1.10 Description of function
The Vento® is a pneumatic granulate doser for applying seeds and granulated fertiliser in agriculture.
Precise dosing is achieved using a rotary feeder valve that is driven according to the speed of the vehicle. Auto-
matic dosing by means of a wheel sensor or GPS receiver is possible. The spreader has an agitator for spreading
materials with reduced free-flowing properties. The spreading material is applied by means of an airflow through 8
hoses.

Mounting and start-up
8 / 52 1.0 Vento®
2 Mounting and start-up
Warning!
Risk of injury due to inadequate attachment
If the spreader or hopper tip over, this can cause crushing or other injuries.
•Only mount the spreader on carrier vehicles that have a sufficient load carrying capability.
•Before start-up, make sure that the implement, spreading material hopper and hopper cover have
been correctly attached.
2.1 Implement holder
The Vento® is supplied mounted on the universal holder
as standard. The mounting is specifically dependent up-
on the carrier vehicle provided, and must be adapted to
its conditions.
Before operation, check the attachment of the spread-
er on the universal holder. The attachment must be se-
cured with the safety bolts (1). If replacing them, use
M10 bolts with a strength class of at least 8.8, with self-
locking nuts.
Optionally, mounting is possible using U-brackets (2) on
a square tube with dimensions 80×80 mm to 120×120
mm.
2.2 Installing hoses
Advice!
Route hoses with as few bends as possible, and with the largest possible bending radius.
Incorrect hose routing can result in blockages in the hose.
Only insert clean hose grommets into the holder.
Installing hose
1. Screw hose grommet (2) onto hose.
2. Push hose grommet (2) into the holder (1) until it en-
gages.
3. Route the hose and cut to length.
4. Cut the hose off with a straight end.
5. Attach baffle plate (3) to the hose with a hose clip.

Mounting and start-up

2.3 Electrical connection
Caution!
Risk of short-circuit and injury when working on the battery and electrical system!
Electrical current flowing through the body can cause cramps, ventricular fibrillation,
heart stoppage and internal burns. Risk of burns due to arcing caused by short circuits.
•Protect the battery against damage and moisture.
•Disconnect the electrical power supply before starting work on the battery and electrical system.
•Use suitable tools so as to avoid short circuits.
•Sure that the cables are routed without tension, kinking and chafing, and also avoid bending them
around sharp edges.
•During all work on the battery, please comply with the regulations of the vehicle manufacturer in
question.
•Only use original cables, or ones approved by the manufacturer.
•Always push on the cap and lock it to protect electrical connections against damage.
Advice!
Faulty cables or cables with incorrect dimensions can lead to malfunctions and damage to the spread-
er. Any changes to cable or plug connections without factory approval automatically invalidates the entire
warranty.
Changes to cables undertaken by the customer are taken into account in the case of repair. Only use original ca-
bles, or ones approved by the manufacturer. You must consult with the manufacture before carrying out any cable
modifications. Power loss must be taken into account when extending cables. A poor power supply may prevent you
from achieving the desired blower speed. Also, this could lead to intermittent complete failure.

Mounting and start-up
10 / 52 1.0 Vento®
Connect connection (3) with fuse (4) to the positive terminal of the battery. Run the end of the cable with the
socket to the carrier vehicle.
3. Plug the control cable of the spreader into the multi-pin socket of the control panel.
Advice!
To ensure an optimum electrical power supply, use the supplied battery cable.
The spreader is ready for use.
2.4 Filling the Vento®
Warning!
Risk of injury during operation if the spreading material hopper is open, due to spread-
ing material being thrown out and rotating parts.
This can cause injuries to the eyes and crushing injuries.
•Only operate when the hopper cover is closed.
•Always switch off the spreader and blower before opening the spreading material hopper.
Warning!
Risk of injury!
•Wear appropriate working and protective clothing during all work.
•Comply with the regulations of the fertiliser manufacturer.
Advice!
Attach the data sheet of the fertiliser used in a clearly visible position on the spreader.
Advice!
Make sure that no foreign bodies (e.g. packaging material) get into the hopper, in order to avoid malfunc-
tions.

Mounting and start-up
Vento®1.0 11 / 52
Before start-up, make sure that the hopper on the Vento® has been firmly bolted in place. To do this, check the four
knurled screws (1).
Filling
1. Make sure that the spreader and blower are
switched off.
2. To fill the spreader, release the rubber clamping
band (2) on the hopper and remove the cover (3).
3. Make sure that suitable rotary valves are fitted ac-
cording to the spreading material table, and that the
load relief roof of the agitator has been mounted cor-
rectly.
4. Fill the spreading material, making sure that no for-
eign bodies or impurities get into the hopper.
5. Before closing the hopper, make sure that the
seal is in place all round between the hopper
and the hopper cover.
6. Close the hopper with the four rubber clamping
bands (2) making a firm seal.
Warning!
Incorrect filling will lead to incorrect dosing applications.
•The hopper cover must be closed during operation, in order to avoid incorrect dosing applications.

3.4.5 Electronic lifting gear control (EHR) function
The spreader is stopped automatically when the front or rear hydraulics of the carrier vehicle are lifted. The spread-
er can be stopped manually at any time using the control panel.
The signal can be detected by means of a 7-pin plug or a sensor signal.
7-pin socket
1. Connect the connecting cable of the control panel to
the 7-pin signal socket of the carrier vehicle.
2. Set the EHR signal of the carrier vehicle depending
on whether the carrier vehicle sends the hydraulic
signal when lifting or lowering.
Sensor signal
Advice!
Please note that the contact surfaces (1) of the sensor are only located on the left and
right sides.

Operation
16 / 52 1.0 Vento®
1. Mount the sensor in the joint section of the lower link.
2. Mount the magnetic encoder to the lower link.
3. Set the position of the sensor and the magnetic encoder. Maximum distance 8 mm.
Hydraulics lowered:
Sensor is not allowed to be in field of magnetic encoder. Dosing stops (see EHR setting: high active or low active).
Hydraulics lifted:
Sensor must still be in field of magnetic encoder. When the hydraulics are lifted, the sensor must not leave the field
of the magnetic encoder, as otherwise the dosing will start again.
3.4.6 Setting setting signal for electronic lifting gear control (EHR)
The spreader is equipped ex-works with EHR signal communication (socket). The hydraulic signal is taken from the
7-pin EHR socket of the carrier vehicle or from the sensors attached to the lower link (install magnet with sensor on
lower link - option).
Depending on the carrier vehicle, the signal is output on lifting or on lowering. Check the EHR signal is set correctly
and correct it if necessary.

•Working width
•Calibration value of the spreading material
The calibration value can be stored in a spreading table, see Chapter 3.4.8, "Spreading tables and calibration pro-
cedure".
The output rate, working width and product can be set directly, see Chapter 3.4.3, "Changing the settings".
