If there is an Event (Fault) occurring in the system, the Status LED on the front panel will
flash RED as long as the Event (Fault) is present. In addition, the menu will jump to the
current Event (Fault) on the display and blink the Event (Fault) continuously, if the Jump to
Fault screen is set to Yes. When the Event (Fault) is corrected, the tray will turn the Status
LED to AMBER to indicate that there was a Fault and the menu will still display the Fault but it
will not flash. This gives the user the knowledge that there was an Event (Fault) and what
type of Event (Fault) occurred. Before clearing the fault, check if there were other Events
(Faults) by stepping through the menus. To reset the indication of previous Events (Faults)
the user must push the Enter button with the Event (Fault) Reset Screen displayed. This will
reset all previous Events (Faults).
