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.

EDS communication module
The EDS communication module controls the EDS modules. It receives signals from the ISOBUS job
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
line
Quick connector for pneumatic output A
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
line)
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.
Installation example: EDS-P module installed directly over a quadruple nozzle holder
