8.3 Configuration of the Device
Recording with the Trend Recorder
The recording of data points (voltage values with a time stamp) that have exceeded/fallen below the parame-
terized tolerance value (fault) and the associated creation of a PQDIF file is determined by 2 trigger criteria:
•
Creation of a PQDIF file after the parameterized Maximum recording interval (for example, 24 h) has
been reached if within this interval no 1024 data points have been generated yet.
•
Creating a PQDIF file without considering the parameterized Maximum recording interval, if the voltage
has exceeded/fallen below the tolerance range 1024 times and therefore 1024 data points have been gen-
erated.

NOTE
A data point is created when the voltage exceeds or falls below the parameterized tolerance value. The data
point represents this voltage value in the PQDIF file.
