For your safety

Basic safety instructions

Please read the following safety instructions carefully before using the product for the first time.



Hazard Area

The hazard area covers an area of several meters around the tractor and towed equipment in all directions. The greater the size of the towed equipment, the greater the hazard area. For example: The wider the spraying rods of an agricultural sprayer, the further it can swing out and therefore its hazard area is greater.

ƒ Nobody must stay in the proximity of the tractor or trailed implement during operation. ƒ Never remove any safety mechanisms or stickers from the product. ƒ Read the operating instructions to the agricultural device which you want to control by using the

product.

ƒ Before charging the tractor battery, always disconnect the connection between the tractor and

the terminal TRAIL-Control II.

ƒ Before welding on the tractor or implement, always disconnect the power supply to the terminal. ƒ Before maintenance or repair to the tractor, always disconnect the connection between the

tractor and the terminal.

ƒ Do not make any unauthorized modifications to the product. Unauthorized modifications or use

may impair safety and reduce the service life or operability of the unit. Modifications are considered unauthorized if they are not described in the product documentation.

WARNING

Danger of Injury from Uncontrolled Machine Movements

ƕ Pay attention that nobody enters the hazard area! ƕ Switch off the system immediately, as soon as a person enters the hazard area!

As soon as the system has been assembled and switched on, nobody may remain in the hazard area.

When the TRAIL-Controll II is switched on, there is a risk that pressure fluctuations in the hydraulic system could cause the drawbar or the steering knuckle to move uncontrolledly.

Pressure fluctuations can, for example, occur in the following instances:

ƒ If the hydraulic system is defective ƒ If the hydraulic system is used for purposes other than for controlling steering of the drawbar and

knuckle.

The hazard area may then only be entered if the following conditions are fulfilled:

ƒ The person entering the area must be informed of the potential dangers ƒ All activities must be precisely agreed between the driver and the person appointed to enter the

area.

ƒ All maintenance, configuration and monitoring work must, if possible, be conducted when the

system is switched off.

NOTICE

Imprecise calibration

The speed cannot be precisely determined with an incorrectly calibrated wheel sensor. This makes all calculations imprecise.

ƕ Calibrate the wheel sensor very precisely.

5.5.1

Preconditions

Determining pulses per 100 meters

When calibrating the wheel sensor with the 100m method, you determine the number of pulses received by the sensor over a distance of 100 meters.

When you know the amount of impulses, the TRAIL-Control II can calculate the current speed. In order for the wheel sensor to function correctly, it must receive at least 250 pulses over a distance

of 100 metres. With very long machines, even 300 pulses per 100 metres. To increase the number of pulses, you must mount additional magnets opposite of the wheel sensor.

; Wheel sensor is mounted. ; All wheel sensor magnets are fully functional. ; A distance of 100m has been measured and marked. The distance must correspond to the field

conditions. It should therefore lead over a meadow or a field.

; The tractor with connected implement is ready for a 100m drive and is at the start of the marked

distance.

1. Ensure that all prerequisites have been fulfilled.

2. Change to Wheel.Puls screen:

Calibrate steering

ƒ Prior to initial startup. ƒ At the start of each season. ƒ When inaccuracies occur.

5.6.1

There are two methods to calibrate the steering:

ƒ Teaching-in the central position and end stops

This method is suitable for implements without proportional valves. With this method you teach the On-board computer the position of the drawbar or swivel pin in the central position as well as the left and right end stops. All intermediate positions are calculated by the On-board computer itself.

ƒ Calibrating the hydraulics of the proportional valve

This method is suitable for implements with proportional valves. With this method the trailed implement is automatically steered to both sides and the voltage is measured. Calibration with this method is automatic.

Teaching-in the central position and end stops

The appearance of the screens during calibration depends upon whether your trailed implement is steered via drawbar or swivel pin.

The procedure is however identical for both cases.

Phase 1 Teach-in central position

1. - Set up the trailed implement on flat ground in a line behind the tractor.

Controls

Mode of operation

Switch between manual and automatic mode

The TRAIL-Control function controls the trailed implement. Here the direction in which the trailed implement is steered is the reverse of the direction in which the tractor is steered.



Steering a trailed implement in a curve

Trailed implement without steering Trailed implement with swivel pin steering Trailed implement with drawbar steering

The figure shows that the trailed implement must always be steered in the opposite direction to the direction of the tractor. Only in this way can the implement remain in the tracks of the tractor.

Minimum work speed

The minimum work speed for TRAIL-Control II is 3 km/h. Speeds lower than this mean the system does not function optimally.

Controls

Procedure

Steering in manual mode

You can use manual mode to steer the trailed implement in the following situations:

ƒ Steering the trailed implement when driving forwards ƒ Steering the trailed implement when driving backwards ƒ Steering the trailed implement into the central position

WARNING

Danger of injury from trailed implement movement

The complete implement moves during steering. This may cause danger for persons and materials in direct proximity to the implement.

ƕ Ensure that nobody is in the range of the implement before steering the implement.

Steer trailed implement to the left when the tractor drives to the right Steer trailed implement to the right when the tractor drives to the left Steer the trailed implement into the central position

You can see the progress on the work screen.

1. Driving the tractor to the right

6.2.3

3. Drive the tractor straight ahead.

5. Driving the tractor to the left

- Steer the trailed implement for driving to the right.

ֲ With drawbar steering: The drawbar is steered to the left. ֲ With stub axle steering: The wheels are steered to the left.

- Steer the trailed implement into the central position

ֲ The trailed implement moves slowly into central position

- Steer the trailed implement for driving to the left.

ֲ With drawbar steering: The drawbar is steered to the right. ֲ With stub axle steering: The wheels are steered to the right.

Steering in automatic mode

When you work in automatic mode the trailed implement is steered automatically. The gyroscope measures the directional change of the tractor and TRAIL-Control II calculates the

required angle for steering the trailed implement.

Steering the trailed implement against the slope

For work on a slope you can use the 'slope counter-steering' function. When you activate the 'slope counter-steering' function you can offset the track of the trailed

implement to the left or right. The direction in which the track is offset depends if the slope climbs or declines to the left or right of the vehicle.

Procedure

TRAIL-Control II with drawbar steering

Using slope counter-steering in manual mode

In manual mode you must steer the trailed implement manually against the slope. Here you can decide yourself whether the trailed implement should follow the track of the tractor or whether it should be offset.

- Activate 'slope counter-steering' function.

ֲ The work screen displays the icon

- Steer the trailed implement against the slope. When the slope inclines to the left of the vehicle you must steer the trailed implement to the left. When the slope inclines to the right of the vehicle you must steer the trailer device to the right.

- Deactivate 'slope counter-steering' function.

Using slope counter-steering in automatic mode

In automatic mode the TRAIL-Control II determines itself how far the machine must be steered against the slope.

Procedure

; You have installed a tilt sensor.

- Activate 'slope counter-steering' function.

Documenting work results

There are two types of meters for documenting work and evaluating this:

ƒ Day counter – documents the work until it is deleted. ƒ Total counter – documents the work since first start-up.

Both types of counters are found on the Counter screen. The first two lines are for the daily counter.



Counter screen

The Counter screen has the following information:

ƒ Time – time period of TRAIL-Control II in automatic mode. ƒ Distance – distance driven in automatic mode. ƒ Serv hours– time period in which TRAIL-Control II was switched on.

Locking TRAIL-Control II for road driving



Procedure

Locking TRAIL-Control II for road driving

Before driving the machine on a public road you must deactivate machine steering, and if possible lock with the locking sensor.

WARNING

Risk of accident from activated machine steering

The machine steering in road traffic can lead the pulled machine to the side of the tractor track. This may cause a traffic accident. Before driving the machine on a road:

ƕ Steer the machine into central position! ƕ Switch off TRAIL-Control II!

1. - Activate manual mode.

3. If you have locking bolts: Lock drawbar steering with the locking bolts.

- Steer the trailed implement into the central position.

- Disable all functions of TRAIL-Control II.

ֲ A blue screen appears with the text 'TRAIL-Control II'.

- Switch off TRAIL-Control II.
