Stub Release
It is possible to get the machine into a situa�on
where the indicator will lock motions such that the
machine cannot be moved. Specifically, this can
occur when the stub boom is li�ed un�l the end of
the li� ram travel occurs. At this point a pressure
can be induced into the ram that exceeds the
pressure that would be induced by a rated capacity.
In this case, lowering the boom may increase the
radius of the load (even if there is no load - the
indicator is unaware of the difference) and the
indicator will shut off this circuit.
To allow recovery there is a �med override facility.
Select MENU -> Stub Release
. Lower the boom slightly to release the trapped pressure and the machine
will be operable again.
Dig Mode
The system has a func�on to allow the machine to be used for digging. The actual opera�on of the
digging mode is slightly different between rail mode and road mode.
Rail Mode
When digging on the rail it is preferable not to li� the rail wheels from the rail as the impact of the wheel
returning to the track a�er a breakout opera�on may result in damage to the track. Dig mode will disable
the motion cut on overload func�ons, the external alarm on overload will be disabled and the beacons
will indicate non li� du�es. The display will s�ll show the loading and overload status of the machine but
will not intervene on overload. Use of dig mode is recorded in the system data log. Site personnel will be
warned that the RCI is not opera�ng and is in Dig mode by the lack of illuminated beacons.
Road Mode
The system is inopera�ve as an RCI and external alarms and beacons are disabled. There is no protec�on
against overloading or �pping.
