The auto-reclose function consists of six individual auto-reclose initiation lines INIT_1...INIT 6 and three delayed initiation lines:
- DEL_INIT_2
- DEL_INIT_3
- DEL_INIT_4
DEL_INIT_2 and INIT_2 are connected together with an OR-gate, as are inputs 3 and 4. Inputs 1, 5 and 6 do not have any delayed input. From the auto-reclosing point of view, it does not matter whether INIT_x or DEL_INIT_x line is used for shot initiation or blocking.
The auto-reclose function can also open the circuit breaker from any of the initiation lines. It is selected with the Tripping line setting. As a default, all initiation lines activate the OPEN_CB output.
Each delayed initiation line has four different time settings:
| Setting name | Description and purpose |
|---|---|
| Str x delay shot 1 | Time delay for the DEL_INIT_x line, where x is the number of the line 2, 3 or 4. Used for shot 1. |
| Str x delay shot 2 | Time delay for the DEL_INIT_x line, used for shot 2. |
| Str x delay shot 3 | Time delay for the DEL_INIT_x line, used for shot 3. |
| Str x delay shot 4 | Time delay for the DEL_INIT_x line, used for shots 4 and 5. Optionally, can also be used with SOTF. |
