The PXR trip unit is equipped with an integrated real-time clock for displaying
the year, month, day, day of the week, hour, minute and second.
This clock can be set and read using the Power Xpert Protection Manager
(￫ section 6.4, "Power Xpert Protection Manager (PXPM)", page 40) or any
of the communication channels, as well as via the display (in the case of the
PXR25 trip unit). The clock makes it possible to add a time stamp to events
that are recorded in the historical memory.
CAUTION
The real-time clock is not backed by a battery!
It thus needs to be permanently connected to the external
24 V DC power supply.
Should this power supply be interrupted, the real-time clock has
to be set up again.
Eaton's free Power Xpert Protection Manager (PXPM) is a Microsoft®
