Operating errors or any occurring disturbances are symbolised in the display (see Chapter "Faults").
13.2 Control panel pushbuttons (keys)
Selection control key for selection of specific parameter.
The subsequent parameter is selected by every further keystroke.
By pushing the arrow keys the value of a previously selected parameter is increased or decreased. By
keeping an arrow key depressed the value is increased or decreased with increasing speed.
START
Start the centrifugation run. The rotation display lights up.
Acquisition of input and changes.
STOP
Stop the centrifugation run.
The rotor runs down with pre-selected brake step. The LED in the key lights up until the rotor stops.
Pushing the key twice triggers the EMERGENCY STOP.
RCF
Selecting the RCF display.
The LED in the key lights up.
IMPULS
Short-term centrifugation.
The centrifugation run is effected as long as the key is held down.
PROG
Storing and recalling programmes.
The subsequent programme is displayed by every further keystroke (1 - 2 - 3 - #).
13.3 Adjustment possibilities
t/min
Adjustable from 1 - 99 min. in 1-min. intervals.
t/sec
Adjustable from 1 - 59 sec. in 1-sec. intervals.
Continuous run "
f
".
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". Adjustable from 500 RPM to 10000 RPM in steps of 10 and from 10000 RPM up to the
maximum speed in steps of 100.
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 is selected
(LED in the key
RCF
lights up).
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 is selected (LED in the key
RCF
lights up).
Starting steps 1 - 9. Step 9 = shortest starting time, Step 1 = longest starting time.
Brake steps 0 - 9. Step 9 = shortest run-down time, Step 1 = long run-down time,
Step 0 = longest run-down time (brakeless run-down).
T/°C
Temperature Set Point (only in centrifuges with cooling). Adjustable from -20°C to +40°C, in 1°C intervals
(heating/cooling option settable between -20°C and +60°C / +90°C). The lowest obtainable temperature
depends on the rotor (see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories").
PROG
Programme Number. 3 programmes can be stored (programme positions 1 - 2 - 3). The programme
position # serves as temporary storage for altered adjustments.
