2 Service 2.1 Servicing Schedule (Yearly Procedure) 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 (15/16 Amps slow blow characteristic) • check condition of plug and wall socket - replace defective parts • check cord condition and fixing - replace or refit it
2.1.1.2 Location and Mechanical Installation
• check the base (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 • check the levelling of the centrifuge - use a spirit level
2.1.1.3 Lid Locking Mechanism and Safety Device
• connect the centrifuge to power and switch ON • check for easy lid closing and self-acting lid opening - if in disorder, readjust lid looped
hook and/or hinges and smear hook slightly with grease • 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 Cover
• open the lid and remove the rotor (for loosening turn 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 Bucket Condition and Sealing
• check the condition of rotor and buckets (especially all supporting or stressed partitions • as jib arms, rim of bearing surface etc.): the rotor and/or buckets must not be used any
longer, if there are visible traces of mechanical damage or rust • check the condition of rotor and/or bucket sealing and replace in case of malfunction
2.1.1.6 Rotor Fixing and Motor Shaft
• 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 shaft: the centrifuge must not be used any longer, if the motor shaft is damaged
• the thread should be greased a little
2.1.1.7 Temperature dependence • maximum ambient temperature 40°C • check air guide for correct position, check space round the centrifuge. If airflow is
blocked – safety devises will cut off the unit • please notice that this is a non-cooled unit and sample temperatures of 20 K above
ambient could be possible

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 and replace worn out motor rubber mounts, the motor if required or adjust the imbalance switch
2.1.2 Maintenance Routine after Dismantling the Centrifuge Casing (see Section 5) 2.1.2.1 Motor Supporting Elements
• check the supporting and damping motor elements and replace them at least every 3 years. We recommend a yearly change. A maintenance kit is available
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 Ventilation and Proper Air Flow
• check the function of all fans (parallel cut in and out) and the air flow direction • check the air inlet slots in the casing and at the rear panel for free ventilation, insufficient
air flow will lead to an inadmissible temperature rise of motor and electronic parts 2.1.2.4 Lead and Screwing Connections
• check the terminal and plug connections of leads on all boards and electrical components and replace defective parts
• check the screwing connections of boards, mechanical and electrical components and re-tighten them if necessary
2.1.2.5 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 insulation resistance and leakage current (see 2.6)

Edition: 02 3 - 1 accuSpin 1 20.11.03 He/Ha
3 Functional Description 3.1 Block Functions The accuSpin 1 is a non refrigerated, microprocessor controlled low speed laboratory centrifuge with maintenance-free induction drive motor. The unit is constructed as bench top model with an extensive range of accessories. The centrifuge is build on a low vibration solid polymer bottom plate, the housing is made of sheet steel and surrounds the bottom plate completely. The front panel is made of a resistant plastic material where a easy cleanable overlay is self-glued. Housing and front panel are fixed tightly together to the bottom plate. The rotors are started directly with a frequency controlled main maintenance-free induction drive with high acceleration power. The drive is mounted with shock absorbers to the bottom plate and sealed with a rubber flange to the rotor chamber. Following boards and components are located inside the unit (see block diagram page 4-1):
• Mains switch
• Main board with central processor and 2 fuses for board protection, one fuse for the compressor (not used)
• Indication board with key and display processor
• Three phase induction drive motor with an integrated thermal over-temperature switch
(cut-out at 140°C). • Speed detection board is mounted underneath the drive motor
• Imbalance switch (not adjustable)
• Lid lock assembly with solenoid and 2 integrated micro switches
• Brake resistor mounted on bottom plate
• Fan for cooling the electronic components
Description
Edition: 02 3 - 2 accuSpin 1 20.11.03 He/Ha
3.2 Main Board Functions The main board is mounted on a metal plate behind the front panel. The components on main board are arranged in following groups (see wiring diagram page 4-2 and 4-3)
• Board fusing (2x 15/16 Amps. slow blown)
• Mains voltage supply for compressor control relay K1 , fuse 15/16A slow blown
• Noise Filter for suppression of radio interference, caused by the fast switching power electronics (10 kHz), in accordance EN 55011B
• Power pack for 3 different low voltage levels and integrated protection circuit
• Triac driving circuits for lid solenoid (release magnet) and fan
• Mains rectifier for DC intermediate circuit supplying brake control path and frequency
converter
• Micro controller (central processor unit) with circuits of imbalance, speed detection and temperature control
3.2.1 Power Pack The power pack consists of a transformer with 2 different secondary coils, each connected to bridge rectifiers and voltage regulators for the following low voltage levels:
1) U1 = 5V: supplies central processor, key and indication board and circuit for temperature measuring
reference potential A1: protective conductor (GND)
2) U2 = 12V: supplies the circuits of speed measuring and imbalance detection reference potential A2
3) U3 = 15V: stabilized - for the protection circuit: lid open, motor overtemperature and for control electronics of frequency converter reference potential A3! mains potential! EXERCISE CAUTION when measuring etc 3.2.2 Intermediate Circuit with Brake Chopper and Frequency Converter The DC intermediate circuit serves as an energy store between the AC power input and the transmitted motor performance. The intermediate circuit consists of a mains rectifier and two connected reservoir capacitors which are softly charged, continuously supplied during operation and slowly discharged after power off.
• Brake Chopper Electrical power is feed back into the intermediate circuit during motor deceleration (motor acts as generator). This braking power is transformed into heat by brake resistor R1 (terminal XD) so that the intermediate circuit voltage does not rise to an excessive level (level remains approximately constant see test points on main board). The brake resistor R1 is switched into the intermediate circuit by a fast switching (chopping) transistor. This transistor is controlled by the CPU via optical coupler stage.
Description
Edition: 02 3 - 3 accuSpin 1 20.11.03 He/Ha
Main Board Functions (continued)
• Frequency Converter The motor is provided 3-phased with chopped direct voltage blocks. These blocks are variable in frequency and pulse width modulation and are dephased to 120° between the motor windings. Beginning with low frequency and small pulse width chopped blocks, both parameters will be increased up to the operators set speed. By this variation the acceleration power of the drive motor can be effected. For deceleration the frequency and pulse width parameters will be reduced. The frequency converter is protected against over current and over voltage.
3.2.3 Micro Controller (Central Processing Unit) The controller block includes the central processor unit (CPU) 87C51FB and the data storage (NV-RAM) 9366 with the software identification No. for:
• CPU: 0498 (second displayed No. in speed field) • RAM: 4599 (third displayed No. in speed field)
The second parts of these No.'s (displayed in the time field) will be upgraded if necessary. The ROM with control program is integrated in the CPU. The most important operating parameters (e.g. the maximum data or the last operator settings) are stored in the NV-RAM. 3.3 Speed Detection Board The speed detection takes place opto-electronically through a slot in the motor shaft. A light-emitting infra-red diode and a photo-transistor are mounted on the speed detection board and located on opposing sides of the motor shaft (see page 4-9). So 2 pulses per motor revolution are generated, by which the micro controller calculates the real rotor speed or rcf value. The speed detection board is connected to the main board via the 3-pin plug XW.

Edition: 02 3 - 4 accuSpin 1 20.11.03 He/Ha
3.4 Key and Indication Board The key and indication board is mounted behind the front panel. A special micro controller is located on this board controlling the 7-segment displays, the control key LED’s and the operating keys. The communication with the central processor on the main board takes place via serial data lines in both directions (plug XI).

5.7 Imbalance Switch (426)
The imbalance switch has the task to switch off the centrifuge by incorrect loading of the rotor before reaching the normal speed. The imbalance switch is a mercury switch version and reacts on the change of position of the internal pill at app. 700 to 900 rpm during acceleration. The amplitude of the oscillation depends on weight and position of imbalance, rotor mass and damping property of the drive. For this reason no single weight can be specified to adjust the imbalance switch. • This selected assembly allows an imbalance of 25g and cuts off 100g
5.7.1 Imbalance Switch Assembly (426)
• The imbalance switch assembly is placed nearby the main board on a bolt at the chassis. You can reach it after removing the front panel
• Remove the screw and take the imbalance switch off the clip • Unplug terminal XE from main board and remove the imbalance switch assembly. • Install new imbalance switch analogously in reverse order
5.7.2 Adjustment of Imbalance Switch
An adjustment of the imbalance switch like known from other instruments cannot be done.
Procedure: • If there is a need of correcting the values a limited change can be done • You have to change the position of the internal mercury ball to a more sensitive position • Loosen the screw of the clip and move the switch assembly to a position of about 2 o’clock. • See also 2.4 Imbalance Behaviour

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 Service Manual to ensure the instrument is in good working order without performing any calibrations.
• Complete the Preventive Maintenance Checklist. (calibration data will be filled in after Certification)
Calibration Certification
• SPEED
Install a rotor, set the speed control to 3000 rpm (or wanted) and start the centrifuge. When the speed has stabilized, 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 of the certification form. Set the speed control to max. rpm and after stabilization, record measured speed and displayed speed in the speed section of the certification form. Determine if the speeds recorded meet the specifications on the form. If the specifications are met, proceed to the next section. A recalibration of the instrument is not possible.

• TIME Using a stopwatch, check the timer by setting a 10 minute run. Start the centrifuge and measure from the time the start button is pushed until the timer switches to stop. Record the measured time in the time section of the form. Determine if the time value recorded meets the specifications in the form. If the specifications are met, proceed to the next section. A recalibration of the instrument is not possible. Initial the time section.
• SAFETY TEST
Using safety tester and connect the centrifuge to it. Measure Insulation resistance.. Select to Earth Conductor resistance and touch with probe all mechanical part of the centrifuge. Resistance must be <0.2 Ohms at all points otherwise check for good grounding. Measure accessible current to procedure 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.
