Mögliche Beschädigungen an Bedienteilen der Centrifugen 5417 C Durch Rückmeldungen über unsere Service Info Line (SIL) aus den Märkten wurden wir auf einen möglichen Fehler an neuen Bedienteilen der Centrifugen 5417C aufmerksam gemacht. Beim Abziehen der Schutzfolie verblieben offensichtlich Kleberreste auf der Oberfläche des Display. In vielen Fällen ließen sich diese Rückstände mit handelsüblichem Waschbenzin entfernen. In einigen Fällen war jedoch die Oberfläche des Display bereits angegriffen, so dass das Bedienteil ausgewechselt werden musste. Als Verursacher dieser Beschädigungen wurde ein Silikon-Lösungsmittel in einem Glasreiniger ermittelt. Der entsprechende Fertigungsprozess wurde bereits geändert. Sollten Sie ein Display vorfinden, bei dem sich die Kleberreste nicht rückstandslos mit Waschbenzin entfernen lassen, berichten Sie uns diesen Fall bitte unter Angabe der Gerätenummer per SIL. Wir werden das Bedienteil umgehend austauschen.
Possible damage to control panels of the Centrifuge 5417 C Due to feedback obtained from the markets through our Service Info Line (SIL) , a possible error involving the new control panels of the Centrifuge 5417C has been brought to our attention. When the protective foil is pulled off, it seems that adhesive residue remains on the surface of the display. In many cases this residue can be removed with commercially available petroleum ether. However, in some cases the surface of the display had already been damaged, meaning that the control panel needed to be exchanged. A silicone solvent in a glass cleaner has been determined to be the cause of the damage. The production process involved has already been changed. If you should discover a display where it is not possible to completely remove the adhesive residue with petroleum ether, please report this case to us with the device number via an SIL. We will replace the control panel immediately. MST/Mo/2005-08-18

3 Error lists / Troubleshooting Error list Display
Error
Error 1
Centrifuge brakes.
Cause
1. Error in measurement system for rotational speed. No rotor recognized. 2. Magnet assignment of the rotor coding is defective. 3. Only two magnets recognized (half rotational speed). 4. Incorrect voltage version has been set. 5. A loose rotor has been recognized (rotor may have tightened during acceleration).
Error 2
Centrifuge does not start or brakes.
Imbalance idle value is outside the permitted limits, or the measuring value is incorrect. Incorrect idle value must be applied for at least three seconds. 1. Sensor value < 0.5 V or > 4.5 V; sensor is defective. 2. Idle value is ± 220 mV outside the stored idle value (SE15).
MMT/MMWT/ 1111
Test/Solution
Use another rotor. If the error does not recur, check the coding ring of the rotor. Check whether the magnets are complete and in good condition. Check the rotational speed sensor with customer service program 8: – Four pulses per rotation; test with service program 8 (SE 8) possible. – Rotor ratio, test with service program 8 or customer service display 5.
Customer service program 6 shows the stored idle value and the current idle value. Test: Current idle value changes when the motor axle moves. If it does not change, the sensor is defective or the magnet bracket is missing. When the centrifuge is stationary, the current idle value must be within the limits of ± 25 digits (equivalent to ± 220 mV) of the stored idle value.

If the SOFT and SPEED-PLUS keys are pressed simultaneously, the centrifuge switches over to the service display mode. This does not depend on the current centrifuge operational mode. The centrifugation runs remain unaffected. The displays are run through by pressing the SOFT key. During the service display, a SOFT switchover is not possible. In the case of error, the display automatically jumps to "current error message". It is then possible to switch to different displays. The display "current error message" shows the current error and the error location. For Error 6, the converter error number is also shown.

3 Error lists / Troubleshooting 10) Imbalance calibration
General information: Imbalance calibration requires two calibration weights. Two reaction tubes of 1.5 ml or 2.0 ml are filled and balanced with the corresponding material (e.g. quartz sand). The tube for the lower calibration value must have a total weight of 2.3 g ± 0.1 g. The total weight of the vessel for the upper calibration value is 3.8 g ± 0.1 g. If the imbalance calibration is carried out with fixed-angle rotor F 45-30-11 or FA 45-30-11 (rotor number R0), the determined limits are converted for the swing-bucket rotor and the PCR rotor (rotor number R1) as well as the 24-position rotor (rotor number R2). However, if the calibration is carried out with a different rotor than the 30-position rotor, the determined values are valid for this rotor only; the values cannot be carried over to another rotor! The imbalance calibration is carried out without rotor lid. •
Install a flyweight of 2.3 g (lower value) into the rotor.
•
Close the centrifuge lid.

Electrical test See "Description: Device check for centrifuges".
ME 07
Compulsory testing in Germany (BGR 500): In Germany, centrifuges with a nominal power consumption (without refrigerating system) of more than 500 W or a kinetic energy exceeding 10,000 Nm are subject to compulsory testing in accordance with accident prevention regulation BGR 500 (formerly VBG 7z).
This applies to the following centrifuges by Eppendorf AG: Centrifuge 5804/5804R/5810/5810R/5810 RA. This means that a periodic inspection must be completed in the operational state at least once a year, and in the disassembled state at least every 3 years. Rotors with a kinetic energy not exceeding 10,000 Nm are not subject to compulsory testing, but because of the fact that they are used in Centrifuges 5804/5804R/5810/5810R/5810 RA, all rotors (swing-bucket rotors with buckets) must be included in the tests. The centrifuge operator is, on his own authority, responsible to provide proper evidence to document the required tests.

Frequency converter assembly group This assembly group is the core of the machine, as the drive of the three-phase asychronous motor and the power supply for all assembly groups are generated in the frequency converter. This PCB consists of the following main assembly groups:
• Input power supply unit with PFC regulation • Switching power supply unit for voltage supply for the control assembly groups • Power unit for motor drive and brake chopper • Computer core with interface to the operating PCB Non-refrigerated version (5417 C): The PCB is screwed onto the base plate of the machine.

12 Descriptions Power unit for motor drive and brake chopper The frequency converter transforms the single-phase alternating current into a three-phase alternating current for driving the three-phase asynchronous motor without collectors. The converter is equipped with a basic data set, which can be updated at any time to the necessary parameters via the interface. With this type of control, it is possible to set acceleration and braking cur ves as desired and to minimize power consumption and power loss. The resistors required for the brake chopper operation are connected to S402. The converter contains the electronic braking circuit, which uses the external braking resistors in order to reduce the excess energy which is generated (motor acts as generator). Computer core with interface to the operating unit PCB The core of the computer is formed by the Siemens Controller C504, which provides complete central control of the drive (data communication for operation, generating a rotary field, or monitoring current and voltage). The data communication between control and converter is based on a serial data transmission (RS 232) via the connection cable to X4 or X604. This makes it possible to modify the converter parameters for an optimal centrifuge run even when the run is taking place. During the run, there is a continuous telegram exchange, so that also converter errors can be analyzed immediately. The data output to the converter is carried out via port 6.1 and the data acceptance from the converter via port 3.0 of the processor on the keypad.
Display/operation assembly group This assembly group consists of a matrix with an adhesive front foil and a PCB which is equipped on both sides. The following parts are integrated onto the PCB:
• Short-stroke keys for operation and for entering parameters • Seven-segment LC display with background illumination • Computer core (Siemens-Controller SAB 80C515A) (IC1), OTP (IC2), address latch (IC3) and EEPROM (IC4)
• Peripheral electronics for processing signals (sensors) and data communication The processor operates with a clock frequency of 12 MHz which is generated by means of an oscillatory circuit. This circuit consists of an oscillator switch in the processor and an external 12 MHz quar tz (Q1) with two 22 pF capacitors (C29, C30). The operating system of the centrifuge is stored on the OTP. The EEPROM makes it possible to store current operating parameters, such as rotational speed, duration of the last run and operating hours. This data remains saved even after the centrifuge has been switched off and can be called up again after the centrifuge has been switched on again. All control signals and sensor signals (except for lid inquir y) are transferred to or from the converter via a 26-pin flat-band cable (X4). Please note that the adaptation of the sensor leads at the converter PCB differs according to whether 5417 C or 5417 R is used. However, the signal processing on the operating LP is identical.

12 Descriptions Rotational speed determination and rotor recognition These functions are carried out with the aid of a unipolar Hall sensor (TL4905L). This sensor consists of a 3-pin flat-band cable and is soldered to a sensor board located below the motor covering in the rotor chamber. As the output is designed as an open-collector, R13 acts as "pull-up" resistor and supplies a defined signal at the processor port (e.g. if a cable break occurs between the sensor and the keypad PCB). R15 and C19 help to reduce interfering pulses (low-pass filter) and IC6 helps to improve the steepness of the pulse.
Active mechanism Under influence of a magnetic field, the output of the sensor becomes conductive against ground. When the rotor is spinning, the magnetic strips on the rotor move past the Hall sensor and generate "LOW" pulses, according to the width of the magnet. These impulses are evaluated as rotational speed pulses. Four magnets of an identical width are used for each rotor, with the width used depending on the rotor model. This enables clear coding of the rotors. The rotational speed has no effect in this regard.
Imbalance determination Imbalance determination is carried out by a system which analyzes the distance between a magnet fastened to the motor and an analog Hall sensor (UGN3503U). The sensor is integrated on PCB "Imbalance Detection", which amplifies the Hall signal. The height and polarity of the induced voltage corresponds to the strength and polarity of the magnetic field. Depending on the position of the motor axle, the magnetic field of the magnet influences the sensor with different field strengths. In turn, this changes the induced voltage at the output. This enables an analysis of the imbalance which is reproducible exactly. The assembly is either directly mounted on the converter PCB (5417 C) or mounted on the motor plate and adapted to the converter PCB (5417 R) via plug X601. The amplified sensor signal reaches the keypad PCB (X4) via X604. It reaches the control processor (pinport 6.0) via an RC combination, which functions as a low-pass filter and dampens interfering pulses. At this processor, it is transformed into a signal which can be analyzed by the internal A/D converter. This assembly group is installed at a distance of approx. 10 mm from the permanent magnet. In order to achieve a sufficient signal, the operating voltage of the OPV on the imbalance PCB is 8 V. The signal is generated on the converter PCB from the 24 V supply by means of a Z-stabilization. Since the analog voltage on the processor pin of the operating unit PCB must not exceed 5 V, the voltage is limited by a 4.7 V Z-diode (ZD1).

12 Descriptions Temperature determination (Refrigerated Centrifuge 5417 R only) Rotor chamber temperature In order to measure the rotor chamber temperature, an NTC resistor is used which is encapsulated in a sleeve and located on the base of the rotor chamber. The sensor (NTC 10 k / 25 C) changes its resistance in accordance with the temperature. The connection cables are connected to plug X601 of the converter PCB. The signal reaches the operating unit PCB via X604, where it reaches the analog por t (PORT 6.1) of the processor with the voltage divider (R12) and the voltage modification is registered and analyzed. °
Condenser temperature The condenser temperature is measured with the aid of an NTC resistor which is fastened to the port of the compressor. This sensor (NTC 10 k / 25 C) serves as protection against overtemperature for the compressor and as control element for the rotational speed control of the condenser fan. It is connected to the analogue por t of the processor (PORT 6.2) via X602 and X604 and a voltage divider (R14). The measurement is carried out in proportion to the rotor chamber temperature. °
Lid magnet selection and lid query The lid latch mechanism contains a solenoid magnet and two switches, which are mounted in a separate assembly group in the casing. The solenoid magnet is a DC magnet which is supplied with rectified mains voltage by the converter PCB. Two solid-state relays (triac with optocoupler port), which are located on the converter PCB, serve as "mains" switches. X4 and X604 of the keypad PCB serve to open the triacs, which releases the magnet. A pulse of 200 ms in length opens the lid. When the machine has come to a standstill and the "OPEN" key has been pressed, this pulse is sent from the processor pin (P5.2). The signal distance of this pulse is connected to a monoflop circuit (IC7, C27, R39), which stops opening pulses, if there are still rotational speed pulses. This circuit serves as an additional protection which prevents the lid from being released unintentionally before the rotor has come to a standstill. The lid position query has an important safety function, in order to prevent the machine from starting when the lid is open. One microswitch recognizes the position of the locking and the other switch recognizes the lid position. Refrigerated version (5417 R): Second microswitch at the ejector of the lid recognition. Non-refrigerated version (5417 C): Second switch is a Reed sensor that is activated by a magnet located in the lid. However, in both machines, both switches must be closed in order to signal that the machine is ready to operate. This means that both processor ports (P3.4, P3.5) are connected to GND.
