35/102
Rotation indicator. The indication appears while the centrifuge is running as long as the rotor is turning.
STOP
Centrifugation run stopped or finished. Indication after completion of the centrifugation run as long as the
rotor is turning. The indicator flashes following an emergency stop.
LOCK 1,
LOCK 2
Keyswitch position (for centrifuges with keyswitch only).
LOCK 4,
LOCK 5
Program interlocking when serial communication provided (for centrifuges with serial communication only).
PC,
PC
Serial communication (for centrifuges with serial communication only).
Operating errors or faults that occur are shown symbolically in the display (see Chapter "Faults").
12.2 Control
knob
For setting the individual parameters.
Turning anticlockwise reduces the value. Turning clockwise increases the value.
12.3 Keys and set-up options
t
Running time, parameter t/min:sec
1. Parameter t/min: Adjustable from 1 - 999 min, in 1 min steps.
2. Parameter t/ :sec Adjustable from 1 - 59 s, in 1 second steps.
3. Continuous
running "---:--"
RCF
Interrogation of the integral RCF, parameter
∫
RCF.
n
1. Speed, parameter RPM
A numerical value from 50 RPM up to the maximum speed of the rotor (n-max-Rotor) can be set. Maximum
speed of the rotor, see Chapter "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories".
Adjustable in steps of 10.
2. Interrogation of the maximum speed of the rotor, parameter n-max-Rotor.
RCF
1. Relative centrifugal force, parameter RCF/RZB
A numerical value can be set, which gives a speed between 50 RPM and the maximum speed of the rotor
(n-max-Rotor). Adjustable in steps of 1.
2. Interrogation of the maximum RCF of the rotor, parameter RCF-max-Rotor.
Run-up parameters
1. Run-up steps, parameter
1-9
. Step 9 = shortest run-up time, ... Step 1 = longest run-up time.
2. Run-up time, parameter
min:sec
t
. The time range that can be set is dependent upon the set speed.
Run-down parameters
1. Braking steps, parameter
0-9
. R = linear braking curve, B = similar to an exponential braking curve.
Step R9, B9 = short run-down time, ... Step R1, B1 = long run-down time, Step R0 = unbraked run-down.
2. Run-down time, parameter
min:sec
t
. The time range that can be set is dependent upon the set speed.
3. Brake de-energisation speed, parameter n
(•)
/RPM
After reaching this speed, unbraked run-down occurs.
1. Temperature setpoint, parameter T/°C (for centrifuges with cooling only). Adjustable from -20°C to +40°C,
in 1°C steps (heating/cooling option settable between -20°C and +60°C / +90°C). The lowest temperature
that can be achieved is dependent upon the rotor (see Chapter "Anhang/Appendix, Rotoren und
Zubehör/Rotors and accessories").
2. Centrifuging radius, parameter r/mm. Entry in mm. Centrifuging radius, see Chapter "Anhang/Appendix,
Rotoren und Zubehör/Rotors and accessories“.
START
1. Start centrifugation run. The rotation indicator appears.
2. Acceptance of changes during the centrifugation run.
STOP
Stop centrifugation run.
The rotor decelerates with the preset run-down parameters. Pressing the key twice will initiate an emergency
stop.
PROG
Select program location, parameter PROG-Nr.
RCL
Calling up of programs.
STO
Saving of programs.
89 programs can be saved (program locations 1 to 89). Note: The program locations "
----
" and 90 to 99 are
used as automatic buffers (see Chapter "Automatic buffer"). No programs can be saved in these program
locations.
