6-26 Reporting and Alarm Functions BE1-CDS220
expression trips an 86 function and the 86 function trips the breaker, the measured clearing time will not
be accurate. To ensure accuracy, the TRIP logic expression must directly trip the monitored breaker. See
the paragraphs on Fault Reporting in this section for more information on the TRIP logic expression and
the Fault Summary reports.
The breaker clearing time can be monitored to give an alarm when the value exceeds a threshold. See
the following paragraphs on Breaker Alarms for more information on this feature.
Breaker Alarms
Three alarm points are included in the programmable alarms for checking breaker monitoring functions.
Each alarm point can be programmed to monitor any of the three breaker monitoring functions
(operations counter, interruption duty, or clearing time). An alarm threshold can be programmed to
monitor each function. Alternately, three different thresholds can be programmed to monitor one of the
monitored functions. Breaker Alarms settings are made using BESTCOMS. Figure 6-12 illustrates the
BESTCOMS screen used to select settings for the Breaker Alarms function. Alternately, settings may be
made using the SA-BKR ASCII command or the HMI using Screen 6.5.2, \SETUP\BKR\ALARM.
