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 telescope
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 leading further into
the shutdown range can still take place even after switching off. 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.
