Figure 12.5: Example Sequential Events Recorder (SER) Event Report
The SER event report rows in Figure 12.5 are explained in the following text, numbered in
correspondence to the # column. The circled, numbered comments in Figure 12.2 also correspond
to the # column numbers in Figure 12.5. The SER event report in Figure 12.5 contains records of
events that occurred before and after the standard event report in Figure 12.2.
SER
Row No. Explanation
19 Relay newly powered up.
18 Input IN2 is asserted to enable reclosing.
Related setting: 79DTL = !IN2 + ... [=NOT(IN2) + ...]
17, 16 Local bit LB4 is operated from the front panel to assert close output contact OUT2
to close the circuit breaker (see Figure 6.1).
Related settings: CL = LB4 (LB4 operates as a manual close)
OUT2 = CLOSE
15 Local bit LB4 deasserts automatically the next 1/4 cycle – close signal is latched in
by close logic.
