CLOCK

[ENTER] for more
The relay has an internal real time clock that is used to perform 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 ±1 ms with
the use of an IRIG-B input. The clock has a battery 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
The
IRIG-B SIGNAL TYPE
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
warning is generated.

EVENT RECORDER

[ENTER] for more
The relay captures a wide variety of events and stores the last 128 in non-volatile memory. See Section 6.5.1: Event
Records on page 6–16 for details. A single power system disturbance could conceivably fill half of the event recorder due to
the various events that can be captured. Also, some events may happen on a regular basis as part of a control scheme
(e.g. Power Factor events in a capacitor bank switching scheme). For this reason, certain event types can be 'filtered' from
the event recorder to save room for other events. The following setpoints describe the events that can be filtered.
