E2 Cal - True Fitness TREADMILL 2011 Service Manual

 This error will occur if the upper and the lower boards lose their
calibration parameters. See calibration procedure(pg 47)
Note: May be caused by speed fluctuation.
•Check for high friction by performing a Push-off test
•To perform this test raise the elevation to the highest level and
remove safety key.
•While standing on the belt push away from the handle bar.
•If there is high friction between the belt and deck it will be difficult
to push away.
•Units with low friction will be easy to push away.
•High friction can lead to excess amp draw on the motor. The
motor may overcompensate causing an error code. If this is not
addressed, it will lead to motor controller failure.
•Replace running belt and deck as needed
•Check the line voltage for fluctuations. This can cause erratic
speeds.
