Faults

If the fault cannot be eliminated with the help of the fault table, please inform Customer Service.
Please specify the type of centrifuge and the serial number. Both numbers can be found on the name plate of the
centrifuge.
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 ").

Cause
--- No voltage.
Overvoltage protection tripped out.
Faulty speedometer.
Motor, electronics defective.
8 Error in lid locking or lid closure.
--- The rotor is unevenly loaded.
4, 6 Error in lid locking or lid closure.
5 Rotation too fast
13 Rotation too slow
--- Power failure during the centrifugation run.
(The centrifugation run was not finished.)
Incorrect rotor coding

--- Error / defect controls
--- No rotor installed
--- Speed in the selected program greater than
the maximum speed of the rotor.
The rotor has been changed. The maximum
speed of the installed rotor is higher than that
of the rotor that was previously used and this
has not yet been detected by rotor
recognition.

Remedy
−
Check supply voltage.
−
Mains switch ON.
−
Open the cover.
−
Switch off the mains switch (switch
position "0").
−
Wait at least 10 seconds.
−
Turn the rotor vigorously by hand.
−
Switch on the mains switch again
(switch position " Ι "). The rotor must
turn during switch-on.
−
Open lid.
−
Check the loading of the rotor, see
chapter "Loading the rotor".
−
Repeat the centrifugation run.
−
Perform a MAINS RESET.
−
Open lid.
−
Push START / IMPULS button.
−
Repeat the centrifugation run if
necessary.
−
Open lid.
−
Perform a MAINS RESET.
−
Open lid.
−
Install rotor.
−
Check the set speed.
Reduce the set speed
−
Set a speed up to the maximum
speed of the rotor that was
previously used. Press the
START / IMPULS key to run rotor
recognition. See chapter, "Rotor
Recognition".
