The keypad allows the operator or the service technician to communicate with the VIMS main module. The user can select the information that will be shown on the message center display. The operator or the service technician can initiate service procedures. The keypad also allows the operator to enter an identification number and the keypad also allows the operator to acknowledge events.
Pressing any key on the keypad causes key pressed Indicator (2) to FLASH once. This tells the operator or the service technician that the keystroke was accepted.
When a series of related keystrokes (operator ID or service program code) must be entered, each keystroke must be completed in less than five seconds. Periods that last longer than five seconds will cancel any previous keystroke (s). The message center will then return to the previous display mode.
These keys are used to enter numeric information. Some example of numeric information is listed here: operator identification number, service program codes, requested operator responses and selection of individual gauge parameters.
The OK key is used to complete keypad entries and the "OK" key is used to acknowledge events. Examples of the operations of the "OK" key are listed below:
- Responses to system prompts
- Entering an operator identification number
- Stopping the requested gauge parameter
- Return the message center to the background display.
This key is used by the operator to enter a identification number. This number is stored with all event information that may follow, until a new identification number is entered. Printed reports show this number with each event. The "Operator ID" is not required to operate the machine. This is the same "Operator ID" that may be entered via the menu of the loader payload system. Refer to the Systems Operation, "LPS Menu Functions Summary" section of this manual for additional information.
The following message is displayed on the message area after the ID key is first pressed.

| Illustration 2 | g00484268 |
The operator enters an identification number up to seven digits. Then press the OK key. The numbers that are entered are shown on the second line of the message area.

Input Key Functions
OK - Accept the desired operator ID.
ID - Clear the entry line in order to enter an additional operator ID.
GAUGE - Abort the entry mode.
LEFT ARROW - Delete the last character.
Press the "OK" key within five seconds of entering the last keystroke of the operator ID. Otherwise, the operator ID function will be aborted and the message center will return to the previous display mode.
Note: If an event occurs during the operator ID function, the operator ID function is aborted and replaced with event information.
The "GAUGE" key is used to request parameter information. The information will be displayed on the universal gauge and the message area of the message center module. The key may be used in two different ways.
First method: Press the "GAUGE" key once in order to display the first available gauge parameter on the first line of the message area. The second line of the message area displays the values of the gauge parameter. The parameter's relative values are displayed on the universal gauge. An example of the message area is shown here:
| |
| Illustration 4 | g00484272 |
This information is shown for one parameter at a time. The FORWARD and BACKWARD arrow keys are used to scroll through the available parameters.
Second method: Enter the number of the parameter via the keypad. Then press the "GAUGE"key. This method saves time by accessing a specific parameter directly. Otherwise scrolling through the entire parameter list would be necessary.
Requested data remains on the message center module until the OK key is pressed. The background information (time of day and total machine hours) then reappears. During the loading cycle, payload weight is shown for off-highway trucks and large wheel loaders.
Any previously selected gauge function or default data is overridden when an abnormal condition exists. The occurrence of an abnormal condition will cause the event information to be displayed on the message area. After the abnormal condition is corrected or the abnormal condition is acknowledged, the original gauge parameter information will be displayed on the message area.
Use the Parameter Table for a complete list of VIMS parameter names and corresponding numbers. Not all the parameters in the table are used with every machine. If an invalid parameter number (XXX) is entered, the message area shows:

| Illustration 5 | g00484275 |
An example of the message area display for a requested parameter with a failure is shown here:
| |
| Illustration 6 | g00484276 |
Pressing the "F1" key toggles the message center display in order to show service information. This mode replaces the ERR text with a meaningful description of the problem. An example of the message center is shown here:
| |
| Illustration 7 | g00484277 |
Note: For a listing of message center text and FMI codes, refer to the Testing and Adjusting, "Failure Mode Identifier" section of this manual.
FORWARD and BACKWARD Arrow Keys
The arrow keys gives the operator a way to scroll through message area information.
The "F1" key (5) is used by the operator to request additional information about maintenance (system) and data (machine) events. The "F1" key also has special use with LWL payload. Refer to the Systems Operation, "LPS Operating Functions Summary" section of this manual.
- DIAGNOSTIC EVENTS
When a diagnostic type of maintenance event is displayed on the message center, pressing the "F1" key will access additional diagnostic information. The diagnostic information is shown on the second line of the message area.
| |
| Illustration 8 | g00569871 |
The additional diagnostic information is listed here: MID, CID and FMI. An example of the diagnostic information is shown here:
| |
| Illustration 9 | g00484278 |
Pressing the "F1" key again would show the information that was previously shown on the second line.
- DATA EVENTS
When a data event is displayed on the message center, pressing the "F1" key will access additional parameter information.
| |
| Illustration 10 | g00569889 |
The parameter value and units will be displayed on the second line of the message center. An example of the parameter information is shown here:
| |
| Illustration 11 | g00569901 |
Pressing the "F1" key again would show the information that was previously shown on the second line of the message area.
Note: Single Pole Single Throw (SPST) switches are either OPEN or switches are CLOSED, so these switches do not have CID or FMI diagnostic information. Diagnostics for switches will be displayed as the switch status: OK, OPEN, NEUTRAL, UP, etc. An example of the status display is shown here:
| |
| Illustration 12 | g00484280 |
Note: Double Pole Single Throw (DPST) switches can have diagnostic codes.
The "F2" key is not used with applications prior to 9.X software on any VIMS machines. The "F2" key is used with wheel loader payload. Refer to the Systems Operation, "LPS Menu Function Summary" section of this manual.
The "F3" key is not used with applications prior to 9.X software on any VIMS machines. For 9.X or later class of on board software and LWL payload, refer to the Systems Operation, "LPS Menu Function Summary" section of this manual.
