MONITORING
4–274
OPEN STATUS
Range: Off, Any FlexLogic operand
Default: Off
The setting selects the signal to show the open status of the breaker. If the contact input
is not configured, the detection of open status is delayed by an extra debouncing time.
CLOSE STATUS
Range: Off, Any FlexLogic operand
Default: Off
The setting selects the signal to show the close status of the breaker. If the contact input
is not configured, the detection of close status is delayed by an extra debouncing time.
SPRING CHARGE STATUS
Range: Off, Any FlexLogic operand
Default: Off
The setting selects the signal to show the status of Spring Charge. Normally, the contact
input connected to the auxiliary contact of the limit switch can be used.
TRIP TIME PICKUP
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.050 s
The setting sets the Pickup level of the Trip time. The Trip time interval is initiated by the
TRIP TRIGGER signal and stopped by the OPEN STATUS signal.
CLOSE TIME PICKUP
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.050 s
The setting sets the Pickup level of the Close time. The Close time interval is initiated by
the CLOSE TRIGGER signal and stopped by the CLOSE STATUS signal.
INCOMPLETE TRP/CLS TIME
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.100 s
The setting declares a breaker operation failure condition if the breaker does not
respond within this time delay. The setting should be greater than the Trip time PKP
value and Close time PKP value.
ARC TIME PICKUP
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.100 s
The setting sets the Pickup level of the Arc time. The Arc time is initiated by the OPEN
STATUS signal and stopped when the current samples in one cycle are less than 0.02 CT.
Then the Arc time is equal to the calculated time interval minus one cycle.
INCOMPLETE ARC TIME
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.300 s
The setting declares an Arc time failure condition if there are currents flowing through
the breaker after this time delay. This setting should be greater than the Arc time PKP
value.
SPRING CHARGE TIME PICKUP
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 15.000 s
This setting sets the Pickup level of the Spring Charge time. The Spring Charge time is
measured from the pulse duration of the SPRING CHARGE STATUS.
