Control and display elements

See figure on page 2.
Fig. 2, Fig. 3: Display and control panel
13.1

Control knob

For setting the individual parameters.
Turning anticlockwise reduces the value. Turning clockwise increases the value.
13.2

Control panel pushbuttons (keys)

•
Selection control key for selection of specific parameter.
SELECT
The subsequent parameter is selected by every further keystroke.
•
Start centrifugation run. The LED in the button lights up during the centrifugation run as long as the
START
rotor is turning.
IMPULS
•
Short-term centrifugation.
The centrifugation run is effected as long as the button is held down. The LED in the button lights up
during the centrifugation run as long as the rotor is turning.
•
Store inputs and changes.
•
End centrifugation run.
STOP
The rotor runs down with a pre-selected brake step. The right-hand LED in the button lights up until the
OPEN
rotor is stationary. Once the rotor is stationary the left-hand LED flashes in the button. Pressing the
button twice triggers the EMERGENCY STOP.
•
Unlock the lid.
The left-hand LED in the button goes out.
•
Leave the parameter input.
•
Switch between RPM and RCF display.
RCF
RCF values are displayed in > <.
•
Start pre-cooling.
The pre-cooling speed is settable. It is pre-adjusted to 10000 RPM.

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 force. 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.
