Important Notice

This instrument provides measurement readings to its user, and serves as a tool by which
valuable data can be gathered. The information provided by the instrument may assist the user
in eliminating potential hazards caused by his process; however, it is essential that all
personnel involved in the use of the instrument or its interface, with the process being
measured, be properly trained in the process itself, as well as all instrumentation related to it.

The safety of personnel is ultimately the responsibility of those who control process
conditions. While this instrument may be able to provide early warning of imminent
danger, it has no control over process conditions, and it can be misused. In particular, any
alarm or control systems installed must be tested and understood, both as to how they
operate and as to how they can be defeated. Any safeguards required such as locks, labels,
or redundancy, must be provided by the user or specifically requested of TI/AI at the time
the order is placed.

Therefore, the purchaser must be aware of the hazardous process conditions. The purchaser
is responsible for the training of personnel, for providing hazard warning methods and
instrumentation per the appropriate standards, and for ensuring that hazard warning devices
and instrumentation are maintained and operated properly.

Teledyne Instruments/ Analytical Instruments, the manufacturer of this instrument, cannot
accept responsibility for conditions beyond its knowledge and control. No statement
expressed or implied by this document or any information disseminated by the
manufacturer or its agents, is to be construed as a warranty of adequate safety control under

3.1. Unpacking and Initial Setup

CAUTION: TO AVOID PERSONAL INJURY, ALWAYS USE TWO

PERSONS TO LIFT AND CARRY THE MODEL
6400EH.

1. Inspect the received packages for external shipping damage. If

damaged, please advise the shipper first, then TAI.

2. Included with your analyzer is a printed record of the final

performance characterization performed on your instrument at
the factory. This record is an important quality assurance and
calibration record for this instrument. It should be placed in the
quality records file for this instrument.

3. Carefully remove the top cover of the analyzer and check for

internal shipping damage.

 Remove the set screw located in the top, center of the rear

panel

 Remove the screws fastening the top cover to the unit (four

per side).

 Lift the cover straight up.

Note: Printed circuit assemblies (PCAs) are sensitive to electro-

static discharges too small to be felt by the human nervous
system. Failure to use ESD protection when working with
electronic assemblies will void the instrument warranty.

See Chapter 12 of the 6400E Manual (P/N 04515) for more
information on preventing ESD damage.

Zero Air

On Units with zero/span valve option installed, this port connects the zero air gas or the
zero air cartridge to the analyzer.

FUNCTION

Figure 3-5 of the 6400E Manual shows the internal pneumatic flow
of the 6400E in its standard configuration. For a diagram of the internal
pneumatic flow of the 6400EH, see Figure 3-2 of this manual.

3.2.2.1 PNEUMATIC CONNECTIONS TO 6400EH BASIC CONFIGURATION

The pneumatic connections for the 6400EH analyzer in its basic
configuration are nearly identical to those described the 6400E Manual
in Section 3.1.2.2 except that the 6400EH has an external pump.
Therefore:

 A pneumatic line of ¼” PTEF must be attached between the

analyzer’s exhaust port and the inlet port of the pump.

 The exhaust from must be vented outside the shelter or immediate

area surrounding the instrument using a maximum of 10 meters of
1/4” PTFE tubing.

3.3 Initial Operation

With the following exceptions, the operation of the 6400EH is
nearly identical to that of the 6400E. Please refer to the 6400E User’s
Manual, Chapter 3, for details on initial operation, including common
warning messages, functional checkout of the instrument, initial
calibration and common interferents for the 6400EH.

3.3.1 Warning Messages

Please refer to the 6400E User’s Manual, Chapter 3, for a complete
listing of warnings for the 6400EH. The following table lists warnings
that differ in the 6400EH from those described in the 6400E manual.

MESSAGE MEANING

Vacuum Pressure Warning

The vacuum pressure reading is out of it’s allowed range. The pump
may have failed, or the instrument may have a leak or obstruction in
the flow path.

3.3.2 Test Functions

Check to make sure that the analyzer is functioning within
allowable operating parameters As described in Section 3.2.4 of the
6400E Manual (P/N 04515). The available test functions for the 6400EH
is shown in Figure 3-5.

3.3.3 Interferents for SO

2 Measurements

Hydrocarbons are a significant interferent for UV fluorescent SO2
measurements, however, the typical 6400EH application does not have
hydrocarbons in the sample stream. Therefore, in order to reduce cost to
the customer, the 6400EH in its standard configuration does not include
a hydrocarbon kicker/scrubber.

If your application includes hydrocarbons in the sample gas stream,
it is very important that they be removed from the sample gas prior to
them entering the analyzer’s sample chamber. A hydrocarbon Kicker
Option (OPT 65) package (see Section 5 below) is available for this
purpose.

UV Fluorescence SO2 Analyzer FAQ

Frequently Asked Questions

Q: How long does the sample pump last?
A: The sample pump should last about one year and the pump

diaphragms should to be replaced annually or when
necessary.

To determine if the diaphragm on a 6400EH needs replacing check

the VAC test function (instead of the PRES function as described in the
6400E Manual). If the VAC value is > 10 in-Hg-A, the diaphragm should

be replaced.

Optional Hardware and Software

With the following additions, changes and exceptions, the options
listed in Chapter 5 of the 6400E Manual are also available for the
6400EH.

5.1 Zero/Span Valves (Option 50)

The 6400EH zero/span valve option is identical to that of the
6400E in respect to operation and valve states (see Table 5-1 of the
6400E Manual). The internal pneumatic connections are slightly
different.

5.2 Internal Zero/Span Gas Generator (Option 51)

The IZS valve option (OPT 51) is not available for the 6400EH.

5.3 Zero and Two Span Point Valve Option (OPT 52)

This option includes a special set of valves that allows two separate

SO

mixtures to enter the analyzer from two independent sources.

2

Typically these two gas mixtures will come from two, separate,
pressurized bottles of certified calibration gas: one mixed to produce a
SO2 concentration equal to the expected span calibration value for the
application and the other mixed to produce a concentration at or near the
midpoint of the intended measurement range. Individual gas inlets,
labeled HIGH SPAN and LOW SPAN are provided at the back on the
analyzer.

The valves allow the user to switch between the two sources via
keys on the front panel or from a remote location by way of either the
analyzer’s digital control inputs or by sending commands over it’s serial
I/O port(s). The pneumatic diagram for instruments with the zero and
two span point valve option (OPT 52) is shown in Figure 5-2.

Note: The analyzer’s software only allows the SLOPE and

OFFSET to be calculated when sample is being

routed through the HIGH SPAN inlet.
The LOW SPAN gas is for midpoint reference checks only.

5.4 Hydrocarbon Kicker Option (OPT 65)

This option is specifically designed for those applications where
hydrocarbons are present in the sample gas stream. It includes an
internal, scrubber consisting of a tube of a specialized plastic that
absorbs hydrocarbons very well located within an outer flexible plastic
tube shell.

As gas flows through the inner tube, hydrocarbons are absorbed
into the membrane walls and transported through the membrane wall and
into the hydrocarbon free, purge gas flowing through the outer tube (see
Figure 5-3). This process is driven by the hydrocarbon concentration
gradient between the inner and outer of the tubes.

Teledyne Analytical Instruments 22

UV Fluorescence SO2 Analyzer Optional Hardware/Software

Figure 5-3: Hydrocarbon Scrubber (Kicker) – OPT 65

The scrubbed air from the inner tube is returned to be used as the
purge gas in the outer tube after it passes through the analyzers reaction
cell. This means that when the analyzer is first started, the concentration
gradient between the inner and outer tubes is small and the scrubber’s
efficiency is relatively low. When the instrument is turned on after
having been off for more than 30 minutes, it takes a certain amount of
time for the gradient to become large enough for the scrubber to
adequately remove hydrocarbons from the sample air.

UV Fluorescence SO2 Analyzer Calibration and Check

Calibration and Calibration Check Procedures

Calibration procedures for the 6400EH are the same as those for the
6400E. One exception to this statement is that the 6400EH has a special
valve option, Zero and Two Span Point Valve Option - OPT 52 (See
Section 5.1), that allows a mid-span point be checked.

7.1 Manual Calibration with the Zero and Two Span

Point Valve Option (OPT 52) installed

Note: It is only possible to calibrate to the high span gas. The low

span gas is only used for calibration checks.

Zero and Span calibrations using the Zero and two Span Valve
option are similar to that described in Section 7.2, except that:

 Zero air and both span gas is supplied to the analyzer through the

zero gas and span gas inlets rather than through the sample inlet.

 The zero and cal operations are initiated directly and

independently with dedicated keys (CALZ & CALS)

STEP ONE: Connect the sources of zero air and span gas to the

respective ports on the rear panel (see Figure 3-2 of this manual).

UV Fluorescence SO2 Analyzer Theory of Operation

Theory of Operation

9.1 The UV Light Path

The UV light path of the 6400EH is similar to that of the 6400E
(see Section 10.2 of the 6400E Manual). The main differences between
the 6400EH and the 6400E are:

 The location of the reference detector (See Section 9.1.1 of this

addendum).

 The methods used to reject for certain measurement interferents is

different (see Section 9.1.2 of this manual).

Figure 9-1: UV Light Path

Teledyne Analytical Instruments 37

Theory of Operation Model 6400EH

9.1.1 The Reference Detector

A vacuum diode UV detector that converts UV light to a DC
current is used to measure the intensity of the excitation UV source
lamp. The location of the 6400EH reference detector differs from that of
the 6400E.

 On the 6400E this detector is located directly across the reaction cell

from the lamp where it can measure the output of the lamp
directly. Because the 6400E is designed to measure relatively
low concentrations of SO

, enough of the lamp’s 214 nm source

2

light makes it through the reaction cell to get a reliable reading.

 On the 6400EH the detector is located between the UV lamp and the

reaction cell and to the side. A beam splitter reflects a portion of
the lamp output 90 degrees, through a window and onto the
detector. This arrangement is required because nearly all of 214
nm UV source light entering the reaction cell is absorbed by the
higher concentrations of SO2 typically measured by the 6400EH.

A window transparent to UV light provides an air-proof seal that
prevents ambient gas from contaminating the sample chamber.

9.1.2 Direct Measurement Interferences

The most common source of interference when measuring SO2 is
from other gases that fluoresce in a similar fashion to SO2 when exposed
to UV Light. The most significant of these are:

 A class of hydrocarbons called poly-nuclear aromatics (PNA) of

which xylene and naphthalene are two prominent examples.

 Nitric oxide (NO), which fluoresces in a spectral range near to SO

.

2

For critical applications where high levels of NO are expected an
optional 360 nm optical filter is available that improves the rejection
of NO (contact customer service for more information).

The methods by which the Model 6400EH rejects interference for
these substances differs from the M1 00E as follows.

 Since the typical application for which the 6400EH rarely includes

the presences of hydrocarbons or PNA’s, no hydrocarbon scrubber
(kicker) is included in the 6400EH’s base configuration. An
optional scrubber (see Section 5.4 of this manual is available).

Teledyne Analytical Instruments 38

UV Fluorescence SO2 Analyzer Theory of Operation

 On the other hand the typical 6400EH application often includes

much higher concentrations of Nitric Oxide (NO), which
fluoresces in a spectral range near that of SO

. Therefore a 360

2

nm filter replaces the 330nm UV filter located between the PMT
and the reaction cell in order to more efficiently reject for
interference due to the higher concentrations of NO.

9.2 Pneumatic Operation

9.2.1 Sample Gas Flow

The flow of gas through the 6400EH UV Fluorescence SO

2

Analyzer is created by a small external pump that pulls air through the
instrument. The 6400EH has no kicker to scrub hydrocarbons from the
sample stream. Typical applications for the 6400EH do not have
hydrocarbons in the sample stream.

Figure 9-2: Pneumatic Diagram of the6400EH – Base

Configuration

Teledyne Analytical Instruments 39

Theory of Operation Model 6400EH

9.2.2 Pneumatic Sensors

The 6400EH uses two pneumatic sensors to verify gas flow. These
sensors are located on a printed circuit assembly, called the pneumatic
pressure/flow sensor board. This PCA is attached to a manifold
containing the critical flow orifice that sets the instrument flow rate.

9.2.2.1 SAMPLE PRESSURE SENSOR

An absolute pressure transducer plumbed to the input of the
analyzer’s sample chamber is used to measure the pressure of the sample
gas before it passes through the critical flow orifice. This is used to
validate the critical flow condition (2:1 pressure ratio) through the
instrument’s critical flow orifice.

The actual sample gas pressure measurement is viewable through
the analyzer’s front panel display as the test function PRES.

9.2.2.2 VACUUM PRESSURE SENSOR

An absolute pressure transducer measures the pressure on the
vacuum side of the critical flow orifice and is used to measure the
sample gas pressure in the reaction cell. If the vacuum pressure is not in
the correct range, a warning will be displayed by the software. Also, if
the temperature/pressure compensation (TPC) feature is turned on, the
output of this sensor is also used to supply pressure data for that
calculation.

orifice (including the gas inside the reaction cell) viewable through the
analyzer’s front panel display as the test function

9.2.2.3 SAMPLE FLOW CALCULATION

VAC.

Unlike the 6400E, which uses a thermal-mass flow sensor to
directly measure the gas flow though the instrument, the 6400EH
calculates the gas as follows.

 The ratio of the two pressures is measured and used to validate

critical flow. If the ratio is not correct (< 2:1) the

If the pressure ratio between the two sensors is valid (≥ 2:1), the

If you suspect that one of the two pressure sensors is failing:

1. Cap the sample inlet.

2. After a few seconds, check the

VAC and PRES test functions and

verify that:

 The VAC value matches the PRES value to within 1 In-Hg-A,

and;

 Both are less than 10 in-Hg-A (i.e. under vacuum).

3. Uncap the sample inlet and unplug the pump.

4. After a few minutes, the value VAC and PRES should match

within 1 In-Hg-A, and read atmospheric pressure.

 If the two sensors do not match or are significantly different from

ambient atmospheric pressure, call Teledyne Analytical Instruments
customer service.

10.3 Repair Procedures

10.3.1 Repairing the Sample Gas Flow Control Assembly

The Critical Flow Orifice is part of the pressure sensor and flow
control assembly. The jewel orifice is protected by a sintered filter, so it
is unusual for the orifice to need replacing, but it is possible for the
sintered filter and o-rings to need replacing. See the Spare Parts list in
Appendix B for part numbers and kits.

To replace the filter and/or orifice

1. Turn off Power to the analyzer.

2. Locate the pressure sensor / flow control assembly.

3. Disconnect the signal cable and pneumatic fittings.

4. Remove the assembly from the optical bench by removing the 2

screws at each end of the assembly.

5. The inlet end of the assembly is located at the end with the

straight pneumatic fitting. Remove the fitting and the
components as shown in the exploded view.

6. Replace the o-rings (p/n:OR01) and the sintered filter (p/n:

FL01).

Teledyne Analytical Instruments 44

UV Fluorescence SO2 Analyzer Troubleshooting

7. if you are replacing the Critical Flow Orifice itself

(p/n:00094100), make sure that the side with the colored window
(usually RED) is facing upstream to the flow gas flow.

8. Re-assemble in reverse order. See the Spares List in Appendix B

for part numbers.

9. After re-connecting the power and pneumatic lines, flow check

the instrument as described in the Section 11.5.2 of the 6400E
Operator’s Manual.

Troubleshooting Model 6400EH

10.3.2 Sensor Module Repair & Cleaning

Note: After any repair or service has been performed on the

sensor module, the 6400EH should be allowed to warm up
for 60 minutes.

Always perform a leak check (See Section 11.5.1) and
calibrate the analyzer (see Chapter 7)
before placing it back in service.

The most significant difference between the 6400E sensor module
and the 6400EH sensor module is the location of the reference detector.
Therefore most of the procedures described in Section 11.6.3 apply to
the 6400EH as well.

10.3.2.1 ADJUSTING THE UV LAMP (PEAKING THE LAMP)

There are three ways in which ambient conditions can effect the
UV Lamp output and therefore the accuracy of the SO2 concentration
measurement. These are:

Line Voltage Change: UV lamp energy is directly proportional to the

line voltage. This can be avoided by installing adequate AC Line
conditioning equipment such as a UPS/surge suppressor.

Lamp Aging - Over a period of months, the UV energy will show a

downward trend, usually 30% in the first 90 days, and then a slower rate,
until the end of useful life of the lamp. Periodically running the UV
lamp calibration routine (see Section 6.9.7) will compensate for this
until the lamp output becomes too low to function at all.

Lamp Positioning – The UV output level of the lamp is not even across

the entire length of the lamp. Some portions of the lamp shine slightly
more brightly than others. At the factory the position of the UV lamp is
adjusted to optimize the amount of UV light shining through the UV
filter/lens and into the reaction cell. Changes to the physical alignment
of the lamp can affect the analyzers ability to accurately measure SO2.

CAUTION: ALWAYS WEAR UV-PROTECTIVE, SAFETY

GLASSES WHEN WORKING WITH THE UV LAMP
ASSEMBLY.

1. Set the analyzer display to show the signal I/O function,

UVLAMP_SIGNAL (see Section 11.1.3). UVLAMP_SIGNAL is

function 33.

2. Slightly loosen the large brass thumbscrew located on the shutter

housing (see Figure 10-3) so that the lamp can be moved.

3. While watching the UVLAMP_SIGNAL reading, slowly rotate the

lamp or move it back and forth vertically until the

UVLAMP_SIGNAL reading is at its maximum.

 DO NOT grasp the UV lamp by its cap when changing its

position (see Figure 10-3). Always grasp the main body of
the lamp.

4. Compare the UVLAMP_SIGNAL reading to the information in

Table 10-3 and follow the instructions there.

Table 10-3: Example of HVPS Power Supply Outputs

UVLAMP_SIGNAL ACTION TO BE TAKEN

3500mV±200mV. No Action Required

Adjust the UV reference detector potentiometer (see Figure 10-4) until

> 4900mV at any time.

>4500mV or < 1000mV

.< 600mV Replace the lamp.

UVLAMP_SIGNAL reads approximately 3600mV before continuing to adjust the lamp

position.

Adjust the UV reference detector potentiometer (see Figure 10-4) until

UVLAMP_SIGNAL reads as close to 3500mV as possible.

5. Finger tighten the thumbscrew.

Note: DO NOT over-tighten the thumbscrew.

10.3.2.2 PMT HARDWARE CALIBRATION (FACTORY CAL)

The sensor module hardware calibration adjusts the slope of the
PMT output when the instrument’s slope and offset values are outside of
the acceptable range and all other more obvious causes for this problem
have been eliminated.

Troubleshooting Model 6400EH

Figure 10-5: Pre-Amplifier Board Layout

1. Set the instrument reporting range type to SNGL (see Section

6.7.4 of the 6400E Manual)

2. Perform a zero–point calibration using zero air (see Chapter 7 of

the 6400E Manual).

3. Let the instrument stabilize by allowing it to run for one hour.

4. Adjust the UV Lamp. (See Section 10.3.2.1 of this manual)

5. Perform a LAMP CALIBRATION procedure (see Section 6.9.7 of

the 6400E Manual).

6. Locate the Preamp board (see Figure 3-4 of this manual).

7. Locate the Following Components On the Preamp board (see

Figure 10-5 of this manual):

HVPS coarse adjustment switch (Range 0-9, then A-F)



 HVPS fine adjustment switch (Range 0-9, then A-F)

 Gain adjustment potentiometer (Full scale is 10 to 12 turns).

8. Set the

Teledyne Analytical Instruments 50

HVPS coarse adjustment to its minimum setting (0).

UV Fluorescence SO2 Analyzer Troubleshooting

9. Set the HVPS fine adjustment switch to its maximum setting (F).

10. Turn the gain adjustment potentiometer clockwise to its

maximum setting.

11. Set the front panel display to show STABIL (see Section 6.2.1 of

the 6400E Manual)

12. Feed span gas into the analyzer.

13. Wait until the

STABIL value is below 0.5 ppm,

Note: Use a span gas equal to 80% of the reporting range.

Example: for a reporting range of 200 ppm, use a span gas
of 160 ppm.

14. Scroll to the OFFSET function and record the value.

15. Scroll to the NORM PMT value.

Note: Do not overload the PMT by accidentally setting both

adjustment switches to their maximum setting.
This can cause permanent damage to the PMT.

16. Determine the target NO RM PMT value according to the

following formulas.

 If the reporting range is set for ≤ 500 ppm (the instrument

will be using the 500 ppm physical range):

Target NORM PMT = (8 x span gas concentration) + OFFSET

 If the reporting range is set for ≥ 2,001 ppb (the instrument

will be using the 5,000 ppm physical range):

Target

NORM PMT = (0.8 x span gas concentration) + OFFSET

EXAMPLE

: If the OFFSET is 33 mV, the Reporting Range is

1000 ppm, the span gas should be 800 PPM SO2 and the
calculation would be:

Target

NORM PMT = (0.8 x 800) + 33 mV

Target NORM PMT = 640 + 33 mV

Target

NORM PMT = 673 mV

17. Set the HVPS coarse adjustment switch to the lowest setting that

will give you more than the target

NORM PMT signal from Step

16.

Teledyne Analytical Instruments 51

Troubleshooting Model 6400EH

18. The coarse adjustment typically increments the NORM PMT

signal in 100-300 mV steps.

19. Adjust the HVPS fine adjustment such that the NORM PMT value

is at or just above the target NORM PMT signal from Step 16.

20. Continue adjusting the both the coarse and fine switches until

NORM PMT is as close to (but not below) the target NORM PMT

value from Step 16.

21. Adjust gain adjustment potentiometer until the NORM PMT value

is ±10 mV of the target level from Step 16.

22. Perform span calibration (see Chapter 7 of the 6400E Manual)

23. Scroll to the SLOPE function and record the value.

24. If the value of the SLOPE is between 0.900 and 1.100 the PMT

Hardware calibration is complete.

25. If the value of the SLOPE is less than 0.900 or greater than 1.100:

a. Multiply the slope value from step 22 by the norm PMT

value from step 19.

b. Repeat steps 17 through 24 using this new value for NORM

PMT
