These microprocessor controlled centrifuges mainly consist of the following electrical components:

• Operating panel (A2)

• Electronics ROTINA 380 (A1) resp. Electronics ROTINA 380 R (A1)

• Motor (M1) with 2 speed sensors (B2.1, B4) and an imbalance sensor (B2.2)

• Brake resistor (R1)

• Motor-driven lid lock (A3)

• Cooling system

4.2 Operating panel (A2)

The buttons, the LCD display, the status LEDs and the acoustic beeper are located on the operating panel. The operating panel is connected with the Electronics (A1) via a 20-pole flat ribbon cable.

4.3 Electronics ROTINA 380 (A1) resp. ROTINA 380 R (A1)

There are 2 microprocessors on the Electronics. Both processors (control- and driveprocessor) are communicating internal via a serial interface.

The control-processor carries out the following tasks:

• Reading in the buttons and controlling the LCD display and the LEDs.

• Saving of 99 run programs.

• Evaluating the errors recognized by the frequency converter.

• Voltage supply and evaluation of both speed sensors (B2.1, B4, speedometer).

• Voltage supply and evaluation of the imbalance sensor (B2.2).

• Controlling the motor-driven lid lock.

• Voltage supply 15 V DC and 5 V DC for the operating panel.

• Evaluating the temperature sensors T1, T2 (B1, B3) and controlling the cooling.

• Evaluating the overtemperature switch in the centrifuge chamber.

• Status indication with a yellow LED:

All functions are all right: the yellow LED lights up

The frequency converter carries out the following tasks:

• Generating the motor current supply (three-phase current with variable frequency and voltage)

Functional description: The supply voltage is rectified, smoothened and

chopped into a pulse width pattern in three bridge elements with a microprocessor.

• Monitoring the motor current.

• Evaluating the overtemperature switch in the motor (M1).

• The braking chopper transfers the electrical energy produced during braking, from a

voltage of approx. 400 Volt, to the brake resistor in a controlled manner.

9/98

• Status indication with a green LED: Standby: the green LED lights up

Centrifugation run: the green LED lights up Case of error: the green LED flashes

If the drive-processor detects an error, it switches off the motor.

4.4 Special features

• Multiprocessor concept: The control- and the drive-processor monitoring one another. If one processor stops working, the other processor switches off the drive.

• Interface concept: The information transmission is monitored with an additional check sum.

• Hardware concept: All safety related switches are break contacts. This also ensures that loose contacts and cable rupture can be detected.

4.5 Brake resistor (R1)

• An overtemperature switch (F3) protects the brake resistor (R1) against fire. If the braking chopper has a short circuit, the brake resistor becomes hot due to the high current, and the overtemperature switch (F3) disconnects the supply voltage of the centrifuge.

4.6 Motor (M1) / Tacho system (B4, B2.1)

• The motor (M1) is a three-phase asynchronous motor with four pairs of poles.

• A speed sensor (B4, speedometer) which is screwed onto the motor receives

− the rotor code information and

− the speed information (6 pulses per revolution)

from the magnets of the tacho ring attached to the rotor.

• An additional speed sensor (B2.1, speedometer) is together with the imbalance sensor (B2.2) in one housing. This housing is screwed to the bottom of the motor. The speed signal (1 pulse per revolution) will be triggered by a magnet fixed at the motor axle. This signal is used for the release of the motor-driven lid lock.

• The Electronics (A1) monitors and regulates the speed.

− Double safety:

The drive-processor has been programmed in such a way that it switches off the drive when the speed is higher than the permissible rotor speed. Then error message "FU/CCI-ERROR 61.19 Overspeed" will be displayed.

• The Electronics (A1) monitors the rotor standstill.

10/98

4.7 Imbalance sensor (B2.2)

• An electronic sensor monitors the imbalance.

• The imbalance sensor (B2.2) and the speed sensor (B2.1) are together in one

housing, screwed to the bottom of the motor (M1).

• Imbalance is detected only in running mode (run up, centrifuging and braking).

• If impermissible imbalance is detected, the drive switches off and the rotor slows

down braked until it stops.

4.8 Motor-driven lid lock (A3)

• The lid can be opened only if the Electronics (A1) has detected rotor standstill.

• By pressing the key

STOP / OPEN

the lid opens motor-driven.

• The motor locks the lid only if both lid brackets actuate both lid switches (Ll, Lr), the position switch (Mo) for position "lid opened" is actuated and the rotor has standstill.

• The centrifuge can only be started when the lid is closed.

4.9 Cooling system

• The cooling system is a hermetical system.

• The cooling system consists of the following components:

− Compressor (M2, M2.1)

− Cooling tubes around the centrifuge chamber (evaporator)

− Condenser

− Dryer

− Fan (M3)

− Temperature sensor T1 (B1) and overtemperature switch in the centrifuge

chamber

− Temperature sensor T3 (B3) on the condenser

• In the housing of the temperature sensor T1 (B1) also the overtemperature switch is

included. With centrifuges with cooling the drive switches off, when the temperature is > 60°C / > 140°F, and with option Heating/Cooling > 120°C / > 248°F.

• The refrigerant will be cooled down with a fan (M3). The speed of the fan is controlled dependent to the temperature at the condenser.

• When opening the lid of the centrifuge, the cooling system switches off.

• When the rotor is at standstill and the lid is closed the centrifuge chamber will be

cooled on the preselected temperature, if this is lower than 20°C / 68°F. During the standby-cooling the compressor is time-cycle controlled (2 minutes ON / 3 minutes OFF).
