  • Page 31: Equipment Overview

    Treadmill has fewer moving parts than other treadmills, built-in self-calibration, and replaceable assemblies. Intended Use The T2100 Treadmill is intended for use with any one of the several GE Healthcare exercise testing systems for administering a controlled exercise load during a diagnostic stress test.

  • Page 32: Drive Controller System

    The T2100 Treadmill can accommodate a weight capacity up to 450 lbs. Elevation System The elevation system uses a rack and pinion operation to raise and lower the T2100 Treadmill rather than jack screws and chains. The elevation motor attaches to a small gearbox that connects to the pinion shaft.

    250 VAC. Operation The processor board’s main task is to monitor the proper T2100 Treadmill operation by testing selected variables from the system. In case of any variable operating out of specs, the firmware will first detect the event, then log it, and finally stop any further operation.

  • Page 66: Self-Calibration

    T2100 processor board that has never been calibrated. ESTOP In order to operate the T2100 Treadmill, the ESTOP plug must be attached to its receptacle on the processor board.
