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 §. 3.3
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 (Lisa model), or double (Loreena model) 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.

Original Instructions - Rev.1.4 Service Manual–Lisa / Loreena Centrifuges 11/ 41
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: Refrigerating Model
The Refrigerating 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 RX625 rotor (equivalent to RX500
rotor) and the BX625 bucket (equivalent to BX500 bucket):
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.Lid : Refrigetaring Model
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 : Refrigerating 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 Refrigerating 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.

5. The low threshold is then determined. It
appears under the button “15 gr”. (e.g.
480)
6. Open the lid and remove the 15 gram
weight.
High threshold
7. Place the 25 gram weight in the same
bucket.
8. Proceed in the same way as for the 15
gram weight.
9. The low threshold is then determined.
(e.g. “520”)

Average
11. Press on the Next button to average the
setting.
(e.g. [480+520]/2 = 500 )
The average value is displayed.
By default, the factory setting value is
500.
Check
The following steps are compulsory.
High threshold:
Do not adjust this threshold with a weight
greater than 25 gr. This would cause a breach
of warranty. The appliance has been
dimensioned for a maximum threshold of
25gr.
12.Place the 15 gr + 10 gr weights in a
bucket.
13. Start the cycle. 2000 rpm / 1 minute / 9
Acceleration / Braking 9
14. The centrifuge must stop during the
acceleration, and display the message
ERROR1:
The 25 gr imbalance is not tolerated.
Repeat the High threshold check 3 times:
ERROR1 must appear each time.
Low threshold:
15. Leave only a weight of 15 gr in a bucket.
16. Start the cycle. 2000 rpm / 1 minute / 9
Acceleration / Braking 9
17. The centrifuge should achieve the
desired speed and then slow down and
stop without the following error message
appearing: The 15 gr imbalance must be
tolerated.
Repeat the Low threshold check 3 times:
Each cycle should take place normally.
Note : This setting value is viewable in
HOME -> INFORMATION menu, at

The lock is in the locked position when the axis of the crankshaft and the oblong hole of the bolt are
perpendicular. A marking is carried out on the visible face, corresponding to this position.
Visible face - when the front panel is removed
Locked position identification marking
Internal face - after lock unit extraction.
Perpendicular position of the 2 axes
3.4.2 .Lock Operation : LOREENA Model
Locking steps : :
The lid is lowered manually.
The left strike of the cover (1) is detected by the approach sensor
(2).
The motor reducer (6) starts.
The open position sensor (8) changes to state 0.
The hooks (7) drive the 2 latches down.
