INTRODUCTION
• MANUAL USE MODES
The section of this manual dedicated to the installation contains information for installers. For this reason we have used technical terms without
providing explanations which would be necessary for end users only.
THE INSTALLATION MUST BE CARRIED OUT BY AUTHORIZED AND SKILLED PERSONNEL ONLY. ARAG IS NOT RESPONSIBLE
FOR ANY OPERATION SPECIFIED IN THIS MANUAL CARRIED OUT BY UNAUTHORIZED OR UNSKILLED PERSONNEL.
• LIMITATIONS
The descriptions of the assembly phases refer to a "general" Virtual Terminal, so specic models will not be mentioned, unless a certain installation
procedure concerns exclusively one VT type.
• RESPONSIBILITY
The installer must carry out "workmanlike" installations and ensure to the end user the perfect operation of the whole system both with ARAG
components only and other brands' components.
ARAG always recommends using its components to install control systems.
The installer will be held responsible for any malfunction if he decides to use other brands' components even without actually changing the system
parts or harness.
The compatibility check with components and accessories of other manufacturers shall be carried out by the installer.
If the ARAG components installed together with other brands' components get damaged because of what stated above, no direct or indirect warranty
will be provided.
1 RISKS AND PROTECTIONS BEFORE ASSEMBLY
All installation works of IBX100 control unit, except the main connection (Refer to the manual supplied with IBX100 ISOBUS Hydraulic
- Chap. Settings > AUX conguration)must be done with battery disconnected, using suitable tools and any individual protection
equipment deemed necessary.
Use ONLY clean water for treatment tests and simulations: using chemicals during simulated treatment runs can seriously injure
persons in the vicinity.
DO NOT WORK NEAR THE BOOM WHILE THE BLC CONTROL SYSTEM IS IN OPERATION.
2 PRODUCT DESCRIPTION
The BLC kit is the system for boom leveling control (BLC) that allows keeping the sprayer arm parallel to the eld orientation and managing its distance
from the ground through the dedicated control unit - IBX100 hydraulic control unit- so as to ensure an even spraying covering.
Since the BLC control is an hydraulic function of the machine, an IBX100 Hydraulic ISOBUS control unit is required.
The control unit could be previously installed to control other hydraulic functions on the machine.
If you do not have any control unit, order separately an IBX100 hydraulic control unit and the relevant connection cable.
To enable IBX100 Hydraulic ISOBUS for the use of BLC, ask for the activation code to ARAG (“9.1.1 Activation procedure" on page 10).
3 INTENDED USE

7.1 Sensor correct identication and positioning
Two types of layouts are available:
• BASIC SETUP - with a pair of sensors US1 + US2 (Fi g . 5 ).
Fi g . 5
Place the sensors in relation to the boom center C:
US1 (RH side) + US2 (LH side) = external pair of sensors (far from boom center), at a distance from boom end corresponding
approximately to 30% of the half-boom length.
• COMPLETE SETUP - with two pairs of sensors US1 + US2 and US3 + US4 (F i g. 6 ).
Fi g . 6
Place the sensors in relation to the boom center C:
US1 (RH side) + US2 (LH side) = external pair of sensors (far from boom center), refer to basic setup.
US3 + US4 = internal pair of sensors (the ones closest to boom center), at a distance from boom center corresponding to
approximately 30% of the half-boom length.
Install the US1 / US3 sensors on the LH side of the boom and the US2 / US4 sensors on the RH side (rear view of the tractor).
The conguration with two pairs of sensors is to be preferred: in case of very large booms, it allows creating an average of the
distances of sensors from ground unevennesses.
Furthermore, the sensitive surface of the sensors must be positioned ALWAYS HIGHER than nozzle outlet (LV > 0 mm, F i g. 7 ).

7.2 Sensor optimal orientation
Fi g . 8
• Lateral inclination (internal)
Sensors must be oriented towards the nearest side of the tractor;
an inclination of 5° is recommended and useful to compensate the gradient of the boom
due to the BLC system correction.
Fi g . 9
• Forward inclination / height
As the ultrasound emission of the sensor has a conical shape with an amplitude of
approx. 15°, advance the sensors by 15° with respect to the tractor travel direction.
This inclination allows avoiding interferences with the cone outlet of the liquid sprayed
by the nozzles.
To optimize the sensor measuring capacity it might be also useful to move the sensor
position forward (always in relation to the travel direction) and / or increase their height
with respect to the nozzle outlet.
ALWAYS avoid the range of action of the sensor to superimpose the spraying cone.
Fi g . 10
• Minimum distance between the sensors
If the sensors are too close to one another ultrasound superimpositions may occur
causing system errors: respect the minimum distance of 2.5 m.
It is the installer responsibility to check that the measurements detected by the sensors are correct and to avoid possible
interferences with the cone outlet of the liquid sprayed by the nozzles.

INSTALLATION
8 WIRING CONNECTIONS
• Use original ARAG harnesses only.
• Take care not to break, pull, tear or cut the cables.
• Use of unsuitable cables not provided by ARAG automatically voids the warranty.
• ARAG is not liable for any damage to the equipment, persons or animals caused by failure to observe the above instructions.
8.1 General precautions for a correct harness position
• Securing the cables:
- secure the harness so that it does not interfere with moving parts;
- route the harnesses so that they cannot be damaged or broken by machine movements or twisting.
• Routing the cables to protect against water inltrations:
- the cable branches must ALWAYS be facing down.
• Fitting the cables to the connection points:
- Do not force the connectors by pushing too hard or bending them: the contacts may be damaged and system operation may be compromised.
Use ONLY the cables and accessories indicated in the ARAG catalog, having technical features suitable for the use to be made
of them.

This menu allows entering the boom dynamic characteristics.
All parameters are explained in detail in the following pages.
The values must be detected directly on the machine because strictly linked to the hydraulic / mechanical system of the
machine.
DURING MEASURING PROCEDURES, MOVE THE BOOM ALONG THE MAXIMUM ALLOWABLE DISTANCE, COMPATIBLY WITH
THE MACHINE MECHANICAL CHARACTERISTICS AND DIMENSIONS.
Height aggressiveness - BOOM HEIGHT CONTROL AGGRESSIVENESS
It adjusts the power applied by the BLC control to lift / lower the boom.
The easiest way to adjust the aggressiveness value is to check for the presence of swingings during boom movement - from maximum to minimum height.
Too high or too low values make the control unstable and cause vibrations; adjust the aggressiveness value until reaching a smooth implement control
without jerks.
Carry out this procedure with the BOOM COMPLETELY OPEN:
1Check that the boom is perfectly horizontal to the ground.
2 Set the spraying height to the minimum value (Spraying boom height menu, par. 12.1.2 on page 14 ).
3Bring the rotation speed of the power take-off to the typical operating value.
4Disable the BLC control: activate the MANUAL mode (par. 14.2).
5Set an aggressiveness value (Fig. 29).
6Bring the boom to the maximum height (activate the lifting switch on the hydraulic control panel / VT / Joystick).
7Enable the BLC control: activate the AUTOMATIC mode (par. 14.2).
The boom will move automatically to reach the spraying height:
• If boom movement is too slow and with jerks, the aggressiveness level is too low.
Repeat the procedure from point 4, increasing the value.
• If the boom moves too quickly and swinging the aggressiveness level is too high.
As before, repeat the procedure from point 4, decreasing the value.
The ideal adjustment is obtained when boom movement is smooth, without jerks.

Tilt aggressiveness - BOOM LEVELING CONTROL AGGRESSIVENESS
It adjusts the power applied by the BLC control to rotate the boom.
The easiest way to adjust the aggressiveness value is to check for swingings during boom rotation.
Too high or too low values make the control unstable and cause vibrations; adjust the aggressiveness value until reaching a smooth implement control
without jerks.
Carry out this procedure with the BOOM COMPLETELY OPEN:
1 Set the boom rotation center Cto maximum height.
2Bring the rotation speed of the power take-off to the typical operating value.
3Disable the BLC control: activate the MANUAL mode (par. 14.2).
4Set an aggressiveness value (Fig. 29).
5Bring the boom LH end to the minimum height (activate the lifting switch on the hydraulic control panel / VT / Joystick).
6Enable the BLC control: activate the AUTOMATIC mode (par. 14.2).
The boom will rotate automatically to reach the horizontal position:
• If boom movement is too slow and with jerks, the aggressiveness level is too low.
Repeat the procedure from point 3, increasing the value.
• If the boom moves too quickly and swinging the aggressiveness level is too high.
As before, repeat the procedure from point 3, decreasing the value.
The ideal adjustment is obtained when boom movement is smooth, without jerks.
The Tilt aggressiveness parameter works in combination with the following Tilt speed damping parameter:
if aggressiveness setup is not as desired, increase the gain and repeat the adjustment.
Height error gain - PROPORTIONAL GAIN ON BOOM HEIGHT CONTROL
This parameter works in combination with the aggressiveness of the boom height control.
It reduces the error between the set spraying height and the one effectively reached with the BLC system.
Before entering the gain factor, set the aggressiveness (menu Height aggressiveness par. 12.1.5 on page 17).
The easiest way to determine the value is to check the boom height after the BLC system has completed the correction; adjust the gain, if necessary.
Carry out this procedure with the BOOM COMPLETELY OPEN:
1Check that the boom is perfectly horizontal to the ground.
2 Set the spraying height to the minimum value (Spraying boom height menu, par. 12.1.2 on page 14 ).
3Bring the rotation speed of the power take-off to the typical operating value.
4Disable the BLC control: activate the MANUAL mode (par. 14.2).
5Bring the boom to the maximum height (activate the lifting switch on the hydraulic control panel / VT / Joystick).
6Set a gain value (Fig. 29).
7Enable the BLC control: activate the AUTOMATIC mode (par. 14.2).
The boom will move automatically to reach the spraying height.
Check the height reached:
• If the boom has exceeded the set height, repeat the procedure from point 4, decreasing the value.
• If the boom has not reached the set height, repeat the procedure from point 4, increasing the value.
Now, if the boom lifting control exceeds the set height, lower the aggressiveness and repeat the procedure relevant to the gain.
Tilt speed damping: - DAMPING ON BOOM ROTATION CONTROL
This parameter works in combination with the aggressiveness of the boom leveling control.
It allows the BLC system to rotate the boom without swingings or position errors.
Before entering the damping factor, set the aggressiveness (menu Tilt aggressiveness Fig. 29):
if the setup of Tilt aggressiveness is not carried out properly increase the value (Fig. 29).

15.1 BLC - OPERATION
15.2 Fixed geometry
The BLC control considers the boom as a single body: it is then a xed geometry control as the division at boom section is negligible. The boom
must be COMPLETELY open.
To the keep the boom in the desired position, the BLC control performs two types of independent corrections at the same time:
• Boom leveling
The boom rotates with respect to the center (Cin Fig. 34) of the mechanical arm, leveling the inclination with respect to the crop.
1Counter-clockwise rotation (orange - CCW),
2Clockwise rotation (yellow - CW),
• Boom height control
The boom moves vertically controlling the height ( L, C and Rin Fig. 34) with respect to the crop.
3Lifting (blue - UP)
4Lowering (light blue - DOWN),
The ultrasonic sensors (US1÷US4 in Fig. 34) installed on the boom provide the data required for the correction, determining the distances
L/ C/ Rfrom boom to crop.
Fig. 34
WARNING
• Ultrasonic sensors do not distinguish between crop and soil as they detect the rst object encountered.
Boom height is the distance between the arm and the crop (when present).
• The boom, during leveling, rotates with respect to the boom instantaneous center of rotation (CPOINT).
15.3 Hydraulic control
Thanks to the IBX100 hydraulic control unit the BLC control automatically activates:
• the leveling and boom height control hydraulic functions
• system hydraulic drain valve (pilot valve)
Check that the hydraulic system and the valves are connected to the IBX100 hydraulic control unit.
WARNING: DURING AUTOMATIC LEVELING, THE SYSTEM ACTIVATES THE PILOT VALVE, HENCE THE HYDRAULIC CIRCUIT IS
PRESSURIZED.
OTHER HYDRAULIC FUNCTIONS (MOVEMENTS, DRIVES, ETC...) CONNECTED TO THE SAME SYSTEM CAN BE ACTIVATED BY
SENDING THE CONTROL ONLY TO THE SUITABLE VALVE, SINCE THE PILOT VALVE IS ALREADY ACTIVATED BY THE BLC. MAKE
SURE THAT THIS DOES NOT JEOPARDIZE MACHINE SAFETY.
