6.1.8. ADC Automatic Duty Control
The purpose of the ADC feature is to increase the lifting
capacity by 10%.
The first boom pressure sensors indicate if there is a
positive or negative pressure on the first boom.
Normal capacity
• If the first boom is pressed down, the sensors indicate a
negative pressure and the lifting capacity is normal
during the complete lifting cycle.
Increased capacity (ADC mode)
• ADC lamps light up.
If the sensors indicate a positive pressure, the lifting
capacity is increased during the complete lifting cycle.
6.1.9. PFD Pump flow distribution
When operating several functions simultaneously the pump flow may not be sufficient. PFD will
now take over, reducing the speed of all operated functions. Uncontrolled movements are thus
avoided, smooth simultaneous operation is achieved.
6.1.10. Slewing sector [option]
Within slewing sector, lifting capacity can be reduced due
to stability. The overload warning will be given at a lower
load in the limited sector than outside the sector. In case of
an overload warning you may slew out of the sector but not
further into it.
