Frontier Centrifuges

During the run you can call up the rotor type at any time by pressing the key "Door Open" (7).
3.2.2 Lid lock
The lid should only be put down slightly. An electromagnetic 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!
3.3 Preselection
3.3.1 Preselection of speed / RCF-value
This pre-selection is activated through the key "RPM | RCF" (4) (refer to figure 19 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 knob (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 the centrifugal force
at 200 rpm and the maximum permissible centrifugal force of the rotor.
See "Table 3: max. speed and RCF-values for permissible rotor" (See APPENDIX). All important values are
listed there.
