1 Safety information 91xx pH/Electrolyte AnalyzersESD protection measures

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.



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

Interface specifications

Interface information

The 9110, 9120, 9130, 9140, 9180 and 9181 analyzers are equipped with a standard serial interface output. This interface output is intended to be used with standard commercially available computer systems.

The data transmitted through the serial interface port employs the ASCII code.

The serial interface is terminated on the rear cover with a 9-pin male DB-9 connector.

The signal levels are as follows:

o Binary 1 = -12 V to -3 V

o Binary 0 = +3 V to +12 V

Two stop bits follow the eight data bits to complete the 10 bit word.

The baud rate is set at 9600 Baud fixed.

The maximal recommended cable length is 40 feet.

The pin assignment is as follows:

o pin 1...sample ground...GND

o pin 2...receive data....RxD

o pin 3...send data.......TxD

o pin 4...NC

o pin 5...signal ground...GND

o pin 6...NC

o pin 7...RTS (not used)

o pin 8...CTS(not used)

o pin 9...NC

(NC=Not Connected)

Software

The patient sample data is sent at the end of each measurement, the calibration report is sent at the end of each calibration.

The interface is always on, independent of the printer settings; the data is always sent.

Higher discharge current

A higher discharge current can be expected when using the serial interface. This must be checked by

suitably qualified personnel, depending on the local regulations.

Note

The arrow up (e.g. out of normal range) is sent as HEX 18 (↑), the arrow down as HEX19 (↓) and

the ° (degree) is sent as HEX1A (→).

Data Link Information (9180/9181 only)

The data link with the COMPACT 2/3 blood gas analyzer allows to combine ISE results with pH/blood gas results on one printout. If Ca2+ is activated on the 9180/9181, a pH-corrected Ca2+ value will be calculated and printed on the combined sample report.

For connection of the 9180/9181 analyzer to the COMPACT 2/3 analyzer, the optional Interface Kit is required. To install the kit, first turn both instruments off. Connect the interface filter provided in the kit to the RS232 port on the 9180/9181. Then connect one end of the cable to the interface filter, the other end to the COM 2 port on the COMPACT 2/3. On the COMPACT 2/3, select 9180 under the COM 2 interface options.

Mechanical assemblies

Front door assembly

For the 9110, 20, 30, 40 and 80 analyzers, the front door can be removed by moving the analyzer to the edge of a work surface so the analyzer door, when opened, will extend past the edge of the work surface. With one hand, hold the analyzer door near the right side hinge pin and, with the other hand, gently apply pressure to the middle rear area of the door. This will allow the right hinge pin to clear the retaining hole in the main chassis. The door can then be removed from the analyzer.

The 9181 front panel can be removed by tilting it slightly away from the analyzer and lifting it straight up. The plastic window can also be replaced in the field by gently pressing from the rear of the window and snapping the plastic window out toward the front of the analyzer door. The door magnets cannot be replaced in the field as they are glued in place with conductive adhesive.

e See the 91xx Spare Parts List for a detailed reference of the parts of this assembly.

Needle unit assembly

To remove the 9110 fill port for replacement or cleaning, grasp the white tab on the fill port and rotate the bayonet-style connector counter-clockwise. Gently pull the fill port forward to remove. Replacement can be accomplished in the reverse order. During removal, be careful not to bend the needle.

The 9110 fill port assembly is desinged for easy removal without the use of tools, for cleaning, changing tubing or replacement. First, disconnect the sample intake tube on the left side of the fill port assembly from the sample preheater. Grasp the fill port assembly and pull it forward carefully. Disconnect the wire from the needle arm. To reassemble, reconnect the wire, press the fill port assembly into place and reconnect the tubing.

The 9110 wash port located on the underside of the flap can be removed by appying pressure to one side to overcome the snap fit. To reinsert, align wash port and apply pressure to snap into place.

The 9120, 30, 40, 80 and 81 sample needle and fill port are both designed for easy replacement by the user. To remove the fill port assembly for replacement, pull the fill

After changing any part of the analyzer always perform a calibration of the analyzer as well as a full

QC measurement. QC measurements must be performed in their entirety (i.e., all three QC levels

must be measured). Omitting QC measurements or ignoring QC measurement results may lead to

incorrect patient measurements, which may result in incorrect clinical decisions, possibly

endangering the patient's health.

Due to the update of the 9180 Electrolyte Analyzer according to IVDD compliance a new shielded

front door "FRONT DOOR 9180" is available and compatible with any 9180 Electrolyte Analyzer

(old type SN < 11999 and new type SN > 12001) and with 9120, 30, 40 Electrolyte Analyzers.

Further information: see the 91xx Spare Parts List.

port holder towards the front for easy access. Then, press the two plastic tabs on the fill port to allow removal of the fill port from the fill port holder. The sample needle can also be removed and is supplied as a one-piece assembly including the intake tubing.

To remove the 9120, 30, 40, 80 and 81 sample needle, grasp the needle near the white holder block and pull up to unsnap the sample needle from its position. To replace the assembly, align a replacement sample needle and press the replacement assembly into place.

Two (9110) or three screws (9120, 30, 40, 80, 81) located on the left side of the assembly hold the needle unit assembly in place. To access the two rear screws, turn power off and remove the rear panel. The rear panel can be moved away from the unit for easier access by unplugging the wire harness from the power supply. The SBC board can now be removed by removing the screws which secure the SBC board and disconnecting the cables on the SBC board.

Disconnect the connector to the lamp board which supplies the Door Open signal. The two rear screws which secure the needle unit can now be removed using a Philips screwdriver (9110) or an Allen wrench (9120, 30, 40, 80, 81). Then, remove the front securing screw (n./a. on the 9110), the sample intake tubing and the reagent supply tubing (red tag) from the fill port. The needle unit can now be removed from the front of the analyzer for replacement.

e See the 91xx Spare Parts List for a detailed reference of the parts of the needle unit.

Electrode holder assembly

To remove the electrode holder assembly from the analyzer, first unplug the sample intake tubing on the right side of the module, then the preheater cable (9110 only) or the sample sensor cable (9120, 30, 40, 80 and 81), then remove the reference solution tubing connector and last, take out the waste tube (green tag) at the left side of the electrode holder. The electrode holder can now be removed by pressing the two plastic tabs (right and left side of the module) and sliding the module forward. Press the plastic tabs again to release the second detent and completely remove the module from the analyzer. The sample preheater or the sample sensor and/or the left side electrode holder can be removed and replaced by removing the screws on the under side of this module.

e See the 91xx Spare Parts List for a detailed reference of the parts of this assembly.

Peristaltic pump assembly

Replacement of the roller assembly of the peristaltic pump can be accomplished by removing the pump tubing and firmly pulling the roller assembly toward the front. To replace the roller assembly, align the roller and the flat on the motor shaft and press the replacement roller into position.

To remove the motor, first remove the rear panel assembly and SBC Board.

e For details, see Rear panel assembly on page A-25, SBC board on page A-26.

Now, the electrical connector on the lamp board can be accessed to unplug the motor connector. The motor can now be removed by removing four screws located on the front of the housing near the peristaltic pump.




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.


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. The power supply module located on the rear panel assembly can now be removed by removing the three screws securing the circuit board and by disconnecting the wiring

Note

The 9110 R-solenoid incorporates two heat sinks and is not interchangeable with the other

solenoids.

Note

Never attempt to dislodge paper from the printer with a paper clip or similar object to avoid

damage to the print head or printer platen.

Due to the update of the 9180 Electrolyte Analyzer according to IVDD compliance a new printer

assembly "PRINTER MODULE, ISE" is available and compatible with 9110 pH Analyzers and

with any 9120, 30, 40, 80 and 81 Electrolyte Analyzer.

interconnections. The main power receptacle can also be replaced by removing the two screws holding this assembly.

SBC board

After the rear panel has been removed, the SBC Board is accessible for removal. This circuit board can be removed by removing the seven screws securing the board to the housing and by disconnecting electrical connectors from the power supply module, display board and lamp board.

e For details, see Rear panel assembly on page A-25.

The electrode push pins can now be replaced by simply pulling the connecting pin from its socket. When installing the board, make sure to place the plastic washers under the screw heads.

Due to the update of the 9180 Electrolyte Analyzer according to IVDD compliance a new power

supply module "POWER SUPPLY 9180 >SN 12001" is available and compatible with 9180

Electrolyte Analyzers serial number > 12001 only.

The former power supply "MODULE POWER SUPPLY, ISE" is still available and has to be used

for 9180 Electrolyte Analyzers SN < 11999, for 9110 pH Analyzers and for 9120, 30, 40 and 81

Electrolyte Analyzers.

e Further information: see the 91xx Spare Parts List.

After changing the main board or the power supply always perform a measurement of protective

ground resistance to ensure a safe connection of the system ground. Always measure with the power

cord attached to the analyzer. The resistance measurement has to be done between the ground pin

of the power plug and several ground connectors placed on each of the analyzer's electronic

components such as power supply or main board and shielding. The total resistance should not

exceed 0.5 ohms. Be sure to consider the resistance of the ohmmeter's connecting cables.

Due to the update of the 9180 Electrolyte Analyzer according to IVDD compliance a new SBC

board "MAINBOARD 9180 >SN 12001" is available and compatible with 9180 Electrolyte

< 11999 in case of replacing the main board "MAINBOARD 9180 >SN 12001" or the program set

"PROGRAM SET 9180".




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.


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) 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.




Sample Contacts (9110 only)

The 9110 fluid detection is based on the principle of measuring the impedance in a sample contact path. There are three sample contacts in the 9110 pH Analyzer. Sample Contact 1 senses standard solution draws.

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:

Table A-6 Voltage test points




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.




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.

91xx pH/Electrolyte Analyzers 10 Service functionsService functions

Service functions

The Service Functions mode provides a menu of service test functions to assist in failure diagnosis and identification. A logic flow chart is provided for reference of the sequences included in the Service Functions mode.

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.

Example display

TEST SAMPLE DOOR (except 9181)

This test verifies the operation of the sample door light gate and its associated circuitry. The display indicates an “O” or “C” depending on the position of the door.

Example display

TEST PROBE (9181 only)

This test verifies the operation of the sample probe motor, position sensor and associated circuitry. The "U" represents the output of the upper position sensor, the "L" represents the output of the lower position sensor.

Example display

TEST AUTOSAMPLER (9181 only)

This test verifies the operation of the Autosampler turntable assembly. The display indicates the output of both the position and home sensors.

Example display

TEST PUMP

This test turns on the peristaltic pump at each of the four pump speeds. The display indicates for two seconds each pump speed while each pump speed is being tested. Observe that the peristaltic pump changes speed as is indicated on the display.

Example displays

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.

ENTER SERVICE CODE

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.

SSC CSS 9181 only!

This code toggles needle height to accommodate smaller (9181 only)

sample cups. In the default setting, the analyzer works with 2.0 mL

cups. To select 0.25 mL sample cups, SSC has to be activated. To

return to the default setting, CSS has to be activated.

CHP PHC This code allows for the display and printout of pH results in

concentration of H+ ions. The cH+ will be shown in addition to the

pH value. cH+ is not shown on QC values and statistics reports.

Table B-1 Service code descriptions




EXW WXE 9110 only!

This code extends the wash cycle following a serum or blood

measurement. Normally 10 Standard A segments are used for the

wash cycle; with EXW set, 20 Standard A segments will be used.

NTD DTN 9110 only!

When the code TMP is set, NTD prevents the temperature from

91xx pH/Electrolyte Analyzers 11 AdjustmentsAdjustments

Adjustments

The 9110, 20, 30, 40, 80 and 81 Analyzers have been designed to require minimal electronic adjustment. The sample contact circuit may require adjustment following a change of the sample contact components or during a routine troubleshooting (9110 only) or the sample sensor circuit may require adjustment following a change of the sample sensor or during routine troubleshooting. 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.

Sample sensor adjustment (9120/9130/9140/9180/9181 only)

a To adjust the sample sensor

1 Select [TEST SAMPLE SENSOR] in the [SERVICE FUNCTIONS] menu which will display the current sample sensor setting.

2 Adjust R93 Sample Sensor Adjust located at the top of the ISE SBC card to a value of 100.

3 Press YES to turn on peristaltic pump and ensure displayed value remains constant.

Raise sample door and aspirate clear fluid (e.g. water). Displayed reading should now be 150 or greater.

a To adjust the temperature amplifier

1 Select [AMPLIFIER TEST] in the [SERVICE FUNCTIONS] menu which will display the current amplifier voltages.

2 Press NO twice to display the temperature voltage and actual temperature display.

3 Unplug the preheater (9110 only) or the sample sensor and fit the Temperature Adjustment Test Plug in place of the preheater or sample sensor plug.

4 Adjust R54 located on the SBC Board for a display of 3000 mV.

5 Unplug the Temperature Adjustment Test Plug and fit the preheater or the sample sensor connector to display the actual temperature.

9110 Wait 5 minutes for the preheater to stabilize. The display should now read 37.0±0.2°C. Adjust R20 on the display board (clockwise to increase) for 37.0±0.1°C.

9140/9180/9181 Due to the elevated temperature inside the analyzer, it is normal for the displayed temperature to be several degrees C higher than the actual room temperature.

If no Temperature Adjustment Test Plug is available, place a quality thermometer (preferably mercury) next to the right side electrode holder. With the front door open, wait approx. 10 min. Then adjust the displayed temperature to match the reading on the thermometer.

Error messages and troubleshooting

Status-LEDs

The 5 status LEDs at the bottom of the chassis back panel are lit simultaneously during normal operation. See below if any LED is blank.

Possible causes and remedies

o One ore more supply voltages are out of range or missing. Check the voltage test points.

e For details, see Power circuits on page A-33.

o If the voltages are correct:

O Check subsequent cicuits and cabling for obvious damage and replace, if necessary.

O Check and replace the corresponding fuse.

o Replace the SBC board.

o Replace the power supply.

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

Figure D-1 Status LEDs (back panel, bottom)



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.


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 Check for correct drying of measuring chamber during the wash cycle.

o Replace peristaltic pump tube set.

9110 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.

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.


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)
