1Introduction
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.

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.
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.
The field sprayer is connected by means of the machine plug (circulation, hydraulic) on the SPRAYDOS.
CAUTION
During transport the SPRAYDOS must be switched off.
If available, the drawbar or axle steering must be set to centre position during transport.

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.
CAUTION
If an X sensor is connected in the machine distributor, no sensor is to be connected to the
SPRAYDOS.
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].

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
With the nozzle method the quantity sprayed is measured at a nozzle and projected to the total number of nozzles. The
procedure is as follows:
> Fill the tank with water.
> Secure a measuring jug below a nozzle.

Copyright Müller-Elektronik GmbH & Co.KG, Installation and operating instructions SPRAYDOS (07.2016) Page - 19 -
> Press and simultaneously
> While stationary switch on the field sprayer using until the measuring jug has been filled with e.g. 2 litres (the
computer counts the flow meter impulses). All sections must be open.
> Switch off the sprayer using
> Determine the amount sprayed
(read the quantity in the measuring jug and multiply by the number of nozzles)
> Set the value calculated using the keys and
> Press to transfer the new value
> The computer has now calculated the "impulses / litres"
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):
Parameter
Manifold type
0.15
Balanced pressure manifold without reflux measurement
1.15
Manifold without balanced pressure function.
2.15
Balanced pressure manifold with reflux measurement
3.15
Spraying devices without balanced pressure function
Manifold type (number before the comma)

Page - 20 - Copyright Müller-Elektronik GmbH & Co. KG, Installation and operating instructions SPRAYDOS (07.2016)
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).
CAUTION
The valves on the balanced pressure manifold must be set accurately.
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.
