Synchronizing Impulses#

In a time distribution system, where the digital clocks are controlled by polarized impulses, set the SYNC menu item o2 to according type of the impulse line (one minute, half minute, second pulses).

1. Configure the DIP switch to LINES positon (default setting).

   

2. Set following items:

   • In the SYNC menu, set item o1 to value A (see Timezone of Synchronization Source chapter)

   • In the SYNC menu, set item o2 to value A (see Type of Synchronization chapter)

   • In the dISP menu, set item d2 to your desired time zone (see Timezone of Time and Date chapter)

3. The clock time‑base is synchronized by incoming pulses in normal operation of the slave line.

4. Set current date and time in the tIME menu according to MASTER clock with accuracy of ±30 seconds (or ±15 seconds, or ±0.5 second respectively).

5. The colon flashes in 2 second interval.

6. After 2–3 minutes are the clocks synchronized with the MASTER clock. The colon is permanently lit during the display of time.

7. 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.
