2.2.3. Sensor X (Determination of the distance)

•

Installation on a Unimog (Unimog without a signal socket)

A tacho adapter is supplied with the Unimog. Dismantle the tachometer shaft from the gearbox and screw the adapter supplied in its place.

Apply multi-purpose grease to the shaft with the magnets and insert it with the yoke pointing downwards.

Screw the tachometer shaft on to the free end of the adapter.

•

Installation on a 4-wheel drive tractor and on a MB-Trac:

Mount the hose clamp with the magnet to the cardan shaft.

The sensor should point towards the magnets from a distance of 5 - 10 mm. It should be fitted so that no oscillation occurs.

(20)

•

Installation on tractors without a 4-wheel drive:

Fit the magnets to the shell of the wheel at an equal distance apart round the circumference with the V4A screws supplied

The number of magnets is determined by the size of the wheel.

The distance travelled between two impulses should not exceed 60 cm.

Calculation: Circumference of wheel ÷ 60 cm = number of magnets

e.g. 256 cm ÷ 60 cm = 4,27 = at least 5 magnets

Fit the sensor to the axle steering bearing with the brackets provided in such a way, that the end of the sensor points towards the magnets. The distance should be 5 - 10 mm.

2.2.4. Sensor Y (Working positi on)

The sensor Y (18) is connected to the tractor signal distributor (16) via the 3-pin socket. From this sensor the working position of e.g. the three-point hydraulics on soil-tilling work or the lifter on beetharvesters is recorded. If there is a switch box, the computer receives its information about the working position via the machine plug (4); the sensor in this case has no function.

The magnet is mounted with the V5A bolt supplied to a part of the machine, which changes its position from transport to working position. The sensor is then fixed to a static part of the tractor opposite to the magnet. When in operation, the magnet must be exactly in front of the sensor. The light diode "ACTION" lights up on the computer.

Whenever the part of the machine which is being monitored moves more than 4 cm in front of the magnet switch in working position, a second magnet is fitted in the direction of the movement of the magnet. When the implement is brought into transport position, the magnet should move at least 40 mm away from the magnet switch.

Example: Tractor - three-point hydraulics

3. Operating instructions

3.1. Description of the functions

•

Display

The SPRAY-Control S has an 8-digit numerical display. During operation the current speed (km/h) and the spray rate (l/ha) can be read at a glance.

The display shows the machine data and the operating data selected The "on" and "off" keys are on the left beside the display. The control lamps "distance impulse" (wheel / cardan shaft / radar), "boom section" and "working

position" are on the right. The "boom section" lamp lights up when one or more boom sections are switched off. The "working

position" lamp must light up when spraying is in progress.

•

Decimal keyboard

The decimal keyboard can be used to carry out the four basic arithmetical functions and to enter machine data.

•

Operating data

This keypad can be used to retrieve data required. By pressing the "Enter" and "C" keys simultaneously, the order is started. All numbers except ∑ha

and ∑l are set to 0. The operating time entry is started.

•

Machine data

This keypad is used to communicate the machine data to the computer. With the "+/-10%“ keys it is possible to vary the spray rate in degrees of 10% in relation to the pre-

set rate

3.2. Description of the machine data

Before the device is ready for operation, the machine data must be entered.

3.2.1. "Working width" key

This key is used to enter the working width > Press the "working width" key > The value is entered via the decimal keyboard > Press the "enter" key (=)

3.2.2. "Km/h sensor" key

The SPRAY-Control S has 3 inputs to record the distance travelled. The sensors X - wheel / cardan shaft and radar - can be connected to the tractor signal distributor and the sensor X (field sprayer wheel) can be connected to the machine signal distributor.

The SPRAY-Control S can only evaluate one sensor during an operation process. The "km/h" key is used for the selection.

Enter 1 = wheel / cardan shaft sensor

2 = radar 3 = wheel - attached sprayer

For all three inputs the calibration rate "impulses/100 m" can be stored. The sensor selection can be changed during operation.

Selecting the sensor (e.g. wheel / cardan shaft)

> Press the "km/h - sensor" key > Press "1" > Press the "enter" key (=)

3.2.3. "Impulses / 100 m" key

This key is used to enter the number of impulses which the installed sensor (see 3.2.2.) communicates to the computer.

The entry can be made in two ways:

1. The rate impulses / 100 m is known

> Press "impulses / 100 m" key > Enter the rate via the decimal keyboard > Press the "enter" key (=)

Note! Before entering the impulses/100 m, select the sensor required (see 3.2.2.)!

2. The rate impulses / 100 m is not known

> Measure and mark out a distance of 100 m on the field > Set the vehicle in start position > Press the " impulses / 100 m" key and the "C" key simultaneously > Drive the 100 m, the computer now counts the impulses > Press the "enter" key (=)

The SPRAY-Control S automatically selects the input, to which the sensor is connected. If more than one sensor is installed (e.g. cardan shaft and wheel - sprayer) the impulses / 100 m from both sensors are registered. The sensor with the highest priority is automatically selected. The "wheel sprayer" sensor has the highest priority, then radar and wheel / cardan shaft.

3.2.4. "Number of boom sections" key

This key is used to enter the number of boom sections (max. 12) and the number of nozzles for each boom section.

The boom sections are numbered from left to right, as seen from the direction of operation When the entry is being made, the boom section is shown on the left-hand side of the display and

the number of nozzles on the right. Procedure:

> Press the "number of boom sections" key

On the left a 1 (boom section 1) is displayed and on the right the number of nozzles

entered > If the value is to be changed, enter the new figure via the decimal keyboard > Press the "enter" key

The value is now stored. On the left a 2 (boom section 2) is displayed. If the figure

displayed on the right - number of nozzles - is correct, the boom section 3 can be

selected by pressing the "enter" key. This process can be repeated for up to 12 boom

sections. After that the total number of nozzles is displayed.

If e.g. the field sprayer has 5 boom sections, a 0 is entered when the 6th boom section

is displayed. The computer sets the 7th to 12th boom sections automatically to 0. In

this case the computer assumes 5 boom sections.

3.2.5. "Pre-set rate l/ha" key

Here the required spray rate can be communicated to the computer. If the switch is in the automatic position, the electronics monitor the pressure and subsequently the spray rate automatically. The monitoring procedure can be observed via the "+" and "-" displays.

If, due to a fault, the pre-set rate is not reached (e.g. empty bin), the horn sounds and the "+" and "" lamps in the 10% keys both light up.

Enter the rate "l/ha"

> Press the "pre-set rate l/ha" key > Enter the rate (e.g. 260) via the decimal keyboard > Press the "enter" key

By pressing the "pre-set rate l/ha" key a second time, the rate entered can be checked.

3.2.6. "Impulses / litre" key

The number of impulses, which the liquid flow meter per litre communcates to the computer, can be entered here.

The entry can be made in two ways:

1. The rate "impulses / litre is known > Press the "i mpulses / litre" key > Enter the rate via the decimal keyboard > Press the "enter" key (=)

2. The rate impulses / litre is not known or is to be checked > Fill the tank with water and establish the amount (weigh) > Press the "impulses / litre" and the "C" keys simultaneously > In standing position, switch on the field sprayer and spray a few hundred litres

(the computer calculates the impulses from the liquid flow meter) > Establish the amount sprayed (weigh back) > Enter this value via the decimal keyboard > Press the "enter" key (=)

The computer has now calculated the " impulses / litre" rate

The impulse count of the liquid flow meter should be checked several times a year, especially before each season.

3.2.7. "Constant / type" key

This key is used to enter 2 functions. The number before the comma and the 1st position after the comma determine the

The 2nd position after the comma determines the type of

control constant

3.2.7.1. Control constant

A certain deviation from the pre-set rate can occur, depending on the construction and size of the sprayer, so that different control times are required.

The computer calculates this control time, with which the control ball valve is regulated. The control time is affected via the control constants.

- Control too slow -> enter higher rate

- Over-control -> enter lower rate

The contol constant is ideally selected, when, in the case of deviation from the pre-set rate, the computer requires one control step to get close to the pre-set rate and a few small control steps for the fine adjustment.

control unit

The control status can be followed on the one hand by means of the l/ha display and on the other hand from the switching noise of the relay board in the switch box. Control constants from 0.5 to 10 are feasible. See also 3.2.7.2. "Control unit type"

Control chest type (last digit)

Motor valve contol unit or equal pressure control unit without return flow measurement

- The control unit is constructed with motor valves without return flow measurement The liquid flow meter measures only the quantity sprayed above the spray ridge, even when the boom section is switched off.

- The control unit is constructed with electrovalves and separate equal pressure valves (e.g. Tecnoma-Elektra). The spray liquid, which flows back to the bin via the equal pressure valves when the boom section is switched off, is not recorded by the liquid flow meter.

Electrovalve control unit without equal pressure function

The control unit is constructed with electrovalves. The liquid flow meter measures only the quantity sprayed above the spray ridge, even when the

boom section is switched off. If one or more boom sections are switched off at the end of the field when the sprayer is switched

off, the computer takes a pre-set figure from the control ball valve. The fine adjustment is then carried out after the field sprayer has been switched on.

Equal pressure control unit with return flow measurement

The control unit can be constructed with electrovalves or motor valves. The liquid flow meter also measures the amount which flows back to the bin when a boom section is switched off. The computer takes this into account when calculating the quantity sprayed.

Example: Field sprayer with 4 boom sections

One boom section is switched off, only ¾ of the measured quantity is registered. (1/4 flows back to the bin).

Note! The equal pressure control unit's valves must be set exactly.

3.3. Description of the function keys

3.3.1. "Start function"

The start function is triggered off by pressing the "=" and the "C" keys simultaneously, i.e the memory for the area, spray liquid, time and distance is set to "0". This action automatically sets the time going. This function has to be carried out before operation begins.

3.3.2. "Area" key

With this key the area worked after activating the start function (3.3.1.) is displayed. Boom sections, which have been switched off, are automatically taken into account. If the field sprayer is switched off at the main switch (the main switch lamp is out) the area measurement is interrupted.

3.3.3. "Total area" key

The total area from a season can be determined with this key. Before the season begins, the memory is set to "0" by pressing the "total area" key and the "C" key simultaneously.

3.3.4. "Time" key

The operation time since activating the start function (3.3.1.) is displayed when this key is pressed. When the computer is switched off, the time recording is stopped. It is restarted automatically as

soon as the computer is switched on again. The clock can be stopped during operation. After pressing the "time" key, press it again to stop the

clock. It can be restarted by pressing the "time" key yet again.

3.3.5. "Distance" key

The distance covered since activating the start function (3.3.1.) is displayed with this key.

3.3.6. "Spray liquid l/min" key

The spray rate in l/min is displayed when this key is pressed.

3.3.7. "Spray liquid l/ha" key

This function is displayed during operation. The speed and the current spray rate in l/ha can be read. This allows the operation process to be monitored.

3.3.8. "Spray liquid l" key

The start function (3.3.1.) sets this counter, as well as the counter for the area, to "0". This means that at the end of the process the area worked and the spray liquid applied on that area can be read.

3.3.9. "Total l" key

The use of this counter can be allocated freely. If the "C" key is pressed at the same time, the counter is deleted

It can be used e.g. to monitor the contents of the tank. After filling the counter is set to "0". The average quantity sprayed can be read during operation.

3.3.10. "Performance - ha/h" key

The average performance per hour is displayed when this key is pressed.

Seite - 18 - Copyright Müller-Elektroni k GmbH & Co., Salzkot ten Installation and User's Guide SPRAY-Control S (12/94)

3.4. Operating procedure

After entering the machine data (3.2.1. - 3.2.7.) only the start function (3.3.1.) has to be activated, before work can begin. During operation all values can be retrieved. The 4 basic arithmetical functions can also be carried out during operation.

The automatic guarantees exact dosage. Because of the forming of drips, it is important to maintain the pressure for the type of nozzle used.

If possible, the same speed should be driven at the time when the field sprayer is switched on and when it is switched off. This is to prevent a short-time underdose or overdose after the field sprayer is switched on.

If monitoring is to be carried out manually, the switch "hand/automatic" must be set to "hand" on the switch box. The amount can be regulated with the +/- keys.

All values can be retrieved at the end of operation. A new process begins with the "start function" (3.3.1.)

Note!

Before putting the field sprayer into operation for the first time, it should be filled with water (not spray liquid). Start operating the field sprayer. Afterwards check the measured and the displayed values.

4. Maintenance

4.1. Computer

The computer is maintenance-free. It has an internal electrical fuse. During winter it should be stored at room temperature.

4.2. Liquid flow meter

The liquid flow meter has to be rinsed with water each time after use. At the end of each season the run of the impeller should be checked, and if necessary replaced. The calibration process should be carried out at the beginning of each season. (see 3.2.6.).

5. Guarantee

The liquid flow meter is guaranteed for six months. On all other components - computer, speed sensor, ball valve - a guarantee period of 12 months is applicable.
