Power Up indication. This

log when the last power

In order to be able to monitor power-ups this information fault code has
been introduced. The time stamp of this information fault code indicates
the time of the last power-up with respect to the “operating hours counter”.
Since this is provided for information only, the status flag of this fault will
always remain cleared.
