- shutting down
- placing the control in the configuration mode
- saving the values in the control's EEPROM
- resetting the control
The programmable values can be loaded and the programmable values can be downloaded. The programmable values can also be saved to a file. A window is provided for the real time monitoring. A window is provided for the programming of all parameters of the control and the values of the control. Custom windows can easily be created and saved. Each of the windows can display 28 lines of monitoring and programming parameters without scrolling. The number with scrolling is unlimited. Two windows can be open simultaneously to display up to 56 parameters without scrolling. Programmable values can be changed at the window.
The Watch Window communicates with the control through the J2 port. With the control's default settings, the control communicates using RS-232 at 19200 baud. A standard null modem cable is needed to connect a personal computer to the J2 port. The RS-422 cable may be needed in noisy environments. The RS-422 cable may also be needed over long distances. When the RS-422 cable is needed, refer to the section in this Service Manual"Serial Communication Port Wiring" for serial port wiring.
The J1 port is configured for a programmer. The J1 port may be temporarily configured as a ServLink port. This configuration can be done in the "Communications" menu. When the J1 port is configured as a ServLink port, a 180-3760 Cable is used in order to connect a personal computer to the J1 port. The RS-232 signals that come from the personal computer are converted into RS-422 signals by the cable. Power for the converter is provided from the J1 port through the cable.
Control View PC Interface
The Control View PC Interface is a ServLink user which has all of the programmable values and monitoring parameters for the control.
This interface connects directly to the values of the control and to the parameters. The parameters are updated very fast. The adjustable values may be changed directly and the values can be saved. The values can be saved to the EEPROM of the controller or the values can be saved to a file that can be loaded or downloaded.
The Control View communicates with the control through the J2 port. The J2 port is configured as a ServLink port. The Control View requires a widely available null modem cable. The cable that is used can be found at most stores that deal with electronics or computers.
The J1 port is configured for a programmer. The J1 port may be temporarily configured as a ServLink port. To configure the port, use the "Communications" service menu. This configuration can be used for the Watch Window or for Control View. When the J1 port is configured as a ServLink port, a 180-3760 Cable is used in order to connect a personal computer to the J1 port. The RS-232 signals that come from the personal computer are converted into RS-422 signals by the cable. Power for the converter is provided from the J1 port through the cable.
To display the part number and the revision of the software for the controls, see the "Help About" topic. Refer to this part number and the revision level for any consultations regarding the control. Read the book "Getting Started" that is included with the Control View installation of the software.
System Requirements
- Any of the following operating systems can be used: Windows 95, Windows 98 and Windows NT 4.0.
- The processor must be at least a Pentium with 166 mHz or an equivalent speed.
- The minimum requirement for the RAM is 8 mega bytes. For Windows 95, 32 mega bytes are recommended. For Windows NT 4.0, 64 mega bytes are recommended.
- At least one free port is required for communications.
Control Modes
 | |
| Illustration 1 | g00672516 |
"Service Mode" - When the controller is active, the controller is in the service mode. While you are in the service mode, the values that are configured can not be changed and the values that are programmed can only be changed within ten percent of the value per single adjustment.
"Configuration Mode" - This mode is used in order to set up options that cannot be changed while the controller is active. Switching to the configuration mode will cause a lockout of the input and the output. The lockout is a safety precaution, that is used to make sure that the engine is shut down prior to changing settings that are configured. Verification is needed so that the control is not accidentally placed in configuration mode.
 | |
| Illustration 2 | g00672520 |
The "Enable Switch to Configuration Mode" must be checked in order to enter the "Configuration Mode". Then press on the button or click on the button that is marked "Configuration Mode" in order to enter "Configuration Mode". Click on the "X" in order to close the window. Click on the "X" in order to cancel the window.
"Show Service Values" - This item will display the values at the top in order to adjust the values. If the control is in "Configuration Mode", then the values can be adjusted by any amount within the maximum and the minimum ranges. When the control is in the "Configuration Mode", the ranges can be adjusted by more than ten percent.
"Show Configuration Values" - This option will make the "Configuration Values" visible. This option is useful in verifying the settings when you are operating in the "Service Mode". If an attempt to change a "Configuration Value" is made during "Service Mode" operation, an error will be generated. The error will indicate that this function is not allowed.
| NOTICE |
|---|
When the control is in the configuration mode, no other inputs or outputs are processed. If the control is placed in the configuration mode during engine operation, the results could be unpredictable. Always shut the engine down before the control is placed in the configuration mode. |
Startup Screen
The Startup Screen that is shown in Illustration 3 appears when the Control View interface has been opened.
 | |
| Illustration 3 | g00672523 |
The "Monitor Shutdown" screen is shown. This screen will display the current status of all shutdowns. An "Alarm Reset" button is provided in order to reset any alarms. The "Alarm Reset" button is provided in order to reset any shutdowns that have been cleared.
The tabs that are at the top of the screen describe the main screens. In order to move to another screen, click on the appropriate tab. Some screens have an arrow in the upper right hand corner. The arrows are used to scroll to other tabs that may be hidden. Some screens will display additional tabs for other screens. Clicking on these tabs will move you into another screen.
Click the right button anywhere on the tab sheet except a gauge display. This will move you quickly to another screen. The main list of tabs will appear. Also, an arrow will appear at the right edge of the main lists which contain further lists. This facilitates movement to other screens. To display a particular screen, left click when the cursor is over the desired screen.
Illustration 4 is an example of right clicking in order to select the "Fuel Limiters" screen. Illustration 4 also shows an example of right clicking in order to move from the "Fuel Limiter" screen to the "Pressure Gauges" screen. The "Pressure Gauges" screen can be selected from either the "Monitor" menu or the "Control Mode" menu. Illustration 4 also displays other options that can be reached through the "Monitor" screens and the "Main" screens.
 | |
| Illustration 4 | g00672524 |
The "Fuel Limiter" screen is typical of all screens except for screens that show the curves. The "Fuel Limiter" screen includes the following displays:
- Analog displays of the "Engine Speed" and the "Fuel Demand"
- Digital displays of the "Engine Speed" and the "Fuel Demand"
- LED display of the "Fuel Limiter In Control"
- The bar graph displays the fuel limits on the LSS Bus.
Lower tabs for these items are shown:
- "Fuel Limiter Settings"
- "Torque Limit Curve"
- "AMP Limit Curve"
The "Fuel Limiter" tab is displayed in Illustration 4.
Each set of programmable values has two sets of raise/lower arrows. The set points can be adjusted by clicking on the arrows. The hollow arrows adjust the set points slowly and the solid arrows adjust the set points quickly. The set points may be entered by highlighting the value and by typing the value directly. The arrows for raising and lowering of the value will be replaced by an "=" sign. In the service mode, the value that is entered must be within ten percent of the previous value in order to be accepted. This rule does not occur in the "Configuration Mode". Enter the new values into the system by clicking on the "=" sign or by pressing the enter key. All the values in either mode must be within the limits that are programmed into the control software.
Illustration 5 is the same "Fuel Limiter" screen without the optional screens that can be selected by right clicking. The tabs in the lower part of the "Fuel Limiters" screen display the values that are programmed and arrows that can be used for adjusting values.
 | |
| Illustration 5 | g00672525 |
Right clicking on a gauge panel will bring up a different quick menu.
 | |
| Illustration 6 | g00672528 |
This quick menu will appear when you right click on a gauge that has an adjustable range. There are always multiple quick options and a manual option. If the program is set to save settings on close, then new gauge settings will automatically be saved when the program is closed.
Saving Settings
 | |
| Illustration 7 | g00672534 |
Use the following procedure in order to save the settings of the gauge and the position of the screen when you exit:
- Click on the "Options" button.
- Click on the "Save Settings on Exit" button.
The "Reset to Default Settings" is the other option that is under the "Options" list. The "Reset to Default Settings" will reset all of the options of the user to the default values.
The settings of the Control and the settings of the Program at any time can be saved from the "File" menu.
 | |
| Illustration 8 | g00672535 |
When "File" is selected, the following choices will be available:
- The "Save Settings Now" will save the position of the screen and the settings of the gauge.
- The "Save to EEPROM" will save the programs in the control's EEPROM.
- The "Load Config File" will load settings from a saved "Configuration File" into the control's EEPROM. This will override all of the previous values. The control must be in the configuration mode in order to perform this function.
- The "Save As Config File" will dump all of the settings from the control's EEPROM into a "Configuration File".
| NOTICE |
|---|
To prevent possible damage to the engine resulting from improper control settings, make sure you save the set points before removing power from the control. Failure to save the set points before removing power from the control causes them to revert to the previously saved settings. |
2D Curves
The 2D curve screens are unique. The Torque Limit Curve screen that has the values and the raise/lower arrows was shown earlier on the "Fuel Limiter" screen. Illustration 9 shows a different way of viewing and changing this same curve as a graph. This view is shown instead of settings that have been calculated .
Perform the following procedure in order to view a curve:
- Click on the "Graphs" tab.
- Click on the desired curve.
The "AMP Fuel Limit" and the "Torque Fuel Limit" will be the curves that will appear on the list.
 | |
| Illustration 9 | g00672536 |
The Torque Limit Curve screen that is shown in Illustration 10 is available for viewing the graph. This is available for changing the set points of the curve.
 | |
| Illustration 10 | g00672537 |
Illustration 10 shows that the Torque Limit Curve is a 2D curve with five breakpoints. The Torque Limit Curve is set to limit torque by limiting the demand for fuel at various engine speeds. A digital display of the present "X" and "Y" values in engineering units is included. The "X" will represent the curve's input and the "Y" will represent the curve's output. "Y" in this example is the fuel limit that is based on engine speed. "X" is engine speed.
Holding the cursor over a curve breakpoint will display the coordinates. The coordinates will be displayed in the X, Y format. This is shown in Illustration 11.
 | |
| Illustration 11 | g00672540 |
Right clicking on a breakpoint and selecting "properties" will bring up a "Point Adjustment" window for the point that has been selected. This is shown in Illustration 12.
 | |
| Illustration 12 | g00673761 |
Adjustments to both the "X" and the "Y" values can be made. The values can be adjusted for the selected point by using the raise/lower arrows or by typing in values and by pressing the "=" key. All breakpoints of all the curves can be adjusted in this manner through the curve graph screens.
The setup of the dialog box for the 2D axes and for the colors of the graph are shown in Illustration 13.

| Illustration 13 | g00673764 |
Trends
 | |
| Illustration 14 | g00674272 |
The Trend Graph provides a visual representation of data that changes over time. This is especially useful for programming an engine and for analyzing different fluctuations.
 | |
| Illustration 15 | g00674275 |
Illustration 15 is an example of analog inputs as well as a static value. | |
The Available Trends include "Speed Dynamics" and "Pressure Trend".
Speed Dynamics - This feature includes these parameters: Engine Speed, Speed Reference, Percentage of Fuel Demand, Remote Speed Reference and Torsional Level.
Pressure Trend - This feature includes these parameters: Percentage of Fuel Demand, Inlet Manifold Pressure, Oil Pressure and Water Pressure.
The parameters are referred to as "Trend Pens" for graphing purposes.
Reading and Use a Trend Graph
The Trend Graph includes the following features:
- A Quick Menu with different options will appear by right clicking anywhere on the graph.
- A Trend Pen axis will be shown on the left of the screen by left clicking on the description. Individual axes are available because different values need to be graphed on different ranges.
 | |
| Illustration 16 | g00674276 |
The axis provides the maximum values and the minimum values of the respective pen. This is indicated by two marks on the right side of the axis. The program will zero the values when the program is first started. The "Max" and "Min" values may need to be reset once the program is running. This is accomplished by right clicking on the graph. Then, select the "Max and the Min Values" and then selecting "Reset All Max and Min".
Auto Update - This feature enables the user to perform the following functions:
- Stop the motion of the graph.
- Resume the motion of the graph.
- Stop the logging of the files.
- Resume the logging of the files.
Auto Save Settings - If this function is checked, this function will automatically save all settings as the settings are changed.
Copy to Clipboard - This function will copy the whole graph to the clipboard so that the graph can be pasted into any other Windows application that is capable of receiving a bitmap file from the clipboard. This function will copy the following items: axes, the graph of the window, descriptions and values.
Log to File - Clicking on this function will enable logging or this function will disable logging. Note that trying to start the logging will have no effect if no file for logging is specified. This feature is provided if a history is needed. Information is logged on every update in a file. The file is saved in an "ASCII" format. Data is automatically added to the end of a file. If you wish to start a new log, enter a new name for the file. The file of the log can be changed in the configuration dialog. The data is added only to the end of the file. The file will be automatically created when logging is started.
Illustration 17 is a example of a log that is generated from the trend. Less than three seconds of time is shown in this example.
 | |
| Illustration 17 | g00674278 |
Log Status - This function will show a screen with estimated values that will indicate the amount of data that is being logged for the following time periods: each second, each minute and each hour. This function is useful if you wish to have a file of logging that is kept for a longer period of time and if you want to make sure that you do not run out of space on a disk. The estimate is based on writing every value at the Maximum Axis Value. If logging the time is enabled, then every "Time Stamp" is evaluated as having three decimal places for estimating purposes.

Properties
Illustration 19 shows the "Properties" windows.
 | |
| Illustration 19 | g00674538 |
The "Properties" window will enable the operator to adjust the following features:
Pen Status - This function will enable the graph or this function will disable the graph of data for that pen. This is useful if pens are overlapping or only certain values need to be monitored or logged.
"Color" - Change the color of the trace of the pen. This function is useful for maintaining the contrast.
"Line" - This function is useful for maintaining contrast. However, if the duration of the update and the length of the graph only moves a couple of spaces, then the style does not appear to be affected. This occurs because each of the segments that are drawn are not long enough to show a complete cycle in the line.
"Minimum" - This value is used in conjunction with "Maximum".
"Maximum" - These values are used in order to organize information that is used in the graph. Change these values in order to move in or move out on a particular region for a given Pen.
"Show Time" - This function toggles in order to display the duration of the graph. The time can be written to the top of the graph or the bottom of the graph.
"Show Grid" - This function toggles in order to obscure the grid or this function toggles in order to display the grid.
"X Grid Tics" - This function controls the amount of lines that are drawn parallel to the "Y Axis". Note that this value is not exact, but used in order to generate the grid density. Change the grid density to a high value or to a low value and note the results in order to understand this function.
"Y Grid Tics" - This function controls the amount of lines that are drawn parallel to the "X Axis". This also controls the amount of marks that are placed on the "Y Axis".
"Decimals" - This function controls the amount of decimal places that are shown for all data that is displayed on the graph. This also controls the amount of decimal places that are used when data is written into a log file.
"Length of Window (sec)" - This is the approximate amount of time that is needed to go from the far right side of the graph to the left side of the graph.
"Graph Update (msec)" - This function shows the amount of times that the graph is updated. The value must be large enough to enable the display to move for a minimum of one pixel per update. If the value is too small, the value will be automatically reset to a larger value. This also controls the frequency of writing the data to a log file if logging is enabled.
"Time Update (msec)" - This function controls the frequency of stamping the time on the graph.
"Background Color" - This function allows the background of the graph to be changed. This function is useful for showing contrast.
"Grid Color" - This function changes the color of the grid if the grid is displayed.
"Graph Text Color" - If the "Show Time" is enabled, this function changes the color of the text for the time when the time is written to the graph.
"Enable Logging" - With this function, the logging can be enabled or the logging can be disabled.
"Log Time" - This function determines if the time is recorded. If a simple log is needed, the log is not useful to log the time. However, if more complex analysis of the data is needed, a stamp of time is necessary.
"Log File Name" - This function lists the path of the file and the filename.
Reset Max & Min - This function resets the "Max and Min" values for the current axis to the current value.
Reset All Max & Min - This function resets the "Max and Min" values for all the pens.
Show Max & Min - This function will show a screen that displays the maximum and the difference in a numerical format.
