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.
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.
2 Safety instructions
2.1 Intended use
The SPRAYDOS is specified exclusively for agricultural use and in wine, fruit and hop growing. The manufacturer
takes no responsibility for any installation or application outwith this area.
The manufacturer does not accept liability for damage to persons or property resulting from unspecified use. In
such cases all risks are the responsibility of the user.
Specified implementation also includes adhering to the operation and maintenance requirements stipulated by the
manufacturer.
Relevant accident prevention regulations as well as other generally recognised safety, industrial, health and road
traffic rules are to be adhered to. In addition the manufacturer accepts no liability in cases where arbitrary
modifications have been made to the device.
2.2 Basic safety instructions
Observe the following recommended precautions and safety instructions:
Do not remove any safety devices or labels.
Before using the SPRAYDOS read and understand this guide. It is of equal importance that others operating this
device also read und understand the manual.
During maintenance or when using a battery charger, switch off the power supply.
Never service or repair the device while the job computer is switched on.
Before welding on the tractor or on an attached machine, interrupt the power supply to the SPRAYDOS.
Only use a soft damp cloth with clear water or a little glass cleaning agent to clean the SPRAYDOS.
Operate the keys with your finger tips but avoid using fingernails.
Should any part of this guide remain incomprehensible after reading, contact the dealer or Mueller-Elektronik
Service for further clarification before using the SPRAYDOS.
Read carefully all safety instructions in the manual.
Learn how to operate the SPRAYDOS correctly. Nobody is to operate the machine without exact instructions.
Keep the SPRAYDOS and the spare parts in good condition. Unspecified alterations can impair the function and/or
safety and affect the life span of the machine.
2.3 Layout and meaning of warnings
All safety instructions found in these Operating Instructions are composed in accordance with the following pattern:
This signal word identifies actions which could lead to operational malfunctions if performed
incorrectly.
These actions require that you operate in a precise and cautious manner in order to produce
optimum work results.
2.4 Safety notice for the subsequent installation of electrical and electronic devices
and /or components
Present-day agricultural machines are equipped with electronic components and devices, whose function can be affected
by electromagnetic emission from other devices. These influences can lead to endangerment for individuals when the
following safety measures are not adhered to.
When subsequently installing electrical and electronic devices and/or components in a machine with a connection to the
electrical system, the user must take sole responsibility for testing the installation for interference of the vehicle electronics
or other components. This applies in particular to the electronic controls of:
EHR
Front lifting gear
Power take-off shafts
Motor
Gears
Above all it must be ensured that all subsequently installed electrical and electronic components comply with the current
version of the EMC directive 89/336/EWG and carry the CE symbol.
In addition the following requirements must be fulfilled when upgrading with mobile communication systems (e.g. radio,
telephone):
Only approved devices complying to national regulations (e.g. BZT approval in Germany) are to be installed;
The device must be securely installed;
The use of portable or mobile devices inside the vehicle is permissible only via a connection to a permanently
installed outside antenna;
The transmitting unit is to be installed in a position away from the vehicle electronics;
An antenna should only be installed professionally ensuring that there is a good earth connection between the
antenna and the vehicle chassis.
Please refer to the manufacturer's installation instructions for cabling and installation as well as the maximum current
consumption.
