If the fault cannot be eliminated with the help of the fault table, please inform Customer Service.
Please state the type of centrifuge and the factory serial number. Both values are visible on the centrifuge type plate.
Perform a MAINS RESET:
− Switch off the mains switch (switch position "0").
− Wait at least 10 seconds and then switch on the mains switch again (switch position " Ι ").

press key.
START
Repeat the centrifugation run if
-
necessary.
Open lid when rotor is stationary.
-
Check the loading of the rotor, see
-
chapter "Loading the rotor".
Repeat the centrifugation run.
