Cycle counter

The period of use of certain rotors and hangers is limited to a maximum number of run cycles (centrifugation
runs). The rotors and hangers in question are labeled with the maximum permissible number of run cycles.
The centrifuge is equipped with a cycle counter, which counts the running cycles (centrifugation runs) of the various
rotor codes (see also the "Rotor detection" chapter).
After each centrifugation run, while the lid is unlocking, the remaining number of running cycles (centrifugation runs)
will be briefly displayed.
Example:
PROG RPM t/min:s
If the maximum permissible number of running cycles has been exceeded, the following is displayed every time the
centrifugation run is started, and the centrifugation run must be restarted.
PROG RPM t/min:s
If this display appears:
PROG RPM
the rotor or hanger in question must be immediately exchanged for a new rotor/hanger for safety reasons.
After the rotor/hanger has been exchanged, the cycle counter of the respective rotor code must be reset to zero
again (see "Resetting the cycle counter to zero" chapter).
If the rotor code of a rotor is read in for the first time by the rotor detection, the centrifugation run then stops
automatically after rotor detection. The rotor code (R) and the maximum speed (maxRPM) of the rotor permitted for
this centrifuge are displayed.
Afterwards, the maximum permissible number of run cycles of the rotor/hanger must be set.
In the case of swing-out rotors, the maximum permissible number of run cycles of the hangers must always be
set.
The maximum permissible number of run cycles of the rotor/hanger must be set as follows.
Display after rotor detection.
R : Rotor code of the rotor.
maxRPM : The maximum speed of the
rotor permitted for this centrifuge.
