Beka Ba3101 User manual

1. INTRODUCTION

The BA3101 is an IECEx, ATEX and UKCA certied

intrinsically safe Operator Display. It is the core of the

Pageant Operator Display System comprising a 7 inch

backlit display with 8 touch buttons plus 8 sockets which

can accommodate a single CPU module and up to 7 input

and output modules.

The Operator Display and all of the plug-in modules are

powered from a BEKA Power Isolator in the safe area or

Zone 2 via a plug-in CPU (Central processing unit) module.

The CPU module can also have external communications.

Fig 1 shows the rear of the BA3101 Pageant Operator

Panel with its features identied.

The BA3101 and all of the plug-in modules have individual

intrinsic safety apparatus certicates. Compatible input

and output safety parameters allow any certied BEKA

plug-in Pageant CPU module to be tted in display socket

‘C’. Similarly, any certied BEKA plug-in Pageant input or

output module may be tted into sockets 1 to 7, providing

the sum of the percentage power consumption of all the

modules tted does not exceed 100%. See Pageant

System Operator Panel instructions for further details.

Apart from an earth stud, all eld connections to the

BA3101 Pageant Operator Display are made via removable

terminals on the plug-in modules.

The BA3101 Pageant Operator Display is CE marked to show compliance with the European Explosive

Atmospheres Directive 2014/34/EU and the European EMC Directive 2014/30/EU.

The BA3101 is 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.

2.1 Gas atmospheres - Zones, gas groups and T rating

All of the BA3101 Operator Display certications specify

the same gas code:

Ex ia IIC T4 Ga -40°C ≤ Ta ≤ 65°C

The Operator Display has no external connections, the

only input and output intrinsic safety parameters are for

the plug-in modules. It is therefore only necessary for the

specier and installer to ensure that all the plug-in modules

are manufactured by BEKA and are certied for use with a

BA3101 Pageant Operator Display.

When tted with a certied BEKA plug-in CPU module

and certied BEKA plug-in input and output modules, the

BA3101 may be installed in:

Zone 0 explosive gas air mixture

continuously present.

Unlikely requirement

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

In gases that may be used with equipment having a

temperature classication of:

T1 450°C

T2 300°C

T3 200°C

T4 135°C

At an ambient temperature Ta between -40°C and +65°C

2.2 Dust atmospheres - Zones

All of the BA3101 Operator Display certications specify

the same dust code:

Ex ia IIIC T135°C Da -40°C ≤ Ta ≤ 65°C.

For applications in dust atmospheres, the certicates

specify Special Conditions of Use (See section 2.3) which

require the rear of the Operator Panel to have additional

protection. This requirement can be satised by mounting

the BA3101 Operator Display in a component certied

Ex e enclosure with cable glands providing a minimum

IP5X sealing.

When tted with a certied BEKA plug-in CPU module

and certied BEKA plug-in input and output modules, the

BA3101 may be installed in:

Zone 20 explosive atmosphere in the form of a cloud

of combustible dust in air is continuously

present, or for long periods or frequently.

Zone 21 explosive atmosphere in the form of a cloud

of combustible dust in air is likely to occur

occasionally in normal operation.

Zone 22 explosive atmosphere in the form of a cloud

of combustible dust in air is not likely to occur

in normal operation, but if it does occur, will

only persist for a short period.

Be used with dust in subdivisions:

IIIA combustible yings

IIIB non-conductive dust

IIIC conductive dust

2.3 Special conditions for safe use

All three certicate numbers have an ‘X’ sufx indicating

that special conditions apply, please see certicates.

i. Under certain extreme circumstances, the non-

metallic parts incorporated in the enclosure of this

3. INSTALLATION

3.1 Location

The BA3101 Pageant Operator Display has a 316 stainless

steel front panel surrounding the backlit display which is

protected by a 4mm thick toughened glass window. The

front of the Operator Display has IP66 protection and a

silicone moulded gasket provides an IP66 seal to the

instrument panel. The rear of the BA3101 Pageant

Operator Display has IP20 protection.

The BA3101 may be installed in any panel providing the

environmental and safety limits shown in the specication

are not exceeded. Although the front of the Operator

Display has IP66 protection, it should be shielded from

continuous direct sunlight and severe weather conditions.

Fig 2 shows the overall dimensions of the BA3101 including

the plug-in modules and the panel cut-out.

3.2 BA3101 Operator Display Installation Procedure

1. Cut the aperture specied in Fig 2 in the panel and

ensure that all edges are de-burred.

2. First ensure that all eight panel mounting clamps

are closed by turning the knurled screws fully

anticlockwise until the two pips in the clamp foot

align with holes in the clamp body as shown in

Fig 3.

3. Ensure that the panel sealing gasket is correctly

positioned before inserting the BA3101 Operator

Display into the panel aperture.

4. Place a clamp in the recess on each side of the

BA3101, pulling gently to slide it onto the dovetail

as shown in Fig 3. Push the knurled screw slightly

forward to engage the thread and tighten by turning

clockwise until it is just nger tight. When both

clamps are tted ensure that the gasket behind

the front panel bezel remains correctly positioned

before tting the remaining panel mounting clamps.

Finally, fully tighten all the panel clamps to secure

the instrument. The maximum recommended clamp

tightening torque is 22cNm (1.95 lbf in) which is

approximately equivalent to nger-tight plus one

half turn. Do not over tighten.

Insert panel clamp into

recess and gently pull it onto

the dovetail. Engage screw

4. PLUG-IN MODULES

The BA3101 Operator Panel can accommodate one plug-

in CPU module in the right hand socket, marked ‘C’ and up

to seven plug-in input or output modules in the remaining

sockets marked 1 to 7 as shown in Fig 1. Modules have

keyed plugs and sockets which ensure that an input or

output module can not be tted in the ‘C’ socket and a

CPU module can not be tted in sockets marked 1 to 7.

All BA3101 Operator Displays must be tted with a plug-in

CPU module which contains the central processing unit

and memory. It also distributes power to the display and

to all of the plug-in input and output modules from a BEKA

Power Isolator located in the safe area or in Zone 2. Some

CPU modules also include an external communication

port.

Input and output modules may be tted in any of the seven

sockets most convenient for eld wiring, they do not have to

be installed in a specic position or order, but their position

does have to be entered in the application software.

4.1 Installing a plug-in module

All Pageant plug-in modules are installed in the same way

and may be tted before or after the Operator Display is

mounted in a panel or cubicle. The Operator Display

should not be powered while a plug-in module is being

inserted or removed.

For a hazardous area installation plug-in modules must be

manufactured by BEKA and have certication that species

that they shall be used as part of a BEKA Pageant system.

5. FIELD WIRING

All eld connections to the BA3101 Operator Panel are

made via the removable terminals on the plug-in modules

which are described in the instructions supplied with each

module. Apart from the earth stud, there are no direct eld

connections to the BA3101 Pageant Operator Display.

The M4 earth stud is located on the right hand side at the

rear of the Operator Panel as shown in Fig 1. It should

be connected to earth and to the metallic structure of the

enclosure in which the BA3101 Pageant Operator Panel

is mounted.

To simplify installation all module eld wiring terminals are

removable by gently pulling. Wiring should be supported

to prevent damage to the connectors, particularly in

installations subject to vibration.
