Setting parameters
The data setting and read-out system are part of a hermetically closed keyboard with distinctly
accessible operation points. Easily readable displays confirm the selected features and facilitate the
operator’s programming and recording of parameters and condition of the centrifuge.
The centrifuge is provided with the USB interface that enables connection of the centrifuge to an
external PC unit with the printer and recording of the centrifugation parameters.
Safety features
Lid lock
The centrifuge can only be started when the lid is properly closed. Similarly, the lid can only be
opened once the rotor has stopped. In case of emergency opening of the lid during operation, the
centrifuge will be immediately switched-off and the rotor will slow to a complete stop.
Unbalance detecting
Should loads of opposite buckets or carriers in rotors be unbalanced, the drive will be switched-off
during acceleration or operation of the centrifuge and an error message will be displayed.
Rotor verification and checking compatibility with loaded programme
Upon starting centrifuging, the unit verifies the type of the rotor installed and in the case of its
incompatibility with the type indicated in the application or absence of the rotor, the spinning process will
stop with simultaneous displaying of an error message. The conformity of the type of the rotor is signalled
with a single audible signal. If the auto-identification (see 9.8 Other) option is checked, the proper rotor will
be automatically chosen, without the user input.
Rest state inspection
Opening of the centrifuge’s cover by pressing the
COVER
button is possible, but only when the
rotor is in a state of rest. Use the inspection glass to ensure the rotor is in the rest state. When the rotor is
being stopped, the brake symbol (see 6.2) is visible and goes off when it stops. The opening of the
emergency cover during rotor running is prohibited.
Checking of excessive temperature
If the temperature in rotation chamber exceeds 50°C (Harrier) / 65°C (Harrier R/RH) caused by, for
example, a malfunction of the cooling system, the drive will be switched off and an error message will be
displayed. The reboot is only possible after the device has cooled down.
Increase in temperature (Harrier only)
In uncooled centrifuges, the temperature in the rotor chamber, rotor and sample can increase to
above 40°C, based on the run time, g-force (rcf)/speed and ambient temperature.
