1 Introduction

The SPRAYDOS board computer is a new development on the basis of the well tried and tested SPRAY-Control board computer. The SPRAYDOS has up to 9 boom section switches with a main switch, the manual or automatic regulation of the spray rate and up to 4 hydraulic functions (the long version allows a further 10 hydraulic functions as soon as foam marker and corner nozzles). The current speed and the current spray rate are displayed simultaneously.

If an automatic pressure sensor is installed, the pressure is displayed instead of the speed. The speed appears on the display when the km/h key is pressed for about 5 seconds. Specific applications can be carried out by pressing the +/- 10% key. The pre-set rate resets by means of the l/ha key. The spray rate is adhered to accurately even when the speed varies.

WARNING

This signal word identifies medium-risk hazards, which could potentially cause death or serious physical injury, if not avoided.

CAUTION

This signal word identifies low-risk hazards, which could potentially cause minor or moderate physical injury or damage to property, if not avoided.

CAUTION

If the SPRAYDOS is being used on a trailed field sprayer, no speed sensor is to be connected to the SPRAYDOS. In this case the speed is measured at the wheel of the field sprayer.

CAUTION

During transport the SPRAYDOS must be switched off.

If available, the drawbar or axle steering must be set to centre position during transport.

4.2 System description

The SPRAYDOS can be installed on the field sprayer as a fully automatic control instrument. The device carries out an area-related control of the spray rate regardless of the current speed, the working width and the pre-set rate.

The calculation of the current spray rate, speed, working area, total area, quantity spray as well as the total quantity and the working time is carried out continuously.

The device consists of the computer [1] and the console [2-5].

A wheel/cardan speed sensor [9] can be connected directly to SPRAYDOS in order to determine the speed.

The SPRAYDOS can be connected directly to the signal socket [10] on the tractor using a connecting cable. By means of a switch integrated in the connecting cable it is possible to switch between wheel/cardan and a radar device.

The field sprayer is connected by means of the machine plug (circulation, hydraulic) on the SPRAYDOS.

5.3 Sensor X (calculation of the distance)

Mounting on four-wheel drive tractors:

Mount the hose clamp with a magnet to the cardan shaft.

The sensor must point in the direction of the magnets at a distance between 5 – 10 mm. It is to be mounted vibration-free.

Mounting on tractors without without four-wheel drive:

Install the magnets in the wheel shell using V4A screws provided, distributing them evenly over the circumference.

The number of magnets depends on the size of the wheel.

The distance travelled from impulse to impulse must not exceed 60 cm.

Calculation:

Wheel circumference ÷ 60 cm = number of magnets

e.g.: 256 cm ÷ 60 cm = 4.27 = min. 5 magnets

Mount the sensor to the steering knuckle using the bracket provided so that the end of the sensors is pointing towards the magnets. The distance should be 5-10mm

Mounting on the wheel of the trailed sprayer

Mount the sensor on the wheel of the field sprayer in the same way as on the wheel of the tractor (see diagram 5.2). In this case the electrical connection is in the machine distributor manifold.

5.4 Adapter cable for tractors with signal socket

In this case it is not necessary to install the X sensor. The SPRAYDOS is connected to the tractor's signal socket using the adapter cable [10].

> Press to transfer the new value

6.2.3 "Number of boom sections" key

This key is used to enter the number of boom sections (max. 9) and the number of nozzles for each boom section.

The boom sections are numbered from left to right as seen from the direction of driving.

During input, the boom sections are displayed on the left hand side and the number of nozzles on the left hand side.

Procedure:

> Press

on the left a 1 (boom section 1) is displayed and on the right the number of nozzles.

> To alter the number of nozzles, enter the new value using the keys and . > Press

the value is now stored in the memory. On the left hand side of the display a 2 (boom section 2) appears. If the

value – number of nozzles – on the right hand side of the display is correct, press to transfer the value and select boom section 3. This process can be carried on until the 9th boom section is reached. Subsequently the total number of boom sections and nozzles will be displayed.

> If e.g. the field sprayer has 5 boom sections, enter a 0 when the 6

sets the boom sections 7-9 automatically to 0. In this case the computer operates on the basis of 5 boom sections and displays the number of boom sections and the total number of nozzles as 5:30.

boom section is displayed. The computer then

6.2.4 "Pre-set rate - l/ha" key

The required spray rate is communicated to the computer using this key. If the switch is in automatic position the electronics control the pressure and subsequently the spray rate automatically.

If, due to a fault (e.g. tank empty) the pre-set rate is not achieved, an alarm is set off.

Input value

> Press > Enter the value using the keys and

> Press to transfer the new value

The value entered is controlled by pressing again.

6.2.5 "Impulses / litre" key

Direct input of impulses per litre or a calibration of the flow meter can be carried out here. The various possibilities are described in the chapters 6.2.5.1 - 6.2.5.3.

6.2.5.1 Impulses per litre input

If the number of flow meter impulses per litre is known, the value can be entered directly.

1. The value impulses/litre is known:

> Press > Enter the value using the keys and > Press to transfer the new value

6.2.5.2 Tank method

With the tank method calibration is carried out by weighing the entire field sprayer before and after spraying. The procedure is as follows:

> Fill the tank with water and determine the quantity (weigh). > Press and simultaneously

> While stationary, switch on the field sprayer using and spray a few hundred litres.

(The computer now counts the flow meter impulses). All sections must be open.

> Switch off the sprayer using > Determine the amount sprayed (reweigh).

> Set the value using the keys and > Press to transfer the new value

> The computer calculates the "impulses / litres"

The flow meter impulse number should be checked several times a year especially before each season.

6.2.5.3 Nozzle method

6.2.6 "Type" key

This key is used to enter 2 functions. The number before the comma determines the manifold type. The 2 positions after the comma determine the control constant.

> Press > Set the value using the keys and > Press to transfer the new value

6.2.6.1 Manifold type

The manifold type is communicated to the computer via the number before the comma.

The following manifold types are taken into account (in the example a control constant of 15 is assumed):

CAUTION

The valves on the balanced pressure manifold must be set accurately.

Balanced pressure manifold without reflux measurement

The manifold is equipped with electrovalves and separate balanced pressure valves (e.g. Tecnoma-Elektra). The spraying fluid which flows back to the tank via the balanced pressure valves when the boom section is switched off is not recorded by the flow meter.

Manifold without balanced pressure function

The manifold is equipped with motor or electromagnetic valves.

Only the quantity sprayed via the spray bar is measured by the flow meter even when the boom section is switched off.

If, at the end of the field with the sprayer switched off, one or more boom sections are switched off, the computer takes a pre-setting via the control valve. Fine-tuning then takes place once the field sprayer has been switched on.

Balanced pressure manifold with reflux measurement

The manifold can be equipped with either motor or electromagnetic valves. When boom sections are switched off the flow meter also measures the amount which flows back to the tank. The computer takes this into account when calculating the quantity sprayed depending on the number of nozzles per boom section.

Example: Field sprayer with 5 boom sections

One boom section is switched off; only 4/5 of the total quantity is recorded (1/5 flows back into the tank).

Spraying devices without balanced pressure function

This setting takes into account the specific features of spraying devices for use in fruit, wine and hops production. In this case the quantity and not the working width is altered when the upper nozzle segments are switched off. If one side of the device is completely switched off, the working width is halved.

6.2.6.2 Control constants

Depending on the fabrication and the size of the sprayer different control times are required when there is a certain deviation from the pre-set value.

The computer calculates the control time with which the control valve is driven. The control time is determined by the control constant.

> Regulation too sluggish -> enter a highter value > Regulation overdrive -> enter a lower value

The control constant is optimally selected, when, in the case of a deviation from the pre-set value, one control process is sufficient for the computer to get to the proximity of the pre-set value and then fine tune by means of a few small processes.

Regulation can be seen in the display l/ha.

Control constants can be within the range of 1 to 99.

See also 6.2.6.1 "Manifold types".

6.4.2 Manual/automatic switch

This switch can be used to switch between automatic and manual operation. In "Auto" position the computer controls the spray rate automatically. If the switch is set at "Manual" the correct spraying pressure must be set manually by means of

the key.

6.4.3 Spraying pressure +/- key

This key is for manual adjustment of the spraying pressure in manual operation mode. Manual operation is selected by

means of the switch.

6.4.4 Boom section switch

The function of the boom section switch is to switch the individual boom sections. If a switch is off, then the corresponding

boom section is also switched off and cannot be switched on by means of the boom section main switch .

6.4.5 Configuring the section switches

If you connect a Spraydos with nine section switches to a sprayer with five sections, you can set that only every second switch is used. In doing so, please note that the LEDs above unused switches are also illuminated as soon as they are switched up.

Diagram 6-2 Section switches

On the left: Every second switch controls one valve (Configuration 1:0); on the right, the first five switches control the valves (Configuration 1:1)

> Reboot the computer. > Press the and keys (in this sequence) simultaneously.

> The current configuration appears on the display:

> Set the value using the and keys. > Press the key to adopt the new value.

> Reboot the computer.

6.5 Hydraulic functions switch

6.5.1 Short SPRAYDOS version

The short SPRAYDOS version supports a maximum of 4 hydraulic functions. For this purpose up to 4 switches can be mounted on the top right-hand area of the computer. The function of each of these switches is illustrated by the pictograms on the tactile keyboard.

6.5.2 Long SPRAYDOS version

The long SPRAYDOS version has an additional row of switches underneath the section switches. Here, up to 10 hydraulic functions as well as foam markers and corner nozzles can be accommodated. Pictograms illustrate their function.

6.6 Operating procedure

Once the machine data have been entered (6.2.1- 6.2.6), only the start function (6.3.1) has to be activated before operation can begin. During operation all values can be called up.

CAUTION

Before initial operation fill the sprayer with water (without spraying fluid). Start the field sprayer. Subsequently check the values measured and displayed.

Magnet

The calibration mode is activated by applying a magnet onto the casing. The magnet must be positioned exactly above the left edge of the display.

LED

Is switched off in calibration mode, and flashes to indicate completion. The same LED is used for all of the calibrations.

The automatic mode guarantees accurate dosage. Please ensure that the pressure in connection with the drop formation for the nozzle type in operation is maintained.

At times when the field sprayer is switched on and off, the same speed should be driven if possible to avoid brief underdosage or over-dosage after switching on the field sprayer.

If regulation is to be carried out manually, set the switch to manual. The quantity is controlled using the key.

Once the job is completed all values can be called up. A new job begins with the "start function" (6.3.1).

6.7 Calibrating hydraulic functions

If the following hydraulic functions are available, they can be calibrated by the user:

> Boom control > Drawbar steering

Calibration serves to adapt the controller to the characteristics of the implement.

- Control dial to the left

The implement component (boom/drawbar) will be moved to the left, until it reaches a resistance (ground/stop).

- Control dial to the right

The implement component (boom/drawbar) will be moved to the right, until it reaches a resistance (ground/stop).

- Control dial at the centre

The implement component is not moved.

6.7.1 Activating calibration mode

> Apply the magnet onto the casing, as shown in the figure above.

 The LED is illuminated.

> -Within one second, turn the control dial or first 90°

to the left, then 90° to the right and then back to the centre.

 The LED flashes several times. If the LED does not flash, it means that the computer was not put into

calibration mode and that you must repeat the steps.

 The LED is turned off. > Leave the magnet on the casing until the calibration is completed, unless you are prompted to lift it briefly. > If you remove the magnet prematurely for longer than 1 second, the LED flashes briefly. The calibration will be

cancelled and the values determined during calibration are discarded.

In calibration mode, the control dials are used differently than normally:

6.7.2 Calibrating the boom control

Use the control dial for the calibration.

To calibrate the boom control:

> Activate calibration mode. See: p. 25 > First, you must teach the computer the direction in which the control dial must be turned to slope the boom to the

right. This direction depends on the electrical connection of the actuators. To do so, follow the next two steps.

> or - Slope the boom a few degrees to the right. It does not have to be sloped down to the

ground.

 The boom was sloped a little to the right. > Lift the magnet briefly and apply it again.

 The LED flashes briefly.

 You have taught the computer where the right side is.

> - Move the boom into a horizontal position.

 The boom is horizontal.

> - Turn the control dial to the centre position. > Lift the magnet briefly and apply it again.

 The LED flashes briefly.

 You have calibrated the horizontal position.

> - Slope the boom as far as possible to the right.

 The boom touches the ground on the right.

> - Turn the control dial to the centre position. > Lift the magnet and apply it again.

 The LED flashes briefly.

 You have calibrated the slope to the right.
