It is possible to determine the behavior of alarms that are in alarm list when Fault Reset button is
pressed. Select behavior with ComProtSetting:ResetActAlarms.

only
inactive
alarms. Active alarms remain in the alarmlist unchanged and must be
reset again when they become inactive.
ENABLED
Pressing of the fault reset button (at any terminal or external button)
resets
all
alarms that are currently present in the alarm list. Inactive alarms
disappear from the alarm list immediately, active alarms are changed to "confirmed"
state and disappear when the alarm condition disappear or the alarm starts to be
blocked.

Bus Measurement Error detection
InteliMains is able to detect Bus Measurement Error. It is evaluated based on gen-sets and mains
incommers.
GEN-SETS: If any gen-set from the logical group that is connected to the InteliMains has closed
breaker and InteliMains is not measuring correct values on Bus it automatically detects bus
measurement error.
MAINS: If any Mains incomer is connected to the bus (provided that all corresponding Bus Tie
Breakers are closed as well) and InteliMains is not measuring correct values on Bus it automatically
detects bus measurement error.
