Processor Card
1. Remove the rear panel. (See page 2-2.)
2. Unclasp the card levers and unplug the processor card from the
backplane card (located at far left of the card cage).
3. Slide the card out of the card cage.
4. If replacing the processor card, refer to Chapter 4 for calibration of
the bowl optics signal, line sensor signal, A/D, centrifuge, and safety
system, and Chapter 5 for configuration.
Note: Processor card MUST have Main Program IC (P/N 37008-01) chip
in position U26 prior to reassembly. Also, verify that the correct
program version for your facility is installed. If program version is
not correct contact the Haemonetics Hot Line.
Main Program Chip Assembly
1. Remove the processor card. (See above.)
2. Using an antistatic IC removal tool for a 32 pin IC, gently pull the
main program IC from chip location U26. A future program upgrade
may also utilize U23. If the IC removal tool is not available, use flat
blade screwdriver to gently pry between IC chip and IC carrier from
end to end until IC chip is out.
Note: Do NOT bend IC chip legs.
Main Program Chip Reassembly Notes
The Main Program IC chip must be installed properly or the chip will be
destroyed. At one end of the chip there is a small notch (half circle). This
notch must align with the white notch silk-screened on the Processor card
(notch points toward the backplane connectors).

2. Unclasp the card levers and unplug the safety card from the backplane
card (located as second card from the left in the card cage).
3. Slide the card out of the card cage.
4. If replacing the safety card, refer to Chapter 4, Calibration, for
calibration of the safety system.
