MESSAGE
The relay has an internal real time clock that performs time and date stamping for various
relay features such as event, maximum demand, and last trip data recording. Time
stamping on multiple relays can be synchronized to ±5 ms with the use of an IRIG-B input.
The clock has a supercap back-up so that the time and date are maintained on the loss of
relay control power. The time and date are preset at the factory, but should be changed to
correspond to the appropriate time zone.
Enter the current date and time here. The new date and time take effect the instant the
key is pressed.
ENTER
The setpoint enabled the IRIG-B time synchronization and selects the
IRIG-B SIGNAL TYPE
type of IRIG-B signal to use. The IRIG-B signal contains all necessary time and date
stamping data except for the year. The year must be entered with the date. If IRIG-B is
enabled and functioning properly, then setting the time and date (except for the year) as
described in the previous message will have no effect. If IRIG-B is enabled but the signal
cannot be decoded, the
