Positive Slope - Right side of blade is higher than the left side of the blade (positive slope or zero). |
|
Negative Slope - Left side of blade is higher than the right side of the blade. |
|
Positive Mainfall - Machine is operating on positive or uphill grade. |
|
Negative Mainfall - Machine is operating on negative or downhill grade. |
|
Zero Mainfall - Machine is operating on zero grade. |
|
AUTO - The side of the screen where this icon is shown indicates the side of the blade that is under the control of the Cat GRADE with Cross Slope system. |
|
No AUTO - This icon is shown if there is a condition which renders automatic controls unavailable and the system is in the “Inactive Automatics” state. The icon will flash at a rate of two times per second. |
|
Manual - The side of the screen where this icon is shown indicates the side of the blade that was previously under the control of the Cat GRADE with Cross Slope system. |

| Illustration 17 | g06212575 |
“VALVE SPEED SETTING” - This setting determines how quickly the Auto side of the moldboard reacts. The factory default setting is 50% which is nominal for most applications and a good starting speed for new deliveries. However, as material type, particle size and surface quality changes, this setting can be adjusted for better performance. General rule of thumb is, the smoother and more consistent the material and/or surface, the faster the valve speed%. Typically, anything below 45% is too slow and anything above 70% is too fast.
When you scroll to this option, the display will show the current valve speed. The valve speed may be adjusted by pressing the up or down button. Press “OK” and use the “Return” soft key to exit Cross Slope Settings menu.
“OFFSET ADJUST” - This setting determines the amount of increment (increase) or decrement (decrease) adjustment for each time the thumb roller (1) is used to change the Target Slope Value. The factory default is 0.1%. Depending on the application, it might be more efficient to change this to 0.5% or 1.0%. For example, if you wanted to smoothly transition from a 4% crown slope to a 0% bridge approach slope or driveway, you might make the Offset Adjustment 1.0% to allow for a quicker transition as you use the thumb rollers (1) to change the Target Slope Value while operating in Auto mode.
When you scroll to this option, the display will show the current offset adjustment %. The offset adjustment % may be changed by pressing the up or down button. Press “OK” and use the “Return” soft key to exit Cross Slope Settings menu.
“NUMBER OF TARGETS” - This setting determines the number of targets available for preset values.
When you scroll to this option, scroll down to highlight the number of targets desired. Press “OK” and use the “Return” soft key to exit Cross Slope Settings menu.

- Center the circle under the frame.
- Side shift the blade until it is centered with the machine. This can be verified by measuring along the top of the blade on the left and right sides to the circle. When both distances are equal, the blade is centered in the side shift direction.
- Rotate the blade to 0 degrees of rotation.
Note: Ensure that the blade does not touch the ground during calibration.
Note: If conditions 2.a, 2.b, and 2.f have not been met, a warning message will display.
- To set the work tool lower limit, perform the following and press the "OK" button.
- Position the right side of the blade so that the blade slope angle is within range shown on the display.
- Press the "OK" button when the blade slope angle is in the correct range. Ensure that the right side of the blade is not touching the ground.
- To set the work tool upper limit, position the right side of the blade so that the blade slope angle is within the range shown on the display.
Note: The implement control lever must be in the "NEUTRAL" position before pressing the "OK" button.
Note: Do not move the left side of the blade when setting the upper limit. If the upper limit cannot be set without the left blade tip touching the ground, then restart the calibration and start with the blade raised higher above the ground.
- Prepare for automated calibration. Set the engine speed to high idle.
Note: For optimal calibration results, the engine should be running at high idle during the automated portion of the calibration. If the engine speed is not at high idle when the "OK" button is pressed, then a warning may be displayed. Set the engine speed to high idle and press the "OK" button again.
- Press and release the "AUTO/MANUAL" switch to begin the automated steps of the calibration. The right side of the blade will move automatically during the next four steps. The blade will begin to move slowly in the first automated step.

If the action alarm does not sound during this test or machine monitoring displays are not functioning, do not operate the machine until the cause has been corrected. Machine operation with faulty action alarms or displays could result in injury or death as any Warning Category 3 notifications will not be relayed to the operator. |
To ensure the proper operation of the Caterpillar Monitoring System, check the system daily.
The battery disconnect switch must be in the ON position.
When you turn the engine start switch from the OFF position to the ON position, the Caterpillar Monitoring System will perform an automatic self-diagnostic test.
The self-diagnostic test verifies that the outputs (gauges, alert indicators, and alarms) are operating correctly.
When you turn the engine start switch to the ON position, the following systems are tested for approximately one second: alert indicators, gauges, and LCD display.
The gauges must go to the far right positions. All alert indicators must come on momentarily. All segments of the LCD display must come on momentarily. The action alarm must sound.
The Monitoring System provides three warning categories. The first warning category requires machine system attention. The second warning category requires a change to machine operation or the performance of maintenance to the system. The third warning category requires immediate shutdown of the machine.
In this category, only the alert indicator comes on. This category alerts the operator that the machine system needs attention.
In this category, the alert indicator and the action light come on. This category requires a change in machine operation. The digital display area will display a message. If action is required, an instruction will be listed.
In this category, the alert indicator and the action light come on and the action alarm sounds at a steady rate.
This category requires an immediate change in machine operation. The digital display area will display a message.
In this category, the alert indicator and the action light come on and the action alarm sounds at a pulse rate.
This category requires immediate shutdown of the machine to prevent injury or death. This category requires immediate shutdown of the machine to prevent severe damage to the machine. The display will display a message. If action is required, the instruction will be listed.
Note: Do not operate the machine if the Monitoring System is not working or if the Monitoring System fails the self-diagnostic test at start-up. Stop the machine immediately if the following conditions occur:
- The alert indicator turns on.
- The action light indicator is flashing amber.
- The action alarm sounds at a pulse rate.
- The LCD Display is blank
Engage the parking brake and stop the engine. Investigate the cause of the problem.
Do not operate the machine until the cause of the problem has been corrected.
