Ensure Initial Operational Integrity
Power on the PCS2 and ensure that it passes the initialization and safety
system test before going on to test the machine. (This will ensure that the
machine was operational before it was tested and alleviate any doubt
whether the service technician’s adjustments caused a problem should the
machine fail to operate properly after the PM is complete.)
Record the Program Revision Level
The program revision level is displayed on the screen just after the
centrifuge interlock switch is tested during the self test of the machine.
Watch for this revision level after you complete the locking and unlocking
of the centrifuge cover as instructed on the display by the machine.
Refer to Chapter 8 for cleaning procedures.
Electrical Connections Inspection
1. Remove the front and the back panels to gain access to the internal
components.
2. Inspect for loose or broken electrical connections on all major
assemblies. Tighten or repair as required.
Pneumatic Connections Inspection
Inspect the pressure connections at the cuff compressor and in-line filters.
Tighten and repair as required.
Hardware Inspection
1. Inspect for loose or missing mounting hardware. Tighten and repair as
required.
2. Inspect the centrifuge drain tubes for proper placement. Ensure that
there is unobstructed passage for fluids from the centrifuge.
3. Inspect the centrifuge mounting location to ensure that the centrifuge
does not contact the deck. There should be a clearance of at least 1/8
of an inch between the centrifuge and the cavity in the deck all the
way around the centrifuge, and a visible gap between the base of the
centrifuge rim and the deck surface.
