1Description of the Centrifuge
The centrifuge range is composed of:
References Model
AFI-CI060V Ventilated, 120V / 60Hz
AFI-CI060V-E Ventilated, 230V / 50-60Hz
AFI- CI060R Refrigerating, 120V / 60Hz
AFI- CI060R-E Refrigerating, 230V / 50Hz
The centrifuge is composed of:
•an electrical block, called Ogival Control Center
•a lock
•a motor
•a ventilation or refrigeration system (depending on the model)
•a lid
It is equipped with one or several rotors:
•Free or swing-out
•Angular
The free rotors are fitted with:
•Buckets
•Tube adapters or inserts
•Watertight lids
Some angular rotors are equipped with tight fitting lids.
1.1 Electronic Control Center / Block
Electronic control center is included in an ogival block.
It includes touch buttons, a knob, a lid opening button, as well as the microcontroller electronic board,
It is also equipped with RGB LED lighting for various color lighting.
There is no provision for changing the elements composing the Control. It is a complete separate part. In case of
defective element, a standard exchange of the complete Control Center must be considered, which facilitates the
restoration of the centrifuge.
The power electronic board is located inside the centrifuge body, on a power electronic “rack”. This can be ordered
independently for replacement.
Start/Stop Button
There is no main electrical switch on ISA centrifuges.
When connected to power supply through the power cord, the centrifuges turns ON.
To switch to stand-by mode, press & hold START/STOP button.

1.3 Motor
Three phases induction motor powered in variable voltage & 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. Centrifuge then display error code “# 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 Temperature probe
It is located in the bowl gasket, and therefore in the rotor airflow when the rotor is in rotation.
The measurements are only taken when the rotor is rotating.
sensor is a PT500 class A probe.
At the beginning of a cycle the displayed temperature is the air temperature (air around the sensor), once target
temperature reached, the displayed temperature is that of the samples.
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.
1.6 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.
The systematic minimum threshold detection is: 9 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 9 gr.
Cf. § 3.2Unbalancing Sensitivity Setting for the procedure to adjust the imbalance detection threshold.
1.7 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.

Original Instructions - Rev.1.0 Service Manual– ISA Centrifuges 10/ 27
1.8 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 3. This set will allow for
absorbing parasitic movements whatever the rotor, its load, and its speed, providing that the load is balanced.
Those 3 shock absorbers are placed vertically between the motor and the stabilizer bed.
1.9 Refrigeration System
The refrigerating model allows the maintenance of a sample at its initial temperature, while undergoing a rotation.
Take care to let free space around the centrifuge for airflow renewing.

3.2 nbalancing Sensitivity Setting
The centrifuge has a reaction to the load balancing faults which may be different depending on the media on which the
centrifuge is placed. Check following items before any setting adjustment:
-Balanced bucket loadings,
-Installation instructions, conform to User Manual,
-Visual inspection,
-Cleaning rotor trunions & buckets for proper bucket balancing,
-Lubricating rotor trunions.
Required material:
7 grams weight
10 grams weight
Operating:
1. Place a 7 grams weight into a bucket, as unique load of the swing-out rotor.
When processing a 2000 rpm set speed cycle, no error code must appear.
2. Place a 10 grams weight into a bucket, as unique load of the swing-out rotor.
When processing a 2000 rpm set speed cycle, the error code #02 must appear.
3. Then, reproduce 2x each of previous test: the result must be unchanged.
If the tests are not conform, adjust A1 advanced parameter as following:
The higher the value, the bigger imbalance is tolerated. (Default value: 350).
Caution Always check a 10 grams imbalance is detected.
An excess imbalance tolerance could deteriorate the centrifuge.
Remark:
Along this adjustment process, Parameter b20 can be used to check the measured vibration level (last centrifugation
cycle). This can help optimizing the threshold setting.
