11. Select a filter and click Delete to delete the filter.

Automatically Reapply the Sample Filter

"Automatically Reapply Sample Filters" should be used to reapply filters that select different samples at different times. For example, if you create a filter called "last month's samples" that displays samples from the previous 30 days, it will show samples from the last 30 days when it’s first applied. If it’s not reapplied for another 60 days then by that point it will have samples from the previous 90 days—the samples that originally matched the filter plus all the new ones added since. To prevent this from happening, automatically reapply the filter every day, preferably at a time when the instrument isn’t being used.

The start time is the first time the sample filter will be refreshed. The frequency controls subsequent refreshes. If you set the start time to today at 8:30 PM, then if you set the refresh to every 12 hours it will refresh at 8:30 PM tonight, 8:30 AM tomorrow morning, 8:30 PM tomorrow night, etc. If you set the refresh to every 2 days, then it would update at 8:30 PM tonight, 8:30 PM two days from now, etc.

Operation Guidelines

Listed below are guidelines that should be followed before analysis, after analysis and after use. By using this information, along with the procedures in the Operation Chapter, the operator will be able to obtain the best possible performance from this instrument.

• Do not turn the AC power off to the instrument unless it malfunctions or it's not going to be used for an extended period of time.

• If the gas is turned off for eight hours or more, do not perform an analysis until the gas has been turned on for at least one hour.

• The piston should be left up with the crucible removed when the furnace is not in use.

• Refer to Before Analysis for before analysis guidelines.

• Refer to After Analysis for after analysis guidelines.

• Refer to After Use for after use guidelines.

Note


Before an Analysis

Before a sample can be analyzed and an accurate result obtained, the instrument must be prepared for analysis. This includes inspecting and cleaning the combustion system o-rings, performing a system leak check, selecting or creating a method, performing a blank calibration and then performing a standard calibration.

• This procedure prepares the instrument for analysis, not the sample. Refer to Sample Preparation on page 5–10 for sample preparation procedures.

• Some of the following procedures can be performed from the DSP Keypad or from Windows®. Refer to the pages that apply to your instrument.

1. Perform daily maintenance before the start of analysis.

A. Inspect and grease the Combustion O-rings. Refer to Combustion Zone O-rings, page 6–16.

B. Clean the Autocleaner and Mesh Filter. Refer to Autocleaner, page 6–6.

C. Perform a Leak Check. Refer to page 8–10 or 8–19.

2. Verify that the gas is turned on.

3. Verify that the oven is on and reached the proper temperature. Refer to Ambient Monitor, page 8–5 or 8–22.

4. Select or create a Method to use for analysis. Reference application notes to determine the method parameter values to enter. Refer to Method Development page 4–32 or 4–53.

5. Analyze 3 to 5 blank conditioning samples. This will purge the system before analysis.

6. Analyze 3 to 5 blanks and perform a Blank Calibration. This will set the blank calibration value. Refer to Blank Calibration page 5–33 or 5–77.

7. Analyze a Blank Check Sample to determine if the blank value was set properly. Refer to Login a Sample page 5–23 or 5–63.

8. Perform a Drift Correction and analyze 3 to 5 standard samples. This will set the drift correction value. Refer to Drift Correction page 5–81 (Windows® Only).

Notes


9. Analyze a Standard Check Sample to determine if the drift value was set properly. Refer to Drift Correction page 5–81 (Windows® Only).

10. At this point the instrument is ready for Sample Analysis. Refer to Analyze a Sample on page 5–25 or 5–68.

After an Analysis

When an analysis is complete, the furnace automatically shuts OFF, a signal sounds, and the spreadsheet shows the final result. If Line Printing and Automatically Print After Each Analysis is selected, the printer will print the analysis result. Refer to Configure the Analysis Report, page 4–48 (Windows® Only).

After Use

The AC power to the instrument should remain on at all times. If the power to the instrument is switched off for any reason a one-hour warm-up is necessary before analyzing samples.

The instrument automatically switches to conservation (low gas flow) after an amount of time specified by the Conservation Time-out in System Configuration, page 4–18 or 4–59.

Remove the crucible from the furnace after use.

• The furnace should be closed except when loading and unloading samples or when maintenance is being performed. If the furnace is left open for an extended period of time, analyze 3 to 5 conditioner samples before resuming normal operation.

Note


Crucibles

When analyzing for low carbon (<0.1%) or low sulfur (<0.01%), ‘burned off’ crucibles yield the best results. Crucibles are burned off by firing them at 1350oC (2500oF) for at least 20 minutes in a TF-1 or TF-10 Tube Furnace, then cooling them in a desiccator. Crucibles must be used within four hours of being burned off or the procedure must be done again.

After the crucibles have been “burned off” handle them with 761-929 crucible tongs to avoid burning your fingers or contaminating the crucibles.

CAUTION

!


Sample Preparation

DO NOT touch the crucibles or sample material. Touching them or letting dust accumulate on them will adversely affect analytical results.

Sample Size

The nominal sample weight is 1.0 gram. The lower and upper limits will depend on the sample material analyzed.

High Sulfur Samples

Reduced sample mass is required for samples with 40% or more sulfur content. For these samples use one scoop Iron Chip and one scoop Lecocel® to ensure complete coupling of the sample and RF field.

Blank Samples

Blank samples should be 1 scoop Iron Chip and 1 scoop Lecocel®.

CAUTION

!

Calibration

Calibration is the process that adjusts the instrument to produce an analysis result to equal that of a known calibration standard with the same concentration. First a Blank Calibration is performed, then Standard Calibration and then as daily maintenance both a Blank Calibration and Drift Correction.

Single point calibration calibrates the instrument to one calibration point. Multi-point calibration calibrates the instrument to a set of calibration points over an expected range of concentrations.

Blank Calibration

Blank Calibration is used to calculate the system blank or baseline. Sometimes this is called the blank area. Blank calibration calculates the system blank and compensates for it when calculating the analysis result. The system blank should be determined every day by performing a blank calibration before analysis. Refer to Blank Calibration on page 5–77.

Standard Calibration

Standard Calibration is used to calibrate the instrument with known calibration standards. A single point or multi-point calibration can be performed and the curve type selected although, LECO recommends multipoint, linear calibrations that employ 1/certified weighting. Additionally a blank calibration should be completed prior to performing a standard calibration. Since Standard Calibration is saved with each method, each method must be calibrated after it is created. Refer to Standard Calibration on page 5–78.

Drift Correction

Drift Correction is used to compensate standard calibration and account for variances in the instrument hardware that can slightly change the calibration. Drift correction should be performed at the start of every day. This insures accurate calibration and analysis results. Refer to Drift Correction on page 5–81.


Blank Calibration

Blank calibration calculates the system blank and compensates for it when calculating the analysis result. Refer to Calibration on page 5–76 for more information.

1. Login and perform at least three blank analyses.

2. Select the results of the blank analyses from the spreadsheet.

3. Click Configuration and select Blank. The Element Selection screen will appear.

• In the screen below, the software displays the data in blue to alert the operator that the data has changed.

• Step 4 can only be performed if more than one element is shown in the dialog box.

4. Include or exclude an element by clicking a row to select the element and clicking Include/Exclude. The action box will indicate if the element is included or excluded. If the element is included a blank calculation will be calculated for that element.

5. Click OK to calculate the system blank based on the analysis results obtained in step one.

Note

Note


Standard Calibration

Standard Calibration is used to calibrate the instrument with known calibration standards. Refer to Calibration on page 5–76 for more information.

• Refer to Standard Calibration Definitions on page 5–80 when performing this procedure.

• The instrument blank should be calibrated before performing standard calibration.

• LECO recommends that multipoint linear calibration that employs 1/certified weighting be used for standard calibration.

• Gas Dose analysis is very similar to standard calibration. The gas dose (loop) value, based on 100% CO2 (carbon only), is entered at the factory into the standards database on the instrument under the name “Gas Dose”.

1. Login and perform at least three standard analyses.

2. Select the results of the standard analyses from the spreadsheet.

3. Click Configuration and select Calibrations.

Notes


4. Click the arrow in the drop down box and Select a Cell (detector) to calculate a calibration for. A separate calibration can be calculated for each cell.

5. Click the arrow in the drop down box and Select a Curve Type. LECO recommends that multipoint linear calibration that employs 1/certified weighting be used for standard calibration.

6. View the curve displayed on the graph. It should intersect the black squares, which represent the standards. If you’re using multipoint calibration zoom in on each standard for the most accurate viewing.

7. Click the arrow in the drop down box and Select the desired Weighting. LECO recommends that multipoint linear calibration that employs 1/certified weighting be used for standard calibration.

8. Click OK to select the cell to calibrate. One or more cells can be selected.

Curve Type—Selects the type of calibration curve. Select a curve that intersects each calibration result. LECO recommends that multipoint linear calibration that employs 1/certified weighting be used for standard calibration.

Weighting—Determines which calibration results, on the calibration curve, get priority. LECO recommends that multipoint linear calibration that employs 1/certified weighting be used for standard calibration.

• Normal—Each point gets equal priority.

• Manual—A manual weighting can be entered.

• 1/Certified—A weighting factor that can be applied to the calibration data points. This will counteract a bias for higher concentrations that develops naturally from the curve fitting routines.

Show—Click Show to show the last calibration. The last calibration will appear on the graph in blue.

Manual—Click Manual to enter a new calibration equation. This can be done if a calibration was lost and a previous calibration recorded.

RMS Error (Root Mean Square)—A method of quantifying the dispersion or spread of data. It is used in the PC software to determine which calibration curve is a better fit. The lower the RMS error the better the fit.

Zoom In—Draw a box around a calibration point to zoom in.

Zoom Out—Click on a calibration point with the right mouse button. A Zoom Out button will appear. Click the Zoom Out button to zoom out.


Drift Correction

Drift Correction is used to compensate standard calibration and account for variances in the instrument hardware over a period of time that can slightly change the calibration. Drift correction should be performed at the start of each day. This insures accurate calibration and analysis results.

Perform standard calibration and choose the drift standards before performing a drift calibration. Refer to Calibration on page 5–76 for more information.

• A Blank Calibration should be performed before every Drift Correction. Refer to Blank Calibration on page 5–77.

Configure Result Plot

The CS230 Windows Software permits the operator to configure the result plot to show the desired result information on the plot as determined by the operator. The Configure Result Plot menu give the operator the choice of zooming out, zooming out one level, labeling plotted points, plotting the statistical points, and selecting an auto independent scale. Plot properties can also be selected from this menu.

Display the Menu

1. To display the Configure Result Plot menu, move the mouse pointer to the result plot and right click on the plot. The Configure Result Plot menu will appear.

2. Click on the menu selection to select or deselect it. A check indicates the item has been selected.

3. When finished, click on the plot to remove the menu.

Selection Procedures

Zoom In (not a menu selection)—Position the pointer (mouse pointer) over the area to zoom in on. Hold the left mouse button down and draw a box. The area inside the box will be magnified. Draw another box to zoom in farther. Zoom In cannot be used if the sample being analyzed is displayed. Wait until analysis is complete and then zoom in on the plot.

Zoom Out—Click Zoom Out to remove all steps of magnification.

Zoom Out One Level—Click Zoom Out to remove the last step of magnification.

Label Points—When result points are selected and displayed, the points can be numbered to show their relationship to the samples selected. The first sample selected is labeled number 1 and the remaining samples selected are numbered as they were selected from the spreadsheet. The number displayed on the plot is not the sample number displayed on the spreadsheet. Multiple samples and statistics (below) must be selected before this feature can be used.


Statistics—Changes the plotted result curves to plotted result points. A point is shown for each sample and represents the peak concentration. Multiple samples must be selected before result points can be plotted.

Auto Independent Scale—If multiple plots are displayed they will be scaled the same. This means if one plot is many times larger than one of the other plots the smaller plot may be hard to see or not seen at all. By selecting auto independent scale, all plots will be made the same height in order to compare one plot to another.

Properties—Click Properties to display the Plot Properties Configuration screen.

From the Properties screen you can select the Reporting Units, Significant Digits, Plot Pattern and Plot Color. You can also Hide the Baseline and Plot if desired.

General Information

The CS230 Carbon/Sulfur Determinator is a microprocessor based, software driven instrument for measurement of carbon and sulfur content in metals, ores, ceramics, and other inorganic materials. The CS230 uses an induction furnace and measures carbon and sulfur by infrared absorption.

Analysis begins by weighing out a sample (1 g nominal) into a ceramic crucible on a balance. Accelerator material is added, the crucible is placed on the loading pedestal, and the analyze key is pressed. Furnace closure is performed automatically, then the combustion chamber is purged with oxygen to drive off residual atmospheric gases. After purging, oxygen flow through the system is restored and the induction furnace is turned on. The inductive elements of the sample and accelerator couple with the high frequency field of the furnace. The pure oxygen environment and the heat generated by this coupling cause the sample to combust. During combustion, carbon bearing elements are reduced, releasing the carbon, which immediately binds with the oxygen to form CO and CO2, the majority being CO2. Also, sulfur-bearing elements are reduced, releasing sulfur, which binds with oxygen to form SO2.

Sample gases are swept into the carrier stream. Sulfur is measured as sulfur dioxide in the first IR cell. A small amount of carbon monoxide is converted to carbon dioxide in the catalytic heater assembly; SO2 is converted to SO3, while sulfur trioxide is removed from the system in a cellulose filter. Carbon is measured as carbon dioxide in the IR cell as gases flow through the IR cells.

The optional automatic autocleaner is ideal for high volume applications and reduces operator time. The autocleaner brushes the filter screen and combustion tube at intervals specified in System Configuration.


Infrared Radiation, Absorption, and Detection

The infrared (IR) source consists of nichrome wire that is resistance-heated to 850oC. The IR source radiates visible energy as well as all wavelengths in the infrared spectrum. The description below uses carbon dioxide although, the same principle applies to sulfur detection.

Carbon dioxide absorbs IR energy at a precise wavelength within the IR spectrum. Energy from the IR source is absorbed as the gas passes through the cell, preventing it from reaching the IR detector. All other IR energy is prevented from reaching the IR detector by a narrow bandpass filter. Because of the filter, the absorption of IR energy can be attributed only to carbon dioxide (CO2). The concentration of CO2 is detected as a reduction in the level of energy at the detector.

One IR cell is used as both a reference and for measurement. The total carbon, as carbon dioxide, is detected on a continuous and simultaneous basis. The cell consists of an IR source, chopper motor, a narrow bandpass filter, a condensing cone, an IR energy detector and the cell body. Radiated energy is chopped at a rate of 87.5 Hz. before it enters the cell body. The chopped energy enters the cell body through a window, travels through the cell body, then exits through a second window and a precise bandpass filter. The selective filter passes only the CO2 absorption wavelength into a condensing cone that concentrates the energy on the detector. The solid state detector is AC coupled to a preamplifier. As the gas concentration increases, the voltage to the preamplifier decreases.

The starting reference level, or baseline, for the detector is established by running 100% oxygen through the cell. The pure oxygen environment permits the maximum amount of energy to reach the detector. This maximum energy level is AC coupled to the preamp where it is amplified, rectified, and filtered. It is then sent to an A/D converter where the analog signal is converted to a digital signal. The nominal voltage read at the cell output, via the Ambient Monitor, is 8.500 VDC.

During every analysis, the computer reads the baseline. This level is then adjusted digitally until a nominal level is achieved. For example, if the cell output is 8.400 VDC, then this level is change digitally until the level reads 8.500 VDC. This level change is done in the computer and used for a reference, if the cell output voltage were actually measured, no change would be observed.


As analysis begins, the cell output decreases with the amount of carbon (as CO2) present in the cell. The computer reads the cell output 20 times per second and produces data points that are stored in memory. The computer then processes the curve or graph formed by these data points. The curve or graph is then used by the computer to calculate the element weight percent of an unknown sample.

Comparator Level

• One comparator level is associated with each analysis method. Selecting a different method also selects a new comparator level.

An analysis that lasts excessively long causes unnecessarily long delays, while an analysis that isn’t long enough can cause loss of significant analyte data collection. Since not all samples combust in the same manner, analyses should not be performed based on time alone.

The length of each analysis is determined on an individual basis by the minimum analysis time and the comparator level. Analysis ends when the minimum time limit is reached and the analyte rate drops below the comparator level after passing its peak. This comparator level is a preset constant (k) plus a percent of the peak:

COMPARATOR LEVEL = k + (X)(P)

P Detector output peak

X Selected comparator level percentage

During an analysis, the output of the detector is collected in the form of digital data and summed to arrive at the analysis result. If this data were plotted, it would reflect the curve of the detector output.

Note


Shown below are two examples of the same detector output curve (buffer plot). The first example shows the amount of detector output collected during an analysis with a comparator level setting at 6% while the second example illustrates at 25%.

The following conclusions can be drawn from the examples:

1. A high comparator level shortens analysis time.

2. A low comparator level includes more sample gas, and therefore more sulfur, into result calculations.

3. A comparator level that is too low, however, results in the inclusion of very low concentrations that don’t significantly effect the result (noise), but lengthen the analysis.

A comparator level of 1.0% usually provides optimum performance by allowing the collection of all significant output within a reasonable time.

Extremely low output peaks may need a larger comparator level to exclude insignificant output levels produced toward the end of analysis and cut down on drift. The minimum time should be extended to match what would be considered a reasonable time length for the analysis of such samples. The combination of a high comparator level and an extended minimum analysis time insures that all significant output is collected and analysis time lengths are consistent without being extensive.

Whenever the comparator level changes check the system calibration since interaction can occur.

Leak Check

This procedure automatically check the measurement system of the instrument for a gas leak. The entire system can be checked or the operator can by-pass the furnace to isolate the leak.

During a system leak check the system is pressured to 500 mm Hg above current system pressure and sealed. It is then permitted to equilibrate. For the next 60 seconds the system pressure is measured. If the pressure remains within 5 mm Hg of the pressurized value the system passes the leak check (for system check only). If the pressure changes more than 5 mm Hg of the pressurized value the leak check fails.

In the Leak Check Progress box the status of the leak check is displayed. If a leak check fails it may be caused by gas leaking into or out of the system.

If “Change in Pressure” has increased the incoming valve SV6 may be malfunctioning or the catalyst heater tubes are not at a steady temperature. If “Change in Pressure” has decreased gas is leaking out of the system.

If a leak is present, "Leak Check Failed" appears next to “Leak Check Status”. If there isn't a leak " Leak Check Passed" appears. If the system fails a leak check and a leak is detected, perform a “by-pass the furnace” leak check to isolate the leak.

Before a leak check is performed the instrument should warm up for at least for 30 minutes and the catalyst heater tubes must be at a steady temperature. It is recommended that a leak check be performed after autocleaner maintenance, furnace maintenance or anytime a reagent tube is removed or replaced.


Leak Check

1. Click Diagnostics and select Leak Check. The Leak Check screen will appear.

2. Click System Leak Check to perform a leak check on the entire measurement system or click By-pass Furnace Leak Check to perform a leak check of the measurement with the furnace bypassed. The result of the leak check will appear in the Results box.

3. Click Stop Leak Check to stop a leak check in progress.

4. Click Print to print the results of the leak check on the system printer.

5. Click View to look at various areas inside the instrument where a leak may be found.


Leak Check Definitions

Starting System Pressure—The operating pressure of the system before it is pressurized. The system pressure will not change as the system is being pressurized.

Initial Pressure—The system pressure at the start of system pressurization. Normally, initial pressure is the same value as system pressure.

Current Pressure—The system pressure at the current time. The current pressure changes rapidly as the system is being pressurized.

Change Pressure—The difference between the initial pressure and the current pressure. A negative number indicates an increase in system pressure. A positive number indicates a decrease in system pressure.

Elapsed Time—The length of time, in seconds, that the test has been running. Normally, after 60 seconds the test is complete.

Barometric (PID) Pressure Regulator Adjustment

This adjustment has been factory set to a highest anticipated barometric pressure of 762 mm. If the highest anticipated pressure in the operational environment varies more than ±5 mm from 762 mm, this adjustment must be performed to eliminate calibration shifts that may occur as a result of barometric pressure changes.

The present (operation environment) barometric pressure must be determined. If an accurate method of measurement is not available, the nearest weather bureau or airport can provide this information. The pressure must be referenced to the operational site altitude, not sea level. The highest anticipated pressure for the area must also be determined.

• The determinator power must be on for a minimum of 30 minutes prior to performing this adjustment.

• The furnace piston must be in the up position and the furnace power switch must be in the on position.

• This adjustment should be performed if the barometric pressure transducer or PID pressure regulator card is replaced.

1. Insure that the jumpers on the circuit board are installed as follows, see Figure 9-1, page 9–4:

A. J1—The two pins nearest transistor Q2 should be jumpered.

B. J2, J3 and J4—Both pins on each connector should be jumpered.

2. Insure that the controls on the circuit board are positioned as follows, see Figure 9-1, page 9–4:

A. R27—Set to 9.

B. R28—Set to 2.

C. R29—Set to 5.

3. Remove the left side panel of the determinator.

4. Turn the AC power on to both the determinator and furnace.

Catalyst Heater Control Card

HIGH VOLTAGE HAZARD After the side panels are removed, high voltage is present. Use caution when making these adjustments. Contact with voltages inside the instrument can be lethal or cause serious injury.

• This procedure adjusts the catalyst heater control card to ensure proper temperature tracking of the catalyst heater and to provide an accurate temperature read-out on the ambient monitor.

• This adjustment is only necessary when the catalyst heater card or heating element is replaced.

• To properly perform this adjustment, a digital voltmeter capable of measuring 7 volts is needed. Also, a calibrated thermocouple is necessary to externally measure the operating temperature of the catalyst heater.

1. Turn the analysis gas OFF.

2. Remove the left side panel of the unit to access the catalyst heater controller card.

3. Attach the negative terminal of the digital voltmeter to the metal chassis of the determinator where there is no paint. Be sure a good connection is made.

4. Attach the positive lead to pin 4 of connector J078A or pin 7 of U4. Refer to Figure 9-2, page 9–6.

5. Adjust control R16 until 3.5 volts is read on the digital voltmeter. At pin 4 of J078A, one volt equals 100oC.

6. Remove the digital voltmeter leads from the determinator.

7. Using protective gloves, remove the catalyst heater tube from the catalyst heater and set it on a heat-resistant surface.

• To remove the catalyst heater tube refer to page 6–11, steps 3 and 4.

WARNING

Notes

Note

2. Turn on the furnace service switch and verify that plate current is approximately 150 mA and grid current is approximately 100 mA on the analyze screen.

3. Turn off the service switch and verify that the plate and grid currents go to zero.

4. Turn the power level control clockwise to the max position.

5. Put a calibration load on the furnace pedestal.

• If the calibration load recommended and calibrated by LECO is not used during adjustment, the performance of this instrument cannot be guaranteed.

6. Press the piston switch on the furnace. The pedestal should rise.

7. Perform either step 7A or step 7B.

A. Enter a weight in the stack. When using this method, the minimum time-out parameter under the analysis method option in the setup screen should be extended to 120 seconds or more to allow ample time to perform the adjustments.

• Be sure to reset the minimum time-out to the original setting after the electronic adjustments have been performed.

B. Move jumper J1 on the card from pins 1 and 2 to pins 2 and 3. This will cause the furnace to turn on until the jumper is replaced on pins 1 and 2. Refer to Figure 9-3, page 9–9.

Note

8. Verify that turning power level control up and down (located on the front panel) causes the plate current to increase and decrease respectively. Return the power level control to the max position.

• If the power level control adjustments do not seem to affect the power level read-out, adjust R29 down and try adjusting the power level control again.

9. Adjust the overload control (R32) up (approximately 10 turns) to prevent the furnace from going into overload.

10. Adjust the offset control (R29) as follows:

A. If the oscillator current is below 500 mA, adjust R29 counterclockwise until 500 mA of plate current is obtained and then proceed to step 11.

B. If the oscillator is not oscillating, and the plate current is low, turn R29 clockwise until 500 mA of plate current is obtained.

C. With the power control at maximum, adjust R32 counterclockwise until the current overloads. Then gradually adjust R32 clockwise and R29 counterclockwise until the oscillator tube oscillates at 500 mA.

• Sometimes it requires a couple of attempts at this step if the oscillator gets into this mode of oscillation. Once the oscillator is set, it should function normally for the life of the oscillator tube.

11. Adjust the overload control, R32, down until the furnace power trips. Be sure the power has actually tripped and that the power has not merely turned off because the analysis has ended. Verification can be accomplished by observing that LED1 is lighted.

12. Turn the overload control back approximately 11/2 turns to ensure that the furnace will go into overload just above the full-scale current setting of 500mA.

13. Reset the overload by turning the power level control to reset and then back to max. Now the furnace should not go into overload when the power level control is returned to max.

Safety Pressure Adjustments

HIGH VOLTAGE HAZARD After the left side panel of the unit is removed, high voltage is present. Do not touch any component inside the cabinet when performing this adjustment unless instructed to do so.

• Piston safety pressure (6 psi) is applied to the pneumatic piston except when the piston is fully extended.

• The pneumatic piston closing speed increases as pressure increases.

1. Access the analyze menu and select Manual Operation.

2. Remove the left side panel and locate the piston pressure regulator. Refer to Figure 11-1, page 11-3.

3. Press the up/down switch and open the furnace. Observe the speed of the piston while the piston is in transit. If the piston does not travel from top to bottom and bottom to top in approximately two seconds locate the safety pressure adjustment knob, Figure 10-3, page 10–7 and adjust as follows:

A. If the piston travel is too slow:

1) Cycle the furnace piston by pressing the up/down switch and rotate the safety pressure adjustment knob clockwise while observing the speed of the piston.

2) The time for piston travel should be approximately two seconds.

3) Cycle the furnace piston by pressing the up/down switch twice.

4) The time for piston travel should still be approximately two seconds.

5) Press the up/down switch to close the furnace and complete this procedure.

WARNING

Notes


B. If the piston travel is too fast:

1) Cycle the furnace piston by pressing the up/down switch and rotate the safety pressure adjustment knob counter-clockwise while observing the speed of the piston.

2) The time for piston travel should be approximately two seconds.

3) Cycle the furnace piston by pressing the up/down switch twice.

4) The time for piston travel should still be approximately two seconds.

5) Press the up/down switch to close the furnace and complete this procedure.

FIRE HAZARD Oxygen increases the flammability of materials. Always use caution when adjusting or operating units using oxygen supplies. LECO recommends routine leak check procedures to reduce the possibility of fire hazards.

Vertical Crucible Alignment

• To assure efficient lance flow to the sample, and optimal sample coupling, with the high-energy field around the coil, the crucible must be properly positioned on the pedestal.

ELECTRICAL SHOCK HAZARD The capacitors on the oscillator chassis store a lethal amount of energy and must be discharged to avoid electric shock . Contact the LECO service department for more information before servicing the oscillator chassis.

HIGH VOLTAGE HAZARD After the power has been turned on, both the oscillator and the furnace power supply produce lethal voltages. Contact the LECO service department for more information before servicing the oscillator chassis.

1. Place an empty crucible on the furnace pedestal and close the furnace.

2. Observe the crucible position through the furnace screen. The bottom of the crucible should be located just below or even with the lower portion of the third coil turn from the top. Refer to Figure 10-4 page 10–11.

3. If the crucible is not in the proper position, it will be necessary to adjust the induction coil.

A. Place the furnace’s power on/off switch to the off position and unplug the furnace power cord from facility power.

Gas Flows

Analysis

Analyze Valve State—In this valve state, oxygen flows through both the furnace and the determinator system.

When the gas is turned on, oxygen, regulated at 35 psi at its source, enters the determinator through the O2 inlet port on the cabinet back panel. Oxygen flow is then filtered through a 6 inch bubble tube (located on the front of the furnace) containing Lecosorb and anhydrone. Carbon dioxide is removed from the oxygen flow using Lecosorb reagent and moisture is removed in the anhydrone reagent. Oxygen, with all impurities removed, serves as the carrier gas in the system.

After all impurities have been removed from the carrier gas, the flow is divided into two paths; one path, the lance flow, is directed through solenoid valve 3 and into the top of the combustion tube. During an analysis, lance flow is held constant and is directed into the sample to assist carbon-bearing components to convert into CO or CO2. The second path is directed through solenoid valve 5 into the bottom of the combustion tube; this flow rate varies (2 to 3 lpm) in accordance with each valve state.

The carrier gas flows from the combustion tube sweeping released gases from the combustion tube through a screen filter, then through a 4 inch filter tube containing anhydrone to remove water. The carrier gas, regulated by a flow controller in the oven, flows through the catalyst heater. A small percentage of the carbon is present as carbon monoxide, which is converted to carbon dioxide as the gas flows through the platinized silica gel in the heater. Sulfur trioxide is removed in a cellulose trap. Gas then flows through the cellulose trap, CO2 IR cell and solenoid valve 15. It is then exhausted out the back of the unit.

Furnace Open 1 Valve State—In this valve state, the combustion tube is depressurized so that residual dust can be ejected.

Lance flow remains the same as in the analyze valve state, but the measure flow is bypassed through both solenoid valve 9 and solenoid valve 2. Flow through solenoid valve 9 is briefly purged through the combustion chamber while flow from solenoid valve 2 passes through the cellulose trap and IR cell as previously described for the measure flow. Pneumatic gas flows through the safety pressure regulator. With solenoid valve 9 open, the lance and purge flow (through solenoid valve 9) ejects residual dust from the combustion tube.


Furnace Open 2 Valve State—In this valve state, the piston moves down and, if selected, the vacuum turns on.

Lance flow is on while measure flow bypasses the furnace altogether and flows directly through solenoid valve 2 and is directed to the IR cell. Pneumatic gas is switched through the safety pressure regulator and solenoid valve 10 causing the piston to be lowered. In addition, the vacuum solid-state relay switches on if it has been selected.

Furnace Open 3 Valve State—In this valve state, the vacuum, if selected, shuts off and the furnace remains open to load the next crucible on the pedestal.

Flow is identical to Furnace Open 2 Valve State, but the vacuum solid state relay switches the vacuum cleaner off.

Furnace Closed 1 Valve State—This valve state is triggered when a loaded crucible is placed on the piston and the piston up/down key is pressed. The piston moves up under low pressure until the up piston limit switch closes.

Oxygen flow completely bypasses the furnace through solenoid valve 2 and is directed through the cellulose trap and IR cell. Pneumatic gas flows through the safety pressure regulator and closes solenoid valve 10 to move the piston up.

Furnace Closed 2 Valve State—In this valve state, the lower seal changes to high pressure and is sealed against the combustion tube o-ring. Atmospheric gases are quickly purged out of the combustion tube.

Lance flow is on and measure flow is on through the IR cell as well as purged through the top of the combustion tube. Pneumatic gas allows atmospheric gases to be purged from the combustion tube.

Furnace Closed 3 Valve State—After a pre-analyze purge delay, the combustion tube is pressurized in this valve state.

Oxygen flow is identical to that in Furnace Closed 2 Valve State, but pneumatic flow goes through solenoid valve 9 only.

Analysis Valve State—Following Furnace Closed 3 Valve State, there is a 2 second delay, after which the CPU checks that the lance pressure switch is closed and a weight has been entered in the weight stack. If both conditions are affirmative, the system goes into Analyze Valve State, (previously discussed). During a preanalyze delay, a stable IR baseline is obtained, after which IR zeros are taken. Integration begins just before the furnace is heated. As the sample is combusted in the furnace, sample gases are mixed with the carrier gas (oxygen) and CO2 is collected and released by the trap. Then the gas is directed to the IR cell. Percent carbon is displayed on screen, the furnace shuts off, and the answers are saved in memory and then printed.


Post-Analyze Valve State—In this valve state, lance flow is shut off while measure flow remains on to maintain a constant flow through the IR detection system.

Lance flow is off, while measure flow is directed into the bottom of the furnace and subsequently through the IR cell. The piston remains raised under pneumatic pressure.


Autocleaner

After a programmed number of analyses, the furnace must be cleaned, either manually or automatically, to prevent excessive residue buildup. The following procedure generally describes both manual and automatic cleaning cycle flows; however, in system controls, several autoclean options can be selected. Refer to the System Controls procedure on page 5–16 and System Configuration on page 4–59, for details.

In each of the three clean valve states, oxygen flow is bypassed through the IR cell, the piston is down, and the door is closed. Differences in these valve states include vacuum cleaner on or off and brush up or down.

A clean cycle is begun by pressing [5] Clean from the analyze menu. If the cup is up, the combustion tube is depressurized (Furnace Open 1 Valve State) and the lance pressure switch opens. If the piston switch is down, Clean 1 Valve State is signaled and the furnace door closes.

If an autocleaner has been installed, the vacuum turns on, the brush moves down (Clean 2 Valve State) and up (Clean 1 Valve State), and then the cycle repeats 2 times. If manually cleaning, the vacuum switch shuts off automatically (Clean 3 Valve State) and the vacuum switch is pressed manually to begin cleaning. After cleaning the filter and combustion tube, the vacuum switch is shut off manually. Then [5] Clean is pressed and the furnace door opens (Furnace Open 3 Valve State).

The cycle is completed when atmospheric gases are purged from the system (gas flows for each valve state have been previously discussed). After cleaning, the vacuum is shut off (Furnace Open 3 Valve State), the clean switch is pressed, and the cup moves up under low pressure (Furnace Closed 1 Valve State). The cup then goes to high pressure, sealing the piston against the o-ring. Atmospheric gases are purged from the combustion tube (Furnace Closed 2 Valve State) and after a purge delay, the combustion tube is pressurized. Finally, after a two second delay, oxygen flows through both the furnace and determinator (Post Analyze Valve State).

Software Upgrade

A major portion of the determinator's functions are defined and controlled by a software program that may be updated. Most updates do not affect the physical design of the determinator, but can improve performance and make operation easier. Therefore, an identification system for program changes called 'Program Version' is used in the CS230 Carbon and Sulfur Determinator and other LECO instruments.

A three-digit number identifies program version levels. The first generation of a program is version '1.00'. Each time a program is changed, the version number is increased.

• The following procedure is for DSP instruments. For Windows® instruments refer to Software Upgrade with Windows® on page 10–29.

DSP Software Upgrade Procedure

• When installing new EPROMs, be careful not to bend any of the EPROM pins out of the socket or under the EPROM.

1. Place the determinator's power on/off switch in the off position and disconnect from facility power.

ELECTRICAL SHOCK HAZARD The CS230 operates from 230V~. Contact with this voltage can be lethal. Disconnect the determinator from the facility power source before removing the side panels.

Keypad

Note

WARNING


2. Remove the left side panel of the determinator to expose the CPU circuit board. Refer to Figure 10-10, page 10–28.

ELECTRICAL SHOCK HAZARD After the side panel is removed high voltage is present. Use caution when making these adjustments. Contact with voltages inside the instrument can be lethal or cause serious injury.

3. Locate the program EPROMs IC3 and IC4. With a small flat tip screwdriver, pry the old EPROMs from their sockets. Discard the EPROMs.

4. Install the new program EPROMs in sockets IC3 and IC4. Install the low EPROM in socket IC4 and the high EPROM in socket IC3.

• Make sure the notch at the end of the EPROM is located over the half circle screened on the CPU circuit board.

5. Reinstall the left side panel of the determinator.

6. Turn the AC power on. The Copyright screen should be displayed.

7. After approximately 10 seconds the Reset Confirmation screen will be displayed. Answer Yes to all questions. All system parameters will be set to their factory default values.

8. If desired, enter the old system parameter values printed from System Parameters. The barometric pressure should be set.

9. Proceed with setup and operation of the determinator.

Linearization with Windows®

• The following information is for Windows® instruments. For DSP instruments refer to Linearization on page 10–30.

The output signal (voltage) from the IR cell detector is not linear with respect to element concentration. To make the output of the IR cell appear linear, each cell is linearized by LECO during the manufacturing process.

• It is only necessary to perform this procedure if an IR cell is replaced. The break and slope values to enter during this procedure can be found on a tag attached to the replacement IR cell.

1. Click Configuration and select Linearizations. The linearization dialog box will appear.

Note

Windows®


2. Click the arrow in the Select Cell drop down box and select the IR cell to linearize. Selections are Carbon Low Range, Carbon High Range or Sulfur.

3. Click on the table and enter the break and slope values. The determinator will calculate the adjusted break value.

4. Click OK to save the adjusted break value and exit this procedure.
