10.3.6.10 Automatic continuation of the reclosing sequence
The auto-reclosing function can be programmed to proceed to the following reclosing shots (if
selected) even if the initiate signals are not received from the protection functions, but the
breaker is still not closed. This is done by setting parameter
tAutoContWait to the required delay for the function to proceed without a new initiate.
