LC-Display

The LC Display has five digits. The
readout depends on the operating modus
and the operator’s selection.
Please refer to section 4, Operation of the
system.

Load Moment Limit Light

The red LOAD MOMENT LIMIT LIGHT (2) warns the
operator that a rated load condition has been
reached. It lights up when the load on the crane
reaches the crane load capacity. The audible alarm
also sounds when this condition has been reached.

Load Moment Prewarning Light

The yellow LOAD MOMENT PRE-WARNING LIGHT
(3) will light up when the load on the crane reaches
the defined prewarning area, thus indicating that an
overload condition is approaching.

This means for the operator to continue his crane
operation with extreme caution.

Alarm Light “Anti-2-Block”

The red “Anti Two-Block Alarm Light” (4) lights up
when the anti-two-block limit switch contacts open,
indicating that a two-blocking condition is
approaching. At the same time, the audible alarm will
sound, and the telescope out and winch up functions
are locked out. If machine is equipped with an
overload shut-off, the boom down function is also
locked out.
