1.3 PRECAUTIONARY MEASURES
1.3.1 CHEMICAL RISKS
The individual operator is responsible for assuring that all possible precautionary measures are
taken against eventual risks associated with the use of the “Ellipse” instrument in clinical laboratory
settings. The manufacturer will provide the reagents kit and specific written information on the use
of each of the reagents.
It is important that the samples be well coagulated and then carefully centrifuged.
Samples which contain fibrinogen clots can obstruct the probe and lead to inexact sampling.
If blood samples containing gel are used, it is suggested that the manufacturer’s recommendations
be followed.
Immediately clean and remove any accidental leakage of reagent or other liquid.
1.3.2 ELECTRICAL RISKS
As with any electrical device, the risk of electric shock exists.
Is therefore necessary to take every precautionary measure possible when working with this, or any
other, electrical instrument to avoid contact with power supply wires, electrical components or
electronic boards.
1.3.3 MECHANICAL RISKS
Several precautionary measures should be taken when operating the analyzer:
avoid wearing very loose clothing or jewelry that could become tangled in the instrument’s moving
parts (e.g. the sample probe); whenever possible, operate the instrument with the main cover panel
lowered.
WARNING: Never attempt to service or substitute any part(s) of the analyzer when the
instrument is turned on.
Any and all technical repairs or servicing must be performed by specialized personnel only.

2 DESCRIPTION OF THE SYSTEM
"Ellipse" is a random access, computer controlled, counter-top, clinical analysis instrument. The
system can perform 138 tests per hour and has a machine cycle of 26 seconds. Its execution time
ranges from a minimum of 18 seconds to a maximum of 1032, depending on the analysis method
chosen.
The first time the system is used for laboratory analyses, the operator must configure the system
based on the specific needs of that laboratory; i.e.: the chemistry parameters and the reagents racks,
along with the normal ranges, calibrated and control values, must all be defined.
The daily routine analyses will be carried out according to patient sample arrival in a sequential and
continuous, non-stop manner.
The work list is organized using a loading rack holding up to 8 patient samples. Rack loading is
non-stop.
The racks can accommodate both test tubes and micro cups. The bar code for primary tubes and
reagent containers is an optional feature.
When the system, the analytical unit and the computer, is turned on the color-meter lamp is supplied
with low voltage power (1.2 volts), the sampling arm pre-heater remains turned off, while instead
the reaction plate heater, the reagents refrigerating unit (optional module) and the electronic
components are turned on.
In this phase, the "Stand-by" light, placed on the front panel, will flash until the reaction plate
reaches a temperature of 36° C. When this temperature is reached, the "Stand-by" light will stop
flashing and will remain constantly lit.
In the case of system failure or malfunction, the "Ready" light, situated on the front panel of the
instrument, will light up red.
In order to access the main program, double click on the "Ellipse" icon on the computer desktop.
The main menu - "System Monitor" - will appear.
Whenever any system function is launched, the color-meter lamp and the sampling arm pre-heater
will receive regular power.
Chapter 02 – SYSTEM DESCRIPTION
Ellipse Service Manual Rev. 03 01 June 2009 Page 3
2.1 ANALYSES CYCLE
2.1.1 REACTION PLATE
The reaction plate of the "Ellipse" system contains 6 disposable racks with 20 reaction cuvettes
each.
The racks can be removed individually.
The basic operating cycle of the reaction plate takes 26 seconds. This cycle includes: optic reading
of the cuvettes in incubation, aspiration and dispensing of the reagents and the samples by the arm,
along with the relative positioning of the plate .
The reactions take place at 37° C. This temperature is maintained constant by a controlled heating
unit placed under the reaction plate .
2.1.2 REACTION PLATE CYCLE
After reagents and samples have been placed in cuvette #1, the reaction plate will rotate 40
positions counter-clockwise, so as to bring the first cuvette to be analyzed in front of the color-
meter for reading with either one or two wavelengths, as required.
The plate will then, moving counter-clockwise, carry out all the readings of any other prepared
cuvettes. After having effectuated all the readings, the plate will move counter-clockwise to its
initial position minus one cuvette, ready for a new dispensing.
In this manner, the reaction cuvettes move clockwise 1 - 2 - 3 – 4 for dispensing, washing and for
their relative readings.
2.2 SAMPLING ARM - OPERATIONAL SEQUENCE
1. The sampling arm lifts up from the wash well and carries out a wash cycle;
2. The arm moves toward the specific reagent container, while the diluter aspirates an air
bubble to separate the rinse column from the reagent;
3. The arm lowers itself into the reagent, below the level indicated by the sensor, and aspirates
the required quantity of reagent. If the method requires a Rinse (used in order to reduce the
possibility of negative contamination between the water column and the reagent) an extra
amount of reagent (not used in the analysis) will be aspirated before the quantity of reagent
necessary for the analysis, along with another air bubble for their separation;
Chapter 02 – SYSTEM DESCRIPTION
Ellipse Service Manual Rev. 03 01 June 2009 Page 4
4. While the diluter aspirates a second air bubble, the arm rises and then lowers into the wash
well so that it can be washed externally, to minimize cross contamination;
5. The arm moves to the specified sample and aspirates a third air bubble;
6. Once the level sensor has indicated the presence of the liquid, the arm stops and aspirates
the sample;
7. The arm once again is raised, while the diluter aspirates a fourth air bubble to prevent
sample loss;
8. At this point, the arm returns to the wash well in order to clean the outside of the probe and
aspirates a fifth air bubble;
9. The arm moves to the reaction PLATE , dispenses, and mixes the reagent and sample in the
reaction cuvette for incubation and reading;
10. The arm returns to the wash well and carries out a probe wash cycle.

2.3 WASH STATION
The reaction plate wash station is made up of a series of five small needles situated on one side of
the reaction PLATE . Said needles are opportunely connected to the valve and pump system for
emptying, washing and drying operations (please see the hydraulic diagram).
2.3.1 WASH STATION CYCLE
The wash station carries out its operations alternating upward and downward movement. In its
downward movement phase the needles are guided in such a manner as to carry out the following
operations:
• The first needle, using the central cannula, removes the reaction mix while the external
cannula dispenses, shower-like fashion, the wash solution; after that the external
cannula dispenses wash solution and then the liquid is aspirated from the central
cannula;
• The second needle operates exactly like the first but uses distilled water instead;
• The third needle operates exactly like the first but dispenses rinse solution into the
cuvette so that an optics check can be performed (if the results are negative, the cuvette
is discarded);
• The fourth needle aspirates the control water;
• The fifth needles dries the sides.
All these operations are part of the routine operation of the instrument. Every reaction cuvette is
washed at the end of each round of analysis.
The reusability (optical integrity) of each reaction cuvette is always tested before the next round of
analysis.

signals for managing the relevant devices (the vertical sampling arm home sensor, the
horizontal sampling arm home sensor, the diluter home sensor, the diluter electrovalve
and pump, the preheater, the level sensor assembly, the temperature service probe, the
main alarmed fan, the three buttons – indicators of the Control Panel);
the Stepper Motors Driver Board from which the Arm Interface Board receives the
command signals for the stepper motors of the following relevant devices: vertical and
horizontal sampling arm, Diluter, peristaltic pump;
the Control Panel Board for the three buttons-indicators checking.
Chapter 02 – SYSTEM DESCRIPTION
Ellipse Service Manual Rev. 03 01 June 2009 Page 10
There are also the following three led:
o the yellow led (LD1), active when the preheater is powered;
o the red led (LD2), active when there is a signal from the sampling arm leaking sensor;
o the yellow led (LD3), light on when the level sensor is activated.
The power supply, by a specific power line cable, supplies +24 VDC and +12 VDC to the board. +5
VDC needed to the Arm Interface Board is generated on the same board by a voltage regulator. All
the components managing respective devices are mounted on this board.
2.4.6 ELECTROVALVES CONTROL BOARD [P/N: 30-01626-00]
This board communicates with the Analytical Control Board all the I/O signals for managing all the
relevant devices (electrovalves and micropumps related to the washing station, the washing well
and the peristaltic pump; the bottles liquid sensors; the waste sensors; the main cover switch).
The red led (LD1) is active when there is a signal from the washing station leaking sensor;
From the Analytical Control Board the Electrovalves control board receives the +24 VDC . +5
VDC is generated from + 24VDC by a voltage regulator. All the components managing respective
devices are mounted on this board.
2.4.7 PRE-AMPL/ADC [P/N: 30-00107-00; P/N: 30-00107-03]
The Pre-Ampl/ADC board P/N: 30-00107-00 is used for reading the signals from the photometer
main channel, while the Pre-Ampl/ADC P/N: 30-00107-03 has the same function for the
photometer reference channel. They are mounted on the photometer assembly and directly linked to
the Analytical Control Board, by two distinct flat cables, for transmitting all the I/O signals. The
only difference between them is the R1 resistor value. On the boards, the (FD1) photodiode reveals
the signal arriving from the relevant reading channel; the Amplifier (U2) amplifies the signal, which
is then inputted in the serial converter ADS 1250 (U3) for its conversion A/D.
From the Analytical Control Board they receive also two continuous voltages (+VB and –VB).
All the components dedicated to the signal amplification or digital conversion are mounted on the
same boards.

2.4.8 PHOTOMETER LAMP BOARD [P/N: 30-01576-00]
This board is linked to the Plate Interface Board (Sx) from which receives the check signal (coming
from the Analytical Control Board) to regulate the light intensity of the photometer halogen lamp
(+6V, 10W). From the interface board receives the continuous voltage (VL) which is then converted
to +6 VDC on the same board, by a voltage regulator, for powering the lamp.
2.4.9 CONTROL PANEL BOARD [P/N: 30-01850-00]
This board is linked to the Arm Interface Board (Sx) to which transmits the I/O signals from the 3
lighting buttons of the Control Panel.
From the interface board receives also the continuous voltage (VB) for the three buttons – indicators
functionality.
2.4.10 LEVEL SENSOR ASSY [P/N: 10-01478-00]
The level sensor assembly is composed by the level sensor board “A” (P/N:30-01392-00) and the
level sensor board “B” (P/N:30-01392-01).
The level sensor assembly, installed on the sampling probe head, is linked to the Arm interface
board. By a specific cable it transmits the relevant signal (the capacity variation produced by the
contact between the sampling probe and the liquid) to the Analytical Control Board.
Level sensor components and integrated circuits are mounted on the level sensor assembly.

3.1 UNPACKING
The ELLIPSE is packed and delivered in two separate wooden crates: one contains the
analyzer itself and the other the computer, along with its accessories. In the event that the order
not include the PC component, packing and delivery will involve one wooden crate plus a
corrugated cardboard box. The packing has been expressly studied and designed to insure
maximum protection of the contents during shipping and handling. It is therefore extremely
important that the crate(s)/box be carefully examined upon delivery in order to ascertain their
integrity. Special attention should be dedicated to examining the color of the “Shock Watch”
glued to the crates, which must show the color ‘white’. A ‘red’ “Shock Watch” indicates that
the crate(s) have experienced some sort of ‘shock’ during handling, transport and/or delivery.
This fact must be noted by the courier on the delivery note, as must any and all visible external
damage (for example: holes, dents, rips or tears, water marks, etc.) evident at the moment of
delivery. This will simplify matters in the event of any future claims for damages.
MAKE SURE THAT THE UNPACKING IS CARRIED OUT BY TWO PEOPLE.

Upon arrival of the crate(s)/box, take out the
delivery note and make sure that all the items
on the packing list are included in the crates
and are undamaged. Make sure the series
number on the delivery note/packing list
corresponds to that impressed on the plate on
the right side of the instrument.
Open the crate(s)/box from the top and very
carefully take out:
- the instrument;
- the computer and accessories.
Chapter 03 - INSTALLATION
Ellipse Service Manual Rev. 03 01 June 2009 Page 3
Do not discard the delivery crate(s)/box or the packing material until the correct functioning of
the instrument has been ascertained.
Remove all the items from the crate(s)/box very carefully.
Remove the adhesive tape from the cover of the samples and reagents housing, from the front
panels and from the samples and reagents racks.
Before connecting the "Ellipse", remove the protective packing material placed under the
sampling arm and under the wash station group.
Warning: in the event that it is necessary to repack any or all of the delivered item(s), the
following procedures must be carefully followed:
¾ Reposition the protective packing material under the sampling arm and under the wash
station group.
¾ Tape down (using masking tape if possible) the cover of the samples and reagents housing,
the front panels, and the samples and reagents racks.
¾ Remove the probe from the sampling arm and place it inside a cuvette. Then cap the
cuvette and tape the cap down.
¾ Be very careful to not bend the wash station cannulas when repositioning the protective
packing material.
¾ Fill the empty spaces around the accessories packed in the crate using “pluriballs” or other
suitable packing material.

5 DIAGNOSTIC PROGRAM
The diagnostic program enables the operator to perform a complete check of each of the Ellipse’
module functions.
This program has a folder structure, with each folder containing functions pertaining to the specific
module. To launch the program the operator has to click with the left side of the mouse, on the
Diagnostic area located on the lower right side of the screen of the System Monitor (Fig.1).
The Ellipse must be in the stand-by state to access this area.

Gap: defines the volume, in µL, of the air bubble that separates the Rinse (the liquid column into the
sampling arm tube) from the sampled reagent; this volume must be set in the range from 10 to 24
(Standard value 16).
For the correct setting of the gap volume it is necessary to apply the procedure of BIB (Precision
check of the Analytical plate) and BIC (Volume precision check of the Sampling line).
If BIC’s CV values should exceed the limit specified below, the GAP has to be increased by
steps of 2 µL (starting from 10 µL) until obtaining the expected BIC’s CV value
Precision check of the Analytical plate BIB
Prepare two series of 32 samples each by using a diluted solution of K2Cr2O7 (obtained from 4
gr/l concentrated solution diluted 1:100 with Rinse solution (distilled water + 1000 µL/litre of Brij))
Use the same solution as samples and reagent
Program a new method with the following parameters:
Method name: BIB

7.3 SAMPLING PROBE – CLEANING PROCEDURE
1) Turn off the Analyzer
2) Use only lint-free paper towelling or gauze
3) Dampen the gauze or paper towelling with distilled water and clean the outside of the
sampling probe. Wipe the probe from the top downwards only! This is to avoid that
any bits of cloth, paper or lint fibres accidentally enter the probe itself.
4) The manufacturer suggests that once weekly the above-described cleaning procedure
be performed using, instead of only simple distilled water, a 5% sodium hypochlorite
solution to dampen the gauze and then be repeated using distilled water.
7.4 WASH STATION CANNULAS – CLEANING PROCEDURE
1) Turn off the Analyzer.
2) Place a sheet of paper under the wash station cannulas in order to keep any extraneous
material from accidentally falling into the cuvettes.
3) Use only lint-free paper towelling or gauze.
4) Dampen the gauze or paper towelling with distilled water and clean the outside of the
cannulas. Wipe the cannulas from the top downwards only! This is to avoid that any
bits of cloth, paper or lint fibres accidentally enter the cannulas themselves.
5) The manufacturer suggests that once weekly the above-described cleaning procedure
be performed using, instead of only simple distilled water, a 5% sodium hypochlorite
solution to dampen the gauze and then be repeated using distilled water.
7.5 WASH SOLUTION BOTTLES – CLEANING
During normal use and over time, mold and dust can build up inside the wash solution bottles.
For this reason, it is extremely important that they be periodically washed. Said cleaning must be
thorough and meticulous in order to insure that every trace of mold or residue be removed.
How often the bottles must be cleaned depends on their use and on the quality of the distilled water
used in that particular laboratory. However, the manufacturer recommends thorough washing at least
once every two weeks.
It is extremely important that the user not underestimate the risks associated with mold and dust
particles. They are to be regarded as a serious hazard as they can be the cause of instrument
malfunction.
The wash solution bottles are located on the right side of the analyzer.
Chapter 07 - MAINTENANCE
Ellipse Service Manual Rev. 03 01 June 2009 Page 6
7.5.1 WASH SOLUTION BOTTLES - CLEANING PROCEDURE
1) Turn off the Analyzer.
2) Pull the level sensor connectors out from the bottle caps.
3) Take the caps off the bottles and empty them.
4) Fill each bottle with a 5% sodium hypochlorite solution.
5) Clean the inside of each bottle using a bottlebrush in order to remove all traces of mold
and/or residue.
6) Leave the sodium hypochlorite solution stand in the bottles for at least ten minutes.
7) Empty the bottles, rinse them repeatedly and well with tap water, and then twice more
using distilled water.
8) Dry the bottles.
9) Fill the bottles with their proper solutions.
10) Replace the bottles in their respective housings.
11) Close the bottles and reconnect the level sensors.
12) Carry out two ‘Wash Cuvettes’ cycles and two ‘WBL’ cycles. Check system efficiency
by comparing the WBL values and the test results obtained against the laboratory’s
quality control values.
7.6 TIP WASHING
The Tip is used to dry the cuvettes after they have been washed. This drying process is carried out via
aspiration and therefore, over time, the Tip will necessarily absorb various contaminating particles.
The manufacturer suggests that the Tip be replaced every six months. Said frequency may vary
depending on the workload of the individual laboratory and the operating conditions/environment of
the single instrument.
The Tip must be washed regularly in order to guarantee proper functioning and must be replaced with
a new Tip as necessary.

7.7 HYDRAULIC CIRCUIT WASHING
During normal use and over time, mold and dust can build up inside the wash bottles and can have a
negative effect on the hydraulic circuit, compromising the correct functioning of the micro-pump and
valves. This, in turn, can lead to inefficiency in the sampling probe and cuvette washing system.
For this reason, it is extremely important that the hydraulic circuit be periodically washed. Said
cleaning must be thorough and meticulous in order to assure that every trace of mold or residue be
removed.
How often the hydraulic circuit must be washed depends on the operating conditions/environment of
the single instrument and the quality of the distilled water used in that particular laboratory. The
manufacturer recommends thorough washing at least once a month.
It is extremely important that the user not underestimate the risks associated with mold and dust
particles. They are to be regarded as a serious hazard as they can be the cause of instrument
malfunction.
The hydraulic circuit input cannulas are located inside the bottles on the left side of the Analyzer.
7.7.1 HYDRAULIC CIRCUIT - CLEANING PROCEDURE
1) Turn on the Analyzer.
2) Prepare a bottle containing 500 ml of a 5% sodium hypochlorite solution
3) Insert the four aspiration cannulas, located inside the liquids bottles, into the bottle containing
the sodium hypochlorite solution.
4) Have the instrument carry out a ‘WBL’ cycle and then a ‘Wash cuvettes’ cycle.
5) Wait for fifteen minutes. Clean and dry the three cannulas and then insert them into a bottle
containing distilled water.
6) Have the instrument carry out a ‘WBL’ cycle and then a ‘Wash cuvettes’ cycle.
7) Insert the four aspiration cannulas back into their respective bottles. Said bottles should have,
in the meantime, been cleaned and filled with a fresh supply of the required solution.
8) Have the instrument carry out a ‘WBL’ cycle and then a ‘Wash cuvettes’ cycle. Check system
efficiency by comparing the WBL values and the test results obtained against the laboratory’s
quality control values.

8.2 PROTOCOL SPECIFICATIONS
This part of Help (Protocol Specifications) contains information for the laboratory computer and
analyzer. This exchange of data follows specific ASTM protocols:
E 1381-95 Standard Specification for Low-Level Protocol to Transfer Messages
between Clinical Laboratory Instruments and Computer Systems;
E 1394-97 Standard Specification for Transferring Information between Clinical
Instruments and Computer Systems.
ASTM uses a number of different terms to indicate the way it groups data.
• Field: an individual piece of data often referred to as a data field or a data element.
• Record: a number of logically related data fields grouped together to form one part of a
complete message.
• Repeat field: a data field of the same type as the one immediately preceding it. A delimiter
separates one instance of a repeat field from the next.
• Component field: part of data field that might contain more than one piece of data.
The default communication configuration for the Analyzer is the following: "9600,N, 8,1".
ASTM uses record types that are common and familiar to all laboratory personnel. It uses the
following record types:
• Header Record (H): contains identifying information about the sending station,
conventions that the device uses for field recognition, and the date and time of send station
transmission.
Chapter 08 – Host Communication
Ellipse Service Manual Rev. 04 01 October 2009 Page 4
• Patient Record (P): contains patient information and identification number.
• Test Order Record (O): contains information about the assay or requests themselves and
includes other data.
• Result Record (R): contains information about the outcome of individual tests for an
individual patient and follows a sample program record. The results contain the actual
measurements derived from the test and a comparison of the individual result to certain
ranges specified as norms for the laboratory.
• Message Terminator Record (L): although the ASTM protocol supports three additional
record types - a Request for Information Record, a Scientific Record and a Manufacturer's
Information Record - the Analyzer is not implementing these in the first release and will
ignore them.
• Request Information Record (Q): is used by either clinical instruments or computer
systems for a remote request for information from its reciprocal system.
The instrument does not send or accept comment records.

Chapter 09 - ERROR SIGNALING AND TROUBLESHOOTING
Ellipse Service Manual Rev. 03 01 June 2009 Page 2
9.1 ERROR SIGNALING
This chapter is dedicated to a description of the error signalling which may occur during the
programming or carrying out of the various operations. Error signals can be divided into the
following two groups:
➢ System Errors
➢ Result Flags
9.1.1 SYSTEM ERRORS
Whenever a system error is detected, it is signalled via the activation of the below-listed
warning lights/buttons:
➢ Warning Light: a triangle-shape located in the upper, right-hand portion of the System
Monitor screen. It lights up yellow when activated.
If this yellow triangle does light up, the operator need simply click on it to access the relative
visual text warning message indicating the cause of the signalled anomaly (said window will
open in that area dedicated to viewing data).
Following is a list of possible visual text “Warning!” messages:
• Liquid Alarm I (Rinse Solution)
• Liquid Alarm II (Distilled Water)
• Liquid Alarm III (Cleaning Solution)
• Liquid Alarm IV (Optional Solution)
• Temperature Out-of-Range
• Host Serial Port cannot be opened
➢ Fatal Error: an “X”-shape located in the upper, right-hand portion of the System Monitor
mask. It lights up red when activated.
If this red “X” lights up, the operator need simply click on it to access the relative visual text
message explaining the cause of the Fatal Error (said window will open in that area of the mask
dedicated to viewing data).
Following is a list of possible Fatal Error visual text messages:
• Horizontal Arm Error
• Sample Tray Error
• Filter Error
Chapter 09 - ERROR SIGNALING AND TROUBLESHOOTING
Ellipse Service Manual Rev. 03 01 June 2009 Page 3
• ADC Error – Sample Channel
• ADC Error – Reference Channel
• Reaction Tray Position Error
• Plate Error (Home sensor not found)
• Vertical Arm error
• Reagent Tray Error
• Wash System Error
• Diluter Error
• Interlock Open while Instrument is running
• Macro send Error
• Overflow Rx Buffer Micro
• Time out Error (Generic error)
• Invalid command error
• Invalid parameter error
• Check sum error
9.1.2 RESULT FLAGS
Result Flags are categorized under the following group headings, Each group is identified by a
symbol, as listed here-below:
X PHYSICAL ERRORS
R CONCENTRATION ERRORS
C CALIBRATION ERRORS
A OPTIC DENSITY ERRORS
E RESULTS EDITED MANUALLY
? PROGRAMMING ERRORS
Every Result Flag, signalling an error, is accompanied by a symbol representing the group it is
part of. The operator need only click on the small red square ( ) next to the Result Flag symbol
to access the visual text message explaining the cause(s) of the signalled error.
In the central column of the following tables, the user will find those symbols which signal the
type of error encounter, as used in the print-out of the final report. These symbols can be
modified by the operator, in the Parameters section, under print options.
Chapter 09 - ERROR SIGNALING AND TROUBLESHOOTING
Ellipse Service Manual Rev. 03 01 June 2009 Page 4
WARNING! The use of the Error Symbols in the print-out of the results (inclusion and/or
exclusion) IS UNDER THE DIRECT AND SOLE RESPONSIBILITY OF THE USER
9.1.3 DESCRIPTION OF RESULT FLAGS
¾ X Physical Errors
Temperature Error: T Reaction temperature (Reaction Plate) is
out-of-range.
No Sample S Either no sample or sample serum quantity
below minimum or above maximum level
for the declared container.
No Reagent: R Either no reagent or reagent level below
minimum or above maximum level for the
declared container.
No Rack: * No Rack present during sampling.
¾ R Concentration Errors
Very Low and Very High: L-H Flags determined by test results out-of-range as
setup in the Methods.
Low Alert and High Alert: A Flags determined by test results out-of-range as
setup in the Methods.
Low and High Linearity Limit: G Flags determined by test results out-of-range as
Calculation Error: C Concentration calculation error due to
foreseeable causes (Asymptote).
Chapter 09 - ERROR SIGNALING AND TROUBLESHOOTING
Ellipse Service Manual Rev. 03 01 June 2009 Page 5
¾ C Calibration Errors
RBL missing: * No Reagent Blank Level.
Calibration missing: * No Standard or no Calibration curve.
STD Replicate insufficient: * Insufficient number of valid Standard Replicates.
STD Replicate outside CV%: * Coefficient of Variation Percentage in the Standard
Replicates over the set value.
Invalid Calibration: * Calibration curve not valid – either because it is
not monotonic or because the Fit is above the set
value.
¾ A Optic Density Errors
Inversion: I Reaction direction not in line with that set-up.
End Point Limit: P Values over the limits setup in the Methods
Parameters
Depletion Limit: D Values over the limits setup in the Methods
Parameters.
First Limit: * Values over the limits setup in the Methods
Parameters.
FIT: F Values over the limits setup in the Methods
Parameters.
RBL out-of-range: * Reagent Blank Levels outside the range Setup.
Sample outside Standard: # Sample absorbance outside the calibration curve.
Chapter 09 - ERROR SIGNALING AND TROUBLESHOOTING
Ellipse Service Manual Rev. 03 01 June 2009 Page 6
¾ E Results Edited Manually
Results Edited: E This symbol automatically appears whenever the
operator has manually modified the obtained
results. This operation annuls all the symbols
indicating errors which, in this case, will not be
viewed.
¾ ? Programming Errors
All those software errors which are deemed unforeseeable are indicated using this symbol.
¾ Result Asterisks
In the event that the following situations and/or error conditions occur, the system will notify
the user via a visualization of two asterisks (**) in the Results field:
PHYSICAL ERRORS
1 – very little or no sample
2 – very little or no reagent
3 – no rack
CONCENTRATION ERRORS
4 – calculation error
5 – signalling depletion limit
PROGRAMMING ERROR
6 – all cases
In the following situations and/or error conditions, the results field will contain a “0”:
1 – if the result is less than zero
2 – if the result is equal to zero
OPTIC DENSITY ERRORS
3 – Flag signalling inversion

9.2 TROUBLESHOOTING GUIDE
PROBLEM ➢ POSSIBLE CAUSE SOLUTION
Repeatability of results insufficient
➢ Sample Probe dirty
Clean the Sample Probe as described in Chapter 07
Maintenance
➢ Hydraulic leak and/or air bubble in the hydraulic circuit
(sampling)
Check Sample Probe fit
Check the fit of the hydraulic tubes and their connection:
if necessary, substitute the tubes and/or adjust their
connections/fittings
➢ Wash solution is contaminated. If the wash solution
contains contaminating particles (e.g.: mold, dust, lint), these
micro-particles can cause errors during the WBL running.
Change the wash solution
Clean the Wash Solution Bottle(s) and carry out the
Hydraulic Circuit wash procedure as described in
Chapter 07 – Maintenance
➢ Deterioration of the Reagent(s)
Substitute the bad reagent(s)
➢ Reaction cuvettes not dried correctly after being washed
Check the Tip used to dry the cuvettes after washing to
make sure it is in good working condition. If necessary,
clean the Tip or change it, following the procedure
described in Chapter 07 – Maintenance
➢ Light bulb not stable
Light bulb nearing the end of its 2000-hour life cycle
duration, or premature deterioration. In both cases,
change the light bulb following the substitution
procedure described in Chapter 07 – Maintenance.
Insufficient volume/quantity of the
various Rinse, Cleaning and
Distilled Water solutions.
➢ This type of problem can present itself either when the
instrument is first turned on due to a lack of liquid in one or
more bottles, or during test running whenever the involved
liquid has been finished
Refill the required bottle. If the instrument is running
tests, it will automatically Pause. Wait until sampling is
suspended, then refill the involved bottle with the
required liquid (Rinse/Cleaning/ Distilled Water). Press
Start to continue running the rest of the programmed
tests. This operation will not adversely affect the already
run tests.
