Cycle counter

Usage of the cycle counter only makes sense if you always use the same hanger set.
The centrifuge is fitted with a cycle counter, which counts the rotor cycles (centrifugation runs) of the different rotor
codes (see also chapter, "Rotor recognition").
In the swing-out rotors, the cycle counter is used to determine the rotor cycles (centrifugation runs) of the hangers.
If a rotor is recognized the first time, the centrifugation run is canceled. After pressing any key, Enter max cycles =
30000 is displayed. The maximum permitted number of rotor cycles specified on the hanger has to be entered
before the centrifugation run can be restarted (see chapter "After starting the first centrifugation run, enter the
maximum permitted number of rotor cycles or deactivate the cycle counter").
For rotors and hangers which are not labelled with the maximum permissible number of running cycles, the cycle
counter can be deactivated (see chapters "After starting the first centrifugation run, enter the maximum permitted
number of rotor cycles or deactivate the cycle counter" and "Activating or deactivating the cycle counter").
Each time the lid is opened, the number of rotor cycles (centrifugation runs) of the current rotor code is displayed,
e.g. CYCLES 5120 of 30000.
If the entered maximum permitted number of rotor cycles of a hanger is exceeded, the message  MAX CYCLES
PASSED  is displayed after every start of a centrifugation run and the centrifugation run has to be restarted.
If  MAX CYCLES PASSED  is displayed, the hanger has to be replaced with a new hanger for safety
reasons.
After replacing the hanger, the cycle counter has to be reset to "0" when the rotor is at rest (see chapter "Reset cycle
counter to "0" and enter maximum permitted number of rotor cycles").

 Enter max cycles = 30000 is displayed.
Use the knob to set the maximum permitted number of rotor cycles specified on the hanger.
For rotors and hangers which are not labelled with the maximum permissible number of running cycles, the cycle
counter can be deactivated. Turn the knob
