TRANSIENT RECORDER CHAPTER 10: DIGITAL FAULT RECORDER
Front panel indications
The digital fault reporter summary screen provides an indication that the transient
recorder is ready to capture data and has memory available. In protected mode, the
Ready
to Capture indication is green when all of the following conditions hold.
• The transient recorder is enabled.
• The block trigger input is not asserted.
• Memory is available.
• A record capture is not currently in progress.
Otherwise the indication is red. In automatic overwrite mode, the Ready to Capture
indication is green when all of the following conditions hold.
•
The transient recorder is enabled.
• The block trigger input is not asserted.
• A record capture is not currently in progress.
The Memory Available indication is green when less than 80% of the memory has been
filled. It is yellow when the amount of memory filled is between 80% and 99%, and it is red
if 100% of the memory is filled.
Figure 442: Digital fault reporter summary screen
The transient recorder screen shows the individual records stored on the device. This
screen also has an indication of any active triggers (red indication) for the transient
recorders. If a continuous trigger is permanently active, it will not fill the memory of the
recorder. After the first record is generated it is effectively disabled by the trigger logic;
however, its status will be displayed on this screen. The user can also force triggering of the
recorder from this screen.
