Entering Centrifugation Parameters; Running Time; Time Selection; Continuous Running - Hettich ROTO SILENTA 630 RS Bedienungsanleitung

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".
1. Start centrifugation run. The rotation indicator
START
2. Acceptance of changes during the centrifugation run.
Stop centrifugation run.
STOP
The rotor decelerates with the preset run-down parameters. Pressing the key twice will initiate an emergency
stop.
Select program location, parameter PROG-Nr.
PROG
Calling up of programs.
RCL
Saving of programs.
STO
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.

Entering centrifugation parameters

It is only possible to enter a parameter when the input field is displayed inversely (dark background). An
inverse input field will go off automatically after 10 seconds.
14.1

Running time

14.1.1

Time selection


Press the key repeatedly until the parameter t/min: or t/ :sec is displayed. The input field will be displayed
t
inversely.

Set the desired value by means of the control knob
14.1.2

Continuous running


Select the parameters t/min: and t/ :sec one after the other (see Chapter "Time selection"), and set both to zero
using the control knob
14.2

Speed (RPM)


Press the n key repeatedly until the parameter RPM is displayed and the input field is shown inversely.

Set the desired value by means of the control knob
14.3

Relative centrifugal force (RCF/RZB)


Press the key repeatedly until the parameter RCF/RZB is displayed and the input field is shown inversely.
RCF

Set the desired value by means of the control knob
The centrifuging radius indicator will flash while the adjustment is being made.
