OLP boom system
When 100% of the maximum permitted pressure
is reached, OLP cuts in and stops all functions
that increase the pressure.
The pressure level in the first and second boom is
indicated by the LEDs on the user interface:
• 50% of maximum pressure – 1 of 4 LEDs
light green
• 70% of maximum pressure – 2 of 4 LEDs
light green
• 90% of maximum pressure – 3 of 4 LEDs
flash red
• 100% of maximum pressure – 4 of 4 LEDs
flash red
! NOTE
Do not operate heavy loads with the extensions
fully retracted. In an OLP situation it is an
advantage to be able to retract the extensions.
OLP manual control
If one prohibited function is used, all functions
will stop. The crane will be fully operational as
long as only allowed functions are used.
6.2.2 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.
