ESD protection measures
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.
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.
ESD = Electrostatic Sensitive Device
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.

Service manual · Version 2.0 A-9
91xx pH/Electrolyte Analyzers 1 Safety informationESD 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.
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.
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

Solenoid assembly
Removal of each solenoid is identical. Each solenoid valve has a removable pressure piece which is held in place by a solenoid cap. To remove the pressure piece, locate the arrow on the solenoid cap and remove the solenoid cap by sliding it off the solenoid shaft in the direction of the arrow. This exposes the pressure piece which can now be removed from the solenoid shaft. To replace pressure piece and cap, energize the solenoid as described in TEST PINCH VALVES on page B-67. This extends the solenoid shaft to the outermost position for ease in replacing pressure piece and cap. Removal of the pressure piece and cap is required prior to removing the solenoid and allows for easier replacement of the tubing under each solenoid.
To remove the solenoid assembly, the rear panel and the SBC Board (described in Rear panel assembly on page A-25 and SBC board on page A-26) must be removed first.
e For details, see Rear panel assembly on page A-25, SBC board on page A-26.
Each solenoid has an electrical connection to the lamp board which must be unplugged prior to removal of the solenoid. At this point, remove the two screws on the front panel to remove the solenoid assembly.
Printer assembly
The printer assembly is designed to allow for easy removal by the user which can be accomplished without removal of the electrical power to the analyzer. Slide the paper tray forward to allow access to the printer, tear the paper roll and completely remove it together with the paper tray. Slide fingers under the printer assembly and pull the printer forward. This will disengage the printer from the interconnector and enable removal of the assembly from the front of the analyzer. Removal of the printer should be performed for replacement and for removal of a paper jam.
To replace the printer, locate the printer slide and insert the printer assembly. Press firmly into place to ensure electrical connection of the printer.
Rear panel assembly
To remove the rear panel assembly, ensure that the power cord has been disconnected from the analyzer. Remove the four corner screws to expose the rear panel.

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 ElectrolyteAnalyzers:
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.

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.

Electronics
ISE SBC card
Power circuits Power is supplied to this circuit board through connector JP3 from the power supply assembly. 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:

4 Description of modules 91xx pH/Electrolyte AnalyzersDescription of modules
Valve drivers The solenoids are activated by transistors Q9 - Q13. To open the solenoid, a 0.5-second 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.
Pump motor driver/cover sensor 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/Dconverter
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 (9180/9181only)
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.

Service manual · Version 2.0 A-35
91xx pH/Electrolyte Analyzers 4 Description of modulesDescription 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 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.

TEST ELECTRODES
This mode allows for the measurement and display of electrode voltages.
Standard A, Standard B or an external sample can be measured to determine electrode performance and provide measurement data useful in locating electrode calibration faults. Each electrode parameter will be displayed and the electrode voltage associated with the sample type selected can be observed.
Example displays
TEST SAMPLE SENSOR
In this mode, the sample sensor output is displayed which is useful for electrical adjustment or for troubleshooting sample sensor faults. A dry sample sensor should display a value of 100 with a range of 80 to 120. After verifying a dry sensor, aspiration of a clear fluid (i.e., water) should increase the displayed value by at least 40 units.
Example displays
TEST SnapPak SENSOR (9180 and 9181 only)
In this test, the SnapPak Sensor detects whether the ISE SnapPak™ is in place. "I" indicates that the ISE SnapPak™ is in place, "O" indicates that it is either not present or not completely seated.
Example display
TEST LANGUAGE SWITCH (9180 and 9181 only)
This mode displays the language selected for display and printout. To change the selection, set the language switch (located behind printer) to the desired language. The display will indicate the language choice according to the switch setting. To activate a new language, turn the analyzer off and back on with the switch set to the desired language.

TEST PINCH VALVES
This test turns on/off each solenoid valve as indicated and is useful to verify both electronic control and mechanical operation of each solenoid valve.
Example displays
TEST INTERFACE
The Interface Test can be used to verify correct operation of the RS232C serial port. To operate this test, jumper pin 2 and pin 3 of the rear interface connector prior to invoking the test. During the interface test, the analyzer sends out a test string and checks if it is received within a set period of time. If correct operation is observed after completion of the test, [INTERFACE OK] will be displayed.
TEST AMPLIFIER
The Amplifier Test displays ground, reference and output voltage of each input amplifier. The values displayed for each electrode channel will be dependent on the electrode inputs and may vary. Display of the ground should read between -10 mV and +10 mV with the reference voltage reading between -2490 mV and -2510 mV. With all inputs open, the display should read +/- 4095 for each channel. On the 9140/9180/9181, an additional display indicating the temperature voltage and temperature in degrees C is available to verify the temperature adjustment. On the 9110, the temperature reading should be between 36.8 and 37.2°C.

Service Codes are available and allow additional programming features. Following is a listing of the available Service Codes and functions:
Set Reset Service code description
ALL LLA This service code will enable the Ca2+ value during auto-(9181 only)
matic serum/blood measurement. Special precautions are necessary
to obtain the correct Ca2+ value due to sample exposure to room air.
CDC – Clears all Service Codes.
9110: Except SLC.
DEC CED Provides one additional digit of resolution for each measured
parameter for blood and serum samples. QC and Standard samples
are always displayed with high resolution. Urine samples are always
displayed in low resolution.
ECO OCE Allows the operator to run the instrument in the economy mode. The
instrument will enter the STANDBY MODE. This occurs at the time
of the next 2-point calibration when no samples have been analyzed
since the last 2-point calibration.
FIF IFI Allows printing of electrode voltages during printout of
measurements and calibrations. (not available for 9140)
LEM MEL 9180/9181 only!
This service code will print the last 20 error messages.
MGL LGM This service code is available only in the model 9140/9180/9181
analyzer and enables Ca2+ values to be displayed in mg/dL. The
normal mode displays values in mmol/L. QC and Standard results are
always displayed in mmol/L.
NOB BON 9180/9181 only!
This service code disables the beep.
QCC CCQ When this code is enabled, QC values will be reported in direct ISE
measurement instead of flame-equivalent values. In this mode,
correlation factors are NOT applied to the measured values.
SFC – 9180/9181 only!
This code allows the input of a percentage for the ISE SnapPakTM
counter.
SLC CLS 9110/9180/9181 only!
When this code is set, the current setting of the leasing counter, which
cannot be reset by the operator, is printed on the calibration report.

When this code is set, the [CHANGE PATIENT TEMPERATURE?]
menu will appear in the sampling process. The analyzer will perform
a temperature correction calculation to convert the measured results
for the desired patient temperature. The temperature will be reset
after each sample to 37°C unless NTD is entered. Temperature
corrections can only be performed in the range of 15 - 45°C.

The temperature adjustment is active only for models 9110/9140/9180/9181 and requires the temperature adjustment test plug for correct calibration of the temperature circuit.
Sample contacts adjustment (9110 only)
In preparation for correct electronic adjustment, several steps must be performed.
a To adjust the sample contacts
1 Slide the electrode holder forward and remove the electrode from the analyzer.
2 Disconnect the intake tube from the preheater.
3 Remove the trim panel (located below the needle mechanism) and disconnect the plug for sample contact 1.
4 Select [TEST SAMPLE CONTACTS] in the [SERVICE FUNCTIONS] menu and adjust R10 (Display Board) for a reading of 140.
5 Reconnect sample contact 1 plug, intake tubing and electrode.
6 Check to ensure the value (140) remains the same.
e For details, see Error messages and troubleshooting on page D-5.

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

13 Troubleshooting 91xx pH/Electrolyte AnalyzersError 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.

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.
