A specialized user defined detection logic for each channel, monitors permanently the criteria defining a fault and the status triggering the record of an incident. Qualitrol’s extreme digital fault recorders contains a whole library of triggers, each one having its own detection algorithm. The user can choose whichever combination of triggers best suits his needs. For each of these, the triggering levels are remotely programmable.
- All input signals are sampled synchronously at a programmable frequency
- Each analog input has its own anti-aliasing filter to eliminate undesirable frequencies
- As soon as triggering occurs, the recording cycle contained in the pre-fault memory is stored with post-fault recording
