Introducon
This is the operaon manual for the 2RCI range of rated capacity indicators.
This product is a safety product.
WARNING - DURING NORMAL OPERATION THE RATED CAPACITY OF A CRANE SHOULD NOT BE
EXCEEDED. THEREFORE THE OVERLOAD WARNING SHOULD NOT BE USED AS A NORMAL MODE
OF OPERATION. STATUTORY REQUIREMENTS DO NOT PERMIT THE RATED CAPACITY TO BE
EXCEEDED EXCEPT FOR THE PURPOSE OF TESTING.
THIS RCI IS NOT FOR USE IN EXPLOSIVE ATMOSPHERES.
ADJUSTMENT BY NON AUTHORIZED PERSONNEL WILL INVALIDATE THE WARRANTY.
Operaon
The 2RCI system is wired to automacally start whenever the machine is started. There is no operator
ON/OFF control. At switch on the system will inially show a blank screen and the green LED on the front
panel will blink. Once self tests are complete the indicator screen will illuminate. The system will
automacally start in the li mode.

Liing Operaon
In liing mode the 2RCI system displays the current radius and height of the liing point and the related
maximum rated capacity. The status graph shows the current load relave to the maximum. The red and
amber LEDs on the front panel provide an indicaon of approach to and exceeding of rated capacity. An
external and internal (where ed) sounder will also indicate the current status.
Liing Dues
The 2RCI system may be calibrated to provide liing capacity rangs for dierent conguraons of
machine. The switching between dues may be automac via external limit switches or automacally
selected from machine slew posion (slew module opon only), or manual via the ‘MODE’ screen.
The liing duty number is shown on the front screen.
Selecon of Li Aachment - Opons
2RCI supports the use of Forks or Demountable Jibs for liing and height liming purposes.
In the standard conguraon, only the Bucket Pin is dened as the li aachment, and no other selecon
is available unless they have been enabled and set up within the system calibraon menus.
Manual Liing Duty Selecon (Jib and Forks Versions)
Selecon of the liing mode is made from the MODE screen. Access to this screen is by pressing the
MODE buon on the front screen. There are three available li conguraons. The mode is selected by
repeatedly pressing the coloured li duty buon.

Liing Mode
Hook/Bucket duty
This is the standard excavator liing conguraon.
The radius and height are measured to the bucket
pin on the sck and all calculaons of rated capacity
are referenced to this posion. The front screen of
the indicator will show a duty status ‘hook’.
Jib duty
When the extension jib is ed to the machine this
duty adjusts the liing capacity to be measured at
the end of the jib. The front screen will show a ‘JIB’
status. In addion there is a warning if the hydraulic
pressure is exceeded in the jib cylinder.
Forks Duty
When the forks are aached to the machine the
system will provide a height and radius oset
to the posion of the load on the forks. As well as
showing a duty status of ’forks’. In addion there is
an automac height limit applied to the fork mode.
This height limit is pre-set at 2.5m (the screenshot
to the right shows the status and height limit).

Seng a virtual wall by entering a distance
Press on the “Set Virtual Wall 1” buon.
Then press on the “Le Wall” buon.
A keypad will open for you to enter the distance to
the le wall, in metres.
Enter the distance and press ok.
The screen should now change back to one similar
to that pictured to the right.
The “Set Virtual Wall 1” buon will now be greyed
out. Pressing on this buon will acvate the virtual
wall and the buon will change to indicate that the
virtual wall is not acve.
The screen pictured to the right, shows a virtual wall
set and acve.
The screen pictured to the right, shows the main
operator screen once the virtual wall has been set
and acvated.
The top right corner of the display will show where
the virtual wall is in relaon to the machine. It will
also show the distance to the virtual wall from the
machine.
As the machine slews, its posion and distance to the wall will be updated automacally.
When the machine reaches the virtual wall, all relevant machine moons will be prevented from
breaching the wall. This includes Boom and Dipper moons.
