Theory of Operation The Terrahawk ground penetrating radar sensor is designed to mount on the header of an agricultural harvester to measure the distance to the ground and/or crop. This data may be used for header control as well as logged for analysis. Sensors should be mounted in accordance with the installation manual for the specific header being used. Terrahawk sensors are connected through a CAN bus on the header to a Horizon base controller mounted on the header near the single point connection. The user interface for the Horizon base controller is generally an OEM or aftermarket UT in the cab of the combine. This manual explains the operation and settings for the Terrahawk units through Horizon interface on the UT. 5 2. Sensor Power and Status 2.1. Powering the Terrahawk sensors 1. Terrahawk sensors are powered by connecting them to the Horizon 2. The Horizon CAN network is tied to key power so the sensors are emitting header CAN network. when the machine is keyed on. 2.2. Sensor light Status The LED near the connector of the sensor indicates its status. 1. Flashing green active, emitting and receiving signal 6 3. Setup 3.1. System Setup 1. On the UT interface in the cab, open the Horizon pool, and press the Setup softkey on the right. 2. Press the System tab along the top. 3. Input the information of your combine and header. a. For Sensor type select Terrahawk b. Check Feathersight if you have a platform head and plan to run near the ground 3.2. Assigning Sensors 1. On the UT interface in the cab, open the Horizon pool, and press the Setup softkey on the right. 2. Scroll over in the tabs along the top and press Terrahawk Sensors. 3. The sensor locations are displayed on the screen and the last 3 digits of each sensor serial number are display on the sensor icon. The location of these serial numbers must match the actual location of the sensors on the head. 4. Horizon has the ability to read the serial number of each Terrahawk sensor but cannot tell the location of the sensors on the head. During initial setup of the system, it will guess that the sensor with the lowest serial number is on the left and that each sensor position moving across the head to the right has a higher serial number. 5. If two serial numbers are in the wrong place, simply press the icons of the two incorrect sensors on the screen and the serial numbers will be swapped. 7 3.3. Range 1. On the UT interface in the cab, open the Horizon pool, and press the Setup softkey on the right. 2. Scroll over in the tabs along the top and press Terrahawk Sensors. 3. The range setting specifies the allowable range of operation (min to max cut height) in millimeters. 450mm (18 inches) often works well. 4. Increasing the Range value gives a larger allowable range of cut height but reduces the amount of sensitivity within the range. 5. Decreasing the Range value gives a smaller allowable range of cut height but increases the amount of sensitivity within the range. 8 3.4. Offset 6. On the UT interface in the cab, open the Horizon pool, and press the Setup softkey on the right. 7. Scroll over in the tabs along the top and press Terrahawk Sensors. 1. After setting the range, an offset can be added if needed. The offset is input in millimeters and is used to shift the range up from the ground. This allows you to increase cut height without increasing the range (since increasing the range will decrease the sensitivity). 2. The default value for offset is 0 and if your desired cut height is within 18 inches of the ground, it is probably fine to leave it there. 3. By definition, the offset value is raising the bottom end of the operating range - so if you add an offset, you will no longer be able to cut at the ground. 4. The combine will perform the best if you use an offset value that allows you to cut in the center of the combines height range. 5. Since having an offset value means you cannot cut close to the ground the Feathersight option must be turned off (Setup softkey, System tab). 9 3.5. OSD / ISD 3.5.1. 1. It is difficult for a Terrahawk sensor to Theory of Operation see things that are very close to it. Sometimes the sensor will see something (or think it sees something) in its very near field vision. The sensor is most responsive to things that are close to it, so when this happens it tends to overreact and quickly raise the header out of the crop. OSD and ISD stand for Outer Start Distance and Inner Start Distance respectively. This is the start distance where the sensor will begin looking so if something comes closer to the sensor than this value, the sensor will ignore it. Properly setting OSD and ISD can significantly improve the stability of the header control. OSD and ISD should be set as large as possible without missing values (representing objects) that are critical. 3.5.2. Setting OSD and ISD 1. Set the header on the ground. 2. On the UT interface in the cab, open the Horizon pool, and press the Diagnostic softkey on the right. 3. Select the Overview tab along the top. 4. If all sensors are mounted under the head, the reading of each sensor should be approximately the same. In the screen shot shown, the outer sensors are raised terrace mounts out in front of the end dividers so the value of the outer sensors is much higher. 5. First set the ISD. Since the header is resting on the ground, the value of the inner sensors should theoretically never go below 65 if the ground is level. However, the purpose of the sensor it to read variance in the ground so a good setting might be 35. This is 30 mm less than the bottom of the range meaning that if the head is all the way on the ground and there is a 30mm variance in the ground from one radar reading to the next

(a very short time ) the radar should be 10 able to see it. 6. Next set the OSD. The same principle applies, the lowest value in the example is 1056. Since these sensors are farther out in front of the combine, there could likely be more variance so a good value for OSD would probably be around 1000. 11 4. Operation 1. Be sure initial settings have been entered and Horizon has been calibrated. 2. Calibrate the Header to the combine per combine operators manual. 3. Operate the Headsight Height control system the same as an OEM combine height control system. 4. Fine tune all combine speed and sensitivity adjustments for best performance. 12 13 This page is intentionally left blank. 14 15
