Liebherr Crane Starts, but Will Not Operate

Remote will start the crane, but no functions work.  Display shows Trolley Position, Hook Height and Slew Angle, but no functions work.  See screen:

Note left arrow.  M511 means wind zone is not confirmed (1st clue, see “M” codes in Liebherr folder).  Right arrow indicates trolley position, but does not indicate jib length (the 0.0 below position).  Go into scaling (key switch CCW to scaling) and press F3 for scaling summary.  All icons should have a checkmark next to it.

Liebherr Scaling Screenshot

Any icons that have a “X” next to it need to be reconfirmed.  F1 to previous screen, and F2 to confirm each icon.  Must confirm the OK at the end as well.

Operator called and said crane won’t move.  Turns out he turned the key in control panel for the 125% test.  This erases the scaling data.  What you have to do is turn scaling key and go through and make sure everything is check marked and then a check mark at the end and hit enter.  Once this is complete you can switch switch out of scaling and it will work.
