Number of Tests
Specify the number of tests to be performed (up to four).
Initial Trip
3-Phase mode is the only option available.
Test-1 Delay, Test-2 Delay, Test-3 Delay, Test-4 Delay
Specify the open time (in seconds) between each test. (Minimum: 0.18 for Time-1, 1.80
for Time-2, 10.00 for Time-3, 30.00 for Time-4; Maximum: 655.00; Increment: 0.01)
SEF Sequence
Close-testing is the only option available.
SEF Sequence Reset Time
Specify the test sequence reset time (in seconds). (Range: 0-600; Step: 1) The same
Sequence Reset Time period is used for all test sequences. When 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 resets and any TCC curve that has changed will reset to its
Initial Trip setting. When the Intelligent Fuse Saving (IFS) mode 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 settings for at least two cycles, the IFS elements are turned off for the
duration of the 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 on the
base curve, it enters a test sequence as usual. The IntelliRupter fault interrupter stays
in its Initial Trip state unless it trips on the base curve. This is not the Sequence
Coordination feature exclusive to the IFS mode.
When the O/C and IFS Sequence Reset Time period expires and no elements have
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.
