1.8.2.2 Rotor recognition
The centrifuge will recognize the inputted rotor through the set up in the control panel. As soon
as the lid get closed the rotor number will be indicated in the speed display.
If the pre-selected rpm is higher than the permitted rpm of the rotor, the rpm pre-selection
indication will flash when starting the centrifuge.
But the regulation will accelerate the rotor only to its permitted rpm.
Do not use a rotor, which isn't set to the control panel.
1.8.2.3 Speed signal
The actual speed is extracted by a hall-effect-sensor placed on the lower side of the motor.
There is a “preset/actual "comparison in the control board. Thereupon a new “actual-signal” is
given by the control board to the converter.

1.8.2.4 Lid mechanism
The micro switch in the mechanism of the lid lock controls the correct closing of the centrifuge
lid.
The switch may never be bypassed.
The lid lock is unlatched by an magnet, receiving its signal from the control board.
The actual state is indicated in the display (see M1, M2).
