OELD Op erating Inst ructions

2 Overview

2.1 Introduction

OELD is hazardous location certiﬁed junction box for use with sensors that feature a 420 mA output. The OELD unit has been designed to operate with the Searchpoint Optima Plus or Searchline Excel range of gas detectors. It provides a local visual status indication, and a Bluetooth® low energy interface for conﬁguration and maintenance using a Bluethooth®-enabled mobile device. The OELD unit is ATEX and IECEx approved for use in either Zone 1 (gas) or Zone 21 (dust) hazardous areas as well as being cULus approved for use in Class I Division 1 or Class II Division 1.

The OELD unit has ﬁve entries – either M25 or 3/4” NPT (dependent on the version) and is supplied with three certiﬁed blanking plugs.

WARNING

The plastic transport caps supplied must be replaced with a sensor or suitably certiﬁed closers (such as glands or stopping plugs) prior to commissioning the OELD. Failure to do so presents a potential source of ignition.

Internally, the enclosure features two earth connection points, and an electronics module with two pluggable terminal blocks for connection of ﬁeld and sensor wiring. The OELD features a four-color backlight (green, yellow, red and blue), and a custom 7-segment liquid crystal display (LCD). In operation, the LCD backlight provides a status indication as follows:

• Green – Normal operation or Warning

• Yellow – Fault or Inhibit

• Red – Alarm (level is configurable)

• Blue – Bluethooth® pairing / connection

Refer to section 6.1.2 Normal Operation for full details on this feature.

WARNING

Do not rely on the OELD LCD backlight status indication for safety-related purposes.

The OELD is conﬁgured using a mobile device (such as smart phone or tablet) over Bluetooth® Low Energy. The following parameters can be conﬁgured:

• Threshold for local alarm notification (red indication)

• 420 mA operational levels for the local display

• Gas name, measurement units and range for local display

• Additionally when using the OELD in conjunction with a Searchpoint Optima Plus or Searchline Excel, the user will be able to gain

full access to all configuration and maintenance parameters of the gas detector.

2.2 Optional Accessories

Note

The optional pipe mount, ceiling bracket and sunshade accessories are not included as part of the assessment to EN60079291.

2.2.1 Pipe Mount Kit (1226A0358)

The Pipe Mount kit (1226A0358) allows the OELD to be mounted to pipe from 2” to 6” (50 to 150 mm) in diameter. The kit includes the pipe mount bracket, two carriage bolts, nuts, and lock washers.

2.2.2 Ceiling Mount Bracket Kit (1226A0355)

The Ceiling Mount Bracket Kit (1226A0355) allows the OELD to be mounted to the ceiling. The kit includes two stainless steel ceiling mount brackets, bolts, and nuts.

Note

When considering the ﬁnal mounting position using the Ceiling Mount Bracket Kit, consider the ability to see the OELD display when installed.

2.2.3 Sunshade (94000A1006)

SEARCHPOINT OPTIMA PLUS C /W SUNSH ADE AND FI TTED TO THE OELD

A sunshade manufactured from 316 stainless steel, is available which covers the OELD and can extend over either side to also provide protection to a Searchpoint Optima or Searchline Excel

The sunshade slots over the OELD mounting bolts so no additional ﬁxings are required and is stainless steel 316.

Use the sunshade to reduce the effects of direct solar heating.

3 Installation

3.1 Siting and Positioning

The placement of gas detectors should be determined following the advice of:

• experts having specialist knowledge of gas dispersion

• experts having knowledge of the process plant system and equipment involved

• safety personnel

• engineering personnel

The agreement reached on the location of detectors should be recorded.

Guidance on the positioning of gas detectors to provide the best detection coverage is contained in IEC/EN 60079292 and other national Codes of Practice. It is recommended that the installation designer consults these Codes of Practice when determining where detectors are to be located.

Additionally refer to the technical manual of the gas detector for siting recommendations speciﬁc for that device.

3.2 Mechanical Installation

The OELD can be mounted in a number of ways using the integral mounting tabs. The OELD can be attached to ﬂat wall surfaces or to Unistrut®. With the optional Pipe Mount kit, the unit can be mounted to pipe or pole. A ceiling mount bracket kit (1226A0358) is also available. If required, conduit (either ﬂexible or rigid) can be run to the OELD.

3.2.1 Installation to a Flat Surface

The OELD may be ﬁxed directly to a suitable ﬂat surface, using the integral mounting points (dimensions shown below).

Note

When installing OELD ensure that the correct sensor orientation is considered. Refer to the sensor manufacturer’s instructions.

Ensure that mounting bolts are fully tightened and suitable locking washers are used.

3.2.3 Using the Searchline Excel Mounting Plate

The OELD may be ﬁxed to the Searchline Excel mounting plate (2104D0237), which is included in the Searchline Excel kits. Two M10 tapped holes, ‘K’, are provided for mounting the OELD. Refer to the Searchline Excel technical manual for other details. The mounting plate ﬁxings are not supplied.

Always mount plate this way up

3.3 Electrical Installation

1. Remove the lid.

2. Lift the handle and take out the electronics module.

3. Fit a suitably approved cable gland or conduit fitting to the required cable entry for the field cable.

4. Fit a sensor to the desired entry referring to the sensor manual for specific information and recommended detector orientation). Use sealing washers where necessary to maintain the ingress protection rating to IP66/67.

5. Fit suitably certified stopping plugs to all unused cable entries. Use sealing washers where necessary to maintain the ingress protection rating to IP66/67.

WARNING

The plastic transport caps supplied must be replaced with suitably certiﬁed closers (such as glands or stopping plugs) prior to commissioning the OELD. Failure to do so presents a potential source of ignition.

6. Make the electrical connections (see Chapter 4).

7. Carefully replace the electronics module.

8. Replace and tighten the cover and tighten the locking screw.

Caution

Take care to avoid trapping cables when replacing the display module.
