• When pressure reaches 100 %, all functions that
would increase pressure are blocked. If the operator
attempts to operate a blocked function, the function
symbol is replaced by a cross while the lever is
engaged. When the lever is returned to neutral
position, the cross disappears and the function symbol
returns. Operate permitted (pressure reducing)
functions only. In an OLP situation, symbol "x" is
shown in every menu in the centre display.
6.3. To release OLP
If all functions have been blocked due to OLP it is possible to temporarily release OLP and operate
an appropriate crane function to correct the overload situation. OLP release is active in 5 second
intervals. After each 5 second interval of OLP release there is a wait before the release operation
can be activated again. The wait will increase in three steps: 30, 60 and maximum 90 seconds.
During each 5 second interval only one function at a time can be operated. Extension out cannot
be operated at all. The 5 second interval starts to count down as you move the lever.
DANGER
Only use the OLP release to get the crane out of a locked position. Never use the
OLP release to overload the crane deliberately!
NOTE
In case of a crane breakdown, the use of OLP release will be part of the
investigation. If the use of OLP release is too excessive it might affect warranty.
