1.2 Lock
The lock consists of a media on which the following are assembled:
1) Micro contact / Micro switch No. 1:
It detects the open position of the lock.
The deadbolt presses on the micro switch blade when
the lid strike plate is completely released.
2) Micro contact / Micro switch No. 2:
It detects the closed position of the lid.
The guide finger comes in contact with the micro
switch blade when the lid is closed.
This signal stops the gear motor command.
A “Lid lock tempo” timer allows for adjusting the stop
for proper locking.
3) Magnetic sensor:
It detects the approach of the lid. The integrated
magnet in the lid strike plate allows for starting the
gear motor command.
4) Deadbolt:
It pivots to mechanically immobilize the lid.
5) Crankshaft:
It actuates the deadbolt through the motor reducer.
The locking position is obtained when the crankshaft
and the deadbolt form a 90 degree angle.
This position is marked by the trace on the visible face.
6) Trace from the locked position
7) Motor reducer:
It rotates counter-clockwise to close and clockwise to
open. It is supplied with a voltage of 24 V.
1.3 Motor
It is a three phase induction motor powered in variable frequency.
It has an integrated over temperature sensor. It measures the heating of the internal motor winding, and sends a signal
from 130 degrees Celsius. It then sends the message “ERROR 04”.
1.4 Speed Sensor
The speed sensor is a Hall Effect magnetic sensor, placed under the motor. Six (6) magnets with alternating poles are placed
on a rotating disc. The sensor measures the frequency of passage of the magnets, to determine the speed.

1.5 Tachometer Board
The tachometer board is composed of:
1) The connection to the tachometer sensor
2) The connection to the Control Center
3) The accelerometer: It detects the vibrations emitted
by the centrifuge. The triggering threshold is set by
the menu for setting the sensitivity to the imbalance:
see §. 0
4) The accelerometer is perfectly maintained by the 5
mounting points.
1.6 Temperature Probe
It is located under the lid, and therefore nearest to the samples when the lid is closed and the rotor is in rotation.
The measurements are only taken when the rotor is rotating.
It is a PT500 class A probe.
During a centrifugation cycle, the temperature displayed on screen is that of the sample.
Before being centrifuged, the sample must be brought to the program setpoint temperature.
Use either an oven, or a refrigerator to bring it to the desired temperature.
The centrifuge is designed to maintain the temperature during a rotation cycle.
1.7 Imbalance Sensor
In the case of a load presenting an imbalance, the oscillations caused will be higher than the centrifuge’s own vibration.
The vibration sensor then intervenes to detect the movements of the centrifuge. This sensor is an electronic accelerometer.
It is placed at the level of the tachometer board, located to the side of the shield, and sends the information to the
microcontroller board.
The systematic minimum threshold detection is: 25 gr. The detection results in an immediate shutdown of the power supply
to the motor, and a slowdown of the rotor free wheel.
This threshold is adjustable according to the media on which the centrifuge rests, in order for the imbalance sensor to
always be triggered with a minimum imbalance of 25 gr see Section 3.3 for the procedure to adjust the imbalance detection
threshold.
1.8 Gas Spring
A single cylinder allows the opening of the lid when it is released by the lock. It is a gas cylinder, fitted with a spring. This
spring allows a better relaxation at the opening start. The cylinder should open the lid without causing rebound of the latter
at the end of travel.
1.9 Absorption of Vibrations
Any system has its own resonance frequency, which will cause oscillations. The dissipative elements of these oscillations,
which translate into vibrations, are anti-vibration mounts, numbering 4, coupled by an absorbent foam. This set will allow
for absorbing parasitic movements whatever the rotor, its load, and its speed, providing that the load is balanced.
Three (3) of these mounts are placed vertically between the motor and the stabilizer bed.
The 4th mount acts horizontally. It is located under the machine frame.
1.10 Ventilation System: Ventilated Model
The ventilated model allows for heat exchange between the inside of the centrifugation bowl and the ambient air. The air
inlets are installed in the lower part of the lid. This ambient air is sucked in and enters the bowl by the central part of the
lid.
During rotation, the friction between the rotor and the air causes overheating. The hot air is expelled by the circular part
under the lid. A circuit allows this air to descend through the centrifuge body, by the duct located on the right, near the
hinge. A silencer allows you to evacuate the air from the rear, under the unit. The heat caused by motor rotation is also
evacuated by this conduit.

1.11 Refrigeration System: Refrigerated Model
The refrigerated model allows the maintenance of a sample at its initial temperature, while undergoing a rotation. It is
possible to maintain a temperature from -10°C to 40°C.
Maximum performance for an ambient temperature of 20+ /- 2°C, with the rotor RX500 and the buckets BX500:
2. 0 Liter: continuous maintenance of 4°C at 4200 rpm,
3. 0 Liter: continuous maintenance of 4°C at 3600 rpm,
1.12 Frame
It is a one-piece frame: The safety shield allowing for absorbing the energy deployed by the rotor in the event of an
accident is directly visible from outside the machine. This allows you to limit the parts, and the sources of vibration.
1.13 Lid: Ventilated Model
The lid is fitted with an anti-vibration mount in anterior position, allowing for stabilizing it in the closed position.
A single strike plate allows the lock to close the lid, immobilizing it with a motorized deadbolt.
A guide finger provides additional safety when closing the lid.
The lid of the ventilated model has a fresh air inlet circuit, and a hot air outlet circuit.
1.14 Lid: Refrigerated Model
The lid is fitted with an anti-vibration mount in anterior position, allowing for stabilizing it in the closed position.
A single strike plate allows the lock to close the lid, immobilizing it with a motorized hook.
A guide finger provides additional safety when closing the lid.
The lid of the refrigerated model allows you to maintain the sealing of the bowl when the latter is closed.
It is fitted with a removable temperature sensor.
A porthole in the central part allows the tachometer control of the rotor using an optical tachometer.

3.6 Information Update
Caution: This information concerns the serial numbers of the electronic boards fitted on the centrifuge.
In case of changing an electronic board, these values should be changed:
Changing the Control Center: 2 numbers should be detected:
the number concerning the microcontroller board, and that of the display card Changing the
tachometer board
The information corresponds to technical
information about the computer software
and components constituting the device.

The values are used to determine the age of the device and the rotating accessories. Changing values should ONLY be done
in the case of an exchange of the control center. The values to be set must be identical to those recorded in the faulty
control center. It is therefore necessary to record the values before removing the faulty control center.
If the values are lost monitoring the life of the rotor will not be correct. A rotor may therefore be used beyond their
maximum lifespan. This causes a DANGEROUS situation for users and machine. In case of inability to access data from the
defective control center these values can be retrieved by the factory.
Enter the counters modification menu
Press the item to change.
The input keyboard then appears.
Fill in the value recorded from the old control
center.
Repeat this for all counts.
Exit
3.8
This alarm can protect the samples subjected to excessive heating of the air with respect to the set temperature. In case of
triggering of the alarm, the cycle is aborted. ERROR 3 A message is displayed and a buzzer starts.
Entering the overtemperature alarm menu
Adjust the desired value.
The default is + 10° C.
The value is adjustable between
+ 5° C to + 20° C.
Example: for a 10 ° C setpoint when the over
temperature threshold is set at 5 ° C, the alarm
will sound if the air temperature is> 15 ° C
Exit
Note: If the sample temperature exceeds 43 ° C, but also if the temperature of the air inside the bowl becomes
higher than 50 ° C, then the cycle is aborted with the message ERROR 3.
3.9 Loading the Firmware
The centrifuge is controlled by 2 firmware applications:
•A firmware application called “Display firmware”.
It is located in the screen board.
It manages a HMI (Human Machine Interface), and visual screens.
•A firmware application called “Centrifuge firmware”.
It is located in the microcontroller board.
The latter defines the behavior, and the interactions between the different parts of the centrifuge.
It is necessary to use the programming cable, supplied with reference CTB0311 “Software Programming”.

3.10 Factory Reset
After loading a new version of software microcontroller, it may be necessary to perform a factory reset, which returns the
device to factory configuration. This deletes the following data:
- Lock setting (a default is recorded)
- The imbalance calibration
- User programs
- The error counters (reset to 0)
- The serial numbers of the unit and electronic cards
Access the factory reset menu
"Warning: Return to factory settings All settings
of the user, and programs will be lost.
Continue?"
OK to continue
"Do not power off unit during reset."
Wait until the following message.
Turn off & turn on the unit.
3.11 Clear Counters
The counters are used to determine the age of the device, and the rotating accessories. In case of resetting these
counters, monitoring the life of the rotor will not be correct. A rotor may therefore be used beyond their maximum
lifespan. This causes DANGER for users and machine.
This menu is primarily used in the factory.
Access the factory reset menu
"Warning: This will erase all internal counters,
including centrifugation cycles counters, and
error counters. This should be achieved in
specific cases. Keep a record of the current
settings before proceeding. Continue?"
OK to continue
