The physical layer is used to transfer bytes between target and host. This is achieved by meansof an RS232 interface. The target is supplied via a 9-pins DB9 male connector. The connectionsare shown in the following table:
Pin Signal In/Out(from point of view of the Target)
1 DCD In
2 Rx In
3 Tx Out
4 DTR Out
5 GND -
6 DSR In
7 RTS Out
8 CTS In
9 RI In
Table 1: Pinning of the Host DB9 male connector
Only the Rx and Tx signals are used to transfer bytes between target and host. There will be nohardware handshaking between target and host.
The baud rate is fixed at 9600 Baud. Bytes are transferred with 1 start bit, 8 data bits, 1 stop bitand no parity bit.
In order to connect a PC Host to the target, a simple NULL-modem (crossed Rx/Tx signals) ca-ble is sufficient.
The signal levels comply with the RS232 specification. The cable length between Target andHost is specified as being less then 10 meters.

A.1.2 Packet layer
The packet layer offers reliable and error-free packet transfer across the connection. It imple-ments error detection and recovery on packet level, so the message layer is assured that pack-ets sent reach the other side without corruption, and also that incoming packets are not cor-rupted.
A packet consists of a number of bytes. Its format is:
Header(1 byte 0xFF)
Length(1 byte)
Type(3 bits)
ID(5 bits)
Data(n bytes)
Checksum(1 byte)
The Header byte is defined as hexadecimal value 0xFF. The next field consists of a byte indi-cating the number of bytes in this packet after the length field, including the checksum byte.This defines the maximum packet size to 257 bytes. The Data field is at most 253 bytes.
The type field indicates the contents of the packet. This is either:
Type bits Description
000 data packet containing n bytes of message data in the Data field.
001 ACK packet, acknowledging a previously received data packet. The Data field isempty.
010 NACK packet, indicating an error in a previously received data packet. The Datafield is empty.
011 Heartbeat Request packet, used for communication status polling. The Data fieldis empty.
100 Heartbeat Acknowledge packet, used for communication status polling. The Datafield is empty.
101 Reserved. Do not send a packet with this type. Ignore received packets with thistype.
110 Reserved. Do not send a packet with this type. Ignore received packets with thistype.
111 Reserved. Do not send a packet with this type. Ignore received packets with thistype.
Table 2: Packet Type field definition
The ID is a modulo 32 number identifying a data packet. This is used on the target side to noticemultiple transmissions of the same data packet. In case of ACK or NACK, the ID field is set to 0.
If a packet is a data packet, n bytes of data reside in the data field. The number of bytes of thedata field is calculated as: n = Length - 2
If it’s an ACK or NACK packet, the Data field is empty.
Finally, a checksum byte is added. The checksum is a modulo 256 addition of all packet bytesfollowing the header byte till the checksum byte, subtracted from 256. Therefore, the sum of allbytes following the header including the checksum byte must be zero.

The following tables show the usage of the packet protocol under several conditions:
A: The data packet #0 is received correctly at the target, and the ACK is received correctly atthe host.
B: The data packet #1 is corrupted, so a NACK is returned. The host responds with a retry,which works correctly.
C: The host sends a data packet #2, but it never reaches the target. After a time-out period, ifstill no ACK or NACK has been received, the host does a retry.
D: A data packet #4 is received correctly at the target, which responds with an ACK. However,the ACK doesn't reach the host or becomes corrupted. After a time-out period, the hostresponds with a retry of data packet #3. The target receives another data packet #3, whichis not sent to higher level software because it already received a correct data packet #3.The receiving is acknowledged to the target, though.
When a value 0xFF within a packet is falsely seen as a packet header, the packet Layer will re-cover from this error by means of the packet timeout or a checksum failure: The receiver ex-pects a number of bytes determined by the byte received after the 0xFF. If the receiver expectstoo many bytes, a packet timeout will occur after the sender has sent the last byte of the packet.If the receiver expects the exact amount or less bytes than the remaining bytes in the currentpacket, a checksum failure occurs, and the receiver will wait for the next packet header.
A number of parameters must be determined:
Packet time-out: This is the maximum time between the first bytes of a packet (0xFF)and the last byte of a packet. The receiver starts a timer when theheader byte is received. The complete package must be receivedbefore expiration of the timer. If the timer expires before packetcompletion, a packet time-out has occurred and another start-of-packet is awaited. (The bytes received so far are ignored.)
The value chosen for the packet time-out is 1 second.
This mechanism will prevent a system lock-up when the serial con-nection is lost in the middle of a packet transfer. reported to highersoftware levels.
Ack/Nack time-out: This is the maximum time that is waited for an ACK or NACK packetafter sending a data packet. If after this time no ACK or NACK isreceived, a retry is performed. The value chosen for the Ack/Nacktime-out is 2 seconds.
Packet maximum retries: This is the maximum number of consecutive retries for sendingpackets. If this number is exceeded, a communication error isreported to the message layer.
The maximum number of packet retries is set to 5.

A.1.2.1 Heartbeat mechanism
The packet layer on the target will implement a mechanism to detect the availability of a logicalconnection to a packet layer on a host. It will do so by sending ‘heartbeat request’ packages ata certain time interval (Heartbeat Frequency). A packet layer on the host must respond within acertain timeout (Heartbeat Timeout) with a ‘heartbeat acknowledge’ packet. If the host respondsin time, the logical connection is available. If no response is received, or not in time, a logicalconnection is not available.
The Heartbeat Frequency is set to ‘one heartbeat per seconds’. The Heartbeat Timeout is set to5 seconds.
A host can use the same mechanism to detect the availability of the target.
The host is also allowed to send a ‘heartbeat request’ package to the host in order to detect thepresence of the target. The target will respond with a ‘heartbeat acknowledge’ as soon as it re-ceives a request.

A.1.3 Message layer
The message layer provides a way for the application layer to send and receive messages ofrandom length. The message layer cuts outgoing messages into packets and sends themacross the connection by means of the packet layer. The message layer concatenates incomingpackets to form a complete message. This is shown in Figure 4.
Figure 4: Message to multiple packet transformation
The target is capable of receiving a message that consists of 1 packet maximum. This sets themaximum message size to 252 bytes. This is sufficient for all the application messages used bythe target.
A 1 byte header is added to the message data in a packet before it is sent. This header indi-cates if it is the first packet, an intermediate packet or the last packet of the message. While re-ceiving messages, this information is used to detect start and finish of the message.
Header definition:
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Reserved Reserved Reserved Reserved Reserved Reserved Lastpacket ofmessage
Firstpacket ofmessage
If a message fits into one packet, this will be both the first and last packet of the message. Apacket is an intermediate packet when neither of the two bits is set. The reserved bits must beset to 0 when a packet is sent.
If transmission of one of the packets fails (even after retries), the transfer of the message isaborted and an error reported to the application layer. (The message layer does not performretries, since a retry-mechanism is available on the packet layer.)

A.1.4 Application layer
The application layer sends and receives application messages through the message layer. Onthe application layer level, the FUMO acts as a slave to the host. It will not autonomously sendapplication messages to the host. It will only send application messages in response to applica-tion messages from the host. (The one exception is the HOS_setStatus message that is sent tothe FUMO whenever the state of the FUMO changes and when it is subscribed.)

The sticker [B] shows the temperature offset of the temp. sensor. It has a total of 5 positions.Example: +0.50, including the decimal point. The offset can be positive (+) or negative (-). Thevalue is in degrees centigrade °C. The Offset is the deviation from 37.0 °C.
Temperature reference sensor is 37.0 °C.If sensor (to be calibrated) indicates 36.5 °C then the offset value is -0.50 °C.If sensor (to be calibrated) indicates 37.3 °C then the offset value is +0.30 °C.
The system needs to be set as follows:If the offset is “-“, the minus sign and the offset value must be entered in the system.If the offset is “+“, only the offset value must be entered in the system, not the plus “+” sign.

1 Safety Precautions and Potential Hazards
1 - 2 Service Manual – Micro Series V. 1.00
1.1 General
Before you start installing and working with the analyser, you should read the safety precautionsand regulations detailed in this chapter. Safety comes first!
1.2 Operator Qualifications
− Operation should be conducted under the management of a technician who has undergonetraining at the facility specified by the sales agent.
− For clinical tests, the instrument should be used under the management of a doctor orclinical inspector.
1.3 Service Technician Qualifications
To install, maintain and repair the instrument, a service technician has to be trained in the useof the instrument by the manufacturer or their representative. A service technician is also ex-pected to be familiar with the normal operation of the instrument as described in the User’sManual and the special operations as described in the Service Manual.
1.4 Description of Symbols
Symbols on the instrument
This symbol means that the labelled item is hot while the instrument is in use. Do not touch thelabelled item as you could be burnt!
This means that the labelled item could lead to personal injury and/or damage to the analyser.
Note
Notes contain additional information corresponding to the text.
Safety Precautions and Potential Hazards 1
Service Manual – Micro Series V. 1.00 1 - 3
1.5 Electrical
Please pay attention to the following items:
− To prevent the risk of electrical shock and/or damage to the instrument Operators shouldnot open the top cover of the instrument. Only authorised personnel, for example, servicetechnicians, may open the instrument to perform maintenance or repair.
− Don't touch the main board when the power is on as this may cause severe injury or death.
1.6 Mechanical
There is no risk presented by the mechanical parts of the instrument when both the covers areclosed. If the covers of the instrument are removed, mechanical parts could cause personal in-jury if touched or become damaged. Therefore, the following advice must be followed: DO NOTwear loose garments or jewellery that could catch in mechanisms. DO NOT put your fingers/hands into the path of any part while the analyser is in operation. DO NOT attempt to make me-chanical repairs unless the instrument is not in operation or turned OFF.
1.7 Lamp
During operation, the photometric lamp becomes extremely hot. DO NOT look directly into thelight path of the lamp when it is on. DO NOT touch the lamp when it is on!
If the lamp needs to be changed, always turn off the lamp by switching off the instrument andthen wait until the lamp has cooled down.
1.8 Chemical
The operator is responsible for taking all necessary precautions against hazards associatedwith the use of clinical laboratory chemicals. Specific recommendations for each reagent usedwith the analyser are normally found on the manufacturer's package inserts or on product infor-mation sheets for each chemical. Wipe away any reagent spillage on the instrument immedi-ately.
1 Safety Precautions and Potential Hazards
1 - 4 Service Manual – Micro Series V. 1.00
1.9 Biohazardous Materials
As with all in vitro diagnostic equipment, patient samples and serum-based quality control (QC)products that are assayed on this system, as well as all waste from the waste container, shouldbe treated as potentially biohazardous. All materials and mechanical components associatedwith the sampling and waste system should be handled according to your facility's biohazardprocedure.

The Micro Series is a software-controlled system for clinical chemistry. It is designed for bothquantitative and qualitative in vitro determinations using a wide variety of tests for the analysisof serum and plasma.
Micro Series analysers are capable of meeting all the manual or discrete requests of the clinicallaboratory. The instrument has been designed with great flexibility to cater for the urgent de-mands of the medical as well as the laboratory staff. State of the art technology and advanceduser-friendly software meet the individual requirements of each clinical laboratory.
The analyser is a small, compact instrument and comprises the analyser unit and the computerunit with a fully integrated screen and keyboard, which boasts most of the normal keys of acomputer keyboard. Last but not least, an integrated printer prints out results and statistical in-formation.
The instrument can be placed on a bench top; thus saving space in the laboratory environment.For easy operation, the most frequently used test parameters are pre-programmed so that theoperator needs only to select the test and then immediately start the analysis. User-definedtests can be entered easily using the comfortable integrated keyboard. An external standardcomputer keyboard can be connected if required.
The software provides calibration and control measurements, up to 60 pre-programmed tests,user-defined tests, result statistics and reports.
Data transmission to and from the analyser is achieved through the serial port of the instrument.Furthermore, the parallel port of the instrument enables the management of data between aconnected laboratory electronic data processing system (Lab-EDP).

5.1 Overview
The analyser is a compact, state of the art instrument with a straightforward design. It has beenengineered with a precise simplicity to ensure a high level of reliability.
Ease of maintenance and fast troubleshooting were taken into consideration during the designphase. The result is that all components selected were, where possible, from the manufacturer's'off-the shelf' stock. Should a component fail, it can easily be replaced by Vital.
The units have been designed for plug-in replacement of circuit boards and major mechanicalassemblies that permit on-site repair; thus ensuring an absolute minimum of instrument down-time.
In order to support the service technician, comprehensive test, diagnostic and alignment proce-dures have been included in the software.
5.2 Mechanical Design
The analyser consists of two major assemblies:
The baseplate assembly containing:
− Optical system
− Fluid system
− Processor board
− LCD display
− Printer.
The cover assembly containing:
− Top cover with keyboard
− Service cover.

5.4 Optical System
As shown in the diagram below, the light source consists of a special, long-life 12 V / 20 Whalogen lamp. The detector consists of a UV-enhanced silicone photocell.
Note
Only use an original spare part lamps. Ordinary lamps often have UV-blocking glass thatcauses the analyser to malfunction when measuring at 340 Nm.
The optical design has been kept as simple as possible.
The filament of the lamp is projected into the lens in front of the flow cell, whilst the diaphragm isprojected just after the flowcell, creating a parallel beam in the flowcell.
Monochromatic light is achieved by using single IFL filters (interference line). The filters aremounted in a stepper motor driven, 12-position filterwheel. Depending on the test being carriedout, the microcontroller will automatically set the filterwheel to the correct position as instructedby the software.
For the high wavelength range, a filter with a low transmittance is used to level out differencesin energy at the low and high ends of the spectral range. This is necessary because the emis-sion of the quartz iodine lamp and the spectral response of the detector are both much higher inthe visible and near infrared range than the near ultra-violet range.
The lamp can be adjusted to optimise alignment for light via an arched adjustment range (seechapter 7, "Maintenance"). A set-screw is used to lock the lamp into position.

5.5 Fluid System
The fluid system consists of three major components:
− Flowcell
− Valve bracket assembly
− Bellows pump.
There are two major flow cycles, the Aspirate cycle and the Waste cycle.
During the Aspirate cycle, the inlet valve is open and the outlet valve is closed. The bellows ofthe bellows pump move downwards. Fluid is then aspirated through the sipper tube, the flow-cell, and the inlet valve to the inlet of the bellows pump. The bellows pump stops when the pro-grammed volume has been reached.
During the Waste cycle, the inlet valve is closed and the outlet valve is open. The bellows of thebellows pump move upwards. Fluid is transported via the outlet of the bellows pump through theoutlet valve to the waste outlet at the rear of the instrument.
5 Physical Description of the Instrument

VIT
AL
SC
IEN
TIF
IC N
.V.
The bellows pump is designed in such a manner that the fluid always flows in one directionthrough the bellows pump to prevent clotting of the fluid.
The bellows pump is software controlled. When the instrument is switched on, the bellows moveupwards until they reach their zero position, which is determined by an optocoupler. They thenmove downwards a little to a position that is registered as "zero". This means that during theaspirate cycle the bellows will move downward from this position and during the Waste cycle,upward as far as this position. When reset, the bellows return to the "zero" position.
The flowcell is made of stainless steel and has two connection pipes. The lower connection pipeis for the sipper tube (Teflon) and the upper, for the waste tube (silicone). The light-path of theflowcell is 10 mm and on both sides are sealed quartz windows. A Peltier element is used fortemperature control of the flow cell. A temperature sensor is mounted on a small photometerboard and is pressed into a hole in the flowcell.
Note
Cleaning instructions in the Operator's Manual must be observed for correct functioning of thesystem and to ensure "bubble-free" filling of the flowcell.

5.6 Description of Function
This section provides some general information on the architecture of the analyser withoutgoing into detail of the electronic design.
5.6.1 System organisation and data structure
The microcontroller is responsible for overall functional control of the analyser. The programfor the microcontroller is stored in flash memory with a total storage capacity of 2 Mbyte.
The system data memory is a non-volatile 512 Kbytes static CMOS RAM. A lithium battery,which is used as the back-up power source, will maintain the data for a period of at least4 years after the instrument has been switched off.
The I/O structure of the system has been designed as a memory-mapped I/O. In such a struc-ture, peripheral devices and functional circuits controlled by the microcontroller are part of thememory.
The interfaces between driver devices are controlled via I/O ports of the controller and via an insystem circuit programmable logic device.
The LCD is controlled by an Epson SED 1335 LCD controller. The internal printer is controlledby an Epson LA180 controller. The RS 232 C serial interface is controlled by the UART of theC 167 controller.
5.6.2 Signal processing
The microcontroller can collect data at a rate of 40 measurements per second. From these 40measurements, 20 are actual measurements derived from the sample currently in process. Theother 20 are subsequent measurements derived from a fixed reference source. Each of thesereference values is used to compensate the subsequent measurement value for deviations inthe system.
The photometer board can, for descriptive purposes, be divided into two stages:
− Programmable input amplifier
− Vlin / Tlog converter (logarithmic A/D converter).
The first stage is an amplifier that has the UV-enhanced silicone photo-diode as an inputsource. The gain of this amplifier is software controlled and depends on the setting of four elec-tronic analogue switches controlled via the I/O lines of the controller. The gain equals the powerof 1.5 and can be programmed in 16 steps, from 1.50, which will produce a gain of 1 to 1.515,which will result in a gain of 438. The gain factor of 1.5 corresponds to an absorbance changeof 176 mAbs (log 1.5 = 0.176).

5 - 8 Service Manual – Micro Series V. 1.00
VIT
AL
SC
IEN
TIF
IC N
.V.
The output voltage from the programmable amplifier corresponds to the relative transmittance.
According to the law of Lambert Beer, the concentration/activity has a linear relation to the ab-sorbance. Therefore the linear output voltage must be logarithmically converted in order to ob-tain the required absorbance from which the significant concentration/activity can be calculated.
The concentration is achieved by utilising the logarithmic discharge curve of a capacitor. Thetime, from the beginning of the discharge until the voltages from the input amplifier and the ca-pacitor are equal, corresponds to the log of the measuring signal.
To eliminate errors caused by the temperature sensitivity of the circuit, a reference measure-ment is performed on a fixed precision voltage source with a nominal value after conversion oflog 101 = 2.0043 Abs.
The discharge time is measured by starting a counter the instant the actual discharge is acti-vated. The counter will be stopped the moment both voltages are equal (measuring voltage andcapacitor voltage) The microcontroller controls the start of the counting and an accurate com-parator determines the point where to stop (end of conversion).
Starting and stopping the input value of the logarithmic curve, as well as selection of the inputvalue for the conversion, (detector or reference signal) is performed by electronic analogueswitches controlled by the microcontroller.
The microcontroller is fed with a timer/counter that receives input from the system clock with aprescaler. At "end of conversion", the timer/counter contains the absorbance value of the sam-ple in process or the reference value.
Every single measuring value is compensated by using the subsequent reference value ac-cording to the following calculations:
nominal referenceRelative measuring value = measured value X
actual reference
The result of this calibration gives the absorbance value in units of 0.1 mAbs. However, the ab-sorbance thus obtained is a relative value and must be corrected with a so-called "AbsorbanceOffset" value in order to find the absolute absorbance. The offset value is obtained during theautomatic blank procedure.
When the automatic blank procedure is started, the microcontroller will perform a series of ac-tions to determine the optimum gain factor for the programmable input amplifier. The gain iscontrolled in such a way, that the output voltage of the amplifier produces an absorbance valuewhich fits within a specific window.
The absorbance thus obtained is referred to as "Absorbance Offset". Once determined it ismemorised by the processor and subtracted from all following measuring values. When a rea-gent blank is measured, this value is also subtracted from all following values. The actual gainsetting is performed by utilising a method of successive approach commonly used in A/D con-verter technology.

5.6.3 Temperature control
Temperature control of the flowcell has been achieved by means of a small Peltier elementmounted beside the flowcell.
Temperature sensing is performed by a smart temperature sensor, mounted in a hole in theflowcell. The sensor is a three-terminal integrated temperature sensor with a duty-cycle output.Two terminals are used for the power, with the third being used to carry the output signal.
The output signal from the sensor is fed to a timer/counter input of the microcontroller. Themicrocontroller verifies, via software, if the temperature is within range of 37 °C, +/- 0.2 °C.
If the set temperature of 37 °C is not reached within 30 seconds a temperature error will occur.
5.6.4 Testing and diagnostic routines
To support the technician, a number of test, diagnostic and alignment procedures have been in-cluded in the software.
Every time power is applied to instrument, the microcontroller automatically performs a power-on test. This test includes a check of all internal memory and when an error is detected, a con-tinuous or intermittent audio alarm will sound.
The service menu provides access to several dedicated test routines by means of which variousparts of the system can be checked and or adjusted. Please refer to chapter 8, "Tests andDiagnostic Procedures".
Note
The service engineer should refer to chapter 10, "Maintenance" in the User’s Manual for half-daily and daily maintenance procedures that are to be carried out by the user.

6.4 Integrated Photometer Board
This board is mounted vertically behind the optical block and contains only the opto-switches forthe filterwheel (reset position) and to detect if the prime lever is activated. This board has beendesigned to reduce the light coming from the lamp.
Signal conversion principle
The amount of light falling on the photodiodedepends on the light energy from the lamp,the transmission of the chosen filter and thetransmission of the sample in the tube. Tocapture the range of light, an input amplifierwith a programmable gain has been chosen.
The principle diagram of the input amplifier is illustrated in the diagram above. An amplificationwith a so-called 'feedback tee' with different resistors in the tee network has been chosen inorder to make the input amplifier programmable. The gain difference (per step) is equal to thepower of 1.5 and can be programmed in 16 steps from 1.50 = 1 to 1.515 = 438. Changing theamplification by 1 step will cause an ΔAbs. of log 1.5 = 0.176. At the minimum diode current, theoutput voltage of the input amplifier must be at least 10 Volt at gain 0. The feedback resistor canbe calculated with both input current and output voltage. At gain 8, a higher feedback resistorwill be switched into the feedback network. A high resistance feedback resistor is much betterthan a low resistor in a tee network.

The analogue to digital conversion from the signal behind the input amplifier is achieved with asingle-slope logarithmic A/D converter, diagram above. The essential parts of the converter arethe logarithmic slope generator, the comparator, the reference voltage and the digital logic. Thetotal conversion consists of two parts, the REFERENCE measurement and the SIGNALmeasurement, see diagram below. One input of the comparator input is connected to thelogarithmic slope generator and the other input of the comparator is connected via S2 to areference of 10 / 100 Volt. With the CHARGE pulse, switch S1 is closed and the capacitor C ofthe logarithmic slope generator is charged with a voltage of 10 Volt, at the same time the binarycounter is reset to zero. When the CHARGE pulse is low the switch S1 is open and the chargedcapacitor C discharges via resistor R. The output of the comparator is high, allowing clockpulses through the NAND gate to the counter. As soon as the logarithmic voltage curve crossesthe reference voltage Uref, the comparator output will go low inhibiting clock pulses to thecounter. The counter value REF-CNT represents the value log 100 = 2.0000. For the signalmeasurement, switch S2 is set to the output of the input amplifier. The conversion of the signaloccurs in the same manner as the conversion of the reference. The counter value SIGNAL-CNTnow represents the amplified photodiode current.
A relative value for the photodiode current is calculated with the following formula:
SIGNAL-MEAS = SIGNAL-CNT x 2.0000 / REF-CNT

8.1 Overview
This chapter contains information concerning the comprehensive test, diagnostic and alignmentprocedures included in the software of the analyser. These are designed to ensure the efficientrunning of the system and support the service technician in carrying out maintenance and trou-bleshooting tasks.
8.2 Power On Check
Each time power is applied to instrument, the microprocessor automatically performs a power-on test to check the correct functioning of the microprocessor and system memory. This test in-cludes a check of internal memory. The analyser checks the correct functioning of the RAMmemory by writing certain data and reading it. The flash memories are tested by a checksumtest. When an error is detected, a continuous or intermittent audio alarm will sound. When eve-rything goes well one 'beep' is heard during the start-up of the Micro Series.
8.2.1 RAM test
A series of tests is performed to determine whether or not the writing and reading of data toRAM functions properly:
− The first test checks if the data line remains high, if that is the case an error has occurredand three 'beeps' will be heard.
− The second test checks if the data line remains low, if that is the case an error has occurredand four 'beeps' will be heard.
− The third test checks if the address lline remains high, if that is the case an error has oc-curred and five 'beeps' will be heard.
− The fourth test checks if the address lline remains low, if that is the case an error has oc-curred and six 'beeps' will be heard.
8.2.2 Non-volatile RAM test
The integrity of the persistent data that's stored in RAM is tested during the Micro Series start-up procedure. If the integrity check fails, the persistent data will be cleared. When that part ofthe integrity test fails that checks if the retrieved data is correct, then a RAM hardware failure orversion conflict has occurred and a continuous beeping sound will be heard.
8.2.3 FLASH MEMORY test
During this test the contents of the program memories (flash memory) are tested. This is doneby adding the contents of all addresses according to a specified calculation and comparing theresult of this addition to a single byte checksum stored in the flash memory.
If an error is detected, two 'beeps' are generated.

8.2.4 Mechanical reset
The analyser performs a reset on the bellows pump and the filterwheel to establish the "zeropositions".
The following two situations can occur when the pump is being reset:
1. The vane position is not in the opto
First the inlet valve is closed and the outlet valve is opened.Next the bellows pump moves up until a transition is detected by the reset opto. Followingdetection the bellows pump moves down 1000 steps, followed by moving up again until atransition is detected. Then the pump moves up another 200 steps. This position is calledthe reset position and is the starting position for new aspirate actions.Finally the outlet valve is closed.
2. The vane position is in the opto
First the inlet valve is closed and the outlet valve is opened.Next the bellows pump moves down until a transition is detected by the reset opto. Follow-ing detection, the pump continues to move down another 1000 half steps. The bellowspump then moves up until the transition is detected by the reset opto. Thereafter the pumpmoves up 200 steps. This position is called the reset position and is the starting position fornew aspirate actions.Finally the outlet valve is closed.
If an error occurs during the reset procedure, the following message will be displayed:
009 Pump init. fails
8.2.5 Filterwheel reset
The filterwheel is brought to a defined position determined by the path of light through the flow-cell. After initialisation, the filterwheel is positioned so that reset position (dark position) blocksthe path of the light through the flowcell.
First the stepper motor of the filter wheel is enforced, so that the stepper motor will be fixed atit's reset position.Secondly, the filterwheel is rotated 2½ times, so that the reset position will be estimated with theaid of the optical switch when passing the notch at a constant speed.Finally the filterwheel is set to it's reset position, so that when the filterwheel isn't being used itblocks the path of the light through the flow cell. This is the position of the filterwheel when it isnot operating.
If an error occurs during the reset procedure the following message is displayed:
010 FW Init. fails

8.5.1.1 Checking the filters
Follow the procedure below to check the correct functioning of the filters via the absorbance,delta ABS and delta REF readings.
1. Press the Enter key or use the Left/Right cursor keys to focus the cursor on the edit box forthe Filterwheel Position on the right hand side.
2. Use the Up/Down cursor keys to choose a filter whose readings are to be checked thenpress the Enter key. The instrument will display the Absorbance, delta ABS. and the deltaREF. readings for the chosen filter.
The following positions are read only. The values displayed below are examples
Absorbance 3630
delta ABS. -17714
delta REF. 932
The example values shown here are calculated as follows: (the measured absorbance atthe current wavelength and gain) minus (the measured absorbance at 340 nm gain 0). Thelast measurement will be executed just once at the beginning of the absorbance measure-ment.
a. Absorbance: this value is the direct measured absorbance value in 0.1 mAbs.
b. delta ABS.: this value is the current measured absorbance corrected with theabsorbance at gain 0 in 0.1 mAbs.
c. delta REF.: this value is the difference between the measured reference signal and the theoretical reference signal in 0.1 mAbs.
Note
When the absorbance value is too low to measure, i.e., the gain is too high, in this case, insteadof the absorbance value, the value -99999 is shown.
3. Set the required Gain value from 1 to 10 using the number keys, in accordance with reagentor test procedure specifications.
4. Use the Space bar to turn the lamp off or on at the check box.
5. Press the CALIB softkey to ensure that the instrument can determine the exact centre ofeach filter installed. The following message is displayed, replacing the word SERVICE:"Calibrating... may take 2 mins".

It is possible to weigh a predetermined amount of water to check the correct functioning of thepump. Before carrying out this check, the instrument must first carry out a flush routine to en-sure that all system tubes are completely filled with water (Please refer to the User's Manual,chapter 10.2, "End of Day Maintenance"). Follow the procedure below to check the correctfunctioning of the pump:
1. Focus the cursor on the Volume edit box using the Left/Right cursor keys.
2. Enter the amount of water to be weighed.
The amount to be entered has a factor of ten (10). Thus if the amount of water to be dis-pensed is 1200 μl, then the figure entered must be 12000. The maximum figure that can beentered is 15000, which results in 1500 μl being aspirated.
3. Press the Enter key to aspirate the pre-set volume. It is now possible to check the volumeby means of:

9.1 Overview
The Micro Series is an error-tolerant system with proven accuracy and precision of results andgeneral handling. However, it is not possible to exclude all possible problems. This chapter of-fers you assistance in localising and solving possible problems as well as referring you to theappropriate chapters in both the Service and User's Manuals. It does not provide an overallstep-by-step troubleshooting guide, but is intended to supply general guidelines on how to pro-ceed in case of failure.
User maintenance is of the utmost importance. It is extremely important that the cleaning in-structions for the fluid system as described in the User's Manual are followed closely. As a gen-eral rule, flow systems are sensitive to the quality of the sample. Pollution of the sample cancause obstructions of the fluid system, for example, air bubbles, clotting, protein fibres etc.
Chapter 10, "Maintenance" of the User's Manual describes user maintenance procedures. TheError History function described in chapter 10.8 of the User's Manual will assist in localising andthus in solving problems.
Chapter 11, "Troubleshooting" of the User's Manual contains some symptoms, probable causesand remedies as well as corrective procedures that the user should carry out before requestingthe assistance of the service technician.
As an experienced service technician, you will appreciate that a considerable degree of prob-lems with instruments are in general the result of external causes. Environmental problemssuch as heavy line voltage fluctuations (peaks, spikes and so forth), inadequate earth groundconnections, dust (especially in combination with high ambient humidity), corrosive vapours(acid), dirt, amongst others, can all affect the performance of an instrument. Also the test pa-rameters should be checked against the manufacturer's package inserts when errors appear in-stead of results.
High intensity light (direct sunlight or from artificial sources) might also affect the operation ofsensitive photometric equipment. Additionally, the instruments will be adversely affected by ex-treme high or low ambient temperatures (see chapter 4, "Installation Procedures").

9.1.1 Electronic failures
If an electronic failure is suspected you should always check the supply voltage first, as this isprobably the most critical section of the electronics.
9.1.2 Processor board
The main processor board has been manufactured using SMD technology. This implies that on-the-spot repairs or even in the workshop will not be possible. Therefore, we strongly advise thatyou contact the service department of Vital Scientific. N.V. in case of failure.
9.1.3 Mechanical failures
Check the sipper tube and fluid system for leaks or obstructions as well for loose connectionswhen obvious mechanical problems occur, for example, sample/water under the instrument. Ifthe fluid system is blocked, it should be flushed with distilled water and 5% detergent (Mucasol)at 37 °C for at least 10 minutes. Inspect tubing at least once a year and replace if required.

9.2 Error Messages
The error messages that the instrument displays in the case of a malfunction are given in thetable below. The table is made up of five columns: the Error number column and the Error textcolumn relate to the error message. The Cause column lists possible reasons for the error be-ing issued. The User column contains the suggested user reaction. Finally, the Service columnlists suggested action to be taken by the service technician or, where appropriate, refershim/her to the chapter and manual where a more detailed procedure is described.
A basic assumption for the error messages listed in the table below is that the power supply isfunctioning correctly. Please refer to chapter 6.3.2, "Power supply, detailed specifications", andin the Appendix, A.4, "Electrical Drawings", Logic power supply (17 of 21) and 24V / -20VInverter & 12V supply (18 of 21).
The errors listed below are not always displayed on the monitor during operation of the instru-ment, but are always recorded in the error history. For example, the error 011 "ROM Failure" isnot always displayed on the monitor, because the instrument solves the problem autonomously.However, all errors and warnings are logged in the error history (please refer to chapter 10.8,"Error History" in the User's Manual for a more detailed explanation of this function).
The service technician should also refer to chapter 6, "Technical Information". The relevantdrawings and wiring diagrams are contained in the Appendix.
