12.3 Adjustment possibilities
PROG RCL Program position of the called-up program.
t/min
Running time. Settable from 0 - 99 min, in 1 min increments.
t/sec
Running time. Settable from 0 - 59 s, in 1 second increments.
Continuous run (
∞
). Set parameter
t/min
and
t/sec
to zero.
RPM
Revolutions per minute. A numerical value from 500 RPM up to the maximum speed of the rotor can be
set. Maximum speed of the rotor, see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and
accessories". Settable in increments of 10.
RAD/mm
Centrifugation radius. Input in mm. For centrifugation radius see Chapter "Anhang/Appendix, Rotoren
und Zubehör/Rotors and accessories". The input of the radius is only possible if the RCF display
(> RCF <) is selected.
RCF
Relative Centrifugal Acceleration. A numerical value can be set, which gives a speed between 500 RPM
and the maximum speed of the rotor. Adjustable up to 100 in intervals of 1, and from 100 in intervals of
10. The RCF value is automatically rounded up or rounded down with regard to the RPM interval. The
input of the RCF is only possible if the RCF display (> RCF <) is selected.
Starting steps 1 - 9. Step 9 = shortest starting time, Step 1 = longest starting time.
Brake steps 1 - 9. Step 9 = shortest run-down time, Step 1 = longest run-down time.
T/°C
Temperature Set Point (only in centrifuges with cooling). Adjustable from -10°C to +40°C, in 1°C
intervals. The lowest obtainable temperature depends on the rotor (see Chapter "Anhang/Appendix,
Rotoren und Zubehör/Rotors and accessories").
PROG STO Program position on which the program is stored. 4 programs can be stored (program positions 1 - 2 – 3
- 4).
13 Programming
13.1 Programme
input/alteration
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
. RCF values are displayed in
> <
.
•
Select the desired parameters using the button
SELECT
and set using the knob .
If continuous run is desired the parameters t/min and t/sec need to be set to zero on the knob and the symbol
∞
is displayed.
•
The parameter
PROG STO
can be selected using the button
SELECT
and the desired program position set using
the knob .
•
Press the button
START / IMPULS
in order to store the setting on the desired program position.
∗∗∗

is
displayed briefly as confirmation.
The previous data in the program position is overwritten during saving.
13.2 Programme
recall
•
Select the parameter
PROG RCL
using the button
SELECT
and set the desired program position using the knob
.
•
Press the button
START / IMPULS
. The centrifugation data of the selected program position is displayed.
•
The parameters can be checked by pressing the button
SELECT
.
To leave the parameter display press the button
STOP / OPEN
or press no button for a period of 8 seconds.
14 Centrifugation
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 / OPEN
.
All parameters can be selected and altered during the centrifugation run (see Chapter “Programming”).
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.
•
Turn on the mains switch. Switch position
Ι
.
•
Load the rotor and close the centrifuge lid.
