About the job computer
Job computer functions
The SPRAYER-Controller MIDI 3.0 and MAXI 3.0 job computers are ISOBUS job computers that can
control the operation of field sprayers.
The ISOBUS job computer is the control central of the sprayer. Several sensors are connected to the
job computer, which monitor important implement parts. The job computer controls the implement
based on these signals and on the operator's specifications. An ISOBUS terminal serves as an
interface. All implement-specific data is stored in the job computer and is therefore maintained even
when changing the terminal.
System Overview
Depending on which job computer is used as the base computer for the main system, and which
additional components are installed, the overall system can have different sizes.

Instructions for safe installation
To prevent damage to the system components, consider the following during installation:
▪ Install the job computer where it is protected from dirt. You therefore avoid unintentional cleaning
of the job computer by the implement operator using a high-pressure cleaner.
▪ In the installed position, the connectors and the pressure compensation membrane must be
facing to the side.
▪ Fasten the job computer with four fixing bolts and a flat washer (lock washers can cause cracks
in the plastic on the long term) on a conducting spot on the implement chassis. In case of
improper installation, the ESD discharges can cause malfunctions.
▪ All of the sockets and connectors that are not used must be protected from dust and water using
suitable dummy connectors.
▪ All of the connectors must be tightly sealed. This makes them waterproof.
▪ Do not use the system if some of its parts are damaged. Damaged parts can cause malfunctions
and lead to injuries. Replace damaged components or repair them if possible.
▪ Use only original components manufactured by Müller-Elektronik.
Connecting the AMP connectors
This is how to connect two AMP connectors:
1. Pull out the red locking device of the AMP socket all the way to the end.
⇨ You will hear a loud clicking sound.
⇨ The openings for inserting the locking pins of the connector are visible.
2. Insert the connector into the socket. It should be possible to easily insert the locking pins in the
openings.
⇨ The connector is loosely inserted in the socket.
3. Press in the red locking device.
⇨ You will hear a loud clicking sound.
⇨ A part of the locking device comes through to the other side of the socket.

Procedure
⇨ You have connected and locked the connector with the socket.
Separating the AMP connectors
This is how to separate two AMP connectors:
1. Press in both ends of the red locking device in direction of the connector.
⇨ You will hear a loud clicking sound.
⇨ The locking device has been released.
2. Pull out the red locking device of the AMP socket all the way to the end.
3. Pull the connector out of the socket.
Connecting the job computer to the ISOBUS
To connect the job computer to the power supply and to the ISOBUS terminal, you have to connect
the ISOBUS cable to an ISOBUS power socket on the tractor.
This is how to connect the job computer to the ISOBUS:
1. Take the ISOBUS cable from the job computer.
2. Unscrew the dust protection cap.
⇨
3. Insert the ISOBUS connector into the ISOBUS power socket on the tractor.
4. Lock the connector. For basic vehicle harnesses from Müller-Elektronik, turn the connector
clockwise. For other ISOBUS basic vehicle harnesses, the procedure depends on the model.
⇨ The connector fits tightly.
5. Screw the dust protection cap of the connector and the socket together.

Installing the junction box
Take note of the following when selecting the installation location:
▪ Ensure that cables cannot be damaged by the moving implement.
▪ The cable glands must be facing downwards.
Connecting the sensors and actuators to the junction box
Every sensor and every actuator that is mentioned in the pin-out diagram must be connected to the
junction box mentioned in the pin-out diagram.
This can be done in two ways:
▪ The sensor or actuator ends with a short cable and an AMP connector.
In this case, you will receive a fitting extension cable for each sensor. You must insert the
extension cable in the junction box and connect it to the fitting terminal.
▪ The sensor or actuator ends with a long cable without a connector. You have to insert it in the
junction box and connect it to the fitting terminal.
The terminal to which you must connect the cable core depends on the respective implement and on
the type of sensor or actuator.
Please note that the cable cores for the ultrasonic sensor trigger always need to be connected to Pins
2 and 3.
1. Remove the cable coating so that all cable cores are exposed.
2. Insert the cable to the end of the coat. There should only be cable cores inside the junction box.
The cable coating must end at the junction box casing. This is the only way to ensure that you
have enough space in the junction box to be able to guide all of the cable cores to the terminals.
3. Remove the cable coating of the cable cores ca. 1 cm from the end of the cable core.

Procedure
4. CAUTION! Pay attention to the proper polarity of the cable cores and the terminals.
5. Connect the cable cores to the terminals.
To do so, use the information on the lid of the junction box, on the relay circuit board and in the
pin-out diagram.
6. With screw terminals, use wire end sleeves. Wire end sleeves may not be used with spring-
loaded terminal blocks.
7. Close the screw connections of the junction box.
After screwing them shut, the glands should be sealed.
8. Close unused openings in the casing of the junction box with blind caps.
Inserting the cable core into a terminal
There is at least one terminal block with three rows of terminals in the junction box.
Each terminal consists of two openings:
▪ The upper opening of the terminal opens, among other things, the lower opening.
▪ The bottom opening of the terminal serves to insert and clamp one cable core.
You have prepared a small flat screwdriver that fits the upper opening of the terminal. You only
need this screwdriver if there are wire end sleeves on the cable cores.
You have cut the cable to the proper length and have exposed the cable cores according to the
instructions, or you have a finished cable from Müller Elektronik.
The tractor engine is switched off.
The junction box is not powered.
There is no voltage on the components to be connected.
1. Find the proper connectors for the cable cores to be connected.
To do so, use the information on the lid of the junction box, on the relay circuit board and in the
pin-out diagram.
2. Insert the cable core into the opening in the lower part of the terminal. If you use wire end
sleeves, you first have to use the screwdriver.
⇨ You hear the cable core click into place.
⇨ The cable core will be held by the terminal.
⇨ You have clamped the cable core.
Connecting the junction box to the job computer
1. Connect the AMP connector of the junction box onto the proper job computer.

Switching on the job computer
1. Connect the ISOBUS cable of the job computer to the ISOBUS connector on the tractor.
2. Start the ISOBUS terminal.
⇨ The job computer is started together with the terminal.
⇨ When starting up for the first time, the job computer initially has to transmit lots of
information to the terminal. This can take a few minutes.
⇨ When all of the data from the job computer application has been loaded, their icon appears
on the terminal: .
3. Open the job computer application. To do so, follow the instruction for the ISOBUS terminal.
⇨ The work screen of the job computer appears.
Layout of work screen
The work screen is always shown during work and informs you of the status of the field sprayer.
The work screen is divided into several areas. In each area, information on specific topics may
appear.
With the configuration of the job computer, the areas can be changed by the field sprayer
manufacturer for a specific field sprayer model. For this reason, the following graphs only show the
standard version of the overview.
Areas on the work screen
You can read about the information that appears in these areas in the following sections.
Function icons on the work screen
Function icons appear beside the work screen, which perform functions when they are tapped. Their
position and operation depend on the type of ISOBUS terminal.
In the table below, you can see the meaning of the function icons on the work screen.
