Safety of rotors and accessories
3.6.7.1
Service life
The rotors and accessories have a limited service life.
WARNING
Perform regular checks (at least once per month) for safety reasons!
• Pay special attention to changes, such as corrosion, cracks, material
abrasion, etc.
• After 10 years, they must be inspected by the manufacturer.
• After 50,000 cycles, the rotor must be scrapped for reasons of safety.
• If other data concerning the service life are engraved on the rotor or
bucket, these data shall apply accordingly. For example, a bucket with
the engraving "max. cycles = 10,000" has a service life of 10,000
cycles, and a rotor with the engraving "Exp. date 02/20" must be
scrapped in February 2020 at the latest (see figure).
• If a specification concerning the maximum number of cycles
and
a
specification concerning the service life (i.e. a date) are provided, the
specification that occurs first shall apply.

life (see chapter 11.3 - " Table of the service life of rotors and

Safety devices
3.7.1
Lid lock device
The centrifuge can only be started when the lid is properly closed. The
electrical lock must be locked. The lid can only be opened when the rotor
has stopped. If the lid is opened by way of the emergency release system
during operation, the centrifuge will immediately switch off and decelerate
brakeless. If the lid is open, the drive is completely separated from the
mains power supply, i.e. the centrifuge cannot be started (see chapter 7.1.1
- "Emergency lid release").
