NOTICE
For the AccuGrade system to operate in automatic mode the E/H system may need to be set as installed by an Software Enabled Attachment (SEA). Refer to the machine price list for verification if an SEA is required. If an SEA is required refer to Special Instruction, REHS1238, "Obtaining Factory Password and Software Enabled Attachments".

Important Safety Information

Work safely. Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards.

The top banner of the display shows the text that is listed below:

"<- Auto Valve Calibration" - This message is displayed for auto calibration of the lift valve.

Only the information for the sensor that is being used in the calibration is displayed during the calibration. After selection, both the upper calibration and the lower calibration limits are displayed. The "OK/right reset" key (8) is used in order to continue the calibration. The "ESC/left reset" key (7) is used in order to abort the calibration. The activity indicator is animated in order to convey to the user that a sensor signal is available and that the calibration is in process, even if you do not observe any blade motion.

The user can press the "ESC/left reset" key (7) on any screen of the automatic valve calibration wizard to terminate the calibration that is in process. If the user is in the "Calibration Status" screen, this action shows the "Exit-Error" Screen, with the text "Abort". In all of the other screens, the user is returned to the "Valve Calibration" menu.

Procedure

1. Start the machine and allow the hydraulic oil to reach the normal operating temperature.

2. The engine speed should be set at high idle.

3. Set up a laser transmitter.

   Note: The tripod and the laser should be located at least 46 m (150 ft) away from the machine. The laser should be located in an area where the laser will not detect reflections or any light source that could disrupt the laser. Set the height of the tripod and the laser transmitter so that the laser beam will strike the laser receiver when the receiver is positioned correctly on the machine. Set the laser high enough so that the cab of the machine will not stop the laser beam from being detected by the laser receiver.

   Note: Avoid extending the electronic masts further than one-third of the total distance that the masts can be extended. This procedure will ensure a greater accuracy during calibration.

4. Raise the blade approximately 30 cm (12 inch) off the ground.

5. Press the menu key (6) .

Linked Elevation Calibration

A linked elevation calibration is necessary in order to measure and record the elevation difference between the right mast mount and the left mast mount. The AccuGrade system uses this measurement in order to compensate for the difference in height between the mast mounts.

The "Linked Elevation Calibration" menu is available only when the operating mode is configured as "Linked Elevation".

Note: A laser transmitter and a level are required in order to complete the linked elevation calibration.

Perform the following steps in order to complete the linked elevation calibration.

Show/hide table

Never look into a laser beam or point the beam into the eyes of other people. Set the laser at a height that prevents the beam from flashing directly into people's eyes.

1. Set up the laser transmitter so the laser beam is at a zero percent grade and a zero percent cross slope. Refer to the Operation and Maintenance Manual for the laser transmitter instructions on setting the grade and cross slope.

   Note: Caterpillar recommends the use of a laser transmitter with the following features: automatic self-leveling mode, 600 rpm min rotational speed and automatic out of level shutoff. Read the operator manual and follow the operator manual that is supplied with the laser transmitter. The tripod and the laser should be located at least 46 m (150 ft) away from the machine. The laser should be located in an area that the laser will not detect reflections or any light source that could disrupt the laser. Set the height of the tripod and the laser transmitter so that the laser beam will strike the laser receiver when the receiver is positioned correctly on the machine. Set the laser high enough so that the cab of the machine will not stop the laser beam from being detected by the laser receiver.

2. Ensure that the masts are at the lower limit.

   Note: Keep the height of the laser receivers as low as possible. This will help ensure greater system accuracy during calibration of the AccuGrade System.

   Crushing hazard! Read and understand the instructions and warnings in the Operation and Maintenance manual. Failure to follow the instructions or heed the warnings could cause serious injury or death.

   1. Raise the blade approximately 30 cm (12 inch). Ensure that there is enough room in order to use a level under the edge of the blade.

   2. Place blocks under the blade before checking the blade level.

"<- Auto Valve Calibration" - This message is displayed when the lift valve is calibrated.

"Auto Valve Calibration ->" - This message is displayed when the tilt valve is calibrated.

Only the information for the sensor that is used in the calibration is displayed during the calibration. After selection, both the upper calibration and the lower calibration limits are displayed. The "OK/right reset" key (8) is used in order to continue the calibration process. The "ESC/left reset" key (7) is used in order to abort the calibration process. The activity indicator is animated in order to convey to the user that a sensor signal is available and that the calibration is in progress even if you do not observe any blade motion.

The user can press the "ESC/left reset" key (7) on any screen of the Automatic Valve Calibration Wizard to terminate the calibration in progress. If the user is in the Calibration Status screen, this action shows the "Exit-Error" Screen, with the text "Abort". In all other screens, the user is returned to the "Valve Calibration" menu.

Procedure

1. Start the machine and allow the hydraulic oil to reach the normal operating temperature.

2. The engine speed should be set at high idle.
