Setting guidelines

Remember always that there are two possible ways to place the IED in the
TestMode= On" state. If, the IED is set to normal operation (TestMode = Off), but
the functions are still shown being in the test mode, the input signal IED_TEST on
the TESTMODE function block is activated in the configuration.
Forcing of binary input and output signals is only possible when the IED is in IED
test mode.

Time synchronization TIMESYNCHGEN

Setting guidelines
All the parameters related to time are divided into two categories: System time and

Synchronization.

System time

The system time can be set manually via the local HMI under Main menu/
Configuration/Time/System time. The time is set with years, month, day, hour,
minute, second and millisecond. In addition, there are also settings for Day-Light-
Saving and adjustment of Time-Zones.
Synchronization
The setting parameters for the real-time clock with external time synchronization
are set via local HMI or PCM600. The path for Time Synchronization parameters
on local HMI is Main menu/Configuration/Time/Synchronization. The
parameters are categorized as Time Synchronization (TIMESYNCHGEN) and
IRIG-B settings (IRIG-B:1) in case that IRIG-B is used as the external time
synchronization source.
Time Synchronization
The time synchronization (TIMESYNCHGEN) parameters are divided in two
categories, "general" and "IEC61850-9-2" parameters.
The general parameters are as follows:
• FineSynchSource
• SynchMaster
FineSynchSource: This parameter is used to select the time synchronization source.
The options are "Off", "GPS", "IRIG-B", or "GPS+IRIG-B". In case that both GPS
and IRIG-B are used (GPS+IRIG-B) for redundant time synchronization, the PMU
will automatically select the most accurate time synchronization source.
