Status symbols

Lid open.
Lid closed.
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, Keyswitch position.
LOCK 2
LOCK 4,
Program interlocking when serial communication provided (for centrifuges with serial communication only).
LOCK 5
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").
17.2

Control knob

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

Keys and set-up options

Running time, parameter t/min:sec
t
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 "---:--"
Interrogation of the integral RCF, parameter ∫RCF.
RCF
1. Speed, parameter RPM
n
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.
1. Relative centrifugal force, parameter RCF/RZB
RCF
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
2. Run-up time, parameter
Run-down parameters
1. Braking steps, parameter
Step R9, B9 = short run-down time, ... Step R1, B1 = long run-down time, Step R0 = unbraked run-down.
2. Run-down time, parameter
3. Brake de-energisation speed, parameter n
After reaching this speed, unbraked run-down occurs.
1. Temperature setpoint, parameter T/°C. Adjustable from -20°C to +40°C, in 1°C steps (heating/cooling
option settable between -20°C and +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".
62/165
. Step 9 = shortest run-up time, ... Step 1 = longest run-up time.
