5.7 Safety features
Cover lock
The centrifuge can be started only with properly closed cover. While, the cover can be opened only after stop-
ping 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.
Unbalance detecting
When loads of opposite buckets or carriers in rotors are unbalanced, the drive will be switched-off during accelera-
tion or operation of the centrifuge – and the error message will be displayed.
Rotor verification and checking compatibility with loaded 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 signaled 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. (Excepting emergency cover opening) – see p.
TROUBLESHOOTING.
Checking of excessive temperature
If temperature in rotation chamber exceeds 50°C (C0336) / 65°C (C0336R) 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.
5.8 Increase in temperature (C0336 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.
6 Centrifuging
Power switching ON/OFF is carried out with master switch situated on the side wall of the centrifuge. All settings
on the centrifuge are done by means of the control panel.
6.1 Control panel
The control panel placed on the front casing serves the purpose of controlling centrifuge operation.
