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.

ESD protection measures

ESD protection measures

ESD = Electrostatic Sensitive Device

Explanation of the phenomenon

The most frequent cause of electrostatic discharge is friction of various materials such
as plastic, synthetic fiber, hard rubber or paper.

It can also be caused by bending or applying pressure to a material.

Discharges that are dangerous to components occur when "charged" bodies or
components do not have a discharge connection (ground) to discharge the
electrostatic charge.

The discharges normally do not have a high capacity, but there are often voltage
differences in the range of several thousand volts. The discharges are perceived as
small shocks or visible sparks.

Examples: o Shoes with rubber soles:

Friction is caused by walking. A person develops an electrical charge different
from the ground. A discharge occurs when an object (e.g. door handle) is
contacted.

o Synthetic fiber clothing:

Discharge is audible and is visible in darkness.

The dryer the air the greater the risk of electrical discharge caused by friction.

Eectrostatic charges are less likely to build up in humid air, particularly when saturated with water
vapor.

The probability of ESD phenomena is therefore particularly great in a northern hemisphere winter
in centrally heated rooms where the humidity is low.

Influence of electrostatic charges on components

If a person with an electrostatic charge touches a component, a discharge over a
connection of an IC or semiconductor element may occur. The resulting voltages may
damage the component.

Critical situations can occur while repairing or testing components if they are lying
on a more or less conductive surface (e.g. table top) and a person with an electrostatic
charge touches them. A discharge through a critical component connection can also
occur in this case.

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.

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.

Software

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)

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.

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.

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 (→).

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.

Needle unit assembly

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.

the electrode module until detected by Sample Contact 3 (bridge between sample
preheater tube and reference electrode). Then, the pump stops.

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 SnapPak

TM

, 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.

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 SnapPak

TM

.

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

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:

Valve d r iv e rs 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

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 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.

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.

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 -V

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.
