13 Entering centrifugation parameter
If no key is pressed for 8 seconds long after the selection or during the input of parameters, the previous
values will be shown in the display. The input of parameter then has to be executed again.
• Select the RPM or RCF display with the key
RCF
. If the RCF display is selected, the LED in the key
RCF
.
lights up.
• Select the desired parameter with the key
, and adjust with the keys .
In order to set continuous operation, the parameters t/min and t/sec must be set to zero with the key.
Continual running is represented in the display by the following symbol, "∞".
• After input of all parameters, press the key
START
in order to store the adjustments on the programme position #.
As confirmation, ∗∗∗ ok ∗∗∗ will be displayed for a short period.
The data on the programme position # will be overwritten with every input of parameters and pressing of the
key
START
.
14 Programming
14.1 Programme input/alteration
• Select the RPM or RCF display with the key
RCF
. If the RCF display is selected, the LED in the key
RCF
.
lights up.
• Select the desired parameter with the key
, and adjust with the keys .
• Select the parameter PROG with the key
, and set the desired programme position with the keys . The
LED in the key
PROG
lights up.
• Press the key
PROG
in order to store the adjustments to the desired programme position. As confirmation, ∗∗∗
ok ∗∗∗ will be displayed for a short period.
14.2 Programme recall
• Select the desired programme position by pressing the key
PROG
.
The centrifugation data of the selected programme position will be displayed.
• The parameters can be checked by pressing the key
.
15 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.
If the speed in the selected program is higher than the maximum speed of the rotor, it will not be possible to
start a centrifugation run. N > ROTOR MAX will be displayed (see Chapter "Faults ").
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 Ι.
• Load the rotor and close the centrifuge lid.
