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.

Two detected pulses within acceptable time range are required before the relay

activates pulse synchronization. Respectively, if the synchronization pulses

disappear, the relay takes time that corresponds to the time range of four pulses

before de-activating pulse synchronization. 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-minutesecond 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 realtime clock
