Interfaces

The digital display will communicate over the J1939 protocol. The display is programmed according to J1939 as defined by SAE and Caterpillar Inc. Button controls are defined below.

Home Screen

Once the Dosing Cabinet Display is started up, the home screen will appear. The default screen format is the 4Up display, however the format is changed, the display will resume the last know format on the next power-up.

The user will be able to scroll through various aftertreatment parameters using the RIGHT and LEFT arrow buttons (buttons 3 and 4) and will also allow the user to access the main menu by pressing the LIST button (button 2).

Note: Pressing the LIST button (button 2) at any time will work as a “back” feature and bring you back to the previous screen.

Suspect Parameter Number (SPN)

The Dosing Cabinet will detect the J1939 parameters being broadcasted by the ECU and populate the display parameters according to the detected parameters. The Dosing Cabinet will scan the J1939 network for 2 minutes after start-up. During the first two minutes only two 4 UP screens will be accessible to the user. After the scanning period has ended, the number of available screens will be altered based on the number of parameters detected by the active SPN array feature. Display screens will be populated in the order that parameters are detected with the following exception:

• For both 1UP and the 4UP screens, the first eight parameters should consist of the ones seen in the table below. If any of these parameters are not detected, the spot where this parameter was located should be replaced with the next available detected parameter from the below table.

• Table 1 lists all available parameters on the data link. Only the ones marked with an X are available on the 1Up and 4Up display features.

The 1UP and 4UP will accommodate the varying number of parameters by changing the number of screens displayed. The 1UP will allow the operator to cycle through all detected parameters one at a time in a loop. The 4UP will create a varying number of screens at start-up when parameters are detected. The number of screens created will be the minimum required to show all detected parameters (excluding Dosing Information parameters). If the number of detected parameters is not evenly divisible by four, then the last 4UP display screen created will have unused spaces that are left blank. Life and Trip parameters are not affected by the active SPN array. These parameters will be programmed into the Dosing Cabinet Display. A complete list of SPNs that will be supported by the Dosing Cabinet Display.

SPN/FMI Diagnostic Arrays

The SPN and FMI list will be separated for storage in the Dosing Cabinet Display. When an error is received, the display will collect the SPN and FMI separately and combine the text strings to be displayed to the operator. This action will give the display more memory efficient way of storing errors and their respective text strings. All required SPN/FMI can be found below.

Language

This display is only available in English.

Software Version

Software version is only used by a trained Caterpillar technician to determine that the latest available software has been up loaded. This feature is not needed for normal system operation.

Aftertreatment Hour Meter

The aftertreatment system is equipped with an hour meter unique from the engine hour meter. The hour meter tracks the number of hours of operation of the aftertreatment system once the engine speed exceeds 200 rpm. It is expected that the aftertreatment service meter will not match the engine service meter primarily due to the time spent at low idle which accumulates on the engine hour meter but not on the aftertreatment hour meter.
