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 drawer 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).
