Version 12/2008, Rev. 1.11 of 27/01/2012
Translation of the original operating manual
Cut:
The curve speed in an interval will automatically be
limited to the set speed in the operating mode.
Admit:
The curve speed in an interval will be allowed.
Cancel:
A stop occurs. Starting is impossible without a change
of the curve speed in an interval.
Modification of existing curves
Activate the field “CURVES” in the configuration menu.
Select the curve that is to be modified and change the individual
values as described above.
Centrifugation curves
It is also possible to create centrifugation curves. The following
conditions must be fulfilled:
The preselected maximum final speed of an interval corresponds
to the set speed for the centrifugation run.
The sum of the intervals corresponds to the set time of the centri-
fugation run. The last speed checkpoint of an interval equals 0.
6.3.3.9 Modification of the Contrast
Press the stop key and turn the function knob one notch to the
left. A dialog box will be displayed.
Modify the contrast of the centrifuge display and confirm the
modification.

6.3.3.10 Imbalance Monitoring
An imbalance dialog box will be displayed in the event of an
inadmissible imbalance. The centrifugation run cannot be continued
and the centrifuge will be stopped with maximum deceleration power.
Fig. 6.23: Imbalance dialog box
Reason: Improper loading of the centrifuge or a malfunction during
the operation (e.g. glass breakage) that in turn prevented the
centrifuge from rotating steadily.
Eliminate the cause of the imbalance (see chapter 7
"Malfunctions and Error Correction") and restart the centrifuge.
