PCS2 Service Manual
1. Remove the front and rear panels. (See page 2-2.)
2. Using a #8 hex bit, remove the (4) shoulder screws securing the
centrifuge base to the centrifuge mounting fluid drain assembly.
3. Disconnect P404 and P406 from the centrifuge distribution card.
4. Disconnect the ground braid wire clamps Phillips head screws at the
rear of the cabinet.
5. Remove the (2) optic cables from the photoelectric assembly by
unscrewing the (2) plastic thumb screw fasteners.
6. If present, you may need to remove a retaining screw located at the
front, right side of the centrifuge mounting fluid drain assembly.
7. Disconnect the ground wire located in the rear of the centrifuge.
8. Disconnect J3 from the centrifuge controller card at the front of the
cabinet.
9. Carefully lift the centrifuge up and away from the top deck of the
cabinet.
Centrifuge Reassembly Notes
1. The centrifuge must be centered in the top deck cavity to prevent contact
of the centrifuge with the cabinet during operation. If true centering cannot
be achieved, ensure that the centrifuge is at least 1/16" from the cabinet,
measured at four points separated by 90 degrees.
2. The centrifuge location is adjusted by loosening the four centrifuge
mounting screws under the cabinet, and manipulating the centrifuge
on the centrifuge mounting fluid drain assembly.
3. Install the centrifuge on the centrifuge mount, and tighten the four
shoulder screws.
4. Adjust the centrifuge location, then tighten the four screws and
recheck location of centrifuge.
5. Recalibrate the centrifuge and bowl optics, referring to the procedures
in Chapter 4, Calibration.
Cover Halves
1. Open the centrifuge cover halves.
2. Using a #8 hex bit, remove the (1) shoulder screw securing each cover
half and pull the cover away from the cover hinge.
3. The centrifuge cover halves are a matched pair. It is very important
that the components of each cover half are kept together if the cover
halves are to be disassembled further.
