pulling the tubing off the shaft if it is pressed on too far (see caution
statement).
4. While looking at the shaft end of the potentiometer, rotate the shaft
CCW until it stops. Then rotate the shaft 1–2 turns CW.
5. Attach the harness assembly to the unit by guiding the
potentiometer (with tube attached) through the clearance hole in the
chassis tower. Make sure the harness assembly is oriented such that
the mounting plate holes are in general alignment with the threaded
stand-offs. This must be done in order to maintain the 1–2 turns
established in Step 4. Also be sure that the cables are toward the
rear of the GE T2100 Treadmill. Attach the tube far enough on to the
elevation shaft such that the mounting plate is within 1/16th inch or
less of the threaded stand-offs.
6. Secure the mounting plate with the appropriate screws.
7. Connect the other end of the harness to the Control PCB as required.
8. Power on the unit and run calibration to ensure proper operation of
elevation system.
9. Test the GE T2100 Treadmill using the CASE system (or other
controlling device) to ensure the GE T2100 Treadmill is capable of
reaching its lower and upper limits. Confirm that the requested vs.
actual elevation (as reported by the example CASE application
screen below) match at 0% grade and at 25% grade. If the actual
elevation does not reach 25% grade, the 1–2 turns preset established
