is used. See Figure 43.
Figure 43. The Setup>Protection>General Profile 1>Direction 1 Current>TCCs for Test
Sequence-Test 1 screen.
Up to four operations (Test 1 to Test 4) can be specified to follow the Initial Trip event.
The settings entered for Direction 1 can be copied to Direction 2 and then modified as
necessary.
For each Close operation specified in the test sequence, either new TCC curves need
to be entered or the Use Previous TCCs, and retain disk positions command must
be selected with the radio button for that function.
When the Use Previous TCCs command is selected, the TCCs active for the previous
operation will be used. They may be fully or partially reset when the Close operation
occurs. There is no need to enter new TCCs on this screen.
When the Use New TCCs command is selected, the TCCs specified on this screen
are initiated at the time of the Close operation, with all elements fully reset.
The Phase, Ground, Neg. Seq., Sens. Earth, and High Current Lockout con-
figurations found in Test 2, Test 3, and Test 4 are the same as the configurations in
Test 1 and the "Initial Trip" section of the Setup>Protection>General Profile1>
Direction 1 Current screen. All options and ranges are the same as described for the
Initial Trip section. The options and ranges can be copied by selecting the Initial Trip
option or a specific test on the Copy From drop-down menu.
