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 a 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 pressurized system.

7. No part of cylinder should be subjected to a temperature higher than 125

°

F (52

°

C). 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.

SECTION 1

DESCRIPTION AND SPECIFICATIONS

1-1 GENERAL DESCRIPTION

The Model 890 Ultraviolet Analyzer is

designed to determine continuously the

concentration of the component of interest

in

a flowing gaseous mixture. The analyzer is

capable of measurement in the 50 to 5,000

ppm range for SO

2

and 100 to 5,000 ppm for

Cl

2

.

Optical Bench

The ultraviolet source emits a pulsed (30 Hz)

beam of energy. This energy is split by a

beam splitter, each beam being directed to

pairs of detectors before and after the sample

cell.

One of the unique features of the Model 890

is the use of spectrally selective,

“Transflectance”© mirrors. These mirrors

isolate the sample and reference spectral

passbands for the detectors. They reflect

energy below a wavelength region and

transmit the remaining, higher wavelengths,

all with much lower energy loss than the more

commonly used bandpass interference filters.

Four detectors are used in this system, two

before the sample cell (sample before [S

b]

and reference before [R

b]) and two after

(sample after [Sa] and reference after [Ra]).

S

b and Sa receive energy in the specific

wavelength regions depending on the

application (265 to 310 nm for SO

2

, 310 to

355 nm for Cl

2

), Rb and Ra in the 310 to 355

nm region for SO

2

and 355 to 400 nm for Cl

2

.

These four detectors measure the component

of interest (COI) concentration and correct for

NO

2 interference and UV lamp fluctuations.

The difference between detector

determinations is the COI concentration,

following this formula:

COI = [f(R

b)-Sb]-[f(Ra)-Sa]

where:

Ra, Rb, Sa, Sb = signals from those

detectors so identified

f = attenuation factor for the reference

signal, adjusted to compensate for NO

2

interference.

The sample gas is introduced to the sample

cell, and the COI absorbs ultraviolet energy in

proportion to the concentration in the gas. The

difference between the signals of the

detectors located at both ends of the sample

cell determines the concentration of COI

in

the sample.

Additionally, the adjacent (non-COI

-

absorbing) reference wavelengths are used

as a baseline for measurement and correction

of sample interferent components, particularly

NO

2.

Readout is on a 16-character,

LED-backlighted liquid crystal display. COI

concentration data is presented in parts per

million, percent of composition, or percent of

fullscale. Additionally, 0 to +5 VDC output for

a potentiometric (voltage) recorder and 0 to

20 mA or 4 to 20 mA isolated current output

(maximum load 700 ohms) are provided as

standard.

A case heater with fan assembly maintains

proper operating temperature.

Linearization

A linearizer, based on a fourth-order

polynomial, is incorporated in the electronic

circuitry. By turning the linearizer ON and

entering the correct coefficients, an output

linear with concentration is obtained.

SECTION 2

INSTALLATION

2-1 CHECK FOR SHIPPING DAMAGE

Examine the shipping carton and contents

carefully for any signs of damage. Save the

carton and packing material until the analyzer

is operational. If carton or contents damage

(either external or concealed) is discovered,

notify the carrier immediately.

2-2 LOCATION

Locate the analyzer in a weather-protected,

non-hazardous location free from vibration.

For best results mount the analyzer near the

sample stream to minimize sample-transport

time. Refer to Installation Drawing 654853.

If equipped with PN 624446 optional air purge

kit and installed with user-provided

components per Instructions 748157, the

analyzer may be located in a Class I, Division

2 area as defined by the National Electrical

Code (ANSI/NFPA 70). This kit is designed to

provide Type Z protection in accordance with

Standard ANSI/NFPA 496-1993, Chapter 2,

when sampling nonflammable gases. For

flammable samples, the instrument must be

equipped with a continuous dilution purge

system in accordance with ANSI/NFPA

496-1993, Chapter 6. Consult factory for

recommendations concerning minimum purge

flow requirements for your particular

application.

2-3 VOLTAGE REQUIREMENTS

WARNING

ELECTRICAL SHOCK HAZARD

For safety and proper performance this in-

strument must be connected to a properly

grounded three-wire source of electrical

power.

This instrument was shipped from the factory

set up to operate on 115 VAC, 50/60 Hz

electric power. For operation on 230 VAC,

50/60 Hz the installer must position voltage

select switches S1 and S2 located on power

supply board to the 230 VAC position (see

Figure 2-1 on page 2-2).

Power consumption is 350 watts.

2-4 ELECTRICAL CONNECTIONS

The power, recorder and current output cable

glands are shipped already installed to allow

attachment of cables to connectors or terminal

strips. Cable glands for specific cables are as

follows:

CABLE GLAND PART NO.

Power 899330

Recorder 899329

Current Output 899329

Remove the rear cover to access the

terminals. Route each cable through the

cable gland and connect to appropriate

connector or terminal strip as shown in

Drawings 654853 and 652715. Then, tighten

the gland.

a. Line Power Connections

If this instrument is located on a bench or

table top or is installed in a protected

rack, panel or cabinet, power may be

connected to it via a 3-wire flexible power

cord, minimum 18 AWG (max. O.D.

0.480", min. O.D. 0.270") through hole

“F” (refer to Drawing 654853) utilizing the

connector gland (PN 899330) provided.

Accessory kits are available which include

one of the following: 1) a 10-foot North

American power cord set and four

enclosure support feet (PN 654008) for

bench top use, 2) the power cord only

(PN 634061), or 3) the four feet only (PN

634958). If the instrument is permanently

mounted in an open panel or rack, use

electrical metal tubing or conduit.

2-2 Installation Rosemount Analytical Inc. A Division of Emerson Process Management

Model 890

Refer to Figure 2-2 on page 2-3 and

Drawings 654853, 652715 and 656139.

Route the power cable through the cable

gland and connect the leads to TB1. After

connecting the leads, tighten the cable

gland adequately to prevent rotation or

slippage of the power cable. Since the

rear terminals do not slide out with the

chassis, no excess power cable slack is

necessary.

b. Recorder Connections

Recorder connections are made to the

rear panel. Refer to Drawings 654853,

652715 and 656139. Route the recorder

cable through the cable gland and

connect to TB2.

Recorder and interconnection cables

should meet the following requirements:

Voltage Output: 0 to +5 VDC

•

Maximum distance from recorder to

analyzer: 1000 ft. (305 m)

•

Recorder input impedance: >5000

ohms

•

Customer-supplied cable:

2-conductor, 20 AWG (min.), shielded

Isolated Current Output: 0 to 20 mA or

4 to 20 mA (keyboard programmable)

•

Maximum load impedance: 700 ohms
