7.3 Rotor detection
Rotor detection is performed after starting a centrifugation run.
The centrifugation run is cancelled after rotor detection if the rotor code
of the rotor is being read in for the rst time. The rotor code (R) and the
newly detected rotor's maximum speed (maxRPM) permissible for the
centrifuge are displayed.
1. Press any button after the rotor has stopped.
🡆 The maximum permissible number of run cycles (
‘Cyc lim’
) is dis-
played.
2. Set the maximum permissible number of run cycles of the rotor or the
bucket.
Every rotor in a centrifuge has a maximum permissible speed.
The maximum rotor speed (
‘ROTOR MAX’
) is displayed briey after the
centrifugation run has started.
The centrifugation run is cancelled if the set speed is greater than
the permissible maximum rotor speed. The permissible maximum rotor
speed is displayed.
Adjust the speed to the maximum rotor speed.
If the cycle counter is enabled, the remaining number of run cycles (cen-
trifugation runs) of the rotor code used is displayed briey after opening
the lid.
