Section 12
Monitoring
binary input status changes from 0 to 1), the function resets the adaptivecorrection to zero. The result
can also be observed on the output ADAPTCLLX which gives a value of zero.
The adaptive closing time correction can be cleared through LHMI or WHMI by navigating to Main
menu /Clear / Clear CB cond. indicators /Clear adaptive comp .
Reset ablation
The function allows the user to clear the old accumulated values of monitored ablation and restart the
ablation calculation. The function resets the accumulated ablation, and assigns the value of
InitialCumAbl, when function receives the positive edge of binary input RESETABL (RESETABL
binary input status changes from 0 to 1). The result can also be observed on the output ABLSUMLX
which gives the value of InitialCumAbl.
The resetting of ablation values can also be accessed through LHMI or WHMI by navigating to Main
menu /Clear / Clear CB cond. indicators /Clear CB wear .
Reset operation count
The function allows the user to clear the old operation counts and restart the operation count freshly.
The function resets the open-close operation count (OPRCNTRST) and assigns the value of
InitialOpCnt, accumulated in-sync operation count for open (INOPCNOLX) and accumulated in-sync
operation count for close (INOPCNCLX) setting the value to zero, when function receives the positive
edge of binary input RESETOPCNT (RESETOPCNT binary input status changes from 0 to 1).
The operation count can also be cleared through LHMI or WHMI by navigating to Main menu /Clear/
Clear CB cond. indicators /Clear operation count.
Reset re-strike/re-ignition count
The function allows the user to clear the old detected operation counts of re-strike/re-ignition and
restart the count. The function resets the accumulated operation counts of re-strike or re-ignition
(RTKCTLX) to zero, when RESRCNT is activated.
The re-strike or re-ignition count can also be cleared through LHMI or WHMI by navigating to Main
menu/Clear/ Clear CB cond. indicators/Clear restrike count .
Reset re-strike/re-ignition correction
This function allows the user to remove the older correction values and restart the adaptive
correction for CB open operations. The function resets the re-strike or re-ignition correction to zero
when function receives the positive edge of binary input RESRESTR (RESRESTR binary input status
changes from 0 to 1).
The result can also be observed on the output ADAPTOPLX which gives a value of zero.
The re-strike/re-ignition correction can also be cleared through LHMI or WHMI by navigating to Main
menu /Clear / Clear CB cond. indicators /Clear restrike correction .
Reset unstable detection
The function allows the user to clear the unstable detection of the breaker. The function resets the
internal counter of inconsistent switching operations of the breaker when RESETUNST is activated.
After resetting the CB instability, the output UNSTOPOLX is deactivated.
The unstable detection can also be cleared through LHMI or WHMI by navigating to Main menu /
Clear/ Clear CB cond. indicators /Clear unstable mode.

Temperature handling logic

ACBMSCBR doesn't directly measure the temperature or evaluate any information related to
temperature. It only includes an internal connection between the dedicated temperature input and
output: The analog value of temperature received on the TMPIN input is directly forwarded to the
TMPOUT output.
