1.1.2 System Introduction The Roche Diagnostics cobas e411 Immunoassay System is a fully automated, software-controlled system for immunoassay analysis. It is designed for both quantitative and qualitative in vitro determinations using a large variety of tests for analysis. To assist you in quickly identifying which component is specific to either the disk or rack system, one of the following graphics appears to the right of the subsection header. If no graphic appears next to the header, then that component is common to both systems.

Clot detection is accomplished by a pressure transducer. A new AssayTip is utilized with every new pipetting sequence. For example, TSH = 1 tip for R1, R2 and sample, then one new tip for microparticles. The tip is washed externally at the rinse station between each aspiration. Additional tips are used for sample dilutions or pretreatment.

1.1.8 Mechanical Theory 1.1.8.1 Introduction The cobas e411 analyzer automates the immunoassay reactions utilizing electrochemiluminescence (ECL). These reaction methods are described in detail in Chapter 4, ECL Technology. The individual test steps and how the system performs the necessary procedures are discussed here.
1.1.8.2 Test Protocols There are 28 test protocols or test steps that can be used on the analyzer. These protocols are predefined by Roche Diagnostics for each test and cannot be changed by the operator.
1.1.8.3 General Assay Sequence An immunological ECL test is made up of various pipetting steps, at least one incubation period and a measurement step. Generally at least three test components (sample, reagent and microparticles) are pipetted into an AssayCup. After the appropriate incubation period, the reaction mixture is aspirated into the measuring cell where the measurement process takes place. Each of the required pipetting cycles is performed within a defined period (42 seconds). The number of pipetting steps, as well as the make up of the reaction mixture are dependent on the test method (1 or 2 step test). For some methods, predilution with diluent and/or pretreatment with a special reagent is necessary. Thus the number of pipetting steps is increased. After each pipetting step the sample/reagent (S/R) probe tip is cleaned and, if necessary, the microparticle mixer and sipper probe are also cleaned. The following steps apply in principle to all methods. The sequence of the individual processes differ from test to test.
1.1.8.4 Preparative Operations Once the analyzer's power is switched ON, the initialization process is started. During initialization, the mechanisms are reset to their home positions.
1.1.8.5 Run Operation After the appropriate test selections are made in the software for patient samples, operation is started according to the predetermined test protocol for each assay selected. Initially, at least one reagent (R1 or R2) and the sample or microparticles (M) are aspirated one after another by the S/R probe. After each aspiration, the outside of the S/R probe tip is cleaned at the rinse station. The sample and reagents are dispensed into a new AssayCup and the AssayTip is ejected into the solid waste tray. For some tests that require sample dilution or pretreatment, diluent or pretreatment reagent is pipetted together with sample into an AssayCup. An aliquot of the diluted/pretreated sample is then dispensed with reagent into a second AssayCup. Therefore, certain tests with predilution/pretreatment may require two or more AssayCups.
1.1.8.6 First Incubation at 37 °C The incubation times are 4.5 or 9 minutes long, depending on the test. Some tests require only two incubation periods, whereas tests with pretreatment tests can require three incubation periods. During the incubation step(s) the immune complex products are formed.

Chapter 1.1
RD/Hitachi cobas e411
Service Manual
1.1.8.7 Additional Reagent Pipetting Some assays (usually those with multiple incubation steps) require additional reagent pipetting. As in the initial reagent pipetting step, a new pipette tip is picked up prior to reagent aspiration. The S/R probe tip is washed at the rinse station after each liquid aspiration. The liquid is then dispensed into the corresponding AssayCup where the sample and other liquids were dispensed in the first pipetting step. The probe rises while dispensing the reaction mixture back into the cup, thereby mixing the solution and accelerating the reaction in the cup. The pipette tip is ejected into the solid waste tray when pipetting is complete.
1.1.8.8 Second Incubation at 37 °C If necessary, a second incubation step (4.5 or 9 minutes) occurs. If using a pretreatment assay, the second incubation is similar to that described above for "First Incubation at 37 °C".
1.1.8.9 Additional Reagent Pipetting (Pretreatment assays) For pretreatment assays, reagent pipetting similar to that described above for “Additional Reagent Pipetting” occurs.
1.1.8.10 Third Incubation at 37 °C (Pretreatment assays) If necessary, a third incubation step (9 minutes) occurs for pretreatment assays.
1.1.8.11 Reaction Mixture Aspiration and Measurement In this process the sipper probe first aspirates ProCell (tripropylamine solution, TPA) to prepare the measuring cell. Then, the sipper probe aspirates the reaction mixture from the AssayCup and transfers it to the measuring cell. The sipper probe is washed at the rinse station and ProCell is aspirated again to rinse away the unbound reagent and sample constituents. Next, the ECL reaction in the measuring cell occurs.
1.1.8.12 Measuring Cell Cleaning Once the measurement is complete, the measuring cell is cleaned with CleanCell and prepared for a new measurement process. It takes 42 seconds (one pipetting cycle) from the aspiration of the reaction mixture by the sipper probe until the measuring cell is filled with ProCell and ready for the next sample.
1.1.8.13 Finalization 30 Minutes after documentation of the last result, the sipper pipettor flushes system water through the sipper probe, and then fills the measuring cell with ProCell before the analyzer returns to Stand-by. After this procedure periodically all 30 minutes the waste pump of the S/R rinse station is running for 2 seconds (waste consumption approx. 12 mL). This procedure will be stopped after you switch off the operation switch.

1.1.9 Detailed Assay Sequence The mechanical process of the instrument is described below using a sandwich test, TSH, as an example. This example assumes that the reagent pack was already registered by the analyzer and does not need calibration. All results are calculated based on an existing lot calibration.
1.1.9.1 Preoperation Steps When START (the Start Conditions screen) is pressed from Stand-by, the following preoperative steps occur. A. The analyzer resets all mechanisms to their respective home positions. Next, the S/R pipettor primes the S/R probe. B. The gripper checks for a tip in position number 1 of the tip trays. If this position is empty, the gripper remembers where it last left off and checks that position. If this position is empty, the gripper considers the whole tray empty and the System Overview screen is updated accordingly.
Note: If the analyzer is in S. Stop, the gripper remembers where it last left off and checks for a tip in that position.
1. During the tip check, the S/R probe is checked for the presence of a tip. The probe moves to the tip eject station and performs the movements to eject a tip. If a tip is present it is ejected. 2. After the tip check is complete, the AssayCups are checked in the same manner. During the cup check, the analyzer finishes priming the probes. 3. Next, the gripper checks the last three of the five positions on the pipetting station. If a cup is present, the analyzer goes through the steps of a cup disposal. The gripper places a tip in position 1 of the pipetting station. Then, the S/R probe picks up the tip in position 1 of the pipetting station. The S/R probe descends into the AssayCup and attempts to aspirate any possible liquid from the cup. The gripper picks up the cup and discards it into the cup disposal opening. As the cup is disposed, the S/R probe moves to the rinse station and dispenses any aspirated liquid. The tip is then washed and discarded. 4. The gripper moves to the incubator where it checks all 32 incubator positions. If a cup is present, the gripper moves the cup to position 5 on the pipetting station and uses the same procedure listed in step 3 to discard the cup. 5. The S/R probe tip is ejected after all the incubator positions are checked.

Dispense Reagent 1, Reagent 2 and Sample A TSH sample is present on position 1 of the sample disk. 1. After preoperation functions are complete, the gripper takes a tip from the tip tray and transports it to position 1 of the pipetting station. The gripper returns to its Stand-by position. 2. The sample disk rotates until position 1 is in the sampling position. 3. The S/R probe moves to position 1 of the pipetting station, descends to obtain the tip, rises and returns to its Stand-by position. 4. During this time, the reagent disk rotates until the TSH reagent pack is at the cap open/close mechanism. The mechanism moves forward and opens the caps on the reagent pack. The disk rotates again to move the TSH reagent to the R1 position. 5. The S/R probe moves from its Stand-by position to the R1 aspiration position. While activating liquid level detection, the probe descends until it is 2 mm below the reagent surface and aspirates 60 µL of R1. Version 1.0 – May 2006

Note: The lowest allowable point the S/R probe can descend to is 1.3 mm above the bottom of the reagent pack.
Figure 1.1-62 While aspirating R1, the gripper puts another tip in position 1 of the pipetting station. 6. If the S/R probe does not detect liquid during descent, no reagent aspiration can occur, an alarm is generated. 7. After R1 aspiration, the S/R probe rises and moves to the rinse station. To prevent the aspirated R1 from contacting the water in the rinse station, the probe aspirates 10 µL of air. The rinse station externally washes the tip. 8. During step 7, the reagent disk rotates until the TSH reagent pack is in the R2 position. 9. The S/R probe moves from the rinse station to the R2 position while aspirating another 10 µL of air. This air layer prevents R1 from mixing with R2. While activating liquid level detection, the probe descends until it is 2 mm below the reagent surface and aspirates 50 µL of R2. While aspirating R2 the gripper moves an AssayCup to position 5 of the pipetting station. 10. Upon completion of R2 aspiration, the S/R probe rises and moves to the rinse station. To prevent the aspirated R2 from contacting the water in the rinse station, the probe aspirates another 10 µL of air. The rinse station externally washes the tip. 11. After R2 aspiration, the reagent disk rotates until the TSH reagent pack is at the cap open/close mechanism. The mechanism moves out and closes the caps. 12. The S/R probe moves from the rinse station to the sampling position while aspirating another 10 µL of air. While activating liquid level detection, the probe descends until it is 2 mm below the sample surface and aspirates 50 µL of sample. During sample aspiration, clot detection is activated.

Note: Depending on the sample volumes and the type of vials used (e.g. primary sample tube or sample cup), the sample/reagent (S/R) probe can, when necessary, be lowered further to prevent air being aspirated. With some low capacity vials, the inside diameter is relatively small, which means the level of the liquid sinks when the liquid is being aspirated.
13. The S/R probe moves from the sampling position to position 5 of the pipetting station. The probe descends until the tip reaches 2 mm below where the calculated level of the reaction mixture surface should be and dispenses the sample, R2 and R1. The probe's downward displacement is determined by calculating the reaction mixture volume for the sample and utilizing downward displacement tables in the software. The probe does not rise during dispense. 14. After dispense, the S/R probe moves to the tip eject position and ejects the tip.

Dispense Reagent 1, Reagent 2 and Sample A TSH sample is present on position 1 of the sample rack. 1. After preoperation functions are complete, the gripper takes a tip from the tip tray and transports it to position 1 of the pipetting station. The gripper returns to its Stand-by position. 2. The pusher arm pushes the racks in the A-Line forward to the B-Line. The arm returns to its home position. The first rack loads on the B-Line. 3. As the rack incrementally moves on the B-Line, the rack bar code reader scans all five rack positions and rack ID. When scanning is complete, position 1 of the rack is in the sampling position. 4. The S/R probe moves to position 1 of the pipetting station, descends to obtain the tip, rises and returns to its Stand-by position. 5. During this time, the reagent disk rotates until the TSH reagent pack is at the cap open/close mechanism. The mechanism moves forward and opens the caps on the reagent pack. The disk rotates again to move the TSH reagent to the R1 position. 6. The S/R probe moves from its Stand-by position to the R1 aspiration position. While activating liquid level detection, the probe descends until it is 2 mm below the reagent surface and aspirates 60 µL of R1.

1.1.9.2 First Incubation 1. The gripper grasps and transports the cup containing the reaction mixture from the pipetting station to the incubator. 2. The cup is incubated at 37 °C for 9 minutes. 3. During incubation, the analyzer continues to perform operations for other test(s) or sample(s), if necessary.
1.1.9.3 Microparticle Preparation Before the first incubation is completed, the TSH microparticles are mixed to facilitate microparticle aspiration and dispense. 1. The reagent disk rotates until the TSH reagent pack is at the reagent cap open/close mechanism. The mechanism moves out and opens the cap. The disk moves the reagent pack to the mixing position. 2. The mixer moves over the reagent disk and descends into the microparticles to a level 1.4 mm above the bottom of the bottle.
Figure 1.1-69
Note: The mixer descends to this level regardless of the volume of microparticles in the bottle. 3. The mixer stirs the microparticles for approximately 4 seconds to obtain a homogeneous suspension. During the mixing, the gripper obtains a fresh AssayTip and transports it to position 2 of the pipetting station. 4. When mixing is complete, the mixer rises and returns to the rinse station where it descends and rotates in the rinse station for washing. 5. At the same time, the reagent disk rotates the TSH reagent pack to the microparticle pipetting position.
1.1.9.4 Microparticle Aspiration and Dispense 1. The gripper grasps the incubating cup and transports it to position 5 of the pipetting station. 2. The S/R probe moves to the pipetting station and obtains the fresh tip and moves to the microparticle pipetting position. 3. While activating the liquid level detection, the S/R probe descends to 2 mm below the reagent surface and aspirates 40 µL of microparticles. 4. After reagent aspiration, the S/R probe rises, moves to position 5 of the pipetting station and descends to dispense the microparticles. 5. After dispense, the S/R probe descends further until it is 0.8 mm above the bottom of the cup and aspirates the entire volume of reaction mixture. The probe rises while dispensing the reaction mixture back into the cup, thereby mixing the solution and accelerating the reaction in the cup. This mixing takes place only once.

1.1.9.6 Measurement Process Preparations Before the second incubation is completed, the sipper probe aspirates ProCell into the measuring cell to facilitate measurement. 1. The sipper probe moves from its home position to a ProCell bottle and descends to 2 mm below the solution level and aspirates ProCell into the measuring cell. During descent, liquid level detection is activated.
Note: The sipper probe can descend as low as 1.3 mm above the bottom of the ProCell bottle. 2. The sipper probe rises.
1.1.9.7 Measurement Process 1. The gripper grasps and transports the cup that has completed its second incubation from the incubator to the aspiration station. 2. The sipper probe moves to the aspiration station and descends into the cup until it is 0.8 mm above the cup bottom. This descent is independent of the reaction mixture volume. 3. When the sipper probe detects the reaction mixture in the cup, it aspirates 150 µL. 4. After aspiration, the sipper probe rises, aspirates 10 µL of air and moves to the sipper rinse station to descend for rinsing. 5. The gripper grasps the cup from the aspiration station, transports it to the cup disposal opening and discards the cup. 6. The sipper probe is rinsed. 7. The sipper probe rises and moves to the ProCell position, descends into the bottle and aspirates ProCell in a set aspiration/dispense sequence. The immune complex is captured by the magnet onto the electrode of the measuring cell. The ProCell washes away all unbound reagent and serum constituents. 8. After the bound-free separation, a voltage is applied between the working electrode and the counter electrode. The ECL reaction is initiated and measured by the photomultiplier. 9. After measurement, the sipper probe rises and moves to the CleanCell position and aspirates 20 µL of air. The probe then descends into the CleanCell bottle and aspirates reagent. This procedure is repeated eight times. The alternate flow of air and cleaning solution washes the measuring cell. During this washing process, a voltage is applied between the electrodes, which aids in the cleaning process. 10. The sipper probe moves to the sipper rinse station, aspirates 20 µL of air and descends into the rinse station for washing. 11. Finally, the sipper probe rises and moves to the ProCell bottle. The probe descends into the bottle and aspirates 500 µL of ProCell. Next, the probe aspirates 90 µL of ProCell and moves to the rinse station. At the rinse station, the probe dispenses 35 µL to flush the probe and prepare it for the next sample. During the aspirations of the ProCell, a sequence of voltages is applied three times to prepare the electrodes for the next measurement. One cycle of the measurement process consumes approximately 2 mL each of ProCell and CleanCell.

2.3.11 High Voltage Check/Adjustment Introduction Each MC in combination with a PMT represents a complete detection unit, which has to be adjusted correctly. The high voltage adjustment should be carried out after measuring cell preparation to obtain initial information about the instrument signal level. The high voltage value has been adjusted initially in the quality control department at Hitachi in the course of checks on the instrument, but not for some MC/PMT combinations. With the high voltage adjustment (check) the field engineer should make sure that the combination of instrument (photomultiplier tube, electronic components) and measuring cell work in the expected signal range. If the signal is not in the required range, the photomultiplier tube (PMT) voltage has to be adjusted to make the signal levels comparable between the different instruments. BlankCell reagent is used to check the signal level (refer also to Chapter 6, Assay performance explanation, for more details).
Note: The [PMT high voltage adjustment] run only checks the current signal level of instrument
Calibrator BlankCell reagent. The high voltage adjustment to the correct signal range then has to be carried out manually by the field engineer.

Calculate the mean value of the BCR2 effective signals from the Result screen. Note the target value from the package insert of the BlankCell lot used. Compare the mean value of the BCR2 counts with the target. It should be in the range of ± 5% of the target value.
Over time, the BCR2 level should be in the range of ± 10% (refer to Maintenance). •
If the current mean is outside the range, you may readjust the high voltage (refer to 2.3.11.5).
Note: We highly recommend that the high voltage is not changed in the first step if the signal level of the BCR2 mean is outside the range of ± 7% of the target value.
First of all, the measuring cell preparation should be extended by another 30 or 50 measuring cell preparation cycles (refer to Chapter 2.3.9). In the second step make sure that the measuring cell is mounted properly and that the BlankCell reagent is O.K. Refer also to Chapters Troubleshooting of Assay Performance Check

• •
Adjust the voltage between TP1 (GND) and TP2 (control voltage signal) by changing the resistance of the corresponding variable resistor (VR1, VR2 or VR3) according to the calculated control voltage. The resistor is chosen by the jumper setting of JP1 (Pos.1, 2 or 3; refer to Chapter 5.4.13 for details). If the new high voltage value is outside the selected range you have to change the setting of JP1then repeat the procedure, return to 2.3.11.2 If the new high voltage value is the O.K., change the PMT HV record (the label is on the PMT SHV cover).
Note: In case of problems make sure that LED1 located on the PMT-SHV2 PCB is lit. Check connection J400.

2.3.12 Initial BlankCell Calibrations Introduction After the measuring cell has been prepared and it has been checked that the signal level is in the expected signal range by means of the high voltage adjustment, the initial BlankCell calibration has to be performed. The instruments are calibrated to give the same homogeneous signal level. The initial BlankCell measurement is the first calibration done on the instrument before other assays can be calibrated. Each measured signal will first be BlankCell-corrected (parameters a (intercept) and b (slope)). The corresponding concentration is then read from the specific assay calibration. •

2.3.13 Instrument Checks Finally, we recommend that the Artificial Media Test and the TSH assay test are performed to check the instrument performance. To perform the runs you need the Elecsys check reagents.
2.3.13.1 Artificial Media Test (AM Test) Introduction The Artificial Media Test is a button in the menu [Assay Performance Check] in the [Utility] screen. It is a short instrument check and principally measures the same criteria as the RD internal instrument check. Homogeneous Determination With homogeneous determination magnetic separation is not used. A solution of free label is transported inside the measuring cell and the performance of the detection unit (MC/PMT) can be analyzed. With equal height of BCR2 1:20, the performance of the pipetter side can be analyzed. Heterogeneous Determination The heterogeneous determination simulates an assay. The iSAP test uses beads and a biotinylated and ruthenium-labeled antibody. An immuno-independent bead/antibody complex is generated to analyze the detection unit, measuring cell and magnet function. If all performance data for the homogenous determination are in order, then disturbance in the heterogeneous determination can only be caused by the liquid flow system (tubing/fittings, connectors, sipper),the magnet or the MC BCR1, BCR2 and BCR2 1:20 are homogeneous, ProCell, iSAP and TSH are heterogeneous. The test takes about 45 min. Table 2.3-5 Materials Required RackPack name BlankCell CellCheck SAP

Evaluation of the AM Test The instrument can automatically calculate the results. Press the [Print result] button in the [Assay performance] screen. To evaluate the results use the parameters and acceptable ranges for the artificial media test given in the table. (For target values refer to table Table 2.3-13 “APC test; Targets, AM test”). If troubleshooting is necessary refer to the charts given in 2.3.13.3.
Note: If a result is missing, the mean and CV are calculated wrongly. In such cases calculate the corresponding result manually with the formulas given in Calculation Formulas
•
The BCR (BlankCell reagent) target value should be reached; this is used for the instrument calibration. The determination of BCR1 means the lower, BCR2 the higher calibration value. This reflects the recovery and the variance of the target value.
Note: None of the measured counts with tests from the Assay Performance Checks are connected with the instrument calibration factor.
• • • • •
BCR2 is used to adjust the PMT-HV and indicates problems with the PMT and excitation. BCR2-D is a dilution of BCR2 with BCR1 and shows the functionality of the pipetter, the pipetter precision and general problems with the liquid handling. AB3(CO) is determined using the measuring cycle for heterogeneous assays. These values are the basic values used for calculating carryover. iSAP is a model assay based on streptavidin beads. iSAP facilitates the evaluation of the complete LFS (liquid flow, magnet, capturing, detection) in a routine assay. Carryover is the measurable influence on the assay performance and is the consequence of carryover of beads into the measuring cell in this case.

BCR2 target value, concentration values for TSH Cal1and Cal2, and LO factor (LOF) are provided for each lot by RD. LOF is defined as ratio: (tangent new rackpack lot) / (tangent frozen reference lot) That factor is corrected by the typical coefficient of reagent aging on a monthly base. That typical coefficient of reagent aging is calculated as the median monthly decay over several lots. LOF and its aging forecast are transferred from RD. Table 2.3-12 Please Enter a Table Caption

2.3.13.2 TSH Assay Test TSH assay (heterogeneous determination) is a button in the menu [assay performance check]. Unlike to the artificial media test, the customer as a matter of routine performs this immunoassay. The TSH assay is a necessary service tool as it reveals problems in the assay performance that occur in determinations where high dynamic, very low LDL (lower detection limit) and very high precision are required. For instrument/instrument performance criteria we have to use more detailed checks. There, the calibration also plays a role. The test takes about 45 min.

2.3.13.3 Evaluation of the TSH Assay Test The instrument can automatically calculate the results. Press the [Print result] button in the [Assay performance check] screen. To evaluate the results use the parameters and acceptable ranges for the TSH assay test given in Table 2.3-21 on the next page (APC tests; Targets, TSH test) If troubleshooting is necessary refer to the charts in 2.3.13.3.
Note: If a result is missing, the mean and CV are calculated wrongly. In such cases calculate the
corresponding result manually using the formulas given in Test items performed by the TSH assay test
The tangent (TSH Cal2) describes concentration-independent dynamics. A tangent value outside target indicates problems with the measuring cell, LFS and MC or the magnet. The LDL (lower detection limit) is the lowest value that differs significantly from the concentration of 0 µU/ml. Dynamics and precision in the lower range influence the LDL. Apart from problems with the measuring cell, the pipetter or the magnet, problems with the sipper, liquid handling and liquid flow ( tubing, foam, bubbles ) and temperature influences increase the LDL, i.e. give poorer assay performance. An increased first value of the TSH Cal1 (TSH Cal1 1st value high) is seen in the event of a preceding homogeneous determination (e.g. ProCell, Prepare, Idle). In most cases it is related to the performance of the measuring cell. A high first value is only observed if a ProCell/Prepare cycle is run before a very low signal in a heterogeneous determination.

3.1 Description of Flow Path • • • •
• •
System water is supplied by the water supply bottle (capacity: 3.5 liters) and the water level is monitored by a float switch. Water is pumped by a magnet pump and distributed to the pipetter and sipper inside/outside wash and also to the mixing paddle wash via a branch pipe and the solenoid valves (SV). The pipetter line has clot detection (Refer to Chapter 5.3.4 for principle of clot detection), and checks for blood clots and serum gel separator clots, etc. Reacted solution is sipped into the measuring cell in the detection unit by means of the sipper probe; waste is transferred to the waste solution bottle after measuring. All system water that is used for washing (P) & (S) probes and paddle is collected in the waste solution bottle via the cleaning path (P), & (S). The waste bottle has a capacity of 4 liters. A mechanical switching unit detects whether the bottle is full and causes the instrument to go into sampling stop. System water quality requires less than 10µS/cm conductivity. If water conductivity is higher, liquid level detection fails will occur because the detection method relies on a capacitance principle. Refer to the overall piping diagram for details of the flow path.

3.2 System Volume Introduction The system volume value is needed by the system to ensure that the sample is transported to the measuring cell working electrode surface. If the system volume is wrong the results may vary. (Bad CV´s )
Note: Whenever a part on the sipper line (excluding the measuring cell ) is exchanged the system volume has to be determined.
3.2.1 Definition of System Volume The volume between the sipper needle top and the measuring cell outlet. The mean system volume of the e411 is 460 µl ± 30 µl. The measuring cell itself has a volume of 60 µl ± 5 µl.
3.2.2 Determination of System Volume Preparation Place 1 (one) set of system reagent ProCell/CleanCell bottles filled with ProCell/CleanCell at Position 1, right side in the system reagent container.
3.2.2.1 Procedure ► ► ► ► ► ►
Make sure that the instrument is in standby status. Touch the [Utility] button. Touch the [Maintenance] button. Touch the [Service] button. Touch the [System Volume Check] button and Touch the [Select] button. Touch the START button in the screen.
The system volume is determined as follows: The sipper line is first filled with ProCell. An air bubble of 100 µl is set. The air bubble is transported to the measuring cell. Before the bubble arrives at the cell the measuring cell voltage is switched on. The bubble separates the reference electrode (RE) from the counter electrode (CE) and working electrode (WE). When the bubble leaves the cell a current peak is created, and this peak is measured to calculate the volume (refer to Figure 3.2-1 and Figure 3.2-2).
Note: After the procedure has been finished successfully the instrument returns to Standby. If an
error message appears, refer to troubleshooting. The system volume value is not displayed.

3.3 Cleaning Procedures Introduction Two cleaning procedures are recommended for the e411 flowpath. Liquid flow cleaning (see Chapter 3.3.1) This cleaning procedure is also part of the customer maintenance (see Operator’s Manual) and should be carried out frequently. Service liquid flow cleaning (equivalent to 3 customer cleanings) should only be performed in the event of high grade contamination problems (e.g. heat pipe blockage) Cleaning for Fluidics System (see Chapter 3.3.2) This procedure cleans tubings and the washing stations, but not the sipper line.
3.3.1 Liquid Flow Cleaning
Introduction Contamination in the sipper system could potentially degrade sample accuracy and precision, or possibly block the measuring cell flow path. Liquid flow cleaning keeps the sipper liquid flow path clean and maintains the integrity of the measuring cell. The customer should perform LFC on a frequent basis. Please train all your customers according to the procedure described below and inform them about the importance of keeping the liquid flow path clean and the measuring cell at the best performance level. If operators perform this procedure frequently it will lead to fewer customer complaints. Required materials:
SysClean adapter Ident. SysClean Solution Recommended frequency*: ∗
No.: 1933159.910 Ident. No.: 1298500 Every two weeks or after 2500 - 3000 cycles
If customer maintenance has been done as recommended, it is only necessary to carry out an additional customer cleaning at the PM visit. The service LFC is only necessary during PM if the sipper line is highly contaminated or if LFC has not been carried out regularly by the customer.
Operator time: Analyzer time:
Approx. 3 minutes User LFC: Approx. 16 minutes (user) Service LFC: Approx. 32 min + time for MC prepare cycles The cleaning solution is corrosive. Wear protective gloves and glasses when handling this solution.
Precautions:

Insert the adapter with the marking "USER" in direction towards the back of the instrument. Fill the SysClean solution to the edge of the fill mark on the adapter (approx. 9 ml). PC/CC bottle has to be placed at the left side. Same procedure as for customers but using the Service position of the adapter. Touch the Liquid Flow Cleaning button on the screen (Screen: Util / Maintenance). The number of LFCs should be 1 for User maintenance. The number of LFCs should be 3 for service. Take out the SysClean adapter and place ProCell and CleanCell bottles in all positions. Perform Measuring Cell Preparation cycles. [Press ”MC Preparation” in Maintenance screen; select number of cycles]
Start the LFC procedure shortly after filling up the SysClean solution. After the instrument returns to Stand by remove the SysClean adapter and discard the remaining ISE solution. To avoid an unpleasant odor, please empty the waste container at the end of the liquid flow cleaning procedure. After a Service LFC has been performed customers should check all controls and carry out a calibration if necessary. This is not necessary for normal routine with customer LFC.
3.3.2 Cleaning Procedure for Fluidics System The fluidics system consists of the tubing system, the pipettor, all wash stations except the part between the sipper probe and SV3) The cleaning procedure is a function to be carried out when frequent high water conductivity errors happen and if the system is contaminated with bacteria, algae, etc. Contamination can lead to problems with the pipetting or washing processes, thereby degrading the sample accuracy and precision.
Note: This is not a part of the routine maintenance for the e411. This procedure should only be used if contamination has occurred.
3.3.2.1 Required materials - 30 % Perhydrol-Solution; Fa. Merck Cat. No.: 1.07209.1000
Procedure 1 ►
Remove the system water container. Fill with 3% Perhydrol solution and empty the liquid waste container.(Put about 100 ml 30 % Perhydrol solution in the tank, and fill up with purified water to the 3 L mark. (3.5L volume). Mix carefully. Replace the system water container.
2 ►

Repeat points 5 to 7 twice to guarantee that the whole system is filled with system water.
9 ►
After finishing, the top of the screen changes to Stand-by. Please empty the liquid waste container and refill the system water container with system water. The system is now ready for the normal routine.
In case of frequent high water conductivity errors, check that the pipettor LLD voltage is 1.5 V or lower. Otherwise, repeat the cleaning process with system water until the voltage is reduced to 1.5 V. In case of strong contamination repeat the whole cleaning procedure again.
Note: There are some instruments that generate the alarm "Distilled Water: 25-01-01" during Cleaning and the status shifts to Stand-by. However there is no problem with the performance of cleaning function if enough system liquid (around 3 L) has run.

3.4 SysWash 3.4.1 Introduction SysWash is used as an additive to the wash water in the e411. SysWash increases the rinsing efficiency between pipetting steps. SysWash also contains a preservative to protect the system from contamination (e.g. by bacteria). The detergent solution is particularly necessary when performing analyses using e411 infectious disease assays, but can also be used for the other parameters. Before SysWash is regularly used on the instrument, service has to carry out the Rinsing procedure (see below). After the rinsing procedure has been finished, SysWash has to be used in the system water in the recommended concentration (prepared working solution contains 0.075% detergent).
Note: The SysWash is recommended for use in all e411 systems. For further details refer to “Product Information” inside the SysWash package. SysWash Cat No. 1930346 1 x 500mL
3.4.2 SysWash Rinsing Procedure 1 ► 1.1 ►
Preparing the Mixture in the System Water Container Take 35 mL of SysWash and pour it into the empty e411 wash water container. Fill the container with distilled water to the highest mark (dilution ratio is now 1 + 100).
Note: When pouring in the water make sure that it flows quickly enough, but avoid the formation of foam. This ensures that the additive will be dispersed evenly in the wash water, so no additional mixing will be necessary.
2 ► 2.1 ►
2.2 ►
Analyzer Rinsing Procedure Proceed as follows to ensure that the active component is present in the tip wash station for the first determination: Start CLEANING-function ([Util] [Maintenance] [Service Cleaning] [Start]) Run the CLEANING-function 2-3 times. Make sure that the total rinse volume is ≥ 5 L *.*This amount is necessary to replace the volume in the buffer container below the system water container.

Service Manual
Stirrer Head Vertical Movement Mechanism The Stirrer Head Vertical Movement Mechanism moves the stirring paddle up and down over the RackPack with its cap open and over the wash bath. The stirrer head that supports the stirring paddle and the vertical movement mechanism are vertically connected with an arm pipe. A nut holder and slide guide that are installed on the inner and outer rings of the ball bearings are installed in the vertical movement mechanism. A spline nut is inserted in the nut holder. The slide guide and the nut holder shift up and down guided by the spline shaft and guide shaft; the slide guide stops the rotation and the vertical movement, and the nut holder controls the rotation triggered by the rotation of the spline shaft and makes vertical movement. Pulleys are positioned above and below the moving parts keeping a sufficient axle distance from the stirring paddle so that they will not contact with each other when the stirring paddle makes strokes. The slide guide, which is hooked up to the timing belt, is moved vertically, driven by the stepping motor. Slow down rate

Stirrer Head Rotating Mechanism A nut holder is fixed on the inner ring of the ball bearings and a slide guide on the outer ring. An arm pipe that secures the stirrer head is fixed to the nut holder. The ball bearings guide the arm pipe and nut holder to swing together within a range limited by the stopper that is installed on the slide guide. Driven by the stepping motor, the moving parts cause rotation of the pulley that is attached to the bottom of the spline shaft. The rotating force is conveyed to the pulley via the timing belt.

4.4.5 Pipetter Mechanism 4.4.5.1 Overview The pipetter mechanism is a mechanism that picks up disposable tips and pipettes sample, calibrator, reagent (beads, R1, R2 and diluent, etc.) into the reaction vessel by means of an X-Z moving mechanism.
4.4.5.2 Location See Chapter 4.2.
4.4.5.3 Functional Details The pipetter mechanism consists of the following components: •
X-Axis movement mechanism
•
Z-Axis movement mechanism
•
Tip/Vessel buffer
•
Pressure (clot) sensor
X-Axis Movement Mechanism The X-axis movement mechanism moves the pipetter probe to each sampling position and replaces the disposable tip. The X-axis movement mechanism drives Z-axis mechanism that is mounted on the timing belt with a stepping motor.
Z-Axis Movement Mechanism The Z-axis movement mechanism moves the pipetter probe and disposable tip to each sampling height position, and drives the nozzle head that is mounted on the timing belt with a stepping motor via the LM guide.
Tip/Vessel Buffer •
The tip/vessel buffer is the area where the gripper places the disposable tips and the reaction vessels so that the pipetter probe has access to them.
•
There are sensors in the first two positions to detect the presence of a tip; the gripper mechanism also checks the tip and vessel placement
•
The tip eject position is at the edge of tip/vessel buffer.
Pressure (Clot) Sensor This detects clots in sample, calibrator, reagent or diluent during piping by monitoring pressure changes inside the tube.

4.4.6.3 Detailed Function This unit consists of the following components: •
Base frame
•
Y carriage
•
X carriage
•
Grip part
•
Container station
•
Incubator station
Base Frame Base frame is fixed on the four (4) pillars that are secured to the main base. The carrier mechanisms such as the Y carriage, container station, and incubator station, are attached to the base frame.
Y Carriage The Y carriage contains the X carriage (mentioned below). It is driven in the Y direction (back and forth movement) and placed (at 0.25 mm/step) via the stepping motor and the pulley belt mechanism. The Y carriage is supported by the following bearings: •
On the right side: Two (2) linear bearings that are guided by a shaft
•
On the left side: One (1) radial bearing that is guided by the channel
A shielding plate on the right of the Y carriage passes via three (3) photo interrupters fixed on the base frame and detects home position, rest position, and end position (the order starts from the front).
X Carriage The X carriage contains the grip parts described below. It is driven in the X direction (left and right movement) and placed (at 0.125 mm/step) via the stepping motor and the pulley belt mechanism. A shielding plate on right of the X carriage passes via 3 photo interrupters on the right side of the Y Carriage and detects home position.
Grip Part The grip part consists of the Z-driving part and the grip-driving part. The grip-driving part consists of a rack gear driven in the Z direction (up and down shift) and placed (at 0.2 mm/step) via the stepping motor and the Z-drive part of the rack/pinion mechanism. The grip-drive part is Version 1.0 – May 2006

supported by a linear guide fixed to the X carriage and is pulled up via a spring. A shielding plate secured on the upper side of the grip-drive part passes via 3 photo interrupters at the upper side of the X carriage and detects home position. The grip-drive part is driven to open/close via a cam rotated by a rotary solenoid and a pair of arms with a grip nail positioned to catch the cam. The tip/vessel is gripped at the nail by the power of pull-spring attached to close a pair of arms and is positioned on X & Y where the back arm is pushed by the cam. A shielding plate located at the tip of the front arm passes via Photo Interrupter under the condition w/o tip/vessel and detects “None.” Also, a pair of arms are supported and guided to up and down shift as well as holder which retains the arms above and below and positioned to the lower edge by two (2) push-springs. If Grip-drive part is lowered to abnormal positions on XY, the head part of tip/vessel halts the down movement of a grip nail, arms, and a holder. A shielding plate located at the bottom side of Grip-drive part passes via Photo Interrupter secured to the holder and detects “Abnormal Down Position.”
Container Station The container station has a partition to hold three (3) tip containers and three (3) vessel containers and is positioned at the base frame via two (2) pins located at the bottom side and secured by four (4) screws.
Incubator Station Incubator Station consists of the heat block with thirty-two (32) storage holes for vessel incubation with one (1) vessel storage hole sipping, heater, and thermistor. It is secured to the base frame by two (2) screws.

Base Frame The base frame is fixed on the platform that is secured on the top part of the main unit base. The X carriage and Z carriage are installed on the base frame.
X Carriage The X carriage contains the Z carriage, which is explained below. The X carriage shifts horizontally at a speed of 0.3 mm/step to its position, and is driven by the stepping motor and pulley / belt mechanism. At its top, the X carriage is held up by two linear bearings that are supported by the shaft, and at the bottom the X carriage is supported by two radial bearings. There are two photo interrupters on the base frame. The home position sensor is on the right and the end position sensor is on the left (as viewed from the front of the cobas e411). The X carriage stops in six positions: CC2, AB2, CC1, AB1, Washing Pos., and Sipping Pos. in a normal operation.
Z Carriage The Z carriage shifts vertically at a speed of 0.1 mm/step (during the aspiration of the reaction agent at 0.025 mm/step) to its position, and is driven by the stepping motor and the pulley / belt mechanism. The Z carriage is supported by the linear guide that is installed on the X carriage. The shielding plate that is installed on the right side of the Z carriage passes the photo interrupter above the top of the X carriage and detects the home position. The probe inside the Z carriage is moved vertically and is positioned to the bottom end by a spring. If the Z carriage descends from an abnormal position, the mechanism interrupts the descent of the probe and the shielding plate interrupts the beam from the photo interrupter that is installed on the Z carriage. This leads to an error, “Abnormal Descending.”

4.4.8 System Reagent Mechanism 4.4.8.1 Overview The system reagent mechanism is a unit that keeps the liquid temperature constant inside the AB and CC bottles. The case of the system reagent mechanism has grooves for an AB bottle and a CC bottle. By setting an AB bottle and a CC bottle, one at a time, it adjusts the case temperature by means of a Peltier temperature controller.
4.4.8.2 Location See Chapter 4.2.
4.4.8.3 Functional Details The System Reagent Mechanism consists of the following components: •
Bottle Heating Unit
•
Case Heating Unit
•
Thermostat
Bottle Heating Unit The bottle heating unit is a die-cast product made of flat aluminum (5mm thick). Its function is to keep the liquid temperature inside the AB and CC bottles at 28
C. This aluminum case detects
the signals from the sipper probe when the sipper probe detects the liquid level in the bottle, and is therefore insulated from other parts and the main unit base.
Case Heating Unit Insulating material is attached to the bottom and sides of the aluminum case and, in addition, the case is enclosed in a steel case frame so that the bottles inside the case are not be subject to the ambient temperature. In order to secure the thermostat, the case frame is installed on the main unit base and is fixed to the cooling unit holder. The case frame is also used as a holder for the sipper probe wash bath.
Thermostat A Peltier element thermostat is installed on the outside bottom of the aluminum case. A thermistor is installed in the space between the case surface and the side of the case. It measures the difference between the ambient temperature and the case temperature, and the thermostat regulates the case temperature.

4.4.11 Liquid Waste Container Mechanism 4.4.11.1 Overview The liquid waste container consists of the following two units. It collects wash liquid and reaction waste. 1. Liquid waste container (capacity: 4 liters) 2. Container station (capacity: 3.5 liters, with fill level detector; also detects whether or not the container is installed.)
4.4.11.2 Location See Chapter 4.2.
4.4.11.3 Functional Details The liquid waste container consists of the following components: •
Liquid waste container
•
Container station
Liquid Waste Container The liquid waste container has a handle and a cap on its upper part. Remove the cap and position the liquid waste container in the specified position.
Container Station The container is located in the inner station of the container station. The inner station is attached to the outer station that is installed in the main unit base and is pushed up by a shaft on the back and by a spring in the front. A shielding plate is installed in the inner station. This shielding plate is depressed as the waste liquid level increases. When it is depressed, it passes the beam from the photo interrupter installed in the outer station and thus indicates when the waste liquid container is full. A pressure plate with a shaft and coil spring is attached to the front of the inner station. This pressure plate is installed so that it pushes in the container. A shielding plate is installed on one end of the pressure plate. If a container is not installed, the pressure plate will cause the photo interrupter beam to come through the shielding plate and the “no container” state is detected.

4.6.4.2 Overview of Operation This line accurately conveys the rack that has the samples that have been received from the A line to the bar code reading position and the pipetting position. After reading the sample bar code and the rack bar code and after pipetting, the rack is conveyed to the C line (storage unit) or the D line.
4.6.4.3 Rack Feeding Operation 1. The rack is conveyed when the following requirements are fulfilled during the operation: •
When the Rack Detection (PI212:dark) or the STAT SW is inputted. However, when there is a detection at the same time, the Rack Detection(PI212) is given priority.
2. The rack is conveyed when the following requirements are fulfilled during reset: • •
• •
Home removal is done when Home Detection (PI210: dark) is on When Home Detection (PI210: dark) remains on, if there is SW recognition it remains in standby after moving to STAT rack position (Interrupt half as a result of STAT Detection (PI213:dark by H.P).If there is no recognition of the STAT SW, Rack Feeding is done when the C line and the D line are in a condition to carry. After that, it returns to home and then goes into standby. If Home Detection (PI210: dark) is not attached; it goes into standby after returning to home. If Home Detection (PI210: dark) is not attached, Rack Feeding is done when the C line and the D line are in a condition to convey. After that, it returns to home and then goes into standby. The rack prior to reading the bar code should not be a reset rack.
3. The rack is conveyed to the pipetting position when the following requirements are fulfilled. When the Rack Full Detection (PI223) for the C line buffer is on and when the rack detection for the rotation mechanism (PI241, P1244) is on, a series of analyses is continued and after the final sample pipetting of the rack that has been loaded, and until the above detections are canceled, it will be in a standby mode in that position.
4.6.4.4 Explanation of Operation 1. In the Home position, it will interrupt and stop when Home is detected (PI260: dark). 2. The bar code reading position detection will interrupt and stop the movement of the bar code reading position (PI216: dark). The same is true for the movement between samples but from the 5th sample to the bar code position shall be a fixed pulse feed. 3. The Sampling Position Detection (PI215: dark → bright) will interrupt and stop the movement from the bar code reading position to the pipetting position. Also, the Sampling Position Detection (PI215: dark → bright) shall interrupt and stop the movement between the samples. Skip processing shall be done for samples that have no analysis requests and if there are empty positions. For empty racks, one machine cycle shall be used to process. 4. the Rack Feed End Detection (PI211: dark) will interrupt and stop the movement from the 5th position to the storage position. 5. By pressing the STAT SW after placing the rack in the STAT rack position, the STAT rack processing makes the machine recognize that there is a STAT rack. The STAT detection (P1211) from H.P will interrupt and stop the movement to the STAT rack position. If the STAT SW is pressed, it will give priority from the rack feed of the A-Line after analysis of all of the samples in the rack that are currently being processed and will convey the STAT rack.

For regular rack feeding, interrupt stop by the rack feed end detection (PI222 detection: dark) from H.P. (1 rack shall be fed to the tray.) Returns to Home Position after feeding. However, at the end of feeding, when both the Rack Full detection 1 and Rack Full detection 2 (PI296 detection: dark) has entered, a ‘Warning’ alarm goes off. Also, after that, until the Rack Full detection (PI296 detection: dark) goes in, it continues a 1 pitch feed. 3. When both the Tray Full detections are resolved, all of the racks that are in the buffer are fed to a batch of trays. (feeds a maximum of 5) 4. When both the Tray Full detection and the Rack Full detection (PI223 detection: dark) both go in, a ‘Warning’ alarm goes off. 5. After that, when both the Tray Full detections have been cleared, analysis automatically starts up again. 6. When returning to Home after 1 rack is fed, (1 pitch feed) a check on the remaining pulse is done and checks whether the 1 rack feeding is being performed normally or not. 7. When the Rack Full detection (PI223: dark) for the Buffer is on, rack feeding of the A line is not done.

5.3 Electronic Modules / Electronic Adjustments 5.3.1 Principle of Temperature Control The temperature control is performed by the microprocessor ANGCNT on the EECL300 board. Temperature is controlled by four units by one of the following two methods.
5.3.1.1 Incubator, System Reagent Unit The unit calculates the control signal using the deviation between the target temperature given by the CPU and the actual temperature measured at the control point and outputs the signal on the DO3 board. The signal is augmented on the DO3 board, and the system runs electricity to the Peltier or the heater. The fan is used to maximize the heat release efficiency. As the voltage applied to the Peltier increases, the fan turns on. No fan is used in the incubator.
Figure 5.3-1 Temperature Control Block Diagram (Incubator, System Reagent)
5.3.1.2 Reagent Disk, Detection Unit The reagent disk determines the target temperature from the ambient temperature of the reagent disk unit. The detection unit determines the target temperature from the ambient temperature of the system reagent unit. The system calculates the control signal using the deviation between the target temperature and the actual temperature measured at the control point and outputs the signal to the DO3 board. The DO3 board augments the signal and the system runs the electricity to the Peltier or the heater. The fan is used to maximize the heat release efficiency and turns on as the voltage applied to the Peltier increases.

5.3.2 Principle of LLD • •
•
The liquid level detector of the cobas e411 detects the change of the static electricity capacity between the detection electrode and GND before and after its contact with the liquid. The structure of the liquid level detector is shown in Figure 5.3-3. The detection electrodes used for the pipetter are a nozzle tip and a disposable tip made of a conductive material. The sample disk and reagent disk are also made of a conductive material and are grounded. The detection electrode used for the sipper is the system reagent unit, and is grounded via the sipper nozzle. The outer wall of the system reagent unit is shielded. When the CPU sends a command to the GPCNT (motor controller) to lower the pipetter (or the sipper), it also sends a command to the LLD CNT (liquid level detection controller) to start the liquid level detection. Upon receiving the start command, LLD CNT starts monitoring the signal output from the LLD-P3 board (or the LLD-SA board for the sipper). LLD CNT processes the received signal and when the signal is for the liquid surface, it sends a "motor stop" command to GPCNT. The output and "motor stop" signals from the LLD-P3 board (or the LLD-SA) are described in Figure 5.3-4 (Figure 5.3-5for the LLD-SA).

5.3.3 Principle of Clot Detection • • •
Clot detection is a monitoring function of liquid pressure in the pipetter tube when sampling to detect abnormal situations as a result of a blood clot, fibrin, etc. Liquid pressure is detected by a semiconductor pressure sensor and a half bridge circuit on ANGEP2 PCB, and this signal is also amplified on ANG-EP2 PCB. Then, the pressure signal (range 0 5 volts) is converted to a digital signal by EECL PCB and sent to ECPU 550 PCB. The clot detection algorithm is fixed by software parameters in the Data FD.
5.3.4 Adjustment / Check Procedure of LLD/Clot Detection This describes an adjustment procedure if the following items are replaced or checked. • • •

1 ► 2 ►
Ensure that the pipetter tube is primed Use a plastic screwdriver to adjust the variable capacitor on the LLD-P3 PCB as shown in Figure 5.3-12. When monitoring the voltage, keep your hands off the pipetter arm.
After “Reset”, select “Voltage Monitor” and execute “Pipetter LLD”. Adjust the voltage to the minimum value while the pipetter head is at the highest position. ► The voltage without tip has to be below 1.5V (see Figure 5.3-9 for testing position) and the principle LLD curve (check pos. 1) should be in the recommended range (see also Figure 5.3-8).
3 ►
Put a tip onto the pipetter nozzle. ► The voltage with tip should be increased by 0.1 V to 1.5 V (check pos. 2, see Figure 5.3-8). If the voltage decreases, re-adjust the trimmer so that the voltage increases with a tip.
4 ► 5 ► 6 ► 7 ►
Take out the RackPack from positions 1, 17 and 18 on reagent disk. Move the pipetter to reagent position 18 by hand. The pipetter should be in the position of R2 aspiration (see Figure 5.3-10) Move the pipetter down to position “A” by hand, see Figure 5.3-10 and Figure 5.3-11 for detailed position. The tip should not touch any plastic. Memorize the monitoring voltage. Move the pipetter down to position “B” by hand, see Figure 5.3-10. ► Make sure that the monitoring voltage increases between 0.3 V and 0.7 V (see Figure 5.3-8).

Adjustment of Pipetter Z Abnormal Detection range Check the crash sensor signal output by measuring the voltage between the connector pin#A3 of J552 and TP2 (AG) on DIST-PA Board as follows. • •
Detach the Pipetter head cover as shown in Figure 5.3-7. Make sure that the voltage is 0.5 V or lower (ca.35 mV) under normal conditions, i.e. no crash is detected.
Note: Keep the current height of the pipetter head. This means that only pipetter probe itself should go up and down during the next measurements.
• • • • •
Make sure that the voltage is 0.5 V or lower (ca.35 mV) when the thickness tool (0.8), which is 0.8 mm in thickness, is inserted into the gap between the pipetter probe and the flat place as shown in Figure 5.3-7. Also make sure that the voltage increases up to ca.4.5 V or more (ca.5V) when the tool is replaced by the 1.2mm thickness tool under the same conditions. If the increase is not sufficient, bend the detection plate on the pipetter probe upwards or downwards with pliers (see Figure 5.3-13). Repeat the above procedure until the specification is met. Replace the pipetter head cover as before.

1. It stops before it reaches the liquid surface. 2. It does not stop at the liquid surface, but goes deep in the liquid. 3. It starts descending from an incorrect position.
Pipetter Abnormality of the liquid level detection for the pipetter may be caused by one of the following problems. Use the following procedures for troubleshooting. •
•
The insulation resistance of the probe is low. ο Detach the two (2) wires from the probe. ο Measure the insulation resistance with a voltage multimeter or any similar device. ο If the resistance is normal, the resistance goes up beyond the measurable limit of the multimeter. ο If the resistance is low, it will be shown by a value below 1,000 kΩ. In this case replace the pipetter probe. The electrical conductivity of the water inside the pipetter tube is too high. ο Measure the output voltage of the LLD-P3 board twice as follows. a) With the tubing located inside of the pipetter head connected. b) With the tubing disconnected. ο
•
• • •
If there is a difference in the output voltage between the former and the latter, the conductivity of the water could be increased. ο With the tube connected, move the pipetter horizontally and check the voltage. If the output voltage varies depending on where the pipetter is located on the horizontal axis, the conductivity of the water could be increased. ο If high conductivity is detected, replace the water in the water supply tank by water with conductivity meeting the specification. Repeat the pipetter prime to clean the flow path. The spring of the pipetter nozzle holder is mispositioned. ο If the spring of the pipetter nozzle holder, which is installed in the upper cover of the pipetter case, is mispositioned, the inner pipe (detection electrode) and the outer pipe (shield) of the pipetter become mutually conductive. In such a case, the voltage output from the LLD-P3 board goes up by ca. 10 V. ο If the output voltage is normal when the cover is open, but it is not when the cover is closed, mispositioning of the spring may be the cause. In this case, return the spring to the normal position. The board is damaged due to liquid leakage. The liquid level is too low or there is no liquid in the container. Damaged wiring and damaged FPC will cause abnormal liquid level detection with the pipetter.
Sipper Abnormality of the liquid level detector for the sipper may be caused by one of the following problems. •
The insulation resistance of the system reagent unit is low.

5.3.6 Details of Temperature Control / Troubleshooting of Temp. Units 5.3.6.1 Principle of temperature control • •
Temperature control is based on PI control. ANG CNT determines the control parameter for the peltier or heater by calculating every 100 ms as follows. It first calculates the difference (En) between the current temperature of the control point (Tn), which is the temperature n ∗100ms after temperature control started, and the target temperature (Ttrg).
(a) En = Tn - Ttrg •
It then sums up Ens to the Esumn .
(b) Esumn = En + Esum(n-1) •
Finally, it determines the control parameter (Vout).
(c) Vout = K1*(K2*En + K3*Esumn) (K1, K2 and K3 are coefficients) • •
The voltage of the incubator is limited from 0 V to 5 V, the voltages of other unit are limited within ±5 V. The temperature of the reagent disk and the detection unit is influenced by the ambient temperature around the units. So the target temperatures (Ttrg) for the two units are calculated according to the formula below. The Ttrg of the R.Disk refers to the temperature around the reagent disk, and the Ttrg of the detection unit refers to the temperature around the system reagent unit.
Ttrg = A*Tamb + B (A and B are control coefficients) Table 5.3-2 Coefficients of Temperature Control

Note: The Peltier works as a heater when the control parameter is positive and as a cooler when the control parameter is negative.
Note: The control parameters (Vout) are multiplied by +1 at the EIO3 board and by -2.6 at the DO3 board. Voltages are limited within ± 12 V on the DO3 board.
Note: The control parameter for the detection unit turns over when it comes to ANGCNT.On the
Temperature Monitor Screen you can see the voltage which does not turn over. It turns over by the cable (P/N 741-4237) between the DO3 board and the detection unit
5.3.6.2 Troubleshooting •
If temperature below 4.6 degrees C is displayed
1. If temperature control is being normally operated, the temperature displayed in the screen should be 13 to 15 degree C at the lowest. 2. Therefore, if the screen displays a temperature below 4.6 degrees C, this may be due to the thermistor wire or the cable between the EECL300 board and the thermistor breaking. 3. What is displayed is identical to that which is displayed if the thermistor resistance were infinite. •
If temperature higher than 80.0 degrees C is displayed
1. If temperature control is normal, the thermostat breaks the input for peltier or heater at around 60 degrees C. 2. Therefore if the temperature is displayed higher than 80.0 degrees C, this may be due to the thermistor or the cable between the EECL300 board and the thermistor being shortcircuited. 3. This phenomenon is identical to that which takes place if the resistance of the thermistor were zero (0) ohm. •
If temperature does not meet the specification
1. Check whether covers the are closed or not. For example, temperature control of the R. Disk does not work well without the R. Disk cover. 2. Check that there was not a steep temperature gradient. The specification of the temperature gradient is ± 2 degrees C /h. Direct wind from air conditioners, etc., must be avoided. 3. Check the relation between the indication temperature and the ambient temperature of the thermistor. 1) Check the peltier or the heater if the two temperatures are nearly the same. 2) Check the thermistor if the two temperatures are significantly different.

Because of the thermometer accuracy might be within ± 0.5 degrees C, only a rough comparison is possible. •
How to check the peltier and heater. 1. Check the resistance between the wires of the peltier or heater to detect any abnormalities in the element. 2.

How to check the thermistor
1. Check the resistance between the wirings of the thermistor to determine whether or not the thermistor is normal. 2. Thermistor errors are usually caused by moisture. 3. With the usual ambient humidity, the thermistor never absorbs moisture. However, if the thermistor gets wet as a result of condensation, the resistance of the thermistor goes down significantly. Therefore, there are no circumstances in which the thermistor only slightly defective, and so the error is quick to find. 4. Table 5.3-4 shows the check pins of the thermistor. 5. Table 5.3-5 Table 5.3.6-4 shows the outline of the resistances of thermistor. 6. Details are shown in the data sheet for the thermistor. Table 5.3-4 Check pins for thermistor Unit

6.2.1 Detailed Description of Each Maintenance Function 6.2.1.1 System Reset System Reset is a maintenance function that resets all the mechanical units and primes the pipetter system. This function is to be carried out when an operation is aborted due to an error and takes all the mechanical units to their original positions. The reset function in the Service software is identical to the reset that is carried out at the beginning of each run. Only Start and Close are available in the System Reset pop-up window. About 20 ml water are needed each time System Reset is carried out.
6.2.1.2 Liquid Flow Cleaning Contamination in the sipper system could potentially degrade sample accuracy and precision, or possibly block the measuring cell flowpath. Liquid flow cleaning keeps the sipper liquid flowpath clean and maintains the integrity of the measuring cell. The customer should perform LFC on a frequent basis. Please train all your customers according to the procedure described below and inform them about the importance of keeping the liquid flow path clean and the measuring cell at the best performance level. If operators perform this procedure frequently it will lead to fewer customer complaints. Required materials: Recommended frequency *: ∗
SysClean adapter Ident. No.: 1933159.910 ISE Cleaning Solution Ident. No.: 1298500 Every two weeks or after 2500 - 3000 cycles
If customer maintenance has been done as recommended, it is only necessary to carry out an additional customer cleaning at the PM visit. The service LFC is only necessary during PM if the sipper line is highly contaminated or if LFC has not been carried out regularly by the customer.
Operator time: Analyzer time:
Approx. 3 minutes User LFC: Approx. 16 minutes (user), Service LFC: Approx. 32 min + time for MC prepare cycles The cleaning solution is corrosive. Wear protective gloves and glasses when handling this solution.

The number of LFCs should be 3 for service. Take out the SysClean adapter and place ProCell and CleanCell bottles in all positions. Perform Measuring Cell Preparation cycles. [Press ”MC Preparation” in Maintenance screen; select number of cycles]
Start the LFC procedure shortly after filling up the ISE solution. After the instrument returns to Stand by remove the SysClean adapter and discard the remaining ISE solution. To avoid an unpleasant odor, please empty the waste container at the end of the liquid flow cleaning procedure. After a Service LFC has been performed customers should check all controls and carry out a calibration if necessary. This is not necessary for normal routine with customer LFC.
When Liquid Flow Cleaning is completed the Liquid Flow system is set in the usual condition in which the system is set when a run is completed in the normal manner. The function takes about quarter of an hour.
6.2.1.3 L.And A. Reset All* ∗
*This function is available only for Rack Sampler.
L&A All Reset is a maintenance function that carries racks whose barcode has already been read to the unloader, resets all the mechanical units and primes the pipetter system. This function is to be carried out when an operation is aborted due to an error to take all the mechanical units in the original position and the operation should be restarted from the condition before the error occurred. The reset function in the Service software is identical to the reset which is carried out at the beginning of each run. About 20 ml water are needed to carry out the Reset function once.
6.2.1.4 Rack Clear* ∗
*This function is available only for Rack Sampler.
Rack Clear is a maintenance function that carries all racks in the line to the output line (C line). Only Start and Close are available in the reset pop-up window.
6.2.1.5 Sipper Pipetter Prime Sipper Pipetter Prime is a maintenance function that primes the sipper system with system water. This function is to be carried out when the tubing in the sipper system is drained due for reason such as replacing the tubing. However, this function should not be carried out unless it is followed by measuring cell preparation. This is because the measuring cell is filled with water after the Sipper Prime, and this might cause the luminescence signal to drift at the beginning of the following run. In addition to Start and Close buttons in the pop-up window, the iteration number can be set in the input area. The maximum iteration number is 100. It takes ca. 10 s to carry out the Sipper Prime function once, and the process consumes ca. 5 ml water.
6.2.1.6 S/R Pipetter Prime S/R Pipetter Prime is a maintenance function that primes the pipetter system with system water. This function is to be carried out when the tubing in the pipetter system is drained for some reason such as replacing the tubing, although the Pipetter Prime is always carried out when the system is reset or a run is started. In addition to Start and Close buttons in the pop-up, the iteration number can be set in the input area. The maximum iteration number is 100. It takes ca. 11 s to carry out the Pipetter Prime function once, and the process consumes ca. 6 ml water.

6.2.1.7 Measuring Cell Exchange Measuring Cell Exchange is a maintenance function that primes the sipper system three times and drains the measuring cell. This ftunction is to be carried out before you replace or take out the measuring cell mounted in the detection unit. Only Start and Close buttons are available in the pop-up window. About 15 ml water are needed to carry out the Measuring Cell Exchange function once
6.2.1.8 Measuring Cell Preparation Measuring Cell Preparation is a maintenance function that carries out preparation cycles in order to condition a newly mounted measuring cell or measuring cells which have undergone maintenance (refer to Installation and Maintenance). In addition, this function can be used just to initialize the sipper system, especially just after the sipper prime to fill the MC with assay buffer. In addition to Start and Close buttons in the pop-up window, the iteration number of the preparation cycles can be set in the input area. The maximum iteration number is 100. Place ProCell and CleanCell bottles in system reagent position 1 when you start this function. The consumption of water and system reagents to carry out Measuring Cell Preparation are as follows: Water: 150ml + iteration number × 5 ml System reagents: iteration number × 2 ml The following functions are to be carried out sequentially when Measuring Cell Preparation is started. 1. 2. 3. 4. 5. 6. 7.
Reset Priming the sipper system between the sipper syringe and the waste via SV4 (ca. 20 s) Checking the system reagent inventory Preparation 1 cycle (once without potential application) Preparation 2 cycles according to the iteration number with the potential application Preparation 3 cycle (once with the potential application) Sipper finalization
When Measuring Cell Preparation is completed the sipper system is set in the usual condition in which the system is set when a run is completed in the normal manner.
6.2.1.9 Finalization Maintenance The Finalization Maintenance initiates the daily maintenance procedure of finalization maintenance. Finalization is the analyzer status that occurs between the time when the analyzer stops pipetting samples (S. Stop or R. Stop) and Stand-by. Finalization allows the analyzer to stand unused for several hours (e.g. overnight). The system is primed with water, the measuring cell is filled with ProCell and the sipper probe is cleaned with water. The function takes about three (3) minutes.

6.4.7 Initial Blank Cell 6.4.7.1 Introduction After the measuring cell has been prepared and it has been checked that the signal level is in the expected signal range by means of the high voltage adjustment, the initial BlankCell calibration has to be performed. The instruments are calibrated to give the same homogeneous signal level. The initial BlankCell measurement is the first calibration done on the instrument before other assays can be calibrated. Each measured signal will first be BlankCell-corrected (parameters a (intercept) and b (slope)). The corresponding concentration is then read from the specific assay calibration. For further details refer to Chapter 2.3.12. 1 ►
Set to “ON” on BlankSet Option.

► ► ► ►
Start Reagent Scan (Reagent Screen ) After the scan the BLANK CELL is requested by the instrument. Press the Start button. After the Blank Cell procedure has finished, check the printout of the results carefully. The quality criteria should look the same as in the specimen printout. See attached printout of successful Initial Blank Cell (specimen).

It is very important that the Initial Blank Cell is successful. If not, repeat the process until it is successful, otherwise all results may not be corrected properly. Refer to Chapter 2.3.12.3 for current result targets. (If necessary start procedure once more. Go back to point 3.) If the Initial Blank Cell was successful, remove the BLANK CELL RackPack. This is very important, otherwise the instrument will do the periodic blank cell automatically. Start reagent scan.
6.4.7.2 Evaluation of Initial BlankCell • • •
Compare the mean value of the BCR1 (all values are on the printout) counts with the target. It should be: BCR1 Target range 120 to 400 counts. Check the slope value from [Initial BlankCell] screen: BCR2 Slope should be 1.0 ± 0.05 (= parameter (b)). If one of the targets is outside these limits refer to the recommendations given and repeat the procedure until the targets are reached.
6.4.7.3 Further Explanation of the Results Printed Out Headline messages and interpretations two messages are possible: •
BlankCell calibration was generated. This message means that the procedure was successful; all quality criteria were met. No need for further action.
•
BlankCell calibration can’t be generated.

This means that the procedure failed; one or more of the quality criteria failed. The detailed quality messages and the data groups below have to be studied to determine the cause.
Quality messages and interpretations Three messages are possible, each depending on the results of the quality checks with status ok / not ok. In case of Öok no further action is needed. In case of any Önot ok the following interpretations are possible: Missing values This field displays six dashes representing the six single measurements of the procedure. In case of problems the data are not complete. The instrument was not able to perform the six measurements. If a number appears instead of a dash, there was a problem with this measurement, and this may indicate a mechanical problem.Problems with missing values cause further messages as achievement of targets and deviations of replicates Önot ok. Deviation of replicate measurements This field reads Öok if the replicate measurements are within the replicate limits listed in the columns below. Ö In case of any Önot ok a new BlankCell request has to be set and a new initial BlankCell has to be performed : Achievement of targets This field reads Ö ok if all values of the replicate measurements are within the corresponding ranges Lower and Upper around the targets. If the field reads Ö not ok, it indicates abnormal signal levels. It is possible that only one single measurement has failed. In this case the means seem to be Öok but the achievement of targets and probably the deviation of replicates are Önot ok. Comparison to last valid BlankCell This quality message was only designed for user´s periodical BlankCell. Therefore, it is ignored in case of the Initial BlankCell.
Data groups and interpretations mean target lower

The lower acceptable limit in PMT counts. The limit was formerly designed as the limit for a working range for the user’s periodical BlankCell. For initial BlankCell it detects only extreme problems (< 200 counts for BCR1 / - 7% for BCR2). A better criterion for signal levels are parameters a and b in the screen (-79 for a, 0.93 for b). The upper acceptable limit in PMT counts. The limit was formerly designed as the limit for a working range for the user’s periodical BlankCell.

Description Adjustment finished successfully. Corresponds to alarm code 51_01_02. The Gripper could pick up a Tip or Cup at the adjustment limit of the adjustment position(s) that is (are) used to calculate the adjustment value. Therefore, there is the possibility that the automatic adjustment was not finished successfully. Corresponds to alarm code 51_01_01. The Gripper could not pick up a Tip or Cup at the adjustment position(s) that is (are) used to calculate the adjustment value on at least one occasion. Therefore, the automatic adjustment failed.
Note: If the displayed color is red, the adjustment value does not change. However, if the
adjustment values for X and Y are displayed in the same display window, one of the adjustment values may be overwritten because the adjustment values for X and Y are calculated separately.
