Operation of the VIMS With the Engine Shutdown (Ground Level) Switch

When the VIMS detects a data event that requires VIMS to ask the engine to shutdown, the VIMS will log and display a warning to the operator The engine shutdown data events are listed below:

• High Engine Coolant Temperature

• Low Engine Coolant Level

• Low Engine Oil Pressure

• Low Engine Oil Level

If the ground level shutdown switch is in the ON (NOT RUNNING) position when the VIMS detects the data event, the event will remain active after the condition that caused the data event has been corrected. The engine will not start when the ground level shutdown switch is in the ON (NOT RUNNING) position. The data event will not reset until the ground level shutdown switch has been placed in the OFF ("RUNNING") position and the key start switch is cycled to the OFF position and back to the ON position.

Note: The engine shutdown switch provides the ability to shutdown the engine without being in the cab while the key start switch is in the ON position and the engine is running. When the engine shutdown switch is placed in the ON (NOT RUNNING) position, the fuel injection to the engine is disabled after 1 second. Once the engine shutdown switch has been activated the engine will not start again until, the engine shutdown switch is placed in the OFF ("RUNNING") position and the key start switch is cycled to the OFF position and back to the ON position.

An Example of The VIMS Operation

Initial Conditions

• The engine shutdown switch is in the ON (NOT RUNNING) position.

• The key start switch is turned to the OFF position.

• The engine is not running.

The Machine Condition That Caused the data event

The engine coolant level is below the specified level.

The Response of the VIMS

The operator turns the key start switch to the "ON" position. The VIMS correctly logs a data event in the event list and displays the following warning on the message center:

The operator presses the "F1" key for additional information.

The engine coolant level was then filled to the specified limit. The operator then check the status the engine coolant level. The message center displays the following message:

The VIMS indicates the coolant level is OK. Then, the operator cycles the key start switch to the OFF position and back to the ON position. The VIMS ran through the power up self test (reboot), but the engine did not start. The message center incorrectly displays the following message:

The message center displayed the following message when the "F1" key was pressed:

The operator checks the position of the engine shutdown switch. The engine shutdown switch is moved to the OFF (RUNNING) position. The message center still displays the following message:

The operator cycles the key start switch to the OFF position and back to the ON position again. The VIMS runs through the power up self test and no warning is displayed. The operator was then able to start the engine.

This behavior applies to only the data events. The diagnostic events will not display after the condition has been corrected.
