Figure 23: Arc protection
The optional autoreclosing function is configured to be initiated by trip signals from a
number of protection stages through the INIT_1...5 inputs. It is possible to create
individual autorecloseing sequences for each input.
The autoreclosing function can be inhibited with the INHIBIT_RECL input. By default,
few selected protection function operations are connected to this input. A control
command to the circuit breaker, either local or remote, also blocks the autoreclosing
function via the CBXCBR1_52-1_SELECTED signal.
The circuit breaker availability for the autoreclosing sequence is expressed with the
CB_READY input in DARREC1_79. This signal is not connected in the configuration.
The open command from the autorecloser is connected directly to binary output
X100:PO3, whereas the close command is connected directly to binary output X100:PO1.
Set the parameters for DARREC1_79 properly.
