Product description
Basic principles of the EDS single nozzle switching system
The single nozzle switching system [also called EDS] is a system that serves to directly open and
close each nozzle on a field sprayer.
This makes it possible to reduce the number of overlaps more effectively than with conventional
systems, which can only open and close entire sections.
The system obtains all of the required information from the job computer of the field sprayer and the
SECTION-Control application. This gives the driver the ability to either control the nozzles manually,
or allow them to be controlled by the software.

computer and sends commands to the EDS modules.
EDS-BUS
EDS-BUS is a data line from the EDS communication module to all of the EDS modules.
The EDS communication module is connected with two EDS modules at the middle of the boom.
Other modules are connected to this module in a chain.

EDS Module
An EDS module is a microprocessor that opens or closes the feed line to a nozzle.
The EDS modules described in these operating instructions work with air pressure. They are also
called pneumatic EDS modules or EDS-P modules.
EDS modules differ in terms of:
▪the diameter of the quick connectors
▪the type of the multiple nozzle holders that they can control
▪the item number
Pneumatic EDS module (or EDS-P module). The following labels can be found on the module casing
Output (OUT) and input (IN) of the EDS Bus

Diameter: 4mm or 6mm, depending on the
model
Openings for the U-bracket
Quick connector for pneumatic output B
The pneumatic outputs C and D are located
on the opposite side.
Slot for the spray agent pipe
Rating plate
Quick connector for the pneumatic line (main

Diameter: 8mm
Nozzle holders
The system can work with the following types of nozzle holders:
▪Single nozzle holders
▪Double nozzle holders - multiple nozzle holder with two nozzles.
–Prerequisite: ISOBUS job computer manufactured by Müller-Elektronik with a licence for
VarioSelect nozzle holders.
▪Quadruple nozzle holders - multiple nozzle holder with four nozzles.
–Prerequisite: ISOBUS job computer manufactured by Müller-Elektronik with a licence for
VarioSelect nozzle holders.
The more nozzle holders are connected to an EDS module, the longer the required connection cables
for the EDS modules. For this reason, there is a different EDS module for each type of nozzle holder.

Installation
Install the EDS communication module
The EDS communication module must be firmly installed on the field sprayer.
The place of installation must be selected such that the ISOBUS job computer and the EDS modules
can be connected later on.
Installing the EDS modules
You should bear the following in mind when installing the EDS modules:
▪Install the EDS modules on the field sprayer boom, close to the nozzle holders.
▪To attach the EDS modules, you can use e.g. the universal bracket in the form of a U-bolt (M5).
▪The position of the EDS module is irrelevant. It is only important that all of the nozzle holders can
be easily reached with the hoses.
▪Pneumatic valves must be connected to the nozzles in a specific sequence.
▪The plugs must be connected to the nozzles in a specific sequence.
▪On field sprayers with more than 72 EDS modules, additional power must be supplied to the
outer half of the EDS modules on each boom side. The following cable harnesses are used for
this purpose: 3030308340 and 3030308341
Preventing leaks
Observe the following instructions to prevent leaks in the system:
▪Protect the pneumatic connections and plug contacts of the EDS modules from humidity and
dust. The pneumatic connections must be clean both during installation and also during transport
and storage. Dirty connections can cause leaks.
▪Only use pneumatic hoses made of hard plastic like polyamide (PA). Soft hoses, e.g. made of
polyurethane (PU) or polyethylene (PE), can cause leaks in the connection area of the EDS
module.
▪Do not paint the EDS modules.

Planing the sequence
The sequence in which you must connect the nozzles to the pneumatic valves depends on the nozzle
holders that you are using:
▪Single nozzle holders
–One pneumatic valve per nozzle holder.
–A, B, C, D from left to right.
–If you cannot maintain the sequence on an EDS module and the nozzle holders are
connected in the sequence D, C, B, A, you have to mark this EDS module as "rotated". See:
"EDS" tab
–If the number of nozzles on each side of the boom cannot be divided by four, a few
pneumatic valves are left over. These must always be the pneumatic valves located at the
outer ends of the boom.
For example: If 22 nozzles are installed on the left side of the boom, two pneumatic valves
are left over after the installation. They are located at the ends of the boom. On the left side,
pneumatic valve A remains open, and on the right side, pneumatic valve D.
Arrangement of the pneumatic EDS modules on a boom with single nozzle holders
▪Double nozzle holders
–Connect pneumatic valves A, B with the first nozzle holder and pneumatic valves C, D with
the second nozzle holder.
–Pneumatic valve A and pneumatic valve C have to be connected to the same type of nozzle
on all of the nozzle holders, because they are switched simultaneously.
▪Quadruple nozzle holder
–Use one EDS module per nozzle holder.
–Each pneumatic valve must correspond to one nozzle type. This association must be
maintained for all of the nozzle holders.
Connecting the pneumatic line to the EDS modules
Before connecting the EDS modules to the air compressor, make sure that it fulfils the following

Inserting the hose
1. Push the end of the hose into the opening of the quick connector.
⇨The hose will be hooked onto the quick connector and cannot be pulled out.
Pulling out the hose

2. Pull the hose out. The hose can be pulled out very easily when the quick connector was properly
pressed in.
Connecting the cable
Every EDS module has two cables that can be used to connect to other modules and the
communication module. The connected EDS modules thereby form a line. This line is called EDS
BUS.
Connecting the communication module to the EDS modules
The end of each cable from the communication module is marked with a letter:

Allocating the addresses for the EDS modules
For the sprayer job computer to be able to properly switch the pneumatic valves, every EDS module
must have a clear address.
You must allocate the addresses in the following cases:
▪With the first configuration
▪When replacing an EDS module
To allocate the addresses for the EDS modules:
You have properly connected all of the components.
1. Open the start screen of the "EDS" application.
2. - Start the address allocation.
⇨The individual EDS modules are counted during the address allocation.
⇨The EDS modules on the left side of the boom are counted first, then the EDS modules on
the right side of the boom.
⇨The address allocation is finished if there is no error message after it.
Testing the configuration - "Demo" function
Once you have allocated the addresses for the EDS modules, you can test whether all of the nozzles
are switched properly and in the correct sequence.
You can test the nozzles automatically or manually.
This is how to test the nozzles automatically:
1. Open the start screen of the "EDS" application.
2. - Open the “EDS / Manual mode” screen.

3. - Activate the demo function.
⇨The nozzles will be opened successively from left to right.
4. Check if the nozzles are opened in the correct sequence. If not, it is possible that valves were
connected rotated.
5. Or: Use A, B, C, D to switch the desired pneumatic valves.
Configuring the power supply of the EDS modules
If there are problems with the power supply, you can set the voltage with which the valves of the EDS
modules are switched and operated.
The following parameters are used for this purpose:
▪"Switch-on Voltage" (German: Einschaltspannung)
The valves in each EDS module is switched on with this voltage. The optimal value is 9V.
▪"Hold-on Voltage" (German: Haltespannung)
After the switch-on time has expired, the valves will be supplied with this voltage.
▪"Switch-on Time" (German: Einschaltdauer)
After this time following switching, the voltage changes from the "Switch-on Voltage" to the
"Hold-on Voltage".
▪"Group Delay" (German: Gruppenverzögerung)
This parameter describes the delay with which the valves are successively switched.
–As a standard 0
–If the modules do not switch on reliably, you can increase this value to 10 or 20ms.
–Booms with 72 modules (36m working width) require 20ms group delay.

A description of this parameter can be found in the TRACK-Leader operating instructions.
Configure the following parameters in the geometry of the job computer application:
▪"Delay on start" and "Delay on stop"
Because the field sprayer does not have any section valves and the nozzles cannot be directly
controlled, the standard value is not current.
1. On the work screen, press:
