8.11 Unbalance

The centrifuge is provided with the rotor unbalance sensor and when it will be activated, centrifugation process
will be stopped through fast braking and at the same time an error message will be displayed. Cancellation of
this error is possible only through pressing BACK key after stopping of the rotor.
One must check if rotor was correctly loaded, close the cover and once more start the program. In order to protect
the rotor against beating in opposite areas of the rotor, it has to be provided with identically filled buckets, carriers,
test-tubes etc. for getting the best balance possible (see section 4.3).
Then close the cover and restart the program.
Unbalance causes noise and vibrations during operation, and adversely affects power transmission
system (motor, shock absorbers). The better balance, the smoother will be the centrifuge operation
and therefore longer life of usage of the driveline. Moreover, the ideal separation level is then obtained,
as already separated constituents would not be moved up by vibration.
Emergency stop
In any moment of centrifuging it is possible interrupt the process and fast stop the rotor. Single-time pressing
of the STOP key will make centrifuging stop with acceleration characteristics set in the program (after pressing
the SET or STOP key, the device returns to the main screen). Pressing and holding it up to 1s will make the
centrifuging quick stop.
