Bi-Directional error in T3RRA.
Symptoms:The implement consistently cuts when heading in one direction and fills in the other direction. Final grade is never achieved. If T3RRA software is halted and iGrade is run in ‘Plane Control’ only the problem goes away.Cause: There is a slight time la...
Tractor position icon is far above or below the surface.
Symptoms:When implementing the position icon appears to be a long way above or below the surface (the tractor icon will normally rise to surface height if it is below the surface, but as-applied cuts will be far too deep).Cause:The zero value has been incorrec...
Tractor position icon does not adjust when you zero against a benchmark.
Symptoms: You are parked over a physical benchmark and want to adjust the map location so that the related on-screen benchmark icon matches the location on the tractor icon. However when you perform the “Zero using a marker” action nothing changes. The icons ...
Map icon on the T3RRA software screen lags behind the actual field position.
Symptoms:The screen update appears to be “laggy”. When you turn a corner and are back on a straight path you may see that the position icon on the screen is still turning the corner.Cause:This normally indicates that the software is having to do a lot of calcu...
‘As-Applied’ not updating correctly
Symptoms: When on the implementation screen, the “As-Applied” Cut/Fill map was not updating as per pass on the field. Cause: Ensure the "Implement Width" is entered and they have "As -Applied" enabled. Solution: If "Implement Width" is entered and "A...
Project has moved N/S or E/W.
Symptoms: When you return to an existing job the map is no longer aligned with the position of the tractor. The project surface has moved North/South or East/West. Cause: Previously entered offsets have been cleared under the Machine tab in settings. ...
My drain design is no longer present in the ‘Apply’ wizard step.
Symptoms: The Cut/fill map of drain surface in the Apply step is representing no cut and no fill. The profile view in the Apply step of the drain is a solid red line. Causes: A drain design was created for one or more of the multiple drains in one projec...
My drains have ‘bumps’ in them that weren’t present when I designed them.
Symptoms: A drain line was created with a set profile but when implementing it seems to have unexpected deviations. Cause: Multiple drains were designed and have overlapping sections. The profile of a drain gets ‘overwritten’ by the profile of a subseque...
Implement is offset a large amount after 'zeroing'
Symptom:Your implement is offset by a large amount when you zero before implementing.Possible causes:A value has been entered into the Blade clearance causing the zeroed amount to be higher than normal.Solutions:
Starting Implementation
T3RRA Software implementation startup instructions for UCC1 1. Drive to a zero cut/fill area and place the scraper cutting edge on the ground. Drop a marker for future reference. (when zeroing on drains ensure that the position indicator is on the drain surfac...
Understanding how "As-applied" works
When moving earth there are three states:What you started with.What you intended to do.What you actually did.You start with the original field surface. You intend to end up with the field surface matching your design. An “As-applied” (or “As-built”) map is a r...
Understanding the relationship between the "As-applied" surface and the Dynamic Blade Limit.
The Dynamic Blade Limit (See the section of “Static Blade Limit” in the Limits Tab for disambiguation) relies totally on “As-applied” functionality to work properly. If this is not activated, or is not working properly, the blade limit will not work.T3RRA soft...
The Implementation Screen
When you begin implementation of your design, the display will show a cut/fill map as well as tools to assist in the implementation of the design. Screen features of interest include include: Setting Zero button. Cross-slope nudge control buttons....
1. Setting Zero
Important: Before work can begin, the system must be “zeroed”. Both the T3RRA software and iGrade™ must be zeroed. Important concepts: Benchmarks. Benchmarks are “control points”. These are known locations in or out of the field that can be ret...
2. Cross-slope Adjustment
T3RRA software is capable of sending cross slope commands to iGrade™. It can operate automatically based on the cross slope observed on the map at the current location. It can also be switched to manual and a cross slope value entered. To enable control (m...
3. Vertical blade shift
The blade shift buttons in T3RRA Cutta and T3RRA Ditch serve to manually shift the height of the blade, either up or down. The distance a single press will shift the blade vertically (called the ‘Blade shift increment’) is set in the 'Settings' window. As the ...
4. Cut/Fill information display
In the upper left corner of the screen more information is shown about current ground height, design ground height and the amount needing to be added/removed. The Horizontal color bar will display a color graded scale of cut and fill amounts and the white mar...
5. Progress bars
In the upper right of the screen are 2 percentage counters that show the amount completed. These are only shown when 'Enable as-applied calculations' is turned on. NOTE: the percentages count up what has been implemented so far, not what is left to do...
