Mounting and adjustment of the torsion spring

2.4.1 Purpose The torsion spring offers the user a comfortable support when closing and opening the centrifuge lid. When the "open lid" key is pressed, the lid lock is released on both sides and the lid bursts open and remains in a 20° position. Up to an angle of 45° the lid remains stable in any chosen position, beyond 45° it automatically opens to full extent. 2.4.2 Mounting The torsion spring assembly contains the following parts: torsion spring • • 2 plain bearing bushes (for shaft guidance) • 2 bushing nipples (for leg catch) • 2 set screws (aid for fixing legs) • dowel pin (for hooking the torsion spring onto the shaft) tube of Loctite 221 (for fastening screws) • • tube of Molykote TP42 (for lubrication of the torsion spring) Preparation: The defective torsion spring has been removed as described in Section 5, the old plain bearing bushes and bushing nipples have been removed. 1. Press the new plain bearing bush from outside into the right-hand bore of the chassis. 2. Slip on both bushing nipples up up to the head of the hexagon bolt M6x12. Fix the screws again to the chassis and secure with Loctite 221. 3. Push the old dowel pin carefully from the shaft using a pin punch, then push the new dowel pin on using a plane surface (e.g. a wooden panel).

Mounting the shaft and torsion spring: 4. Grease the short end of the shaft evenly using about 5 g of Molykote Molykote TP42. Attention! Do not cover the plain bearing with grease! 5. Slip the torsion spring onto the short end of the shaft (short loop first). 6. Push the long end of the shaft through the left-hand bore of the chassis and slip into right-hand plain bearing bush. 7. Press the plain bearing bush via the shaft into the left-hand bore of the chassis. 2.4.3 Adjustment Preassembly and alignment of the legs: 8. Push both legs onto the ends of the shaft such that the bores are horizontally oriented and the leg ends point forward. 9. Screw the M8 nuts loosely onto each of the shaft ends to position the legs. 10. Screw one dowel pin each tightly into the rear threaded bores, thereby fixing them with the bore in the chassis. Stretching the torsion spring: 11. Push a suitable screwdriver from behind into the left-hand bore of the shaft and turn totally to the front. Grip the shaft via the middle bore with another screwdriver and turn it to approximately 15° from horizontal. 12. Tighten fast both nuts of the shaft.

2.4.4 Assembling lid and housing 13. Put lid in place. It must catch audibly into into both locks. 14. Screw on front cap screws on both sides, thereby fastening the lid tight ly to the two legs. 15. Replace one by one the two set screws in the rear bores by the remain ing two cap screws. 16. Manually release the locks. The lid should come to rest at an angle of 15-30°. If this is not the case, re-stretch using the middle bore of the shaft. Should this be impossible, the lid must be disassembled and the spring must be stretched anew! 17. If the angle is okay, secure the M8 nuts with one drop of Loctite e ach on the legs. 18. Close the lid and replace the rear cap screws on both sides by set screws. Attention! Attention! Set screws must not jut out of the legs!

19. Screw lid off and mount housing. 20. Reassemble lid as described above and check opening angle of 15-30°. 15-30°.

2.5 Assembly and Adjustment of the Drive 2.5.1 Purpose of the adjustment The temperature measurement of the Biofuge fresco is done using a slim temperature probe. The tip of this temperature probe is fixed at a very short distance to the motor cover as well as to the rotor. In order to guarantee an accurate temperature measurement, a defined distance to both rotor and motor cover is mandatory! For this purpose, the drive must be adjusted.

2.5.2 Mounting / Adjustment of the drive with help of the rotor #3243 Fasten rubber buffers to the transverse crosshead using nuts and washers. • Place transverse crosshead inside the chassis and fasten with screws such that the screws are aligned with the upper ends of the long holes. • Connect the motor to the rubber buffers using the screws and locking rings.

Adjusting the transverse crosshead • Put three cylindrical spacers with a thickness of 6,0±0,1 mm (diameter 10 to 20mm) for rotor #3243 into the evaporator. • Position the rotor onto the motor shaft and fasten with flanged nut. • Loosen the screws about ½ turn and carefully move transverse crosshead downward until the rotor rests on top of the spacers. Attention! Make sure the transverse crosshead is horizontally placed. Besides, the rubber buffers must not be stretched or tilted. • Fasten all 8 screws of the transverse crosshead.

Checking the adjustment • Replace the spacers by three 5,0±0,1 mm thick spacers (diameter 10 to 20mm) for rotor #3243. Fasten rotor again as prescribed. • Turn rotor manually. The motor is correctly mounted if the rotor does not touch the spacers. If it does, the adjustment must be repeated. • Remove spacers and secure screws with a drop of screw lock. • Reinstall centrifuge and rotor as prescribed and do a test run.

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.

EXERCISE CAUTION when measuring etc. •

3.2.2 Intermediate Circuit with Brake Path and Frequency Converter Intermediate Circuit 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 bridge rectifier (4 diodes) and one reservoir capacitor which is softly charged, continuously supplied during operation and slowly discharged after power off. Brake Path Electrical power is fed back into into the intermediate intermediate circuit during motor deceleration (motor acts as generator). This braking power is transformed into heat by two big brake resistors (parallel connected) on board so that the intermediate circuit voltage does not rise to an excessive level (see section 2 test points on main board). The brake resistors are switched into the intermediate circuit by a fast switching transistor (pulse width modulation). This transistor is voltage dependant controlled by a selfacting stage (closed loop). Frequency Converter The motor is 3-phased provided 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, over temperature and over voltage.

5.6.2 Fans (310) Both fans (ventilators) aspire air for cooling from the front through the ventilation slots and the wire mesh. The air is forced past the power transistors, the lamellae of the condenser and the motor windings and exits through the rear ventilation slots. Take care that the Armaflex cut (218) seals the condenser tightly against the casing. Otherwise the circulating air may form shortcuts via the slots or openings, thereby reducing cooling power and longevity of both drive and compressor. Remove the casing (see 5.1.3) Set the wires free from cable harness and open the cable retaining strap. Remove the fastening screws (311), take out the defective fan. Pull off the wire connectors, unscrew the protecting earth conductor and remove the defective fan. Transfer grounding conductor to the new fan and reconnect the wires.

5.6.3 Components of the Cooling Cycle When working on the cooling cycle the general guidelines regarding the handling of refrigerants must be observed! The compressor oil must be recycled, too, in case of a compressor break down! Refrigerant: R134a (CFC-free) Filling quantity: 135 g (individually the compressor labelled amount is relevant) There must not be used any kind of hoses, armatures and manifold gauges which are already contaminated with CFC based refrigerants. Otherwise the compressor oil will become an aggressive condition and will destroy the compressor in a short time. Procedure for replacing defective components of the cooling cycle Mount a pinch valve onto the compressor's service line (suction line) Suck off the refrigerant and recycle it If the compressor (340) is defective, let the oil run out into a bowl and recycle it, too. Unsolder the defective component(s) and replace additionally the dryer cartridge (325). Let a little amount of dry nitrogen gas stream through the tubes when soldering Do the evacuation and refill the system with the exact amount of refrigerant via a new external dryer (check amount with a balance or filling cylinder)

• • • • • •

The pinch valve must not be left on the line! Close the system hermetically (solder close) and fix the service lines using cable ties with a little drop to let the oil run back after transportation. Re-assemble the unit in reverse order and test the cooling system (see Servicing Schedule).

Record the values in the temperature section of the certification form. Determine if the temperature values recorded meet the specifications on the form. If the specifications are met, proceed to the next section. A re-calibration of the instrument is not possible. Initial the temperature section. To pre-cool the rotor select half maximum speed. •

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 re-calibration 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 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.
