Lid lock

The lid should only be put down slightly. An lid lock closes the lid, at the same time the word "open" (M2) disappears
(refer to figure 15).
As a sign that the centrifuge is ready for starting, in the display "RPM | RCF" (A-1) the word "close" (M1) appears.
Simultaneously the word "rotor" (M3) is displayed, as well as the code number of the rotor, which is in the centrifuge
system, "no 71" (M4). With that, all rotor specific data, like e. g. max. speed, acceleration etc., are adopted.
ATTENTION:
Don't grip your fingers between lid and device or locking mechanism when closing the lid!
Before closing the lid, please check if the rotor is tightened.

Preselection

3.3.1

Preselection of speed / RCF-value

This pre-selection is activated through the key "RPM/RCF" (5) (refer to figure 16 below). By pressing the key once
the word "rpm" (M5) flashes. By pressing the key twice the pre-selection of the centrifugal forces can be selected.
Then the flashing word "rcf" (M6) appears. You can set the desired values with the adjusting dial (1). In the display
(A-1) the regulated value is shown permanently, before, during and after the run.
As long as no rotor is inserted, the speed is adjustable between 200 rpm and maximum revolution of the centrifuge.
If there is a rotor in the centrifuge the speed can only be pre-selected until the maximum permissible revolution of
that rotor. It is the same with the pre-selection of the RCF-value. The setting range is between 20 x g and the
maximum permissible centrifugal force of the rotor.
See "Table 4: max. speed and RCF-values for permissible rotor" (See APPENDIX). All important values are
listed there.
ATTENTION:
Please also check the maximum permissible revolutions of your test tubes with the manufacturer.
3.3.2

Preselection of running time

The running time can be pre-selected in three different ranges from 10 seconds up to 99 hours 59 minutes.
1. Range from 10 seconds up to 59 minutes 50 seconds in steps of 10 seconds
2. Range from 1 hour up to 99 hours 59 minutes in steps of 1 minutes
3. The continuous run "cont", which can be interrupted by the key "Stop/Lid"(9) (refer to figure 17).
The running time can be pre-selected with the lid open or closed.
To activate the setting of the running time press the key "Time" (7).
In the display "Time/Prog" (A-4) flashes the indication "m : s" or "h : m", depending on the previous setting.
To set the desired value, use the adjusting dial (4). After exceeding 59 min 50 sec the indication changes
automatically into "h : m". After exceeding 99 hours 59 min the word "cont" appears in the display "Time/Prog"
(A-4). That continuous run can only be interrupted by pressing the key "Stop/Lid" (9). The time countdown starts as
soon as the set speed is reached.
The display always shows the remaining running time. (See figure 17)
