This section explains how to access serviceable parts, as well as how to perform some service procedures.
4.1 Testing whether the rotor speed is within the
design tolerance
NOTE: You cannot test the decant speed, but you can change it by changing a global
parameter value. For instructions, refer to the Operation Manual.
You can measure the rotor speed to determine whether it is within the design tolerance.
The cell washer has a sight window in the lid and an optical reference on the rotor so that you can easily
measure the speed of the rotor during operation.
When the rotor is programmed to spin at 3500 r/min (RPM), the measured speed should be
3500 r/min ± 20 r/min.
For more information and instructions to program and use the cell washer, refer to the Operation Manual.
You will need the following to test the rotor speed:
► Laser tachometer (calibrated and capable of measuring r/min)
!
WARNING: Prior to using the laser tachometer, review all safety and usage instructions
provided by the manufacturer.
To test whether the rotor speed is within the design tolerance
NOTE: Regulations for your organization may recommend test methods different from
what appear here. Use the appropriate methods for your organization.
1 Install the rotor.
2 Program the Spin (S) program with a spin speed of 3500 r/min and a spin time that is long enough for
you to measure the speed.
3 Start the Spin (S) program by pressing the SPIN button.
4 While the rotor is spinning and 3500 is displayed on the message screen, point the tachometer’s laser
beam through the sight window on the lid. As the rotor spins, the laser momentarily reects off the
optical reference on the rotor.
5 Obtain the reading from the tachometer. If the speed is not within the tolerance of 3500 r/min ± 20
r/min, follow the appropriate troubleshooting steps to determine how to proceed.

4.2 Testing whether the imbalance value is in the
permissible range
The imbalance microswitch senses whether the rotor is balanced during operation. If the rotor is not
balanced, an imbalance error results. The weight at which the imbalance error occurs is the imbalance
value.
At the factory, the microswitch is positioned to allow an imbalance value that lies between 5 g and 10 g
when the rotor is spinning at 1500 r/min. For example, if the imbalance value were 7 g (the middle of the
range), an imbalance error would result only if one side of the rotor were more than 7 g heavier than the
other. One gram is approximately equal to 1 ml of saline solution.
Continual operation of the cell washer when the imbalance value of greater than or equal to 10 g may
damage the cell washer. An imbalance value of less than or equal to 5 g is overly sensitive to the normal
variations in weight that occur during operation.
For more information and instructions to program and use the cell washer, refer to the Operation Manual.
You will need the following to test whether the imbalance value is in the permissible range:
► Tubes (enough to ll all available positions on the rotor)
► Saline solution. One test run requires 15 g (approximately 15 ml)
► Scale (calibrated and capable of measuring 10 g)
To test whether the imbalance value is in the permissible range
NOTE: Regulations for your organization may recommend test methods different from
what appear here. Use the appropriate methods for your organization.
1 Add tubes to all the available positions in the rotor. If you are using 10 mm x 75 mm tubes, conrm
that the tube inserts are installed correctly in all the tube holders.
2 Program the Spin (S) program with a spin speed of 1500 r/min and a spin time of 20 seconds.
3 Test whether the imbalance value is below the upper limit of the permissible range.
a Starting with empty tubes, add a total of 10 g of saline solution to one or more tubes on one side of
the rotor.
b Install the rotor.
c Start the Spin program. If the program completes without an imbalance error, then the imbalance
value is too high and must be decreased. For instructions, see Section 4.3, “Adjusting the
imbalance microswitch.”
4 Test whether the imbalance value is above the lower limit of the permissible range.
a Add a total of 5 g of saline solution to one or more tubes on one side of the rotor.
b Install the rotor.
c Start the Spin program. If an imbalance error occurs, then the imbalance value is too low and must
be increased. For instructions, see Section 4.3, “Adjusting the imbalance microswitch.”

4.3 Adjusting the imbalance microswitch
NOTE: For more information about locating and identifying parts, see Section 5, “Parts”
and Section 6, “Schematic.”
The imbalance microswitch senses whether the rotor is balanced during operation. If the rotor is not
balanced, an imbalance error results.
The proximity of the microswitch to the motor shaft determines the value at which the rotor is considered
to be imbalanced. The higher the imbalance of the rotor, the closer the motor shaft moves toward the
microswitch during operation.
You may need to adjust the imbalance microswitch in the following circumstances:
► The imbalance value is outside of the permissible range.
► Imbalance errors continue to appear, even after you have addressed other possible causes.
► You replaced the imbalance microswitch.
You will need the following to adjust the position of the imbalance microswitch:
► #15 TORX® screwdriver
To adjust the imbalance microswitch
1 Remove the rotor from the cell washer, and close the lid.
2 Turn off the cell washer and disconnect it from power.
3 Turn the cell washer so that it rests on the left side.
4 On the bottom of the cell washer, use the screwdriver to loosen the screw in the slot. This screw
secures the imbalance microswitch bracket to the base.

5 Do one of the following:
► To decrease the imbalance value, slide the screw toward the center of the cell washer. The switch
moves closer to the motor shaft.
► To increase the imbalance value, slide the screw away from the center of the cell washer. The
switch moves farther away from the motor shaft.
6 Tighten the screw to secure the imbalance bracket to the base.
7 Test the imbalance value to ensure that it in the permissible range. For instructions, see Section 4.2,
“Testing whether the imbalance value is in the permissible range.”
