Figure 138: Arc protection with dedicated HSO
The optional autoreclosing function is configured to be initiated by operate signals
from a number of protection stages through the INIT_1...5 inputs. The INIT_6
input in the autoreclosing function block is controlled by a binary input X110: BI2
enabling the use of the external autoreclosing start command. It is possible to create
individual autoreclose sequences for each input.
