General info

Introduction

Congratulations on your purchase of the HARDI AutoHeight system (UC4+ version). The system is manufactured with top quality components and is engineered using the latest technology to provide operating features and reliability unmatched for years to come.

When properly used, the AutoHeight system can provide protection from sprayer boom damage, improve sprayer efficiency, and ensure chemicals are applied correctly.

This manual is intended to be used in conjunction with the:

• AutoHeight Installation Manual

• Sprayer Instruction Book

The manual provides a general description of the spray height control system, a section regarding system operation, and discussion related to understanding performance issues. Also provided are instructions for the use of the control panel, information regarding system setup, regular maintenance and troubleshooting.

Please take the time to read the complete instruction book before attempting to use the system. Although the AutoHeight system has been designed for easy set-up and use, a thorough understanding of the information provided will ensure that you receive the maximum benefit from the system.

Key features

The key features of the HARDI AutoHeight is:

Non-contact Sensing

• Sensing is done using ultrasonic sensors which means no parts of the HARDI AutoHeight system come in contact with the ground.

• Using a non-contact system means there will be no additional forces put on the boom, which could cause damage to the sprayer boom.

Automatic Software Setup

• The system completes an automatic system setup, which calibrates the software specifically for the sprayer.

• This provides the maximum performance for the height control system.

Individual Boom Overrides

• When necessary one boom section can be put into manual mode to avoid an obstacle, while the other boom sections stay in automatic.

• This can take the stress out of spraying along obstacles such as fences because you only have to watch the boom along the obstacle, knowing that the HARDI AutoHeight system is maintaining the height on the rest of the boom sections.

Smart Sensor Technology

• All sensors are designed specifically for the agricultural industry.

Hardware components

The components of the HARDI AutoHeight are:

Cables

The system will function properly with a power supply between 12 and 28 volts and may draw up to 10 amperes during normal operation.

The AutoHeight panel contains intelligent valve drive circuitry that helps to protect the sprayer's system against short circuits and other wiring problems. However, it is still recommended to connect the AutoHeight power cable to a fused supply that turns on and off with the ignition key of the sprayer/tractor. For more information on cables, please see the AutoHeight Installation Manual.

Sensors

Three sensors are provided with your AutoHeight boom control kit. The sensors use an ultrasonic signal to measure the distance to the ground, or the top of the crop. Three sensors are required to provide good overall height management of the boom. Two sensors are mounted on the outer sections of each wing (Figure 2). These sensors maintain each wing at the set target height independently.

The third sensor is mounted on the centre section. The boom lift sensor is useful for setting your initial spray height when you begin spraying in a field.

It is true that the centre section height will not change much, in consistent soil conditions, since both ends of the centre section follow the height of the power unit. However, it is extremely difficult to judge the boom's actual height accurately from the cab. It is also very difficult for the operator to see the main section nozzles. It is common for operators to be in error from 20 to 30 cm or more. The AutoHeight panel will give you an actual height reading in the cab and allow active control to the desired height.

The reason for the centre section sensor is that soil conditions change along with the weight of the machine. As the sprayer tank fluid level changes throughout the day and soil conditions vary, the centre section height will change because of the amount the tires sink into the soil.

Special attention must be taken into consideration when mounting the centre section sensor, as explained in the AutoHeight Installation Manual for your sprayer.

The ultrasonic sensors are designed to work best in the brackets provided (Figure 2). If you decide to use a different style of sensor mount, you may limit the performance of the sensor and/or void your warranty. Further, it is important to follow the guidelines in the AutoHeight Installation Manual for mounting the sensors. The sensors should be at least 25 cm above and 25 cm in front of the spray nozzles.

For large boom or severe terrain applications, an additional sensor may be mounted near the midpoint of each boom to obtain an average height reading. The average height reading will provide improved height control over the length of the boom and protect the boom in severe terrain conditions. See “Figure 3 - Severe Terrain - Additional Sensors Required” on page 12.

Figure 3 - Severe Terrain - Additional Sensors Required

The centre section sensor can also be used to adjust the slant angle of the entire boom. Alternatively, slant sensors can also be used to adjust the main slant angle of the entire boom. Addition of this sensor to the AutoHeight system can greatly improve the speed and stability of the automatic control actions.

Figure 4 - Slant Control of the Main Frame

Height Sensors

• Height sensors use an ultrasonic signal to measure distance to the ground or crop canopy.

• Normally there are three height sensors used, but a system may have as many as 6 sensors. A sensor is mounted to the

outer part of each boom tip, and another sensor is mounted to the centre section.

Roll Sensors

• Roll sensors are important for measuring boom and sprayer roll dynamics.

• Two roll sensors are normally used for a UC4+ Spray Height Control System.

• The mounting position of the roll sensors varies from sprayer to sprayer depending on boom geometry and

suspension.

Understanding Your AutoHeight System

Understanding Performance Issues

Your AutoHeight will work well in most situations. However, as with any equipment, it is important that the operator remains alert at all times. There may be some field and terrain situations where performance is diminished. In these situations the operator must resume height control of the booms manually. A discussion of performance issues is given below to help clarify these situations.

Sensitivity (Sensi) Setting

The AutoHeight system is configured to work well in most conditions, with warm hydraulic oil, at a sensitivity (Sensi) setting of five. When you first begin operation at the start of a day, it may be necessary to operate at a higher sensitivity until the oil has reached normal temperature. After warmup, keep decreasing the Sensi setting until the performance is optimized, to avoid overheating of the hydraulic oil.

Different types of terrain may require different Sensi settings. The Sensi setting controls more than just response time. It also determines how accurately the AutoHeight system will try to correct for height errors. The higher the sensitivity the higher the accuracy. At low sensitivity, a few cm of error will be tolerated. At high sensitivity, virtually no error will be tolerated. Therefore, the system will be much more active at high sensitivity than at low sensitivity.

NOTE! Running AutoHeight at high sensitivity will increase heat build-up of the oil. Specially when AutoHeight

system is used with tractors that have an open centre system without load sensing, it may require lower sensitivity settings to avoid overheating of hydraulic oil. See “Hydraulic hook-up” on page 23.

NOTE! Field conditions and operator preferences determine the appropriate Sensi setting.

Boom Reaction Time

There are two key factors that determine how quickly your boom can react to changes in terrain. The first factor is the available hydraulic speed. The maximum hydraulic speed of your boom was designed by the sprayer manufacturer and is not improved or diminished with the addition of the AutoHeight height control system.

The second factor is the mechanical design of the sprayer. The Sensi setting does affect the reaction time of your boom

- the higher the number the quicker the response. However, how high you can run the Sensi setting is determined to a large extent by mechanical issues related to the boom and sprayer.

Important design issues include the style of boom mount (for example, centre pivot or nonparallel links), the amount of mechanical damping and spring centring on the boom lift mount, and whether a boom slant system is available on the sprayer. All of these factors together determine the maximum Sensi setting you can run on your AutoHeight system. This, in turn, will set the reaction time of the boom in a given situation.

The AutoHeight electronics are rarely the limiting factor in determining overall automatic height control performance.

AutoHeight over Ditches, Waterways and Outside Rounds

Many situations exist where one sensor may be reading over terrain that does not accurately reflect the situation for the rest of the boom. For example, if you are spraying along a waterway, it may be necessary to run the outer boom sensor out into the waterway itself. This situation is similar to the picture in “Figure 3 - Severe Terrain - Additional Sensors Required” on page 12. In this example, the outer sensor will bring the boom lower than desired and may put the mid-point of the boom at risk. Outside rounds adjacent to very weedy areas or tall thick grass are examples of the opposite situation.

In these situations the operator must remain alert and override A UTO m ode when nece ssa ry. A ddit ion of th e opt ion al se vere terrain (inner) sensors will greatly improve performance in these situations.

WARNING! In most countries spraying over ditches and waterways is strictly prohibited! Always follow local

legislation!

3 - Description

Driving Through Ditches and Over Terraces

Changes in terrain that include driving over terraces or through ditches are special performance cases. This type of terrain can cause the sprayer to pitch and roll significantly. Sprayer operation at speeds of 15-30 km/h in severe terrain may result in rapid changes in boom tip height. In these situations, typical sprayer hydraulic systems are not capable of tip speeds high enough to correct for the induced error.

The sprayer’s roll control system will compensate for the sprayer roll in this situation and also add stability to your boom in normal operating conditions.

Alternative solution is for the operator to recognize these situations before they occur and manually raise the boom section(s) to a safe height. To return to AUTO mode, use the "AUTO (YES)" switch.

Sensor Capabilities

In order for the AutoHeight system to work at its maximum level of performance, the AutoHeight sensors must be returning accurate height readings at the designed frequency. Under typical conditions, the sensors can provide accurate height readings from 0.2 to over 3.0 m and return many height readings in one second. The target in SOIL mode can be identified through stubble, young crops, row crops, and normal trash. The target in CROP mode can be identified over cereal grains, specialty crops, and row crops. See the next section for more information on CROP and SOIL mode guidelines.

There are two main steps to ensure sensor performance. The first step is proper mounting. See “Hardware components” on page 11 for more information on sensor mounting. The second step is to ensure that the protective foam covers on the sensors are kept clean, and that the ultrasonic transducer behind the foam does not become corroded or excessively dirty. Extra foam pieces are shipped with your kit. The transducer is a maintenance item and can be replaced at HARDI service locations. Transducers can last up to ten years, depending on conditions. Refer to “6 - Maintenance” on page 47 for more maintenance information.

If the mouth of the sensor becomes wet, it is normal for the sensor to return error messages until the transducer has dried off. This could include rain or excessive overspray. Material ca n build up on the transducer if the s ensor is mo unted to o close to the spray nozzles. This is the reason that the sensor must be mounted at least 25 cm in front of the nozzles. It keeps the sensor housing out of the normal region of overspray.

In the sprayer boom application, the sensors ignore any target that is closer than 25 cm from the bottom of the sensor housing. This region is called the blanking range. Operating the sensor at heights near the blanking range is dangerous and will affect performance because height readings can be very intermittent. This is the reason that each sensor must be mounted at least 25 cm above the spray nozzles.

Understanding Crop Mode And Soil Mode

A unique feature of AutoHeight sensors is their ability to operate in CROP mode. In this mode the sensor will track the first available sonic target. That is, when positioned over standing crop, the sensor will return the average height of the heads in a circular area below the sensor. In the same situation in SOIL mode, the sensor will track the last available sonic target. That is, signals from the heads, leaves, and trash will be ignored in favor of the ground.

It is important to note that the targets must be available and of sufficient strength for the sensor to "see" them. There may be some crop and terrain situations that do not work well for CROP mode or SOIL mode. In these situations the operator must resume height control of the booms manually.

In general, the addition of the severe terrain kit will improve performance in CROP mode. All of the situations discussed below are lessened by the addition of the extra sensors on the wings.

3 - Description

Areas of "No Crop" in CROP Mode

If, while operating in CROP mode, the sensor encounters an area where there is no crop, the system will behave as follows. The sensor will track the soil (A) because only one target is available. The boom will lower (B) as no crop is detected. Areas like this may include missed areas during seeding, alkaline areas, and so on. When the problem area ends (C), it may not be possible for the sensor to see the crop again unless the operator raises the boom manually. The sensor may be closer than required 25 cm from heads of the crop (D), thus blanking out the desired target.

Figure 8 - Area of "No Crop" When Operating CROP Mode

Thin Crop

The AutoHeight ultrasonic sensors operate by bouncing sound waves off the desired target. A minimum signal level is required from the crop in order to use it for control purposes. This is no different than the fact that your radio must be at a certain minimum volume level before you can physically hear it. Different types of crop and crops at different stages of development return varying levels of sound. The following are some general guidelines.

• Crops in growing stages are relatively good sonic targets.

• Bearded crops are relatively poor sonic targets.

• In row crops, the sensor must be positioned over the row to use the crop signal, or between the rows to use the

ground signal.

• The desired target must cover roughly 60 percent of the area to be tracked consistently. That is, when looking at the ground, the heads should cover about 60 percent of the ground. Otherwise, you can use SOIL mode.

• If the sensor runs too close to the heads, they may not return enough signal to be seen, or they may be blanked out. The nozzles must be at least 55 cm from the crop. Slightly higher target height settings will work better in thin crop.

Boom Lift Sensor in Wheel Track

The required location for the centre section sensor is determined by the AutoHeight Installation Manual for your sprayer and by the options you have installed. Special attention is necessary when mounting the centre section sensor. Mounting the centre section sensor directly behind a sprayer tire may impair boom lift control when operating in CROP mode. Height readings from crop that is flattened by the sprayer wheel do not provide an accurate measurement of canopy height, resulting in poor performance.

Sensing Further Ahead of the Boom

A common misconception is moving the sensor further ahead of the boom will increase performance. Moving the sensor further ahead of the boom increases the distance between the nozzle and sensor. This puts the sensor at a different location within the field than the nozzles, which introduces a height error at the nozzles. In severe terrain this height error can bring the nozzles close to the ground as the sensor reads over the crest of the hill or down a ditch.

Similarly, aiming the sensors ahead (rather than pointing straight down) will reduce sensor performance by providing inaccurate height readings.

3 - Description

AutoHeight Sensor Capabilities and Limitations

The AutoHeight sensors are designed and built specifically for agricultural purposes. However, the ultrasonic transducer must be clean and dry for optimal performance. The foam disc fitted into the bottom of the sensor protects the transducer from dust. If the protective foams become wet (from rain, drift from the spray nozzles etc.) the sensors may have trouble reading.

The height sensors will provide height readings from 22 to 300 cm, under typical conditions. In order to optimize sensor performance, the AutoHeight sensor has a minimum distance that it will read (also known as the blanking range). As a result, the AutoHeight sensor is designed to ignore targets closer than 20 cm from the bottom of the sensor housing.
