The displayed values are purely numeric values from the rotary encoder
and can be positive or negative. The values have no relationship to the
actual hook height and are only used for limit value acquisition during the
current lift.
Entering limit values
The values for the hoist rope limitation may not be entered until the tele-
scope status and the boom position for the application have been rigged.
If you change the telescope status or boom position after entering values for
hoist rope limitation, then the
RCL display will show an error message;

Risk of accident due to incorrectly set limit values
When entering the limit values, please note that movements can still take
place even after switching off, which lead further into the shutdown range.
Before crane operation, slowly approach all limit values, check that they are
shutdown in good time and, if necessary, enter new limit values with larger
safe distances.
