problem with the closed loop scanner

Hi.

Im working with a Dimension 3100 AFM microscope with a Nanoscope IV controller, equipped with a closed loop XY-scanner. The software version is the Nanoscope 6.13R1.
When I work with the closed loop 'on', I'm not able to engage the tip because the following error message appears after the pre-check engage:
CLOSED LOOP ERROR - Could not sense motion in X-check connections.
Instead, I can normally approach when the closed loop is disabled.
Is there something that I can check to understand which is the problem?

Thanks.

Chiara
