For fault codes, refer to Section 5.1.16. Self-supervision (IRF) system.
5.1.1.12. Time synchronization
Time synchronization of the relay’s real-time clock can be realized in two different
ways: via serial communication using a communication protocol or via a digital
input.
When time synchronization is realized via serial communication, the time is written
directly to the relay’s real-time clock.
Any digital input can be configured for time synchronization and used for either
minute-pulse or second-pulse synchronization. The synchronization pulse is
automatically selected and depends on the time range within which the pulse occurs.
The time must be set once, either via serial communication or manually via the
HMI.
When the time is set via serial communication and minute-pulse synchronization is
used, only year-month-day-hour-minute is written to the relay’s real-time clock, and
when second-pulse synchronization is used, only year-month-day-hour-minute-
second is written. The relay’s real-time clock will be rounded to the nearest whole
second or minute, depending on whether second- or minute-pulse synchronization is
used. When the time is set via the HMI, the entire time is written to the relay’s real-
time clock.
If the synchronization pulse differs more than ±0.05 seconds for second-pulse or ±2
seconds for minute-pulse synchronization from the relay’s real-time clock, the
synchronization pulse is rejected.
