English - Honeywell SEARCHLINE EXCEL PLUS Mode D'emploi

Searchline Excel™ Plus is a 3
(OPFGD) designed to detect and alert to the presence of a range of flammable hydrocarbon gases.
Searchline Excel Plus is an advanced OPFGD detector for Safety applications with coverage from 2 m
to 120 m (6 to 393 ft) range. Searchline Excel Plus Flammable Hydrocarbon Gas Detector consists of a
cooperative transmitter/receiver pair that detects the presence of a range of flammable hydrocarbon gases
in the line between them. Searchline Excel Plus delivers unbeatable uptime with robust detection in the
harshest conditions, penetrating even the thickest fog. It comes with mounts and sunshades as a complete
system and is supported by alignment and test accessories.
Searchline Excel Plus provides local visual status indication as well as 4–20 mA with HART® and Modbus®
outputs as standard. It has a Bluetooth® interface for configuration and maintenance using the Honeywell
Fixed Platform App on a suitable Bluetooth–enabled device.
Searchline Excel Plus 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 or Class III Division 1
locations.
Searchline Excel Plus is available in painted stainless steel and has two cable entries for easy wiring with
either M25 or 3/4" NPT options.
WARNINGS
1. The Searchline Excel Plus Open Path Flammable Gas Detector is certified for and intended for use in
potentially hazardous areas. Installation, operation and maintenance of the instrument must meet
requirements on safety and operation in hazardous areas.
2. Installation must be in accordance with the recognized standards of the appropriate authority in the
country concerned. For Europe see EN 60079-14 and EN 60079-29-2.
3. For installations in the UK, the Code of Practice SELECTION, INSTALLATION AND MAINTENANCE
OF ELECTRICAL APPARATUS FOR USE IN POTENTIALLY EXPLOSIVE ATMOSPHERES should be
strictly observed. General recommendations are given in BS EN 60079-14 & IEC 60079-14. Refer
to BS EN 60079-29-2 & IEC 60079-29-2 in the UK or the appropriate local or national regulations.
4. For installations in North America, the national Electrical Code (NFPA 70) or later issues should be
strictly observed.
5. The Searchline Excel Plus Open Path Flammable Gas Detector transmitters and receivers must
be properly earthed to protect against electrical shock and minimise electrical interference. For
electrical installation design considerations refer to chapter 6 Electrical Installation.
6. Operators must be fully aware of the action to be taken if the gas concentration exceeds an alarm
level.
7. Dismantling or repair of equipment should be carried out in the safe area only.
8. Test gases may be toxic and/or combustible. Refer to Material Safety Sheets for appropriate warnings.
9. Do NOT drill holes in any housing as this will invalidate the explosion protection.
10. In order to maintain electrical safety, the instruments must NOT be operated in atmospheres
containing more than 21% oxygen.
11. Ensure that the bolts which secure flame-proof enclosures are fully tightened. The securing bolts
used are made from a special certified grade of steel. Only bolts supplied by Honeywell Analytics
should be fitted for this purpose.
12. Do NOT open the enclosure in the presence of an explosive atmosphere.
13. The transmitter unit contains high voltages when operational. These are discharged when the unit
is removed from its enclosure.
14. The conduit and cable glands fitted to Searchline Excel Plus transmitter and receiver should NOT
be modified. If, however, it becomes necessary to make modifications they must comply with the
relevant national Codes of Practice.
15. The irradiance and power emitted by the Searchline Excel Plus transmitters is less than 5 mW/mm
and 15 mW/mm
