Illustration 2	g00393679

The Machine Performance Panel is equipped with three touch pads (1), (2), and (3). Also, the Machine Performance Panel has the following three operating modes: display, calibration and machine configuration. The three switches can have multiple functions. This depends on the function that is displayed and the operating mode that has been selected for the Machine Performance Panel.

The following items are displayed in metric units or US units: length, area and speed. The Machine Performance Panel is available in a metric version. Also, the Machine Performance Panel is available in a version that displays US units. The version can be determined by changing to the ground speed mode. See "Monitoring Functions" for more information. The Machine Performance Panel will display "km/h" on the right side of the LCD if the display is the metric version.

Monitoring Functions

Illustration 3	g00393681

Seven functions can be displayed on the Machine Performance Panel. The operator can select a function for display by moving the arrow on the lower portion of the LCD display. Use the left touch pad and the center touch pad in order to move the arrow to the desired position.

When the arrow is located above a symbol, that function is displayed on the four digit LCD display. The arrow will scroll to the left or to the right of the position that is shown by pressing once on the left touch pad or the center touch pad.

Powerup Sequence - When the Machine Performance Panel receives power, a self-test is performed on all the LCD segments. The self-test turns on all the LCD segments for 1 second. Next, the engine hours are displayed for 3 seconds. The Machine Performance Panel will then default to the display for the engine rpm speed.

Note: The Machine Performance Panel only displays the operating hours that were accumulated since the installation of the Machine Performance Panel. If a new Machine Performance Panel has been installed, the total operating hours that are displayed on the Machine Performance Panel may not match the total operating hours that are displayed on the optional Challenger Information Display.

Engine RPM Speed (4) - The display indicates the engine rpm speed. The engine rpm speed is always displayed on the bar graph at the top of the display once the engine speed reaches 1250 rpm. The recommended working range is 1800 rpm to 2100 rpm. The working range is indicated by a dark green region.

The engine rpm speed may also be displayed on the LCD display. In order to display the engine rpm speed, locate the arrow above the symbol for engine rpm speed. This will display a more accurate engine rpm speed. Engine rpm speed that is less than 493 rpm is displayed as zero.

Note: The engine rpm speed that is displayed on the Machine Performance Panel can vary up to ten rpm from the engine rpm speed that is displayed on the optional Challenger Information Display.

Engine Hours (6) - This display indicates the total number of hours that the engine has operated. If the engine rpm speed is greater than 200 rpm, engine hours are accumulated and stored in permanent memory. The Machine Performance Panel is capable of displaying up to 9999 hours.

Note: The Machine Performance Panel only displays the operating hours that were accumulated since the installation of the Machine Performance Panel. The total operating hours that are displayed on the Machine Performance Panel may not match the total operating hours that are displayed on the optional Challenger Information Display.

PTO Speed (5) - This display indicates the rotational speed of the power take-off. The PTO speed is displayed in rpm. The PTO speed is obtained by multiplying the engine rpm speed by the gear ratio for the PTO. The display will show a calculated value for the speed of the PTO even when the PTO is not engaged. The PTO speed is derived strictly from the engine rpm speed.

Machine Ground Speed (8) - The display indicates the true ground speed by use of a ground speed sensor. The ground speed can be displayed in either mph or km/h. The minimum speed that can be displayed is 1.6 km/h (1.0 mph). In order to achieve the most accurate ground speed, a calibration for distance must be performed. This is done in order to adjust the system for possible electrical tolerances or mechanical tolerances. See "Usage of the Accumulated Area Function" for more information.

Note: An incorrect calibration for distance can cause the values for ground speed to be incorrect. An incorrect calibration can also cause the value to be a zero.

Note: The value for ground speed that is displayed by the Machine Performance Panel may differ from the value that is displayed by the optional Challenger Information Display. The Challenger Information Display only measures the speed of the track. Also, the Challenger Information Display does not compensate for track slippage. The Machine Performance Panel will compensate for track slippage.

Track Slip (9) - The display indicates the percent of track slip. The value is based on the comparison of the true ground speed and the speed of the track. The range of values for track slip is 0 percent to 100 percent. The measurement of slip does not begin until the machine is moving at least 1.6 km/h (1.0 mph).

Calibration for Track Slip - The Machine Performance Panel must be calibrated in order to ensure that the correct values for track slippage are displayed. This may be done by operating the machine without a load on a level surface that is firm. Make sure that a constant speed is maintained while the machine is driven straight ahead. Next, locate the arrow over the symbol for slip (9) and hold the right touch pad down for three seconds. The display should show a "0" and the display should flash once when the calibration is complete. The calibration procedure will zero the track slip for no-load conditions. Also, the calibration procedure compensates for possible electrical tolerances or mechanical tolerances.

Note: If calibration for track slippage is performed under loaded conditions, the value for track slippage is not accurate. During the calibration procedure, the machine must be operated on a level surface that is firm. Also, operate the machine at a constant speed in a straight line. Otherwise, the calibrated value for track slippage is not accurate.

Total Accumulated Area (7) - The display indicates the total area that the machine has worked. The total area is based on the distance that is covered and the width of the implement. The total area is stored in permanent memory. The version of the Machine Performance Panel determines whether the total area is measured in hectares or in acres.

Starting or stopping the following functions can be done by two methods: total accumulated area and area per hour. A manual method and an automatic method is available.

Manual - Locate the arrow over the symbol for the total accumulated area and press the right touch pad once. This will start the recording process. Press the right touch pad again in order to stop the recording process. When the function is stopped, the value for the current total accumulated area will flash continuously. In order to reactivate the recording process, press the right touch pad again.

If you are unable to reactivate the recording process, the shorting plug for the two-pin connector is not installed or the shorting plug is not functioning properly. The two-pin connector is located at the rear of the machine.

Note: If a power interruption occurs during machine operation, the Machine Performance Panel stops the recording process. The values are not lost. In order to start the recording process again, locate the arrow over the symbol for the total accumulated area and press the right touch pad.

Automatic - An implement status switch will automatically start the following functions: total accumulated area and area per hour. An implement status switch will automatically stop the following functions: total accumulated area and area per hour. A raised implement stops the recording process. A lowered implement reactivates the recording process. Initial activation must use the manual method. Once the recording process is activated manually, the automatic method will proceed.

If an implement status switch is not used, a shorting plug must be installed in the two-pin connector in order for the manual mode to function. The two-pin connector is located near the connector for the trailer.

Usage of the Accumulated Area Function

The Machine Performance Panel must be calibrated to the machine and the implement prior to using the following functions: total accumulated area and area per hour. The calibration is performed by use of the following steps:

• Verify or set the width of the implement.

• Verify or set the distance calibration factor.

• Reset the total accumulated area to zero.

The following procedure is necessary in order to calibrate the total accumulated area.

Width of the Implement "b1" - In order for the Machine Performance Panel to correctly calculate the total hectares or acres, the width of the implement must be known. In order to set the width of the implement, use the following procedure:

1. Press the left touch pad for four seconds and release. A "dC1" should now be displayed.

2. Press the left touch pad repeatedly in order to scroll until "b1" is displayed.

3. Press the center touch pad once in order to display the current value for the width of the implement "b1". The width of the implement is measured in either meters or feet.

4. If the width of the implement is correct, go to Step 7.

5. If the width of the implement is not correct, change the value by pressing the center touch pad. This will select the digit that needs to be changed. This digit should be flashing. Press the right touch pad in order to change the digit to the desired value.

   Note: If the center touch pad is held down for more than three seconds, the decimal point begins to cycle from the right to the left. This feature may be used in order to set the Machine Performance Panel for small implements or large implements.

6. Repeat Step 5 on all digits until the width of the implement is set.

7. Press the left touch pad in order to save the value.

8. Press the left touch pad for four seconds in order to exit the calibration mode. The arrow will return to the display. This indicates that the Machine Performance panel is back in the display mode.

Distance Calibration Factor - This factor is used to calculate the following functions: machine ground speed, total accumulated area and area per hour. The following two methods can be used in order to set the distance calibration factor: Measured "dC1" and Calculated "dC2". Each method is described below. Only one method needs to be used. Either method will set both the "dC1" and "dC2" to the same values. This only needs to be done once, unless a new Machine Performance Panel is installed. Also, the installation or relocation of a ground speed sensor will require the distance calibration factor to be reset.

The measured "dC1" method is the most accurate method in order to set the distance calibration factor. This method provides the best estimate for the total accumulated area and the area per hour.

In order to begin the calibration procedure, lay out a 152 m (500 ft) course that is straight and level. Place a marker at each end. Position the machine 9 to 15 m (30 to 50 ft) behind the first marker. Place the Machine Performance Panel in the calibration mode by pressing the left touch pad for four seconds. Use the left touch pad in order to scroll until "dC1" is displayed. This is the identifier for the distance calibration factor. Press the center touch pad in order to display the current distance calibration factor. The display should now be flashing.

Start moving the machine through the course. Use a combination of engine rpm speed and a gear ratio that will provide a ground speed of at least 1.6 km/h (1.0 mph). The machine must travel in a straight line. As the first marker is passed, press and release the "Start/Stop/Reset" switch in order to start the procedure. The number on the display begins to count upward from zero.

When the machine reaches the second marker, press and release the "Start/Stop/Reset" switch again. The display stops counting and the new number that is displayed is the distance calibration factor. In order to save the value into memory, press the left touch pad for four seconds. The Machine Performance Panel returns to the normal display mode.

The calculated method "dC2" is the less accurate method. The calculated method may be used if the measured method "dC1" is not practical or available. In order to set the calculated distance calibration factor "dC2", use the following procedure:

1. Press the left touch pad for four seconds and release. A "dC1" should be displayed.

2. Press the left touch pad once. A "dC2" should be displayed.

3. Press the center touch pad in order to display the current distance calibration factor.

4. If the value is equal to 30.14 for the version in US units, go to Step 7. If the value is equal to 98.89 for the metric version, go to Step 7.

5. If the value is not correct, change the value by pressing the center touch pad. This will select the digit that needs to be changed. This digit should be flashing. Press the right touch pad in order to change the digit to the desired value.

   Note: If the center touch pad is pressed for more than three seconds, the decimal point begins to cycle from the right to the left. If this occurs, press and release the center touch pad until the decimal point returns to the proper position.

6. Repeat Step 5 on all digits until the distance calibration factor is set.

7. Press the left touch pad in order to save the distance calibration factor.

8. Press the left touch pad for four seconds in order to exit calibration mode. The arrow will return to the display. This indicates that the Machine Performance panel is back in the display mode.

When "dC1" is set by the measured method, the Machine Performance Panel also stores the value in "dC2". Conversely, if "dC2" is set by the manual method, the Machine Performance Panel also stores the value in "dC1". The values will be identical. The only difference between the values is the method that is used in order to enter the values.

Reset the Total Accumulated Area to Zero - This step must be done in order to erase previous data that is contained in the Machine Performance Panel. This is done in order to return the total accumulated area and the area per hour to zero when you change fields.

Use the following procedure in order to reset the following functions: total accumulated area and area per hour.

1. Move the arrow to the total accumulated area (6) by pressing the left touch pad or the center touch pad.

2. If zero is displayed, the total accumulated area is already reset. No further action is required.

3. If the display does not show a zero, press and hold the right touch pad for three seconds. The display should show a zero.

The Machine Performance Panel is now ready to use the functions of total accumulated area and area per hour.

Illustration 6	g00393841

Area Per Hour (10) - The display indicates the area that is covered per hour of operation. This function does not work unless the function of total accumulated area is enabled. The version of the Machine Performance Panel determines whether the area is measured in hectares or in acres.

The Machine Performance Panel uses the ground speed and the width of the implement in order to calculate an estimate of area per hour. A constant ground speed should be maintained. A change in ground speed or a change in the width of the implement will change the value.

The function of area per hour is displayed only if the total accumulated area is enabled. The total accumulated area is enabled when one of the following conditions are met:

• A touch pad is pressed.

• An implement status switch is closed.

• A shorting plug is installed if the implement status switch is not used.

If the total accumulated area is disabled, the area per hour will display a 0. The area per hour and total accumulated area can be activated manually. Also, the functions can be activated by use of an implement status switch.

Illustration 7	g00464494

If an implement status switch is not used, a shorting plug must be installed in the two-pin connector. The two-pin connector is located on the wire harness near the trailer connector.

Note: It is not possible to only enable the area per hour. In order for the area per hour to display a value, the function for the total accumulated area must be activated.
