If the data source for the selected quantity is removed, for example,
with Application Configuration in PCM600, the load profile recorder
stops recording it and the previously collected data are cleared.

Length of record

The recording capability is about 7.4 years when one quantity is recorded and the
demand interval is set to 180 minutes. The recording time scales down proportionally
when a shorter demand time is selected or more quantities are recorded. The recording
lengths in days with different settings used are presented in
recording buffer is fully occupied, the oldest data are overwritten by the newest data.
