In case of a missing or discharged battery, the device starts without active external time synchronization
with the device time 2011-01-01 00:00:00 (UTC).
For the device, DIGSI 5 provides a compact overview of the status of the time synchronization of your
SIPROTEC 5 device in online mode. All displays are updated continuously. You can access the overview in the
project-tree window via Online access.

Description
This indication signals a high difference between the
internally managed time and the time of the clock
module that is not permissible. The pickup of the indi-
cation can point to a defect in the clock module or to
an unacceptable high drift of the system quartz
crystal. The time maintained internally is marked as
invalid.
This indication signals whether daylight saving time
has been enabled.
This indication signals that the device time has been
set manually via the on-site operation panel or via
DIGSI 5.
These 2 indications signal whether the active time
sources are recognized as valid and active from the
device point of view. When the indications pick up, it
can also be an indication that an incorrect configura-
tion of the port or channel numbers was done at the
on-site operation panel.
This indication signals after the parameterized time
Fault indication after that synchronization
using an external time source has failed.
This indication signals that a Leap second has
occurred during time synchronization using an
external GPS receiver (protocol variant IRIG-B
005(004) with extension according to IEEE
C37.118-2005).
This indication signals that the device is synchronized
with an accuracy better than 1 μs The indication is
only of significance when the PMU function is used.
