FYI – Synchronous Wired Correction Protocol for National Time EX-HH and EX-LV Series Run relay is normally operated to pass source power through to the clock run motors. Each hour from HH:00:00 to HH:00:28 correction relay SK2 is operated which passes source power through to the clock correction coils for 28 seconds and causes hourly correction. Correction relay is again operated every 12 hours from 6:00:00 to 6:27:27 to pass source power through to the clock correction coils, causing a 12-hour correction.
