Unbalancing sensitivity detection
The centrifuge has a reaction to the load balancing faults which may be different depending on the media on which the
centrifuge is placed. A calibration of the imbalance sensitivity is therefore necessary during installation.
Required equipment: Use the reference balancing kit AFI-71122002.
Visual
Instruction
Control
Access the unbalance sensitivity calibration menu.
Equip a rotor swing-out and its 4 nacelles in the centrifuge.
Remove the inserts of the nacelles.
Low threshold
1.
Place the round 15 gram weight in one of the nacelles and
close the lid,
2.
Press the button “15gr”
3.
The rotor accelerates until it stabilizes.
4.
The centrifuge shakes, then the rotor slows down.
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 nacelle.
8.
Proceed in the same way as for the 15 gram weight.
9.
The low threshold is then determined. (e.g. “520”)
10.
Open the lid and remove the 25 gram weight.
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:
12.
Place the 15 gr + 10 gr weights in a nacelle.
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.
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.
