7 Malfunctions and Error Correction
7.1 General Malfunctions
Malfunctions are indicated by error messages with a number in the
speed display.
In the event of a fatal error (e.g. a defective lid lock), a certain safety
time will be counted down on the display. During this time, “ERR” and
“SAFE” flash alternately on the display. When the time is up, "OFF"
will be displayed.
Do not switch the centrifuge off until “OFF” is displayed.
This is necessary in order to ensure that the rotor is at a complete
standstill.
• Eliminate the source of the problem (see tables in fig. 7.1 and 7.3).
• Acknowledge the error messages with the lid key.
