TATEMENT

The Model CAT 200 Continuous Analyzer Transmitter is intended for use as an

industrial process measurement device only. It is not intended for use in medical,

diagnostic, or life support applications, and no independent agency certifications or

approvals are to be implied as covering such applications.

SAFETY SUMMARY

To avoid explosion, loss of life, personal injury and damage to this equipment

and on-site property, all personnel authorized to install, operate and service this

equipment should be thoroughly familiar with and strictly follow the instructions

in this manual. Save these instructions.

If this equipment is used in a manner not specified in these instructions,

protective systems may be impaired.

DANGER is used to indicate the presence of a hazard which will cause severe

personal injury, death, or substantial property damage if the warning is ignored.

WARNING is used to indicate the presence of a hazard which can cause severe

personal injury, death, or substantial property damage if the warning is ignored.

CAUTION is used to indicate the presence of a hazard which will or can cause minor

personal injury or property damage if the warning is ignored.

NOTE is used to indicate installation, operation, or maintenance information which is

important but not hazard related.

Do not operate without dome and covers secure. Servicing requires access to

live parts which can cause death or serious injury. Refer servicing to qualified

personnel. Operating personnel must not remove instrument covers.

For safety and proper performance this instrument must be connected to a

properly grounded three-wire source of power.

WARNING: ELECTRICAL SHOCK HAZARD

July 2000 Rosemount Analytical 748446-AModel CAT 200 Continuous Analyzer Transmitter

WARNING: POSSIBLE EXPLOSION HAZARD

CAUTION: PRESSURIZED GAS

WARNING: PARTS INTEGRITY AND UPGRADES

WARNING: TOXIC GAS

Do not open instrument when energized.

Ensure that all gas connections are made as labeled and are leak free. Improper

gas connections could result in explosion and death.

This unit’s exhaust may contain hydrocarbons and other toxic gases such as

carbon monoxide. Carbon monoxide is highly toxic and can cause headache,

nausea, loss

of consciousness, and death.

Avoid inhalation of the exhaust gases at the exhaust fitting.

Connect exhaust outlet to a safe vent using stainless steel or Teflon line. Check

vent line and connections for leakage.

Keep all tube fittings tight to avoid leaks. See Section 3.3.6 for leak test

information.

Tampering with or unauthorized substitution of components may adversely

affect the safety of this instrument. Use only factory approved components for

repair.

Because of the danger of introducing additional hazards, do not perform any

unauthorized modification to this instrument.

Return the instrument to a Rosemount Analyiical Service office for service or

repair to ensure that safety features are maintained.

This unit requires periodic calibration with a known standard gas. It also may

utilizes a pressurized carrier gas, such as helium, hydrogen, or nitrogen. See

General Precautions for Handling and Storing High Pressure Gas Cylinders at

the rear of this manual.

Model CAT 200 Continuous Analyzer Transmitter

1.1 OVERVIEW

This manual describes the CAT 200 Continuous Analyzer Transmitter.

The CAT 200 is a multi-component, multi-method Continuous Gas Analyzer. Its Class

I, Zone I (IIB) + H

2

approved enclosure makes it suitable for installation in hazardous

environments. The field mountable housing design allows the CAT 200 to be mounted

close to the process instead of in a remote shelter. This feature greatly reduces

installation and utility costs while improving process efficiency.

The CAT 200 can continuously measure 1, 2 or 3 components in a single analyzer

using a combination of Non Dispersive Infrared (NDIR/UV/VIS), Paramagnetic

Oxygen, Thermal Conductivity, Electrochemical sensors. The CAT 200 also features

an optional customized sample-handling module.

The CAT 200 offers advanced menu and diagnostic functionality with the ability to

network multiple analyzers in complex process monitor and control systems. The high

speed microprocessor architecture of the CAT 200 makes it capable of ultra low range

measurements for CO and CO

1.2 TYPICAL APPLICATIONS

The CAT 200 Continuous Analyzer Transmitter supports a variety of industry

applications, drawing on more than 40 years of development and process expertise in

sensors, digital signal processing and software technologies. The CAT 200 can satisfy

the most demanding single or multi-component analysis requirements. More than 60

gas components can be measured including:

Carbon Monoxide (CO) Carbon Dioxide (CO
