Informational and Settings Screens
Open Interval following Initial Trip, Test 1, or Test 2. Specify interrupter open
time (in seconds) before it recloses after the initial Trip operation, after Test 1, or after
Test 2, as applicable (minimum value: 0.5; maximum value: 5 [or 30 for extended open
interval-capable reclosers]).
O/C Sequence Time. Specify the reset time for the test sequence, in seconds (minimum
value: 0.5; maximum value: 1000). If a TripSaver II recloser remains closed upon comple-
tion of an action in the test sequence—and the overcurrent element has not picked up
and started timing again within this setting—the test sequence counter will reset and
the TCC curve will reset to its setting dened in the Trip operation.
Note: An active O/C Sequence Time timer will not expire after a TripSaver II recloser
loses power. It will continue counting down until the defined duration has been reached.
Default TCC Curve Settings
The software launches with a set of default TCC curve settings that match those pro-
grammed into every standard TripSaver II recloser before it leaves the factory. This is
the starting point of the conguration process. The S&C default TCC curve settings are
