7.1 General malfunctions
Malfunctions are indicated by error messages with a number in the
speed/RCF 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.
WARNING
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 below).
• Acknowledge the error messages with the lid key.
