IRIG-B:
Range: Disabled, Enabled
Default: Disabled
This setting enables the IRIG-B signal for time stamp synchronization.
When the IRIG-B setting is enabled, the time received is directly stamped as local date
and time. If there is no signal, one event and alarm is generated. Any other attempted
synchronization commands should be ignored in the main CPU. Since the user has the
capability to enable both SNTP and IRIG-B via the HMI, the system will synchronize to
SNTP, provided SNTP packets are received, when an IRIG-B signal is unavailable.
1.
Set the IRIG-B to "Enabled" if the IRIG-B device is connected to the relay IRIG-B
terminals. The relay will display the message "IRIG-B failure" in the case of either no
IRIG-B signal from the connected IRIG-B device, or when the signal cannot be
decoded.
2.
Set the date and time per the specified date and time format.
3.
Set the start time of the Daylight Saving (DLS) time, by selecting the Month, the Week
of the month, and the Weekday defining the beginning of the Daylight Saving time.
4.
Set the end of the Daylight Saving time, by selecting the Month, the Week of the
month, and the Weekday defining the end of the Daylight Saving time.
The clock has a super-capacitor back-up, so that time, date, and events will be kept for
up to 3 days in cases of loss of relay control power.
