INTRODUCTION
1. Introduction
1.1 Overview
This manual describes the Rosemount Analytical Micro Continuous Emission Monitoring (µCEM) gas Analyzer Module.
The µCEM Analyzer Module is designed to continuously determine the concentration of O2, CO,
CO2, SO2, and NOx in a flowing gaseous mixture. The concentration is expressed in percent or partsper-million.
The sampled gas is collected from the stack and prepared by the Probe/Sample Handling Enclosure for analysis and processing by the Analysis Enclosure. The ANALYSIS ENCLOSURE is a stand alone, computer-controlled unit, utilizing PC/104 as the system bus. The uCEM is enclosed in rugged NEMA
4X, IP65 type enclosures, for harsh environment. The ANALYSIS ENCLOSURE utilizes convection cooling with no air intake and air vents. The ANALYSIS ENCLOSURE is modular, general purpose and easily expandable. It utilizes industry standard components such as PC/104 boards, and modular signal conditioning modules.

INTRODUCTION
1.3 Theory of Operation
1.3.1 NOx
The NOx analyzer continuously analyzes a flowing gas sample for NOx [nitric oxide (NO) plus nitrogen dioxide (NO
2
)]. The sum of the concentrations is continuously reported as NOx.
The µCEM NOx Analyzer Module uses the chemiluminecence method of detection. This technology is based on NO’s reaction with ozone (O
3
) to produce NO
2
and oxygen (O
2
). Some of the NO
2
molecules produced are in an electronically excited state (NO
2
* where the * refers to the excitation). These revert to the ground state, with emission of photons (essentially, red light). The reactions involved are:
NO
NO
2
2
+ O
3
→ NO
*
→ NO
2
* + O
2
2
+ red light
The sample is continuously passed through a heated bed of vitreous carbon, in which NO
2
is reduced to NO.
Any NO initially present in the sample passes through the converter unchanged, and any NO
2
is converted to an approximately equivalent (95%) amount of NO.
The NO is quantitatively converted to NO
2
by gas-phase oxidation with molecular ozone produced within the analyzer from air supplied by an external source. During the reaction, approximately 10% of the NO
2
molecules are elevated to an electronically excited state, followed by immediate decay to the non-excited state, accompanied by emission of photons. These photons are detected by a photomultiplier tube which produces an output proportional to the concentration of NOx in the sample.
To minimize system response time, an internal sample bypass feature provides high-velocity sample flow through the analyzer.
1.3.2 CO
The optical bench can selectively measure multiple components in a compact design by using a unique dual optical bench design. Depending on the application, any two combinations of NDIR channels can be combined on a single chopper motor/dual source assembly.
Other application-dependent options include a wide range of sample cell materials, optical filters and solid state detectors. The NDIR Microflow detector consists of two chambers, measurement and reference with an interconnected path in which an ultra low flow filament sensor is mounted. During operation, a pulsating flow occurs between the two chambers which is dependent upon: sample gas absorption, modulation by the chopper motor and the fill gas of the detector chambers. The gas flow/sensor output is proportional to the measured gas concentration. The optical bench is further enhanced by a novel “Look-through” detector technique. This design allows two detectors to be arranged in series --- enabling two different components to be measured on a single optical bench. The optical bench contains a unique eddy current drive chopper motor and source assembly. This design incorporates on board “intelligence” to provide continuous “self test” diagnostics.
1.3.3 O2
Paramagnetic: The determination of oxygen is based on the measurement of the magnetic susceptibility of the sample gas. Oxygen is strongly paramagnetic, while other common gases are not. The detector used is compact, has fast response and a wide dynamic range. The long life cell is corrosion resistant, heated and may be easily cleaned. It has rugged self-tensioning suspension and is of welded Non-Glued construction.

2. Detector Methodologies
The µCEM can employ up to three different measuring methods depending on the configuration chosen. The methods are: NDIR CO/CO2/SO2, Paramagnetic O
2
, Electrochemical O
2
, and chemiluminescent NOx.
2.1 Non-Dispersive Infrared (NDIR)
The non-dispersive infrared method is based on the principle of absorption of infrared radiation by the sample gas being measured. The gas-specific wavelengths of the absorption bands characterize the type of gas while the strength of the absorption gives a measure of the concentration of the gas component being measured.
An optical bench is employed comprising an infrared light source, two analysis cells (reference and measurement), a chopper wheel to alternate the radiation intensity between the reference and measurement side, and a photometer detector. The detector signal thus alternates between concentration dependent and concentration independent values. The difference between the two is a reliable measure of the concentration of the absorbing gas component.
Depending on the gas being measured and its concentration, one of two different measuring methods may be used as follows:
2.1.1 Interference Filter Correlation Method
With the IFC method the analysis cell is alternately illuminated with filtered infrared concentrated in one of two spectrally separated wavelength ranges. One of these two wavelength bands is chosen to coincide with an absorption band of the sample gas and the other is chosen such that none of the gas constituents expected to be encountered in practice absorbs anywhere within the band.
The spectral transmittance curves of the interference filters used in the µCEM analyzer and the spectral absorption of the gases CO and CO
2
are shown in Figure 2.1 below. It can be seen that the absorption bands of these gases each coincide with the passbands of one of the interference filters. The fourth interference filter, used for generating a reference signal, has its passband in a spectral region where none of these gases absorb.
Most of the other gases of interest also do not absorb within the passband of this reference filter.
The signal generation is accomplished with a pyroelectrical (solid-state) detector. The detector records the incoming infrared radiation. This radiation is reduced by the absorption of the gas at the corresponding wavelengths. By comparing the measurement and reference wavelength, an alternating voltage signal is produced. This signal results from the cooling and heating of the pyroelectric detector material.

Figure 2-1. Absorption Bands of Sample Gas and Transmittance of Interference Filters
2.1.2 Opto-Pneumatic Method
In the opto-pneumatic method, a thermal radiator generates the infrared radiation which passes through the chopper wheel. This radiation alternately passes through the filter cell and reaches the measuring and reference side of the analysis cell with equal intensity. After passing another filter cell, the radiation reaches the pneumatic detector.
The pneumatic detector compares and evaluates the radiation from the measuring and reference sides of the analysis cell and converts them into voltage signals proportional to their respective intensity.
The pneumatic detector consists of a gas-filled absorption chamber and a compensation chamber which are connected by a flow channel in which a Microflow filament sensor is mounted. This is shown in Figure 2-2 below.
In principle the detector is filled with the infrared active gas to be measured and is only sensitive to this distinct gas with its characteristic absorption spectrum. The absorption chamber is sealed with a window which is transparent for infrared radiation. The window is usually Calcium Fluoride (CaF
2
).
When the infrared radiation passes through the reference side of the analysis cell into the detector, no preabsorption occurs. Thus, the gas inside the absorption chamber is heated, expands and some of it passes through the flow channel into the compensation chamber.

Figure 2-2. Opto-Pneumatic Gas Detector
When the infrared radiation passes through the open measurement side of the analysis cell into the detector, a part of it is absorbed depending on the gas concentration. The gas in the absorption chamber is, therefore, heated less than in the case of radiation coming from the reference side. Absorption chamber gas becomes cooler, gas pressure in the absorption chamber is reduced and some gas from the compensation chamber passes through the flow channel into the absorption chamber.
The flow channel geometry is designed in such a way that it hardly impedes the gas flow by restriction. Due to the rotation of the chopper wheel, the different radiation intensities lead to periodically repeated flow pulses within the detector.
The Microflow sensor evaluates these flow pulses and converts them into electrical pulses which are processed into the corresponding analyzer output.
DETECTOR METHODOLOGIES
2.1.3 Overall NDIR Method
In the case of dual-channel analyzers, the broadband emission from two infrared sources pass through the chopper wheel. In the case of the Interference Filter Correlation (IFC) method, the infrared radiation then passes through combinations of interference filters. In the case of the opto-pneumatic method, the infrared radiation passes through an optical filter depending on the application and need for reduction of influences.
Then the infrared radiation enters the analysis cells from which it is focused by filter cells onto the corresponding detector. The preamplifier detector output signal is then converted into the analytical results expressed directly in the appropriate physical concentration units such as percent volume, ppm, mg/Nm
3
, etc.
This is shown in
Figure 2-3 below.

2.2 Paramagnetic Oxygen Method
The paramagnetic principle refers to the induction of a weak magnetic field, parallel and proportional to the intensity of a stronger magnetizing field.
The paramagnetic method of determination of oxygen concentration utilizes nitrogen filled quartz spheres arranged at opposite ends of a bar, the center of which is suspended by and free to rotate on a thin platinum wire ribbon in a cell. Nitrogen (N2) is used because it is diamagnetic or repelled by a magnet.
A small mirror that reflects a light beam coming from a light source to a photodetector, is mounted on the platinum ribbon. A strong permanent magnet specifically shaped to produce a strong, highly inhomogeneous magnetic field inside the analysis cell, is mounted outside the wall of the cell.
When oxygen molecules enter the cell, their paramagnetism will cause them to be drawn towards the region of greatest magnetic field strength. The oxygen molecules thus exert different forces on the two suspended nitrogen filled quartz spheres, producing a torque which causes the mirror to rotate away from its equilibrium position.
The rotated mirror deflects the incident light onto the photodetector creating an electrical signal which is amplified and fed back to a coil attached to the bar holding the quartz spheres, forcing the suspended spheres back to the equilibrium position.
The current required to generate the restoring torque to return the quartz bar to its equilibrium position is a direct measure of the O
2
concentration in the sample gas.
The complete paramagnetic analysis cell consists of an analysis chamber, permanent magnet, processing electronics, and a temperature sensor. The temperature sensor is used to control a heat exchanger to warm the measuring gas to about 55
°C.
DETECTOR METHODOLOGIES
2.3 Electrochemical Oxygen Method
The electrochemical method of determining oxygen concentration is based on the galvanic cell principle shown in Figure 24 below.
Figure 2-4. Electrochemical Oxygen Sensor
The electrochemical oxygen sensor incorporates a lead and gold galvanic process with a lead anode (1) and a gold cathode (2), using an acid electrolyte (3).
Oxygen molecules diffuse through a non-porous Teflon membrane (4) into the electrochemical cell and are reduced at the gold cathode. Water is the byproduct of this reaction.
On the anode, lead oxide is formed which is transferred into the electrolyte. The lead anode is continuously regenerated and, therefore, the electrode potential remains unchanged for a long time. The rate of diffusion and corresponding response time (t
90
) of the sensor is dependent on the thickness of the Teflon membrane.
The electric current between the electrodes is proportional to the O
2
concentration in the sample gas being measured. The resultant signal is measured as a voltage across the resistor (6) and thermistor (5), the latter of which is used for temperature compensation. A change in the output voltage (mV) represents oxygen concentration.
NOTE: The electrochemical O
2
cell requires a minimum internal consumption of oxygen. Sample gases with an oxygen concentration of less than 2% could result in a reversible detuning of sensitivity and the output will become unstable. The recommended practice is to purge the cell with conditioned ambient air between periods of measurement. If the oxygen concentration is below 2% for several hours or days, the cell must be regenerated for about one day with ambient air. Temporary flushing with nitrogen (N
2
) for less than one hour
(analyzer zeroing) will have no effect on the sensitivity or stability.

Analysis Enclosure Critical settings and control:
1. Set MicroCEM Pressure guage (P1) to 5 psig +/- 0.5psig. Pressure set by BPR located behind gauge in detector section. For Stream Switch systems both streams will need to be set to 5 psig. Use trim valve in stream switch box to attain proper pressures. If CO and NOx response times are sluggish this pressure can be increased. Note: Customer must assure that no backpressure exists on the exhaust vent. Exhaust vent must be minimum 3/8” and no more than 10’ in length. If greater then 10' in length, then ½” should be used.
2. Set Flowmeter (F1) to 500cc to 1500cc per min.
3. TV1 is used to balance the flow between a probe and local calibration. It is located beside the solenoid valve manifold.
4. Set Ozone air pressure to 12 psig. Customer pressure regulator must be used.
5. Exhaust line should be free of any backpressure. Immediately vent into ½” pipe.
6. Time Share Box:
TV1: Use to equalize cal gas flow between SHU1 and SHU2.
TV2: Use to equalize cal gas flow between SHU1 and SHU2.
TV3: Use to equalize sample flow between SHU1 and SHU2.
TV4: Use to equalize sample flow between SHU1 and SHU2.
7. Pressure Switch: The pressure switch is located beside the pressure gauge. If the sample or cal gas pressure flow below 2.5 psig the MicroCEM will give trouble alarm. The alarm will turn off upon pressure above 4 psig. This alarm will also trigger and Invalidation status. (Time Share or extended I/O is required for this function.

Procedure for setting calibration gas pressures on the MicroCEMS.
1. Add a 0-(20-30) psi gauge at the SAMPLE INLET to the analyzer box.
2. Set the sample bypass check valve (across the outlet/inlet of the sample pump) for a pressure of 12-14 psig at the SAMPLE INLET to the analyzer box.
3. Set all calibration gas regulators so that WITH CALIBRATION GAS FLOWING, the pressure at the
SAMPLE INLET to the analyzer box is 2-3 psig higher than the previously set pressure of the pump only. This will typically result in a regulator gauge pressure of 3-5 psig (depending on the distance from the bottles to the analyzer box plus the distance from the analyzer box to the probe box).
This method assures positive pressure to the pump so that the pump is never pulling a vacuum on the bottles. It also assures that the pump diaphragm will never be damaged by excessive pressure from the bottles.
3.2 Process and Calibration Gas Connection
Besides sample gas, the µCEM requires other gases for operation. In most cases, one or more Calibration
Standards must be provided. These should be cylinders of gas which closely resemble the expected sample, both in species and concentrations. These calibration gases are normally introduced into the system as an input to the Sample Conditioning Plate Option or sample conditioning may be provided by others.
Each gas cylinder should be equipped with a clean, hydrocarbon free two-stage regulator with indicating gauges of approximately 0 to 3000 psig (0 to 20.7 Mpa) for cylinder pressure and 0 to 100 psig (0 to 689 Kpa) for delivery pressure. Regulators should have a metallic as opposed to elastomeric diaphragm, and provide for ¼ inch compression fitting outlet and should be LOX clean.
NOTE: All connections specified in the Installation Drawing, in conjunction with the Application Data
Sheet, should be made.

3.2.1 Gas Conditioning
All gases must be supplied to the analyzer as conditioned gases! When the system is used with corrosive gases, it must be verified that there are no gas components which may damage the gas path components.
The gas conditioning must meet the following conditions:
Free of condensable constituents
Free of dust above 2
µm
Free of aggressive constituents which may damage the gas paths
Temperature and pressure in accordance with the specifications
When analyzing vapors, the dewpoint of the sample gas must be at least 10
°C below the ambient temperature in order to avoid the precipitation of condensate in the gas paths.
An optional barometric pressure compensation feature can be supplied for the µCEM. This requires a pressure sensor with a range of 800 – 1,100 hPa. The concentration values computed by the detectors will then be corrected to eliminate erroneous measurements due to changes in barometric pressure.
The gas flow rate must be in the range of 0.5 l/min to a maximum of 1.5 l/min. A constant flow rate of 1 l/min is recommended. NOTE: The maximum gas flow rate for paramagnetic oxygen detectors is 1.0 l/min!

3.3 Installation
WARNING: ELECTRICAL SHOCK HAZARD
Care should be taken if hazardous gases are to be measured or used for calibration.
Refer to installation drawing supplied with the application data package.
3.3.1 Location
The µCEM is designed to be installed in an outdoor environmental location but, the analyzer must be located out of direct sunlight and direct rain/snow to the extent possible to assure that the environmental and temperature specifications are met. If the unit is exposed to direct sunlight then internal components damage may occur along with the possibility of inaccurate gas measurements. This will void the warranty, Typically an inexpensive overhang sun shield or lean-to is adequate to assure the blocking of direct sunlight.
The µCEM analysis enclosure should be installed as near as possible to the probe/sample handling enclosure, in order to avoid low response time caused by long sample gas lines.
The enclosure must be grounded to earth by the user or ground loops and computer lockups are possible.
3.3.2 Limitations
Ambient Temperature: -30
° to 50° Celsius (-34° to 122° F)
Relative Humidity: 5% to 99%
3.3.3 Mounting Options
Although the µCEM is enclosed in an environmentally sealed enclosure, it must be protected from direct sunlight. In areas subjected to harsh winter climates, protection should also be provided from sun, rain and snow. A corrugated awning, lean-to or other suitable means can be provided to meet these conditions.
3.3.4 Electrical Connections
NOTE: The enclosure is a NEMA 4x. All entry locations must be sealed.
Connect all required signal cables to the connections at the bottom of the µCEM. The cable locations are indicated on the inside bottom cover of the µCEM box. The actual electrical connections will be specified in the

3.3.6 Analytical Leak Check
If explosive or hazardous gas samples are being measured with the µCEM, it is recommended that gas line fittings and components be thoroughly leak-checked prior to initial application of electrical power, and at bimonthly intervals thereafter, as well as after any maintenance which involves breaking the integrity of the sample containment system.

Rosemount Analytical µCEM Continuous Analyzer Transmitter 3–26
INSTALLATION
3.3.6.1 Flow Indicator Method
Supply air or inert gas such as nitrogen, at 10 psig (689 hPa), to the analyzer through a flow indicator with a range of 0 to 250 cc/min. Install a shut-off valve at the sample gas outlet. Set the flow rate to 125 cc/min.

INSTALLATION
3.3.5.3 Troubleshooting Leaks
Liberally cover all fittings, seals, and other possible sources of leakage with a suitable leak test liquid such as
SNOOP
™
(part 837801). Bubbling or foaming indicates leakage. Checking for bubbles will locate most leaks but could miss some, as some areas are inaccessible to the application of SNOOP. For positive assurance that system is leak free, perform one of the preceding tests.
NOTE:
Refer to Specification in Preface for maximum pressure limitations.
For differential measurement, the leak check must be performed for the measurement and reference side separately.
For analyzers with parallel gas paths, the leak check must be performed for each gas path separately.

4.1 Startup Procedure
Once the µCEM has been correctly assembled and installed in accordance with the instructions in Section 3, the analyzer is ready for operation.
Before operating the system, verify that the Leak Checks have been performed and that the sample handling unit is performing correctly.
MicroCEM analysis enclosure On/Off switch is located inside the door on the bottom right hand corner. Push switch to the “on” position to start system.
The unit will immediately run thru a self diagnostic mode. This may take up to 2 minutes. The user will know the system has passed all diagnostic test and is “ready” upon the green LED (located above on/off switch) is flashing. If the green LED does not start to flash verify that proper power is connected to the unit and restart. If
AC/Heater fan is running but the green LED still will not flash then call the factory immediately for help.
NOTE: After startup a warm-up time from 20 to 60 minutes (Depending upon ambient temp) is required for accurate measuements.
Analyzer operation can be confirmed by the green LED light flashing. The pocket pc can then be connected for viewing menus. Upon power up, the analyzer will perform a self-test routine. The test will take approximately 6 minutes.

4.2.7 Time Share Switching Control Option
Typically a Time Share system is in Automatic Stream Switching mode. That means that it runs the timing schedule specified in User Settings Configuration file. If Automatic switching is not desirable, the user may turn it off using Tools-> Stop Auto Switching menu. In this case the system will remain on the current stream indefinitely. When Automatic switching is needed again, user may turn it back on with Tools->Start Auto
Switching menu.
The same task can be accomplished remotely, by clicking Stop Auto Switching button on the µCEM Real-Time
Web page.
Note, that this option is sustained even if the system is rebooted.
The operator may also force a switch between the streams at any time whether the system is in Auto-Switching mode or not. Tools menu has an option “Switch to StreamName”, where StreamName is a user-specified name of the stream.
The same task can be accomplished remotely by clicking Switch to “StreamName” button on the µCEM Real-
Time Web page.

CEM Settings
The µCEM Settings dialog is only available to users with µCEM Settings permission. If a user is not currently logged in, the login dialog will be displayed. If the current user doesn’t have µCEM Settings permission, µCEM will not allow Settings screen to appear. When the µCEM Settings are invoked from the Advanced menu or the
µCEM Settings button, the µCEM Settings tabbed dialog is displayed. The Range page (tab) is displayed initially.
4.3.1
µCEM Settings-Range
The Range Settings page is used to specify the range for the analog outputs. Only range 2 can be set on this screen. Setting Range 2 to a value of 0 (zero) enables single range functionality and disables the dual range function. For Dual Range applications do not set range 2 equal too or higher than Range 1 or the
system will not calibrate properly. Note that Range 1 can be changed by the user but must be changed in the webrowser tools. See the Webrowser user settings section.
The dual range setting will enable the analyzer software and diagnostics to perform two separate performance curves for each range thus enhancing the measuring capabilities of the analyzer. A dual range setting is desired for applications burning dual fuels or that may display high dynamic reading between the low and high of the day. The analog outputs will also support the dual range mode. When the emission is below the Range 2 value, the analog output will switch to Range 2 mode and the Range 2 value becomes the full-scale value of the analog output. The range indication digital output will change to the Range 2 state. When the emission is above the
Range 2 value, the output switches to Range 1 mode and the Range 1 value becomes the full-scale value of the output. The range indication digital output will change to the Range 1 state.

The Auto-Calibration settings are set on the Auto-Calibration page of the µCEM settings. If auto calibration is turned to the on position, then the user can select time and/or frequency of the auto calibration in the Auto
Calibration Frequency tab (4.3.3).
Note: Both manual and auto calibration need to be performed with the MicroCEM enclosure door in the closed position. If the door is opened then critical detector temperatures will vary which will cause a drift in the calibration. If the door is kept open long enough for temps to be constant at their setpoints then an open door calibration is acceptable. See section 4.7 “temp diagnostics”- for details on temperature setpoints.

µCEM Settings-Calibration Gas
The Calibration Gas values and Gas Bottle allocation may be set on the Calibration Gas page of the µCEM
Settings. This should be set whenever a Calibration Gas container is replaced or upon Startup of the system.
Calibration Gas Values:
R1Mid: This is typically used for CGA audits and not for daily calibrations. The specific calibration gas mid value (typically between 40% to 60% of range) is set in this space. The MicroCEM will perform mid calibration on Range 1 on this gas but will not perform any corrections. This box should typically be left blank. It is mostly used as a check.
R1Span: The specific calibration gas span value (typically between 80% to 100% of range) is set in this space for Range 1. A Nox range of 0-100ppm would typically use a gas bottle with 90ppm NOx balance N2.
R2Mid: This is typically used for CGA audits and not for daily calibrations. The specific calibration gas mid value (typically between 40% to 60% of range) is set in this space. The MicroCEM will perform a mid calibration on Range 2 on this gas but will not perform any corrections. This box should typically be left blank.
It is mostly used as a check.
R2Span: The space is allocated for dual range applications. If the MicroCEM range setting is set for single range then the user will not be able to input any value into this space. The specific calibration gas span value
(typically between 80% to 100% of range) is set in this space. A Nox range of 0-10ppm would typically use a gas bottle with 9ppm NOx balance N2.
Note that zero values do not have to be input into this page. For all zero calibrations the user must assure that the calibration gas used does not have any levels of the measurement gas in the cylinder. For example upon the analyzer zeroing O2, the bottle used must have 0% O2 in the Bottle. Zeroing the O2 is typically performed by using the NOx or CO Span gases.
Gas Bottle Allocation:
Gas 1, Gas 2 and Gas 3 are labels for the respective location of where the calibration gas cylinders are physically located on the external fittings.
Off: Designates that no operation will be performed.
Zero: The MicroCEM will perform a zero calibration.
R1Span: MicroCEM will perform a Span calibration for Range 1.
R2Span: MicroCEM will perform a Span calibration for Range 2. Note that if a second range is NOT chosen in the range settings menu then user will not be able to input any value into this space. Range 2 should always be a lower value than range 1 if used.
R1Mid: MicroCEM will perform a Mid Calibration for Range 1.
R2Mid: MicroCEM will perform a Mid Calibration for Range 2. Note that if a second range is NOT chosen in the range settings menu then user will not be able to input any value into this space.

Choosing maintenance mode will invoke an “M” flag” onto the data. Customer can perform routine maintenance while in this setting
This mode is typically used when preventive maintenance is being performed. The M flag signifies to the EPA that the values reported are not valid therefore should not be applied to emissions reporting.
Upon completion of Maintenance the user must go back into this screen to turn the Maintenance off. If not, the
MicroCEM will continue to show the M flag in the data.

If desired a partial calibration may be invoked for one or more of the emission types. While the manual calibration is in process, a calibration progress dialog will be displayed as shown in Figure 4.13. When the manual calibration is completed, the results are displayed in the Manual Calibration Results dialog as shown in Figure 4.10. If the
Local Calibration checkbox is checked, the Local Calibration valve will be used during the calibration rather than the probe Calibration valve.
Note that “Start Auto Cal now” will invoke a calibration and will apply new correction factor to all measurement when done.

4.6 uCEM Data Logs
The µCEM maintains a minimum of 3 months of history in three types of data log files. The first type of log file is the measurement log, which contains emission measurements (at 1 minute intervals), alarm indications and maintenance mode indications. The second type of log file is the calibration log file, which contains information on each auto calibration done. The third is the alarm log file, which records any improperly functioning hardware. The data will be stored in flat, ASCII, CSV (comma-delineated) files. This file format can be read directly by MS Excel and imported into many types of software applications. The following parameters are factory set for each of the log file types.
4.6.1 Maximum Log File Size
This is how large a log file can get (in bytes) before it is closed and a new log file is opened.

4.6.7 Accessing the Real-Time ACSII Data String via Ethernet TCP/IP
(DAS)
Remote Real-time data acquisition from the uCEM is done through the TCP/IP enabled network via the HTTP (Web transport) protocol.
Acquisition software has to request the page from the Web Server running on the uCEM unit with the desired frequency (real update time is 1 sec).
URL for the real time data is defined as such: http://[uCEM IP]/fetchData.asp
For example: http://127.0.0.1/ fetchData.asp
In response Web Server will return the comma-delimited string that contains current analyzer data. Note: the response is a plain text not the HTML document.
If the actual analyzer software is running, the response data will be formatted as such:
DateTime, StreamNumber, SecondsRemaining, O2CurrentValue, O2CurAlarms, O2Status,
O21MinAverage, O21MinStatus, O215MinAverage, O215MinStatus, COCurValue,
COCurAlarms, COCurStatus, CO1MinAverage, CO1MinStatus, CO15MinAverage,
CO15MinStatus, NOxCurValue, NOxCurAlarms, NoxCurStatus, NOx1MinAverage,
NOx1MinStatus NOx15MinAverage, NOx15MinStatus, ExtProcess1, ExtProcess2,
ExtProcess3, ExtProcess4, DigInput1, DigInput2, DigInput3, DigInput4, DigInput5,
DigInput6, CalSeqNumber; AlarmsString
The result is a single string of data.
DateTime is formatted as such: Month-Day-Year4Digits HoursMilitary:Minutes:Seconds
Example: 02-05-2002 14:58:53
StreamNumber is a number that denotes a current stream (stack). It can take a value of “1” or
“2”, corresponding the stream number currently active.
SecondsRemaining is number of seconds left for current stream. It will equal to “##” if no automatic stream switching is happening.
All the current and average gas values are the floating-point numbers and may contain a sign.
Certain rules are defined for the current and average gas values:
If there is a “#” sign in this field – data for this field are not valid. That usually means there is no data available or the data cannot be converted to the string representation (due for example to faulty Calibration).
If the value field shows – “-555.00” (negative 555.00). That is a “magic number” that denotes that the system hasn’t yet initialized the data. That usually happens when uCEM starts up and 1 minute or 15-minute averages are not yet available (calculated). Note that regardless of the status, values show the current measured data from the analyzer. “Magic number” means that the data
(usually 15 minute averages) have not been yet calculated.
ExtProcess1, ExtProcess2, ExtProcess3 and ExtProcess4 are the values of the Analog Inputs
(Mega Watts and Fuel Flow usually).
DigInput1, DigInput2, DigInput3, DigInput4, DigInput5, DigInput6 - show the state of the digital inputs and can take a value of either 1(On) or 0(Off). DigInput1 is usually interpreted as
ProcessOn. DigInput2 – as FlameOn. DigInput3 – as Shutdown. Meaning of DigInput4,
DigInput5 and DigInput6 are to be defined.

CalSeqNumber – Calibration Sequence Number during the Calibration Process. Posible
values are:
0 - No Calibration is currently run
1 - Blowback 1 is in Process
2 - Gas 1 is in Process
3 - Gas 2 is in Process
4 - Gas 3 is in Process
5 - Blowback 2 is in Process
CurAlarms values show the current state of the emissions limit alarm associated with the
gas. It’s an integer number that equals to 1 when emission limit for the gas is exceeded and stays 0 if the gas doesn’t give associated alarm active.
All the Status values are single-character values. Status is defined as such:
V – Valid
I – Invalid
M – Maintenance
C – Calibration
P – Process Off
O – uCEM Off
B – By-Pass mode
AlarmsString – is a string data that describes the current Alarms situation with the uCEM module. It is separated from the rest of the data by a semi-colon. Example: “1,NOx Emission
Failed. 13 More ...”. First number could be either 1 or 0 and indicates whether or not Trouble light is on.
Example:
02-05-2002 14:58:53,1,75,21.44,1,V,20.09,V,-
555.00,V,##.##,0,P,##.##,P,##.##,P,10.37,1,I,
12.45,I,-555.00,I,5.0,3.76,4.5,0.75,0,1,0,1,0,1;1,NOx Emission Failed. 13 More ...
This string means that the sample was taken February 5 2002 at 2:58PM. System was running Stream 1, which a t the time had 75 seconds to run before a switch to stream 2.
O2 values were all Valid except the 15 Minutes average was not yet calculated, CO process was Off - the data were not available. NOX data were Invalid and the 15 Minutes average was not yet calculated. Mega Watts value read from the input was 5.0, Fuel Flow
– 3.76,. ExtProcess3 and ExtProcess4 were reading 4.5 and 0.75 respectively.
DigInput1(ProcessOn) is set to 0(Off), DigInput2(FlameOn) is set to 1 (On),
DigInput3(Shutdown) is set to 0 (Off). Digital Inputs 4,5 and 6 were reading 1,0 and 1 respectively.

STARTUP and OPERATION
There were also 13 alarms active, NOx Emission Failed being the most recent one.
Trouble light was On.
If the uCEM analyzer is not currently running the return string will be:
“uCEM is not running. No data Available.”
Acquiring Real Time Data for two Streams separately
Remote Real-time data acquisition from the uCEM-TS can also be done by requesting two streams separately. URLs for the ASCII strings are:
http://[uCEM IP]/fetchData1.asp - for Stream 1
http://[uCEM IP]/fetchData2.asp - for Stream 2
In response, Web Server will return the comma-delimited string, formatted in the same way as above, except StreamNumber value is called StreamActive. StreamAcitve indicates whether the requested Stream is currently active with 0 – Inactive, 1- Active.
If the requested stream is Inactive – uCEM-TS will return the Last Good Values and Last Good
Flags for one-second gas averages.

4.7 Viewing Data via the Pocket PC Web Browser
The Pocket PC Web Browser menu can be accessed via the pocket pc main menu. In the top upper left hand corner of the menu the name of the unit will be displayed (ucem XXXX). About this name, a drop down menu will appear. In Internet Explorer, a sign on page will then be displayed. User name and password will be the identical as the normal names used on the administration settings. Very importantly the Web Browser function allows the user to access all data (calibrations, alarms, emission data logs, diagnostics) internally stored in the MicroCEM.. If the user name and password screen do not pop up you may have to type in the proper IP address of the MicroCEM. Note: The standard Pocket PC
IP address is 206.111.230.252. This address enables the Pocket PC to be used on any MicroCEM unit no matter what the MicroCEM IP address.
The Web Browser will show the following screens/options for the user. Note that these screens are updated once every 10 seconds unless the refresh bottom is pressed:
Real Time: This screen is identical to the main menu screen normally shown on the pocket pc.
Emissions: This screen will enable the user to view all internal emission data logs stored in the
MicroCEM. User can choose between 1min, 15min, 1hr or 24 hour periods. A designated time frame or most recent data can be choices. The report generator will display data in a chart type format showing each gas value and associated time along with data flags. The function is very helpful in very historical data or performing trouble shooting.
Alarms: This screen will allow the user to display all alarms and time frames. User may choose time frames or most recent alarms.
Cal: Display of all calibrations with results can be viewed from this page.
User Config: This file contains user selectable files that are typically input at startup and never changed. See section 4.4 for details on descriptions. Note that reboot of the MicroCEM may be necessary for system to accept changes for several items in this file.
Factory Config: Do not access this file unless a certified Rosemount technician is present.
Changes to this file may adversely affect or destroy the unit. Changes made to this file without the written consent of the MicroCEM Product Manager will void the warranty.
Download: User can easily download all data log files (Emissions, Alarms, Calibrations) stored in the
MicroCEM. This is typically used when user is accessing the MicroCEM via a separate laptop or tabletop computer. See next section.
Temp Diag: Temperature diagnostics is a very important tool for diagnosing existing problems or potential issues/problems with the MicroCEM.
The following parameters will be shown: Temperature Parameter, Temp Setting, Actual Temp and
Integral %.
*Zone Temperature: Zone temperature is typically set to 47 degrees C. This is the temperature of the
MicroCEM taken from the detector section thermocouple that is located behind the pressure gauge.
This thermocouple is always used for systems with no CO. For systems with CO a thermocouple is located on the CO assy detector. The MicroCEM will typically control temperature to within +/- 0.1 degree C. Depending upon the outside ambient temperature the % on time can be from 0 to 100% on.
If a negative value is shown in the integral then cooling is in process. Variations greater than 0.1 degree
C will lead to gas measurement drifting.
*O2 Heater Temp: This is the Temperature of the chassis of the MicroCEM. Thermocouple is located in the PMD detector. Temperature is typically within 2 degrees C. of the zone. If the temperature drifts greater than this. Upon first turn on of the MicroCEM this temp can be monitored. Once this temp is within 2 degrees C of the Zone then the unit is ready for accurate measurements. Temperature above the 2 degree variance of the zone may show that the AC/Heater unit fan failed, or a thermocouple may be defective.
Rosemount Analytical
µCEM
Continuous Analyzer Transmitter 4-34
STARTUP and OPERATION
*PDD Peltier Cooler Temp: For systems with Nox, a cylindrical NOx detector assy is located in the detector section. Internal to the detector assy a small peltier device is operating and must operate at 0 degrees C. The temperature should never deviate more than +/- .05 degrees C from the setpoint of zero or the NOx readings may drift. Integral will typically run between 40 to 70%.
*PDD Chamber Heater: This temperature is for the detector assy heater core. Setting is set to 52 degrees C. Temperature should not drift more than 0.2 degrees C or NOx drift may occur. Excessive temperature variation may be caused by either poor zone temperature control or a faulty heater.
*Converter Temp: This temperature is for the NOx converter assembly. Temperature setting is 330 degrees C. Temp should not vary more than 1 degrees C. or NOx measurements will drift. A faulty heater will cause temp variations.
Note that when the enclosure door is opened that all of the above temperature setting may be affected and will take a short amount of time to react and control to the desired temperatures.

WARNING: PARTS INTEGRITY
Tampering with or unauthorized substitution of components may adversely affect safety of this product. Use only factory-approved components for repair.
WARNING: ELECTRICAL SHOCK HAZARD
Disconnect power to the module(s) prior to replacing components.
The uCEM Analyzer Module requires very little maintenance during normal operation.
5.1 Overview
The uCEM Analyzer Module requires very little maintenance during normal operation.
Occasionally, the detector's reaction chamber and sapphire window may require cleaning, refer to Section 5.7.
White crystal deposits on the windows of the reaction chamber and plugging of capillaries and vent are usually due to sample contaminates such as ammonia reacting with the high ozone levels and NO components. To eliminate the contaminates, the sampling system should be reworked or a preventive maintenance program developed (if dropout is not excessive). Another source of crystalline formation is contaminated air.
Several components may require replacement. These are discussed in the following sections.

NSTALLATION
:
To replace the photodiode, carefully remove the diode from the green socket, and replace with a new one.
Before mounting the new diode, the top cap of the enclosure should be temporarily removed and the (2) screws holding the Reaction Chamber loosened about two turns. This allows air which is trapped between the O-ring seals to escape when the diode is inserted. It also maintains the position of the O-ring and window in the upper compartment.
The new photodiode should be slowly inserted into the housing while gradually rotating the body. This allows the O-ring to properly seat. Continue replacing screws, washers, thermistors, etc., with the thicker shim (washer) on the opposite side of the socket from the thermistor.
Replace the lower section of the housing, then the bottom cover, insulator and bracket with the shoulder washers and screws.
Re-tighten the screws in the Reaction Chamber (upper section). Replace the top cap and its screws.
To reinstall in the Analyzer Module, reverse the procedure for removal as indicated above.

5.6.2 Analog/Digital I/O Board
The Analog/Digital IO (ADIO) Board is an off-the-shelf, complete data acquisition system in a compact
PC/104 packaging. The analog section contains 32 input channels, multiplexed A/D converter with 16 bit resolution and 10uS conversion time. Input ranges are +/-5v or +/- 10V. It also includes on-board
DMA support. The analog output section includes two 12 bit D/A converters. Both sections features simplified calibration using on board programmable digital potentiometer. The digital I/O section provides 24 digital I/O lines, which feature high current TTL drivers. The board requires only +5V from the system power supply and generates its own +/-15V analog supplies on board. The board operates over the Extended Temperatures range of -25° to +85°C. Figure 5-6 depicts the ADIO board and Figure 5-8 depicts the ADIO block diagram.

5.6.2.2 Automatic Calibration
The ADIO board features automatic calibration of both analog inputs and outputs for enhanced accuracy and reliability. The potentiometers, which are subject to tampering and vibration, have been eliminated. Instead, all
A/D calibration adjustments are performed using an octal 8-bit DAC. The DAC values are stored in an
EEPROM and are recalled automatically on power up. The board includes three precision voltage references for negative full scale, zero, and positive full-scale. A calibration utility program provided with the board allows you to recalibrate the board anytime, in both unipolar and bipolar modes, and store the new settings in
EEPROM.
Autocalibration applies to the 4 D/A channels as well. The full-scale D/A range is selected with a jumper block.
The analog outputs are fed back to the A/D converter so they can be calibrated without user intervention. Again, calibration settings are stored in EEPROM and automatically recalled on power-up.
5.6.2.3 Analog Inputs
The ADIO board provides split configuration capability, with more total input channels than any other PC/104 analog I/O board. The board can be user-configured in any of three ways:

5.6.2.5 Enhanced Trigger and Sampling Control Signals
The ADIO board has an extra A/D trigger and sample control signals in the design. Seven auxiliary digital I/O lines on the analog I/O connector provide a sample/hold output signal, A/D trigger in and out lines (to enable synchronization of multiple boards) and external A/D clocking.
The ADIO board contains 4 12-bit analog outputs with autocalibration capability. Up to 5mA of output current per channel can be drawn from all channels simultaneously. Both unipolar and bipolar output ranges are supported with jumper configuration. And on power up, all outputs are reset to 0V automatically.

5.6.2.7 FIFO and 16-Bit Bus Interface
An on-board 1024-byte FIFO enables the ADIO board to work with Windows 95 and NT by dramatically reducing the interrupt overhead. Each interrupt transfers 256 2-byte samples, or half the buffer, so the interrupt rate is 1/256 the sample rate. FIFO operation can be disabled at slow sample rates, so there is no lag time between sampling and data availability. The 16-bit interface further reduces software overhead by enabling all 16 A/D bits to be read in a single instruction, instead of requiring 2 8-bit read operations. The net result of this streamlined design is that the ADIO board supports gap-free A/D sampling at rates up to 200,000 samples per second, twice as fast as our previous boards.

SOFTWARE
6.
µCEM Software
The
µCEM Software includes 3 main components. One component is the µCEM control software that interfaces with the instrumentation and records the emissions measurements. A second component is the User
Interface Software that provides real-time status and configuration dialogs. A third component is the web server software that uses VB Script or Java Script to provide a web-based interface to the
µCEM.
6.1
µ
CEM User Interface Software
Hardware Platform Pocket PC
The
µCEM User Interface Software communicates with the µCEM Control Software using TCP/IP. It may run locally on the
µCEM computer or remotely on a Pocket PC with a RS232 connection to the µCEM computer. It will not normally run locally since there is no input device or display connected to the
µCEM processor.
6.2
µ
CEM Web Server Software
Web Browser Requires Internet Explorer 4.0 or Netscape 4.0
The Web Server Software provides the web based interface described in this document. It is implemented as a
VB Script or Java Script. The script will obtain much of the needed information directly from the Data-Log files or configuration file. The real-time information will be obtained from a memory segment shared with the
µCEM control software. The web server supports multiple simultaneous clients. The maximum number of allowed connections could be limited to a reasonable number through the Windows CE Web Server configuration dialogs. uCEM User

CEM Pocket PC Connection Failure
In the event of the connection with the
µCEM failed, a connection failure dialog will be displayed. It will display the following message.
Connection with
µCEM Lost, Retrying…
A Cancel button will be displayed. The
µCEM software will continue to attempt to reconnect with the µCEM indefinitely and will stop when a connection is made or the cancel button is pressed.
If the Cancel button is pressed, any setting changes that were made without pressing OK to accept will be lost.
If Auto Calibration was in process, it will be completed by the
µCEM even though the connection was lost.
