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).

Dig Mode
When the excavator is not being used for liing operaons then the 2RCI should be switched
into dig mode. In dig mode the alarm is muted and any moon cuts (if ed) will not be acvated in the
event of an overload situaon. While in dig mode, the 2RCI provides a guide to levelling or trenching.
The 2RCI will prompt the operator to conrm that they
want to switch into Dig Mode.
To enter Dig Mode, press on the dig buon.
Pressing “YES” will switch the 2RCI into dig mode and the main screen should now look like this:
Current Dig Depth

Dig Mode connued...
The system will ask you if you want to enter a depth
using the on screen keypad. Press “YES” to access the
keypad. Enter a depth that is relave to the base point
of the boom and press enter. Press exit from the
keypad to deselect the dig mode.
Depth Seng
To adjust or set the dig depth, press on the buon which is in the Mode Menu.
Pressing “NO” will allow the operator to use the
posion entry mode.
Place the bucket at the level required and press “YES”.
The system will now use this posion as the target
depth.
When in digging mode the system provides a level indicator. The indicator shows the target level.
There are three states for the indicator, as shown below:
Above Target Level Below Target Level On Target Level
NOTE - The depth indicaon is measured to the load point. The orientaon of the bucket will aect the
accuracy of the indicator. Moving the machine from one level to another will change the depth of a
trench. Whenever the machine is moved it is recommended that the depth is reset by placing the bucket
on the level previously dug and reset the depth by pressing dig mode, “NO” and “YES” to make the new
bucket posion to datum.

Automac Slew Based Liing Dues
The 2RCI system may oponally be equipped with an addional module to monitor the slew posion of
the turret relave to the machine undercarriage, and automacally select li dues based on the slew
posion of the turret.
Current duty in use, and the current slew posion of
the turret relave to the undercarriage, are
indicated on the 2RCI display.
Current Slew Duty (SU1 - SU5)
Current slew posion of the
turret in degrees (0°-360°)
Typically, eight slew “dues” are available. The dues are named SU1 - SU5, with each duty having it’s
own calibrated “p” point for the machine.
As the turret is slewed the appropriate li duty for
the slew posion is automacally selected, and the
li capacity calculated by the RCI will be adjusted
for the slew posion of the machine based on the
duty in use.
Thus, more li capacity can be aained for the
machine over the front and rear than over the side,
and the machine’s li capability is maximised for
the slew posion of the machine.

GKD Technik LtdM2000001
Full Moon Cut on Overload
The 2RCI can be oponally equipped with an addional I/O module, which enables the 2RCI to control
addional moon cut valves. This makes it possible to oer full intelligent moon cut of boom funcons
on overload to prevent the machine from being moved further into an unsafe overload state. All boom
funcons that will reduce the li radius and move the load to a safer posion remain enabled.
An indicaon of boom moon cut status is shown
by a series of colourised dots on the machine
graphic. On moon cut, the dot that symbolises any
hydraulic funcon that would take the system
further into overload.
In normal operaon, these dots will be green.
This indicates that moon are allowed.
When in overload, these dots will turn red. This indicates
that moon is prevented (the moon is cut).
Test Funcon
Pressing the “TEST” buon will acvate the internal and external alarms and operate any moon cut
valves that may be connected for a period of around ve seconds. The test buon sequence should be
carried out regularly to verify the correct operaon of warning devices.
To access the “TEST” buon, rst press the “MENU” buon.
Then you can press on the “TEST” buon.
