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.
17 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.
17.1 Running
time
17.1.1 Time
selection
x
Press the
t
key repeatedly until the parameter t/min: or t/ :sec is displayed. The input field will be displayed
inversely.
x
Set the desired value by means of the control knob .
17.1.2 Continuous
running
x
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 . "---:--" will be displayed in the input field.
17.2 Speed
(RPM)
x
Press the
n
key repeatedly until the parameter RPM is displayed and the input field is shown inversely.
x
Set the desired value by means of the control knob .
17.3
Relative centrifugal force (RCF/RZB)
x
Press the
RCF
key repeatedly until the parameter RCF/RZB is displayed and the input field is shown inversely.
x
Set the desired value by means of the control knob .
The centrifuging radius indicator will flash while the adjustment is being made.
17.4
Run-up and run-down parameters
The run-up and run-down parameters that have been set are displayed.
x: 1-9 = run-up step, t = run-up time
x
y
PROFIL
y: R1-R9, B1-B9 = braking step, R0 = unbraked run-down, t = run-down time, n
(•)
= brake de-
energisation speed
17.4.1 Run-up
step
x
Press the
key repeatedly until the parameter
1-9
or
t
is displayed. The input field will be displayed
inversely.
x
Set the desired step by means of the control knob .
17.4.2 Run-up
time
x
Press the
key repeatedly until the parameter
min:sec
t
is displayed. The input field will be displayed inversely.
x
Set the desired value by means of the control knob .
If a run-up time is set that is longer than the running time, the centrifugation run will end before the set speed is
reached.
