2.2.2 Lid Lock

The lid must only be closed slightly. An electromagnetic lid lock closes the lid, the word "open" (M2)

will no longer be displayed.

As a sign that the centrifuge is ready for starting, appearing in the display, "rpm/rcf"(A-1), the word

"close" (M1). Simultaneously, the word "rotor" (M3) appears, as well as the code number of the

rotor, which is in the centrifuge, i. e. " 221.40" (M4), along with all rotor specific data, for example:

max. speed, acceleration etc., are available.

For all number marked text, please refer to Figure16.

ATTENTION: Don't grip your fingers between the lid and the device or the locking

Selecting the key, "rpm/rcf" (4), pre-selection is activated. By pressing the key once, the word "rpm"

The flashing word, "rcf" (M6), will appear. The desired values can be selected, with the adjustable

knob (1). In the display (A-1), the regulated value is shown permanently: before, during and after the

run.
