Reset logic

For many monitoring functions, ACBMSCBR can reset the internal status by clearing the old values
and re-starting the respective algorithm.
If the operating environments change, for example the circuit breaker has undergone maintenance or
the IED is used to switch a different breaker, it is recommended to reset the internal values of
accumulated parameters to avoid erroneous calculations. The clear or resetting options can be
accessed through LHMI or WHMI by navigating to Clear/Clear CB cond. indicators.
The function provides the following reset features:
• Reset adaptive closing time correction
• Reset ablation
• Reset operation count
• Reset re-strike/re-ignition count
• Reset re-strike/re-ignition correction
• Reset unstable detection
Reset adaptive closing time correction
This function allows the user to flush the older correction values and restart the close adaptive
corrections freshly. Upon receiving the positive edge of binary input RESADCOMP (RESADCOMP
