ATEX Compliance Information
1 Introduction and Description of Equipment.
HotSpotIR Ex for Zone 22 is a special version of the Land LSP series Linescanner
which has been certied for use in a potentially explosive Dust atmosphere. It
uses the concept of Protection by Enclosure (tD) as dened in the European
standards EN 61241-0:2006 & EN 61241-1:2004.
The equipment is certied as Category 3D for use in hazardous dust zone 22.
• Always quote the model number and the serial number in any
correspondence or when ordering spare parts etc.
To achieve the level of protection required for Ex tD, HotSpotIR Ex models have
been modied to incorporate a connector retaining clamp and the heads are
supplied with an integral water cooled/air purged mounting plate that provides
protection for the window. The equipment must not be dismantled or any covers
removed when an explosive atmosphere may be present.
The equipment must not be modied in any way. For all repair issues, contact
Land Instruments International. Repair of this equipment shall be carried out by
suitably trained and authorized personnel in accordance with the applicable code
of practice.
The equipment has not been assessed as a safety related device (as referred to
by Directive 94/9/EC Annex II, clause 1.5).
Installation and inspection of this equipment shall be carried out by suitably
trained and authorized personnel in accordance with the applicable code of
practice.
The equipment shall be installed such that the supply cable is protected from
mechanical damage.
The certication of this equipment relies on the following materials used in its
construction:
Enclosure: Aluminium Alloy (<7.5% total Magnesium and
Aluminium)
Connector o-ring: Viton
Enclosure o-ring: Nickel/Graphite loaded Silicone elastomer
Window o-ring: Silicone rubber
Window cement: Loctite 350 UV cured
If the equipment is likely to come into contact with aggressive substances,
then it is the responsibility of the user to take suitable precautions that
prevent it from being adversely affected, thus ensuring that the type of
protection is not compromised.
“Aggressive substances” - e.g. acidic liquids or gases that may attack
metals, or oils and solvents that may affect polymeric or elastomeric
materials.
“Suitable precautions” - e.g. regular checks as part of routine inspections
or establishing from the material’s data sheet that it is resistant to specic
chemicals.
