27 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 "").
Message / fault
Cause
Remedy
No display
---
No voltage.
Overvoltage protection tripped out.
− Check supply voltage.
− Mains switch ON.
TACHO - ERROR
1, 2, 96
Faulty speedometer.
Motor, electronics defective.
− 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 ""). The rotor must

CONTROL - ERROR
8
Error in lid locking or lid closure.
IMBALANCE
---
The rotor is unevenly loaded.
− Open lid.
− Check the loading of the rotor, see
chapter "Loading the rotor".
− Repeat the centrifugation run.
CONTROL - ERROR
4, 6
Error in lid locking or lid closure.
− Perform a MAINS RESET.
N > MAX
5
Rotation too fast
N < MIN
13
Rotation too slow
MAINS INTERRUPT
---
Power failure during the centrifugation run.
(The centrifugation run was not finished.)
− Open lid.
− Push
START / IMPULS
button.
− Repeat the centrifugation run if
necessary.

KEYBOARD-ERROR
---
Error / defect controls
NO ROTOR
---
No rotor installed
− Open lid.
− Install rotor.
N  ROTOR MAX
---
Speed in the selected program greater than
the maximum speed of the rotor.
− Check the set speed.
Reduce the set speed
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.
− 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".
