BE1-25/79TR Functional Description
3-23
A maximum of 100 events can be stored in the relay. The total number of records depends on the number
of events that each record contains. For example, if each record holds 10 events then only the last 10
records are stored.
A 1 indicates that the system parameter (BUS, LINE, SYNC), inputs (52b, DTL, DTR, BLK, HSR, LT1, LT2,
RP1, RP2, PAR, PF, CE), outputs (CLOSE, TRIP, SYNC, LT1 MEMORY, LT2 MEMORY, RP1 MEMORY,
RP2 MEMORY, TRBLE) or timers (LT1, LT2, RP1, RP2, PAR, PF, LO, RST1, RST2, SYNC) are in an off
normal state (active). A 0 indicates that the system parameter, input, output, or timer is in a normal state
(inactive). A - (dash) indicates that the system parameter (BUS or LINE) is in between dead and live. It is
not dead and not live.
Under SYSTEM heading in Figure 3-17, BUS, LINE, and SYNC in the most recent event (top line) have a
0 indicating that the bus and line are live (hot). Therefore, conditions for synchronization are present where
the voltage difference is less than the DIFF V setting, the phase difference is less than the P ANGLE setting,
and the slip frequency is less than the F SLIP setting. Any other conditions will result in an off normal state
and will be indicated with a 1 in the SYSTEM SYNC column.
Under INPUTS in Figure 3-17, an input with a 0 indicates the contact sensing input is open. If the input is
a 1, it indicates that the contact sensing input is closed.
Under OUTPUTS in Figure 3-17, an output with a 0 indicates that the output relay is not energized. If the
output is a 1, it indicates that the output relay is energized. Numbers 1, 2, 3, and 4 are used under the
OUTPUTS, MEM column to distinguish between the four memory outputs. 1 = LT1 memory, 2 = LT2
memory, 3 = RP1 memory, and 4 = RP2 memory. The most recent change in the OUTPUTS, MEM column
will be displayed.
Under TIMERS in Figure 3-16, a timer with a 0 indicates that the timer is not running. If the timer is a 1, it
indicates that the timer is enabled and running.
Keystrokes P (previous record), N (next record), or G XX (go to record number XX) selects the desired
record number.
Keystroke T is used to trigger an event to give a snapshot of the present conditions.
Cursor arrow keystroke up-arrow (
bb
) scrolls the events up one event or down-arrow (
cc
) scrolls the events
down one event. When more than seven events are present in one record, right-arrow (
Y
Y
) scrolls the events
down seven events or left-arrow (
Z
Z
) scrolls the events up seven events.
DATE and TIME are displayed at the top of the screen to indicate when the most recent event in the record
occurred.
The HH:MM:SS.SH under the TIME column indicate the hours, minutes, seconds and second hundredths
when the event occurred.
The screen is automatically updated when a new event occurs. XON (Ctrl-Q) can be used to freeze the
screen and XOFF (Ctrl-S) will restart the screen update. Ctrl-R can be used to refresh the screen with the
latest data.
