ACTIVATION OF THE GRAPHIC BAR FOR CONTROL SELECTION
Display of the load control system is equipped with a oang bar which shows control buons P1, P2, P3, P4 and P5.
The acvaon of this oang bar depends on the weighing mode selected by the operator:
1) In the ‘AUTO WEIGHING’ mode (see paragraph ‘WEIGHING SCREEN’), when one of the 5 selecon buons (P1, P2,
P3, P4 or P5) is pressed, the system acvates the graphic bar at the boom of display where the executable func-
ons are shown. The operator has 5 seconds to press the buon corresponding to the funcon to be executed. If
no selecon buon is pressed within 5 seconds, the system deacvates the graphic bar.
2) In the 'MAN WEIGHING' mode (see paragraph 'WEIGHING SCREEN'), when one of the 4 selecon buons (P1, P2,
P3 or P4) is pressed, the system acvates the graphic bar at the boom of display where the executable funcons
are shown. The operator has 5 seconds to press the buon corresponding to the funcon to be executed. If no
selecon buon is pressed within 5 seconds, the system deacvates the graphic bar.
If buon P5 is pressed in the manual mode, it does not acvate the graphic bar but it starts a weighing procedure for
the load being lied (see paragraph 'MANUAL WEIGHING' (E)
The funcons corresponding to the selecon buons are the following:
(P1): press buon (P1) to acvate the setup menu for display, where you can adjust both display brightness in the

1) INSTRUCTIONS FOR WEIGHING A LOAD
In order for the weighing to be as accurate as possible, please check that the following condions are met:
1) your machine should always be placed on a at, compact surface
2) your machine should be standing sll, with its wheels aligned with the chassis
3) the telescopic boom should be fully retracted and in a horizontal posion
4) the carriage should be in a vercal posion
5) the recommended weighing mode is the manual one (MANUAL WEIGHING)
In these condions the approximate tolerance of the load readout should be about ±5% of the maximum rated load.
The value of the load being lied is to be considered a mere indicaon for the operator. It has no scal signicance and
it is not a cered weight value.
The following part of this paragraph describes the various funcons of the weighing system.

OPERATING INSTRUCTIONS (SW Version 2.3)
2) RESET (C)
The reset control allows you to delete all the weighing values stored in table 'B'. When all the paral weighing values
are deleted, the overall weighing value is set back to zero too.
To carry out the reset procedure you need to scroll the weighing screen with buon (P2) unl you select 'RESET'. Then
press (P3) to conrm.
The overall weighing value is also shown on the main screen in eld (14). When the RESET command is executed, the
value shown in eld (14) is set back to zero too.
Press buon (P1) to go back to the main screen.

OPERATING INSTRUCTIONS (SW Version 2.3)
3) TARE (D)
This control allows you to tare the weighing system. In this way eld (A) will subsequently show only the weight of the
load being lied, without the weight of the aachment.
To carry out the taring procedure you need to scroll the weighing screen with buon (P2) unl you select ‘TARE’. Then
press (P3) to conrm. The value of the measured weight, expressed in tonnes, appears next to the ‘TARE’ inscripon.
Press buon (P1) to go back to the main screen.

OPERATING INSTRUCTIONS (SW Version 2.3)
4) MANUAL WEIGHING (E)
Use this control to manually weigh the load being lied on the aachment. The data measured by the system are
shown in table 'B', from cell number 1 to cell number 20. Aer 20 weighings all the values scroll up, and the next values
are displayed at the boom of the table. The total at the boom of table 'B' is always the sum of all weighings, including
the ones which are not displayed.
To carry out the manual weighing procedure you need to scroll the weighing screen with buon (P2) unl you select
'WEIGHING'. Then press (P3) to conrm. A tone conrms that the weighing procedure was successfully completed, and
the system stores the value in table 'B'.
To know the sum total of all weighings please refer to the gure next to the 'TOT' inscripon, which is shown in the
boom row of the table; this total increases up to a maximum of 9999.99 t.
Press buon (P1) to go back to the main screen.
NOTE!!! You can also carry out a manual weighing procedure from the main screen by pressing buon (P5); a tone
conrms that the weighing procedure was successfully completed, and the system stores the value. On the main
screen you can also see the total of the weighings, whose value is shown under the load chart in eld (14). The
manual weighing procedure can be carried out from the main screen only if you have previously selected the 'MAN
WEIGHING' item on the weighing screen.

OPERATING INSTRUCTIONS (SW Version 2.3)
5) WEIGHING MODES (F)
Use this control to set the weighing mode:
1) MANUAL
2) AUTOMATIC
Is the manual mode selected, symbol 'X' appears with the 'MAN WEIGHING' inscripon next to it. Is the automac
mode selected, the 'Y' symbol appears with the 'AUTO WEIGHING' inscripon next to it. For the manual weighing pro-
cedure please refer to the instrucons provided in the previous step (MANUAL WEIGHING 'E'), while for the automac
weighing please refer to the following instrucons.
Scroll the weighing screen with buon (P2) unl you select 'AUTO WEIGHING', then press buon (P3) to conrm. Now
you can set a boom li angle beyond which the system automacally carries out a weighing. Such angle should be set
using buons P4 (decrease) and P5 (increase), and should range between 0° and 70°. Once these funcons are set you
need to press buon (P1) and to go back to the MAIN SCREEN, because the automac weighing does not work in the
WEIGHING SCREEN.

OPERATING INSTRUCTIONS (SW Version 2.3)
To conrm that the system was correctly set in the automac mode, eld (14) on the main screen shows the 'Y' symbol
and the value you selected for the boom li angle (in degrees).
In this way, whenever the telescopic boom is lied beyond the angle you selected, the system carries out an automac
weighing (eming the corresponding tone), and stores the value in table 'B'. The sum total of the weighings is always
shown on the main screen, under the load chart and next to the 'TOT' inscripon.
In order to have a new automac weighing available you need to lower the telescopic boom unl it is 5° below the
value you set for the li angle; if not, when you raise the telescopic boom again, the system will not carry out any au-
tomac weighing.

OPERATING INSTRUCTIONS (SW Version 2.3)
6) WEIGHING MODIFICATION (G)
Should you need to either modify or delete one or several weighings stored in table 'B' you can do that using the modi-
caon funcon available on the WEIGHING SCREEN. Scroll the weighing screen with buon (P2) unl you select 'EDIT
DATA', then press buon (P3) to conrm.
Now the manual weighing symbol and an eraser appear under buons (P4) and (P5) respecvely.
To select the weighing to be modied press buon (P2) unl this is highlighted in a ashing mode, then press either
buon (P4) to repeat a manual weighing or buon (P5) to delete the weighing.
Press buon (P3) to conrm your selecon.
Press buon (P1) to go back to the main screen.

OPERATING INSTRUCTIONS (SW Version 2.3)
Your machine is equipped with a 4-posion selector switch
(D) which allows the operator to select -either manually or
automacally- the type of aachment installed on the car-
riage, so as to determine the load capacity chart suitable
for the machine/aachment combinaon.
The 4 posions of switch (D) for the selecon of the type
of aachment installed are the following:
AUTO self-idencaon of the aachment installed on
the carriage
0.5/0.6 aachments where the centre of gravity of the
load being lied is 0.5 / 0.6 metres away from
the carriage
1.5 aachments where the centre of gravity of the
load being lied is 1.5 metres away from the car-
riage
4 aachments where the centre of gravity of the
load being lied is 4 metres away from the car-
riage
The graphic representaon of selector (D) is also shown
on display (A) in the cab, in eld (12) , and it is displayed
when:
- no aachment is installed on the carriage.
- no aachment is idened on the carriage.
- an error/a failure occurs in the aachment self-iden-
caon system
When an aachment is installed and idened on the
carriage and the system works correctly, the graphic re-
presentaon of selector (D) in eld (10) changes over to
the symbol of the aachment installed (see below in this
Chapter).
SWITCH FOR THE SELECTION OF THE TYPE OF ATTACHMENT INSTALLED ON THE CARRIAGE (D)

OPERATING INSTRUCTIONS (SW Version 2.3)
When an aachment equipped with a self-idencaon
sensor is installed on the carriage, you need to shi se-
lector (D) to the "AUTO" posion; in this case the system
automacally determines the appropriate working chart
for the machine/aachment combinaon, thus calculang
the correct stability index, the maximum load capacity and
the safe working area. Then the icon of the idened at-
tachment (a bucket in this case) appears in eld (12).
When an aachment equipped with a self-idencaon
sensor is installed on the carriage but selector (D) is not
shied to the "AUTO" posion, the following acvates:
- red indicator of the LED graphic bar (B)
- red indicator showing the posion of the load on the
dynamic load chart
- warning light on instrument panel
- audible alarm in the cab
In this case the system locks machine controls immedia-
tely and window "X" appears in the middle of display (A)
prompng you to turn selector (D) to the "AUTO" posion.
For the operaon modes of selector (D) please refer to the following instrucons:
SELF-IDENTIFICATION OF AN ATTACHMENT (selector (D) in the AUTO posion)
WARNING!!! The aachment self-idencaon system is disabled if operang mode selector (6) is in the "B" posion
(road travel). In this case you need to turn selector (6) to the "A" posion (movements enabled).

OPERATING INSTRUCTIONS (SW Version 2.3)
If the self-idencaon system works correctly but there is
no graphic representaon of the aachment installed on
the carriage, the machine signals it by showing the corre-
sponding symbol in eld (12) of display (A) in the cab.
MANUAL SELECTION OF AN ATTACHMENT (selector (D) in the 0.5/0.6 or 1.5 or 4 posion)
When either an aachment not equipped with a self-idencaon sensor is installed on the carriage or an error/mal-
funconing occurs in the system, you need to manually select the category the aachment belongs to by operang
selector (D) as follows:
- turn selector (D) to the "A" posion (0.5/0.6) when aachments are installed whose centre of gravity is between
0.5 and 0.6 metres ahead of the carriage
- turn selector (D) to the "B" posion (1.5) when aachments are installed whose centre of gravity is within 1.5
metres ahead of the carriage
- turn selector (D) to the "C" posion (4) when aachments are installed whose centre of gravity is within 4 metres
ahead of the carriage
In this way the machine gets ready to be used with the selected aachment based on aachment category, determi-
ning the work chart and calculang the correct stability index, the maximum load capacity and the safe working area.

OPERATING INSTRUCTIONS (SW Version 2.3)
Field (12) shows the graphic representaon of the posion
of selector (D)
If the selector (D) is turned to the AUTO posion and:
- an aachment not equipped with a self-idencaon
sensor is installed on the carriage, or
- an error/malfunconing occurs in the system
The system automacally acvates the work chart corre-
sponding to the “C” posion (centre of gravity of the load
placed 4 metres ahead of the carriage).
For a beer comprehension of both the self-idencaon
system and the manual selecon of aachments a table is
provided, lisng all graphic representaons shown in eld
