S&C IntelliRupter PulseCloser Manual page 75

Trip
Specify from the drop-down list 1-Phase or 3-Phase mode.
O/C Sequence (R2 control)
Specify the action to be performed during each Phase Overcurrent test. Select from the
drop-down list: the Pulse option for a test using PulseClosing Technology or the Close
option.
O/C Sequence (R3 control)
For the Overcurrent Sequence setpoint specify the action to be performed during each
Phase Overcurrent test. Select from the drop-down list: the Pulse Close option for a test
using PulseClosing Technology or the Point-On-Wave (POW) Close option.
IFS Sequence (R2 control)
Specify the action to be performed during each Intelligent Fuse Saving test. Select from
the drop-down list: the Pulse option for a test using PulseClosing Technology or the
Close option.
IFS Sequence (R3 control)
Specify the action to be performed during each Intelligent Fuse Saving test. Select from
the drop-down list: the Pulse Close option for a test using PulseClosing Technology or
the Point-On-Wave (POW) Close option.
O/C and IFS Sequence Reset Time
Specify the test Sequence Reset Time setting (in seconds). (Range: 0-600;
Step: 1) The same Sequence Reset Time setting is used for all test sequences. If the
IntelliRupter fault interrupter remains in the Closed state at the completion of an action
in the test sequence and no overcurrent element has picked up and started timing within
this setting, the Test Counter indicator resets and any TCC that has changed will reset
to its initial trip setting. When the Intelligent Fuse Saving (IFS) setting is configured
and the IFS element (phase and/or ground) picks up and starts timing for a minimum of
two cycles and then the current goes below both the Phase Minimum Trip and Ground
Minimum Trip thresholds for at least two cycles, the IFS elements are turned off for
the duration of the configured O/C and IFS Sequence Reset Time period.
When another fault occurs within the O/C and IFS Sequence Reset Time period,
only the base curve will be active. When the IntelliRupter fault interrupter trips using
the base curve, it enters the test sequence as usual. The IntelliRupter fault interrupter
stays in the Initial Trip state unless it trips on the base curve. This is not the Sequence
Coordination feature that is exclusive to the IFS mode.
When the O/C and IFS Sequence Reset Time period expires and no elements are
picked up, the IFS mode is reinstated and the IntelliRupter fault interrupter is reset to
the Initial Trip state. The IFS mode is only active in the Initial Trip state, and this
feature only applies when the IFS mode is active.
