Particular Specifications for use in Explosive Atmospheres in Accordance with
the European ATEX 94/9/CE Directive.
The
MX 32
detection controller intended for the measurement of explosive
gases, conforms to European ATEX Directive 94/9/CE pertaining to explosive
atmospheres.
Due to their metrological performances as tested by INERIS (French National
Institute for Industrial Environment and Risks), the
MX 32
paired with
Oldham
CEX 300 and TBGW-EX detectors as well as those in the OLC/OLCT series:
20, 40, 50, 60, 100 and OLCT IR is classified as a safety device. 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, EN 60079-17, and EN 50281-1-2.
The
MX 32
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.
For intrinsically safe installations, the person responsible for the IS
installation, called “the system designer,” must establish a system document
demonstrating that the entire Sensor/Cable/Power Supply system is
Intrinsically Safe. See the EN 50039 standard for group II and the EN 50394-1
standard for group I to prepare this document.
Metrological specifications
The controller conforms with the following European standards.
