Permanent magnets are surrounded by magnetic fields. These magnetic fields can disturb and even destroy sensitive electronic measuring devices, but also mechanical watches, credit cards, etc.
Usually a distance of 0.5 m is enough to avoid damages. All sintered permanent magnets are hard and brittle. Hitting of sintered permanent magnets by the magnetic attraction causes splitting into fragments with many sharp edges. This especially occurs with high energy magnets, and can also cause skin bruises by high attraction.
High energy magnets made of rare-earth materials have to be stored dry, otherwise the surfaces would oxidise. Unprotected operation in a humid environment may cause corrosion. Avoid damaging the protective galvanic coating.
A storage in a hydrogen atmosphere destroys these magnets. A demagnetisation is caused when permanent magnet materials have been exposed in a radioactive radiation for a long time.
For air transportation of magnetic material the IA TA instructions have to be observed:
Magnetic fields are not allowed to penetrate the package, if necessary the magnets have to be shorted using a metal plate.

SAFETY INSTRUCTIONS
ELECTROSTATIC DISCHARGE
Instruction Manual
Electrostatic Discharge
The electronic parts of the analyzer can be irreparably damaged if exposed to electrostatic discharge (ESD). The instrument is ESD protected when the covers have been secured and safety precautions observed. When the housing is open, the internal components are not ESD protected anymore.
Although the electronic parts are reasonable safe to handle, you should be aware of the following considerations:
90002929
07/2006
Best ESD example is when you walk ed across a carpet and then touched an electrical grounded metal doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).
You prevent ESD by doing the following: Remove the charge from your body before opening the housing and maintain during work
with opened housing, that no electrostatic charge can be built up. Ideally you are opening the housing and working at an ESD - protecting workstation.
Here you can wear a wrist trap.
Howev er , if you do not hav e such a workstation, be sure to do the following procedure exactly: Discharge the electric charge from your body. Do this by touching a device that is grounded
electrically (any device that has a three - prong plug is grounded electrically when it is plugged into a power receptacle). This should be done several times during the operation with opened housing (especially after leaving the service site because the movement on a low conducting floors or in the air might cause additional ESDs).

PREFACE
Preface
a) Analyzer versions - Standard General Purpose Applications
The ML T series of NGA 2000 analyzers offers multi-component, multi-method analysis. Different measurement methods can be combined in one analyzer.
MLT 1, MLT 2 and ML T 4 (MLT 5) are designed to measure up to 5 gas components while ML T 1 ULCO, MLT 3 and CAT 200 allow up to 4 gas components (including photometer and non­photometer channels).
For MLT (MLT 1, 2 & CAT 200) with Foundation Fieldbus (FF) a special FF instruction manual is provided.
NGA 2000 ML T 1 ULCO gas analyzer is specially designed to measure ultra low carbon monoxide. The analyzer is equipped with a 2
nd
optical bench including a multi detector assembly (MDA block) for cross interf erence compensation in automotive and flue gas applications. W ater vapor and carbon dioxide measurement is used for internal cross interference compensation thus providing an ultra low CO and CO2 channel as standard. This solution is designed for automotive (Internal Combustion Engine Emissions, ICEE) and Continuous Emissions Monitoring Systems (CEMS). An additional CO
channel is available as option on automotive applications.
high
For gas purity measurement new quality standards require ultra low CO measurement but not such high dynamic ranging and cross compensation. Therefore the 2nd bench (MDA) is not used, b ut another channel, e.g. ultra low carbon dioxide (ULCO2) can be implemented in ML T 1.
All ML T 2 components are incorporated into a wall-mountable housing with ingress protection code IP 65 (designed to meet NEMA 4/4X) according to EN 60529. This housing is equipped with an impact tested front panel according to EN 50014 operated by a magnetically operated touch panel. The MLT 2 can be purged to remove corrosive or toxic gases with synthetic air or instrumental air (dry, free of oil, hydrocarbons and corrosive components; 20 to 35 °C purge gas temperature). If sample gas contains flammable gas components above the lower explosion limit, the required explosion protection measures (purge/pressurization system) must be approved b y an authorized person (ATEX/CSA-C/US purge system) . ML T 2 is available with a dual compartment enclosure, too, whereat electronics and photometer/ sensors are installed in two separate housings. Special high temperature variations of MLT 2 or 3 for physics temperatures up to 120 °C are optionally available (standard thermostat control: 55 °C; 65 °C as option). Special versions of MLT 3 are available with suppressed r anges for gas purity measurements and a corresponding additional manual too (special sample handlingrequirements).

b) Analyzer versions - Installation in Hazardous Areas
Note!
This manual does not deal with special conditions for analyzers in hazardous areas , related to installation, operation, maintenance etc. For such applications refer to the separate instruc-
tion manuals, delivered together with the analyzers.
For installation in hazardous areas the ML T 2 can be equipped with the appropriate pressurization system acc. to the actual required explosion protection measures.
Solutions acc. to CENELEC (according to former European EN 50016) use combinations of ML T 2 and an appropriate pressurization system being individually certified (see separate manual about pressurization system and individual certification report - §10 Elex). In this case a magnetically operated touch panel or an intrinsically safe front panel (combined with approved PCB EXI 01for Zone 1, option for Zone 2) is implemented and ML T 2 is combined with a simplified pressurization for European Ex Zone 2 or with an approved pressurization system for European Ex Zone 1 (see separate instruction manual). Additionally the MLT 2 may be equipped with intrinsically safe I/O's (see separate instruction manual )
ML T 2-NF is a special analyzer version of ML T 2 with Z Purge system for North American Class 1 Zone 2 measurements of non-flammable gases in hazardous areas (CSA-C/US type approved for Zone 2, see separate instruction manual).
EEx p solutions acc. to ATEX (European Directive for Equipment to be used in Explosive Atmospheres; mandatory since July 1, 2003) use type approv ed combinations of MLT 2 and appropriate pressurization systems (see separate A TEX instruction manual about pressurization system and certification). The separate A TEX manual covers all EExp Ex Zone 1 solutions as well as solutions for Ex Zone 2 measuring non-flammable gases. Solutions for measuring flammable gases in Ex Zone 1 or 2 are described in a separate instruction manual. For installation acc. to ATEX in Ex Zone 1 and 2 the MLT 2 is always equipped with a magnetically operated touch panel (see separate manual too). Additionally the MLT 2 may be equipped with intrinsically safe I/O's (see separate instruction manual).
The CA T 200 analyzer or analyz er module is designed to be installed in hazardous areas, too, It is consisting of a 1/2-19" ML T 1 analyz er (analyzer module) installed into a flameproof Ex d enclosure with Ex em junction box. This model is CSA-C/US and ATEX approved for installation in North-American and European hazardous areas (Ex zone 1).

c) Analyzer System Architecture
The ML T´s flexibility facilitates the most cost-effective system architecture - elegantly accommo­dating either “stand-alone” or integrated multi-channel analyzer requirements. The ML T is availab le both as an “Analyzer Module” or as an “Analyzer”.
The “Analyzer Module” (AM) is a “b lind” analysis unit but retains all the adv anced MLT design features. The AM variant is designed for integration as part of a Multiple NGA 2000 analysis system or special customer developed networks. The MLT AM novel “blind” packaging and network functionality allows the user to easily exploit the ML T analyser´s advanced expansion capability.
The MLT Analyzers can be designed as single stand-alone analyzers - complete with control module functionality and front panel display/operator interface - or as an centr al interf ace f or multiple Analyzer Modules with a network board.
In ML T analyzer systems this feature eliminates duplication of the displa y/operator interface. In addition to the obvious operational benefits, MLT Analyzers offer significant cost and system packaging advantages not possible with conventional analyser configurations. This flexible network communication architecture is shown in Fig. P-4.
