8.2.3 REQUEST FAULT INFORMATION
This category is used to display fault information. When this category is selected, a summary of the fault information for the
stored faults is displayed to facilitate the user choose a fault for viewing more information about it. An example is shown
below:
where:
XXX: Fault type
YYY: Trip type
MM/DD HH:MM: Date and time of occurrence
The number in the top right-hand corner indicates the selected fault. When the category is entered, the number is #1 and
the cursor is on the first fault. The arrow keys may be used to scroll through the list of accumulated faults. The number on
the top line will change to match the currently selected fault. The user can also enter the fault number to view. If the number
is valid when the user presses [ENT] key, the cursor will be placed on the selected fault description. An error message is
displayed if the user enters an invalid number.
The user has to press [ENT] key to view all the fault information. An example is shown below:
