19.6 Summary of Datalogger File Functions

Following is a summary of the function of the Datalogger files saved to the compact flash card. (The name of
the datalogger file changes slightly when saved to the compact flash card).
Fault Log
The fault log records all faults that occur. Around 50 000 records are saved per file after which the file rolls
over to faults.0.
Event Log
The event log records all events that occur within defined dead bands (a minimum amount by which the
value must change before it is logged). Around 50 000 records are saved per file after which the file rolls
over to events.log.0.
EFault Log
Events are logged surrounding a fault. Around 50 000 records are saved per file after which the file rolls
over to faults.log.0. The events logged are timed based (not dead band based as per events.log) i.e. after a
fixed amount of time, the status of the event is logged. A buffer is maintained so that these events are
captured before and after a fault occurs.
