priority over P6B). If the unit is optioned for PTP operation, it can also sync to time from a distant
PTP Master clock.
If all sync is lost, the TCG 01-
the alarm condition is signaled. When sync is restored, the alarm condition is retained for 5 seconds
before being cancelled.
The alarm outputs are Type A (normally-open) dry contact types (implemented using solid state
relays).
Normally-Open
convention used in the TCG 01-G is to have the alarm relays energized during normal operation, and
de-energized in the alarm state. In the case of all power to the clock being lost, all of the alarm relays
