PREFACE  
(Addendum to M101E Manual - P/N 04740 Rev A)  
1. PREFACE  
NOTE  
The information contained in this addendum is pertinent to M102E analyzers running  
software revision A.2. Some or all of the information may not be applicable to previous  
revision of that software.  
The software revision your analyzer is running is displayed in the upper left-hand  
corner of the display any time the instrument is in SETUP mode.  
This addendum is based on the Model 101E Operators Manual (P/N 04740, REV. A). In most ways  
the M102E is identical to the M102E in design and operation, therefore most of the basic set up  
information, operating instructions as well as calibration, maintenance, troubleshooting and repair  
methods are found in that manual.  
This addendum documents only those areas where the M102E is different in design or operating  
method from the M102E.  
Specifically:  
Areas where updates and improvements to the M10XE software have been implemented  
since the publication date of the M101E Manual - P/N 04740 Rev A.  
Corrections of errors and omissions discovered in the M101E Manual - P/N 04740 Rev A.  
EXTERNAL TRS CONVERSION: Like the M101E, which converts H2S to SO2, then  
measures the amount of SO2 present using a UV fluorescence technique, the M102E  
converts total reduced sulfur (TRS) gases into SO2 before measuring the SO2 using the  
same UV fluorescence method.  
Unlike the M102E, which performs the H2S Æ SO2 conversion internally, the M102E  
requires an external TRS converter, in this case a Teledyne Instruments M501-TRS.  
Therefore this addendum includes instructions and information regarding:  
Areas of operation and setup of the M102 that depart from the method described by  
the M101E operator’s manual because the TRS Æ SO2 conversion is performed  
externally.  
The proper set up and operation on the M501-TRS.

GETTING STARTED  
(Addendum to M101E Manual - P/N 04740 Rev A)  
CAUTION  
The exhaust from the instrument needs to be vented outside the  
immediate area or shelter surrounding the instrument and conform to all  
safety requirements using a maximum of 10 meters of 1/4” PTFE tubing.  
9. Attach the sample line to the sample inlet port. Ideally, the pressure of the sample gas should  
be equal to ambient atmospheric pressure.  
NOTE  
Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-Hg above  
ambient pressure and ideally should equal ambient atmospheric pressure.  
In applications where the sample gas is received from a pressurized manifold, a vent  
must be provided to equalize the sample gas with ambient atmospheric pressure before  
it enters the analyzer. The vented gas needs to be routed outside the immediate area or  
shelter surrounding the instrument.  
10.Attach zero air and span gas supply lines as appropriate (see Figures 3-5 & 3.5).  
Zero air and span gas inlets should supply their respective gases in excess of the 700  
cc3/min demand of the analyzer. Supply and vent lines should be of sufficient length and  
diameter to prevent back diffusion and pressure effects.  
For this type of analyzer, zero air and span gas are defined as follows:  
SPAN GAS  
While it is possible to calibrate the M102E using SO2 as the span calibration gas by setting  
the analyzers gas measurement mode to SO2, Teledyne Instruments recommends that H2S  
be used and that calibration operations be carried out with the analyzer’s TRS gas  
measurement mode selected. Please note that verifying converter efficiency requires that  
the instrument be calibrated on both TRS and SO2, and the slope factors compared  
between the TRS and SO2 modes.  
It is recommended that the H2S span gas be equal to 90% of the analyzer’s selected  
reporting range.  
O2 is a quenching agent in fluorescent Sulfur analyzers. If the balance gas is pure  
nitrogen, then false positive readings will result, both at zero and span. Therefore the user  
should either use cylinders with zero air as the balance gas, or should use higher  
concentration cylinders with an N2 balance, and dilute further with zero air using a  
calibrator, such as the TAPI M700.  
EXAMPLE: If the selected reporting rang is 0 ppb Æ 500 ppb, an appropriate span gas  
concentration would be 450 ppb H2S.  
Cylinders of calibrated H2S gas traceable to NIST-Standard Reference Material specifications  
(also referred to as SRM’s or EPA protocol calibration gases) are commercially available. Table  
3-4 lists specific NIST-SRM reference numbers for various concentrations of H2S.

ZERO AIR  
A gas that is similar in chemical composition to the earth’s atmosphere but without the  
gas(es) being measured by the analyzer, in this case total reduced sulfur (TRS). While  
TRS typically includes Hydrogen sulfide (H2S), Dimethyl sulfide (CH3)2 , Dimethyl disulfide  
(CH3)2S2 and Methyl mercaptan (MeSH), CH4S many other gases fall into this category as  
well. In addition other interferent gases may be present in ambient air as well.  
To ensure that high quality zero air is available a zero air generator such as the Teledyne  
Instruments Model 701 should be used.  
If your analyzer is equipped with an IZS option, it is capable of creating zero air that is  
adequate for performing informal calibration checks, but a zero air generator such as the  
Teledyne Instruments Model 701 is still recommended for performing formal calibration  
operations.  
11.Once the appropriate pneumatic connections have been made, check all pneumatic fittings for  
leaks using a procedure similar to that defined in Section 11.5.1 of the M101E Manual - P/N  
04740 Rev A.  
3.6.2.1. Connections with Internal Valve Options Installed  
If your analyzer is equiped with either the zero/span valve option (Option 50) or the internal  
zero/span option (Option 51), the pneumatic connections should be made as shown in

NOTE  
Gas flow must be maintained at all times for units with IZS Options installed. The IZS  
option requires a permeation tube ( customer supplied ) which emits H2S. Insufficient  
gas flow can build up H2S to levels that will damage the instrument.  
Remove the permeation device when taking the analyzer out of operation.

3.7.3. Startup / Warm Up of the M501-TRS  
After electrical and pneumatic connections are made, turn on the instrument and pump power.  
The exhaust fan should start.  
The M501-TRS’ temperature controller is preprogrammed at the factory so no special setup  
operation is required. The temperature controller (see Figure 3-12) should immediately come on  
in operation mode: the current temperature of the converter oven should the display immediately  
appear in the display area and the process value (PV) LED should be lit.  
It may take as much as 30 minutes for the oven to reach its nominal operating temperature.  
During that initial warm up period the high and low alarms and the M501-TRS single alarm output  
are disabled. Both the internal alarms and the alarm output will be automatically enabled once  
the converter oven temperature rises above the lower alarm limit.

The output, labeled A3 is special. It can be set by the user (see Section 6.9.10 of the M101E  
Manual - P/N 04740 Rev A) to output many of the parameters accessible through the <TST TST>  
keys of the units Sample Display.  
Output A4 is not available on the Model 102E Analyzer.  
5.1.2. Setting the M102E Gas Measurement Mode  
Setting the gas measurement mode on the M102E is identical to the method described in Sections  
6.8.1 of the M101E Manual - P/N 04740 Rev A except that the available measurement ranges are:  
Table 5-1  
M102E gas Measurement Modes  
DESCRIPTION  
GAS  
MODE  
The sample gas stream is stripped of any ambient SO2 by a special  
chemical scrubber, then passed through a catalytic converter that  
changes the TRS present into SO2 which is then measured using the  
UV Fluorescence method  
TRS  
The sample gas stream bypasses the SO2 Scrubber and catalytic  
converter allowing the only ambient SO2 to be measured.  
SO2  
The switching valve alternates the gas stream between the two paths  
at regular intervals allowing the instrument to measure both gases.

INSTRUMENT MAINTENANCE  
M102E/M501 TRS  
(Addendum to M101E Manual - P/N 04740 Rev A)  
8.1. Additional and Updated Maintenance Procedures  
The following procedures need to be performed regularly as part of the standard maintenance of  
the Model 102E.  
8.1.1. Maintaining the SO2 Scrubber  
This section REPLACES Section 9.3.3 of the M101E Manual - P/N 04740 Rev A.  
Unlike the M101E which includes an internal scrubber to remove SO2 from the sample gas before  
the H2S Æ SO2 conversion takes place, the M102E relies on the SO2 scrubber of the M501-TRS to  
perform the same function.  
The SO2 scrubber of your M501-TRS utilizes a consumable compound to absorb SO2 from the  
sample gas before the TRS is converted to SO2. This material must be replaced periodically in  
order for the analyzer to continue measuring TRS accurately and reliability.  
This material is capable of efficiently scrubbing SO2 for up to 1000 ppm-hours. This means that if  
the SO2 content of the sample gas is typically around 100 ppb, the scrubber will function for  
approximately 10,000 hours, a little over 13 months. If, however, the typical ambient SO2 level  
of the sample gas is 250 ppb, the scrubber would only last for approximately 4000 hours or about  
5 ½ months.  
8.1.1.1. Predicting When the SO2 Scrubber Should Be Replaced.  
To determine how long the SO2 scrubber will operate efficiently:  
1. Measure the amount of SO2 in the sample gas.  
If your M102E has the multigas measurement options activated, this can be done by  
following instructions found in Section 6.8.1 of the M101E Manual (P/N 04740 Rev A) and  
selecting MEASURE MODE = SO2.  
Let the analyzer operate for 30 minutes, then note the SO2 concentration.  
2. Divide 1 000 by the SO2 concentration.  
EXAMPLE: If the SO2 concentration is 125 ppb:

(Addendum to M101E Manual - P/N 04740 Rev A)  
8.1.1.2. Checking the Function of the SO2 Scrubber  
To check to see if your SO2 scrubber is operating properly perform the following test:  
1. Set the analyzer for TRS gas measurement mode (see 6.8.1 of the M101E Manual - P/N 04740  
Rev A).  
2. Set the reporting range to range of 1000 PPB (see Sections 6.7.4; 6.7.5 & 6.7.6 of the M101E  
Manual - P/N 04740 Rev A).  
3. Introduce a gas mixture into the sample gas stream that includes 500 PPB of SO2.  
An increase of more than 10 PPB in the TRS reading is an indication that the efficiency of  
the scrubber is decreasing to the point that the absorbing material should be replaced.  
8.1.1.3. Changing the SO2 Scrubber Material  
1. Input zero air for 5 minutes  
2. Turn off the M501-TRS  
3. Locates the SO2 scrubber cartridge on the right side of the converter: It looks like a big  
white cylinder (See Figure 3-2 of this addendum).  
4. Undo the two 1/4 inch fittings on the top of the scrubber  
5. Remove the two screws holding the scrubber to the instrument chassis and remove the  
scrubber  
6. Take the two Teflon fittings off the instrument.  
7. Empty the SO2 scrubbing material into a hazmat bin  
8. Fill each side of the scrubber with new SO2 scrubber material until it is ½ inch from the  
bottom of the thread lines ( about 1 inch from the top of the scrubber ), do not fill it too high  
or the fitting will compact the material, causing a restriction in the gas flow.  
9. Remove the Teflon tape from both of the removed fittings, and wrap them with new Teflon  
tape.  
10. Install both fittings back onto the scrubber.  
11. Put the scrubber back into the analyzer and replace the two screws on the bottom.  
12. Screw the two 1/4” fittings back onto the top of the scrubber, they can be hooked up either  
way.  
13.Return analyzer to normal operation

M102E/M501 TRS  
THEORY OF OPERATION  
(Addendum to M101E Manual - P/N 04740 Rev A)  
9. THEORY OF OPERATION  
The M102E is a modified M101E which, when used in conjunction with a M501-TRS determines the  
concentration of total reduced sulfur (TRS), in a sample gas drawn through the instrument In  
most ways the theory of operation of the M102E & M501-TRS system is identical to the M101E  
theory of operation as described in Chapter 10 of the M101E Manual - P/N 04740 Rev A.  
This section describes those areas where differences between the M102E and the M101E exist as  
well as updated information made available since the publication date of the M101E Manual - P/N  
04740 Rev A.  
9.1. Measurement Principle  
This section supercedes Section 10.1 of the M101E Manual - P/N 04740 Rev A  
9.1.1. TRS Conversion  
The M102E TRS analyzer is basically an SO2 analyzer with a TRS Æ SO2 converter (the M501-  
TRS) inserted into the gas stream before the sample gas enters the sample chamber.  
The M501-TRS, receives sample gas from the M102E after it has been passed through a  
particulate filter and has been scrubbed of hydrocarbon interferents. Once inside the M501-TRS  
the sample gas is scrubbed of all naturally occurring SO2, then passed through a special quartz  
converter which heats the gas to a very high temperature causing it to react with the O2 present  
in the sample gas creating SO2 in the following manner .  
TRS + O2 Æ SO2  
(Equation 9-1)  
The converter is most efficient when it operates at 1000°C, converting >95% of the TRS into SO2.  
Converter temperature is viewable via the front panel of the M501-TRS  
When the converter is operating at peak efficiency there is a nearly 1:1 relationship between the  
amount of TRS entering the converter and the amount of SO2 leaving it. Therefore, by measuring  
the amount of SO2 in the gas after it leaves the converter, the amount of TRS originally present  
on the sample gas can be directly inferred.  
9.1.2. SO2 Ultraviolet Fluorescence  
The physical principle upon which the M102E’s measurement method is based is the fluorescence  
that occurs when sulfur dioxide (SO2) is excited by ultraviolet light with wavelengths in the range  
of 190 nm-230 nm. This reaction is a two-step process.  
The first stage (Equation 9-2) occurs when SO2 molecules are struck by photons of the  
appropriate ultraviolet wavelength. In the case of the Model 102E, a band pass filter between the  
source of the UV light and the affected gas limits the wavelength of the light to approximately 214

nm. The SO2 molecules absorbs some of energy from the UV light causing one of the electrons of  
each of the affected molecules to move to a higher energy orbital state.  
Ia  
SO2 + hv214nm SO2*  
(Equation 9-2)  
The amount of SO2 converted to excited SO2* in the sample chamber is dependent on the  
average intensity of the UV light (Ia) and not its peak intensity because the intensity of UV light  
is not constant in every part of the sample chamber. Some of the photons are absorbed by the  
SO2 as the light travels through the sample gas.

affected (path length).  
The second stage of this reaction occurs after the SO2 reaches its excited state (SO2*). Because  
the system will seek the lowest available stable energy state, the SO2* molecule quickly returns to  
its ground state (Equation 10-3) by giving off the excess energy in the form of a photon (hν). The  
wavelength of this fluoresced light is also in the ultraviolet band but at a longer (lower energy)  
wavelength centered at 330nm.

THEORY OF OPERATION  
(Addendum to M101E Manual - P/N 04740 Rev A)  
The amount of detectable UV given off by the decay of the SO2* is affected by the rate at which this  
reaction occurs (k).

(Equation9-6)  
Finally, the function (k) is affected by the temperature of the gas. The warmer the gas, the faster  
the individual molecules decay back into their ground state and the more photons of UV light are  
given off per unit of time.  
In summary, given that the absorption rate of SO2 (a) is constant, the amount of fluorescence (F)  
is a result of:  
The amount of exited SO2* created which is affected by the variable factors from equation  
10-2 above: concentration of SO2; intensity of UV light (I0); path length of the UV light (x)  
and;  
The amount of fluorescent light created which is affected by the variable factors from  
equation 10-5: the amount of SO2* present and the rate of decay (k) which changes based  
on the temperature of the gas.  
So, when the intensity of the light (I0) is known; path length of excited light is short (x).; the  
temperature of the gas is known and compensated for so that the rate of SO2*decay is constant(k).  
and; no interfering conditions are present (such as interfering gases or stray light); the amount of  
fluorescent light emitted (F) is directly related to the concentration of the SO2 in the Sample  
Chamber.  
The Model 100 E UV Fluorescence SO2 Analyzer is specifically designed to create these  
circumstances.  
The light path is very short (x).  
A reference detector measures the intensity of the available excitation UV light and is used  
to remove effects of lamp drift(I0).  
The temperature of the sample gas is measured and controlled via heaters attached to the  
sample chamber so that the rate of decay (k) is constant.  
A special hydrocarbon scrubber removes the most common interfering gases from the  
sample gas.  
And finally, the design of the sample chamber reduces the effects of stray light via its  
optical geometry and spectral filtering.  
The net result is that any variation in UV fluorescence can be directly attributed to changes in the  
concentration of SO2 in the sample gas.

9.2. The UV Light Path  
The following information is in addition to that contained in Section 10.2 of the M101E Manual -  
P/N 04740 Rev A.  
9.2.1. UV Lamp Shutter & PMT Offset  
Inherent in the operation of both the reference detector and the PMT are minor electronic offsets.  
The degree of offset differs from detector to detector and from PMT to PMT and can change over  
time as these components age.  
To account for these offsets the M102E includes a shutter, located between the UV Lamp and the  
source filter, that periodically cuts off the UV light from the sample chamber. This happens every  
30 minutes. The analyzer records the outputs of both the reference detector and the PMT during  
this dark period and factors them into the SO2 concentration calculation.  
The reference detector offset is stored as and viewable via the front panel as the test  
function DRK LMP.  
The PMT offset is stored as and viewable via the front panel as the test function DRK PMT  
9.3. Pneumatic Operation  
9.3.1. Sample gas Flow  
See Figures 3-4. 4-1 and 4-2 for depictions of the internal pneumatic flow of both the M102E &  
the M501-TRS.  
9.3.2. M501 SO2 Scrubber  
In order to ensure that no ambient SO2 interferes with the analyzer’s TRS measurement the  
sample gas stream is passed through a chemical scrubber that removes SO2 from the sample  
stream before it is passed though the M501-TRS converter oven.  
The SO2 scrubber is a Teflon encased, stand-alone unit containing a room-temperature catalyst  
tube mounted in the right side of the converter case (see Figure 3.2).  
The SO2 scrubber material is consumed as it removes SO2. If the expected concentrations of SO2  
are very high, the lifetime of the scrubber will be short. The expected life of the scrubber is  
approximately 1000 ppm-hours. See Section 8.1.1.3 for information on when and how to replace  
the SO2 scrubber material)

9.4.1. Sensor Module  
This Section replaces Section 10.4.2 of the M101E Manual - P/N 04740 Rev A.  
Electronically, the M102E sensor module is a group of components that: create the UV light that  
initiates the fluorescence reaction between SO2 and O3; sense the intensity of that fluorescence  
and generate various electronic signals needed by the analyzer to determine the SO2  
concentration of the sample gas (see Section 9.1) and sense and control key environmental  
conditions such as the temperature of the sample gas and the PMT.

9.4.1.2. Sample Chamber Heating Circuit  
In order to reduce temperature effects, the sample chamber is maintained at a constant 50°C,  
just above the high end of the instrument’s operation temperature range. Two AC heaters, one  
embedded into the top of the sample chamber, the other embedded directly below the reference  
detector’s light trap, provide the heat source. These heaters operate off of the instrument’s main  
AC power and are controlled by the CPU through a power relay on the relay board. A thermistor,  
also embedded in the bottom of the sample chamber, reports the cell’s temperature to the CPU  
through the thermistor interface circuitry of the motherboard.

THEORY OF OPERATION  
(Addendum to M101E Manual - P/N 04740 Rev A)  
9.4.2. M501-TRS electronics  
Electronically the M501-TRS is a simple device. The nucleus of the instrument is a programmable,  
P-I-D temperature controller which manages the temperature of the instruments’ AC powered  
converter oven based on analog input from K-type thermocouple attached to the converters  
chamber.

Figure 9-4:  
M501-TRS Electronic Block Diagram  
The P-I-D controller determines the differences between the actual temperature of the oven  
(called the process value or PV), compares it to the target temperature (called the set point or  
SV) and changes the percentage of time the heater is turned on versus the time it is turned off  
accordingly. The higher the proportion of ON-time versus OFF-time the faster the oven is heated.  
For instance, if the PV is much lower than the SV the P-I-D will keep the heater turned on 100%  
of the time resulting in a relatively rapid increase in the temperature of the oven. As the PV  
approaches the same temperature as the SV the ON cycles get shorter compared to the OFF  
cycles.  
The M501-TRS’s P-I-D controller includes sophisticated software that allows the controller to track  
the rate change in temperature of the oven compared to the percentage of heater ON-time and  
predict the proportion needed to reach and maintain the proper oven temperature with a minimal  
amount of overshoot or fluctuation.  
9.4.2.1. Thermal Switch  
While the M501-TRS’s P-I-D Controller includes many safeguards that prevent runaway heating of  
the converter oven, as an additional safety backup the M501-TRS includes a heat sensitive switch  
which automatically interrupts power to the heater if before the oven temperature reaches critical  
levels.

(Addendum to M101E Manual - P/N 04740 Rev A)  
9.4.2.2. Temperature Alarms and Alarm Output  
The M501-TRS’ controller has two user settable alarm points: High Alarm and Low Alarm. A single  
SPST alarm output is triggered should the PV rise above the set level of the high alarm point or  
fall below the level of the low alarm point.  
The relay is normally open, and the contact closes in the alarm condition. The relay contacts are  
isolated (dry) SPST, 220VAC / 30 VDC 1 Amp, resistive load. This alarm output is available via a  
connector on the rear panel of the M501-TRS.  
The M501-TRS temperature controller is programmed to hold off activation of either alarm until  
after the process value rises above the lower limit for the first time after power up.

TROUBLESHOOTING & REPAIR  
(Addendum to M101E Manual - P/N 04740 Rev A)  
10.2. M501-TRS Trouble shooting  
10.2.1. TRS Converter Not Heating:  
Problems with heating the If the TRS converter oven can have several causes.  
The “UUUU” error code will is displayed on the M501-TRS temperature controller display  
indicating a problem with the thermocouple  
Check the resistance across the thermocouple leads for opens or shorts.  
Check to make sure that the thermocouple leads are securely connected to the wiring  
block at the back of the controller.  
Make sure that the wiring block/socket is correctly plugged onto socket on the back pf  
the controller.  
The set point for the process value is set incorrectly.  
Check the set value; if it is incorrect, reset it.  
The controller is not in operational mode.  
Press the PV/SV switch to return it to operation mode.  
The heater is malfunctioning.  
CAUTION  
Make sure the M501-TRS is turned off and no AC power is being supplied  
to the heater before proceeding.  
Check the resistance across the heater coil. It should be approximately 16.5 ohms.  
Check the wiring between the heater and the power supply.  
Check to make sure the M501-TRS cooling fan is operating properly and that the  
instrument is properly ventilated. Poor ventilation can cause the M501-TRS’ thermal  
switch to turn off the converter to prevent overheating.  
Check to make sure that the thermal switch and heater control relay are operating  
properly.  
10.3. Other Performance Problems  
10.3.1. Excessive noise  
In addition to the causes listed in Section 11.4.1 of the M101E Manual (P/N 04740 Rev A), an  
excessively noisy TRS measurement can be caused by hysteresis or fluctuations in the  
temperature of the TRS converter oven in the M501-TRS. If this is the case, perform the autotune  
procedure described in Section 6.4. of this addendum.

10.4. Subsystem Checkout  
In addition to the information contained in Section 11.5 of the M101E Manual - P/N 04740 Rev A,  
the following diagnostic procedures are useful for troubleshooting and diagnosing problems with  
your M102E and M501-TRS.  
10.4.1. Checking the Efficiency of the M501-TRS SO2 Scrubber  
See Section 8.1.1.2 of this addendum  
10.4.2. Checking the Efficiency of the M501-TRS TRS Æ SO2  
Converter  
To check to see if your TRS Æ SO2 converter is operating properly:  
1. Set the analyzer to TRS measurement mode (see Section 6.8.1 of the M101E Manual - P/N  
04740 Rev A).  
2. Bypass the scrubber inside the M501-TRS.  
a. Unscrew the pneumatic fittings from the scrubber.  
b. Connect them with a stainless steel or Teflon® union.  
3. Supply a gas with a known concentration of SO2 to the sample gas inlet of the analyzer.  
4. Wait until the analyzer’s output concentration measurement stabilizes. This can be  
determined by setting the analyzer’s display to show the TRS STB test function (see Section  
6.2.1 of the M101E Manual - P/N 04740 Rev A) TRS STB should be 0.5 ppb or less before  
proceeding.  
5. Record the stable SO2 concentration (Although the concentration is labeled TRS, we are  
measuring SO2)  
6. Supply a gas with a concentration of H2S equal to that of the SO2 gas used in steps 2 through  
5 above, to the sample gas inlet of the analyzer.  
7. Wait until the analyzer’s output concentration measurement stabilizes. This can be  
determined by setting the analyzer’s display to show the TRS STB test function (see Section  
6.2.1) TRS STB should be 0.5 ppb or less before proceeding.  
8. Record the stable TRS concentration  
9. Divide the TRS concentration by the SO2 concentration

TROUBLESHOOTING & REPAIR  
(Addendum to M101E Manual - P/N 04740 Rev A)  
10.If TRS Æ SO2 converter efficiency is below 90% check for one of the following possible causes:  
Pneumatic leak  
Perform a leak check (with the M501-TRS connected) as described in Section 11.5.1 of  
the M101E Manual - P/N 04740 Rev A.  
Plugged or constricted pneumatic flow?  
Perform a sample flow check as described in Section 11.5.2 of the M101E Manual - P/N  
04740 Rev A. This tests the entire system  
Disconnect the gas feed line from the FROM ANALYZER port of the M501-TRS.  
Attach the flow meter to the port and repeat the test. Isolates the portions of the  
pneumatic system down stream from the TRS Æ SO2 switching valve but includes the  
M501-TRS in the flow test.  
Attach the flow meter to the FROM CONVERTER port at the back of the M102E.  
Retest. This bypasses M501-TRS during the flow test.  
Improper Set point temperature. Call Teledyne API’s customer service for advice.  
Span Gas used in efficiency test was incorrect/wrong concentration. Independently verify  
the concentration of the span gas.  
Contaminants in the converter chamber, pneumatic lines. Sometimes contaminants such  
as tiny particles of scrubber material from the M501-TRS’ SO2 scrubber can get into the  
converter tube and react with the TRS Æ SO2 conversion process, if the inline filter after  
the scrubber was damaged..  
Call Teledyne Instruments customer service for instructions on cleaning the converter tube and  
M501-TRS pneumatic lines.  
10.5. Additional Repair Procedures  
The following repair procedures are in addition to those listed in Section 11.6 of the M101E  
Manual - P/N 04740 Rev A,  
10.5.1. UV Lamp Adjustment and/or Replacement  
There are three ways in which ambient conditions can affect the UV Lamp output and therefore the  
accuracy of the TRS 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%  
- 50% 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 of the M101E Manual - P/N  
04740 Rev A) will compensate for this until the lamp output becomes too low to function at all, 2-  
3 years nominally.

(Addendum to M101E Manual - P/N 04740 Rev A)  
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  
analyzer’s ability to accurately measure SO2. See Section 11.6.3.2 of the M101E Manual (P/N  
04740 Rev A) for instructions on adjusting the lamp position.  
10.5.1.1. Adjusting the UV Lamp (Peaking the Lamp)  
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 of the M101E Manual - P/N 04740 Rev A). UVLAMP_SIGNAL is function 35.  
2. Slightly loosen the large brass thumbscrew located on the shutter housing (see Figure 10-1)  
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.  
NOTE:  
DO NOT grasp the UV lamp by its cap when changing its position (see Figure 10-1).  
Always grasp the main body of the lamp.  
Ideally, the reading should be 3500mV±200mV.  
If UVLAMP_SIGNAL is lower than 600mV, replace the lamp.  
If UVLAMP_SIGNAL is greater than 3800 mV, adjust the pot on the UV reference board  
down until the output reads 3500 mV, and then continue to peak the lamp.  
4. Finger tighten the thumbscrew.  
NOTE:  
DO NOT over-tighten the thumbscrew.

The thermo-electric cooler needs to be mounted flat to the heat sink. If there is any  
significant gap, the TEC might burn out. Make sure to apply heat sink paste before  
mounting it and tighten the screws evenly and cross-wise.  
a. Make sure to use thermal grease between the TEC and the cooling fins as well as between  
the TEC and the cold block.  
b. Align the side opening in the cold block with the hole in the PMT housing where the sample  
Chamber attaches.  
c. Evenly tighten the long mounting screws for good thermal conductivity.  
13.Re-insert the TEC subassembly. Make sure that the O-ring is placed properly and the assembly  
is tightened evenly.  
14.Insert the LED and thermistor into the cold bloc.

15.Re-insert the PMT/HVPS subassembly.  
Don’t forget the gasket between HVPS and PMT.  
Use new plastic screws to mount the PMT assembly on the PMT cold block.  
16.Insert the new desiccant bags.  
17.Carefully replace the end plate.  
Make sure that the O-ring is properly in place. Improperly placed O-rings will cause leaks,  
which – in turn – cause moisture to condense on the inside of the cooler causing the HVPS  
to short out.  
18.Reconnect the cables and the reaction cell  
Be sure to tighten these screws evenly,  
19.Replace the sensor assembly into the chassis and fasten with four screws and washers.  
20.Reconnect all electrical and pneumatic connections, leak check the system and power up the  
analyzer. Verify the basic operation of the analyzer using the ETEST and OTEST features (see  
Section 6.9.5 & 6.9.6 of the M101E Manual - P/N 04740 Rev A) or by measuring calibrated  
zero and span gases.  
21.Perform a PMT Hardware calibration (see Section 11.6.6 of the M101E Manual - P/N 04740 Rev  
A)  
22.Perform a zero point and span calibration (See Chapter 7 of the M101E Manual - P/N 04740  
Rev A)  
10.5.4. M102E PMT Hardware Calibration (FACTORY CAL)  
This procedure supercedes the one contained in section 11.6.3 of the M101E Manual -  
P/N 04740 Rev A.  
The sensor module hardware calibration adjusts the slope of the PMT output when the  
Instruments slope and offset values are outside of the acceptable range and all other more  
obvious causes for this problem have been eliminated.  
1. Set the instrument reporting range to SNGL & 500 ppb (see Section 6.7.4 of the M101E  
Manual - P/N 04740 Rev A)  
2. Perform a full zero–point calibration using zero air (see Chapter 7 of the M101E Manual - P/N  
04740 Rev A).  
3. Let the instrument stabilize by allowing it to run for one hour.  
4. Adjust the UV Lamp. (See Section 10.5.1.1 of this addendum)  
5. Perform a LAMP CALIBRATION procedure (see Section 6.9.7 of the M101E Manual - P/N  
04740 Rev A).

(Addendum to M101E Manual - P/N 04740 Rev A)  
If a reporting range other than 500 ppb is used in this procedure:  
Use a span gas equal to 80% of the reporting range and adjust the PMT to a target  
NORM PMT value of twice the ppb value of the span gas.  
EXAMPLE  
If the reporting range is 800 ppb:  
Use 640 ppb span gas.  
Adjust the PMT until NORM PMT equals 1280 mV ± 10 mV  
13.Wait until the STABIL value is below 0.5 ppb,  
14.Scroll to the NORM PMT value.  
15.Set the HVPS coarse adjustment switch to the lowest setting that will give you more than 1000  
mV NORM PMT signal.  
The coarse adjustment typically increments the NORM PMT signal in 100-300 mV steps.  
16.Adjust the HVPS fine adjustment such that the NORM PMT value is at or just above 800 mV.  
NOTE  
Do not overload the PMT by setting both adjustment switches to their maximum setting.  
This can cause permanent damage to the PMT.  
17.Continue adjusting the both the coarse and fine switches until NORM PMT is as close to 800  
mV as possible.  
18.Adjust the gain adjustment potentiometer until the NORM PMT value is 800 mV ±10 mV.  
19.Perform span and zero-point calibrations (see Chapter 7 of the M101E Manual - P/N 04740 Rev  
A) to normalize the sensor response to its new PMT sensitivity.  
20.Review the slope and offset values, and compare them to the values in Table 7-5 of the M101E  
Manual - P/N 04740 Rev A.

2. Allow it to cool to room temperature. This may take up to 30 minutes.  
3. Remove the instruments top cover (see Section 3.2 of this addendum)  
4. Remove the four screws holding the converter cover in place.  
5. Carefully lift the converter cover away.  
6. Loosen front and rear pneumatic fittings at each end of the tube and remove the gas lines  
from the converter tube.  
7. Remove the front ceramic bobbin from the converter tube. The thermistor assembly will come  
with it.  
NOTE:  
Be Careful!  
The ceramic bobbins at each end of the heater assembly are fragile.  
8. Slide a new tube into the heater coil assembly.  
9. Make sure that the thermistor is threaded through its notch on the center hole of the front  
converter bobbin and properly seated in the corresponding indentation in the body of the  
quartz heater tube.  
10.Reattach the front bobbin onto the converter tube.  
11.Reattach the gas lines and retighten the pneumatic fittings.  
12.Reassemble the converter cover and reattach the M501-TRS top cover.  
NOTE  
The M501-TRS will not operate properly with the top cover removed.  
The air cooling required to stabilize the temperature of the converter tube is dependent  
on air flow patterns that only exist with the top cover in place.  
Without the top cover in place, the thermal cutout may overheat, and shut the heating  
element off.  
13.Restart the M501-TRS.  
14.Check the converter efficiency. See Section 10.4.2 of this addendum.  
10.6. Manually Programming the M501-TRS  
Temperature Controller

DO NOT manually alter the PID parameters of the M501-TRS temperature Controller  
unless directed to do so by Teledyne Instruments customer service personnel.  
In the event that the temperature controller of the M501-TRS must be replaced some initial  
programming is required set the control functions if reprogramming is necessary. The following  
tables define the approximate initial values for various processes control parameters. Once they  
are set, perform an autotune procedure as defined in Section 6.4 of this addendum  
10.6.1. Temperature Controller Primary Menu Parameters  
NOTE  
Tables 10-3 and 10-4 show the typical primary P-I-D parameter values for operation on  
115V/60Hz with a set value of 1000°C.  
The P, I and d values may be different for other AC main voltages (call Teledyne  
Instruments customer service, and will vary somewhat after auto-tuning.  
To set these parameters:  
1. Open the appropriate menu  
a. Press the SELECT key once to access the primary menu parameters. The main display will  
show  
.
b. Press and Hold the SELECT key for 3 seconds to access the primary menu parameters. The  
main display will show  
.
2. Use the SELECT , DOWN or 100’s UP key to scroll through the primary menu parameters until  
the appropriate parameter is displayed (see Table 10-3 or Table 10-4).  
3. Press the DATA key once. The current value of the parameter will be displayed.  
4. To set each digit:  
a. Press the up-arrow under that digit once. The digit will flash.  
b. To increment that digit, press and hold the digit until the appropriate number is displayed.  
c. To decrement that digit press and hold the DOWN key until the appropriate number is  
displayed.  
d. To increment/decrement the 1000’s digit it is necessary to adjust increment/decrement the  
100’s digit up and down. Each time the 100’s digit passes “0” the 1000s digit will  
increment or decrement correspondingly.  
5. Once the desired value is reached, press the ENT key to store the new set Parameter value.  
6. Press the PV/SV mode key to return to operational mode.
