16 Centrifugation
When the centrifuge is running, according to EN / IEC 61010-2-020, no persons, dangerous substances or
objects may be within the safety margin of 300 mm around the centrifuge.
If the permissible weight difference within the rotor loading has been exceeded, the drive shuts down during
the start-up, the unbalance display lights up, and
IMBALANCE
is displayed.
A centrifugation run can be stopped at any time by pushing the key
STOP
.
All parameters can be selected and altered during the centrifugation run (see Chapter “Entering centrifugation
parameter”).
You can switch-over at any time between the RPM and RCF display with the key
RCF
. The input of the
centrifugation radius is necessary if you are working with the RCF display.
If
OPEN OEFFNEN
is displayed, a further operation of the centrifuge is only possible after opening the lid
once.
If
R xx n-max xxxxx
is displayed, then no centrifugation run has taken place as the rotor was changed
beforehand, refer to Chapter " Rotor Identification ".
Turn on the mains switch. Switch position
.
Load the rotor and close the centrifuge lid.
