INTRODUCTION
The BA3200 series plug-in CPU (Central Processing Unit) modules are part of the BEKA Pageant Display System. The following models are available, one with external communication:
- BA3201 CPU module without communication
- BA3202 CPU module with RS485-IS communication
All models have IECEx, ATEX and UKCA intrinsic safety apparatus certification.
Fig 1 shows a BA3200 CPU plug-in module with its features identified. It
contains a central processor and a removable micro SD card on which is stored
the Linux operating system, CODESYS™ runtime programme and the PLC application
programme. The CPU module plugs into the ‘C’ socket at the rear of the BA3101
Pageant Operator DisplayPower for the BA3101 Operator Display and up to seven
plug-in input and output modules is distributed via the CPU module from a BEKA
Power Isolator in the safe area or Zone 2.
The BA3200 series CPU modules and all of the plug-in input and output modules
have individual intrinsic safety apparatus certificates. Compatible input and
output safety parameters allow any certified BEKA Pageant CPU module to be
fitted in the Pageant Operator Panel ‘C’ socket without any additional
certification.
INTRINSIC SAFETY CERTIFICATION
Notified Body CML B.V. and UK Approved Body Eurofins CML have issued the BA3200 series plug-in CPU modules with the following apparatus certificates:
IECEx IECEx CML 20.0152X
ATEX CML 20ATEX2254X
UKCA CML 21UKEX2005X
The ATEX certificate has been used to confirm compliance with the European ATEX Directive for Group II, Category 1GD equipment, similarly the UKCA certificate has been used to confirm compliance with UK statutory requirements. All BA3200 series CPU modules carry both the CE and UKCA marks, subject to local codes of practice, they may be installed in any of the European Economic Area (EEA) member countries and in the UK. ATEX certificates are also acceptable for installations in some non EU countries. These instructions describe IECEx, ATEX and UKCA installations which conform with IEC / EN 60079-14 Electrical installations design, selection and erection. When designing systems the local code of practice should be consulted.
Plug-in BA3200 series Pageant CPU Modules are CE marked to show compliance
with the European Explosive Atmospheres Directive 2014/34/EU and the European
EMC Directive 2014/30/EU.
The modules are also UKCA marked to show compliance with UK statutory
requirements Equipment and Protective Systems Intended for Use in Potentially
Explosive Atmospheres Regulations UKSI 2016:1107 (as amended) and with the
Electromagnetic Compatibility Regulations UKSI 2016:1091.
Zones, gas groups and T rating
All of the BA3200 series CPU certificates specify the same code:
- Dust certification requires the Pageant Operator Display and the BA3200 series CPU module to have IP54 rear protection.
Intrinsic safety parameters for power input terminals TB1:
Powering a BA3200 series CPU module
The BA3101 Pageant Operator Display and all of the plug-in modules are powered
via the BA3200 series CPU modules TB1 terminals. The intrinsic safety input
parameters of these terminals match the output parameters of a BEKA BA212
Power Isolator. This allowing direct connection between the two for
applications in gas groups IIA and IIB and in dust hazardous atmospheres. For
most applications in a IIC gas hazardous atmosphere a BEKA BA243 Power
Isolator should be used. This has four galvanically isolated intrinsically
safe outputs which are remotely combined by a certified BA3901 4 way Power
Combiner allowing longer field cables to be used. The intrinsic safety
parameters of the four BEKA BA212 outputs match the input parameters of the
CPU module and power combiner allowing a direct connection between the two.
For further information about maximum permitted cable lengths please see the
Pageant System Operator Panel Instructions and the BEKA Application Guide
AG210.
Special conditions for safe use
All three CPU apparatus certificate numbers have an ‘X’ suffix indicating that
the following special conditions apply, please see certificates for full
details:
-
Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this equipment may generate an ignition-capable level of electrostatic charge. Therefore, the equipment shall not be installed in a location where the external conditions are conducive to the build-up of electrostatic charge on such surfaces. In addition, the equipment shall only be cleaned with a damp cloth.
-
In installations requiring EPL Da, Db, or Dc, the equipment shall be mounted to an enclosure which provides a minimum degree of protection of IP5X and which meets the requirements of EN60079-0 Clause 8.4 (material composition requirements for metallic enclosures for GroupIII) and/or EN60079-0 Clause 7.4.3 (Avoidance of a build up of electrostatic charge for Group III) as appropriate.
All cable entries into the equipment shall be made via cable glands which provided a minimum degree of protection of IP5X. -
The equipment shall only be connected to programming equipment via SK2 when in the safe area and shall only by connected via the galvanically isolating interface unit provided by the manufacturer. (BA3902 Programming Cable)
RS485-IS communications
The BA3202 plug-in CPU module include an RS485-IS communications port. This is
a galvanically isolated intrinsically safe port complying with the physical
layer requirements specified by the Profibus RS 485-IS User and Installation
Guideline, version 1.1.
The port has the following safety parameters:
CAUTION
When the port is fitted with a sub D9 male or BA3903 connector, the bus cable
must be supported to prevent vibration damage to the connectors.
Certification label information
The certification information label is fitted to the side of the BA3200 series
plug-in CPU module. It shows the model number, certification information, BEKA
associates address and year of manufacture together with the serial number
NSTALLATION
The BA3200 series plug-in CPU module should be fitted into the ‘C’ socket of a BA3101 Pageant Operator Display as shown in Fig 2.
For a hazardous area installation the plug-in CPU module must be manufactured by BEKA and have certification that specifies that it should be used with a BEKA Pageant system
BA3200 series plug-in CPU Installation
- The BA3200 series CPU module may be fitted before or after the Operator Display is installed, but the CPU module should not be powered while being added or removed.
- Carefully insert the CPU module into the ‘C’ socket at the rear of the Pageant BA3200 series Operator Display as shown in Fig 2. When correctly positioned secure the assembly by tightening the two module fixing screws.
- For applications in a IIA or IIB flammable gas atmosphere or in a combustible dust atmosphere, connect a twisted pair instrument cable between terminals TB1 on the CPU module to a BA212 Power Isolator located in a safe area or Zone 2.
For most applications in a IIC gas atmosphere mount a BA3901 4 way Power Combiner on the rear of the CPU module and connect its terminals to a BA243 Power Isolator located in a safe area or Zone 2 with four twisted pair instrument cables.
For detailed information about types of cables and maximum permitted lengths see Pageant Operator Panel System instructions and BEKA Application Guide AG210.
MAINTENANCE
The BA3200 series CPU module should be regularly inspected to ensure that it
has not been damaged. The frequency of inspection depends upon environmental
conditions.
No attempt should be made to repair a faulty BA3200 series plug-in CPU module.
Suspect modules should be returned to BEKA associates or your local BEKA
agent.
Transferring a PLC application file to Pageant
After a new or modified PLC application file has been developed within a
CODESYS Integrated Development Environment (IDE) it can be transferred to the
Pageant Operator Panel in a number of ways.
The easiest and fastest technique is to unplug the CPU module from the Hazardous area Pageant Operator Panel and remove the micro SD card as shown in Fig 3
Fig 3 Removing micro SD card from plug-in CPU module
Using an SD card writer the revised compiled PLC application code can be copied to the micro SD card in a safe area. A Windows based system will show 4 removable drives on the SD card:
- Kernel
- Unknown Format
- Unknown Format
- BEKA
The compiled PLC application file should be copied to the User Program Update
area. Additional information about transferring compiled PLC application files
is contained in the Pageant Operator Panel System instructions.
After the revised compiled PLC application file has been copied to the SD
card, the card should be replaced in the CPU module and the module reinstalled
in the Pageant Operator Panel.
Alternatively, if a duplicate Pageant Operator Panel is available in a safe area, the hazardous area Operator Panel CPU module should be transferred to the safe area Pageant Operator Panel. Using a BA3902 Programming Cable to connect a USB port on the PC hosting the CODESYS IDE to the programming port on the CPU module, the compiled updated PLC application file can be copied to the CPU module. Finally, the CPU module should be transferred back in the hazardous area Pageant Operator Panel.
The BA3902 Programming Cable shown in Fig 4 ensures that the intrinsic safety
components within the CPU module are not damaged if a fault develops in the
PC.
When installing or removing a plug-in CPU module in a Pageant Operator
Display, the CPU module should not be powered.
Fig 4 Transferring PLC application file to Pageant in a safe area
If a gas clearance certificate is available for the hazardous area in which the Pageant Operator Panel is installed, method b can be used to transfer the compiled PLC application file directly to the CPU module in hazardous area Pageant Operator Panel.
CAUTIONS
Unless a gas clearance certificate is available, BA3200 series CPU modules
should only be reprogrammed in a safe area.
A BEKA BA3902 CPU Module Programming Lead should be used to connect the
programming port to the programming computer.
GUARANTEE
BA3200 series CPU modules which fail within the guarantee period should be returned to BEKA associates or your local BEKA agent. It is helpful if a brief description of the fault symptoms is provided.
