2.1 Servicing Schedule (yearly procedure recommended) 2.1.1 Maintenance Routine without Dismantling the Centrifuge 2.1.1.1 Electrical Installation and Safety

• switch OFF the centrifuge and disconnect the unit from power, check voltage supply and mains fusing (20 Amps, slow blow characteristic)

• check condition of plug and wall socket - (let) replace defective parts • check cord condition and fixing / connection - replace or refit it • check condition of instrument socket and replace it in case of bad contacts

2.1.1.2 Location and Mechanical Installation

• check the base (ground, table, lorry with lockable wheels etc.) for resonance-free and stable conditions

• check for a well ventilated place and sufficient distances to walls or adjacent equipment, without exposition to direct sunlight

• check the levelling of the centrifuge drive with use of a spirit level 2.1.1.3 Lid Tumbler Mechanism and Safety Device

• connect the centrifuge to power and switch ON • check for correct automatic lid closing and self-acting lid opening - if in disorder, readjust lid,

swivel hinges, and/or locking devices • check the rubber gasket for lid’s and bolt’s sealing and replace, if damaged • for checking the electronically safety circuit: start the centrifuge, let it shortly run and stop it, the lid

must not be unlocked by the microprocessor as long as the speed is more than 60 rpm - if safety circuit is out of function, replace main board

2.1.1.4 Cleanliness of Spin Chamber and Motor Casing

• open the lid and remove the rotor (for loosening turn the T-handle Allen key (5mm) in arrow direction - see rim of rotor chamber)

• clean the spin chamber with a dry and absorbent cloth (remove all dust and moisture - see also section for Cleaning)

• Check the cleanliness of the motor flange and take care of the annular slot around the motor shaft: penetrating fluids can damage the upper motor bearing or electronics, remove fluids with an injector and/or absorbent paper

2.1.1.5 Rotor and Accessories Condition and Sealing

Servicing Schedule (cont.) 2.1.1.6 Rotor Fixing and Motor Cone

• check the perfect condition of the collet chuck and replace it in case of malfunction (thread is worn out, horizontal grooves etc.)

• check the condition of the motor cone: the centrifuge must not be used any longer, if the cone is • the thread should be greased a little

2.1.1.7 Temperature Level • check the gauze (behind the air inlet slots) underneath the front panel for free ventilation,

insufficient air flow will lead to an inadmissible temperature rise of compressor, motor and electronic parts

2.1.1.8 Imbalance Behaviour

• install available and empty rotors and check the imbalance behaviour with rotor dependant cut off and run through weights (see 2.4) and replace worn out motor rubber mounts, motor or faulty main board

2.1.2 Maintenance Routine after Dismantling the Centrifuge Casing 2.1.2.1 Motor Supporting Elements

• check the supporting and damping elements of the drive motor and replace them in case of increased rubber abrasion or abundance of imbalance but at least every 3 years

2.1.2.2 Braking Circuit

• check the function of the braking circuit (warming up of brake resistor, even and noiseless brake effect) and replace defective parts in case of malfunction

2.1.2.3 Lead and Screwing Connections

• check the terminal and plug connections of all leads and on all boards and electrical components, tighten all loosen screwing connections, refit or replace defective parts

• check the screwing connections of all boards, mechanical and electrical components and re-tighten them if necessary (use screw locking lacquer for motor mounts and lid lock assembly)

2.1.2.4 Protection Earth Core and Grounding Connections

• check the protection earth core for continuity and all grounding plug connectors (see also 2.6 Electrical Safety Check)

• check isolation resistance and accessible current (see 2.6)

• Insert the admissible imbalance weights in the same manner, the centrifuge must run through 4 times to maximum rotor speed.

2.6 Cleaning of Instrument Parts ATTENTION - WARNING! The electrical and electronic components must not be cleaned with moist detergents! For Cleaning the centrifuge housing or its accessories see Operating Instructions section 1 (maintenance and care). • Electronic components

Clean dusty components carefully with a dry and soft brush and remove loose dust with a vacuum cleaner.

• Fans Scratch off carefully with a knife or similar tool the crusted dirt from the fans’ blades. Resulting grooves or marks must be removed subsequently with a fine abrasive cloth. Loose dirt is to remove with an absorbent cloth or vacuum cleaner.

• Vent holes Remove dirt from the vent grid behind the front panel by using a brush and vacuum cleaner.

• Condensers of cooling plant The louvers between the condensers’ heat air deflectors have to be vacuum cleaned. In case of persistent dirt the unit must be carried to an appropriate place where the condensers can be cleaned with compressed air from inside to outside. Bent heat air deflectors have to be realigned correctly.

3.2.1 Power PackThe power pack consists of 2 transformers, 2 bridge rectifiers and 3 voltage regulators, itgenerates the following low voltage levels:• U1 = 5V: by switched-mode regulator LM2575T-5.0

supplies all processors and its electronic components on main and indicationboard

• U2 = 12V: by fix voltage regulator 7812supplies sensor circuits on the rotor indication plus the speed and imbalancedetection board

• U3 = 24V: unregulatedis used for the driving of both lid lock motors and relays K2, K3;the reference potential of U1,U2,U3 is A1: connected to protective conductor(GND)

• U2 = 15V: by 2. transformer, rectifier and fix voltage regulator 7815serves for supply of driving of the power electronics via the protection circuit byclosed lid switchesreference potential: A2 (UD-) CAUTION - MAINS POTENTIAL!

3.2.2 Intermediate CircuitThe DC intermediate circuit serves as an energy store between the AC power input and thetransmitted motor performance. The DC intermediate circuit consists of several reservoir capacitorswhich are softly charged across the power correction module (PFC) when ever the unit is switched on.When switching the unit off, the DC voltage of the intermediate circuit is discharged across a path ofresistor and voltage monitoring LED H3.

3.2.3 Frequency ConverterThe motor is 3-phased, provided with chopped direct voltage blocks (chopped frequencyapprox. 20kHz, amplitude is height of DC intermediate voltage). These blocks are variable infrequency and pulse-width modulation, 120° out of phase. These 3 phases are controlled duringacceleration, running at set speed and deceleration (e.g. for small speed: low frequency andsmall pulse-width length will be affected). The FC is protected against over current, overtemperature and over-voltage which will be indicated by LED H2.

The control program (ROM) is integrated in the controller component.The most important operating parameters (e.g. the maximum data for all rotors, the last operatorsettings, the basic values for speed and temperature controlling, data of acceleration and decelerationcurves as well as 9 data sets of program places plus pre-temperation program) are stored in the nonvolatile (NV)-RAMs. The actual value of all centrifugation cycles (“CYL“) is also shown in the display(as fifth No.) when ever the unit is powered on, before the check routine for all program places puts anend to the initialisation time (approx. 18s). The CPU co-operates with the ASIC 80 component via the8 bit data bus and some control lines. The ASIC 80 is a specially designed integrated circuit for thedriving of Heraeus centrifuges (with induction motor), containing a pulse counting stage for speedmeasuring and some protecting functions for the power electronics. An other micro-controller (XXX)and NV-RAM (XXYY) are serving the tasks for automatic imbalance and lid release control. When theCPU (590) has identified the installed rotor type, the imbalance controller gets this code to read in arotor and speed dependent imbalance limitation curve from a third NV-RAM (4434). The analogueimbalance signal is filtered, converted into digital form and continuously comperated with this specificlimitation curve. If the actual imbalance signal will rise at any speed beyond the limit, the error signalfor imbalance load “bAL“ is switched over to the CPU. An additional task of the imbalance controller isthe surveillance of the lid’s unlocked condition: Both lid motors can only be supplied with 24V by relayK2 if the speed is less than 60 rpm.

3.2.5 Temperature MeasuringThe temperature inside of the rotor chamber is measured by a PT100 sensor. The sensor’shead is inserted into a guide boring of the motor rubber flange. The signal is led across the plugconnection (XU) to the main board where a voltage to frequency converter converts the PT100resistance changes into a variable frequency. This frequency is processed by the ASIC80 andfinally red in by the CPU over the data bus. The calibration of the F/U converter in the range of0°C to 50°C is regularly controlled by 2 resistors of 0.1% tolerance.

3.3 Power Factor Correction (PFC – Module)An increasing number of loads in the public power supply networks do not – as in the past –take the required current from the mains power supply in form of sinus waves but in form ofshort and high current pulses. Mostly, these are electronically regulated loads (e.g. switchedmode power supply units, electronic engine controls, dimming devices), which increasingly gaincurrency due to their low power loss ratios and the numerous advantages resulting therefromThe input current of switched mode power supplies and other electronic loads has the shape ofa pulse wave Here, the problem is as follows: With the majority of loads, the current pulsesoccur approximately at the same time, i.e. nearby the peak voltage value. For a short period oftime, the mains must cope with a current input which is larger than the loads actually require,whereas in the remaining time it is loaded to a much less extent. The consequence is: Due tothe current spikes and the impedance typical of the power mains, the voltage curve alsodeviates from the sinus-wave form, which may cause problems with sensitive loads. Moreover,all components of the sup-ply network must – strictly speaking quite unnecessarily – beoverdimensioned, if this imbalance proliferates. In order to prevent this from happening, thepublic mains power supply network operators initiated the EN61000-3-2, based on thepreceding standard EN60555-2.In the Multifuge 4 it is used an active Power Factor correction. Here, the input capacitor isdecoupled from the mains for example by means of a so-called set-up converter, so that theinput current can now be controlled electronically. The power supply unit constantly determineshow much energy is needed on the secondary side and draws an (almost) sinusoidal current tothe necessary extent fromA red LED shows that there is power at the components and it you shouldn’t be touched until itis “off”.

3.4 Speed Detection BoardOn a small board, which is attached underneath the motor, the circuits for speed detection and signalshaping are arranged.The motor speed is optically detected by an infra-red light barrier. The motor axle has a slot at thesame level as the light barrier. This effects that the light beam will be interrupted twice during onemotor revolution.A following pulse shaping stage on board forms square-topped pulses which are led via XW2 to themain board where they are passed on to imbalance controller (see 3.5.3) and further to ASIC80component.The speed pulses are counted by an integrated circuit stage of the ASIC80 component to givethe CPU a hand with fast calculation of the exact motor speed.

3.5 Imbalance Detection (on speed detection board)On the speed detection board a piezoelectric acceleration detector is additional fixed. Dependent ofthe rotor imbalance this sensor generates an analogous voltage signal which is led via a followingband-pass filter to plug connection XW1/2 to main board, where it is analysed by CPU. When theCPU) has identified the installed rotor type, the speed dependent imbalance limitation curve from E-PROM The analogue imbalance signal is filtered, converted into digital form and continuouslycomperated with this specific limitation curve. If the actual imbalance signal will rise at any speedbeyond the limit, the error signal for imbalance load “bAL“ will be displayed and the unit slows down.

3.6 Rotor IndicationIn the rotor’s bottom 4 magnets are forced, being alternately arranged in polarity and positioned toeach other to different distances on a constant circular ring (segment steps of 20°).A Hall sensor is exactly fixed below to the sensor board. The magnets are switching a flip-flopstage by which different pulse lengths and pulse intermissions are generated during one rotorrotation. By this signal the CPU is able to detect up to 65 different rotors and the correctdirection of rotation, too.

3.7 Key and Indication BoardThe key and indication board is mounted behind the operating panel. The connection to the mainboard is done by a screened 6 polar cable by which the serial data transfer as well as the low voltagesupply of 5V is verified. The 7-segment displays, the control LED’s and the operating keys aremanaged by an own controller unit (first identification No. 526) in multiplex processing.For the programming serves EASYCONTROL II (see Operating Instructions).

3.7 Cooling plantThe Multifuge 4 KR/Cryofuge 5500i/Sorvall RC4 is equipped with a high-grade cooling plant, to meetit’s requirements of driving power and compact design. The CFC free refrigerants R134A evaporate atlow temperatures (≤ -20°C) and absorbs through this the frictional heat from chamber produced by thefast spinning rotor. 2 fans serve for even air flow through condenser so that the refrigerant’scondensing temperature is kept on a low levelA specially designed heat exchanger serves for essential undercooling of the condensed refrigerant toensure an optimum evaporation and a perfect operation of the expansion valve. To maintain lowevaporation and resultant condensation temperatures on one hand and to support the startingprocedure of the compressor on other hand, a thermostatic expansion valve with 1.0bara MOP isused.The minimum achievable sample temperatures are depending on speed, rotor type and a littleon ambient temperature. After a compensating time, given by the pre-cooling or pre-heatingprogram as optimal result, the rotor has reached the selected set temperature within a toleranceof ± 2K.To reduce the power consumption during acceleration phase the compressor will not beswitched on. After reaching the set temperature and low temperature selection the compressorwill be activated. But during acceleration both fans will work.

After run is completed the fans will go on running 15 seconds to blow out the heat.

At standstill-cooling only the left fan will be activated

5.5 Replacement of Parts of the Cooling PlantFirst of all is to figure out that high ambient temperatures (ϑU >35°C), insufficient heat transfer(e.g. polluted condenser, de-heater, air gaps) or electrical errors (like defective fans, sensor ormain board, starting relay or capacitor) can be excluded from the cooling problem (see functiondiagram of cooling plant 4-10: pressure / temperature ranges are valid for continuous cooling atmax. speed, ϑU=25°C)!Procedure for replacing defective components of the cooling cycle:

• Dismantle the casing -see 5.1.and mount pierce valves onto the service lines• When gauging too little static pressure perform a leakage test (N2 max. 25bars)• Discharge the refrigerant with suction device into recycling bottle• In case of compressor (130) fault, let the oil run out into a bowl to recycle it• Unsolder defective component(s) and replace the dryer/collector assy (135), too• Let a little amount of dry nitrogen gas stream through the tubes when soldering to avoid scaling

on the tube’s inner surface• Do the evacuation and refill the system with the exact amount of liquid refrigerant on the pressure

side via a new external dryer (check amount with a balance or filling cylinder, re-solder theservice lines tight after finishing work)

• Reassemble the device and perform a cooling power test run

Revised - 27/07/20011. General

Successfully completing the Preventive Maintenance Checklist and Calibration CertificationProcedure as outlined will ensure that the instrument is properly maintained and calibrated toKendro specifications.

2. Equipment Required

• Digital Multimeter• Temperature Meter w/probe• Stopwatch• Photo Tachometer• Safety Tester• Multifuge/Cryofuge 5500i/Sorvall RC4 Service Manual• Centrifuge Operating Manual

Note: Check calibration due date on all test equipment before starting certification.

3. Documentation Required

• Preventive Maintenance Procedure and Checklist (Service Manual)• Calibration Certification Procedure and Form• Certification Label• Certificate of calibration for each piece of test equipment used to perform the certification• Training Certificate

Preventive Maintenance Check

• Perform Preventive Maintenance checks as outlined in the Kendro Service Manual to ensurethe instrument is in good working order without performing any calibrations.

• Complete the Preventive Maintenance Checklist. (calibration data will be filled in afterCertification)

Calibration Certification

• SPEED

Install a rotor, set the speed control to 3000 rpm and start the centrifuge. When the speed hasstabilized, measure the actual speed with an external tach(photo tach on multimeter where speed= frequency[no conversion]). Record measured speed and displayed speed in the speed section ofthe certification form. Set the speed control to max. rpm and after stabilization, record measuredspeed and displayed speed in the speed section of the certification form. Determine if the speedsrecorded meet the specifications on the form. If the specifications are met, proceed to the nextsection. A recalibration of the instrument is not possible.

Calibration Certification ProcedureMultifuge4 KR/Cryofuge5500i/Sorvall RC4

multi4cpr.doc 2 of 2

• TEMPERATURE

Place water into the rotor or bucket. Select a temperature of +4°C, maximum allowed speed ofthe rotor and time of minimum 3 hours. After that record the displayed temperature, measuredtemperature inside rotor or bucket after rotor has come to rest, in the temperature section of thecertification form. Repeat the test at 15°C. Record the values in the temperature section of thecertification form. Determine if the temperature values recorded meet the specifications on theform. If the specifications are met, proceed to the next section. A recalibration of the instrumentis not possible. Initial the temperature section. To pre-cool the rotor select pre-cooling programof the centrifuge.

• TIME

Using a stopwatch, check the timer by setting a 10 minute run. Start the centrifuge and measurefrom the time the start button is pushed until the timer switches to stop. Record the measuredtime in the time section of the form. Determine if the time value recorded meets the specificationsin the form. If the specifications are met, proceed to the next section. A recalibration of theinstrument is not possible. Initial the time section.

• SAFETY TEST

Using safety tester and connect the centrifuge to it. Measure Insulation resistance.. Select to EarthConductor resistance and touch with probe all mechanical part of the centrifuge. Resistance mustbe <0.2 ohms at all points otherwise check for good grounding. Measure accessible current toprocedure in the service manual.

Documentation

After filling in the certification information complete the following documentation:

• Log test equipment data on calibration certification form.• Review P.M.checklist and calibration certification form to ensure that all data and required

information has been recorded properly.(including your signature and date)• Fill out a certification label and place it on the right side of the centrifuge where visible or at a

location selected by the customer.• Ask the customer to sign the calibration certification form and place a copy in the customer’s

Certification Record Book for that centrifuge.• Place copies of the P.M.checklist and Field Service Report in the same Record Book.• Provide copies of your training certificate and test equipment calibration certificates if requested by the customer.
