Operating Modes
The Operating Mode that is configured determines the look of the Display. The Operating Mode also affects the operation of the buttons and switches on the Display. There are three Operating Modes.
Linked Elevation
Independent Elevation
Dual Cut/FillRefer to Operation and Maintenance Manual, "Configuration" in order to set the Operating Mode.Linked Elevation Mode
The following items describe the operation of the AccuGrade Laser System in Linked Elevation Mode:
Linked Elevation Mode only operates as a Dual Mast System. This mode requires only one reference elevation. This means that the blade is benchmarked over only one point. In Linked Elevation Mode, if either receiver is blocked, the valve drive module will prevent further drive to the hydraulic control valve (lift and tilt) until the blockage is removed.
The Display shows the reference elevation that is being worked toward.
You can toggle the "Right Mast Elevation/Menu Scroll" switch or the "Left Mast Elevation/Menu Scroll" switch in order to move both masts UPWARD or DOWNWARD by the same amount. This means that the same elevation offset is applied to both sides of the blade.
Press either the "ESC/Left Reset" button or "OK/Right Reset" button in order to start a search for the laser beam. If the left mast is over the benchmark, press the "ESC/Left Reset" button. The search for the laser beam stops when the left laser receiver is on-grade. If the right mast is over the benchmark, press the "OK/Right Reset" button. The search for the laser beam stops when the right laser receiver is on-grade.
The "Elevation Select" switch is inactive in Linked Elevation Mode. This means that both sides of the machine must use automatic mode or manual mode together.
The Linked Elevation Adjustment option is available in the "Configuration" Menu. Refer to Operation and Maintenance Manual, "Configuration" for more information.

The following items describe the operation of the AccuGrade - Laser System in Independent Elevation Mode:
Independent Elevation Mode requires the reference elevation for each mast to be set independently. This means that the blade must be benchmarked under the left mast and the right mast separately. Refer to Operation and Maintenance Manual, "Setting the Reference Elevation" for more information on the process that is used to benchmark the blade using Independent Elevation Mode.
The Display shows the two reference elevations that are being worked toward.
Toggle the "Left Mast Elevation/Menu Scroll" switch in order to move the left mast Upward or to move the left mast Downward. The elevation offset is applied only to the left side of the blade.
Toggle the "Right Mast Elevation/Menu Scroll" switch in order to move the right mast Upward or to move the right mast Downward. The elevation offset is applied only to the right side of the blade.Note: Using the joystick control
