Quick Answer

You may get this error for a couple of reasons:

1. The lever you were trying to calibrate may not have been in the correct position when you pressed the calibrate button"
2. The lever was in the correct position but the value returned by the RailDriver was outside the expected values.

For more information please check the Further Reading section below.

Further Reading:

The lever you are calibrating is not in the correct position:

If you accidently press the calibrate button before you finish moving the lever into the correct position you will receive the "calibration out of Bounds" error.

This error can usually be resolved by moving the lever into the correct position and pressing the calibrate button.

If this error occurs while calibrating the bail-off for the independent brake press the brake lever to the right and hold it in this position before attempting to press the calibrate button again.

The lever you are calibrating is in the correct position:

If you're confident that the lever is in the correct position but you are still receiving this message then the RailDriver may be reporting a value that is outside of the expected values for that lever position. This is not a common occurence, but has been known to happen.

If you believe this is what is happening with your RailDriver please follow the instructions below to disable the bounds limits and manually calibrate the RailDriver:

1. Go to 'Start > Programs > RailDriver> RD Calibration.'
2. Click on the 'Help' tab and then on 'About.'
3. In the next window, click on the word: 'copyright.'
4. Click 'OK' to see message: 'Bound limits disabled.'
5. Click on 'OK' in the 'About' screen and begin to calibrate.
6. After calibration, return to the 'About' window.
7. Click on 'copyright' to see message: 'Bound limits enabled.'

Now that your RailDriver has been manually calibrated it should be ready for use.
