Displaying the maximum RCF of the rotor


Press the key repeatedly until the parameter RCF/RZB is displayed and the input field is shown inversely.
RCF

Press the key once more and hold it pressed; the maximum RCF of the rotor (RCF-max-Rotor) will be
RCF
displayed.
24

Emergency stop


Press the key twice. The STOP symbol will flash in the display.
STOP
In the case of an emergency stop, run-down takes place with braking step R9 (shortest run-down time). If braking
step R0 was selected, the run-down time will be longer than with braking step R9 for technical reasons.

Audible signal

The audible signal sounds in accordance with the following philosophy:

OFF
at 2 s intervals on the occurrence of a fault

ON1
at 2 s intervals on the occurrence of a fault

at 30 s intervals on completion of a centrifugation run and the rotor coming to rest.
ON2 
at 2 s intervals on the occurrence of a fault

at 30 s intervals on completion of a centrifugation run and the rotor coming to rest.

every time a key is pressed
The audible signal is silenced by opening the lid or pressing any key.
The signal can be set as follows when the rotor is at standstill.

Open the lid.
