4 Description of the centrifuge
This microprocessor controlled centrifuge mainly consists of the following components:
• Control panel (A2)
• Electronics (A1)
• Motor (M1) with speed sensor (B1) and holder of the magnet for the imbalance detection
• Motor-driven lid lock (A4)
All electronic components are on mains, except the speed sensor (B1).
4.1 Control panel (A2)
The control panel (A2) have control tasks, it disposes of the following characteristics:
• Keys for input of the operation parameters.
• LCD-display
• Transmission of the signals to the electronics (A1) via the interface.
• Storing the machine version and the brake setting.
By means of the machine version the electronics (A1) is informed which kind of centrifuge has to be controlled.
Then the electronics (A1) takes the corresponding values from the ROM, e.g. max. speed, acceleration and
deceleration ramps, adjusted value for the imbalance switch-off.
• Communication with the electronics (A1) via TTL interface.
• Monitoring the speed signal and the speed measurement.
If over or under speed is detected the motor will stop.
• Status indication with a green LED:
Standby: The LED lights up
Centrifugation run: The LED flashes slowly
Case of error: The LED flashes quickly
The power supply for the control panel (A2) is transmitted from the electronics (A1) via the flat ribbon cable:
Pin 1 GND
Pin 4 +5V
4.2 Electronics (A1)
The electronics (A1) is a combination of:
• Control
• Voltage supply
• Frequency converter
The electronics (A1) carries out the following tasks:
• Power supply 15 V, DC for the speed sensor (B1).
• Power supply 5 V, DC for the control panel (A2).
• Control of the motor:
– Generating the motor power supply
(three-phase current with variable frequency and voltage)
Functional description: The mains voltage is rectified, smoothened and chopped into a pulse width pattern
in three bridge elements with a microprocessor.
– Monitoring the motor current.
– Evaluating the speed sensor pulses (1 pulse per revolution).
If over or under speed is detected the motor will stop.
– Evaluating the overtemperature switch in the motor (M1).
• Evaluating the imbalance sensor.
• Controlling the motor-driven lid lock (A4).
• Communication with the control panel (A2) via TTL interface.
• Error evaluation.
• Status indication with a yellow LED:
Standby, centrifugation run: The LED lights up
Case of error: The LED flashes with specific errors

7/65
4.3 Motor (M1) / Speed sensor (B1)
• The motor is a 2-pole three-phase asynchronous motor (1 pair of poles).
• The motor is protected against overheating by an overtemperature switch. The overtemperature switch is
integrated in the motor and cannot be replaced.
• The electronics (A1) evaluates the overtemperature switch.
• The speed sensor (B1, speedometer) is screwed to the bottom of the motor. The speed signal (1 pulse per
revolution) will be triggered by a magnet located in the motor axle.
• The electronics (A1) monitors and controls the speed of the motor.
• In addition the speed of the motor is also monitored by the electronics (A2).
• The holder of the magnet for the imbalance detection is attached to the motor.
4.4 Motor-driven lid lock (A4)
• The lid can be opened only if the electronics (A1) has detected rotor standstill.
• After pressing the key
STOP
OPEN
the lid opens motor-driven.
• The centrifugation run can only be started when the lid is closed and the lid lock has locked. A microswitch on
the lid lock detects the position of the lid lock (open/closed) and report it to the electronics (A1).
4.5 Imbalance detection
• An hall sensor monitors the imbalance. This hall sensor is located on the electronics (A1).
• The magnet for the imbalance detection is located in a holder which is attached to the motor. The holder is
placed in such a way that the magnet is located directly above the hall sensor.
• Imbalance is detected only in running mode (run up, centrifuging and braking).
• If impermissible imbalance is detected, the motor switches off and the rotor slows down braked until it stops.
5 Troubleshooting procedures
• Fuses in installation in which centrifuge is installed are intact.
• Mains input fuses of centrifuge are intact.
• Mains voltage present at (see connecting diagram):
EBA 200:
− Connecting cable
− Appliance plug/mains switch
− Electronics (A1), plug S102L and S102N
EBA 200 S, HAEMATOKRIT 200:
− Connecting cable
− Appliance plug/mains switch on the electronics (A3), plug SL1 and SN1
− Electronics (A1), plug S100, pin 1 (L1) and pin 3 (N)
• Look for the displayed error message in chapter 6 on page 8.
• Remedy the error according to the instructions.
• Carry out a functional check after every repair and whenever a component is replaced, see pg. 48, chapter 8.

Unplug plug S101 and check the winding resistances of the motor at Pin 1, Pin 3 and Pin 5 on the cable plug.
For resistance values of the various motors, see the above figure.
– Electronics (A1) is defective.

• Error description:
– FC ERROR 61.19:
The frequency converter on the electronics (A1) detects overspeed Braked run-down of the rotor until it comes
to a standstill. The device can no longer be operated.
– FC ERROR 61.20:
The speed measurement of the frequency converter on the electronics (A1) is faulty. Braked run-down of the
rotor until it comes to a standstill. The device can no longer be operated.
• Clear error message:
Wait until the rotor has come to a standstill and the symbol (lid locked) is displayed. Afterwards, carry out a
MAINS RESET.
• Cause of error:
– Loose contact on the plug S602 or S504 / electronics (A1).

FC ERROR 61.21
• Error description:
The frequency converter on the electronics (A1) detects underspeed. Unbraked run-down of the rotor until it
comes to a standstill. The device can no longer be operated.
• Clear error message:
Wait until the rotor has come to a standstill and the symbol (lid locked) is displayed. Afterwards, carry out a
MAINS RESET.
• Cause of error:
– Motor is sluggish (bearing damage).
– Motor has a winding short-circuit (winding defective).
On the electronics (A1) on plug S101, there is a voltage of approx. 325 V DC.
Unplug plug S101 and check the winding resistances of the motor at Pin 1, Pin 3 and Pin 5 on the cable plug.
For resistance values of the various motors, see the above figure.

IMBALANCE
• Error description:
An impermissible imbalance was detected. Braked run-down of the rotor until it comes to a standstill.
• Clear error message:
Wait until the rotor has come to a standstill and the symbol (lid locked) is displayed. Afterwards, unlock the lid
or carry out a MAINS RESET.
• Cause of error:
– The rotor is unevenly loaded.
– The three rubber/metal bearings on the motor are damaged. Check the three rubber/metal bearings for wear
or cracks.
– The imbalance switch-off is maladjusted. Adjust the imbalance switch-off; see chapter 7.4.2.
– Electronics (A1) is defective.
FC ERROR 61.153
• Error description:
The imbalance system is not in working order.
• Clear error message:
Carry out a MAINS RESET.
• Cause of error:
– There is no holder with magnet fastened to the motor for detecting imbalance.
– The magnet for detecting imbalance is defective or is no longer in the holder.
– The holder is placed such that the magnet is no longer above the hall sensor.
– Electronics (A1) is defective.
– The three rubber/metal bearings on the motor are so damaged that the magnet is no longer above the hall
sensor.
