Page 9: Description
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. -
Page 10: General Description
Software The information in this manual applies to systems with Version 7 AutoHeight panel software. When the panel is turned on, the software version and revision will be displayed for a few seconds as described in “Power Up Sequence” on page 37. -
Page 11: Hardware Components
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. - Page 12 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.
- Page 13 Control Panel The AutoHeight panel (Figure 5) is the main component of the AutoHeight system. The control panel uses the readings from the ultrasonic sensors to control solenoid operated valves that in turn adjust the boom height. The control panel will: •...

Page 14: 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. -
Page 15: Driving Through Ditches And Over Terraces
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. -
Page 16: Areas Of "No Crop" In Crop Mode
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. -
Page 17: Autoheight Sensor Capabilities And Limitations
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,... -

Page 28: Manual System Setup
Manual System Setup The AutoHeight system will not operate in automatic mode until the system has been completely configured by either the Automatic System Setup or Manual System Setup. It is recommended that the Automatic System Setup be used, but if necessary a manual system setup may be used. -
Page 29: Setting Up Hydraulic Valves
Setting Up Hydraulic Valves Each valve must be tuned correctly for optimum performance from the AutoHeight system. When setting up the valves, the sprayer booms must have room to move in their full range of motion. Make sure there are no obstructions, such as power lines, that the booms may come into contact with. - Page 30 1. Follow the steps, “STEP 1: Prepare the Equipment” on page 24 to “STEP 3: Prepare the Equipment” on page 24 (level booms, working RPM, etc.), before proceeding. 2. Ensure the AutoHeight panel is in MANUAL mode, at the run screen. 3. Navigate to the "More ?" menu prompt in the SETUP menu. Toggle the "AUTO (YES)" switch to confirm.

Page 37: Operation
This section outlines the AutoHeight system's features and controls during field operation. Before you can operate your AutoHeight system in AUTO mode, it needs to be configured either automatically or manually. If your control panel shows the power up sequence below and will allow AUTO mode, it has been configured. If your panel shows different messages after being powered up or will not allow AUTO mode, it will attempt to begin or resume Automatic System Setup. -
Page 38: Typical Operation
• New settings take effect once the run screen is displayed. When the AutoHeight system is in automatic mode, indicated by an "A" in the control mode portion of the screen, the AutoHeight panel shows the target boom height. The arrows indicate the AutoHeight system is making a correction to part of the boom in the displayed direction. -
Page 39: Press & Hold Functions
The run screen will show an "M" for each boom to indicate the system is in manual mode. When the MANUAL AutoHeight is in MANUAL mode, the boom may be controlled as usual with the boom control switches on the sprayer's multifunction handgrip. -
Page 40: Adjusting The Target Height (Setpoint)
The sprayer's boom lift control (main up or main down) switches provide a target height adjustment feature. If you press and hold either the main up or the main down switches for more than two seconds, the AutoHeight panel will switch ALL booms (left, right, main, and roll) to MANUAL mode. -
Page 41: Changing Between Soil And Crop Mode
÷ 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. -

High Oil Temperature Alarm The High Oil Temperature Alarm will sound if the AutoHeight valve block reaches a temperature of 95° C. This alarm will only sound once and will not repeat. The alarm is re-enabled each time the automatic mode is entered. If the alarm sounds, the screen will also show “VT Max”... -
Page 44: Minimum Height Mode
5 - Operation Minimum Height Mode Minimum height mode is normally used only for systems with five sensors (severe terrain kit). Since the five sensor system has two wing sensors that average the height, it is possible to have a boom tip close to the ground while still maintaining an acceptable average height. -

Page 47: Maintenance
Check to ensure hydraulic hoses, sensor cables, or debris are clear of the sensor. • Inspect the foam shield insert in each sensor. HARDI recommends to fit clean foam shields before spraying. Sensor preparation and maintenance Fitted into the bottom of the sensor is a foam shield (Figure 9) that can become clogged with dust and dirt. -
Page 48: At The End Of A Season
• Replace oil filter with new oil filter kit (A) (Part no. 75076900) in the HARDI AutoHeight hydraulic manifold annually. • If necessary, contact your HARDI dealer to have the sensors recalibrated or repaired. Over time, performance of the inexpensive transducer element may become degraded from airborne contamination. -
