THRESHOLD LIMIT VALUE

(See Section III)

EFFECTS OF OVER EXPOSURE

EYE

Avoid contact with eyes. Slightly to moderately irritating. Abrasive action may cause damage to outer surface

of eye.

INHALATION

May cause respiratory tract irritation. Repeated or prolonged breathing of particles of respirable size may cause

inflammation of the lung leading to chest pain, difficult breathing, coughing and possible fibrotic change in the

lung (Pneumoconiosis). Pre-existing medical conditions may be aggravated by exposure: specifically, bron-

chial hyper-reactivity and chronic bronchial or lung disease.

INGESTION

May cause gastrointestinal disturbances. Symptoms may include irritation and nausea, vomiting and diarrhea.

SKIN

Slightly to moderate irritating. May cause irritation and inflammation due to mechanical reaction to sharp, bro-

ken ends of fibers.

EXPOSURE TO USED CERAMIC FIBER PRODUCT

Product which has been in service at elevated temperatures (greater than 1800ºF/982ºC) may undergo partial

conversion to cristobalite, a form of crystalline silica which can cause severe respiratory disease (Pneumoco-

niosis). The amount of cristobalite present will depend on the temperature and length of time in service. (See

Section IX for permissible exposure levels).

SPECIAL TOXIC EFFECTS

The existing toxicology and epidemiology data bases for RCF’s are still preliminary. Information will be up-

dated as studies are completed and reviewed. The following is a review of the results to date:

EPIDEMIOLOGY

At this time there are no known published reports demonstrating negative health outcomes of workers exposed

to refractory ceramic fiber (RCF). Epidemiologic investigations of RCF production workers are ongoing.

1) There is no evidence of any fibrotic lung disease (interstitial fibrosis) whatsoever on x-ray.

2) There is no evidence of any lung disease among those employees exposed to RCF that had never smoked.

3) A statistical “trend” was observed in the exposed population between the duration of exposure to RCF and a

decrease in some measures of pulmonary function. These observations are clinically insignificant. In other words, if

these observations were made on an individual employee, the results would be interpreted as being within the

normal range.

4) Pleural plaques (thickening along the chest wall) have been observed in a small number of employees who had a

long duration of employment. There are several occupational and non-occupational causes for pleural plaque. It

should be noted that plaques are not “pre-cancer” nor are they associated with any measurable effect on lung

function.

TOXICOLOGY

A number of studies on the health effects of inhalation exposure of rats and hamsters are available. Rats were

exposed to RCF in a series of life-time nose-only inhalation studies. The animals were exposed to 30, 16, 9,

and 3 mg/m3, which corresponds with approximately 200, 150, 75, and 25 fibers/cc.

Animals exposed to 30 and 16 mg/m3 were observed to have developed a pleural and parenchymal fibroses;

animals exposed to 9 mg/m3 had developed a mild parenchymal fibrosis; animals exposed to the lowest dose

were found to have the response typically observed any time a material is inhaled into the deep lung. While a

statistically significant increase in lung tumors was observed following exposure to the highest dose, there was

no excess lung cancers at the other doses. Two rats exposed to 30 mg/m3 and one rat exposed to 9 mg/m3 de-

veloped masotheliomas.

The International Agency for Research on Cancer (IARC) reviewed the carcinogenicity data on man-made vit-

reous fibers (including ceramic fiber, glasswool, rockwool, and slagwool) in 1987. IARC classified ceramic fi-

ber, fibrous glasswool and mineral wool (rockwool and slagwool) as possible human carcinogens (Group 2B).

EMERGENCY FIRST AID PROCEDURES

EYE CONTACT

Flush eyes immediately with large amounts of water for approximately 15 minutes. Eye lids should be held

away from the eyeball to insure thorough rinsing. Do not rub eyes. Get medical attention if irritation persists.

INHALATION

Remove person from source of exposure and move to fresh air. Some people may be sensitive to fiber induced

irritation of the respiratory tract. If symptoms such as shortness of breath, coughing, wheezing or chest pain

develop, seek medical attention. If person experiences continued breathing difficulties, administer oxygen until

medical assistance can be rendered.

INGESTION

Do not induce vomiting. Get medical attention if irritation persists.

SKIN CONTACT

Do not rub or scratch exposed skin. Wash area of contact thoroughly with soap and water. Using a skin cream

or lotion after washing may be helpful. Get medical attention if irritation persists.

SECTION VII. SPILL OR LEAK PROCEDURES

STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED

Where possible, use vacuum suction with HEPA filters to clean up spilled material. Use dust suppressant

where sweeping if necessary. Avoid clean up procedure which may result in water pollution. (Observe Special

Protection Information Section VIII.)

WASTE DISPOSAL METHODS

The transportation, treatment, and disposal of this waste material must be conducted in compliance with all ap-

plicable Federal, State, and Local regulations.

SECTION VIII. SPECIAL PROTECTION INFORMATION

RESPIRATORY PROTECTION

Use NIOSH or MSHA approved equipment when airborne exposure limits may be exceeded. NIOSH/MSHA

approved breathing equipment may be required for non-routine and emergency use. (See Section IX for suit-

able equipment).

Pending the results of long term health effects studies, engineering control of airborne fibers to the lowest lev-

els attainable is advised.

VENTILATION

Ventilation should be used whenever possible to control or reduce airborne concentrations of fiber and dust.

Carbon monoxide, carbon dioxide, oxides of nitrogen, reactive hydrocarbons and a small amount of formalde-

hyde may accompany binder burn-off during first heat. Use adequate ventilation or other precautions to elimi-

nate vapors resulting from binder burn-off. Exposure to burn-off fumes may cause respiratory tract irritation,

bronchial hyper-reactivity and asthmatic response.

SKIN PROTECTION

Wear gloves, hats and full body clothing to prevent skin contact. Use separate lockers for work clothes to pre-

vent fiber transfer to street clothes. Wash work clothes separately from other clothing and rinse washing ma-

chine thoroughly after use.

EYE PROTECTION

Wear safety glasses or chemical worker’s goggles to prevent eye contact. Do not wear contact lenses when

working with this substance. Have eye baths readily available where eye contact can occur.

SECTION IX. SPECIAL PRECAUTIONS

PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING

General cleanliness should be followed.

The Toxicology data indicate that ceramic fiber should be handled with caution. The handling practices de-

scribed in this MSDS must be strictly followed. In particular, when handling refractory ceramic fiber in any

application, special caution should be taken to avoid unnecessary cutting and tearing of the material to mini-

mize generation of airborne dust.

It is recommended that full body clothing be worn to reduce the potential for skin irritation. Washable or dis-

posable clothing may be used. Do not take unwashed work clothing home. Work clothes should be washed

separately from other clothing. Rinse washing machine thoroughly after use. If clothing is to be laundered by

someone else, inform launderer of proper procedure. Work clothes and street clothes should be kept separate to

prevent contamination.

Product which has been in service at elevated temperatures (greater than 1800ºF/982ºC) may undergo partial

conversion to cristobalite, a form of crystalline silica. This reaction occurs at the furnace lining hot face. As a

consequence, this material becomes more friable; special caution must be taken to minimize generation of air-

borne dust. The amount of cristobalite present will depend on the temperature and length in service.

IARC has recently reviewed the animal, human, and other relevant experimental data on silica in order to criti-

cally evaluate and classify the cancer causing potential. Based on its review, IARC classified crystalline silica

as a group 2A carcinogen (probable human carcinogen).

The OSHA permissible exposure limit (PEL for cristobalite is 0.05 mg/m3 (respirable dust). The ACGIH

threshold limit value (TLV) for cristobalite is 0.05 mg/m3 (respirable dust) (ACGIH 1991-92). Use NIOSH or

MSHA approved equipment when airborne exposure limits may be exceeded. The minimum respiratory pro-

tection recommended for given airborne fiber or cristobalite concentrations are:

CONCENTRATION

0-1 fiber/cc or 0-0.05 mg/m3 cristobalite Optional disposable dust respirator (e.g. 3M

(the OSHA PEL) 9970 or equivalent).

Up to 5 fibers/cc or up to 10 times the Half face, air-purifying respirator equipped

OSHA PEL for cristobalite with high efficiency particulate air (HEPA)

filter cartridges (e.g. 3M 6000 series with

2040 filter or equivalent).

Up to 25 fibers/cc or 50 times the OSHA Full face, air-purifying respirator with high

PEL for cristobalite (2.5 mg/m3) efficiency particulate air (HEPA) filter cart-

ridges (e.g. 3M 7800S with 7255 filters or

equivalent) or powered air-purifying respirator

(PARR) equipped with HEPA filter cartridges

(e.g. 3M W3265S with W3267 filters or

equivalent).

Greater than 25 fibers/cc or 50 times the Full face, positive pressure supplied air respira-

OSHA PEL for cristobalite (2.5 mg/m3) tor (e.g. 3M 7800S with W9435 hose & W3196

low pressure regulator kit connected to clean

air supply or equivalent).

If airborne fiber or cristobalite concentrations are not known, as minimum protection, use NIOSH/MSHA approved

half face, air-purifying respirator with HEPA filter cartridges.

Insulation surface should be lightly sprayed with water before removal to suppress airborne dust. As water evapo-

rates during removal, additional water should be sprayed on surfaces as needed. Only enough water should be

sprayed to suppress dust so that water does not run onto the floor of the work area. To aid the wetting process, a sur-

factant can be used.

After RCF removal is completed, dust-suppressing cleaning methods, such as wet sweeping or vacuuming, should

be used to clean the work area. If dry vacuuming is used, the vacuum must be equipped with HEPA filter. Air

blowing or dry sweeping should not be used. Dust-suppressing components can be used to clean up light dust.

Product packaging may contain product residue. Do not reuse except to reship or return Ceramic Fiber products to

the factory.

1235 Jefferson Davis Highway

Arlington, Virginia 22202

Used by Permission

1. Never drop cylinders or permit them to strike each other violently.

2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weather and, to prevent

rusting, from the dampness of the ground. Cylinders should be stored in the shade when located in areas where extreme

temperatures are prevalent.

3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench, or placed in a

cylinder stand, and is ready to be used.

4. Avoid dragging, rolling, or sliding cylinders, even for short distance; they should be moved by using a suitable hand-

truck.

5. Never tamper with safety devices in valves or cylinders.

6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is attached to a pres-

surized system.

7. No part of cylinder should be subjected to a temperature higher than 52°C (125°F). A flame should never be permitted to

come in contact with any part of a compressed gas cylinder.

8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding, precautions must

be taken to prevent striking an arc against the cylinder.

1-2 SYSTEM OVERVIEW

a. Scope

This Instruction Bulletin provides the infor-

mation needed to install, start up, operate,

and maintain the Hazardous Area Oxymitter

4000. Signal conditioning electronics out-

puts a 4-20 mA signal representing an O2

value and provides a membrane keypad or

full function Local Operator Interface (LOI)

for setup, calibration, and diagnostics. This

same information, plus additional details,

can be accessed with the

HART Model 275/375 handheld communi-

cator or Asset Management Solutions

(AMS) software.

b. System Description

The Hazardous Area Oxymitter 4000 is

designed to measure the net concentration

of oxygen in an industrial process; i.e., the

oxygen remaining after all fuels have been

oxidized. The probe is permanently posi-

tioned within an exhaust duct or stack and

performs its task without the use of a

sampling system.

The equipment measures oxygen percent-

age by reading the voltage developed

across a heated electrochemical cell, which

consists of a small yttria-stabilized, zirconia

disc. Both sides of the disc are coated with

porous metal electrodes. When operated at

the proper temperature, the millivolt output

voltage of the cell is given by the following

Nernst equation:

EMF = KT log10(P1/P2) + C

Where:

1. P2 is the partial pressure of the oxy-

gen in the measured gas on one side

of the cell.

2. P1 is the partial pressure of the oxy-

gen in the reference air on the oppo-

site side of the cell.

3. T is the absolute temperature.

4. C is the cell constant.

5. K is an arithmetic constant.

NOTE

For best results, use clean, dry, instru-

ment air (20.95% oxygen) as the refer-

ence air.

Rosemount Analytical Inc. A Division of Emerson Process Management Description and Specifications 1-3

Hazardous Area Oxymitter 4000

When the cell is at operating temperature

and there are unequal oxygen concentra-

tions across the cell, oxygen ions will travel

from the high oxygen partial pressure side

to the low oxygen partial pressure side of

the cell. The resulting logarithmic output

voltage is approximately 50 mV per decade.

The output is proportional to the inverse

logarithm of the oxygen concentration.

Therefore, the output signal increases as

the oxygen concentration of the sample gas

decreases. This characteristic enables the

Hazardous Area Oxymitter 4000 to provide

exceptional sensitivity at low oxygen

concentrations.

The Hazardous Area Oxymitter 4000 meas-

ures net oxygen concentration in the pres-

ence of all the products of combustion,

including water vapor. Therefore, it may be

considered an analysis on a “wet” basis. In

comparison with older methods, such as the

portable apparatus, which provides an

analysis on a “dry” gas basis, the “wet”

analysis will, in general, indicate a lower

percentage of oxygen. The difference will

be proportional to the water content of the

sampled gas stream.

c. System Configuration

Hazardous Area Oxymitter 4000 units are

available in three length options, giving the

user the flexibility to use an in situ penetra-

tion appropriate to the size of the stack or

duct. The options on length are 457 mm

(18 in.), 0.91 m (3 ft), and 1.83 m (6 ft).

The electronics control probe temperatures

and provide an isolated output, 4-20 mA,

that is proportional to the measured oxygen

concentration. The power supply can accept

voltages of 90-250 VAC and 48/62 Hz; no

setup procedures are required. The oxygen

sensing cell is maintained at a constant

temperature by modulating the duty cycle of

the probe heater portion of the electronics.

The electronics accepts millivolt signals

generated by the sensing cell and produces

the outputs to be used by remotely con-

nected devices. The output is an isolated

4-20 mA linearized current.

Autocalibration System Options

The Oxymitter 4000 transmitter is available

with an integral or remote electronics pack-

age. Two calibration gas sequencers are

available to the Hazardous Area Oxymitter

4000, but they must be installed in a non-

hazardous, explosive-free environment: the

IMPS 4000 and the SPS 4000 (Figure 1-2).

Systems with multiprobe applications may

employ an optional IMPS 4000 Intelligent

Multiprobe Test Gas Sequencer. The IMPS

4000 provides automatic calibration gas

sequencing for up to four Hazardous Area

Oxymitter 4000 units and accommodates

autocalibrations based on the CALIBRA-

TION RECOMMENDED signal from the

Hazardous Area Oxymitter 4000, a timed

interval set up in HART or the IMPS 4000,

or whenever a calibration request is

initiated.

Hazardous Area Oxymitter 4000

For systems with one or two Hazardous

Area Oxymitter 4000 units per combustion

process, an optional remote mounted SPS

4000 Single Probe Autocalibration

Sequencer can be used with each Hazard-

ous Area Oxymitter 4000 to provide auto-

matic calibration gas sequencing. The

sequencer performs autocalibrations based

on the CALIBRATION RECOMMENDED

signal from the Hazardous Area Oxymitter

4000, a timed interval set up in HART, or

whenever a calibration request is initiated.

d. System Features

1. The CALIBRATION RECOMMENDED

feature detects when the sensing cell

is likely out of limits. This may eliminate

the need to calibrate on a “time since

last cal” basis.

2. The cell output voltage and sensitivity

increase as the oxygen concentration

decreases.

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the in-

trinsically safe version of the handheld

communicator.

3. Membrane keypad Figure 1-3 and

HART communication are standard.

To use the HART capability, you must

have either:

(a) HART Model 275/375 Communi-

cator.

(b) Asset Management Solutions

(AMS) software for the PC.

9. An operator can calibrate and com-

municate with the Hazardous Area

Oxymitter 4000 in one of three ways:

Accessing the probe keypad requires

opening the electronics housing.

Opening the electronic housing will

cause the loss of ALL hazardous per-

mits. Opening the electronics housing

in hazardous areas may cause an ex-

plosion resulting in loss of property,

severe personal injury, or death. It

may be required to get a hot work

permit from your company safety offi-

cer before opening the electronic

housing.

(a) Membrane Keypad. The mem-

brane keypad, housed within the

right side of the electronics hous-

ing, provides fault indication by

way of flashing LEDs. Calibration

can be performed from the mem-

brane keypad.

(b) LOI. The optional LOI takes the

place of the membrane keypad

and allows local communication

with the electronics. Refer to Sec-

tion 4 for more information.

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the in-

trinsically safe version of the handheld

communicator.

(c) Optional HART Interface. The

Hazardous Area Oxymitter 4000’s

4-20 mA output line transmits an

analog signal proportional to the

oxygen level. The HART output is

superimposed on the 4-20 mA out-

put signal. This information can be

accessed through the following:

e. Handling the Hazardous Area

Oxymitter 4000

It is important that printed circuit

boards and integrated circuits are

handled only when adequate antistatic

precautions have been taken to pre-

vent possible equipment damage.

The Hazardous Area Oxymitter 4000 is

designed for industrial applications.

Treat each component of the system

with care to avoid physical damage.

Some probe components are made

from ceramics, which are susceptible

to shock when mishandled.

f. System Considerations

Prior to installing your Hazardous Area

Oxymitter 4000, make sure you have all the

components necessary to make the system

installation. Ensure all the components are

properly integrated to make the system

functional.

After verifying that you have all the compo-

nents, select mounting locations and deter-

mine how each component will be placed

in terms of available line voltage, ambient

temperatures, environmental considera-

tions, convenience, and serviceability.

Figure 1-5 shows a typical system wiring.

A typical system installation with integral

electronics is illustrated in Figure 1-6. A

typical system installation with remote elec-

tronics is illustrated in Figure 1-7.

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the in-

trinsically safe version of the handheld

communicator.

Hazardous Area Oxymitter 4000

A source of instrument air is optional at

the Hazardous Area Oxymitter 4000 for

reference air use. Since the unit can be

equipped with an in-place calibration fea-

ture, provisions can be made to perma-

nently connect calibration gas bottles to the

Hazardous Area Oxymitter 4000.

If the calibration gas bottles will be perma-

nently connected, a check valve is required

next to the calibration fittings on the integral

electronics.

This check valve is to prevent breathing of

the calibration gas line and subsequent flue

gas condensation and corrosion.

The check valve is in addition to the stop

valve in the calibration gas kit and solenoid

valves in the IMPS 4000 or SPS 4000.

NOTE

The integral electronics is rated NEMA

4X (IP66) and is capable of operation

at temperatures up to 85°C (185°F).

The optional LOI is also rated for

operation at temperatures up to 85°C

(185°F). The infrared keypad function-

ality will degrade at temperatures

above 70°C (158°F).

Retain the original packaging for the

Hazardous Area Oxymitter 4000, in

case the components are to be

shipped to another site. This packag-

ing is designed to protect the product.

1-3 IMPS 4000 (OPTIONAL)

a. Flame Arrestor Ceramic Diffusion

Assembly

The flame arrestor ceramic diffusion as-

sembly, Figure 1-9, includes a set of baffles

between the cell and the stack gases. This

keeps 816°C (1500°F) cell temperatures

from igniting unburned fuel in the stack. The

ceramic diffusion assembly is also available

with a dust seal for use with the abrasive

shield assembly.

b. Flame Arrestor Snubber Diffusion

Assembly

The flame arrestor snubber diffusion as-

sembly, Figure 1-10, is satisfactory for most

applications. This element is also available

with a dust seal for use with an abrasive

shield.

c. Abrasive Shield Assembly

The abrasive shield assembly, Figure 1-11,

is a stainless-steel tube that surrounds the

probe assembly. The shield protects against

particle abrasion and condensations,

provides a guide for ease of insertion, and

acts as a position support, especially for

longer probes. The abrasive shield

assembly uses a modified diffusor and vee

deflector assembly, fitted with dual dust seal

packing.

Hazardous Area Oxymitter 4000

SECTION 2

INSTALLATION

The Hazardous Area Oxymitter 4000

and probe abrasive shield are heavy.

Use proper lifting and carrying proce-

dures to avoid personal injury.

Install all protective equipment covers

and safety ground leads after installa-

tion. Failure to install covers and

ground leads could result in serious

injury or death.

2-1 MECHANICAL INSTALLATION

a. Selecting Location

1. The location of the Hazardous Area

Oxymitter 4000 in the stack or flue is

most important for maximum accuracy

in the oxygen analyzing process. The

Hazardous Area Oxymitter 4000 must

be positioned so the gas it measures

is representative of the process. Best

results are normally obtained if the

Hazardous Area Oxymitter 4000 is

positioned near the center of the duct

(40 to 60% insertion). Longer ducts

may require several Hazardous Area

Oxymitter 4000 units since the O2 can

vary due to stratification. A point too

near the wall of the duct, or the inside

radius of a bend, may not provide a

representative sample because of the

very low flow conditions. The sensing

point should be selected so the proc-

ess gas temperature falls within a

range of 0° to 704°C (32° to 1300°F).

Figure 2-1 through Figure 2-5 provide

mechanical installation references.

The ambient temperature of the elec-

tronics housing must not exceed 70°C

(150°F). For higher ambient tempera-

tures, we recommend the remote

mounted electronics option.

NOTE

At temperatures up to 85°C (185°F)

inside the housing, the infrared keypad

will cease to function, but the transmit-

ter will continue to operate properly.

2. Check the flue or stack for holes and

air leakage. The presence of this con-

dition will substantially affect the accu-

racy of the oxygen reading. Therefore,

either make the necessary repairs or

install the Hazardous Area Oxymitter

4000 upstream of any leakage.

3. Ensure the area is clear of internal and

external obstructions that will interfere

with probe installation and access to

the membrane keypad or LOI. Allow

adequate clearance for removal of the

Hazardous Area Oxymitter 4000

(Figure 2-1 or Figure 2-3).

Do not allow the temperature of the

Hazardous Area Oxymitter 4000 elec-

tronics to exceed 85°C (185°F) or dam-

age to the unit may result.

b. Probe Installation

1. Ensure all components are available to

install the Hazardous Area Oxymitter

4000. If equipped with a ceramic dif-

fuser, make sure the diffuser is not

damaged.

2. The Hazardous Area Oxymitter 4000

probe may be installed intact, as it is

received.

NOTE

An abrasive shield is recommended

for high velocity particulates in the

flue stream (such as those in coal-

fired boilers, kilns, and recovery

boilers).

3. Weld or bolt mounting plate (Figure

2-5) onto the duct.

4. If using the optional ceramic diffusion

element, the vee deflector must be cor-

rectly oriented. Before inserting the

Hazardous Area Oxymitter 4000, check

the direction of flow of the gas in the

duct. Orient the vee deflector so the

apex points upstream toward the flow

(Figure 2-6). This may be done by

loosening the setscrews and rotating

the vee deflector to the desired posi-

tion. Retighten the setscrews.

5. In vertical installations, ensure the

system cable drops vertically from the

Hazardous Area Oxymitter 4000 and

the conduit is routed below the level of

the electronics housing. This drip loop

minimizes the possibility that moisture

will damage the electronics. See Figure

2-7.

6. If the system has an abrasive shield,

check the dust seal gaskets. The joints

in the two gaskets must be staggered

180 degrees. Make sure the gaskets

are in the hub grooves as the Hazard-

ous Area Oxymitter 4000 slides into the

15 degree forcing cone in the abrasive

shield.

NOTE

If process temperatures will exceed

200°C (392°F), use anti-seize com-

pound on the stud threads to ease

future removal of the Hazardous Area

Oxymitter 4000.

7. Insert probe through the opening in the

mounting plate and bolt the unit to the

plate.

NOTE

To maintain CE compliance, ensure a

good connection exists between the

mounting plate studs or earthing

screws on electronics housing and

earth.

8. Ensure the Hazardous Area Oxymitter

4000 is properly earthed by way of

both internal and external points.

Uninsulated stacks or ducts may

cause ambient temperatures around

the electronics to exceed 85°C (185°F),

which may cause overheating damage

to the electronics.

9. If duct work insulation is removed for

Hazardous Area Oxymitter 4000 probe

mounting, make sure the insulation is

replaced afterward. See Figure 2-7.

NOTE

For probe temperatures that will exceed

85°C (185°F), we recommend the remote

mounted electronics option.

10. Ensure the probe installation does not

obscure the warnings on the housing

covers.

Hazardous Area Oxymitter 4000

To meet the Safety Requirements of

IEC 1010 (EC requirement), and ensure

safe operation of this equipment, con-

nection to the main electrical power

supply must be made through a circuit

breaker (min 10 A) which will discon-

nect all current-carrying conductors

during a fault situation. This circuit

breaker should also include a me-

chanically operated isolating switch. If

not, then another external means of

disconnecting the supply from the

equipment should be located close by.

Circuit breakers or switches must

comply with a recognized standard

such as IEC 947.

The probe and probe abrasive shield

are heavy. Use proper lifting and car-

rying procedures to avoid personnel

injury.

To maintain explosion-proof protec-

tion, all cable entry devices and

blanking elements for unused aper-

tures must be certified flameproof,

suitable for the conditions of use and

be properly installed.

a. Remove screw (18, Figure 9-3), cover lock

(19), and captive washer (20). Remove

cover (17) from terminal block (15).

b. Connect Line Voltage. Connect the line, or

L1, wire to the L1 terminal and the neutral,

or L2 wire, to the N terminal. See Figure

2-9. The Hazardous Area Oxymitter 4000

automatically will configure itself for 90-250

VAC line voltage and 50/60 Hz. To avoid a

shock hazard, the power terminal cover

must be installed.

c. Connect 4-20 mA Signal and Calibration

Handshake/Logic I/O Leads (Figure 2-9).

1. 4-20 mA Signal. The 4-20 mA signal

represents the O2 value and can also

operate the Model 751 Loop LCD Dis-

play or any other loop powered display.

Superimposed on the 4-20 mA signal is

HART information that is accessible

through a Model 275/375 Handheld

Communicator or AMS software.

If using an IMPS 4000 or an SPS 4000,

install it in a non-hazardous, explosive-

free environment.

2. Calibration Handshake/Logic I/O. The

output signal can be used to trigger an

alarm or to provide a calibration hand-

shake signal to an IMPS or SPS 4000.

If autocalibration is not utilized, a

common bi-directional logic contact is

provided for any of the equipment

alarms listed in Table 8-1. The assign-

ment of alarms that will actuate this

contact is modified by one of seven

additional configuration settings (mode

1 through mode 7) listed in Table 4-1.

The logic contact is self-powered,

+5 VDC, with a 340 ohm series resis-

tance. An interposing relay is required

if the logic contact will annunciate a

higher voltage device, such as a light

or horn. An interposing relay may also

be required for certain DCS input

cards. A Potter & Brumfield model

R10S-E1Y1-J1.0K 3.2 mA DC (or

equal) interposing relay will be

mounted where the contact wires

terminate in the control/relay room.

d. Install cover (17, Figure 9-3) and secure

with captive washer (20), cover lock (19),

and screw (18).

c. Verify Hazardous Area Oxymitter 4000

Configuration

Located on the microprocessor board, the

top board, are two switches that configure

outputs for the Hazardous Area Oxymitter

4000 (Figure 3-2). SW1 determines if the

4-20 mA signal is internally or externally

powered. SW2 determines:

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the intrin-

sically safe version of the handheld

communicator.

1. Hazardous Area Oxymitter 4000

status, HART or LOCAL.

2. Oxygen range, 0 to 10% O2 or 0 to

25% O2. (0 to 40% O2 is also configur-

able only through HART/AMS.)

3. The 4-20 mA signal, at fault or power

up, 3.5 mA or 21.6 mA.

Remove power from the Hazardous

Area Oxymitter 4000 before changing

defaults. If defaults are changed under

power, damage to the electronics

package may occur.

d. SW1

The two settings are internally or externally

powering the 4-20 mA signal. The factory

setting is for the 4-20 mA signal to be inter-

nally powered.

e. SW2

The factory sets this switch as follows:

1. Position 1 is HART/LOCAL. This switch

setting controls the configuration of the

Hazardous Area Oxymitter 4000. The

defaults cannot be changed via HART-

/AMS unless the switch is in the HART

position. Placing SW2, position 1 in the

LOCAL position forces the O2 range to

the setting of position 2. The position 1

switch must be placed in the LOCAL

position or changes in SW2, position 2

will have no effect.

2. Position 2 determines the O2 range.

This can be set to either 0 to 10% O2

or 0 to 25% O2. The factory setting is

0 to 10% O2.

Typically, the probe’s sensing cell, in

direct contact with the process gases,

is heated to approximately 736°C

(1357°F). The external temperature of

the probe body may exceed 450°C

(842°F). If operating conditions also

contain high oxygen levels and com-

bustible gases, the Hazardous Area

Oxymitter 4000 may self-ignite.

If necessary, the O2 range can be con-

figured from 0 to 40% O2. To select

values within this range, set SW2,

position 1 to HART and then enter the

range via HART/AMS. Do not change

SW2, position 1 to LOCAL unless you

want to operate in the range specified

by SW2, position 2.

3. Position 3 determines the output at

startup or at an alarm. The settings are

3.5 mA or 21.6 mA. The factory setting

is 3.5 mA. At startup, the current at the

analog output is 3.5 mA or 21.6 mA.

4. Position 4 can be used to set the

heater for 115 or 220 Vac operation.

This switch is functional only when the

software is set for manual voltage

selection (Auto Tune = No). Otherwise,

the internal electronics auto detect the

input line voltage and sets the heater

voltage accordingly (Auto Tune = Yes).

f. Once the cell is up to operating tempera-

ture, the O2 percentage can be read:

1. Access TP5 and TP6 next to the mem-

brane keypad. Attach a multimeter

across TP5 and TP6. The calibration

and process gases can now be moni-

tored. Pressing the INC or DEC once

will cause the output to switch from the

process gas to the calibration gas.

Pressing INC or DEC a second time

will increase or decrease the calibra-

tion gas parameter. If the keys have

been inactive for one minute, the

output reverts to the process gas.

When a calibration has been initiated,

the value at TP5 and TP6 is the %O2

seen by the cell. Oxygen levels, as

seen on the multimeter, are:

3-4 Configuration with Keypad Rosemount Analytical Inc. A Division of Emerson Process Management

Hazardous Area Oxymitter 4000

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the intrin-

sically safe version of the handheld

communicator.

3-2 LOGIC I/O

This two-terminal logic contact can be config-

ured either as a solid-state relay-activated alarm

or as a bi-directional calibration handshake sig-

nal to an IMPS 4000 or SPS 4000. The configu-

ration of this signal depends on the setting of

the LOGIC I/O PIN MODE via HART/AMS or

LOI. The ten different modes available are

explained in Table 3-1.

a. Alarm

When configured as an alarm, this signal

alerts you to an out-of-spec condition. The

output is +5 Vdc in series with a 340 ohm

resistor.

For optimum performance, Rosemount rec-

ommends connecting the output to a Potter

& Brumfield 3.2 mA DC relay (P/N R10S-

E1Y1-J1.0K).

Of the ten modes in Table 3-1, modes 0

through 7 are the alarm modes. The factory

default is mode 5 for Hazardous Area Oxy-

mitter 4000 units without an IMPS 4000 or

SPS 4000. In this mode, the output will sig-

nal when a unit alarm or a CALIBRATION

RECOMMENDED indication occurs.

b. Calibration Handshake Signal

If using an optional IMPS 4000 or SPS

4000, the logic I/O must be configured for

calibration handshaking. Of the ten modes

in Table 3-1, only modes 8 and 9 are con-

figured for calibration handshaking. For a

Hazardous Area Oxymitter 4000 with an

IMPS 4000 or an SPS 4000, the factory

sets the default to mode 8. In this mode,

the logic I/O will be used to communicate

between the Hazardous Area Oxymitter

4000 and the sequencer and to signal the

sequencer when a CALIBRATION REC-

OMMENDED indication occurs.

Hazardous Area Oxymitter 4000

3-3 RECOMMENDED CONFIGURATION

a. 4-20 mA Signal Upon Critical Alarm

Rosemount recommends that the factory

default be utilized. The 4-20 mA signal will

go to the 3.5 mA level upon any critical

alarm which will cause the O2 reading to be

unusable. Customer can also select 21.6

mA as the failure setting if normal opera-

tions cause O2 readings to go below the

zero % O2 (3.5 mA) level.

If the O2 measurement is being utilized as

part of an automatic control loop, the loop

should be placed into manual upon this

failure event or other appropriate action

should be taken.

b. Calibration

Rosemount recommends utilizing an auto-

calibration system, actuated by the “calibra-

tion recommended” diagnostic. New O2 cells

may operate for more than a year, but older

cells may require recalibration every few

weeks as they near the end of their life.

This strategy ensures that the O2 reading

is always accurate, and eliminates many

unnecessary calibrations based on calendar

days or weeks since previous calibration.

When utilizing the SPS 4000 or IMPS 4000,

consider wiring some or all associated

alarm contacts.

1. CALIBRATION INITIATE. Contact from

the control room to an SPS 4000 or

IMPS 4000 (one per probe) provides

the ability to manually initiate a calibra-

tion at any time from the control room.

Note that calibrations can also be

initiated from a HART handheld com-

municator, from Asset Management

Solutions software, or from the keypad

on the Hazardos Area Oxymitter 4000.

2. IN CALIBRATION. One contact per

probe provides notification to the con-

trol room that the “calibration recom-

mended” diagnostic has initiated an

automatic calibration through the SPS

4000 or IMPS 4000. If the O2 signal is

being utilized in an automatic control

loop, this contact should be utilized

to place the control loop into manual

during calibration.

3. CALIBRATION FAILED. One contact

per probe from an SPS 4000 or IMPS

4000 to the control room for notification

that the calibration procedure failed.

Grouped with this alarm is an output

from a pressure switch which indicates

when the calibration gas bottles are

empty.

4. 4-20 mA SIGNAL DURING

CALIBRATION. The 4-20 mA signal

can be configured to respond normally

during any calibration, or it can be con-

figured to hold the last O2 value upon

the initiation of calibration. The factory

default is for the 4-20 mA signal to

track (operate normally) throughout

calibration. Holding the last O2 value

may be useful if several probes are

being averaged for the purpose of

automatic control. Unless several

probes are being averaged, always

place control loops that are using the

O2 signal into the manual mode prior to

starting the calibration.

Configuration

Located on the microprocessor board are

two switches that configure Hazardous

Area Oxymitter 4000 outputs (Figure 4-2).

To access these switches, the LOI module

must be removed. SW1 determines if the

4-20 mA signal is internally or externally

powered. SW2 determines:

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the intrin-

sically safe version of the handheld

communicator.

1. Hazardous Area Oxymitter 4000

status, HART or LOCAL.

2. Oxygen range, 0 to 10% O2 or 0 to

25% O2. (0 to 40% O2 is also configur-

able only through HART/AMS.)

3. The 4-20 mA signal, at fault or power

up, 3.5 mA or 21.6 mA.

Remove power from the Hazardous

Area Oxymitter 4000 before changing

defaults. If defaults are changed under

power, damage to the electronics

package may occur.

d. SW1

The two settings are internally or externally

powering the 4-20 mA signal. The factory

setting is for the 4-20 mA signal to be inter-

nally powered.

e. SW2

The factory sets this switch as follows:

1. Position 1 is HART/LOCAL. This switch

setting controls the configuration of the

Hazardous Area Oxymitter 4000. The

defaults cannot be changed via

HART/AMS or the LOI unless the

switch is in the HART position. Placing

SW2, position 1 in the LOCAL position

forces the O2 range to the setting of

position 2. The position 1 switch must

be in the LOCAL position or changes in

SW2, position 2 will have no effect.

2. Position 2 determines the O2 range.

This can be set to either 0 to 10% O2

or 0 to 25% O2. The factory setting is

0 to 10% O2.

Typically, the probe’s sensing cell, in

direct contact with the process gases,

is heated to approximately 736°C

(1357°F). The external temperature of

the probe body may exceed 450°C

(842°F). If operating conditions also

contain high oxygen levels and com-

bustible gases, the Hazardous Area

Oxymitter 4000 may self-ignite.

If necessary, the O2 range can be con-

figured from 0 to 40% O2. To select

values within this range, set SW2,

position 1 to HART and then enter the

range via HART/AMS or the LOI. Do

not change SW2, position 1 to LOCAL

unless you want to operate in the

range specified by SW2, position 2.

3. Position 3 determines the output at

startup or at an alarm. The settings are

3.5 mA or 21.6 mA. The factory setting

is 3.5 mA. At startup, the current at the

analog output is 3.5 mA or 21.6 mA.

4. Position 4 can be used to set the

heater for 115 or 220 Vac operation.

This switch is functional only when the

software is set for manual voltage

selection (Auto Tune = No). Otherwise,

the internal electronics auto detect the

input line voltage and sets the heater

voltage accordingly (Auto Tune = Yes).

heater turns on. It takes approximately one

half hour for the cell to heat to operating

temperature. This condition is indicated by

the top four LEDs (DIAGNOSTIC ALARMS)

on the membrane keypad (Figure 5-1).

Starting with the CALIBRATION LED, the

LEDs light in ascending order until all four

LEDs are on. At this point, all four turn off

and the cycle starts again. This ramp cycle

continues until the cell is up to operating

temperature.

b. Operating Display

The ramp cycle turns into a cycle where the

diagnostic LEDs light in sequence from the

top to the bottom, one at a time. After the

bottom LED turns on, the sequence starts

again at the top with the HEATER T/C LED

(Figure 5-1).

c. Error

If there is an error condition at startup, one

of the diagnostics LEDs will be blinking.

Refer to Section 8 TROUBLESHOOTING,

to determine the cause of the error. Clear

the error, cycle power, and the operating

display should return.

6-3 NAVIGATING THE LOCAL OPERATOR

INTERFACE

a. Overview

The Local Operator Interface (LOI), shown

in Figure 6-3, utilizes a bright blue gas-

florescent display. Intensity is adjustable.

There is an Infra-red LED source and a

detector for each key. The detectors can

detect a finger placed above the button

through the glass window. There is no need

to open the instrument in bad weather or in

hazardous areas in order to access the

electronics.

It should be noted that the Hazardous Area

Oxymitter 4000 also utilizes HART commu-

nications, permitting access to all instrument

functionality anywhere the 4-20 mA signal

terminates via a HART model 275/375

handheld communicator.

b. Lockout

The Local Operator Interface (LOI) has

a lockout feature that prevents nuisance

actuation by someone brushing against the

glass window, raindrops, dirt, insects, etc.

This lockout mode is automatically estab-

lished when no buttons are pushed for 30

seconds (default). This countdown to lock-

out is configurable.

In order to unlock the display, input a "Z"

pattern. First, push the top left (gray) arrow,

then the top right, followed by the bottom

left and finally the bottom right. The "LK"

notation in the upper right corner of the

display will now disappear. Push the gray

arrow at the top left hand corner once more

to enter into the menu structure. Once one

moves deeper into the menu structure,

additional time is provided to the user so

that the lockout initiation does not become

a nuisance. This additional “revert” time is

defaulted at one hour and is also user con-

figurable.

6-4 LOI KEY DESIGNATIONS

The gray key (top left) key will move one level

higher in the menu structure. When entering

numbers, this key will move the cursor to the

left. This key also doubles as an “Enter” key,

once numbers are entered, and when the cursor

is moved to it’s left-most position. The new data

entry value will appear in the top line of the LOI

display once it’s accepted.

The blue key (bottom left) acts as a selector

when choosing from among a number of menu

items. This key also will move the cursor to the

right when entering numbers.

Up/Down keys (to the left side of the keypad)

are used to increment up and down when

selecting from a series of menu picks. They are

also used for incrementing values up and down

for data input.

3. O2 - Reset Values – Resets factory

default values.

4. O2 Output Tracks – 4 to 20 mA signal

can be held at the last value during

calibration, or the signal can be left to

track the cal gases.

5. O2 Cal Interval – If automatic calibra-

tion is selected, this selects the interval

between calibrations.

6. O2-Next Cal – If automatic calibration

is selected, this selects the time until

the first initial calibration takes place.

Rosemount Analytical Inc. A Division of Emerson Process Management Startup and Operation with LOI 6-5

Hazardous Area Oxymitter 4000

7. Gas Time – How long should each cal

gas flow. Factory default is 300 sec-

onds, but the user may want to vary

this depending upon the length of cali-

bration gas tubing runs.

8. Purge Time – Used if the O2 output is

selected to hold the last value during

calibration. After the second cal gas is

removed, how long until the sensor

comes back to the normal process

reading, and the 4-20 mA signal can

be released.

9. Auto Calib? – Select “Yes” if an SPS

or IMPS autocalibration system is part

of the system.

b. SYSTEM/Input/Output

1. Analog – Pertaining to the analog

4-20 mA signal representing O2.

(a) O2 Type – 4-20 mA signal may

be configured to increase with

increasing O2 or the reverse.

(b) O2 Range – Upper O2 range is

user selectable.

(c) O2 Alarm Level – User can config-

ure the digital output to alarm at a

given O2 level.

(d) Do O2 Trim – Procedure for cali-

brating the 4-20 mA signal to a

precision mA source. Procedure

is intuitive.

2. Digital – A bi-directional logic signal

may be configured as an alarm, or as

a calibration handshake signal.

(a) Logic I/O Mode – One of 9 different

sets of conditions can be set for

the digital signal. See Table 8-2.

(b) Low O2 Alarm – If any of the con-

ditions noted above include a low

O2 process alarm, set the value

here.

(c) Input State – Notes the current

condition of the bi-directional digital

signal.

(d) Force Output – Forces the output

state of the signal to either open or

closed. This is used primarily when

diagnosing potential problems with

this signal.

c. SYSTEM/Parameters

1. O2 Slope – O2 slope is data regarding

the strength of the sensing cell output.

This information is automatically cal-

culated after a calibration, and the user

does not normally input this data.

2. O2 Constant – O2 constant is the

amount of voltage a cell generates

with ambient air as the calibration gas.

Again, this is normally calculated as a

result of calibration, and is not normally

input by the user.

3. O2 T90 Time – Some users may feel

that the O2 reading is too active for

certain processes. This feature permits

the user to dampen the O2 signal. The

default value is zero seconds damp-

ening.

4. Auto Tune – The electronics detects

the line voltage powering the instru-

ment automatically, and picks proper

algorithms for heater control. User can

force a high voltage algorithm, or a low,

but Auto Tune is the default, and is

recommended.

5. Lockout Time – Keypad lockout time

default is 30 sec., but is user configur-

able. A “Z” keypad pattern will unlock

the keypad.

6. Revert Time – Once a user goes one

level deep into the menu structure, an

additional “revert time” is provided to

prevent nuisance lockouts. One hour is

the default, and it is user configurable.

7. Luminance – Gas florescence bright-

ness is user adjustable.

Hazardous Area Oxymitter 4000

SECTION 7

HART/AMS

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that this

is the case even when using the in-

trinsically safe version of the handheld

communicator.

7-1 OVERVIEW

The HART Communicator is a handheld com-

munications interface device. It provides a

common communications link to all microproc-

essor-based instruments that are HART com-

patible. The handheld communicator contains

an 8 x 21 character liquid crystal display (LCD)

and 25 keys. A pocket-sized manual, included

with the HART Communicator, details the spe-

cific functions of all the keys.

To interface with the Hazardous Area Oxymitter

4000, the HART Communicator requires a ter-

mination point along the 4-20 mA current loop

and a minimum load resistance of 250 ohms

between the communicator and the power

supply.

The HART Communicator accomplishes its task

using a frequency shift keying (FSK) technique.

With the use of FSK, high-frequency digital

communication signals are superimposed on

the Hazardous Area Oxymitter 4000’s 4-20 mA

current loop. The HART communicator does not

disturb the 4-20 mA signal, since no net energy

is added to the loop.

The HART Communicator may be interfaced

with a personal computer (PC), providing that

special software has been installed. To connect

the HART Communicator to a PC, an interface

adapter is required. Refer to the proper HART

Communicator documentation in regard to the

PC interface option.

7-2 HART COMMUNICATOR SIGNAL LINE

CONNECTIONS

The HART Communicator can connect to the

Hazardous Area Oxymitter 4000’s analog output

signal line at any wiring termination in the 4-20

mA current loop. There are two methods of

connecting the HART Communicator to the

signal line. For applications in which the signal

line has a load resistance of 250 ohms or more,

refer to method 1. For applications in which the

signal line load resistance is less than 250

ohms, refer to method 2.

a. Method 1, For Load Resistance ≥ 250

Ohms

Refer to Figure 7-1 and the following steps

to connect the HART Communicator to a

signal line 250 ohms or more of load

resistance.

Explosions can result in death or seri-

ous injury. Do not make connections

to the HART Communicator's serial

port, 4-20 mV signal line, or NiCad re-

charger jack in an explosive

atmosphere.

Using the supplied lead set, connect the

HART Communicator in parallel with to the

Hazardous Area Oxymitter 4000. Use any

wiring termination points in the analog out-

put 4-20 mA signal line.

b. Method 2, For Load Resistance < 250

Ohms

Refer to Figure 7-2 and the following steps

to connect the HART Communicator to a

signal line with less than 250 ohms load

resistance.

Explosions can result in death or seri-

ous injury. Do not make connections

to the HART Communicator's serial

port, 4-20 mA signal line, or NiCad re-

charger jack in an explosive

atmosphere.

1. At a convenient point, break the analog

output 4-20 mA signal line and install

the optional 250 ohm load resistor.

2. Plug the load resistor into the loop

connectors (located on the rear panel

of the HART Communicator).

designated AMS software into the PC. Then link

the HART Communicator to the PC using the

interface PC adapter that connects to the serial

port (on the communicator rear panel).

Refer to the proper HART Communicator docu-

mentation in regard to the PC interface option.

7-4 OFF-LINE AND ON-LINE OPERATIONS

The HART Communicator can be operated both

off-line and on-line.

a. Off-line operations are those in which the

communicator is not connected to the Haz-

ardous Area Oxymitter 4000. Off-line op-

erations can include interfacing the HART

Communicator with a PC (refer to applica-

ble HART documentation regarding

HART/PC applications.

b. In the on-line mode, the communicator is

connected to the 4-20 mA analog output

signal line. The communicator is connected

in parallel to the Hazardous Area Oxymitter

4000 or in parallel to the 250 ohm load

resistor.

NOTE

If the HART Communicator is turned

on while connected to the 4-20 mA

SECTION 8

TROUBLESHOOTING

8-1 OVERVIEW

While the Hazardous Area Oxymitter 4000

electronics provides a significant number of

diagnostic alarms to assist in troubleshooting

potential problems, it’s good to place these

alarms in perspective with respect to the

instrument’s operating principles:

a. When the Zirconium Oxide sensing cell is

heated to its setpoint [736°C (1357°F)], the

cell will generate a voltage that represents

the difference between the process O2%

and the reference O2% inside the probe

(20.95% O2 ambient air).

b. Test points, Figure 8-1, are provided to read

the raw millivolt value generated by the

ther-mocouple that controls both the cell

temperature and the raw cell signal.

c. The cell temperature at test points 3 and 4

should always be stable at approximately

29 to 30 millivolts, which represents the

736°C setpoint temperature.

d. When flowing calibration gasses, the raw

cell millivolt value at test points 1 and 2

should represent the levels on the chart in

Figure 8-1. Note that the raw cell millivolt

value increases logarithmically as the O2

concentration decreases.

Install all protective equipment covers

and safety ground leads after trouble-

shooting. Failure to install covers and

ground leads could result in serious

injury or death.

8-2 GENERAL

The troubleshooting section describes how to

identify and isolate faults that may develop in

the Hazardous Area Oxymitter 4000. When

troubleshooting, reference the following.

a. Grounding

It is essential that adequate grounding pre-

cautions are taken when installing the sys-

tem. Thoroughly check both the probe and

electronics to ensure the grounding quality

has not degraded during fault finding. The

system provides facilities for 100% effective

grounding and the total elimination of

ground loops.

b. Electrical Noise

The Hazardous Area Oxymitter 4000 has

been designed to operate in the type of

environment normally found in a boiler room

or control room. Noise suppression circuits

are employed on all field terminations and

main inputs. When fault finding, evaluate

the electrical noise being generated in the

immediate circuitry of a faulty system.

Ensure all cable shields are connected to

earth.

c. Loose Integrated Circuits

The Hazardous Area Oxymitter 4000 uses a

microprocessor and supporting integrated

circuits (IC). If the electronics are handled

roughly during installation or located where

subjected to severe vibration, the ICs could

work loose. Before troubleshooting the

system, ensure all ICs are fully seated.

d. Electrostatic Discharge

Electrostatic discharge can damage the ICs

used in the electronics. Before removing or

handling the processor board or the ICs,

ensure you are at ground potential.

8-3 ALARM INDICATIONS

The majority of the fault conditions for the

Hazardous Area Oxymitter 4000 will be indi-

cated by one of the four LEDs referred to as

diagnostic, or unit alarms on the operator’s key-

pad (Figure 8-2). An LED will flash a code that

will correspond to an error message. Only one

LED will blink at a time. An alarm code guide

is provided inside the screw-on cover for the

electronics.

Alarm indications will be also available via the

optional LOI or the HART Model 275/375 hand-

held communicator and Rosemount’s Asset

Management software. When the error is cor-

rected and/or power is cycled, the diagnostic

alarms will clear or the next error on the priority

list will appear.

8-4 ALARM CONTACTS

a. If autocalibration is not utilized, a common

bi-directional logic contact is provided for

any of the diagnostic alarms listed in Table

8-1. The assignment of alarms which can

actuate this contact can be modified to one

of seven additional groupings (mode 0

through mode 7) listed in Table 7-1.

The logic contact is self-powered, +5 VDC,

with a 340 ohm series resistance. An inter-

posing relay will be required if this contact is

to be utilized to annunciate a higher voltage

device, such as a light or horn. An inter-

posing relay may also be required for cer-

tain DCS input cards.

A Potter & Brumfield R10S-E1Y1-J1.0K 3.2

mA DC or an equal interposing relay will be

mounted where the contact wires terminate

in the control/relay room.

b. If autocalibration systems are utilized, the

bi-directional logic contact is utilized as a

“hand-shake” signal between the autocali-

bration system (SPS 4000 or IMPS 4000)

and is unavailable for alarming purposes.

The following additional contacts are pro-

vided through the autocalibration systems:

1. SPS 4000 and IMPS 4000, 1-4 probes.

(a) One contact closure per probe

from the control room to the SPS

4000 or IMPS 4000 for “calibration

initiate”.

(b) One contact output per probe from

the SPS 4000 or IMPS 4000 to the

control room for “in calibration”

notification.

(c) One contact output per probe from

the SPS 4000 or IMPS 4000 to the

control room for “calibration failed”

notification. (Includes output from

pressure switch indicating “cal gas

bottles empty”).

2. Additional IMPS 4000 Alarm Contacts.

(a) One contact per IMPS 4000 for

“low calibration gas flowing”.

(b) One contact per IMPS 4000 for

“high calibration gas flowing”.

NOTE

The 4-20 mA signal can be configured

to respond normally during any cali-

bration, or can be configured to hold

the last O2 value upon the initiation of

calibration. Factory default is for the

4-20 mA signal to operate normally

throughout calibration.

NOTE

Holding the last O2 value may be useful

if several probes are being averaged

for the purpose of automatic control.

Unless several probes are being aver-

aged, always place any control loops

using the O2 signal into manual prior to

calibrating.

8-5 IDENTIFYING AND CORRECTING ALARM

INDICATIONS

For a Hazardous Area Oxymitter 4000 with a

membrane keypad, faults are indicated by four

diagnostic, or unit, alarm LEDs. A pattern of

repeating blinks define the problem. A con-

densed table of the errors and the correspond-

ing blink codes can be found on the inside right

cover of the electronics housing. Table 8-1 also

identifies the blink code and fault status of each

LED as well as the output of the 4-20 mA signal

line and a fault number that corresponds to the

troubleshooting instructions provided in this

section.

For a Hazardous Area Oxymitter 4000 with the

optional LOI, alarm messages are displayed on

the LOI display window when the alarm status

display is accessed via the LOI menu. A listing

of the alarm/fault messages and the related fault

status descriptions and fault numbers are

shown in Table 8-2.

8-6 HAZARDOUS AREA OXYMITTER 4000

PASSES CALIBRATION, BUT STILL

READS INCORRECTLY

There are a few fault conditions where no alarm

indication is present and the probe passes cali-

bration, but the O2 reading may still be incorrect:

a. Probe passes calibration, but still ap-

pears to read high.

1. There may be a leak that is permitting

ambient air to mix with the process

gases. Since many combustion proc-

esses are slightly negative in pressure,

ambient air can be sucked into the cell

area, biasing the O2 reading upward.

(a) Make sure that the calibration gas

line is capped tightly between cali-

brations. If autocal is used, make

sure the check valve is seating

properly.

(b) If an abrasive shield is installed

to protect the entire probe from

particulate erosion, a leak in the

probe flange gasket can allow

ambient air to migrate down the

annular space between the probe

and shield, and then into the cell.

Always install a new probe flange

gasket when re-installing a probe.

2. There may be a leak inside the probe

itself, permitting the reference air

(20.95% O2) to mix with the process

gases at the cell. To confirm this leak

condition, instrument air will need to be

connected for reference. Pressurize

the inside (reference side) of the probe

by plugging the reference air exhaust

port with your finger for 1 minute. The

O2 reading should decrease slightly. If

the O2 reading increases during this

test, there is a leak inside the probe.

(a) Acid condensation inside the probe

can degrade the red silicon tube

(item 38, Figure 9-3) that carries the

cal gas to the cell. Remove the

housing (11) to inspect this hose.

(See Section 9, MAINTENANCE

AND SERVICE).

(b) The sensing cell is bolted to the

end of the probe, and uses a cor-

rugated metallicseal (item 25,

Figure 9-3) to separate the process

gases from the ambient reference

air. This seal can be used only one

time, so always replace this seal

when a cell is replaced. Always

apply anti-seize compound on both

sides of the corrugations.

b. Probe passes calibration, but still

appears to read low.

The diffusion element at the end of the

probe is a passive filter. It plugs very slowly,

since there is no active flow being drawn

across it. In applications that have a heavy

particulate loading (coal or wood fired boil-

ers, cement and lime kilns, catalyst regen-

eration, recovery boilers, etc.), this diffusion

element will eventually plug.

It is important not to pressurize the sensing

cell during calibrations by flowing excessive

cal gas against a plugged diffuser. Calibra-

tion flow rates should be set only when a

new diffuser is installed. As the diffuser

plugs, do not adjust the flow rates upward.

How do I detect a plugged diffuser?

1. The O2 signal's speed of response will

degrade. The O2 trend in the control

room will become smoother.

2. When calibrating, the calibration gas

flow rate will be noted to be lower.

Never readjust this flow upwards.

Adjust this flow only when a new

diffuser is installed.

3. Always note the time it takes for the

cell to recover to the normal process

value after the cal gas is removed. As

the diffuser plugs, this recovery time

will get longer and longer. Use the

Calibration Record form provided in

this manual.

Can I calibrate a badly plugged diffuser?

1. It may not be possible to immediately

replace a plugged diffuser while the

process is on line.

2. One can calibrate the probe without

pressurizing the cell by adjusting the

calibration gas flow rate downward

before calibration. For instance, say

the process is at 3%, and the first

calibration gas is 8%. Adjust the flow

of cal gas downward until the reading

begins to migrate from 8% to lower

values, indicating that process gases

are now mixing in with the calibration

gases.

3. Adjust the flow rate back up until this

mixing is just eliminated. Calibrate at

this flow rate. Replace the diffuser at

the first opportunity.

SECTION 9

MAINTENANCE AND SERVICE

9-1 OVERVIEW

This section identifies the calibration methods

available and provides the procedures to main-

tain and service the Hazardous Area Oxymitter

4000.

When working on this equipment on

the laboratory bench, be aware that

the Hazardous Area Oxymitter 4000,

probe tube, and flame arrestor hub

can be hot [up to 300°C (572°F)] in the

region of the probe heater.

Install all protective equipment covers

and safety ground leads after equip-

ment repair or service. Failure to in-

stall covers and ground leads could

result in serious injury or death.

9-2 CALIBRATION – HAZARDOUS AREA

OXYMITTER 4000 WITH KEYPAD

a. During a calibration, two calibration gases

with known O2 concentrations are applied

to the Hazardous Area Oxymitter 4000.

Slope and constant values calculated from

the two calibration gases determine if the

Hazardous Area Oxymitter 4000 is correctly

measuring the net concentration of O2 in

the industrial process. A calibration record

sheet is provided on the previous page. Use

photocopies of the calibration record sheet

to track transmitter performance.

Before calibrating the Hazardous Area

Oxymitter 4000, verify that the calibration

gas parameters are correct by setting the

gas concentrations (See paragraph 5-2a.5

or 6-5.) used when calibrating the unit and

by setting the calibration gas flowmeter.

The calibration gas flowmeter regulates the

calibration gas flow and must be set to 5

scfh. However, only adjust the flowmeter to

5 scfh after placing a new diffuser on the

end of the probe. Adjusting the flowmeter at

any other time can pressurize the cell and

bias the calibration.

In applications with a heavy dust loading,

the O2 probe diffusion element may become

plugged over time, causing a slower speed

of response. The best way to detect a

plugged diffusion element is to note the time

it takes the Hazardous Area Oxymitter 4000

to return to the normal process reading after

the last calibration gas is removed and the

calibration gas line is blocked off. A plugged

diffusion element also can be indicated by a

slightly lower reading on the flowmeter.

Change the diffusion element when the

calibration gas flowmeter reads slightly

lower during calibration or when response

to the process flue gases becomes very

slow. Each time the diffusion element is

changed, reset the calibration gas flowme-

ter to 5 scfh and calibrate the Hazardous

Area Oxymitter 4000. To change the diffu-

sion element, refer to paragraph 9-4i.

b. Three types of calibration methods are

available: automatic, semi-automatic, and

manual.

NOTE

A calibration can be aborted any time

during the process. Press the CAL key

(Figure 9-1) on the Hazardous Area

Oxymitter 4000 keypad three times

within three seconds, or abort via the

LOI, HART/AMS, or an IMPS 4000. An

aborted calibration will retain the values

of the previous good calibration.

9-2 Maintenance and Service Rosemount Analytical Inc. A Division of Emerson Process Management

Hazardous Area Oxymitter 4000

The HART option is not protected by

energy limiting barriers. It must not be

interfaced from within the hazardous

area. The 4-20 mA cables should be

routed and the connections made out-

side the hazardous area. Note that

this is the case even when using the

intrinsically safe version of the hand-

held communicator.

Do not install an IMPS 4000 or SPS

4000 within the hazardous area.

Installing the unit in a potentially

explosive environment could cause

serious injury or death and equipment

damage. Ensure the sequencer is

installed in a safe area.

1. Automatic Calibration. Automatic

calibrations require no operator action.

However, the calibration gases must

be permanently piped to the Hazard-

ous Area Oxymitter 4000, an SPS

4000 or IMPS 4000 must be installed

to sequence the gases, and the logic

I/O must be set to mode 8 via

HART/AMS so the sequencer and

Hazardous Area Oxymitter 4000 can

communicate.

Depending on your system setup, an

automatic calibration can be initiated

by the following methods:

(a) The Hazardous Area Oxymitter

4000’s CALIBRATION RECOM-

MENDED alarm signals that a

calibration is required.

(b) Use the HART/AMS or the LOI to

enter a “time since last cal” (CAL

INTRVL) parameter that will initiate

an automatic calibration at a

scheduled time interval (in hours).

To configure the CAL INTRVL

parameter, refer to paragraph 7-8

for the HART/AMS, or paragraph

6-5 for the LOI.

described, the Hazardous Area Oxy-

mitter 4000’s CALIBRATION REC-

OMMENDED alarm signals an IMPS

4000 or SPS 4000 to initiate a calibra-

tion. The sequencer sends an “in cal”

2. Semi-Automatic Calibration. Semi-

automatic calibrations only require

operator initiation. However, the cali-

bration gases must be permanently

piped to the Hazardous Area Oxymitter

4000, an SPS 4000 or IMPS 4000

must be installed to sequence the

gases, and the logic I/O must be set

to mode 8 or 9 via HART/AMS to allow

the sequencer and the Hazardous Area

Oxymitter 4000 to communicate.

Depending on your system setup,

a semi-automatic calibration can be

initiated by the following methods:

(a) Hazardous Area Oxymitter 4000

with membrane keypad. Press the

CAL key on the Hazardous Area

Oxymitter 4000 keypad.

(b) Hazardous Area Oxymitter 4000

with LOI. Select “Start Calib” from

the CALIBRATION menu.

(c) IMPS 4000. Use the IMPS 4000

keypad to change the InitCalX

parameter of the CHANGE PRE-

SETS display mode from 0000 to

0001. Refer to the IMPS 4000

Intelligent Multiprobe Test Gas

Sequencer Instruction Bulletin for

more information.

(d) HART. Use the HART Communi-

cator to access the O2 CALIBRATE

menu and perform the O2 CAL

method. Refer to paragraph 7-7 for

the complete calibration procedure.

(e) AMS. Refer to AMS documentation

for more information.

(f) Remote Contact. Initiate a calibra-

tion from a remote location via the

remote contact input connection

provided by an IMPS 4000 or SPS

4000. Refer to the documentation

available for the control system in

use for more information.

Once a semi-automatic calibration is

initiated by any of the methods previ-

ously described, the Hazardous Area

Oxymitter 4000’s CALIBRATION

RECOMMENDED alarm signals an

IMPS 4000 or SPS 4000 to initiate a

calibration. The sequencer sends an

“in cal” signal to the control room so

that any automatic control loops can be

placed in manual. Then, the sequencer

begins to sequence the calibration

gases.

3. Manual Calibration with Membrane

Keypad. Manual calibrations must be

performed at the Hazardous Area

Oxymitter 4000 site and will require

operator intervention throughout the

process. Manual calibration instruc-

tions, in condensed form, can also be

found on the inside of the right elec-

tronics housing cover. See Figure 9-2.

Use the following procedure to perform

a manual calibration:

(a) Place control loop in manual.

(b) Verify the calibration gas parame-

ters are correct per paragraph

9-2a.

(c) If performing a manual calibration

with the CALIBRATION RECOM-

MENDED LED off and the CAL

LED off, start at step 1.

(d) If performing a manual calibration

with the CALIBRATION RECOM-

MENDED LED on and the CAL

LED on, start at step 2.

1 Push the CAL key. The CALI-

BRATION RECOMMENDED

LED will come on and the

CAL LED will be on solid. If a

multimeter is attached across

TP5 and TP6, the reading will

display the percentage of

oxygen seen by the cell.

LED will flash continuously.

The Hazardous Area Oxymit-

ter 4000 can be configured

so that the 4-20 mA signal

will hold the last value. The

default condition is for the

output to track. A flashing LED

indicates that the Hazardous

Area Oxymitter 4000 is ready

to accept the first calibration

gas.

3 Apply the first calibration gas.

(Electronics will abort the cali-

bration if step 4 is not done

within 30 minutes).

4 Push the CAL key; the CAL

LED will be on solid. A timer is

activated to allow the calibra-

tion gas adequate time to flow

(default time of five minutes).

When the timer times out, the

Hazardous Area Oxymitter

4000 has taken the readings

using the first calibration gas

and the CAL LED will flash

continuously. The flashing

indicates the Hazardous Area

Oxymitter 4000 is ready to

take readings using the sec-

ond calibration gas.

5 Remove the first calibration

gas and apply the second

calibration gas. (Electronics

will abort the calibration if

step 6 is not done within 30

minutes).

6 Push the CAL key; the CAL

LED will be on solid. The timer

calibration). If the slope or the

constant is out of specifica-

tion, a diagnostic alarm LED

will be flashing. The diagnos-

tic alarm will remain active

until the purge cycle is over. If

the three pattern flash occurs

without a diagnostic alarm, the

calibration gases could be the

same or the calibration gas

was not turned on.

A flashing CAL LED indicates

the calibration is done. (See

Section 8, TROUBLE-

SHOOTING, for an explana-

tion of the 2 pattern and 3

pattern flashes).

7 Remove the second calibra-

tion gas and cap off the cali-

bration gas port.

8 Push the CAL key; the CAL

LED will be on solid as the

unit purges. (Default purge

time is three minutes). When

the purge is complete, the

CAL LED will turn off and the

Hazardous Area Oxymitter

4000 output unlocks from its

held value and begins to read

the process O2.

If the calibration was valid, the

DIAGNOSTIC ALARMS LEDs will

indicate normal operation. If either

new calibration value (slope or

constant) is not within parameters,

the DIAGNOSTIC ALARMS LED

will indicate an alarm. (See Section

8, TROUBLESHOOTING, for alarm

codes). If the calibration was inva-

lid, the Hazardous Area Oxymitter

4000 will return to normal opera-

tion, as it was before a calibration

was initiated, and the parameters

will not be updated.

Use heat-resistant gloves and clothing

when removing the probe. Do not at-

tempt to work on these components

until they have cooled to room tem-

perature. Probe components can be as

hot as 300°C (572°F). This can cause

severe burns.

Disconnect and lock out power before

working on any electrical components.

There is voltage of up to 115 VAC.

Do not remove the cell unless certain

it needs to be replaced. Removal may

damage the cell and platinum pad. Go

through the complete troubleshooting

procedure to make sure the cell needs

to be replaced before removing it.

1. Follow the instructions in paragraph

9-4a to remove the Hazardous Area

Oxymitter 4000 from the stack or duct.

3. Remove the locking set screw from the

flame arrestor. Use spanner wrenches

from the probe disassembly kit (Table

11-1) to turn the flame arrestor hub

free from the probe flange. If equipped

with the flame arrestor with ceramic

diffuser, remove and discard the

setscrews and remove the vee deflec-

tor (Figure 9-10). Inspect the ceramic

diffuser. If damaged, replace using

paragraph 9-4i.

4. Loosen the four socket head cap

screws from the cell and flange as-

sembly. Remove the assembly and the

corrugated seal. The cell flange has a

notch that may be used to gently pry

the flange away from the probe. Note

that the contact pad inside of the probe

will sometimes fuse to the oxygen

sensing cell. If the cell is fused to the

contact pad, push the cell assembly

back into the probe (against spring

pressure) and quickly twist the cell as-

sembly. The cell and contact pad

should separate. If the contact pad

stays fused to the cell, a new con-

tact/thermocouple assembly must be

installed. Disconnect the orange cell

wire at the probe electronics end of the

strut by cutting the wire. Withdraw the

cell with the wire still attached.

5. Remove entire electronics per para-

graph 9-4b, steps 2 and 3.

6. If the contact and thermocouple

assembly is damaged, replace the

assembly or the contact pad. Refer to

paragraph 9-4j to replace the contact

and thermocouple assembly. Instruc-

tions for replacing the contact pad are

in the cell replacement kit.

7. Remove and discard the corrugated

seal. Clean the mating faces of the

probe tube and cell. Remove burrs and

raised surfaces with a block of wood

and crocus cloth. Clean the threads on

the probe flange and flame arrestor

hub.

8. Apply a light coating of anti-seize

compound to both sides of the new

corrugated seal.

9. Assemble the cell and flange assembly

and corrugated seal to the probe tube.

Make sure the calibration tube lines up

with the calibration gas passage in

each component. Apply a small

amount of anti-seize compound to the

screw threads and use the screws to

secure the assembly. Torque to 4 N·m

(35 in-lbs).

10. Apply anti-seize compound to the

probe threads, flame arrestor hub, and

setscrews. Reinstall the flame arrestor

on the probe. Using pin spanner

wrenches, torque to 14 N·m (10 ft-lbs).

Secure the flame arrestor with the

locking setscrew. Torque to 2.8 N·m

(25 in-lbs). If applicable, reinstall the

vee deflector, orienting apex toward

gas flow. Secure with the setscrew and

anti-seize compound. Torque to 2.8

N·m (25 in-lbs).

11. On systems equipped with an abrasive

shield, install the dust seal gaskets,

with joints 180° apart.

12. If previously removed, install the entire

electronics per paragraph 9-4b, steps

4 and 5.

13. Follow the instructions in paragraph

2-1b to install the Hazardous Area

Oxymitter 4000 into the stack or duct. If

there is an abrasive shield in the stack,

make sure the dust seal gaskets are in

place as they enter the 15° reducing

cone.

i. Ceramic Diffusion Element Replacement

NOTE

This procedure applies to the ceramic

diffuser element only.

1. General

The diffusion element protects the O2

cell from particles in process gases.

The element does not normally need to

be replaced, because the vee deflector

protects it from particulate erosion. In

severe environments, the filter may be

broken or subject to excessive erosion.

Examine the ceramic diffusion element

whenever removing the probe for any

purpose. Replace if damaged.

Damage to the diffusion element may

become apparent during calibration.

Compare probe response with previous

response. A broken diffusion element

will cause a slower response to cali-

bration gas.

Hex wrenches needed to remove

setscrews and socket head screws in

the following procedure are available

as part of a Probe Disassembly Kit,

Table 11-1.

2. Replacement Procedure

(a) Follow the instructions given in

paragraph 9-4a to remove the

Hazardous Area Oxymitter 4000

from the stack or duct.

(b) Loosen setscrews, Figure 9-10,

using hex wrench from Probe

Disassembly Kit, Table 11-1 and

remove vee deflector. Inspect

setscrews. If damaged, replace

with stainless setscrews coated

with anti-seize compound.

(c) On systems equipped with abra-

sive shield, remove dual dust seal

gaskets.

(d) Use spanner wrenches from the

Probe Disassembly Kit, Table

11-1, to turn hub free from retainer.

(e) Put the hub in vise. Break out old

ceramic diffusion element with

chisel along cement line and 9.5

mm (3/8 in.) pin punch through

cement port.

(f) Break out remaining ceramic diffu-

sion element by tapping lightly

around hub with hammer. Clean

grooves with pointed tool if neces-

sary.

(g) Replace ceramic diffusion element

using the ceramic diffusion ele-

ment replacement kit in Table

11-1. This consists of a diffusion

element, cement, setscrews, anti-

seize compound and instructions.

(h) Test fit replacement ceramic diffu-

sion element to be sure seat is

clean.

Do not get cement on ceramic diffu-

sion element except where it touches

the hub. Any cement on ceramic diffu-

sion element blocks airflow through

element. Wiping wet cement off of the

ceramic only forces cement into

pores. Also do not get any cement

onto the flame arrestor element.

(i) Thoroughly mix cement and insert

tip of squeeze bottle into cement

port. Tilt bottle and squeeze while

simultaneously turning ceramic

should extrude from opposite hole.

Wipe excess material back into

holes and wipe top fillet of cement

to form a uniform fillet. (A Q-Tip is

useful for this.) Clean any excess

cement from hub with water.

(j) Allow filter to dry at room tem-

perature overnight or 1 to 2 hours

at 93°C (200°F).

(k) Wipe a heavy layer of anti-seize

compound onto the threads and

mating surfaces of the flame arre-

stor, diffusion hub, and probe tube.

(l) Assemble flame arrestor and diffu-

sion hub with two pin spanner

wrenches. Torque to 14 N·m (10 ft-

lbs). Secure with hub retaining

setscrew.

(m) On systems equipped with abra-

sive shield, install dust seal gas-

kets with joints 180° apart.

(n) Reinstall vee deflector, orienting

apex toward gas flow. Apply anti-

seize compound to setscrews and

tighten with hex wrench.

(o) Reinstall probe on stack flange.

OPTIONAL ACCESSORIES

HART HANDHELD 375 COMMUNICATOR

The HART Handheld 375 Communicator is an interface device

that provides a common communication link to HART-compatible

instruments, such as the Oxymitter 4000. HART Communica-

tions Protocol permits all the information available from the

Oxymitter 4000’s electronics to be transmitted over standard

4-20 mA signal wires. By attaching the HART handheld commu-

nicator at a termination point along the 4-20 mA signal line, a

technician can diagnose problems and configure and calibrate

the Hazardous Area Oxymitter 4000 as if he or she were stand-

ing in front of the instrument.

For more information, call Rosemount Analytical at

1-800-433-6076.

BY-PASS PACKAGES

The specially designed Rosemount Analytical By-Pass Package

for oxygen analyzers has proven to withstand the high tempera-

tures in process heaters while providing the same advantages

offered by the in situ sensor. Inconel or Kanthal steel tubes pro-

vide effective resistance to corrosion, and the package uses no

moving parts, air pumps, or other components common to other

sampling systems.

IMPS 4000 INTELLIGENT MULTIPROBE TEST

GAS SEQUENCER

The IMPS 4000 Intelligent Multiprobe Test Gas Sequencer

is housed within an IP56 (NEMA 4X) enclosure and has the

intelligence to provide calibration gas sequencing of up to four

Hazardous Area Oxymitter 4000 units to accommodate auto-

matic and semi-automatic calibration routines.

This sequencer works in conjunction with the Hazardous Area

Oxymitter 4000 CALIBRATION RECOMMENDED feature,

eliminating out-of-calibration occurrences and the need to send

a technician to the installation site. In addition, the SPS 4000

provides a remote contact input to initiate a calibration from a

remote location and relay outputs to alert when a calibration is in

progress, a Hazardous Area Oxymitter 4000 is out of calibration,

calibration gases are on, or calibration gas pressure is low.

For more information, call Rosemount Analytical at

1-800-433-6076.

SPS 4000 SINGLE PROBE

AUTOCALIBRATION SEQUENCER

Rosemount Analytical specifically designed the SPS 4000 Single

Probe Autocalibration Sequencer to provide the capability to

perform automatic or on-demand Oxymitter 4000 calibrations.

The SPS 4000 system must be installed a remote, safe area

if the Hazardous Area Oxymitter 4000 probe is installed in a

hazardous area.

The SPS 4000 works in conjunction with the Oxymitter 4000’s

CALIBRATION RECOMMENDED feature, eliminating out-of-

calibration occurrences and the need to send a technician to the

installation site. In addition, the SPS 4000 provides a remote

contact input to initiate a calibration from a remote location and

relay outputs to indicate when a calibration is in progress or the

Hazardous Area Oxymitter 4000 is out of calibration.
