1 INSTALLATION
1.1 UNPACKING
The SAT450 is packed and delivered in two separate wooden crates: one containing the
analyzer and the other the computer along with its accessories. In the event that the order not
include the PC, packing and delivery will involve one wooden crate plus a corrugated cardboard
box.
This packing modality has been expressly studied and designed to insure maximum protection
of the contents during shipping and handling. It is therefore extremely important that the crates
or crate/box combo be carefully inspected upon delivery in order to ascertain their integrity.
Special attention should be dedicated to examining the color of the ShockWatch ® glued to
the crates: it must be white. A ‘red’ ShockWatch ® indicates that the crate(s) have experienced
some sort of mishandling (shock) during transport and/or delivery. This fact must be recorded by
the courier on the delivery note, as must any and all visible external damage to the packing
crates/box (e.g.: holes, dents, rips or tears, water marks, etc.) evident at the moment of
consignment. This serves to simplify matters in the event of any future claims for damages.

PLEASE NOTE: THE SHIPPER ASSUMES TOTAL RESPONSIBILITY FOR THE CRATES
AND/OR BOX AND THEIR CONTENTS ONCE THE GOODS HAVE LEFT THE
FACTORY UNTIL THE MOMENT THEY ARE CONSIGNED AT DESTINATION.
FURTHERMORE, THE SHIPPER IS RESPONSIBLE FOR ANY AND ALL DAMAGES
ARISING DURING HANDLING, STORAGE AND/OR TRANSPORT. ANY AND ALL
DAMAGE CLAIMS MUST BE TAKEN UP WITH THE SHIPPER IMMEDIATELY
UPON DISCOVERY.
Upon consignment 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/box and that they are undamaged.
Check that the serial number on the delivery
note/packing list corresponds to that
impressed on the plate on the right side of the
instrument.

INSTRUMENT INSTALLATION

The SAT450 instrument must be installed only by authorized, specialized technical personnel.
During instrument installation, the system will be checked once again to make sure that it
functions correctly. The SAT450 is for professional use only; therefore, the operators who use the
instrument (in addition to the academic qualifications and state certification required to meet
government regulations) must be trained in its proper use and this training must also regard
ordinary instrument maintenance practices. Maintenance activities are described in Chapter 7 of
this same manual.
In order to preclude risks of potential biological hazards, it is absolutely necessary that good
practices regarding the handling of biological samples, consumables and waste/refluents be
scrupulously adhered to.
The SAT450 is a complex system and, as such, it is of utmost importance that the installation
procedure be executed correctly in order to guarantee optimum levels of performance. In the event that
the indications reported herein (in this manual) and/or relevant safety norms are not followed, AMS
cannot and does not guarantee proper instrument functioning. Furthermore, user safety may be placed at

DESCRIPTION OF THE SYSTEM

2.1 INTRODUCTION
The SAT450 is a benchtop, fully automatic, random access, open analyzer for clinical and
immunoturbidimetric assays.
It communicates with a computer through a USB and/or RS 232 port.
The SAT450 instrument is composed of the following main parts:
Sampling Arm;
Diluter;
Reactions Plate;
Samples Plate;
Reagents Plate;
Photometer;
Washing Station;
Electronic Boards.

2.2

SAMPLING ARM

One mechanical Arm performs all sampling operations. It is able to reach the aspiration point
of the Reagents Plate, the aspiration point of the Samples Plate, the delivery point of the
Reactions Plate and the two Washing Wells.
A specific sampling Probe is connected on its head (compare the scheme MA-15-02339-00).
The Sampling Arm can move vertically and horizontally with respect to the Raising Top of the
instrument by means of two stepper motors, respectively. The horizontally movement take place
along a arch of circumference.
A Pre-Heater Assy allows a reagent pre-warming at 37.0 °C. Moreover, one Level Sensor
Board - opportunely connected to the Sampling Probe - allows a liquid level (capacitive) sensing.

2.3

DILUTER

The Diluter allows to perform all the operations of aspiration and delivery of the liquid up till
the capacity of 1000 µl. It is connected to the Sampling Arm and to its electrovalve and
micropump as showed in the scheme MA-15-02339-00. It is able to sample volumes of 0.25 µl,
with a CV less than 1%.
The device is actioned through the movement of a unique central piston for the operations of
aspiration and delivery of the liquid. The piston is moved through a stepper motor without use of
step-down gears to minimize the backlash. Moreover, in this device are implemented some
solutions to avoid the presence of air microbubble inside it and inside the hydraulic circuit.

SAT450

Service Manual

Rev.00

03 July 2008

Page 2

Chapter 02 – SYSTEM DESCRIPTION

2.4 REACTIONS PLATE
The Reactions Plate of the instrument contains 4 disposable racks with 20 reaction cuvettes each,
for a total of 80 cuvettes. Each of them has a optical path of 6 mm. The reactions racks can be
removed individually. The plate is covered by a specific plate cover.
The plate can rotate through a stepper motor (compare the scheme MA-15-02353-00). This motor
assures a high precision of positioning, superior to ± 0.1°.
The basic operating cycle includes: aspiration and dispensing of the reagents and the samples by
the Sampling Arm in the reaction cuvettes, optic reading of the cuvettes in incubation by the
Photometer - along with the relative positioning of the Reactions Plate -, washing of the filled
cuvettes by a Washing Station.
The incubation temperature in the reactions cuvettes is controlled at 37° C ± 0.3 by a controlled
heating unit (Reactions Plate Resistor) placed inside the Reactions Plate .

2.5 SAMPLES PLATE
The Samples Plate is composed from a main plate that revolves around its axis and from the four
Satellite Racks (“A”, “B”, “C” and “D”) which, each of them, revolve at the same time around to
own axis. Therefore, the Samples Plate is apt to describe a substantially hypocycloidal motion.
The main plate can rotate through a stepper motor, whereas the four Satellite Racks can rotate
through another stepper motor (compare the scheme MA-15-02338-00). This two motors assure a
high precision of positioning. The two different rotations are controlled through the respective
Home Sensors.
The four separate Satellite Racks (“A”, “B”, “C” and “D”) are universal racks for continuous
loading of samples, calibrators and controls. Each Satellite Rack contains up to 15 cups and/or tubes
with 10÷16 mm of diameter and 40÷100 mm of height. Moreover, 8 extra positions - for the same
cups and/or tubes - are positioned on the main plate for urgent samples, calibrators and controls.
The Samples Plate is covered by means of two covers: Samples Plate cover and Samples Plate
safety protection. Removing only the Samples Plate safety protection allows the replacement of the
Satellite Racks for continuous loading. A urgent sample execution is allowed at any time.

2.6 REAGENTS PLATE
The Reagents Plate is composed from a main plate that revolves around its axis and from the four
Satellite Racks (“A”, “B”, “C” and “D”) which, each of them, revolve at the same time around to
own axis. Therefore, the Reagents Plate is apt to describe a substantially hypocycloidal motion.
The main plate can rotate through a stepper motor, whereas the four Satellite Racks can rotate
through another stepper motor (compare the scheme MA-15-02348-00). This two motors assure a
high precision of positioning. The two different rotations are controlled through the respective
Home Sensors.
Each of four removable universal racks (“A”, “B”, “C” and “D”) contains 4 positions for rounded
bottles of 10/20 ml and 4 positions for trapezoidal bottles of 50 ml. Each of four trapezoidal bottles
of 50 ml can be substituted with two trapezoidal bottles of 25 ml or, by a adaptor, with one rounded
bottle of 10/20 ml or with one squared bottle of 17 ml. Moreover, 8 extra positions for rounded

SAT450

Service Manual

Rev.00

03 July 2008

Page 3

Chapter 02 – SYSTEM DESCRIPTION

bottles of 10/20 ml are positioned on the main plate. Each of eight rounded bottles of 10/20 ml can
be substituted, by a adaptor, with one cup of 2 ml.
All the bottles inside the Reagents Plate are cooled by four Cooler Modules positioned on its
border. Each module is composed from two Peltier cells and two fans (as showed in the scheme
MA-10-02536-XX) opportunely powered. One of them has a Cooler Temperature Sensor in order to
control the refrigeration temperature.
The plate is covered by a specific plate cover.

2.7

PHOTOMETER

The Photometer allows the direct reading of the Optic Density (O.D.) of the reaction that take
place in any cuvette of the Reactions Plate.
The device is composed from two reading channels: Sample Channel for the direct reading of the
O.D. value and Reference Channel for its reference value. Each of them is provided of a
Pre-Ampl./ADC board for the conversion in a digital signal of the light beam that pass through the
cuvette.
The light source is a halogen lamp (6V/10W). It is powered by a Photometer Lamp Board.
The device contains a Filters Wheel for the reading of the reaction at different wavelengths. The
wavelengths of the 9 narrow band interferential filters placed on the wheel are the following:
340 nm, 380 nm, 405 nm, 492 nm, 510 nm, 546 nm, 577 nm, 620 nm and 690 nm. Moreover, the
Filters Wheel has a dark position (compare the scheme MA-15-02448-00).
The Filters Wheel can rotate through a stepper motor. The selection of the exact reading filter
is controlled by means of the Filters Wheel Home Sensor and its reference on the wheel.

2.8 WASHING STATION
The Washing Station allows the washing operations of the Reactions Plate cuvettes.
The Washing Station is made up of a series of five small probes (compare the scheme
MA-10-02181-00). It is situated on a part of the Reactions Plate and each probe can goes down into
a single cuvette.
This said five probes are opportunely connected to the washing station electrovalves and
micropumps (as showed in the hydraulic diagram SI-16-01873-00) for the emptying, washing and
drying operations of the cuvettes. In particular, the last probe has a pad for the drying operations.
The vertical movement of the Washing Station on the Reactions Plate is allowed by its
leadscrew connected to a stepper motor.

2.9 ELECTRONIC BOARDS
2.9.1 Introduction
The Electronic Diagram of the SAT450 instrument is reported on the document having the code
SC-16-01873-XX. This scheme shows all the electronic boards of the instrument and the electric
interconnessions between them.
The power supply is connected through a input line to the power grid (90 ÷ 250 VAC,
47 ÷ 63 Hz), whereas through a dedicated wiring to the electronic boards. The power supply has
three output voltage modules: + 24 V, + 12 V and + 8 V (as showed in the scheme MA-46-02636-00).

1. Make sure that the SAT450 instrument is turned off.
2. Dampen the gauze or the paper towel with distilled water and clean the outside of the
Sampling Probe. Note: wipe the Probe from the top downwards only! This is to avoid that
any bits of cloth, paper or lint fibres accidentally enter inside the Probe.
It is suggested that once weekly the above described cleaning procedure must be performed
using a 5% sodium hypochlorite solution instead of distilled water to dampen the gauze or
the paper towel. Then, repeat the procedure using distilled water.

6.3

WASHING STATION PROBES – Cleaning procedure
Use only lint free paper towel or gauze.
1. Make sure that the SAT450 instrument is turned off.
2. Place a sheet of paper under the Washing Station probes in order to keep any extraneous
material from accidentally downfall into the reaction cuvettes.
3. Dampen the gauze or the paper towel with distilled water and clean the outside of the probes
(with the exception of the last probe). Note: wipe the probes from the top downwards only!
This is to avoid that any bits of cloth, paper or lint fibres accidentally enter inside the probes.
4. Remove the sheet of paper from under the Washing Station probes.
It is suggested that once monthly the above described cleaning procedure must be performed
using a 5% sodium hypochlorite solution instead of distilled water to dampen the gauze or the
paper towel. Then, repeat the procedure using distilled water.

6.4

FOUR LIQUID RESERVOIR BOTTLES – Cleaning procedure
During a normal use and over time, mold and dust can build up inside the four liquid
reservoir bottles. For this reason, it is extremely important that they be periodically washed.
The 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, it is recommended to make 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 four liquid reservoir bottles are located on the side of the instrument inside their
container.

SAT450

Service Manual

Rev. 00

laboratory’s quality control values.

6.5

DRYING PAD – Cleaning procedure

The Pad is used to dry the cuvettes after they have been washed. This drying process is carried
out via aspiration and therefore, over time, the Pad will necessarily absorb various contaminating
particles.
It is suggested that the Pad 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 Pad must be washed regularly in order to guarantee proper functioning and must be
replaced - if necessary - with a new Pad.

Cleaning procedure for the Pad:
1. Make sure that the SAT450 instrument is turned off.
2. Unscrew the fastening screw of the Washing Station cover and remove the cover from its
place on the Raising Top.
3. Unscrew the four fastening screws of the Washing Station tubes cover and remove the

6.7

HYDRAULIC CIRCUIT – Washing procedure

During normal use and over time, mold and dust can build up inside the bottles and can have a
negative effect on the hydraulic circuit, compromising the correct functioning of the micropumps
and electrovalves. 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. It is recommended to make 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 straws are located inside the liquid reservoir bottles on the side of
the instrument.

Washing procedure for the Hydraulic Circuit:
1. Make sure that the SAT450 instrument is turned on.
2. Prepare a bottle containing 500 ml of a 5% sodium hypochlorite solution.
3. Insert the four aspiration straws, located inside the liquid reservoir bottles, into the
bottle containing the sodium hypochlorite solution.
4. Carry out a ‘WBL’ cycle and then a ‘Washing cuvettes’ cycle.
5. Wait for fifteen minutes. Clean and dry the four straws and then insert them into a bottle
containing distilled water.
6. Carry out a ‘WBL’ cycle and then a ‘Washing cuvettes’ cycle.
7. Insert the four aspiration straws back into their respective bottles. In the meantime, said
bottles should have been cleaned and filled with a fresh supply of the required solution.
8. Carry out a ‘Washing cuvettes’ cycle and then a ‘WBL’ cycle. Check the system
efficiency by comparing the WBL values and the test results obtained against the
laboratory’s quality control values.

6.8

REPLACEMENT OF THE PHOTOMETER HALOGEN LAMP
It is suggested that the halogen lamp be replaced after approximately 2000 hours of use.

The halogen lamp is mounted on the Photometer, which is located on the side of the Reactions
Plate.
Replace the Photometer Halogen Lamp performing the relative procedure described into
the Section 6.4.5 (Chapter 06).

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 program is the following: "9600, N, 8, 1".

Chapter 07 – Host Communication

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.
•

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 program 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.

ERROR SIGNALING AND TROUBLESHOOTING

8.1 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.

8.1.1

SYSTEM ERRORS

Whenever a system error is detected, it is signalled via the activation of the below listed
warning lights/buttons:
o Warning Light: a triangle-shape located in the System Monitor screen. It lights up yellow
when activated.
If this yellow triangle lights up, the operator needs simply to 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
• Liquid Alarm II
• Liquid Alarm III
• Liquid Alarm IV
• Temperature Out-of-Range
• Host Serial Port cannot be opened
o Fatal Error: an “X”-shape located in the System Monitor mask. It lights up red when
activated.
If this red “X” lights up, the operator needs simply to click on it to access the relative visual
text message explaining the cause of the Fatal Error (said window will open in that area
dedicated to viewing data).
Following is a list of possible Fatal Error visual text messages:
• Arm Error
• Filters Error
• ADC Error – Sample Channel
• ADC Error – Reference Channel
• Plates Error (home sensor not found)
• Washing System Error
• Diluter Error
• Interlock Open while Instrument is running

8.1.2

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 pertinent
group. The operator needs simply to 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 encountered, as used in the print-out of the final report. These symbols can be
modified by the operator in the “Print Options” form of the “Parameters” section.

Note

8.1.2.1

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.

DESCRIPTION OF THE RESULT FLAGS

TROUBLESHOOTING GUIDE
➢ POSSIBLE CAUSE

PROBLEM

SOLUTION
➢ Sampling Probe dirty.
Clean the Sampling Probe.
➢ Hydraulic leak and/or air bubbles in the hydraulic circuit.
Check the Sampling Probe fit.
Check the fit of the hydraulic tubes and their connection: if
necessary, substitute the tubes and/or adjust their
connections/fittings.

Insufficient
repeatability of results

➢ Wash solution is contaminated. If the wash solution contains
contaminating particles (e.g.: mold, dust, lint), these microparticles can cause errors during the WBL running.
Change the wash solution.
Clean the liquid reservoir bottle(s) and carry out the Hydraulic
Circuit washing procedure.
➢ Deterioration of the Reagent(s).
Substitute the bad Reagent(s).
➢ Reaction cuvettes not dried correctly after being washed.
Check the Pad used to dry the cuvettes after washing to make
sure it is in good working condition. If necessary, clean the
Pad or change it, following the relative procedure.
➢ Halogen lamp not stable.
Halogen lamp nearing the end of its life cycle (2000 hours), or
premature deterioration. In both cases, change the Halogen
Lamp following the replacement procedure.

Insufficient
volume/quantity
of the various solutions

SAT450

➢ This type of problem can present either when there is a lack of
liquid in one/more bottle(s) or - during the test running - when
the involved liquid has been finished.
Refill the involved bottle(s). If the instrument is running tests,
it will go automatically in “Pause”. Wait until sampling is
suspended, then refill the involved bottle(s) with the required
liquid(s). Press Start to run the rest of the programmed tests.
