New Grading Specific Features –New Machine Support –Rough Grade Control –John Deere Enhancements –New 2D Functionality
New Machine Support Caterpillar D7E Support –No machine specific tuning parameters required here Komatsu D155AX-6 (GPS only initially) –Machine specific tuning parameters required
Rough Grade Control Cat integrated feature - D7E only –Needs correct A4M1 firmware as well as V11.2 Not included in initial release of V11.2 – not quite enough testing has been completed here –A4M1 update –CD700 option key update Idea – operator has full control when the center of the blade is above design Auto controls (lift only) is only engaged when blade is on or below design Tilt is always controlled by the operator – to allow the for tilt steer capabilities Operator cannot push the center of the blade through the design – joystick cease to work –Float still works
Rough Grade Control Use cases –Bulk earth works – operator has full control to maximize earth moving without jeopardizing the design –Hybrid controls – maybe a good way to introduce this to a new operator
Rough Grade Control Select Grade Control Method from the Configuration Menu
Rough Grade Control Blade is below the design – the system is in Manual and the operator icon is shown Blade is on or below grade – the Auto icon is green and the operator icon is unfilled This indicates that autos are active and being used. Remember – center of blade auto guidance only here.
Rough Grade Control Auto button has been pressed but the center of the blade is above the design above – so operator is in control. Auto text is black and the operator icon is green The blade is below the design but the automatics are in an inactive auto state (due to some condition – e.g. the operator has just exited the Setup Menu.)
Rough Grade Control – Data Points When working in a fill situation the configured automatic control range limits is used (e.g. 0.2m / 0.8FT) When working in a cut situation autos are engaged when the A4M1 receives a lift the blade up command from the CD700. –Auto will continue to be used until any lower the blade down command is received from the operator – via the joystick. –This means that the blade will try and stick to the design (use both up and down automatics commands) until there is operator input.
Komatsu D155AX-6 Support Initially Dual GPS only Machine specific tuning parameters required Benefits: –Simpler and cheaper to install –Cleaner install –Trimble/Caterpillar now supports what Topcon does Which means we now cant be sold against by Topcon
Komatsu - D155AX-6 Support Important to know that the ECM on the machine may need to updated –Anything above S/N – 80206 (approx) –MUST be part number 7830-54-2005 or higher (could be -2007 or -2008). Number reported without dashes
John Deere Enhancements Auto / Manual indicator in the Test Valves screen No time out potential when in valve speed, valve calibrations and test valve screens Correct version of the ECM firmware is now shown in Diagnostics (introduced in V11.10B)
New 2D Functionality Reorganizing and modularizing the controls code for ease of future development (internal feature) –Used the CB420 controls algorithms for all 2D applications on dozers and graders Dozers – left / right blade tip mounting option Auto Tune capability for laser dozers Cross Coupling UI Optimized Valve Speed UI New Machine measurements New sensor softkey functionality on main screen allows existing v11.1 2D sensor combinations to be accessed more easily.
Blade Tip Mounted Masts No longer required to mount laser mast in the middle of the blade –Provides mounting flexibility –Provides more accuracy across the blade for a dual laser system Note – Blade Center and Right option is still available if required.
New 2D Sensor Softkey Functionality Sensor softkey shows the current sensor configuration Press to toggle through all combinations of 2D sensors detected New – all sensors detected are available in V11.2 V11.1 V11.2
Sensor Softkey Example – Dual Laser and Cross Slope System All these sensor combos… maybe user does not want them all at once
Shortcut on Sensor Softkey Press and hold the Sensor softkey for quick access to Vertical Guidance Method screen Shows all sensor combinations available Provides ability to limit sensor combos on Sensor softkey
Shortcut on Sensor Softkey Use the Tick / Cross softkey to select your favorite combos E.g. To only use Linked Dual Laser, Laser Left / Cross Slope Right, and Laser Right / Cross Slope Left
2D Sensor Combos Data Point 2D dozer with blade slope / mainfall / rotation sensor configured –Now gives Cross Slope guidance Before was Blade Slope guidance only
Auto Tune for Dozers Produces machine specific kPs / kDs for the sides of the blade controlled by any laser receiver - LR410 and SR300 (ala CB420) No support for graders – auto tune rarely used here
2D Controls Data Point Specific machine tuned values (.PSF files) for 2D systems will not be used in V11.2 –System uses the valve cal with default tuning values –Can auto tune laser configurations
Auto Tune - Dual LR410 Example Press to start initial search Press again to reverse search direction Press again to stop search Arrows define laser strikes Laser strike window goes green when strike requirements are met
New Machine Measurements New 2D controls algorithms on the CB430 require the A-frame length of the grader If this is not entered and you attempt to change the valve speed a message is posted
New Machine Measurements A-Frame length – where to measure? Locate a point at the front of the A-frameMeasure the distance from this point to the center of the hydra swivel joint as shown Center of the blades rotation
2D Valve Speed UI – Grader Left and Right Elevation valve speed is tied to left / right side of the machine Slope valve speed is used to speed up/slow down the slope control –Tracks the side that the slope control works on and is independent of the elevation valve speed Allows user to swap sensor combinations quickly without having to change valve speeds
2D / 3D Valve Speed Data Point Valve speed values are different between 2D and 3D configurations –Due to difference in 2D / 3D controls algorithms –Need to set values for both if swapping between 2D/3D modes
Cross Coupling UI Cross Coupling UI provided to replicate CB420 functionality What does it do? See next slides….
Explanation of Cross Coupling With Cross Coupling On, when elevation is corrected, the cylinder controlled by the Slope Sensor changes by the same amount as the cylinder controlled by the Elevation Sensor So when height is told to change, the cross slope side changes as well to keep cross slope true. Default setting and is used in most applications. Elevation Change Elevation controlled side Slope controlled side Start Position Halfway Position End Position
Explanation of Cross Coupling With Cross Coupling Off, the cylinder controlled by the Slope Sensor only reacts to the Slope Sensor So when height changes, the cross slope also changes until the Slope Sensor detects it and changes the Slope cylinder Good in hard cut situations. Elevation Change Elevation controlled side Slope controlled side Start Position Halfway Position End Position
