Particular Specifications for use in Explosive Atmospheres in Accordance with
the European ATEX 94/9/EC Directive.
The
MX 15
detection controller intended for the measurement of explosive
gases, conforms to European ATEX Directive (94/9/CE) pertaining to
explosive atmospheres.
The
MX 15
detection controller is certified in accordance with EN 61779-1 and
EN 61779-4 (metrological performance) as a safety device for ATEX Zone 2.
The controller can also reduce the risk of explosion by sending data to outside
units.
Information in following paragraphs must be taken into account and followed
by the person responsible for the equipment installation site. Refer to the
provisions of European ATEX Directive 1999/92/EC, concerning the
improvement of safety protection and the health of workers exposed to the
risks of explosive atmospheres.
Specifications for mechanical and electrical
installations in Explosive Zones.
All installations must be in compliance with currently enforced standards,
notably standards EN 60079-14 and EN 60079-17.
The
MX 15
controller must not be subject to intense mechanical vibration and
must be installed
in a safe area away from explosive atmospheres.
It is very important to refer to the user and start-up manuals for the gas
detectors being used.
Metrological specifications
The controller conforms to European metrological standards EN 61779-1 and
EN 61779-4 for methane (calibration gas), butane, propane and hydrogen
(gasses which follow response curves), where the controller is used with
Oldham
gas detectors as stated in the EC Declaration of Conformity (Chapter
6).
Where the controller is used with other types of detectors delivering a current
of 4-20 mA, they must conform to ATEX Directive 94/9/EC, Annex II,
paragraph 1.5 and be compatible with the characteristics described therein
(refer to the controller transfer curve) in Figure 9.
Note: the vibration tests described in EN 61779-4 paragraph 4.13 were not
performed and therefore are not applicable for the operating conditions for the
MX 15
controller.
