SER Event Report
Row Triggering
The relay triggers (generates) a row in the SER event report for any change of
state in any one of the elements listed in the SER1, SER2, and SER3 trigger
settings. The factory default settings are:
SER1 = 51P1 51G1 51P1T 51G1T 50P1 50P2
SER2 = IN1 LB1 LB3 LB4 OUT1 OUT2 OUT3
SER3 = CF 79RS 79LO SV5T
