Appendix L-3
Operations Count Monitoring
Definition – The breaker operations count since last reset/preset.
Desired Behavior – Alarm if the counter is greater than the Count Limit Pick-
up. Timer T1 pickup delay is used to provide a de-bounce time for the circuit
breaker 52a contact. Timer T2 drop out delay is set to one second, for creating
the desired Alarm pulse width.
The message parameter setting is used to define the event log message.
The Alarm LED Enabled setting is used to tell the F-PRO to turn on the front
panel led. In this example T2 drop out timer is set for creating the desired
Alarm pulse width. An alternative setting could be applied with a latch gate to
keep the alarm condition present until Virtual Input 1 is pulsed high.
