Opera�on
Mo�on Cuts
When a lifting duty is engaged, the RCI system will protect the machine from moving into unsafe
condi�ons when unstable. The overload alarm will sound at this �me. To aid the driver to recover to a
safe posi�on the system graphics provide a visual indicator of the allowable motions through use of
coloured arrows associated with each hydraulic func�on.
Motions that have
been cut are shown in
RED
.
Motions that are
allowed are shown in
GREEN
.
The RCI uses intelligent algorithms to determine which motions are allowable and will only release valves
to reduce the overturning moments. All motion valves are de-ac�vated when the RRV engine is switched
off. This is a battery saving feature and will show all the arrows as red accompanied by an
“engine off”
message on the front screen.
Axle Lock
The axle unlock is controlled by the RCI system. When the machine is in an axle locked configura�on the
system will calculate if it is safe to unlock the axle on the operator command. If it is unsafe then the axle
will remain locked until the load is reduced. The axle lock icon will be greyed out and a red cross is shown
through it.
Drive Cut
When the machine has the axles locked, and is in Rail Mode, then drive is cut and the machine will not be
allowed to travel. The 3RCI+ will also cut drive in an overload state, or when the brake air pressure is
detected as low. These condi�ons are also only applicable when in Rail Mode.
