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.”
