Determination of the acceleration and braking times (for factory checks)
START Program 11
– completely equip the rotor
(the measured rotational speed is calculated by the program after the rotor recognition = 97 % of
the max. rotational speed of the rotor in use)
– close the lid
START run
Display of the acceleration time in seconds (at 97 % of the rotational speed nominal value)
STOP – start of the measurement of the braking time
Display braking time
STOP – return to the program selection
Overspeed cut-off test (Test with Rotor)
START Program 12
– Close the lid
– The software sets a rotational speed above the switching-off limit. If the device operates correctly, it
switches itself off when reaching the switching-off rotational speed and stops without braking.
If the device is not switched off, the run must be stopped immediately by hand!
– The device must be switched off!
On switching on again the centrifuge brakes and is then again in the normal operational mode.
Overspeed cut-off:
The overspeed cut-off is about 300 1/min above the nominal speed of the rotor in use.
