Centrifuging
Once the rotor has been properly installed, the main switch has been
turned on and the lid has been closed, you can start centrifuging.
Starting centrifuge program
Press the START key on the control panel. The centrifuge accelerates
to the pre-set speed with the time display active.
If the speed setting is higher than the maximum permissible speed or
RCF-value for the particular rotor, then the display will show the
message max. 4,700 rpm once the centrifuge has been started.
Within 15 seconds you can apply this value by pressing the "START"
key
again, and the centrifuging program will continue. Otherwise
the centrifuge will stop and you will have to enter a valid number.
You cannot open the lid as long as the centrifuge is running.
Imbalance indicator If a load is imbalanced, this will be indicated at speed higher than
approx. 300 rpm by the message "Imbalanced load".
The run will terminate.
Check the loading and start the centrifuge once again. See the
information on proper loading in the rotor instruction manual. For
information on troubleshooting, see section
“Troubleshooting by user”
on page 7-4 .
Stopping the centrifuging
program
With preset running time
Usually the running time is preset and you only have to wait until the
centrifuge stops automatically when the preset time limit expires.
As soon as the speed drops to zero, the message "END" will appear in
the display. By pressing the OPEN key
, you can open the lid and
remove the centrifuged material.
You can also stop the centrifuging program manually at any time by
pressing the
"Stop" key.
Continuous operation
If you selected continuous operation (see “Continuous operation” on
page 4-8 ), you will have to stop the centrifuge manually. Press the STOP
key on the control panel. The centrifuge will be decelerated at the
designated rate. The message "END" will illuminate, and after pressing
the OPEN key
, the lid will open and you can remove the centrifuged
material.
