About the job computer

3.1

Job computer functions

The SPRAYER-Controller MIDI 3.0 job computer is an ISOBUS job computer 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.

3.2

System Overview

The main system always consists of a base job computer, onto which other additional components can be installed. The overall system can have various sizes depending on these additional components.

3.2.1

Example: SPRAYER-Controller MIDI 3.0 with DISTANCE-Control II and EDS
Main system – MIDI
The system can be expanded. The basic version consists of one to three job computers. The first job computer is connected to the ISOBUS power socket on the tractor.

Procedure

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. The connection cable must be mechanically supported in the area of the installation site (distance < 150 mm) so that an in-phase stimulation takes place. Do not use the system if some of its parts are damaged. Damaged parts can cause malfunctions and lead to injuries. Replace damaged components. Only use original components.
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.

30303187-02-EN-200

4.3.1
Procedure

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 connection in 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 sensor connection cable for each sensor. You must insert the sensor connection 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.
NOTICE
Risk of short-circuit When exchanging the polarity of cable cores, machine sensors can be damaged by a short-circuit. Pay attention to the polarity of the cable cores and the terminals.
The junction box is not powered. There is no voltage on the components to be connected. 1. Remove the cable coating so that all cable cores are exposed.

Mounting and installation
4 Installing the junction box

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.
4. CAUTION! Pay attention to the proper polarity of the cable cores and the terminals.
5. Connect the cable cores to the terminals. [ 24] 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. Close the screw connections of the junction box. After screwing them shut, the glands should be sealed.
7. Close unused openings in the casing of the junction box with blind caps.

4.3.2
Procedure

Inserting the cable core into a terminal
Each terminal consists of two openings: The upper opening or the orange opening point of the terminal opens 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 no 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 are not using wire end sleeves, you first have to use the screwdriver.
The cable core will be held by the terminal. You have clamped the cable core.

“Target Rate” parameter
The quantity entered as the target rate will be applied when the sprayer is working in automatic mode. You can configure up to three different target rates, between which you can switch on the work screen.
“Jump start time” parameter
With this parameter, you can simulate the speed after switching on the sprayer (at least one section will be switched on). The set simulated speed is then used for the entered “Jump start” duration before switching to the regular speed. If the simulated speed is 0, this parameter is deactivated. With the “Jump start” duration, the application rate is increased when starting off to prevent insufficient application rates at the beginning of the field.
“Working Width” parameter
Working width of sprayer.
“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. If the “Pressure limit” parameter is configured on your sprayer, the minimum pressure set there will not be undercut while spraying.
“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. If the “Pressure limit” parameter is configured on your sprayer, the maximum pressure set there will not be exceeded while spraying.

“Sprayer off Below” parameter
(Minimum working speed) If the sprayer speed drops 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 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.
The work screen displays the icon 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 of the nozzles is adapted to the current speed of the 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 rate, 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.
For the regulation factor, you can also define permissible deviations.
– Switch to the “Spray regulation” screen. There, you will find the “Large deviation” and “Smallest deviation” parameters that you can configure for the regulation factor.
The “Large deviation” controls the regulation factor if there is a large deviation between the target and the current value and the “Smallest deviation” controls the regulation factor if there is a small deviation between the target and actual value.
The “Large deviation” controls the regulation factor if there is a large deviation between the target and the current value and the “Smallest deviation” controls the regulation factor if there is a small deviation between the target and actual value.

When should you calibrate?
Methods

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.
NOTICE
Imprecise calibration If the calibration is imprecise, the calculations will be very inaccurate and the application imprecise.
Calibrate the flow meter very precisely.

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 implement 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 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:

The “Speed” screen appears. 2. Configure the “Speed source” parameter. If the “Speed source” parameter does not appear on the “Speed” screen, and the speed signal should be received through the ISOBUS, proceed as follows: The speed signal can be received through the ISOBUS. 1. Switch to the “PARAMETERS” screen:

2. Set the “Wheel impulses” parameter to “0”.

Calibrating the speed sensor with the 100m method
When calibrating the speed sensor with the 100m method, you determine the number of impulses received by the speed sensor in a distance of 100m. When you know the amount of impulses, the job computer can calculate the current speed.
If you know the number of impulses for the wheel sensor, you can also enter this number manually.

If the trailed implement or the tractor sends a reverse driving signal through the ISOBUS, the job computer can use this signal to adjust its regulating behaviour when driving in reverse.
You can find more information in this section: Configuring automatisms when driving in reverse [ 133] The following signal sources are possible: “None” – The job computer should not expect a reverse driving signal. Even if a reverse driving signal is transmitted through the ISOBUS, the job computer will ignore the signal. “ISOBUS” – The reverse driving signal is sent by the tractor or a different job computer through the ISOBUS. “Sensor” – A reverse driving sensor is connected to the junction box or cable harness of the job computer.
To select the reverse signal source:
1. Switch to the “Speed” screen:

2. Select the box below the “Reverse drive sensor” parameter. The available signal sources appear. See the description at the beginning of this section.
3. Select the signal source.

Procedure

“Simulated Speed” function
The simulated speed function is only used during tests and when looking for faults. It simulates the movement of the implement when the implement is at a standstill. By activating the “Simulated speed” function, it is possible for customer service employees to check the correct functioning of a sensor. By default, the value is set at 0 km/h and the function is switched off. After restarting the computer, the function is always deactivated. The most recently set value is saved and used for the next activation. 1. Switch to the “Speed” screen:

– Activate the simulated speed. By pressing again you can deactivate the function.

The “Simulated speed” line appears.

3. Enter the speed to be simulated on the “Simulated speed” line.

– Exit the screen.

Switching sections off permanently
You can permanently switch off any section. This is useful, for example, if the tramlines on the field are designed for a smaller field sprayer than yours. Switching off the outer sections has the following effects:
With TRACK-Leader: The newly calculated working width will not be taken into account for the calculation of the headland width.
With SECTION-Control: After switching off the outer sections, you will need to change the “Line spacing” parameter so that the distance between the guidance lines matches the actual working width. You cannot change the “Working width” parameter.
The actual working width changes. However, as the sprayer has not changed: ­ Do not change the “Working width” parameter. ­ Do not change the sprayer geometry.

Procedure

Permanently switched off sections are marked in white on the work screen 1. Switch to the “Boom” screen:

The “Boom” screen appears.

– Press.

The “Sections” screen appears.

For each section, you can see one of the following icons:

– Section activated

– Section deactivated. 3. For each section, you can select and change this icon.

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.

“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.

Configuring the nozzles – for 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 sprayer.
If no pressure sensor is installed on the 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.

Current nozzle output. When you change the pressure, the newly calculated nozzle output appears.

Nozzle output at 3 bar – Result of the calibration
For non-standard nozzles, the calibration must be repeated at a different pressure. This pressure should be about as high as the intended working pressure.

WARNING
Spray liquid or spray liquid residues Danger of poisoning or chemical burning Clean the spray liquid tank thoroughly prior to calibration. The sprayer must be free of spray
liquids or spray liquid residues. Use only clear water during calibration. Wear required protective equipment.
Calibrate a standard nozzle as follows: The tank is filled with clear water. There are no spray liquid residues in the tank or the pipelines.

– On the work screen, switch the application mode to manual.

– Start application

and

– Set the spray pressure to 3 bar.

4. Using a measuring cup, collect the water from several nozzles for one minute each.

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.
