Calling up program linkage


button repeatedly until the parameter RCL A...Z is displayed.
Press the
PROG

Use the adjusting knob

Press the key. Briefly, Multi program recall ... is displayed as confirmation.
START
The centrifugation data of the first program of the program linkage as well as the total runtime of the program
linkage are displayed.
19.5

Automatic temporary storage

The program place 0 serves as temporary storage for centrifugation data of the last centrifugation run that took place.
No programs can be saved at this program place.
After every start to a centrifugation run, the centrifugation data that is used for the run is automatically saved at
program place "0" and can be accessed there.

Centrifugation

When the centrifuge is running, according to EN / IEC 61010-2-020, no persons, dangerous substances or
objects may be within the safety margin of 300 mm around the centrifuge.
For centrifuges with the heating / cooling option, after a centrifugation run with a very high temperature (e.g.
+90°C), it is necessary to wait until the cover of the centrifuge has cooled down to ambient temperature before
carrying out a centrifugation run with cooling. Failure to comply with this rule may result in cracks in the cover.
If a program lock has been set, its function has to be observed. The functions of the various program locks are
described in the chapter "Setting program locks".
If Enter max cycles = 30000 is displayed, first of all the maximum permitted number of rotor cycles specified
on the hanger is entered, before the centrifugation run can be restarted (see chapter "Cycle Counter").
If the permitted difference in weight of the rotor load is exceeded, the centrifugation run is canceled during the
start-up and IMBALANCE is displayed.
If the speed in the selected program is higher than the maximum speed of the rotor (Nmax), it will not be
possible to start a centrifugation run. The message N > ROTOR MAX will be displayed (see Chapter "Faults").
If a start-up time is set which is longer than the running time, no centrifuge run can be started.Acc time > Run
time is displayed (see Chapter "Faults").
If N > ROTOR MAX in Prog : e.g. 5, Runtime 00:00 in Prog : e.g. 5, Empty Program or Ramp Unit Time
in Prog : e.g. 3 is displayed during program linkages, no centrifuge run can be started (see Chapter "Faults").
A centrifugation run can be stopped at any time by pushing the key
During a centrifugation run, parameters can be selected and modified (see chapter, "Change settings during
centrifugation run").
It is possible to switch over between RPM and RCF display at any time using the
Switching is not possible if program linkages are being used. When working with the RCF display, it is
necessary to enter the centrifuging radius.
If OPEN OEFFNEN is displayed, a further operation of the centrifuge is only possible after opening the lid
once.
If the rotor has been changed, no centrifugation run takes place and this display is shown, e.g.
Rotor 4 Nmax= 4500 R=184 mm (see chapter "Rotor Identification").
Operation errors and malfunctions will be shown (see Chapter "Faults").
 Switch on the mains supply switch. Switch position .

Load the rotor and close the centrifuge lid.
