• 3D-MC2 Parameters All measurements should be made as close as possible. Some

machines may be more difficult than other. Measurements +/- 1” you should be fine (Don’t be Lazy)

The machine should be parked on smooth level ground

• IMU Behind IMU Behind: Horizontal distance from the front most part of the

cutting edge to the MC2 arrow.

• IMU Inside IMU Inside: Horizontal distance from the right corner of the cutting

edge to the MC2 arrow.

• IMU Above IMU Above: Vertical distance from the cutting edge to the MC2

arrow.

• COR Inside Horizontal distance from the center of blade rotation to the right

side of the blade. COR=Center of Rotation (Tilt)

Machine Builder

• COR 6 Way Blade

Machine Builder

• COR Inside On 4 way blades or U-frame blades without a rotation or sloping

ball pivot, the COR will be a point opposite of the sloping cylinder and may be difficult to locate.

• COR 4Way Blade (U Frame)

Machine Builder

• COR Above Vertical distance from the center of blade rotation to the cutting

edge.

Machine Builder

• COR Above (5) Note* The Installation and Calibration Manual 7010-0924 Rev A describes the measurement incorrectly. It describes the COR measurement as the Vertical distance from the center of blade rotation to the MC2 arrow. The graphic is correct. (COR to Cutting edge)

MC2 Sensor Calibration

• MC2 Sensor Calibration The MC2 (IMU) sensor requires Blade Slope calibration and Mainfall

calibration. Both calibrations are accessed through the Slope Control Key.

MC2 Sensor Calibration

• Calibrating Blade Slope Calibrating the Slope Sensor is preformed by placing the blade at a

know slope and entering that information into the control box.

Note* The procedure in the manual shows calibrating the blade with a slope to ensure the proper +/- sign

MC2 Sensor Calibration

• Calibrating Mainfall Slope Place the machine on a uniform surface so that both the tracks

and the blade are on the same surface, make sure the blade is flat on the ground and square to the machine.

Measure the mainfall slope of the pad and enter that number as the Mainfall slope. Be sure to turn the machine around and confirm the calibration is correct. It should read exactly opposite assuming the ground is smooth.

MC2 Sensor Calibration

• Calibrating Mainfall Slope The Mainfall Calibration is extremely important to the overall

performance of the machine when working slopes.

Blade Wear

• Blade Wear As the cutting edge wears the mainfall calibration will become

incorrect causing elevation errors especially on steep slopes, since the mainfall calibration is responsible for determining mast tilt when traveling up and down hills it is important to maintain a proper calibration.

Periodic adjustment (recalibration) will be required as the blade wears.

MC2 Sensor Calibration

• Calibrating Mainfall Slope The procedure to Adjust Mast Angle in the Installation and

Calibration Manual 7010-0924 Rev A. Will be removed from the manual since this procedure should have been already preformed when installing the pole mount.

Valve Offsets

• Setting Valve Offsets Valve Offsets should be set so that the blade just begins to move.

Do not set artificially large values as is sometimes typical in standard 3D control.

Gains

• Setting Gains Due to the nature of 3D-MC2 Gains can typically be set higher than

with standard 3d system. Elevation and Slope Gains should be set to the highest setting

without the system becoming over reactive and unstable. Test individually by switching to manual and placing the blade in a

course correction then switch to auto. Keep increasing the gains individually until you reach the highest setting still maintaining stable control with the blade in the air. Small adjustment may need to be made once the machine is in the dirt.

Side Slopes

• Side Slopes Slower operating speed (As Slope increases speed decreases)

3-1 or Greater Eliminate Blade Rotation (Blade Parallel to slope)

IMU Compass will compensate for rotation (Future)
