4.1.6 Glass breakage

With high g-values, the rate of glass tube breakage increases. Glass splinters have to be removed
immediately from rotor, buckets, adapters and the rotor chamber itself. Fine glass splinters will scratch
and therefore damage the protective surface coating of a rotor. If glass splinters remain in the rotor
chamber, fine metal dust will build up due to air circulation. This very fine, black metal dust will
significantly pollute the rotor chamber, the rotor, the buckets and the samples.
If necessary, replace the adapters, tubes and accessories to avoid further damage. Check the rotor
bores regularly for residues and damage.
ATTENTION:
Please check the relevant specifications of the tubes centrifuges with the
manufacturer.
4.1.7 Life time of rotors, buckets, accessories
Rotors and rotor lid made of aluminum or stainless steel, have an operating time of max. 7 years from
first use. Transparent rotor lids and caps made of PC or PP as well as rotors, tube racks and adapters of
PP have a maximum operating time up to 3 years from first use.
Condition for the operating time: Proper use damage-free condition, recommended care.

5.1 Error message: Cause / Solution
The error messages are listed to help localize possible errors faster.
The diagnosing referred to in this chapter may not always be the case, as they are only theoretically
occurring errors and solutions.
Please keep us informed about any kind of error occurring, which is not listed in this chapter. Only
through your information are we able to improve this operation manual.
Many thanks in advance for your support.

5.2 Survey of possible error messages and their solutions

5.2.1 Lid release during power failure (Emergency Lid Release)

The OPEN button suddenly fails due to shutdown as a result of power failure or due to shutdown as a
result of the burnout of fuse of the instrument. In order to protect the centrifuge sample, a pull ring is set
at the bottom of the instrument. Please pull the pull ring downward, the door lock will be opened, and the
door cover can be pushed open. However, the following rule-breaking operations are strictly prohibited.
(1) In the case the revolutions per minute of the instrument is not reduced to 100r/min during speed
reduction and shutdown, it is strictly prohibited to pull the pull ring at the bottom of the instrument to forcibly
open the door lock and manually force the rotor to stop operation, as which will cause personal injury.
(2) It is strictly prohibited to manually turn off the power switch and then turn on the power to press the
OPEN button to open the lid and force the rotor to stop by hand at the point when the program of the
instrument considers that the revolutions per minute is 0.

5.2.2 Description of the error message system

When operates the instrument improperly or a failure occurs, an error code will appear in the "Time"
window. See the following table for information about error codes.
