Control Device; Setting Parameters; Safety Features - Labnet C0226R User Manual

In order to prolong lifetime of the rotor and gaskets rotors shall be lubricated with the
maintenance oil, while gaskets and threaded parts shall be lubricated with the petroleum jelly.
For replacement of the rotor one shall unscrew clamping and then grab the rotor with both hands
at opposite sides, taking it away from drive shaft by pulling it up.

Control device

The microprocessor control unit of the centrifuge ensures broad possibilities of providing,
realisation and reading of work parameters.

Setting parameters

Data setting and read-out system forms hermetically closed keyboard with distinctly accessible
operation points. Easily readable displays signaling individual performed operations facilitate
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 external
PC unit with the printer and recording the centrifugation parameters.

Safety features

Cover lock
The centrifuge can be started only with properly closed cover, while the cover can be opened
only after stopping the rotor. In case of emergency opening of the cover during operation, the
centrifuge will be immediately switched-off and the rotor will brake till complete stopping. During
cover closing it is prohibited to press any buttons. Do not place fingers into closing area during cover
closing.
Unbalance detecting
When loads of opposite buckets or carriers in rotors are unbalanced, the drive will be switched-
off during acceleration or operation of the centrifuge – and the error message will be displayed.
Rotor verification and checking compatibility with set program
Directly after starting centrifuging, a unit verifies the type of the rotor applied and in the case
of its incompatibility with the type indicated in the application or absence of the rotor, the spinning
process shall be stopped with simultaneous displaying the error message. The conformity of the type
of the rotor is signalled with a single audible signal. In case auto identification (see 9.8 Other) option is
checked, proper rotor will be automatically chosen, without user engagement.
Rest state inspection
Opening of the centrifuge's cover is possible only with the rotor in the state of rest. When the
rotor is being stopped, the STOP diode is on and goes off when it is stopped. (except emergency cover
opening) – see p. TROUBLESHOOTING.
Checking of excessive temperature
If temperature in rotation chamber exceeds 50°C caused by, for example, malfunction of
cooling system, drive will be switched off and error message will be displayed. The reboot is only
possible after chilling device.
