Centrifugation

When the centrifuge is running, according to IEC 61010-2-020, no persons, dangerous substances or objects
may be within the safety margin of 300 mm around the centrifuge.
If the permissible weight difference within the rotor loading has been exceeded, the drive shuts down during
the start-up, and IMBALANCE is displayed.
If the speed in the selected program is higher than the maximum speed of the rotor (Nmax), it will not be
possible to start a centrifugation run. The message N > ROTOR MAX will be displayed (see Chapter "Faults").
A centrifugation run can be stopped at any time by pushing the key
It is possible to switch over between RPM and RCF display at any time using the
working with the RCF display, it is necessary to enter the centrifuging radius.
If OPEN OEFFNEN is displayed, a further operation of the centrifuge is only possible after opening the lid
once.
If the rotor has been changed, no centrifugation run takes place and this display is shown, e.g.
Rotor 4 Nmax= 4500 R=184 mm (see chapter "Rotor recognition").
Operating errors or faults that occur are shown symbolically in the display (see Chapter "Faults").
• Switch on the mains supply switch. Switch position Ι.
•
Load the rotor and close the centrifuge lid.
