontal bargraphs

12
6.3.2 Input Settings
Each of the eight fieldbus variable inputs may be
scaled before being displayed as shown below.
Display = (Gain x Fieldbus variable) + Offset
The sub-functions for each of the eight inputs are:
‘Offset’ Adds a positive or negative offset to
the fieldbus variable before it is
displayed.
‘Gain’ Multiplies the fieldbus variable by a
factor before it is displayed.
‘Bar Lo’ Defines the bargraph lower limit
‘Bar Hi’ Defines the bargraph higher limit
‘Format’ Defines the position of the displayed
decimal point.
Six options are available:

If a negative number is likely to be displayed, a
digit must be allocated for the negative sign. If the
display overanges all the digits will display ‘?’.
For all options leading zeros, apart from the zero in
front of a decimal point, are automatically
suppressed.
6.3.3 Tags
Each of the eight fieldbus variables may be
displayed with an individual tag that can contain up
to sixteen alphanumeric characters. This menu
allows these tags to be entered. After selecting
the required variable, the tag legend is entered
character by character using the ▼and ▲push
buttons. Numbers, upper & lower case letters and
symbols are available.
6.3.4 Units
Each of the eight fieldbus variables may be
displayed with units of measurement that can
contain up to eight alphanumeric characters. This
menu allows these units of measurement to be
entered. After selecting the required variable, the
unit of measurement is entered character by
character using the ▼and ▲push buttons.
Numbers, upper & lower case letters and symbols
are available.
6.3.5 Alarms
Alarm menus are only included when the
BA488CF-P is fitted with optional alarm
outputs. Outputs are locally activated from the
fieldbus variables and are configured via the
instrument menus and push buttons. They
can not be controlled via the fieldbus.
Each of the six alarms may be linked to any one of
the eight fieldbus variables displayed by the
BA488CF-P. Each alarm output can be
conditioned to function as a high or a low alarm, or
as a combined high and low alarm. The output
can be conditioned as normally open ‘N/O’ or
normally closed ‘N/C’ in the non-alarm condition.
Irrespective of settings all alarm outputs will be
open when the instrument is not powered from the
fieldbus.
When an alarm is activated, the associated
fieldbus variable display flashes, i.e. alternates
between dark figures on a light background and
light figures on a dark background.
There are eight alarm-conditioning sub-menus.
6.3.5.1 Alarm Summary
Shows to which PROFIBUS variable each alarm is
linked and how each alarm has been conditioned.
i.e. high, low, or combined high & low alarm with
normally open or closed output. No adjustments
can be made via this sub-menu.

13
6.3.5.2 Alarm Activation
PROFIBUS variables that have not been validated
are displayed with dark characters on a light
background, and some screen formats also
contain a status indication. This sub-menu allows
the alarm outputs to be conditioned so that they
only operate with validated PROFIBUS data, or to
operate irrespective of data validity.
6.3.5.3 Alarm Output
There is a separate sub-menu for each of the six
alarm outputs; these link the alarm to one of the
displayed PROFIBUS variables and define the
alarm function and the setpoints.
To link the alarm to a displayed variable, position
the highlight over the ‘IN_n’ field, press Pand
using the ▼or ▲button select the required input
source. Enter the selection by pressing the E
button.
Each alarm output can be N/O or N/C in the non-
alarm condition. To change the setting, position the
highlight over the ‘N/O or N/C’ field, press Pand
use the ▼or ▲button to toggle the setting. Enter
the selection by pressing the Ebutton.
Each alarm output has three functions that can be
independently enabled to condition the output as a
low or high alarm, or as a combined low and high
alarm, either with or without hysteresis.
The required functions can be individually enabled
by positioning the highlight over the Enb/Dis
(Enabled/Disabled) column, pressing Pand
toggling the function to the required state, then
entering the selection by pressing the Ebutton.
Alarm setpoints are entered digit by digit. Place the
highlight over the setpoint to be adjusted and press
P; the flashing digit to be adjusted may then be
selected by again pressing P. When all the digits
have been adjusted, operating the Ebutton enters
the value and moves the menu up one level.
The function of all alarms may be reviewed from
the alarm summary menu - see 6.3.5.1.
6.3.6 Display
6.3.6.1 Settings
The backlight brilliance and display contrast are
adjustable from this sub-menu.
6.3.6.2 Quick Access
This sub-menu enables the Quick Access Menu
which is described in sections 2.1 and 6.4 When
enabled, an operator can adjust the display
contrast and backlight brilliance without having
access to any other conditioning menus.
6.3.6.3 Access Code
Defines a four digit alphanumeric code that must
be entered to gain access to the Quick Access
Menu. Alpha characters are case sensitive.
Default code 0000 allows direct access without a
code.
6.3.6.4 Status Text
The two single variable screens 1 and 4 will show
the status of the PROFIBUS variable as ‘Good’ or
‘Bad’ if the Status Text function is activated.
6.3.6.5 Last Input
This function allows the maximum number of
PROFIBUS variables to be defined so that unused
inputs are skipped when the display is scrolled in
the operating mode.
6.3.7 Keys
The function of the front panel push buttons may
be transferred to four of the six optional external
push buttons, with or without disabling the
BA488CF-P front panel push buttons. The table
below shows the function of the BA488CF-P front
panel and the external push buttons for each of the
four options that may be selected in the Keys sub-
menu.
* Apart from when ‘Internal+Port’ is selected, the Key_Status
does not function when the instrument is in the configuration
menu.
The fourth option ‘Internal + Port’ allows the front
panel push buttons to be used for controlling the
BA488CF-P PROFIBUS display and the optional
external push buttons to independently enter
operator acknowledgements or controls. This
option also allows the status of plant mechanical
switches to be returned to the host using the DI
function blocks.
For applications where the instrument is only
displaying 1, 2, 3, 4 or 8 variables on a single
screen, it is recommended that external buttons
are selected but not fitted. This will disable the
instrument front panel buttons, but still provide
access to the configuration menu, which may be
protected by a security code.

6.3.8 Code
Defines the four digit alphanumeric code that must
be entered to gain access to the instrument
configuration menus. Alpha characters are case
sensitive. Default code 0000 allows direct access
without a code.
6.3.9 Unit Info
Displays the instrument model number and the
software version.
6.3.10 Defaults
This function enables the display and interface
board factory defaults to be restored.
6.3.10.1 Display Defaults
This function restores the display defaults defined
in section 6.1. CAUTION
Existing settings can not be recovered
after this function has been used.
6.3.10.2 Interface Board Defaults
This function restores the Fieldbus Interface Board
factory defaults.
CAUTION
Do not use this function when the
BA488CF-P is connected to an
operational PROFIBUS network, as
communication to the display will be
terminated.
6.3.11 Instrument address
Enables the required three digit PROFIBUS
address to be entered digit by digit using the
instrument’s push buttons.
6.4 Quick Access Menu
The Quick Access Menu allows an operator to
adjust the backlight brilliance and the display
contrast without having access to the other
configuration parameters.
The quick access menu is accessed by operating
the Pand ▲push buttons simultaneously. If the
Quick Access Menu is not protected by an access
code the contrast and brilliance controls will be
displayed immediately. If an access code other
than the default code 0000 has already been
entered, the BA488CF-P PROFIBUS display will
request that the access code be entered.
The display backlight brilliance is adjusted using
the ▼and ▲push buttons. Operating the Ppush
button will transfer control to the display contrast
adjustment. When both are set as required,
operating the Ebutton will store both settings and
return the instrument to the operating mode.

7.2 Fault finding after commissioning
ENSURE PLANT SAFETY BEFORE
STARTING MAINTENANCE
Live maintenance is permitted on
intrinsically safe equipment installed in a
hazardous area, but only certified test
equipment should be used unless a gas
clearance certificate is available.
If a BA488CF-P fails after it has been functioning
correctly, the table shown in section 7.1 may help
to identify the cause of the failure.
If this procedure does not reveal the cause of the
fault, it is recommended that the instrument is
replaced.
7.3 Servicing
We recommend that faulty BA488CF-P Fieldbus
Displays are returned to BEKA associates or to our
local agent for repair.
7.4 Routine maintenance
The mechanical and electrical condition of the
instrument should be regularly checked. Initially
annual inspections are recommended, although
the inspection frequency should be adjusted to suit
the environmental conditions.
7.5 Guarantee
Instruments which fail within the guarantee period
should be returned to BEKA associates or our local
agent. It is helpful if a brief description of the fault
symptoms is provided.
7.6 Customer comments
BEKA associates is always pleased to receive
comments from customers about our products and
services. All communications are acknowledged
and whenever possible, suggestions are
implemented.

For installations in the USA, the BA488CF-P and
optional alarms have been approved intrinsically
safe and nonincendive by FM Approvals, project
identification 3022546. Copies of the Certificate of
Compliance are available from BEKA associates.
A1.1 Intrinsic safety approval
The BA488CF-P is approved to the FM Class 3610
intrinsic safety standard for use in indoor
hazardous (classified) locations. Installations must
comply with BEKA associates Control Drawing
CI480-17, which is attached to this Appendix,
ANSI/ISA RP12.06.01 ‘Installation of Intrinsically
Safe Systems for Hazardous (Classified)
Locations’ and with the National Electrical Code
ANSI/NFPA70.
The BA488CF-P has a T4 rating at ambient
temperatures up to +60oC and may be used with
the following gases and dusts:
Intrinsic Safety
Division 1 or 2
Class I Group A & B
Group C
Group D
Zone 0, 1 or 2
Class 1 Group IIC
Group IIB
Group IIA
The FM entity parameters are identical to the
ATEX parameters and, like the ATEX certification,
confirm that terminals 1 & 2 of the BA488CF-P
comply with the requirements for a FISCO Field
Device specified in IEC60079-27. The intrinsically
safe circuits shown in Figs 2 and 3 of this manual
may therefore be used for installations in the USA,
providing the fieldbus power supply, terminators,
Zener barriers and galvanic isolators are FM
Approved and comply with BEKA associates
Control Drawing CI480-17. The FM Approval also
allows the BA488CF-P to be connected to non-
FISCO systems using the entity concept – see
section 4.2 of this manual.
A1.2 Nonincendive approval
The BA488CF-P is Class 3611 nonincendive
approved by Factory Mutual allowing it to be
installed in Division 2 indoor hazardous (classified)
locations without the need for Zener barriers or
galvanic isolators. Installations must comply with
the BEKA associates Control Drawing CI480-18,
which is attached to this Appendix, and with the
National Electrical Code ANSI/NFPA70.
The FM Nonincendive Approval also allows the
instrument to be connected to any FNICO
compliant fieldbus segment powered by FM
Approved Associated Nonincendive Field Wiring
Apparatus.
The BA488CF-P has a T4 rating at ambient
temperatures up to +60oC and may be used with
the following gases and dusts:
