Introduction Repairs must only be carried out by personnel authorised to do so by the manufacturer. Interventions and modifications at centrifuges, which have been conducted by persons not authorized by the HETTICH company, are at their own risk and entail the loss off all guarantee and liability claims. In such an event any guarantee claim or liability claim against the HETTICH company expire.

•

Only original spare parts and original accessories licensed by the Hettich company are allowed to be utilised. If no original spare parts or no original accessories are used, any guarantee claim or liability claim against the HETTICH company ceases to exist.

• • 2

Information about the operation of the centrifuge please see operating instructions. We reserve all rights for these technical documents. Meaning of the symbols Symbol on the machine: Attention, general hazard area. Before using the centrifuge implicitly read the operating instructions and pay attention to the safety relevant references! Symbol in the repair instructions: Attention, general hazard area. This symbol refers to safety relevant warnings and indicates possibly dangerous situations. The non-adherence to these warnings can lead to material damage and injury to personal. Warning! Danger for human lives by electric shock. This symbol refers to important circumstances.

Description of the centrifuge

The HAEMATOKRIT 210 is a microprocessor-controlled centrifuge which is comprised of the following electrical components: • Control panel • Power board • Motor • Brake resistor with overtemperature fuse • Lid lock system • Imbalance switch

All electronic components are on mains, due to the DC-coupling

Netz / Mains Verschluß / Lid lock Deckelschalter Lid switch Unwuchtschalter Imbalance switch

3.1

Control panel A3

The control panel have only restricted control tasks, it disposes of the following characteristics: • Input panel for operation parameters • Indication elements • Transmission of the signals to the power board via the interface. • Storing of centrifuge version • Storing the machine version and the brake setting. By means of the machine version the power board is informed which kind of centrifuge has to be controlled. Then the power board takes the corresponding values from the ROM. e.g. Max. Speed Acceleration and deceleration ramps • Communication with the power board via TTL interface. The power supply for the control panel is transmitted via the flat ribbon cable: Pin 1 GND Pin 4 +5V 3.2

Power board A1

The power board is an combination of: • Control panel • Voltage supply • Frequency converter The power board carries out the following tasks: • Power supply 15 V, DC for imbalance switch • Power supply 5 V, DC for control panel • Generating the motor power supply. (three-phase current with variable frequency and voltage) Functional description: The mains supply is rectified, smoothened and chopped into a pulse width pattern in three bridge elements with a microprocessor. • Slot for motor with integrated overtemperature switch • Monitoring the motor current • Evaluating the overtemperature switch in the motor • Slot for imbalance switch • Evaluating the imbalance switch • Slot for brake resistor • Triggering the brake resistor • Slot for lid lock • Triggering the lid lock magnet at standstill of the rotor • Evaluating the message line lid lock open/closed • Communication with the control panel via TTL interface • Error evaluation

7/34

3.3 • • • •

Motor M1 The motor is a three- phase asynchronous motor with two pairs of poles. The motor is protected against overheating by an overtemperature switch. The power board evaluates the overtemperature switch. The motor is controlled by the power board with a three-phase current with variable frequency and voltage.

3.4 • •

Brake resistor R1 and Overtemperature fuse F3 The braking copper which is integrated on the power board transfers the electrical energy produced during braking, from a voltage of 380 V with the 230 V version and 203 V with the 120 V version, to the brake resistor in a controlled manner. An overtemperature fuse protects the brake resistor against overheating. When the overtemperature fuse (F3) blows, the power board will be separated from the power supply.

3.5 •

•

Lid lock Y1 Opening of the lid lock is prevented by a latch. The lid lock can only be opened when the relay REL 602 on the power board is energised. This occurs when the rotor is at standstill and mains power is applied. The solenoid is energized and releases the latch. The centrifuge can only be started when the lid is closed. A microswitch on the lid lock detects the position of the lid lock (open/closed) and report it to the power board.

3.6

Imbalance switch S 2

• A switch detects any imbalance. • Imbalance can only be detected in running mode (starting, centrifuging and braking). • If any imbalance is detected, the drive is changed over to braking.

Imbalance switch-off

The imbalance switch-off is adjusted by the distance of the imbalance switch to the motor. With the centrifuge HAEMATOKRIT 210 the imbalance switch must rest against the motor. Adjusting the imbalance switch: • Switch off the mains switch and disconnect the centrifuge from the mains supply. • Remove the rotor. • Remove the centrifuge chamber, see chapter "Removing the centrifuge chamber". • Loosen both screws at the angle bracket of the imbalance switch on the outer part of the housing floor until you can shift it. • Shift the angle bracket so far until the imbalance switch will rest against the motor. • Tighten both screws at the angle bracket of the imbalance switch again.

Functional check after a repair

After a repair a functional check of the unit must be carried out. For functional check a test run with the loaded rotor must be performed. During the test run the followings must be checked: • • • •

Function of the keys, the display and the LEDs. Run-up and slow-down time, max. speed of the rotor. Values see operating instructions chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories". Operation of the imbalance switch. Current consumption. Values see repair instructions chapter "Technical specification".

After the test run a safety test must be carried out. Check the following values: • Insulation resistance • Protective conductor resistance • Leakage current

>2 MΩ < 0.2 Ω < 3.5 mA * * limit according to EN 61010

A laboratory centrifuge do not belong to those medical appliances which may be tested according to the regulation IEC 601 or corresponding national medical electronic standards. Laboratory centrifuges are classified as laboratory equipment. The regulations applying to laboratory equipment are IEC 1010 or European standard EN 61010.

Mounting and removing components

All components can be mounted and removed through the centrifuge chamber. For that purpose the centrifuge chamber must be taken out, see chapter "Removing the centrifuge chamber". When replacing the power board, make sure that there is sufficient heat conduction paste between the power board and the housing. If necessary, scrape off the heat conduction paste from the old power board and apply it on the new power board. The power board is fixed on the support sheet with 2 screws (Fig. 1, a).

Removing the centrifuge chamber Open the lid. Switch off the mains switch and disconnect the centrifuge from the mains supply. Remove the rotor. Undo both screws on the motor cover and remove the motor cover. Take out the centrifuge chamber and unplug the protective conductor from the centrifuge chamber. Removing the control panel Unscrew the hook at the lid and remove it. Undo the fastening screws of the lid moulding and remove the lid moulding. Undo both fastening screws of the control panel at the inner side of the lid. Take the control panel out of the lid from above.

25/34

10 Short the mains choke coil (L1) In countries, in which the European standard EN 61000-3-2 applies it is not allowed to short the mains choke coil. The mains choke coil reduces the mains input current below the limit values stated in the above mentioned European standard. If the centrifuge is run with undervoltage, that is mains frequency 50 Hz with a voltage < 205 V or mains frequency 60 Hz with a voltage < 210 V the voltage drop of the mains choke coil can cause the error " − 8 − Undervoltage". The short of the mains choke coil will increase the supply voltage of the frequency converter. • Pull both plugs (Fig. 2, a) from the mains choke coil. • Cut off both plugs and connect the ends of both cables together with a luster terminal (Fig. 3, a).
