Functional Test

The Cat Monitoring System performs an automatic internal test when the engine start switch is moved from the OFF position to the ON position. The test verifies proper operation of the outputs (displays, alert indicators, and the action alarm) and the internal circuits. The operator must observe the displays in order to determine whether the monitoring system is operating properly. The length of time for the test is approximately 3 seconds.

1. During this test the action alarm sounds once.

2. All of the indicators will illuminate and the indicators will switch colors, if supported.

3. All of the pixels in the digital display window will turn on.

4. All of the gauge needles will sweep smoothly from left to right over the duration of the test.

5. The display then goes into Normal Mode of operation.

Performance Pages

Illustration 5	g03657287
Performance Page

The performance pages on the monitoring system are the main introductory pages. Real-time machine status information is displayed on the performance page.

Categories for the navigation buttons are displayed on the right-hand side of the performance page.

Top Level Navigation

Right-hand Side Navigation Buttons

The Information Display has five buttons that act as the principle navigation. The Display buttons have an icon and are located on the right-hand side of the Display. The right-hand side buttons are considered the categories for navigation.

Display - Press the display button in order to view the display menu.

Machine - Press the machine button in order to view the machine menu.

Totals - Press the totals button in order to view the totals menu.

Service - Press the service button in order to view the service menu.

Operator - Press the operator button in order to view the operator menu.

Menu Navigation Buttons

At the selection of a category, a menu appears and the right-hand side buttons change to navigation buttons. While in the submenus, the right-hand buttons are displayed as the navigation keys for the category selected. In this state, the right-hand side buttons are "Up", "OK", "Down", "Back", and "Home".

Up - The "Up" navigation button navigates lists and menus in the upward direction.

OK - The "OK" button selects a highlighted item, and confirms an action.

Down - The "Down" navigation button navigates lists and menus in the downward direction.

Back - The "Back" button navigates to the previous screen, and cancels an action.

Home - The "Home" button navigates to the default screen from anywhere within the Display.

Menu Buttons and Menu Button Groups

Navigation through menu lists and submenus is possible by using the menu button groups. Menu buttons do not show a pressed state. Instead, menu buttons highlight in yellow when the operator selects an item. A menu button group is accessible by directly touching a single button within the group, or by using the navigation buttons along the right side. To select the highlighted item, press or touch the "OK" button. On certain machines, if more than four options are available and appear in a menu button group, a non-interactive scroll bar will appear.

Scroll Bar

Illustration 6	g03377932
A three page scroll bar on page 1.

Illustration 7	g03377990
A three page scroll bar on page 2.

The scroll bar object is used to navigate between the main performance pages. The scroll bar is distinguished from the non-interactive scroll bar by using an image to show the button characteristic in yellow. The scroll bar slider is also visually wider and has an expanded activation zone to reduce activation error. This scroll bar slider brings the next page into view with either a touch above or below the slider or a directional drag of the slider. Arrows appear on the slider bar when more pages are available above or below.

Incremental Bars

Cat Compaction Control improves productivity on a jobsite by providing the operator an indication of soil stiffness as the machine is working, and it enables the operator to determine the amount of compaction necessary for the job. Cat Compaction Control is accessible using the scroll bar on the performance page to access the Cat Compaction Control screen.

The Cat Compaction Control feature determines the Machine Drive Power (MDP) value (1). MDP is a calculation of the rolling resistance of the machine in the material being compacted. As the operator compacts the material, the real-time MPD Value (1) changes as the machine moves over the material. The real-time MDP Value (1) is a unit less number between 0 and 150, where 0 represents a soft or uncompacted material and 150 represents a stiff or compacted material. The real-time MDP Value (1) changes as the soil is compacted, indicating when the machine is no longer increasing the stiffness/compaction of the material.

The Cat Compaction Control Screen allows the operator to enter a target MDP Value (5) for the material being compacted. The target MDP Value (5) can be determined in the following ways:

Test Strip Comparison - Construct a test strip with a representative material, layer thickness, and moisture content. Establish a rolling pattern and compact the test strip at expected production levels. The compactor has achieved maximum compaction once the real-time MDP Value (1) changes less than ±5 units between passes for the given soil conditions. Note the MDP value (1).

Point Comparison - Choose a properly compacted area on the worksite that has been measured with a traditional compaction measurement system. Run the machine over this area, and note the real-time MDP Values (1). After determining a Target MDP Value (5), the value can be entered with the aid of an on-screen keypad. The keypad is accessed by touching the MDP Target Icon (4). Enter the MDP target value by tapping the appropriate numbers on the On-screen Keypad (7) then tap the OK Button (8). The screen returns to the Cat Compaction Control screen, and this value appears as the Target MDP Value.

The Sliding Scale (6) contains a Sliding Bar (2). This is a visual representation of the progress of the real-time MDP Value (1) towards the MDP Target Value (5). The green Acceptance Zone (3) within the Sliding Scale (6) represents 90% to 130% of the displayed MDP Target Value. This visual representation allows the operator to determine if the real-time MDP Value is near the MDP Target Value. Historic testing and evaluation have determined that an MDP value at or above 90% of a valid target value is an indication that the machine is no longer substantially affecting the compaction of the material. The operator can then move to another area or place another lift.

The following operating conditions must be met for the system to display a real-time MDP Value. The real-time MDP value and the sliding bar will be functional during the following conditions of operation:

• Machine gear must be in 1F/2F or 1R/2R

• Throttle must be greater than 90%

• The grade must be less than a 6 degree incline

Note: If the operation conditions are not met the MDP value will be displayed as "***" and the sliding scale will not function.

Warning Categories

The Caterpillar Monitoring System notifies the operator of an immediate problem with a machine system or an impending problem with a machine system. The Caterpillar Monitoring System provides four warning categories. The categories are based on the severity of the problem. The categories dictate the required response of the operator.

Table 2
