Automatic rotor identification
The centrifuge automatically identifies the rotor that is being currently used.
• If the system identifies a different rotor than the one that is set and if
there are no different buckets for this rotor, the rotor input will be
adapted automatically. The system will not display a message.
• If the system identifies a different rotor than the one that is set, and if
there are different rotor/bucket combinations for this rotor, the system
will automatically identify the correct rotor and select the rotor/bucket
combination with the lowest speed. The system will display a
corresponding message so that the combination can be adapted
manually.
• If the system cannot identify the rotor, a message will be displayed. The
rotor cannot be used in the centrifuge.
This prevents the maximum permissible speed from being exceeded.
Acceleration
This function is used to select an acceleration curve. One can select a
linear rise (curves 0-9) or a quadratic rise (curves 10-19). The acceleration
curves 20-29 can be programmed as desired (see chapter 11.3 -
"Acceleration and deceleration curves").
Deceleration (brake)
This function is used to select a curve that decelerates the centrifuge to a
standstill. Deceleration curves are inverted images of the acceleration
curves and are labelled with identical numbers. Deceleration curve no. 0
represents a brakeless deceleration.
