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.

Chapter 01 – INTRODUCTION
NOTE: Even though the computers demonstrate the same technical and operative characteristics,
some of these could have different hardware installed.
This could cause problems for the Ellipse software when running tests (A message appears
indicating “Random” error or blocks the program).
Therefore, if the PC is bought separately/locally, it is highly recommended to test the system at
your offices before preceding with the installation at the final client’s.
Consequently, AMS denies any responsibility for software problems that are due to buying the
computer separately from the instrument.

Chapter 02 – SYSTEM DESCRIPTION
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.
Ellipse Service Manual Rev. 03 01 June 2009 Page 2
Chapter 02 – SYSTEM DESCRIPTION
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;
Ellipse Service Manual Rev. 03 01 June 2009 Page 3
Chapter 02 – SYSTEM DESCRIPTION
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.

horizontal sampling arm, Diluter, peristaltic pump;
the Control Panel Board for the three buttons-indicators checking.
Ellipse Service Manual Rev. 03 01 June 2009 Page 9
Chapter 02 – SYSTEM DESCRIPTION
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.

Chapter 02 – SYSTEM DESCRIPTION
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.
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.

3.2 INSTALLATION
The ELLIPSE must only be installed by a qualified technician who has been authorised and
trained to do so. During its installation the system will be checked once again to ensure correct
functioning. The persons who are required to operate the ELLIPSE system must have received
the adequate training. This should also include the "know-how" of the normal maintenance for
the instrument. A description of the maintenance will be found in Chapter 7 of this manual.
ELLIPSE is a complex system, and it is therefore extremely important that it is correctly
installed in order to fully guarantee fine performance. If the installation and use directions,
given in this manual, are not correctly followed and/or security indications are not respected,
AMS cannot guarantee correct functioning of the instrument. Apart from this, the security of
the operator could be placed at risk.
