Autoclaving

The rotor and accessories must not be autoclaved.
15.4

Centrifuge containers

•
With leakiness or after the breakage of centrifuging containers broken container parts and leaked centrifugation
material are to be completely removed.
•
The rubber inserts as well as the plastic sleeves of the rotors are to be replaced after a glass breakage.
Remaining glass splitters cause further glass breakage!
•
If this concerns infectious material, a disinfection process is to be executed immediately.

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 of fault
No voltage
Mains input fuses defective.
Failure of speed impulses during
operation.
Power failure during the centrifugation run.
(The centrifugation run was not finished.)
The rotor is unevenly loaded.
Fault in control unit or power unit.
Motor or motor control defective.
Supply voltage outside tolerance (see
Technical Data).
Fault in the power unit.
Excess temperature switch in motor has
triggered.
Fault in control unit.
Error in lid locking or lid closure.
Short circuit in control unit / power unit.
Incorrect machine version
Remedy
Check distribution voltage.
-
Check mains power input fuse,
-
refer to Chapter "Change mains
input fuse".
Mains switch ON.
-
Due to safety reasons the lid can
-
only be opened after approx. 120
seconds.
After this time has expired perform
-
a MAINS-RESET.
When stationary, open lid and
-
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.
-
Perform a MAINS RESET when
-
the rotor has been stationary.
Perform a MAINS RESET when
-
the rotor has been stationary.
Perform a MAINS RESET when
-
the rotor has been stationary.
Check supply voltage.
-
Perform a MAINS RESET when
-
the rotor has been stationary
When rotor is stationary, open lid
-
using emergency unlocking (see
Emergency Unlocking chapter).
Allow motor to cool down.
-
Perform a MAINS RESET when
-
the rotor has been stationary.
