A list of accessories for use with the OCX 8800 is provided in Table 1-2.

SYSTEM OVERVIEW Scope

This Instruction Manual supplies details needed to install, startup, operate,

and maintain the OCX 8800. Signal conditioning electronics outputs separate

4-20 mA signals representing oxygen (O2) and combustibles (COe) values.

This information, plus additional details, can be accessed with the HART

Model 275/375 handheld communicator or Rosemount Analytical AMS

software. The local operator interface (LOI) also provides a communications

interface with the electronics.

System Description

The OCX 8800 is designed to measure oxygen and combustible

concentrations in flue gas temperatures up to 2600°F (1427°C). Electrical

connections, power and communications are made through two 3/4 NPT ports

in the flameproof electronics enclosure using fittings and cables provided by

the customer. Cable installation must meet NEC, IEC and/or other applicable

national or local codes for Class I, Zone 1, Group IIB +H2 T3/T6 permanently

mounted equipment. The transmitter is close coupled to the process and

requires minimal sample conditioning requirements.

OCX 8800

The equipment measures oxygen percentage 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 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 oxygen in the measured gas on one side

of the cell.

2. P1 is the partial pressure of the oxygen in the reference air on the

opposite 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 instrument air (20.95% oxygen) as the

reference air.

When the cell is at operating temperature and there are unequal oxygen

concentrations 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 OCX 8800 to provide

exceptional sensitivity at low oxygen concentrations.

The OCX 8800 measures net oxygen concentration in the presence 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.

The OCX 8800 combustibles sensor is a catalytic sensor consisting of two

Resistance Devices (RTD). One RTD is the reference element covered with

an inert coating. The other RTD element is active, coated with a catalyst. As

the sample gases flow by the sensor, the combustible gases oxidize on the

surface of the active element. The oxidation that occurs produces heat and a

temperature rise in the active element. The temperature difference produces

a resistance relationship between the two elements that is directly

proportional to the concentration of combustibles in the sample gases.

The catalyst is specifically designed to detect carbon monoxide (CO), but the

sensor responds to other combustible gases. The sensor is calibrated using

CO, thus the output should be expressed in terms of CO. However, since the

sensor detects other combustible gases, the output cannot just be labeled

CO. The response of the sensor to other combustible gases gives an output

that is equivalent to the sensor detecting CO. The term COe is used in this

manual to describe the sensor output. This term indicates that the sensor is

calibrated in terms of CO, and that the sensor output is equivalent to CO but

not specific to CO.

Dilution air is provided to the COe sensor to ensure there is adequate oxygen

to fully oxidize any combustible gases regardless of the concentration of

oxygen in the process.

System Configuration

Transmitters are available in four lengths, giving the user the flexibility to use

a penetration appropriate to the size of the stack or duct. The length options

are 18 in. (457 mm), 3 ft (0.91 m), 6 ft (1.83 m), or 9 ft (2.7 m). Probes are

available in three material options, 316L stainless steel, inconel 600, and

ceramic to accommodate higher temperatures.

The electronics are contained in a separate housing from the sensors. The

electronics and sensor housings are integrally mounted.

The electronics control both sensor temperatures and provide individual 4-20

mA isolated outputs that are proportional to the measured oxygen and

combustibles concentrations. The power supply can accept voltages of 100 to

240 VAC and 50 to 60 Hz. The electronics accepts millivolt signals generated

by the sensors and produces the outputs to be used by remotely connected

devices. The outputs are isolated 4-20 mA linearized currents. Refer to

Section 3, Configuration and Startup for specific instructions upon initial

power up.

System Features

1. The O2 cell output voltage and sensitivity increase as the oxygen

concentration decreases.

2. HART communication is standard. To use the HART capability, you

must have either:

a. HART Model 275/375 Communicator.

b. AMS software for the PC.

3. Oxygen cell and heater/thermocouple assembly are field replaceable.

4. Electronics are automatically configured for line voltages from 100 to

240 VAC.

5. An operator can calibrate and diagnostically troubleshoot the OCX 8800

in one of two ways:

a. LOI. The LOI is mounted to the end of the electronics module and

allows local communications with the electronics. Refer to Section 4,

Using the LOI, for more information.

b. Optional HART Interface. Each of the OCX 8800's 4-20 mA output

lines transmit an analog signal proportional to oxygen or combustible

levels detected. The HART output is superimposed on the oxygen

4-20 mA output line only. This information can be accessed through

the following:

• Model 275/375 Handheld Communicator - The handheld

communicator requires Device Description (DD) software specific

to the OCX 8800. The DD software will be supplied with many

Model 275/375 units, but can also be programmed into existing

units at most Emerson Process Management service offices.

Refer to Section 5, Using HART Communications, for additional

information.

• Personal Computer (PC) - The use of a personal computer

requires AMS software available from Emerson Process

Management.

• Selected Distributed Control Systems - The use of distributed

control systems requires input/output (I/O) hardware and AMS

software which permit HART communications.

6. Optional Blowback System. The blowback system periodically blows

instrument air back through the sample line filter and out the sample

tube. This clears out particulate and keeps the sample line filter from

clogging.

System Operation

Figure 1-2 shows the relationship between the components of the OCX 8800.

The sensors and the electronics are contained in separate housings. The

sensor housing and probe mounts to a duct or process wall so that the probe

protrudes into the flue gas stream. An air powered eductor continuously pulls

samples of the process flue gas through the probe to a chamber in front of the

sensor housing where the sample passes the O2 sensor and continues on to

the COe sensor. Dilution air is provided to the COe sensor and reference air

to the O2 sensor. After the gas sample flows past the O2 sensor and through

the COe sensor, it is drawn through the eductor where it mixes with the

eductor air and exits through exhaust back into the system. The electronics

housing contains the CPU and HART boards which convert the sensor inputs

into 4-20 mA analog output signals. The CPU can also initiate and perform

calibrations. Three test gasses and instrument air can be turned on and off by

solenoids. Test gas flow to the sensors is regulated by a flow meter between

the electronics and sensor housings. Instrument air is separated into eductor

air, reference air, and dilution air. The instrument air solenoid does not allow

air flow until the heaters are up to temperature. This minimizes the amount of

sampled process flue gas being pulled into cold sensors causing

condensation.

It is important that printed circuit boards and integrated circuits are handled only when

adequate antistatic precautions have been taken to prevent possible equipment damage.

The OCX 8800 is designed for industrial application. Treat each component of the system

with care to avoid physical damage. The probe may contain components made from

ceramics, which are susceptible to shock when mishandled.

OCX 8800

After verifying that you have all the components, select mounting locations

and determine how each component will be placed in terms of available line

voltage, ambient temperatures, environmental considerations, convenience,

and serviceability. Figure 1-3 shows a typical system wiring. Simplified

installations for the OCX 8800 are shown in Figure 1-4.

A source of instrument air is required at the OCX 8800 for reference air,

dilution air, and eductor air. Since the OCX 8800 is equipped with an in-place

calibration feature, provision should be made for connecting test gas tanks to

the OCX 8800 when it is to be calibrated.

NOTE

The electronics module is designed to meet NEMA 4 (IP66) and the electronic

components are rated to temperatures up to 185°F (85°C).

Retain packaging in which the unit arrived from the factory in case any

components are to be shipped to another site. This packaging has been

designed to protect the product.

MECHANICAL

INSTALLATION

Selecting Location

1. The location of the OCX 8800 in the stack or flue is most important for

maximum accuracy in the oxygen analyzing process. The probe must

be positioned so the gas it measures is representative of the process.

Best results are normally obtained if the transmitter is positioned near

the center of the duct (40-60% insertion). Longer ducts may require

several transmitters since the oxygen and combustibles 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

process gas temperature falls within the range of probe material used.

Figure 2-1 through Figure 2-3 provide mechanical installation

references. The ambient temperature inside the electronics housing

must not exceed 185°F (85°C).

2. Check the flue or stack for holes and air leakage. The presence of this

condition will substantially affect the accuracy of the oxygen and

combustibles readings. Therefore, either make the necessary repairs or

install the transmitter up stream of any leakage.

3. Ensure the area is clear of internal and external obstructions that will

interfere with installation and maintenance access to the unit. Allow

adequate clearance for the removal of the OCX 8800.

Installation

1. Ensure all components are available to install the OCX 8800.

2. The OCX 8800 may be installed intact as it is received.

3. Weld or bolt adapter plate (Figure 2-2) onto the duct.

Do not allow the temperature of the electronics housing to exceed 185°F (85°C) or damage

to the electronics may result.

Whenever a positive stack pressure exists at the installation site, be sure to connect all

pneumatic lines prior to installing the OCX 8800 in the stack or ductwork. Failure to connect

the pneumatic lines can allow the flow of contaminants into the OCX 8800 ports.

Before installing the OCX 8800 into a hot stack or ductwork, make sure that the OCX 8800

is turned on and at normal operating temperature. Exposing a cold OCX transmitter to hot

process gases can cause permanent damage to the equipment.

Instruction Manual

IM-106-880, Rev 1.0

January 2007

2-3

OCX 8800

4. Ensure the conduits drop vertically from the OCX 8800 and the conduit

is routed below the level of the conduit ports on the housing to form a

drip loop. Drip loops minimize the possibility that moisture will damage

the electronics (Figure 2-3).

5. Where a positive stack pressure exists at the installation site, connect all

pneumatic lines prior to installing the OCX 8800 in the stack or

ductwork.

NOTE

If process temperatures will exceed 392°F (200°C), use anti-seize compound

on stud threads to ease future removal of the OCX 8800.

6. Insert sample and exhaust tubes through the opening in the mounting

flange and bolt the unit to the flange.

7. If insulation is removed to access the duct for OCX 8800 mounting,

make sure to replace insulation afterward.

Enclosures

The OCX 8800 enclosures are designed to meet ingress conditions of IP66.

Each enclosure cover is threaded to its base and sealed with an o-ring that

isolates the threads from external contaminants.

Each cover is secured by a clip attached to the base that engages the cover

between the ribs of the cover sidewall. The clip is held in place by an Allen

head cap screw and lockwasher mounted in a recess. Cover removal and

installation requires an Allen wrench to loosen and tighten the screw.

Uninsulated stacks or ducts may cause ambient temperatures in the electronics housing to

exceed 185°F (85°C) and damage the electronics.

PNEUMATIC

INSTALLATION

Pneumatic system connections depend on whether reference air set,

calibration solenoids, and/or blowback equipment options are equipped on

your transmitter. Refer to the following paragraphs and select the option that

applies to your transmitter configuration.

Reference Air Set Option (only)

When no options or only the reference air set option is equipped, use the

following procedure to install the pneumatic system components.

1. Refer to Figure 2-5. Connect the reference air set (regulator/filter and

pressure gage) to the instrument air inlet on the electronics housing and

to the inlet side of the dilution air flow meter.

2. Connect the dilution air flow meter output to the dilution air inlet fitting on

the sensor housing.

3. Install an air line between the instrument air outlet fitting on the

Reference Air Set, Solenoids, and Blowback Option

The blowback system blows instrument air back through the blowback filter

and out the sample tube of the transmitter. This removes built up dirt and

particulate from the filter and sample line. The blowback option is normally

used in systems that have a dirty process stream.

Installing an OCX 8800 with the blowback option requires the addition of air

operated blowback valve, regulator and gage, and check valve.

Figure 2-7 shows the piping arrangement for the OCX 8800 with the blowback

and autocalibration options. Figure 2-8 shows the piping arrangement for the

OCX 8800 with the blowback option, but without autocalibration (without test

gas solenoids).

When the reference air set, calibration gas solenoids, and blowback options

are included with your transmitter, use the following procedure to install the

pneumatic system components.

1. Connect the calibration gas sources according to the instructions in the

previous paragraph “Reference Air Set and Solenoids Option”, steps 2

through 5.

2. Connect a clean, dry, instrument-quality supply of air (20.95% O2) to the

35/45 psig and 55 psig pressure regulators. The inlet to the 35/45 psig

regulator accepts a 1/8" NPT fitting. The inlet to the 55 psig regulator

accepts a 1/4" NPT fitting.

3. See the upper leg of the instrument air supply. Connect the output of the

35/45 psi regulator/filter to one port of the normally-closed air-operated

solenoid valve, and to the inlet side of the dilution air flow meter.

4. Connect the dilution air flow meter output to the DILUTION AIR inlet

fitting on the sensor housing.

5. Install an instrument air line between the open port of the normally-open

air-operated solenoid valve and the tee fitting on the sensor housing.

6. Connect the output of the 55 psi regulator/filter to one port of the

normally-open air-operated solenoid valve, and to the instrument air

inlet on the back of the electronics housing.

7. Install an air line between the open port of the normally-closed

air-operated solenoid valve and the check valve inlet fitting on the

sensor housing.

Verify Configuration

There are three switches on the microprocessor board which are user

configurable for the OCX 8800 (Figure 3-1). SW1 determines if the O2 4-20

mA signal is internally or externally powered. SW2 determines if the COe 4-20

mA signal is internally or externally powered. SW3 sets the rail limits for the

O2 and COe 4-20 mA signals and configures the sample line heater control

circuit. All switches are accessible through holes in the electronics box.

Verify that the following switch settings are correct for your OCX 8800

installation:

SW1 The two settings are internally or externally powering the O2 4-20

mA signal. The factory setting is for the O2 4-20 mA signal to be internally

powered.

SW2 The two settings are internally or externally powering the COe 4-20

mA signal. The factory setting is for the COe 4-20 mA signal to be

internally powered.

SW3 The factory sets this switch as follows:

• Position 1 determines the O2 4-20 mA signal rail limit. The settings are

high, 21.1 mA, or low, 3.5 mA. The factory setting is low, 3.5 mA.

• Position 2 determines the COe 4-20 mA signal rail limit. The settings

are high, 21.1 mA, or low, 3.5 mA. The factory setting is high, 21.1 mA.

• Positions 3 and 4 must be set as shown for proper software control of

the device heaters.

Remove power from the OCX 8800 before changing defaults. If defaults are changed under

power, damage to the electronics may occur.

INITIAL POWER UP Allow adequate time (approximately 60 minutes) for the heaters to begin

operation and for the OCX 8800 to reach normal operating temperature on

power up. Normal operating temperature for the O2 cell is 736°C. Normal

operating temperature for the combustibles cell is 300°C. The normal sample

line temperature is 170°C. During this time the eductor air solenoid will remain

closed so no sample is pulled through the analyzer. When the OCX reaches

operating temperature the solenoid will energize, eductor air will begin to flow,

and the unit will begin normal operation.

LOI CONTROLS

Overview The LOI, shown in Figure 4-2, utilizes a bright blue gas-fluorescent display.

Intensity is adjustable. There is an Infrared 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 OCX 8800 also utilizes HART

communications, permitting access to all instrument functionality anywhere

the 4-20 mA signal terminates via a HART model 275/375 handheld

communicator.

Figure 4-2. LOI Assembly

LOI Key Functions The gray (top left) key will move one level higher in the menu structure. When

entering parameter values (numbers), this key moves the cursor to the left.

The left-pointing key also doubles as an Enter key, used after the digits of a

parameter value are entered, and the cursor is moved to its left-most position.

When the Enter key is touched, the new parameter value, if accepted, will

appear in the top line of the display.

The blue (bottom left) key acts as a selector when choosing from among

several menu items. This right-pointing key also will move the cursor to the

right when entering the digits of a new parameter value.

The up and down-pointing keys are used to increment up and down when

selecting from a vertical list of menu items. These keys are also used for

incrementing values up and down for new data input.

Lockout

The 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 established when no buttons are pushed for 30

seconds (default). This countdown to lockout is configurable.

In order to unlock the display, input a "Z" pattern (Figure 4-3). First, touch the

top left (gray) Enter key. Next, touch the top right key, followed by the bottom

left key and the bottom right key. The LK notation in the upper right corner of

the display will disappear. Touch the Enter key once more to enter into the

menu structure. Whenever a key is touched additional time to lockout is

provided, so that the lockout feature does not become a nuisance. This

additional revert time is one hour (default) and is also user configurable.

OVERVIEW The HART communicator is a handheld communications interface device. It

provides a common communications link to all microprocessor-based

instruments that are HART compatible. 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 specific functions

of all the keys.

To interface with the OCX 8800, the HART communicator requires a

termination point along the O2 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 4-20 mA oxygen output

signal. The communicator does not disturb the 4-20 mA signal since no net

energy is added to the loop. HART information is not available on the COe

output signal.

The HART communicator may be interfaced with a personal computer (PC),

providing 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.

HART COMMUNICATOR

SIGNAL CONNECTIONS

The HART communicator can connect to the OCX 8800 oxygen analog output

signal line at any wiring termination in the O2 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.

HART COMMUNICATOR

PC CONNECTIONS

There is an option to interface the HART communicator with a personal

computer. Load the 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 documentation in regard to the PC interface option.

Off-line and On-line Operations

The HART communicator can be operated both off-line and on-line.

Off-line operations are those in which the communicator is not connected to

the OCX 8800. Off-line operations can include interfacing the HART

communicator with a PC. (Refer to applicable HART documentation regarding

HART/PC applications.)

In the on-line mode, the communicator is connected to the oxygen 4-20 mA

analog output signal line. The communicator is connected in parallel to the

OCX 8800 or in parallel to the 250 ohm load resistor.

The opening menu displayed on the LCD is different for on-line and off-line

operations. When powering up a disconnected (off-line) communicator, the

LCD will display the Main Menu. When powering up a connected (on-line)

communicator, the LCD will display the On-line Menu. Refer to the HART

communicator manual for detailed menu information.

REPLACE TUBE

FITTINGS

The OCX transmitter housings have special tube fittings that, if clogged or

damaged, must be replaced with the same type of fitting. The special tube

fittings have alpha or numeric codes etched on the fitting. Unetched tube

fittings are standard 1/4 inch, stainless steel fittings.

‘F’ Type Fitting

The ‘F’ type fitting is a flame arrestor fitting used in all OCX 8800

hazardous area housings. The flame arrestor fitting prohibits spark or

flame conduction from the housing. It requires a thread sealing compound

(Loctite 567) and at least five threads engagement.

‘13’ Type Fitting

This fitting is an eductor drive air fitting for the OCX 8800 hazardous area

housing. This is a 1/8 inch tube fitting with a built-in 0.013 inch restrictor

orifice. It seats in a threaded base port inside the housing.

‘R’ Type Fitting

The ‘R’ type fitting is a reference air line fitting for the general purpose and

hazardous area sensor housings. This is a 1/4 inch tube fitting with a

built-in 0.007 inch restrictor orifice.

Remove Tube Fittings The OCX construction includes pipe thread sealant to seal fittings in all ports

that pass through to an outer wall of the instrument housing base. Use the

following instructions to loosen and remove tube fittings that are secured with

pipe thread sealant.

1. Secure sensor housing (1, Figure 7-25) or electronics housing (2) in soft

(plastic, wood, or brass) vice jaws.

2. To soften the pipe thread sealant, use a propane torch to heat the tube

fitting (3, 4, 5, or 6) to 450°F (232°C), minimum.

3. While heating the tube fitting, use a wrench to apply removal torque until

the pipe thread sealant softens. Remove and discard the used fitting.

4. Use MEK or methylene chloride solvent to clean thread sealant residue

from the internal pipe threads in the housing. Refer to applicable MSDS

sheet for solvent handling precautions.

Use heat resistant gloves when removing a damaged tube fitting. The pipe threads are

bonded with a pipe thread sealant. The thread sealant softens at 450°F (232°C). The

heated parts can cause severe burns.

OVERVIEW The troubleshooting section describes how to identify and isolate faults that

may develop in the OCX 8800. When troubleshooting the OCX 8800,

reference the following information.

Grounding It is essential that adequate grounding precautions are taken when installing

the system. 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 total elimination of ground loops.

Electrical Noise The OCX 8800 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.

Electrostatic Discharge Electrostatic discharge can damage ICs in the electronics. Before removing or

handling the processor board or the ICs, ensure you are at ground potential.

Install all protective equipment covers and safety ground leads after troubleshooting.

Failure to install covers and ground leads could result in serious injury or death.

Total Power Loss In the event that the OCX 8800 will not power up at all, check the incoming

power supply to make sure power is being delivered to the OCX 8800. If the

incoming power supply is good, then check fuses F1 and F6 in the electronics

housing. Refer to Figure 8-1 for fuse locations.

Figure 8-1. Fuse Locations

DIAGNOSTIC ALARMS

The OCX 8800 is equipped with a set of alarm relay contacts on the

microprocessor board in the electronics housing. This set of dry contacts can

be connected to any customer supplied relay device, 30 VDC, 30 mA

maximum. A blocking diode is required on the customers relay coil.

Any fault condition in the OCX 8800 will trip the alarm relay. The optional SPA

with HART programmable alarm indicates LOW O2, HIGH COe, Calibration

Status, and Unit Failure. For more information refer to Appendix B - SPA with

HART Alarm.

FAULT ISOLATION Faults in the OCX 8800 Transmitter are indicated by messages displayed on

the HART communicator or LOI. Fault indications that can appear are listed in

Table 8-1, Troubleshooting.

If a fault is indicated on the HART communicator or LOI, locate the fault

indication in Table 8-1. For each fault listed, there are related Probable

Causes and Recommended Corrective Actions. The Probable Causes are

listed in the order of most probable to least probable. Starting with the most

probable cause, inspect and test the unit to isolate the actual cause, then use

the Recommended Corrective Action listed to correct the problem.

Table 8-1. Troubleshooting

O2 Sensor R High (Oxygen sensor resistance high, > 5000 Ohms)

O2 Sensor Open (Oxygen sensor disconnected)

Probable Cause Recommended Corrective Action

Loose or open O2 cell circuit connection Check O2 cell circuit wires for breaks or loose connections. Repair lead wire break or

loose connections.

O2 cell degraded or failed Check O2 cell impedance by reading the O2 Cell Imped value via the LOI (see

Figure 4-4, sheet 2), or the O2 Snsr R value via HART (see Figure 5-3, sheet 2). If cell

impedance is zero, replace O2 cell with cell replacement kit. If cell impedance is less

than 5000 ohms, check for cell housing ground fault. Repair ground fault. If cell

impedance is greater than 5000 ohms and no ground fault is indicated, replace O2 cell

with cell replacement kit.

vastavate oskustega spetsialisti poolt.

8. Seadmele või ümbristele märgitud paremale osutava

sümboli all valitseb kuumadest pindadest tulenev oht.

Nimetatud sümbolitega ümbriseid võib eemaldada vaid

vastavate oskustega spetsialist, kui seade on

toiteallikast lahti ühendatud. Teatud pinnad võivad

puudutamise jaoks liiga kuumad olla.

9. Seadmel või ümbristel leiduva paremale osutava

sümboli korral vt juhiste jaoks Toimimisjuhendit.

10. Kõik selle toote juures kasutatavad graafilised sümbolid

lähtuvad ühest või enamast järgmistest standarditest:

EN61010-1, IEC417 ja ISO3864.

11. Kui seadmele või siltidele on kirjutatud "Ärge avage voolutarbimine

korral" vms, valitseb plahvatusohtlikus keskkonnas süttimise oht.

Seadet võib avada ainult siis, kui toide on lahti ühendatud ning seadmel

on võimaldatud sildil või kasutusjuhendis osutatud aja jooksul maha

jahtuda -- ning ka sellisel juhul ainult vastavate oskustega spetsialisti

poolt.

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

(Pneumoconiosis). 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 updated 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

developed masotheliomas.

Instruction Manual

IM-106-880, Rev 1.0

OCX 8800

The International Agency for Research on Cancer (IARC) reviewed the

carcinogenicity data on man-made vitreous fibers (including ceramic

fiber, glasswool, rockwool, and slagwool) in 1987. IARC classified

ceramic fiber, 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 applicable Federal, State, and Local

regulations.

Instruction Manual

IM-106-880, Rev 1.0

January 2007

OCX 8800

A-28

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 suitable equipment).

Pending the results of long term health effects studies, engineering

control of airborne fibers to the lowest levels 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 formaldehyde may accompany binder burn off during first heat. Use

adequate ventilation or other precautions to eliminate 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 prevent fiber transfer to street

clothes. Wash work clothes separately from other clothing and rinse

washing machine 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 described 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 minimize generation of airborne

dust.

It is recommended that full body clothing be worn to reduce the potential

for skin irritation. Washable or disposable 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 1800°F/982°C) 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.

Instruction Manual

IM-106-880, Rev 1.0

January 2007

A-29

OCX 8800

IARC has recently reviewed the animal, human, and other relevant

experimental data on silica in order to critically 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 protection recommended

for given airborne fiber or cristobalite concentrations are:

CONCENTRATION

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 evaporates 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 surfactant 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.

is in the ON position, reposition the jumper.

3. Check the position of the Failsafe Dip Switches. Position the dip

switches as shown in Figure B-3.

4. Check the position of the Source Current Dip Switches. Position the dip

switches as shown in Figure B-3.

5. Reinstall the SPA access cover.

Configuration/Calibration

Prior to operation, the SPA operating parameters must be configured via a

menu-driven setup procedure. At the end of the configuration procedure, the

SPA analog output signal is calibrated to insure valid communications.

1. See Figure B-4. Connect a calibrated ammeter (Fluke Model 87 or

equivalent, accurate to ±0.025%) to the SPA analog output terminals.

Observe polarity.

2. Connect a 90 to 260 VAC or 22 to 300 VDC power source to the SPA

power terminals. When connecting an AC power source, use the AC

and ACC (AC Common) terminals. For a DC source, use the AC and

Ground terminals.

3. If desired, you can connect the 4 to 20 mA O2 signal wires from the

OCX 8800 analog output terminal block to the SPA Input terminals. (The

OCX must be operational to transmit the O2 signal. Observe polarity.)

WARRANTY

Rosemount Analytical warrants that the equipment manufactured and sold by it

will, upon shipment, be free of defects in workmanship or material. Should any

failure to conform to this warranty become apparent during a period of one year

after the date of shipment, Rosemount Analytical shall, upon prompt written notice

from the purchaser, correct such nonconformity by repair or replacement, F.O.B.

factory of the defective part or parts. Correction in the manner provided above

shall constitute a fulfillment of all liabilities of Rosemount Analytical with respect to

the quality of the equipment.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER

WARRANTIES OF QUALITY WHETHER WRITTEN, ORAL, OR IMPLIED

(INCLUDING ANY WARRANTY OF MERCHANTABILITY OF FITNESS FOR

PURPOSE).

The remedy(ies) provided above shall be purchaser's sole remedy(ies) for any

failure of Rosemount Analytical to comply with the warranty provisions, whether

claims by the purchaser are based in contract or in tort (including negligence).

Rosemount Analytical does not warrant equipment against normal deterioration

due to environment. Factors such as corrosive gases and solid particulates can

be detrimental and can create the need for repair or replacement as part of normal

wear and tear during the warranty period.

Equipment supplied by Rosemount Analytical Inc. but not manufactured by it will

be subject to the same warranty as is extended to Rosemount Analytical by the

original manufacturer.

At the time of installation it is important that the required services are supplied to

the system and that the electronic controller is set up at least to the point where it

is controlling the sensor heater. This will ensure, that should there be a delay

between installation and full commissioning that the sensor being supplied with ac

power and reference air will not be subjected to component deterioration.
