OLP boom system shown on the left and right
displays:
• A percentage of maximum permitted pressure
in the cylinders is shown on the displays.
When 50% or more of maximum pressure is
reached, the percentage alternates with the
function symbol once a second in the display
corresponding to each lever. The display
shows 50%, 70%, 90% and 100% as the
pressure increase.
• 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) func-
tions only. In an OLP situation, symbol "x" is
shown in every menu in the centre display.

To release OLP
If all functions have been blocked due to OLP it
is possible to temporarily release OLP and oper-
ate 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!
