OLP boom system
When 100% of the maximum permitted pressure is
reached, OLP cuts in and stops all functions that increase
the pressure. On the lamp pole, if present, the red lamp
and amber lamp will light continuously.
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.

XSDrive
OLP boom system:
The cylinder LEDs indicate a
percentage of maximum pressure:
• 70% of maximum pressure reached - lower LED on each
cylinder light green
• 90% of maximum pressure reached - lower LED on each cylinder flash red
• 100% of maximum pressure reached - both LEDs on each cylinder light red
CombiDrive
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.
