16.9 XP DEVICE
The XP device works on the principle of an increase in the lifting capacity of
the crane with a reduction in the dynamic effect achieved with a reduction in
the speed of certain movements.
Furthermore the XP device can be used, not just to increase the capacity
crane:
- but to exploit the reduction in the speed when moving a load that must
be positioned with precision.
- and to exploit the variation in the lifting moment limiting device adjust-
ment parameters to exit from a critical situation when moving the load
(overcoming of the 90% or intervention of the lifting moment limiting
device).
(!) ATTENTION (!)
When the XP device is enabled, respect what is indicated on capacity
plates marked with F ….XP
16.9.1 Activation and instructions for use of the XP/CR
device
The XP/CR device can be activated only through the push-button panel of the
radio remote control by using the appropriate rotary selector shown in fig. 10.
The activation of the XP/CR device is indicated with the mark XP displayed on
the radio remote control and on the graphic panel (if fitted); furthermore the
warning light over the XP button of the alphanumeric panel (if fitted fig. 11) and
of the panel (if fitted, fig. 12) comes on.
NOTE: the XP buttons on the control panels are ineffective.
NOTE: when the XP is activated, the distributor can be enabled only through
