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.

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.

Procedure

⇨

6. When the work is completed, separate the connection and screw the dust protection cap back

on.

⇨

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

4.3.3

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.

“Target Rate” parameter

The quantity entered as the target rate will be applied when the field sprayer is working in automatic mode.

You can configure up to three different target rates, between which you can switch on the work screen.

“Working Width” parameter

Field sprayer working width.

“Wheel Impulses” parameter

Number of impulses the wheel sensor sends to the job computer on a 100m distance. Used to calculate the speed.

The number is determined by the wheel sensor calibration.

“Minimum Pressure” parameter

This setting defines the minimum pressure up to which the spraying pressure is optimal.

If the spraying pressure drops below the defined pressure, an alarm is issued.

If no pressure sensor is installed on your sprayer, you must enter “0” as the value.

“Maximum Pressure” parameter

This setting defines the maximum pressure up to which the spraying pressure is optimal.

If the spraying pressure increase beyond the defined pressure, an alarm is issued.

If no pressure sensor is installed on your sprayer, you must enter “0” as the value.

“Sprayer off Below” parameter

(Minimum working speed)

If the field sprayer falls below the minimum working speed, the following happens: ▪ Application will be switched off automatically.

▪ The work screen displays the icon

When the value is set to 0, this function is deactivated.

“Regulation off Below” parameter

If the field sprayer falls below this speed, the following happens: ▪ The flow will no longer be regulated and the flow remains unchanged. ▪ Manual mode will be activated.

When the value is set to 0, this function is deactivated.

This parameter must be higher or the same as the “Sprayer off below” parameter.

“Regulation Factor” parameter

In Automatic mode, the spray pressure will be adapted to the current speed of the field sprayer. The adjustment should ensure that the volume of spray liquid that is applied is exactly what you defined in the target rate. The regulation factor plays a decisive role here.

The regulation factor adjusts the reaction speed of the regulation: ▪ The higher the regulation factor, the faster the spray pressure is adjusted. ▪ The lower the regulation factor, the more slowly the spray pressure is adjusted.

When setting the regulation factor, you can pay attention to the following: ▪ If, during movement at constant speed, the current application volume jumps around the target

value, you need to reduce the regulation factor. ▪ If, when speed is changing, the application volume does not adjust to the rate quickly enough,

you need to increase the regulation factor.

“Tank Size” parameter

Size of the tank for the spray liquid.

“Tank level alarm” parameter

When the volume of spray mixture in the tank falls below this value, an alarm message appears on the screen.

“Impulses Main Flow” parameter

Number of impulses the flow meter sends to the job computer per one liter of liquid. Used to calculate the application rate.

The number is determined by the flow meter calibration.

“Stirring off Below” parameter

With this parameter, you can set the fill level below which the stirrer should be switched off.

The implement manufacturer (not the user!) can also define whether the stirrer should be switched on automatically when the job computer is started.

“Maximum Wind Speed” parameter

Wind sensor must be installed.

If the maximum wind speed is exceeded, an alarm will be triggered.

“Extremity nozzles set” parameter

The parameter includes two values: ▪ “Current”

Indicates what the maximum pump speed is currently set to. ▪ “Target”

Used to change the maximum pump speed.

To save the current pump speed as the maximum permitted speed:

1. Highlight “Set value” line.

2. Run the pump speed up to the desired value.

⇨ The current pump speed will be shown on the “Set value” line.

3. - Press.

⇨ The pump speed from the “Set value” line appears in the “Current” line. In this way it has

become the maximum permitted pump speed.

“Section Control” parameter

Manner in which the sections are switched on and off. ▪ “Sequential mode” [➙ 46]

This type is intended for normal spraying work. It is also suitable for spraying on wedge-shaped

areas and strips that are narrower than the working width of the field sprayer.

Calibrating the flow meter

Because the number of impulses per liter can change during the lifespan of a flow meter, calibration must be carried out in the following cases: ▪ Prior to initial start-up. ▪ At the start of each season. ▪ When you detect deviations between the quantity actually sprayed and the quantity displayed. ▪ When you have replaced or repaired the flow meter.

There are two ways you can calibrate the flow meter: ▪ The tank method – it is time-consuming, but precise. ▪ The nozzle method – it is not as precise as the tank method, but is less time-consuming.

Calibrating the flow meter with the tank method

With the tank method, a large quantity of water will be applied from the tank over a specific time.

The flow meter measures the impulses during this time.

After the application, you must enter the quantity of water that has been applied.

Selecting and configuring the speed sensor

You must enter the source from which the job computer shall obtain the current speed.

The configuration procedure can differ depending on the speed source.

Selecting the speed source

Supported speed sources: ▪ “Sensor” – Sensors that are installed on the field sprayer and connected to the job computer:

– Examples: Wheel sensor, radar sensor, impulse-transmitting GPS speed sensor

– Configuration: Configure the number of impulses per 100 meters.

▪ “ISOBUS” – Sensors that are installed on the tractor and whose signal is received through the

ISOBUS.

– Examples: GPS receiver, wheel sensor on the tractor, signal socket

– Configuration: For systems without the option of selecting the sensor input, the “Wheel

impulses” parameter must be set to 0.

▪ “Auto” – Some systems enable automatic detection of the speed source.

– Mode of operation: If a speed signal is detected on the ISOBUS, this speed will be used as

a basis. In the case of signal failure, the job computer will take the impulses from the sensor connected to the job computer as a basis for determining the speed.

– Configuration: For systems that have two sensor types, it is recommended to calibrate the

sensor that is connected to the job computer. In other cases, set the “Wheel Impulses”

parameter to 0.

To configure the speed source:

1. On the work screen, press the following keys successively:

Procedure

Permanently switching off a section using a sensor

If a sensor for monitoring the unfolding of boom sections is installed on the boom, sections can be automatically permanently switched off.

This enables the use of a field sprayer with multiple working widths without having to change the configuration each time.

System delay when switching the sections

For SECTION-Control to be able to open and close the section valves precisely, you must determine how many milliseconds are required for the liquid to travel from the valve to the nozzle. Afterwards, the job computer will switch the valves earlier or later accordingly.

 You are using the automatic SECTION-Control.

1. Read the operating instructions for the TRACK-Leader app to find out how to determine the

delay times.

2. Determine the delay times.

3. Open the job computer application.

4. On the work screen, press:

> > > > > ⇨ The “SECTION-Control” screen appears:

5. Enter the determined delay times under “Delay on start” and “Delay on stop”.

“Delay on Start” parameter

Time that elapses between the opening of a section valve and the emergence of liquid out of the nozzles.

Rule of thumb: ▪ If the sprayer switches too late, increase the value of the parameter. ▪ If the sprayer switches too early, decrease the value of the parameter.

“Delay on Stop” parameter

Time during which the nozzles continue spraying after the valve has been closed.

Rule of thumb: ▪ If the sprayer switches too late, increase the value of the parameter. ▪ If the sprayer switches too early, decrease the value of the parameter.

Changing the display of areas on the terminal

You can make different settings to change the display of the areas on the terminal, e.g. for the TRACK-Leader application.

Configuring the nozzles - for field sprayers with pressure sensor regulation

By configuring the nozzle type, the job computer can calculate the current application rate based on the measured spray pressure.

You only have to configure the nozzles if a pressure sensor is installed on the field sprayer.

If no pressure sensor is installed on the field sprayer and the application rate is regulated only through the flow rate, then you do not need to configure the nozzles.

Nozzle assistant

The nozzle assistant serves the following purposes: ▪ To show how the nozzle type affects the possible application rates and speeds. ▪ To help with the correct selection of the installed nozzle type. ▪ To change the target rate.

Extremity nozzles

Extremity nozzles are nozzles with a different spray pattern from the other nozzles on the boom. They can either restrict the spray width, in which case they are used for spraying field edges (corner nozzles), or increase the spray width of a section (wide area nozzles).

Before using extremity nozzles, note the following: ▪ Wide area nozzles or corner nozzles can be installed as extremity nozzles. You can choose the

icon used to represent the extremity nozzle on the work screen.

▪ Extremity nozzles can be installed at the outer end of any section. ▪ The width of the spray cone is irrelevant for the ISOBUS job computer. It is never detected and is

not taken into account in the following calculations:

– when calculating the working width,

– when calculating the applied quantity,

– when calculating the tank content.

▪ The TRACK-Leader and SECTION-Control applications from Müller-Elektronik do not take

account of the width of the spray cone from the extremity nozzles; they treat them as normal nozzles.. If you are using these applications, you may have to adjust the working width manually.

Identifying the job computer

For systems with two ISOBUS job computers, you must identify both job computers. You must activate the so-called second connector on the main job computer.

The second connector is a virtual connection for a second ISOBUS job computer. By activating the parameter, you are telling the ISOBUS system that there is a second implement in addition to the implement that is controlled by the main job computer.

The terminal can then take account of the geometry of both implements and thus enable section control. In doing so, the position of the second implement is always indicated relative to the position of the first implement.

A second manifold with boom can be considered as the second implement - like the example in these instructions. However, a different implement can also be mounted behind the field sprayer or in front of the tractor.

Because the system described here does not have a second ISOBUS power socket, you must use a second ISOBUS power socket on the tractor.
