Example SER Report
This example SER report (Figure 9.3)
corresponds to the event report in Figure 9.1,

Figure 9.3
Example SER Report
The SER event report rows in Figure 9.3 are
explained in the Table 9.7, numbered in
correspondence to the # column. The numbered
comments in Figure 9.1, page 124 also
correspond to the # column numbers in
Figure 9.3. The SER event report in Figure 9.3
contains records of events that occurred before
the beginning of the event report in Figure 9.1,
page 124.

Explanation
13, 12, 11, 10, 9, 8
After a 10-second accelerating time, the motor relay indicates the motor is running (11). later, the
current unbalance alarm element (46UBA, aliased as UNBALNC_I_ALARM) times out, causing the
relay to close output contact OUT1, programmed to indicate protection element alarms (9, 8).
7, 6
The current unbalance trip element (46UBT, aliased as UNBALNC_I_TRIP) times out, causing the
relay to trip. Since now both output contact OUT1 and TRIP are asserted, the relay places a "b" in
the T1 output column of the event report.
5, 4, 3
Declining current due to the opening contactor allows the unbalance detecting overcurrent
elements to drop out and the relay deasserts output contact OOUT1.
2, 1
As the current continues to drop, the relay declares the motor stopped.
