4.4.1 Synchronization and time setting – o3 mode 1 and 3
•
Clocks are set according to the slave line time on the Master clock.
•
Stop the slave line on Master clock.
•
Set all Slave clocks on the same time. Set the current date on the digital clock. The clock stand still
and the colon flashes in 2 second interval.
•
Set the time of the slave line to the same time as on Slave clocks.
•
Run the slave line on Master clock.
•
After receiving each impulse, the displayed time is increased by one minute (or by 30 seconds
or 1 second respectively).
•
After expiration of run‑out time the Slave clocks are synchronized by the time information generated
by the Master clock, the colon flashes constantly.
•
In case of the line fault, the clock displays the right time information based on its own quartz time
base. When the normal operation of the line resumes, the Slave clock adjusts itself to the time
equal to the Master clock.
4.4.2 Synchronization only – o3 mode 2 and 4
•
The clock time‑base is synchronized by incoming pulses in normal operation of the slave
line.
•
Set current date and time on the Slave clock according the Master clock time with accuracy
of ±30 seconds (or ±15 seconds, or ±0.5 second respectively).
•
The colon flashes in 2 second interval.
•
After 2–3 minutes are the clocks synchronized with the Master clock. The colon is permanently lit
during the display of time.
•
In case of the line fault, the clock displays the right time information based on its own quartz time
base. When the normal operation of the line resumes, the clock synchronizes with the incoming
pulses.
