Important information
Important information
This Service Manual contains vital warning and safety information.
This instruments are intended to be used only for the specialized purpose described
in the instructions. The most important prerequisites for use, operation, and safety
are explained to ensure smooth operation. No warranty or liability claims will be
covered if the instrument is used in ways other than those described or if the
necessary prerequisites and safety measures are not observed.
The instrument may be operated only by persons whose qualifications enable them to
comply with the safety measures that are necessary during operation of the
instrument.
Suitable protective equipment, like laboratory clothing, protective gloves, protective
goggles and if necessary mouth protectors, must be worn to prevent direct contact
with biological working materials. In addition, a face mask is required if there is a
risk.
Adjustments and maintenance performed with removed covers and connected power
may be attempted only by a qualified technician who is aware of the associated
dangers.
Instrument repairs are to be performed only by the manufacturer or qualified service
personnel.
Only accessories and supplies either delivered by or approved by Roche are to be used
with the instrument. These items are manufactured especially for use with this
instrument and meet the highest quality requirements.
Operation of the instrument with solutions whose composition is not consistent with
that of the original solutions can negatively affect, above all, the long term
measurement accuracy. Deviations in the composition of the solutions can also
decrease the service life of the electrodes.
The quality control requirements must be completed at least once daily for safety
reasons. Because accurate measurement results depend not only on the proper
functioning of the instrument, but also on a number of other factors (such as
preanalytics), the results produced by the instrument should be examined by a
trained expert before subsequent decisions are reached that are based on the
measurement values.

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.

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.

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.
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.
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.

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

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.
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.

is still available and has to be used for 9180 Electrolyte Analyzers SN < 11999.
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.
Note
Due to the update of the 9180 Electrolyte Analyzer according to IVDD compliance the printouts,
display messages and data links sequences of the 9180 Electrolyte Analyzers serial number > 12001
will show "Roche" instead of "AVL". This also applies to 9180 Electrolyte Analyzers serial number
< 11999 in case of replacing the main board "MAINBOARD 9180 >SN 12001" or the program set
"PROGRAM SET 9180".

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.

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.

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.

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.

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

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.

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.
Note
If the value drops after reconnecting each of the three sample contacts, follow the troubleshooting
guidelines for fault isolation.
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.

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.
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.

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.

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.
