Jcf-Z Rotor Identification - Beckman Coulter Avanti J-20 XP Instruction Manual

JCF-Z ROTOR IDENTIFICATION

The rotor identification system can, under two specific conditions,
misidentify the JCF-Z continuous flow/zonal rotor. Misidentification
has occurred if a rotor name other than JCF-Z appears in the ROTOR
display during the run, when rotor identification is complete. If the
rotor is misidentified, stop the run and follow one of the steps below.
NOTE
Misidentification can be prevented by returning
your JCF-Z rotor to the Beckman Coulter
factory to have magnets added to the rotor body.
The magnets ensure correct rotor identification.
Call your local Beckman Coulter Field Service
representative for more information.
JCF-Z rotors manufactured after March, 1997,
have factory-installed magnets.
• On the first few uses of a new JCF-Z rotor, or in an older JCF-Z
rotor with newly replaced bearings, run the rotor from 0 to
5000 rpm and back to 0 rpm three times. This procedure will
distribute lubricant around the bearings in the rotating seal
assembly, reducing drag.
• In older JCF-Z rotors with bearings that have not been replaced
recently, follow the same procedure as for a new JCF-Z rotor
(perform three runs from 0 to 5000 rpm and back to 0 rpm) to
ensure that the bearings are properly lubricated. If misidentifica-
tion recurs after the third run, when the bearings are lubricated,
this indicates that the bearings are worn and need to be replaced.
Replace the bearings following the instructions in the JCF-Z
manual (JCFZ-IM).
NOTE
If the JCF-Z rotor is misidentified, the run speed
will be limited to the maximum speed for the
identified rotor. (The maximum speed for the
JCF-Z rotor is 20 000 rpm.)
