SER Triggering
The control triggers (generates) an entry in the SER report for a change of state of any one of the
elements listed in the SER1, SER2, and SER3 trigger settings. The factory default settings are:
SER1 = TRIP 51P1T 51P2T 51G1T 51G2T 51N1T 51N2T 67P2T 67G2T 67N2T
67N3T 81D1T PB9 67P1 67G1 67N1
SER2 = CLOSE 52A CF 79CY 79LO 79RS SH0 SH1 SH2 SH3 SH4 PB8 59A1
SER3 = TOSLP BCBOK DTFAIL
The elements are Relay Word bits referenced in Table 9.3. The control monitors each element in
the SER lists every 1/4 cycle. If an element changes state, the control time-tags the changes in
the SER. For example, setting SER1 contains:
•
Time-overcurrent element trips (51P1T, 51P2T, 51G1T, 51G2T, 51N1T, and 51N2T)
•
Definite-time overcurrent element trips (67P2T, 67G2T, 67N2T, 67N3T)
•
Definite-time frequency element (81D1T)
•
