2.1.1 INTRODUCTION

In the figure below you find an overview of the main functional units of the analyser.

Figure 2.1 – Overview of the analyser

The various instruments can have different sample rotors.

Refer to the special pages for the various machines for the right rotor.

A stepper motor drives the rotor.

There are 24 positions for 25 ml bottles and 8 positions for 7 ml bottles in the reagent rotor. Some openings for 25 ml bottles can be combined to fit 50 ml bottles.

Adapters for a placing a 7ml bottle on a 25 ml position are also available.

All positions can be assigned as Reagent 1 or 2 (start reagent)

The reagent disk compartment can be cooled by an external cooling unit.

A stepper motor drives the reagent rotor.

Some instruments have an optional special reagent rotor.

VITAL SCIENTIFIC 2.1

2. FUNCTIONAL DESIGN SERVICE MANUAL

2.1.4 SAMPLE ARM

The sample needle aspirates a programmed volume and will dispense it into a cuvette of the cuvette rotor. After pipetting, the sample needle mixes the reaction mixture. After sampling and mixing the needle will be washed inside and outside.

Because the sample arm has to move in two directions, two stepper motors; horizontal and vertical drive the sample arm. The sample arm is equipped with a level detector that will detect the liquid level of the sample cup and will generate an error message when not enough sample is present in the cup.

The reagent needle will aspirate a programmed reagent volume and will dispense it into a cuvette of the cuvette rotor. After pipetting (reagent 2) the reagent needle will mix the mixture in the cuvette. Then the needle will be washed inside and outside.

The reagent arm must be able to move in two directions and is therefore driven by two stepper motors. The reagent arm is equipped with a level detector to check if sufficient reagent is present. It is also equipped with a controlled heating element to preheat the cooled reagent.

2.1.6 ISE ARM

Optionally the instrument is equipped with an ISE-arm to connect the instrument to an optional external ISE (Ion Selective Electrode) measuring unit.

This external ISE unit is controlled by the instrument and the ISE arm aspirates sample from the cuvette rotor. The ISE arm is integrated in the mixer unit.

2.1.7 PIPETTORS

The two Hamilton syringes, a 1000

µ l and a 100

µ l type, are used in combination with two valves for reagent and sample pipetting.

The pipetting system is water filled with air bubble separation.

A stepper motor drives each syringe, and the detection of the syringe up and down positions is done by opto-switches.

2.2

VITAL SCIENTIFIC

SERVICE MANUAL 2. FUNCTIONAL DESIGN

The cuvette rotor contains 48 cuvettes, which are thermostatted at 37

°

C.

The path length of a cuvette is about 7mm, but absorbance values are re-calculated to 10 mm path length. A stepper motor drives the cuvette rotor.

The heating of the cuvette rotor is done by means of two controlled Peltier elements.

The cover of the cuvette rotor is equipped with a heating element to avoid condensation at the inside of this cover.

The washing unit washes the cuvettes after usage. At the first 4 positions of the washing unit a long needle aspirates the cuvette contents and a short needle fills the cuvette with water. At the fifth position the water is aspirated, at the sixth position a drying block dries the cuvette.

With the option concentrated waste installed the liquid aspirated at the first cleaning action (i.e. the reaction mixture) is lead to the concentrated waste deposit.

The washing unit is equipped with liquid sensors to detect flooding of the cuvette.

2.1.10 COOLING UNIT

Cooling of the reagents is done by means of an external cooling unit.

This unit keeps the cooling liquid in the container at a fixed temperature, which must be set at the cooling unit.

On its turn the cooling liquid is pumped through a heat exchanger in the analyser where cool air is fed through a closed reagent compartment.

VITAL SCIENTIFIC 2.3

2. FUNCTIONAL DESIGN SERVICE MANUAL

2.2 TIMING PRINCIPLE

The instrument always works with a fixed cycle time. In this fixed cycle all the necessary dispensing, mixing, washing and diluting take place and also a fixed number of measurements are made, regardless if they are necessary or not.

This fixed cycle assures that all the necessary measurements for a test always take place at the right moment. Even if no measurements have to be taken (for example during washing of the first cuvettes) the cycle takes place. In that case the reading of the photometer is ignored.

There are two operating modes, the Mono Mode, for single reagent use, and the

Dual Mode, where a second reagent can be used. The user can switch over from the

Mono Mode to the Dual Mode, but not during testing. After switching from one mode to the other the instrument will reset.

The Mono Mode has a cycle time of 20 seconds, so the theoretical throughput of the instrument is 180 tests/hour (3x60). In practice the throughput is a little less, due to possible sample blanks and the start-up time which is 13 minutes.

In the figure below you find a graphic representation of the 20-second cycle.

The line represents the cuvette that starts at the sample dispensing position.

Figure 2.2 Graphic representation Mono cycle

Note that after every cycle the cuvette rotor shifts one position.

The cycle time of the Dual Mode is 27 seconds, therefore the theoretical throughput of the instrument is 133 tests/hour.

In the figure below the sequence of the 27 seconds cycle is shown.

Figure 2.3 - The 27-second cycle

Because in the Dual Mode use can be made of a second (or starter) reagent in this cycle there is time for the second reagent to be dispensed and mixed.

Instead of dispensing a second reagent, these extra 7 seconds can also be used for predilution of a sample. In case of predilution, in one cycle the sample is added to the diluent, and in the next cycle (in the extra 7 seconds) the diluted sample is picked up by the sample needle and dispensed in the next cuvette, which already contains the appropriate reagent.

2.3 MECHANICAL DESIGN

SERVICE MANUAL

The reagent arm is responsible for the moving of the reagent needle to the correct position. The construction of the arm is such that the driving for the movements is decoupled; separate stepper motors drive the up/down movement and the sidewardrotating movement.

The reagent arm has in fact seven discrete horizontal positions in which the arm normally is positioned. A reset opto and a subsequent number of stepper motor steps determine these positions.

Horizontal: Cuvette position

Wash position

5 * Reagent Rotor position

There are three discrete vertical positions and one variable vertical position:

Vertical: Up (or reset) position

Cuvette position

Wash position

Reagent (variable value, depending on the liquid level in the

reagent bottle

For the discrete positions a value will be assigned with respect to the reset position, which will comply with the number of steps the stepper motor needs for the arm to reach its destination.

The variable position for the reagent level indicates the arm to lower itself just below the reagent level in the bottle (enough to aspirate 400

µ l).

This position is determined by a level detection and the subsequential lowering with a predefined number of steps.

VITAL SCIENTIFIC

SERVICE MANUAL 2. FUNCTIONAL DESIGN

2.3.2 SAMPLE ARM

The sample arm is responsible for moving the sample needle in the correct position.

The construction of the arm is such that the driving for the movements is decoupled; separate stepper motors drive the up/down movement and the sideward-rotating movement.

The sample arm has five discrete horizontal positions, which are represented by five stepper motor co-ordinates:

Horizontal: Cuvette position

Wash position

Sample rotor outer position

Sample rotor middle position

Sample rotor inner position

In the vertical direction there are three discrete and one variable position:

Vertical: Up or reset position

Cuvette position

Wash position

Sample position (variable position, depending on the sample volume)

The reagent rotor has 32 discrete positions that correspond with the 32 reagent bottle positions, although optional different reagent rotors are possible.

The sample rotor has 72 discrete positions that correspond with the 72 sample cup positions.

The measuring unit consists of the following items mounted together as one unit:

• rotor

•

filter

The measuring rotor is stepper motor driven and the reset position is detected by an opto-switch.

The measuring rotor has 48 discrete positions that correspond with the 48 cuvettes which must be positioned in the lightpath. Since a full turn of the stepper motor is

2400 steps, the distance between two cuvettes is 50 steps.

Two Peltier elements are mounted under the measuring rotor to heat the cuvettes.

The selection of the wavelength is done by means of an 8-position filter wheel.

The standard mounted filters are 340, 376, 405, 436, 505, 546, 578, and 620 nm.

The filter wheel has 8 discrete positions that are 48 steps away from each other.

The reset position is detected by an opto-switch.

The lamp unit consists of a lamp holder with a mechanism for adjusting the lamp.

2.3.5 WASH UNIT AND BELLOWS PUMP

The wash unit is built up with a stepper motor that is driving via a timing belt the wash arm.

Figure 2.4 - Wash unit

The positions of the wash arm are detected by three opto-switches.

The opto-switches are mounted on a PCB (the so-called wash arm board).

The wash unit normally has three vertical positions. During normal operation two of them are accessed; up and down. Opto 1 is for detecting the up position and opto 2 is for the down position. Opto 0 is for detecting the high position of the wash arm (for changing of the cuvette rotor).

2.10

VITAL SCIENTIFIC

SERVICE MANUAL 2. FUNCTIONAL DESIGN

During the reset also the presence of the cuvette rotor is detected.

The wash arm will go downwards until it touches the bottom of the cuvette.

At this position opto 1 the vane is still positioned in opto 1. When no cuvette is present, the vane is not in opto 1, and error NO CUVETTE will be displayed.

The bellows pump consists of six separate bellows mounted together in one unit.

A stepper motor drives the bellows. The bellows pump has two defined positions; a zero position and a predefined full stroke volume position (500

µ l is equal to 833 steps). The detection of both positions is done by opto-switches.

2.3.6 PIPETTOR

The pipettor is a precise diluter with motor driven valves and syringes.

The pipettor is controlled by one of the Motion Control Boards.

The liquid displacement is controlled by two stepper motor driven syringes: the sample syringe (100

µ l) and the reagent syringe (1000

µ l).

Each syringe is connected to a special connection block that contains the valve unit.

The valves are driven by small DC-motors via a worm-wheel construction.

The syringe drive assembly is shown in figure 2.5.

The top and bottom position of the plunger is detected by two opto-switches.

Figure 2.5 – Syringe drive assembly

The lower opto is also used for home initialisation, during the reset.

The four opto’s are mounted together on a separate PCB.

The syringes are made of glass and the plungers are teflon-tipped.

The tubes that are connected to the valves are also made of teflon.

The communication with the external ISE measuring unit is done by a serial RS232 inter face. The serial interface connector is mounted at the left side of the instrument.

Figure 2.6 - ISE arm

An electro magnet that moves the needle into its aspirate position drives the ISE needle. An opto switch detects the lower position of the needle. The electronic driver circuits for magnet and mixer are located on the ISE driver board. The system board does the control of these functions.

2. FUNCTIONAL DESIGN SERVICE MANUAL

Some of the stepper motors are equipped with an encoder disc on the shaft.

In conjunction with two opto-switches (A and B) they check the number of steps and the direction of the stepper motor. This way loss of steps can be detected.

VITAL SCIENTIFIC

Figure 2.8 - Sample level detection

2.15

2. FUNCTIONAL DESIGN SERVICE MANUAL

The principle of this detection is based on capacity.

An oscillator signal of 10V / 13 kHz is connected to the metal sample rotor, which is isolated from the rest of the frame. The sample cup and sample itself serve as dielectric so the signal can reach the sample needle.

When the sample needle touches the sample this is immediately detected by the

PLL-circuit (Phase Locked Loop), after which the sample needle will go down a few more steps in order to be able to aspirate enough sample.

When the sample cup is empty, no capacity is detected.

Message INSUFFICIENT SAMPLE FOR XXX will appear in the results.

Note that the dead volume depends on the type of the sample rotor.

The principle of the reagent level detection is exactly the same as that of the sample level detection.

Note that when no reagent is detected, the error message NO REAGENT ON XXX is immediately displayed on the screen.

2.16

VITAL SCIENTIFIC

SERVICE MANUAL 2. FUNCTIONAL DESIGN

The water cask is provided with a system to detect the water level and to switch the water pump on and off. Two float switches (based on reed relays) which are mounted in the water cask (see figure 2.9) detect the level.

Figure 2.9 - Water level detection

The system board controls the water pump. When the upper float switch detects “no water” the water pump will be switched on for 25 seconds. When after this time the float switch is still detecting “no water” the error message WATER RUNNING OUT will be displayed on the screen and the pump will be switched on again for 25 seconds.

When the lower float switch detects “no water” the error INSUFFICIENT WATER will be displayed. When this message appears the instrument will not dispense sample or reagent any more, however it will finish all the measurements in the cuvette rotor.

VITAL SCIENTIFIC 2.17

2. FUNCTIONAL DESIGN SERVICE MANUAL

2.4.4 OVERFLOW DETECTION FOR CUVETTE

The cuvette rotor is equipped with an overflow detection to detect if the liquid level in a cuvette becomes too high.

The principle of the detection is based on conductivity. The principle is shown in figure 2.10. The resistance between the liquid sensor and the needles is measured as soon as the wash arm is going down; If the liquid sensor touches the water in the low position of the wash arm the resistance is low and the system will report a

WATER OVERFLOW MEASUREMENT DISC error.

2.5 OPTICAL SYSTEM

Figure 2.11 shows the optical system of the analyser.

2. FUNCTIONAL DESIGN

Figure 2.11 - Optical system

The light source consists of a long-life quartz iodine lamp (12V/20W, 2000 hour life-time), and the detector is made of a UV-enhanced silicon photocell.

Monochromatic light is achieved by using single IFL (InterFerence Line) filters.

The filters are mounted in a stepper motor driven, 8-position filter wheel.

Depending on the programmed wavelength, the microprocessor will automatically select the correct filter, and the filter wheel will move to the correct position.

The used IFL filters have an integrated coloured glass filter, depending on the wavelength of the IFL filter two types are used. For the low wavelength range a filter is used to reduce the effects from stray-light, by blocking light of higher wavelength.

For the high wavelength range a filter is used to level difference in energy at the high ends of the spectral range.

This will be necessary, because the spectral emission of the quartz iodine and spectral response of the detector are much higher in the visible and near infra-red range than in the near ultra-violet range.

The filament of the lamp is projected in the lens in front of the filterwheel.

After the filterwheel a beam splitter is mounted which splits the light beam;

90% of the signal is going through the second lens and cuvette, and 10% of the signal is going into the direction of the reference detector.

The function of the reference detector is to detect and to compensate for the fluctuations of the lamp.

The optimal alignment and lamp intensity can be reached by adjusting the lamp.

2.6 FLUID AND VACUUM SYSTEM

Figure 2.12 shows an overview of the main parts of the fluid and vacuum system.

Figure 2.12 - Fluid and vacuum system

Optional the instrument is equipped with two separated waste circuits for diluted and concentrated waste. The concentrated waste consists of the waste of the first needle from the wash arm (the reaction mixture) and the waste from the optional ISE unit.

The normal diluted waste is coming from the rest of the system like the other needles from the wash arm and the wash positions for reagent and sample needle.

The waste for both systems is collected into two separate waste containers.

2.20

VITAL SCIENTIFIC

SERVICE MANUAL 2. FUNCTIONAL DESIGN

2.6.1 FILLING OF THE CUVETTE ROTOR AND WASH POSITIONS

The filling of the cuvette rotor is done by means of a bellows pump that is driven by a stepper motor. The volume is 4 x 500

µ l per rotation cycle. In total 4 cuvettes are washed (filled and emptied) at the same time. Also the sample needle is washed with 500

µ l water at the wash position.

When the water pump is switched on, water will be pumped from the water bottle to the water cask. The water cask is equipped with a system for detecting the water level (see section 2.4.3). When the water level is too low, the water pump will be switched on, and when the level is high enough the pump will be switched off.

When the switch-off circuit is defective, the water will flow back into the water container via the overflow connection.

The filling of the cuvette rotor and sample wash position is performed as follows:

Valve V6 to V10 are not activated, the bellows goes downwards and is aspirating water. Then V6 to V10 are activated and the bellows goes upwards and is dispensing water in the cuvette rotor and sample wash position and the valves V6 to

V10 are de-activated again.

The reagent syringe fills the reagent wash position. The reagent valve will move to the aspirate position and the syringe plunger will go downwards and the syringe will be filled with water. Then the valve will move to the dispense position and the plunger will go upwards and water will be dispensed into the reagent wash position.

2.6.2 EMPTYING THE CUVETTE ROTOR

In the ‘active’ state the vacuum pump is always running. When all valves are closed/de-activated this will cause a vacuum in the collecting cask. In order to empty the cuvettes valve V2 will open and the wash arm needle will aspirate the cuvette contents into the collecting cask.

Optionally a separate parallel concentrated waste circuit will aspirate the contents of the first cuvette into a concentrated waste collecting cask.

Valve V2 is closed and valve V4 and V5 are activated. When V2 will be opened the waste of the reagent wash position will be sucked into the collecting cask. When V5 is de-activated the waste of the sample wash position is sucked into the collecting cask, and the collecting cask will be emptied.

2.6.4 EMPTYING THE COLLECTING CASK

Valve V2 is closed and valve V3 is opened

Pressure will be put on the collecting cask by activating V1 and V12, and the collecting cask will be emptied and collected into the waste container.

Valve V1, V3 and V12 are de-activated again.

2.7 REAGENT COOLING

Reagent is cooled by means of an external cooling unit.

A cooling liquid is cooled down to a temperature set at the cooling unit.

This cooling liquid is then pumped through a heat exchanger in the analyser, from where cooled air is pumped through the reagent compartment.

The cooling liquid is based on Glycol. The temperature of the cooling unit is set at the cooling unit itself and is not checked by the analyser. Note that the temperature of the reagent is always higher than the set temperature.

The temperature setting of the cooling unit is protected so the user can not change the temperature. Below the procedure for changing this temperature is described.

SERVICE MANUAL 2. FUNCTIONAL DESIGN

When changing this temperature the situation in the lab should be taken into consideration.

The System Board is also connected to the Photometer Board, where the actual photometric measurement is done. The measured values are transmitted to the

System Board and the external computer.

3.2 SYSTEM BOARD

The overall functional control of the instrument is done by the System board and is exercised by a Z80 microprocessor.

The program for this board is stored in an EPROM.

The system board receives requests for tests from the external computer.

By means of serial communication ports it sends commands to the Motion Control

Boards for all the movements and by means of digital outputs it drives, via driver boards, the valves and the pumps. Besides it switches on and off via digital outputs the various heating elements.

In combination with the photometer board the system board measures the extinction.

The intermediate results are stored in the system data memory (RAM) that consists of a 32 Kbytes CMOS RAM.

The serial interface between the system board and the motion control boards is controlled via the three Serial Input Output (Z80-SIO) devices.

The Killer Input Output (Z80-KIO) is an integrated device which contains a CTC

(Counter Timer Control), a PIO (Parallel Input Output) and a SIO with the following functions:

KIO-CTC: A/D conversion of the photometer signal and timing control.

KIO-PIO: controls the valves V1 to V14 and the signals for the vacuum switch, waste switch, pumps etcetera

KIO-SIO: serial connections with external computer and optional ISE-interface

The schematics and the wiring diagram of the system board is shown in section 8 of this manual.

The two stepper motors and their control circuits are identical.

The first two blocks are the microprocessor and the PIO that are part of the I/O array.

In principle there are only four lines necessary to control the stepper motor device

(L297). This device has 8 output lines that control the stepper motor drivers (L6203).

On the output lines of the drivers fast ramping rectifiers can be found, to protect the drivers against high induction peaks.

There are also LED’s to indicate if the output of the driver is activated.

When the stepper motors are normally running it seems that all LED’s are on because the switching time is much faster than the human eye can detect.

3.4 TEMPERATURE CONTROL BOARD

The temperature control board has the following functions:

•

temperature control of the cuvette rotor

•

temperature control of the reagent needle

•

lamp voltage control

•

temperature driver for cuvette cover

•

temperature driver for plate heat exchanger

The temperature control of the cuvette rotor is always working, unless the instrument is in the halted state or if a cuvette temperature error occurs.

The reagent needle is only heated when the instrument is in the active state.

On the service menu the needle temperature can be checked.

3.4.1 TEMPERATURE CONTROL CUVETTE ROTOR

The cuvette rotor is heated by two Peltier elements and the temperature is measured by a linear thermistor network. This network consists of two precision resistors, which are mounted on the board. The thermistor is mounted inside the cuvette rotor assembly.

The thermistor is connected to a 1V precision voltage supply and is wired to produce a voltage output that increases linearly with the temperature. The temperature control circuit can be divided into a number of separate circuits with the following functions:

•

input amplifier

•

3.5 INPUT AMPLIFIER

The input amplifier circuit is built around IC10 which is a voltage OP-AMP (OP07).

The purpose of this amplifier is to amplify the output of the thermistor (5.76 mV/

°

C) to an adequate level. The amplification is approximately 70x, therefore the output voltage of IC10 is approx. 400 mV/

°

C. To extend the dynamic range of the amplifier, the inverting input of IC12 is derived from a reference voltage of 408.8mV.

3.5.1.1 DIFFERENTIAL AMPLIFIER

The second stage of the temperature control consists of a differential amplifier (IC9) and a compensation circuit board, which is mounted at the front of the analyser.

The compensation board consist of an adjustable current source that is used as a remote sense temperature application.

IC4 will amplify the difference between the inputs.

3.5.1.2 DUAL FOLLOWERS

The output signal from the differential amplifier is connected to the inputs of the dual followers (IC8a and b).

Depending whether heating or cooling is required, the output of the differential amplifier is positive or negative.

The two dual driver outputs are connected together via diodes and connected to the switched power supply.

This signal that is connected to the power supply varies between 0V and -15V.

When the input signal is 0V the output voltage of the power supply is also 0V.

Depending which output of the followers is positive one half of the bridge driver is active. This means that the two outputs are controlling the current direction through the Peltier elements, and therefore selecting heating or cooling.

3.5.1.3 PELTIER DRIVING CIRCUIT

The Peltier elements driver circuit is built around the four FET transistors (T2, T3, T4 and T5). The two Peltiers are connected in series between point 3 and 4 of PL2.

If the measured temperature is lower then 37

°

C, the output voltage of IC9d is positive. The output voltage of IC8a will also be positive and will drive T3.

T7 will take away the gate voltage of T2. The current through the Peltier elements is going via T5, the Peltier elements and T2 to ground.

If the measured temperature is higher then 37

°

C, the output voltage of IC5b will be positive, and will drive T4. The current through the Peltier elements is then going via

T3, the Peltier elements and T4 to ground.

The System board can monitor the temperature within ± 0.1

°

C by means of the

READY-signal (RDY). If the temperature is not reached within 5 minutes the microprocessor will switch-off the Peltier elements and will generate the CUVETTE

TEMPERATURE ERROR.

Note that if the cuvette temperature error is acknowledged the error will not reappear any more until the instrument is reset. The heating circuit is switched off!

3.5.2.1 INPUT AMPLIFIER

The input amplifier circuit is built around IC7 which is a voltage OP-AMP (OP07).

The purpose of this amplifier is to amplify the difference at the inputs to an adequate level. The amplification is approximately 70x. The non-inverting input is derived from the NTC output (0.408 V at 37

°

C). To extend the dynamic range of the amplifier, the inverting input of IC7 is derived from a reference voltage of 408.8 mV.

3.5.2.2 DIFFERENTIAL AMPLIFIER

The second stage of the temperature control consists of differential amplifier IC6c.

The output of IC7 that corresponds to the actual temperature is present at the inverting input of IC6c, while the other input is connected to the reference voltage.

This reference voltage can be adjusted and is derived from the 10 volts reference source. IC6c will amplify the difference between the inputs.

3.5.2.3 DRIVING CIRCUIT

The output signal from IC10a is going via a amplification circuit (IC6d) to the switched power supply circuit.

The System board can monitor if the temperature is within ± 0.1

°

C by means of the

READY-signal (RDY). If the temperature is not reached within 2.5 minutes the microprocessor will switch-off the heating element and will generate the REAGENT

NEEDLE TEMPERATURE ERROR.

The lamp stabilizer circuit is built around IC5, a voltage regulator. One of the lamp leads is always connected to the voltage (14 V). The other lead is connected to ground via FET transistor T1. When the power is applied, the gate of the FET is controlled via resistor R34 and diode D10. The lamp voltage is measured via a resistor network and compared against the reference voltage. The regulator controls the gate of the FET transistor in such a way that the measured lamp voltage is the same as the reference voltage. The lamp voltage can be adjusted with P1.

The lamp can be switched on and off by activating or deactivating opto-coupler

OC3B. The lamp will be activated by the microprocessor on the System board.

The overcurrent through the FET transistor T1 is protected by means of transistor T6 and R6.

3.6 PHOTOMETER BOARD

On the Photometer Board is the photometer electrical circuit. In the figure below the block diagram of this board shown.

Figure 3.8 - Block diagram Photometer Board

The complete electrical diagram is given in section 8 of this manual.

The photometer circuit can be divided into the following two circuits:

•

programmable input amplifier

•

lin/log

On the photometer board are two identical circuits present; one for the actual measurement (PHOTOM), and one for the reference measurement (LAMP-REF).

The function of the reference measurement is to compensate variations of the lamp.

Because these circuits are identical only the operation of the actual input amplifier is explained.

The principle of the input amplifier is illustrated in figure 3.9.

The figure shows the actual amplifier (IC11) with one of the photo-diodes as input source and four switches controlled by the microprocessor (of the system board).

By means of these four switches, sixteen different possibilities for the gain settings can be programmed.

3.12

VITAL SCIENTIFIC

SERVICE MANUAL 3. SYSTEM ORGANIZATION

Figure 3.9 - Input amplifier principle diagram

Referring to the electrical diagram of the photometer board of section 8, the gain setting is performed by four signals, which are derived from the PIO of the System

Board (P-G0 to P-G3). These signals directly control the FET switches of IC9.

Three of these FET switches perform, in combination with the relay contact from

REL2, the actual amplification setting. By switching resistors R19, 20, 21, 22, 23 and

24 into the circuit, whilst the remaining resistor R26 is switched by means of the relay contact. The relay is switched by means of a FET switch IC8c and is controlled by the fourth signal (P-G3). The same fourth signal that controls the relay controls also FET switch IC9c and has a compensation function. This FET switch will switch resistor R18 into the circuit from amplification step 8 and onwards.

Note that the functions are reverse, from amplification step 0 to 7, P-G3 is active high, this means that REL2 is activated and FET switch IC14c also, and will short the resistor R24.

The gain factor (per step) equals the power of 1.5 and can be programmed in 16 steps from 1.5 to the power 0 up to 1.5 to the power 15, which will result in an amplification of 1 and 438 respectively.

Changing the amplification by 1 step, will cause an absorbance change of approximately 255 mAbs (log 1.5 x 10/6.88 = 0.255 Abs). According the law of

Lambert Beer the absorbance is proportional with the lightpath. The log 1.5 value has to be recalculated because the amplification steps are based on a “standard” lightpath of 10mm. Therefore the absolute range is 15 x 0.255 = 3.82 Abs.

During the ‘Blank’ procedure a series of actions is started to produce the optimal gain for the programmable input amplifier. Because the gain of this amplifier is controlled in steps only, It needs no argument that it will be virtually impossible to control the amplifier to produce a certain voltage, corresponding to 100% transmission (0 Abs.) exactly.

Therefore, utilising a method of ‘successive approximation’, commonly used in

A/D-converters, the gain is set in such a way that it drives the output of the amplifier to fit within a specific window. This window determines the maximum and minimum

(negative) absorbance limits of the instrument. The lower limit is fixed at 145 mAbs, and the upper limit of the blanking window is 436 mAbs.

The theoretical range of the photometer is 0.436 + 3.82 = 4.256 Abs, but at this maximum amplification the noise and drift effects are also high.

Therefore a maximum amplification step of 12 is chosen.

At amplification step 12 the maximum absorbance value is 3.06 Abs.

The lowest level that still can be measured is therefore 3.496 Abs. (3.06 + 0.436).

The table below illustrates how the FET switches must be set to produce the required gain.

Note that if during the blank procedure, the instrument is not able to produce a gain, resulting that the absorbance value is within the ‘blank’ range an error will be displayed.

Right after blanking, the output voltage of the input amplifier will be between 5V and

7.94 V, unless overrange or under-range has occurred.

3.6.2 Lin / log converter

3. SYSTEM ORGANIZATION

Figure 3.10 - Lin/Log converter

Conversion is achieved by utilizing the logarithmic discharge curve of capacitor C4.

The voltage over this capacitor is compared to the linear voltage (Vx) and the time from the beginning of the discharge until both voltages are equal, correspond to the logarithm of the measured signal.

The discharge time is measured by starting a counter at the moment that the actual discharge is activated. The counter will be stopped the moment both voltages are equal (measuring and capacitor voltage).

The lin/log converter circuit consists of:

•

Precision voltage source which supplies a very accurate 10V (IC5).

•

Logarithmic generator (IC2 and C4)

•

Comparator

•

FET (IC8)

•

Digital parts that consist of a Counter Time Control (CTC), which is situated on the system board.

VITAL SCIENTIFIC 3.15

3. SYSTEM ORGANIZATION SERVICE MANUAL

At the start of the logarithmic conversion, capacitor C4 will be charged to 10 Volts derived from IC5, by means of closing the FET switch (IC8d).

After a certain time (1msec.), the counters in the CTC will be enabled.

At the same moment, the selection of the input signal for conversion takes place

(photocell signal or reference signal) and the FET switch IC8d is switched off, causing the logarithmic discharge curve to appear at the output of IC2.

This signal is compared to either a reference voltage via FET switch IC8a, or to the measuring voltage via FET switch IC8b.

The reference voltage for the comparison measurement is also obtained from the 10

Volts precision reference source, and has a nominal value of 100 mV.

During the time the logarithmic decreasing signal is higher than the measuring- or the reference-voltage. Depending which one has been selected for conversion , the counters in the CTC are fed with the high frequency clock (1.8432 Mhz), derived from the main clock signal (KIO).

When the logarithmic decreasing signal is higher than the measuring signal as described above, the output of comparator IC13 is high. This signal is referred as

‘start stop signal’ (PH-STRT) and the time this signal is high is depending of the voltage of the measured signal. This signal together with the high frequency clock are connected to an AND port. The output of this AND port (IC6b) is connected to the CLK/Trigger input of the 16-bits counter of the CTC.

When the logarithmic signal becomes less than the measuring / reference signal, the output of comparator IC4 is dropped low and the high frequency clock will not pass the AND port anymore.

In case the measuring signal (which is in fact the relative transmission in this stage of the signal processing) is selected, the amount of clock pulses stored in the counters after conversion corresponds to the logarithm of this signal.

To compensate for temperature and component variations, measuring and reference signals are measured alternately.

As already mentioned before, the reference value is equal to 100 mVolts, which in turn corresponds to 20.000 counts (and 2.000 mAbs.) after conversion. When due to changes in the characteristics of the circuit the reference value is no longer equal to

20.000 counts, it needs no argument that the measuring value will be affected proportionally! Therefore, measuring values are compensated for variations in the log conversion circuit by means of the measured reference signal.

It will be obvious that this kind of compensation has its limits.

Therefore, a range of plus and minus 1000 counts has been established, and as long as the reference value is within the specified window of 19.000 to 21.000 counts, the circuit is assumed to function correctly and compensation will be carried out as described before.

When a reference value is measured which is outside the specified range, the instrument will give an error.

The liquid detection circuits of the sample needle and the reagent needle are located on the PLL board and are built around IC1 and IC2 for the sample level detection and IC3 and IC4 for the reagent level detection. The detailed diagrams are shown in section 8 of this manual.

An oscillator signal of 13 kHz (10V top-top) is made by the oscillator circuit built around opamp IC2 (IC4). This signal is connected to the mechanical assembly of the rotor.

This oscillator signal will be returned to this circuitry via the cup (bottle), needle, the

The coupling between the metal rotor and the metal needle is capacitive, where the tube and the liquid act as di-electricum.

The sensitivity of the liquid detection can be adjusted by means of one of the two potentiometers mounted on top of the PLL board.

This memory should be as large as possible. You can check the total free memory with the "mem" command in a DOS-box. It should be as close to 600k as possible.

To get as much memory for the DOS application as possible, check if the extended memory drivers are installed. The config.sys file should contain the next three lines:

device=c:\windows\himem.sys

device=c:\windows\emm386.exe ram

dos=high,umb

Depending on the Windows version, the second line should be omitted.

Try this and check if this gives more memory.

Always reboot your PC when you have changed the config.sys file!

For further information check your DOS manual.

4.7.1 TWO ABSORBANCE TEST BOX

The Two Absorbance test box is a test box that contains a simple circuit consisting of a number of precision resistors, a capacitor and a push-button switch.

By means of this box the photometer board can be calibrated (see section 6.3).

Figure 7.1 - Test box circuit

The operation of the circuit is as follows:

A negative voltage (-15V) is connected to the test-box presenting the input signal to the input amplifier of the photometer board. When the push-button is pressed 1/100 of the original voltage is presented to the input amplifier via the resistors.

This will result in an absorbance of 2.000 mAbs on the display.

The Two Absorbance test box can be ordered from Vital Scientific under code number 6001-283.

There is a special tool available to easily perform mechanical adjustment of the sample and reagent arm (see section 5.8 and 5.9).

The tool consists of a metal block (of 97mm) which supports the reagent or sample arm during these adjustments.

Please note that it is not strictly necessary to have this tool but it will make the adjustment easier.

The tool can be ordered from Vital Scientific under code number 4999-001.

4.8 PRINTED CIRCUIT BOARD REPAIR

The detailed information supplied by this manual provides the opportunity for trouble shooting at component level, however at an economical and quality point of view you can decide to exchange the complete PCB.

The electronic design of the printed circuit boards (A1 to A9) is such that most electronic parts used are commonly available in every well-equipped workshop.

However, do not use any components with lower specifications then the original items, because this can affect the performance of the instrument.

A list of components is included with every circuit diagram at section 8 of this manual.

The electronic boards of the computer assembly are designed in such a way that repair is virtually impossible. The reason is the small and compact design, the use of SMD components and the price of the boards. Therefore the components used on these boards cannot be ordered from Vital Scientific, only the complete PCB’s are available.

NOTE: More and more components are very sensitive for static electricity.

Please take the necessary precautions to avoid damage of the PC-boards.

5. MECHANICAL ADJUSTMENTS SERVICE MANUAL

The lamp must be adjusted in such a way that the two bars LAMP REF and CUVET reach a maximum.

These values must be at least as high as the displayed minimum.

The two left bars represent the intensity of light measured by the reference detector

(LAMP) and the measurement detector (CUVET).

Procedure:

•

Note: Normally both the CUVET and REF signals reach their maximum at the same lamp position. If this is not the case, adjust for maximum REF signal and execute the adjustment described below.

5.2

VITAL SCIENTIFIC

SERVICE MANUAL 5. MECHANICAL ADJUSTMENTS

Sometimes it is possible to gain some lamp energy by readjusting the cuvette photo sensor. Normally this is only the case when the inner rotor assembly has been removed.

This adjustment is as follows:

1. Loosen screws D at top of rotor.

2. Turn the inner rotor assembly slowly clockwise or counter-clockwise and fix housing on position with the highest reading on CUVET.

3. Re-adjust lamp position for maximum signal on CUVET.

Figure 5.2 - Photo sensor adjustment

Note: So far, when adjusting the lamp and/or sensor position for maximum signal at

340 nm, it does not matter whether there is a cuvette rotor placed or not, or if this cuvette rotor is empty or filled with water.

For the next check a water filled cuvette rotor has to be placed.

The condition of the filters can be checked by pressing F1 (Check Cuv. Abs.) and the absorbance is measured for each wavelength (340 to 620 nm). The absorbance values are graphically displayed on the right side of the screen.

The absorbance must be at least as high as the minimum level.

The actual absorbance and counter values are not displayed in this menu but are shown in a special menu called OPTICAL ELECTRONICS.

5.3 CUVETTE ROTOR ADJUSTMENT

In principle this adjustment has been done at the factory of Vital Scientific.

Only when the measurement rotor has been disassembled it is necessary to check the lightpath and in some cases to re-adjust it. It has no sense to re-adjust unless both adjustments of paragraph 5.2 have been executed first.

Checking the lightspot:

•

Remove the cuvette rotor.

•

Select in the service menu, “measurement disc/filter” and reset the cuvette rotor [F1] and filter wheel [F2].

•

Put some transparent tape (Scotch) on the detector side of the cuvette rotor.

•

Select 546nm [F6] and switch on the lamp [F8].

There will be a green lightspot visible on the tape.

The lightspot must be in the middle of the hole behind the tape, if not perform the cuvette rotor adjustment.

13.3) Check if opto 1 is “0”, if not, bend opto 1 carefully downwards in such a way that it just switches to “0”.

14) Remove cuvette.

15) Reset wash arm [F1].

Check if “no cuvettes” is “1”.

If not, check if opto 1 is in right position and reset the wash arm again.

5.5 BELLOWS PUMP ADJUSTMENT

The bellows pump consists of 6 bellows (one not used) which aspirate or dispense simultaneously. One bellow (on the motor side) controls the wash water of the sample needle. Four bellows control the wash water in the 4 cuvette wash positions.

The optimum cycle volume for the pump is 400

µ l and can be adjusted by means of shifting beam A towards respectively away from the bellows.

To decrease the volume: loosen screw 1 and 2 move beam A away from bellows tighten screw 1 and 2

To increase the volume: loosen screw 1 and 2 move beam A towards bellows tighten screw 1 and 2

The screws are accessible through a slit in the baseplate.

COMPLETE ARM ADJUSTMENT

This adjustment is only necessary when a repair on this part of the arms has been carried out. If only a small horizontal adjustment is necessary, for example because the needle has bent a little bit, then carry out the small horizontal arm adjustment.

The height of the arms is determined by ring G (see figure 5.6), the horizontal position is determined by the clamp assembly B. However, in order to readjust the height the clamp assembly also has to be loosened. This means that after performing the vertical adjustment the horizontal adjustment must be performed too.

Initial Check

1) Reset the sample arm [F1].

2) Check if the free space between upper side of clamp assembly B and bottom side of swing unit A is ±0.5 mm.

If not, shift the reset opto a little up or downwards (by means of the two fixing screws). Reset the sample arm and check again if the free space is sufficient.

3) Check if the distance between the top of the mechanical assembly and the bottom of the arm (without plastic cover) is 97 mm.

If not, the vertical adjustment must be carried out.

5.9 VACUUM SENSOR ADJUSTMENT

When the instrument is in the ‘active’ state the vacuum pump is always running.

However, the vacuum level varies continuously due to opening and closing valves while the vacuum cask works as a buffer.

The vacuum sensor will become “0” when the vacuum level becomes too low.

The actual indication of the sensor can be checked in the service menu VACUUM

Select in the service menu, vacuum system.

Connect the vacuum meter between tube connector 2 at the rear of the instrument (green, vacuum) and the tube going to the vacuum sensor.

Select in the service menu OFF for all valves [F1 to F8], and switch on the vacuum pump. The vacuum level must be

≥

-0.7 bar. After switching off the vacuum level it may not reduce more then 0.1 Bar in 90 seconds.

When this is the case there is a leakage in the vacuum pump or in the tubing.

Switch on the vacuum pump again and cover the rinsing place of the sample needle with your finger.

While keeping your finger on the rinsing place switch on valve 2 and valve 4.

Let the vacuum escape little by little by means of lifting your finger a little bit and check that the vacuum sensor switches from VACUUM to NO VACUUM at a level of about -0.3 bar.

If not: adjust the switch level of the vacuum sensor by turning the setscrew, accessible from the rear of the instrument (remove back cover).

Turning clockwise = increasing switch level.

Select in the service menu, ELECTRONICS, page 3.

In this menu the complete description for the adjustment is given.

Temperature adjustment of cuvette rotor:

First check if the cuvette detection is correct in the service menu.

The status of the analyser should be “INACTIVE”, because when the status is

“HALTED” the Peltiers of the cuvette rotor are not activated.

The screen must show: CUVETTE TEMPERATURE: OK.

This adjustment must be done in the main menu.

You have to run a wash and fill cycle. During the run all the covers must be mounted and the cuvette cover must placed.

After the wash and fill cycle the following adjustment can be done:

•

Measure the temperature in the cuvette rotor with a very small temperature probe. When the probe has too much mass it will cool down the cuvette and a good indication of the temperature is not possible anymore.

•

Place the temperature probe in the cuvette that is in the lightpath.

•

Adjust the temperature to 37.5

°

C (± 0.2) by means of P3 (which is mounted behind the front plate). Turning P3 360

°

clockwise means, as an indication, an increase of temperature of 0.4

°

C.

After an adjustment of the temperature repeat the wash and fill cycle and check the new set temperature!

6.5 ADJUSTMENT OF THE PLL (LIQUID SENSE)

This procedure describes the adjustment of the PLL circuit for liquid detection.

The potentiometers for this adjustment can be found just behind the tube connectors for the sample and the reagent arm, if you remove the top cover (next to the printer).

The procedure is the same for both arms. Most important is to prevent that the PLL circuit is too sensitive and thinks it aspirates liquid while in fact it does not.

By means of surrounding the needle by full cups / bottles the capacitive coupling between needle and rotor is made very high. The tube and the liquid act as dielectricum Even then the needle may not sense liquid erroneously.

Note that the information in this section does not provide an overall step-by-step trouble shooting guide, but merely is intended to supply the general guide lines on how to proceed in cases of a failure and in addition some symptoms, probable causes and remedies are provided.

Being an experienced service engineer you will appreciate that considerable part of problems with instruments in general result from external causes.

Environment problems like heavy line voltage fluctuations (peaks etc.), inadequate earth ground connections, dust especially in combination with high ambient humidity, corrosive vapours (acid), dirt etc. can all affect the performance of an instrument.

For sensitive photometric equipment, high intensity light (direct sunlight or from artificial sources) might affect the operation as well. In addition extreme high or low ambient temperatures will adversely effect these instruments.

As for everything, prevention is far better than repair; therefore we strongly advise to follow the preventive maintenance instructions closely.

Finally, the customer maintenance will be of utmost importance as well. It is very important that the cleaning instructions for the fluid system as described in the

Instruction Manual are followed closely.

Inconsistent measuring results can be defined as follows: drop-outs and too low measuring results.

Symptom: Occasional drop-outs in the measurement values; too high or too low.

Probable cause: Remaining water in the cuvette rotor, because the wash arm is

Solution: not emptying sufficiently.

Check the adjustment of the wash arm (the distance between the needle unit in the down position and the cuvette bottom must be

0.5mm) if this is according the procedure given in section 5.3.

Check the functioning of valve V2 and V4.

VITAL SCIENTIFIC

SERVICE MANUAL 7. ERROR HANDLING

Symptom: The values of the controls are too low.

Probable cause: The temperature of the cuvette rotor is too low.

Solution: Check the temperature of the cuvette rotor by following the adjustment procedure of section 6.5.

Blank error:

Symptom: The SD value of the cuvette blank is higher then 0.0150.

Probable cause: The rotor is damaged or polluted.

Solution: Replace the rotor by a new one and perform a new blank procedure.

Probable cause: When the reagent needle is dispensing water which contains air

Solution: bubbles the cuvette rotor, caused by leakage of the liquid system or leakage, the teflon syringe tips or syringe valve.

Check the tubing on leakage.

Check the condition of the teflon tips and valve and replace if necessary.

7.2.3.1 The instrument does not start-up

Check the fuses in the mains cable connection

Open slot A2 and check the power supply voltages with respect to tab6: tab 2: 5.1 V tab 8: 14 V tab 1: 30 V

The 12 V has no connection to this board, but the fans run on 12V.

7.2.3.2 Communication check system board <> motion control boards

If a reset fails (see paragraph 3.11 for the power-on sequence) the instrument will stop the reset procedure and will generate an error for the part that fails but probably also for parts that have not been reset yet.

If the reset fails one can check if this is caused by a failing communication between the system board and the motion control boards in the following way:

•

•

select

RELEASE

The system board now communicates with the motion control boards that send back the version of the EPROM they contain. If this communication fails (retry a few times!) you might try to replace the KIO that usually is responsible for this failure.

If the communication suddenly fails during normal operation the instrument generates error Exxx COMMUNICATION ERROR.

VITAL SCIENTIFIC 7.25

7. ERROR HANDLING SERVICE MANUAL

As all motion control boards are the same you can exchange two boards in order to know if a problem is caused by the board or by something else.

The EPROMs determine the function of the board and they must stay with the slot!

Note that if you exchange board A6 (measurement rotor) that you copy the position of the hexacode switch from this board to the new board on this position.

Replacing the KIO of the MCB sometimes helps if it turns out that a sensor signal is present on the board but not recognised by the system.

7.2.3.4 Bad cuvette blank results

If the results of the cuvette blank are bad (low C.V. values):

•

Check the lamp adjustment, if you can not get it right:

•

Exchange the lamp

•

Check lamp voltage (12 V)

•

Check sensor voltages (>100 mV)

•

Exchange board

•

Exchange the cuvette rotor

•

If the results are bad only for one filter exchange this filter.

•

If the results are bad for certain cuvettes at all wavelengths:

•

Take out the cuvette rotor and put it back 90 degrees turned.

After running a new cuvette blank you can see if the bad cuvettes shifted 12 places or not. If not:

•

Check lightpath and lenses on dirt and hairs

•

Check that the light beam goes through the centre of the cuvettes, with adhesive transparent tape sticked to the cuvette, wavelength 546 nm.

If not change the setting of the hexacode switch on MCB A6.

VITAL SCIENTIFIC

SERVICE MANUAL 7. ERROR HANDLING

LAMP REF; indicates the intensity of light on the reference sensor.

CUVET indicates the intensity of light on the normal sensor.

CUVET (Abs) indicates the absorbance of the cuvette for the various filters.

The relative length of the bars that indicate the absorbances should be as in the figure, i.e. first bar longest, then every bar shorter.

If a bar is much longer or shorter than expected, this indicates a bad filter.

The 340 nm (1) and the 546 nm (6) filters are usually the first to deteriorate.

After adjustment of the lamp no infinite signs (

∞

) may appear on top of the bars

LAMPREF and CUVET.

7.2.4.1 Water or vacuum system

If there are problems in the water or vacuum system (water overflow, no vacuum):

•

select the appropriate menu and check both pumps and all the valves (you can hear them switch).

If pumps or valves do not operate:

•

Connect a spare valve or exchange two connectors to see whether the component or the electronics is defective

•

Change valve board (check fuse first!)

•

Change board

•

Check the complete water and vacuum system systematically with the help of the service menus and the Vacuum diagram (see figure 2.12)

VITAL SCIENTIFIC 7.27

7.2.4.2 Liquid detection problems

If there are problems with the liquid detection first make sure that the shaft and the bearing of the needle are completely dry. Also note that the minimum sample volume is 300 microliter for normal samples, 200 microliter for controls and standards and 100 microliter for paediatrics.

Check the PLL adjustment if necessary (see paragraph 6.5).

If this is not enough:

•

If the instrument gives the INFO INSUFFICIENT SAMPLE, although there is clearly enough sample turn the corresponding potentiometer 360 degrees more clockwise (more sensitive)

•

If the instrument thinks it picked up sample that was not there turn the potentiometer 360 degrees counterclockwise (less sensitive)
