  • Page 49: Walking Belt Tracking And Tension Adjustment

    If the belt tracks to one side or the other, then you must adjust the belt tracking. It is not unusual for the GE T2100 Treadmill belt to move slightly off center while a person with a heavy gait is exercising. A properly adjusted belt re-centers itself when the person steps off the GE T2100 Treadmill.

    Initial Board Conditions The power board initial conditions are all at 0V. Power Input Requirements The GE T2100 Treadmill is used on single phase AC. The specific power ratings are 200-240VAC, 50-60 Hz, 16A. Power Distribution/Isolation The power board receives 200 to 240VAC power (nominal 220V). The isolation transformer supplies 12V to two switching regulators.

  • Page 55: Power Supplies

    These capacitors provide 3.3 Farads of capacitance that give the processor board power to logically power down activities in case of a loss of power to the GE T2100 Treadmill. Processor Board Connectors The power board has two connectors that directly interface with the processor board.

  • Page 56: Elevation Sensor

    The I/O connectors on the power board have current-limiting resistors, Zener diodes, or filtering capacitors wherever possible to prevent EMI from escaping the board. These components also limit rise-time and voltages which may come from ESD or other noise sources. GE T2100 Treadmill Revision A 2021403-031...
