System check
An internal system check monitors the data transfer and sensor signals with
regard to plausibility. The system continuously performs a self-check and
identifies malfunctions. Malfunctions are indicated by error messages with a
number in the speed/rcf display (see chapter 7.2 - "Table of error codes").

Remaining hazards
The centrifuge was built in accordance with the state of the art and in
compliance with the generally recognized safety rules. However, danger to
life and limb of the operator, or of third parties, or impairments of the unit or
other material assets cannot be completely excluded when the unit is being
used.
• Use the unit only for the purpose that it was originally intended for (see
chapter 1.2 - "Intended use").
• Use the unit only if it is in a perfect running state.
• Immediately eliminate any problems that can affect safety.
