EVENT RECORDER
4.7.1
Description of Operation
The event recorder in the 28V DC GPU
stores up to 1200 status, alarm and fault
events as they occur, in a First In First Out
(FIFO) scheme. It does not sindicate when
an event turns off. The events are
displayed on several lines in the Apojet LC
Display, with 20 characters per line. The
display starts with the time and date of the
event, followed by the text in the chosen
language, and is completed by the event number. This number is the serial text number in the
text memory and is not the order number of the event memory.
The first character of the Event code has the following meaning:
Exxx
an event has occurred that doesn’t require an acknowledgement
*xxx
an event that must be acknowledged has occurred and has still not been
acknowledged
Rxxx
an event that must be acknowledged has been acknowledged.
(xxx stands for a 3-digit decimal number)
Switching to the event recorder is made by means of the arrow push buttons. The end or the
beginning of the event record is indicated by an arrow displayed in the first line. A “down” arrow
means that the displayed event is the first event in the recorder. An “up” arrow indicates that the
displayed event is the last event and therefore is also the most recent. All events still in the
memory can also be shown on the LC Display using the Up and Down arrows.
