Roche Diagnostics Service manual · Version 2.0 April 2007 A-7 1 Safety information 91xx pH/Electrolyte Analyzers ESD protection measures ESD protection measures ESD = Electrostatic Sensitive Device Explanation of the phenomenon The most frequent cause of electrostatic discharge is friction of various materials such as plastic, synthetic fiber, hard rubber or paper. It can also be caused by bending or applying pressure to a material. Discharges that are dangerous to components occur when "charged" bodies or components do not have a discharge connection (ground) to discharge the electrostatic charge. The discharges normally do not have a high capacity, but there are often voltage differences in the range of several thousand volts. The discharges are perceived as small shocks or visible sparks. Examples: o Shoes with rubber soles: Friction is caused by walking. A person develops an electrical charge different from the ground. A discharge occurs when an object (e.g. door handle) is contacted. o Synthetic fiber clothing: Discharge is audible and is visible in darkness. The dryer the air the greater the risk of electrical discharge caused by friction. Eectrostatic charges are less likely to build up in humid air, particularly when saturated with water vapor. The probability of ESD phenomena is therefore particularly great in a northern hemisphere winter in centrally heated rooms where the humidity is low. Influence of electrostatic charges on components If a person with an electrostatic charge touches a component, a discharge over a connection of an IC or semiconductor element may occur. The resulting voltages may damage the component. Critical situations can occur while repairing or testing components if they are lying on a more or less conductive surface (e.g. table top) and a person with an electrostatic charge touches them. A discharge through a critical component connection can also occur in this case. Roche Diagnostics A-8 April 2007 Service manual · Version 2.0 91xx pH/Electrolyte Analyzers 1 Safety information ESD protection measures Why is ESD protection so important today? Formerly, current controlling semiconductors were mostly used (TTL, normal transistors, etc.). Today the principle of current logic is virtually the only technology in use in MOS and CMOS components. Currents generated by an electrostatic discharge (as much as several kV!) destroy the sensitive component inputs or cause hidden damage. This damage is generally not immediately detectable. Another effect is that the clearances inside the ICs continuously become smaller. The internal wires become thinner and thinner, the allowable maximum input voltages become smaller and the effects of any discharges become more and more critical. How can ESD protection be guaranteed? A continuous discharge is required when working on an electronic assembly. Do this as follows: o Use ESD wrist bands (special wrist bands connected to a protective ground). o Repairs and tests on assemblies must only be conducted on tables with ESD mats connected to grounds or ESD wrist bands. o Always pick up components at the edge (e.g. like a photo). o Components must always be transported in ESD packages or appropriate storage or shipping containers (use original packaging!). o Shoes with rubber soles or clothing of synthetic fibers must not be worn in workshops where electronic components are repaired. o Use a humidifier if necessary to maintain optimum humidity in the work area. o Do not touch assemblies or components with the hand after testing. o Always transport and ship assemblies or components for repair in ESD protective packaging only. This will prevent further damage that may result in misinterpretation of the original cause of the fault. The ESD mat consists of materials that have a very low, defined conductivity (1012 ohms). The following materials prevent charges caused by friction from building up and protect the component from damage. o ESD mats o ESD packages o Shipping containers Conclusion Of course, not all circuit boards and electronic assemblies require such careful handling. An electrical board that only carries simple plug connectors does not require ESD packaging. In cases of doubt always use ESD packaging.

Roche Diagnostics A-26 April 2007 Service manual · Version 2.0 91xx pH/Electrolyte Analyzers 4 Description of modules Description of modules Lamp board The rear panel and SBC board must be removed to gain access to the lamp board. Remove one screw and washer which hold the board in place and remove the electrical connectors to remove this board. Display board The rear panel and SBC board must be removed to gain access to the display board. Remove three screws and 50 degree spacers and unplug the preheater or sample sensor cable from the front and the ribbon cable to the SBC board to remove the display board. Fluidic Module Standard A Standard A is drawn to the electrode module by vacuum provided by the peristaltic pump. 9110 pH Analyzers: When Standard A is to be aspirated into the electrode module, solenoid valve A and R are opened. Standard A is then drawn from the ISE SnapPakTM until Sample Contact 1 detects Standard A bridging the T-piece and Sample Contact 1. At this point, solenoid valve V is opened and solenoid valve A is closed. The standard is pumped up the tubing, through the wash portand into the sample needle until Sample Contact 2 detects the standard. The peristaltic pump slows down and the standard moves into the electrode module until detected by Sample Contact 3 (bridge between sample preheater tube and reference electrode). Then, the pump stops. 9120, 30, 40, 80, 81 Electrolyte Analyzers: When Standard A is to be aspirated into the electrode module, solenoid valve A is opened and solenoid valves B, V and R are closed. Standard A is then drawn from the ISE SnapPakTM, to the fill port, through the sample needle and is sensed by the sample sensor. At this point, solenoid valve V is opened and solenoid valve A is closed as the peristaltic pump continues to pump Standard A into the electrode module. As the trailing edge of the Standard A sample is sensed by the sample sensor, the peristaltic pump stops. During the time Standard A is aspirated into the electrode module, the reference housing is pressurized due to the peristaltic pump providing pressure to the reference solution line and solenoid valve R being closed. An amount of reference solution is forced out through the reference junction to provide contact to the sample. Standard B The process for Standard B is identical to that of Standard A with the exception of the operation of solenoid valve B. This solenoid valve is operated in reverse order of Standard A aspiration. Standard C (not on 9110) The process for Standard C is identical to that of Standard A with the exception of the operation of solenoid valve C. This solenoid valve is operated in reverse order of Standard A aspiration. Roche Diagnostics Service manual · Version 2.0 April 2007 A-27 4 Description of modules 91xx pH/Electrolyte Analyzers Description of modules Cleaning solution (9110 only) The cleaning routine within the 9110 pH Analyzer is automatic with cleaning solution being aspirated through the system every 40th sample or every 24 hours. Automatic operator-initiated cleaning can also be performed, by selecting ELECTRODE CLEANING from the main menu. The cleaning routine is very similar to the aspiration of Standard A or B with solenoid valve C being opened to allow cleaning solution to be aspirated through the fluidic path. The timing of the cleaning solution routine allows for a larger volume of cleaning solution to be aspirated than the Standard A or B cycles to ensure that cleaning solution covers the electrodes, wash port, fill port, sample needle and preheater during the cleaning cycle. Reference solution The reference housing is filled automatically using the second winding of the peristaltic pump and solenoid valve R. The reference solution connector allows for the reference housing tubing to be plugged into the reference solution circuit. As the peristaltic pump aspirates reference solution, solenoid valve R is opened to allow excess solution to be pumped into the reference return line of the ISE SnapPakTM. A check valve is placed in the return line to ensure that the KCl output is constant (9110 only). Waste liquids Calibration standard and sample waste are pumped out of the left side of the electrode module (green-banded tubing) through the peristaltic pump to the waste line of the ISE SnapPakTM. An internal one-way valve is incorporated into the waste line of each ISE SnapPakTM to prevent any waste products from leaking out of the ISE SnapPakTM. Main tube set (all models)/ Intake tube set (9110 only) The main tube set is supplied as a pre-cut tubing harness with the fluidic interconnections preassembled. Replacement of the tube set should be performed annually. For removal of the tubing, first remove the ISE SnapPakTM from the reagent compartment. This will allow access for removal of the white TPR block which is the main interconnection between the ISE SnapPakTM and the tubing. This block can be removed by grasping the front surface and pulling forward. Next, remove tubing from each solenoid valve. Follow the procedure outlined in Section 4.1.5 for disassembly of the solenoid valves to enable fluidic tubing to be easily removed at each solenoid. e For details, see Rear panel assembly on page A-25, SBC board on page A-26. Pull the two pump windings at the peristaltic pump tube set off the pump roller and remove the white reference solution tube connector. Remove the white TPR reference solution block by grasping the front of the block and pulling forward. The three tube connections are labeled with green, blue and red tags. All remaining tubes can now be removed and the entire tubing harness can be discarded. Fit the replacement tubing harness and assemble in reverse order as disassembly. Reference the Tube Diagram on the next page for correct tube locations. Intake Tube Set (9110 only) Roche Diagnostics A-28 The intake tube set comprises three pieces of tubing. A short piece (red tag) fits between the white T-piece and the standard contact. The long piece can be positioned between the standard contact and the wash port. The remaining tube can be fitted between the sample needle and the preheater tube.

Test points are provided to measure supply voltages, and light emitting diodes D1 through D5 are turned on to indicate each supply voltage present on the card. Since each LED is connected in series after the fuse, a blown fuse results in the respective LED turned off. Four additional voltage regulator circuits are mounted on the ISE SBC II Card. IC U2 and IC U3 provide -8 VDC and +8 VDC (9180/9181: -5 VDC and +5 VDC) and are used to provide the supply voltages for the analog circuitry. IC U1 develops the supply voltage used to operate the peristaltic pump and provide either +10 VDC or +22 VDC. The +22 VDC is supplied only for the FAST speed and +10 VDC is used for all other pump speeds. Signal FAST/SLOW determines which supply voltage is selected. U5 switches the voltage between 22 VDC and 12.5 VDC (16 VDC on the 9110) which supplies the solenoids. When a solenoid is turned on, the voltage switches to 22 VDC for 0.5 sec, then it returns to 12.5 VDC (16 VDC on the 9110). The circuit which includes Q7 and R5 provides necessary switching for the measuring chamber illuminator LEDs. The following list identifies the test points, fuses and LEDs for each respective DC supply voltage: Test point Voltage Fuse Rating LED TP1 +24 VDC F3 1.25 AT D3 TP2 +5 VDC F1/F2 2.0 AT/1.6 AT D1/D2 TP3 -12 VDC F4 0.3 AT D4 TP4 +12 VDC F5 0.3 AT D5 TP5 Ground Table A-5 Test point Voltage TP6 -8 VDC (9180/9181: -5 VDC) TP7 +22/12 VDC TP8 +8 VDC (9180/9181: +5 VDC) TP9 Na+ channel (pH channel on the 9110) TP10 K+ channel (not used on the 9110) TP11 Ca2+/Cl– channel (Li+ 9180/9181 only; not used on the 9110) TP12 Temperature TP13 +10.000 V ref. voltage TP14 -2.500 V ref.voltage (-2.500 V on the 9110) TP15 Sample sensor (sample contact voltage on the 9110) TP16 +22/12.5 VDC (+22/+16 VDC on the 9110) Table A-6 Roche Diagnostics Service manual · Version 2.0 Voltage test points, LEDs Voltage test points April 2007 A-33 4 Description of modules 91xx pH/Electrolyte Analyzers Description of modules Valve drivers Pump motor driver/cover sensor The solenoids are activated by transistors Q9 - Q13. To open the solenoid, a 0.5second pulse of 22 V is applied, then the voltage drops down to 12.5 V (16 V on the 9110) to hold the solenoid open. The pump driver circuit IC U9 and IC U10 provide the drive and control for the peristaltic pump. Signals PUMPEN, Pump Enable and PUMPSTEP, Pump Step Pulses enable IC U10 to provide the necessary control to driver IC U9 which supplies pump drive signals PHASE A through PHASE D to control peristaltic pump operation. IC U11 operates with signal DCLOSED from the sample door light gate to provide signal DOOR which detects the status of the sample door (open or closed). Input amplifiers IC U13, U14 and U15 (9110/9180/9181: U13 only) provide high to low input impedance matching for each Electrode input. Offset generator IC U12D and amplifiers IC U12A, U12B and U12C provide the necessary gain and offset for each electrode channel. TP9, TP10 and TP11 provide test points for the Na+ (TP9: pH on the 9110), K+ and Cl–/Ca2+/Li+ channels respectively. 9110 only: IC U300 is used as the input amplifier for the reference electrode, IC U12A is used for the subtraction of the reference electrode signal from the pH electrode signal. For sample detection, the reference electrode is switched to ground (relay K300) during aspiration. Temperature sensor This circuit is used in the 9110 pH Analyzer to amplify the signal of the temperature sensor in the preheater. This is an optional circuit which is used in the 9140, 9180 and 9181. The circuit creates a temperature-dependent voltage which is converted by software to degrees Celsius. R54 can be adjusted for correct temperature display. Analog channel selector and A/D converter Analog inputs from the input amplifiers are selected via signals ADSEL0 through ADSEL2 and are multiplexed by IC U19. This multiplexed signal is then fed to the A/ D Converter IC U20. IC U21 supplies the necessary reference voltage (2500mV) for the A/D Converter and can be measured at TP14. Microprocessor Microprocessor IC U31, EPROM IC U25 (9180/9181: U40) and MOSTEK Real Time Clock/RAM IC U22 form the components of the central processing system. IC U23 Address Demultiplexer, IC U24 Programmable Array Logic (PAL) and IC U28 provide serial data buses (9180/9181: U23, U24 and U28 not present). IC U34 through IC U38 convert serial data to parallel data and provide printer data, display data, solenoid valve control and peristaltic pump control (9110: U34 not present). This fashion of serial to parallel data conversion is used to prevent analyzer lock-up by peripheral devices. The RS232 serial interface is a direct input/output from the microprocessor utilizing interface driver and receiver U29 and U30. SnapPak Sensor (9180/9181 only) Optical detector ISO1 provides a signal indicating if the ISE SnapPak™ is in place. This signal is fed to U41 which converts the light gate input to a digital logic output indicating SnapPak position (IN or OUT). Lamp board The lamp board contains the LED array used to illuminate the measuring chamber and the interconnectors used for all solenoids, the peristaltic pump, door sensor and sample turntable (9181 only). A ribbon cable from the SBC Board supplies the electrical connection for each signal through connector JP6. Roche Diagnostics A-34 April 2007 Service manual · Version 2.0 91xx pH/Electrolyte Analyzers 4 Description of modules Description of modules Display board The display board contains the LCD display, sample contact circuit (9110 only) or sample sensor connector, the preheater (9110 only) and the YES and NO switches used for operation of the analyzer. Power and signal interconnection is accomplished via a ribbon cable from the SBC board through JP2 on the display board. 9110 only The sample contact circuit consists of a square wave generator U1B which generates a 500 Hz signal. U1A amplifies the signal, D2 and C3 rectify the square wave. The gain can be adjusted with R10. The sample contact output provides a DC voltage, which is proportional to the square wave amplitude. During sample aspiration, the preheater tube and the sample contact 1 tube are connected to the square wave via relay K1. The heater control circuit controls two transistors which are placed in the preheater block. A thermistor provides temperature feedback to the setting of potentiometer R20. The signal difference drives the base of the heating transistors via buffer U2C. U2D shuts the system off in case the thermistor opens. U2B limits the maximum heating current during warm-up. U1C and attached circuit is used as an AC/DC converter to create negative voltage -VSS, using square wave generator U1B. 9181 only Roche Diagnostics Service manual · Version 2.0 Display boards utilized in the 9181 analyzer also contain circuitry for both the needle mechanism motor control and position sensor. The autosampler "Table Present" signal is also buffered through U1 on this board.

STATUS: NOT CALIBRATED This message is only displayed when a calibration has been interrupted by pressing NO or opening the sample door. Perform a calibration to return to the [READY] Mode. STANDARD A NOT DETECTED This message is displayed when sample contact 1 (9110 only) or the sample sensor is unable to properly detect the Standard A solution in a programmed time period. As the analyzer draws a sample of Standard A, the leading edge of the solution is detected by sample contact 1 (by bridging solution between both parts of sample contact 1) or the sample sensor. The sample sensor must also detect a continuous flow of Standard A Solution into the sample chamber, lasting several seconds, without encountering air bubbles or air. After several seconds, the trailing edge of the Roche Diagnostics Service manual · Version 2.0 April 2007 D-5 13 Troubleshooting 91xx pH/Electrolyte Analyzers Error messages and troubleshooting Standard A sample is sensed, the peristaltic pump stops and measurement occurs. If aspiration fails, the analyzer will wash and repeat up to 3 times. Possible causes and remedies o Check for air leaks preventing the Standard from being drawn into the chamber. Ensure that all O-rings are in place. There must be a continuous draw of standard solution, free of air bubbles. o Check solenoid V for proper sealing of the vent line. o Check fill port to ensure the absence of air leaks. o Verify that the sample needle is not bent. o Check/replace fill port and wash port to ensure the absence of air leaks (9110 only). o Check for clots or crystals formed in the Standard A tubing or electrode chamber. o Replace peristaltic pump tube set to ensure proper sample aspiration. o Ensure that the preheater cable (9110 only) or the sample sensor is plugged in securely and perform h [TEST SAMPLE CONTACTS] or h [TEST SAMPLE SENSOR] to ensure correct operation. Clean, adjust or replace sample sensor to correct sample sensor operation. o Check the fluid remaining in the ISE SnapPakTM. If less than 5% remains, replace the ISE SnapPakTM. STANDARD B NOT DETECTED, STANDARD C NOT DETECTED (9180/9181 only) The system for drawing Standard B or C is like that of Standard A. If Standard A is drawn properly and Standard B or C is not detected, check Standard B tubing for crystallization. Perform checks for Standard A detection problems to correct. During the calibration sequence, Standard B or C is drawn into the measuring chamber prior to Standard A, therefore check if Standard A calibrant can be properly detected to isolate possible fluidic faults. If neither Standard A, B nor C are detected check for air leaks or blockages within the fluidic path. CHECK SAMPLE CONTACTS(9110), CHECK SAMPLE SENSOR (9120/30/40/80/ 81) The sample contacts must provide a reading of 135 - 145 when air is detected and the sample sensor must provide a reading of 80 - 120 when air is detected. Perform h [TEST SAMPLE CONTACTS] or h [TEST SAMPLE SENSOR] to observe sample contact or sample sensor response. When clear fluid (e.g. water) is aspirated, the sample sensor display must indicate an increase of of at least 40 units. For blood samples (not transparent), the reading should decrease by at least 40 units. The sample contacts can be adjusted (see cross reference below), the sample sensor is calibrated with air during each calibration. e For details, see Sample contacts adjustment (9110 only) on page C-5. Perform a calibration to remove the error message after troubleshooting. Roche Diagnostics D-6 April 2007 Service manual · Version 2.0 91xx pH/Electrolyte Analyzers 13 Troubleshooting Error messages and troubleshooting Possible causes and remedies 9110 o Check for correct drying of measuring chamber during the wash cycle. o Replace peristaltic pump tube set. o Check for clots and leaks in the sample path, especially in the fill port area. o Clean the sample contacts using Electrode Cleaning procedure. o Test and adjust sample contacts to correct adjustment. o Replace sample contacts as needed. Note Sample contacts can be tested by invoking [TEST SAMPLE CONTACTS] within [SERVICE FUNCTIONS]. If reading is low, disconnect each sample contact and notice a change in the displayed result to isolate a specific contact fault. 9120/30/40/80/81 o Clean sample sensor using Daily Cleaning procedure. o Test and adjust sample sensor to correct adjustment. o Replace sample sensor assembly. CHECK REFERENCE HOUSING At the beginning of a calibration, pressure is formed in the reference housing while the R valve is closed and the V valve is open. After Standard A is detected in the sample chamber, the back pressure formed in the reference housing causes the Standard A solution to move back toward the preheater (9110) or the sample sensor. When the standard A solution is detected by the preheater (9110) or the sample sensor, the R valve is opened to release the pressure. If the preheater (9110) or the sample sensor does not detect standard A as it moves back, [CHECK REFERENCE HOUSING] will be displayed. Possible causes and remedies o Check for clogged reference housing and clean per monthly maintenance procedures. o Check and ensure that reference tubing is securely connected at the tubing connector. o Check for proper filling of the reference housing and ensure that reference solution reagent level allows complete filling of the reference housing. o Check for bubble-free aspiration of Standard A. PLEASE CLOSE SAMPLE DOOR (except 9181) This message occurs and prints [NO SAMPLE] on the print-out, when either of two conditions exists. Roche Diagnostics Service manual · Version 2.0 o Sample door is not closed within 20 seconds after samples are in place. o Sample door has been opened and no sample is detected within 20 seconds.

NO SAMPLE This message is displayed when any of the following conditions occur: o During sampling, either a bubble in the sample is detected or the sample size is smaller than the minimum sample required. o The sample door is opened and no sample is fed into the analyzer. o Sample door is not closed within 20 seconds after sample is detected. o Check whether the sample sensor is plugged in and perform h [TEST SAMPLE CONTACTS] or h [TEST SAMPLE SENSOR] to verify that it operates correctly. o Check sample draw and look for clots or leaks in the sampling system. Possible causes and remedies CLEANING FLUID NOT DETECTED When the cleaning cycle has been initiated, the analyzer checks for proper aspiration of the cleaning solution using the sample contacts (9110) or the sample sensor. If solution is not detected in the proper time, above error message will be displayed. Possible causes and remedies o Ensure that a sufficient volume of cleaning solution is presented for aspiration and no air bubbles are present as solution is aspirated. o Check to ensure that the solution is being aspirated through the sampling mechanism correctly. The sample path must be free of leaks or clots. o Verify that sample sensor is properly plugged in and perform h [TEST SAMPLE CONTACTS] or h [TEST SAMPLE SENSOR] to verify the correct operation of the sample sensor. o Check pump tubing and replace as necessary to ensure a correct pump rate. CONDITIONING FLUID NOT DETECTED (except 9110) When the conditioning cycle has been initiated, the analyzer checks for proper aspiration of the conditioning solution using the sample sensor. If the solution is not detected in the proper time, this error message will be displayed. Possible causes and remedies o Roche Diagnostics D-8 Ensure that a sufficient volume of conditioning solution is presented for aspiration and no air bubbles are present as solution is aspirated.
