Rotor Reassembly Notes
When placing the rotor back into the pump housing, ensure that the slot
on the underside of the rotor is aligned with the pin on the pump motor
shaft. Do NOT overtighten the rotor screw.
Motor
1. Remove the pump assembly. (See page 2-10.)
2. Remove the pump rotor assembly. (See page 2-10.)
3. Using a 7/64" hex wrench, remove the (4) #6-32 socket head screws
securing the pump housing to the pump motor. (Mark the position of
the motor on the pump housing. This is functionally unimportant but
will keep the reassembly process consistent).
4. Gently twist the pump head and lift it from the motor.
Caution: Do not attempt to disassemble the pump motor. Serious
damage to the motor may result.
SPM/DPM Sensor Assembly
Note:
List number 06002-110-NA machines do not have the SPM.
Note:
The SPM/DPM is not utilized by the PCS2 safety system for
Platelet Poor Plasma (PPP) collection.
Note:
With a thin wall socket, and a bit of experience, you may be able to
remove these sensors without removing the top deck.
1. Remove the rear panel. Remove the top deck (page 2-6) or remove the
Blood Pump Assembly.
2. Disconnect P603 (for the SPM) or P604 (for the DPM) from the top
deck distribution board.
3. Remove the ground wire from the SPM/DPM sensor assembly.
4. Remove the (2) nuts securing the SPM/DPM sensor assembly to the
top deck.
5. Pull the SPM/DPM sensor assembly out of the top deck.
Note: The procedures in steps 6 and 7 should not be performed unless the
SPM/DPM sensor board is being replaced.
6. With or without first removing the SPM/DPM sensor assembly from
the top deck, remove the (2) Phillips head screws securing the
SPM/DPM sensor board to the SPM/DPM sensor assembly.
7. Gently twist and pull the SPM/DPM sensor board from the
SPM/DPM pressure fitting.
8. We do not advise further disassembly of the SPM/DPM sensor
assembly.
9. If replacing the DPM, recalibrate the DPM and Safety System,
referring to the procedures in Chapter 4, Calibration.
