1. EXCAVATORS

2. Excavator.dll : General Settings Contains:  Excavator Dimensions  System Override Values  Useful when a sensor fails  Sensor Adjustments.  Grapple Setup  Grapples can be fixed or have a sensor to detect thumb angle  Filter Setup  Auto Bucket Down  Used to mark bucket positions at certain depths  BKT Matrix Angles  Used to limit MTX updates to a range of angles of the bucket  Reach Adjustment  Used to correct for tilt error

3. Excavator.dll : Bucket Geometry  Contains:  Bucket Sensor location  When the sensor is attached directly to the bucket the sensor does not require any additional information

4. Excavator.dll : Dogbone Settings  Contains:  Bucket Dimensions  When the sensor is located on the “dogbone”, the measurements for each link must be entered.  The difference in the angle of the stick to the line between pins A and B must be computed.  The angle between the pins B and C versus the lint between pin B and the teeth must be computed and entered.

5. Excavator Calibration – RVG Example When Using an RVG (U.S. Digital Sensor chain) the calibration position is with the bucket teeth on the deck with bucket pin plumb with the teeth

6.  On an Excavator that is using an RTK GPS for tide there are two different methods that can be employed.  The user can reference the GPS Vertical Offset from the Boom Pin remembering that up is negative in our offsets. The other method is to measure the GPS Vertical Offset to the Water Line of the Barge the excavator is sitting on. In the second method you will also have to enter the height of the Boom Pin Vertical Offset from the Water Line. This method is preferred when the height of the water surface can be independently verified because the bucket can then be set to the water and the tide/water surface can be compared to the bucket final elevation to ensure vertical calibration. If the tide/water surface is not independently referenced and is not of concern then the first method is sufficient.

8. Excavator.DLL: Profile/Shapes Tab Contains:  Drawing Colors for various objects in the profile  The path to the shapes, every entry should be filled in.  The limits of the grid as it is displayed in the profile.  Pontoon Protection is used as a reach alarm, if the teeth are too close the alarm sounds in DREDGEPACK.

9. Excavator.DLL: Custom Setup Contains:  This setup uses the standard HYPACK style configuration for generic parsing of a string.  Items can be repositioned in the parser by dragging them up or down in the list.

10. Excavator.dll: Runtime Display Contains:  Volume Bar on the left  Cut / Fill bar on the right  Reach bar on the bottom  Numeric values for the Reach, Depth and Channel  Vertical Red line is the Pontoon Protection  Below the Reach Bar is a display that lists all three sensor angles. If a sensor fails it will be listed here as Faulty.

12. Excavator in Action This is the display produced by excavator driver with bucket open, close and rotation.

13. Ancillary corrections Angle Sensors for Pitch and Roll Can use angle sensors for measuring pitch and roll to correct for water surface elevations as lever arms change Example here are two A2TS sensors A2Tsatt.dll
