9.4.4 Operation principle
The function can be enabled and disabled with the Operation setting. The
corresponding parameter values are "On" and "Off".
The reclosing operation can be enabled and disabled with the Reclosing operation
setting. This setting does not disable the function, only the reclosing functionality.
The setting has three parameter values: “On”, “External Ctl” and ”Off”. The setting
value “On” enables the reclosing operation and “Off” disables it. When the setting
value “External Ctl” is selected, the reclosing operation is controlled with the
RECL_ON input .
The operation of the autoreclosing function can be described using a module
diagram. All the modules in the diagram are explained in the next sections.

9.4.4.1 Signal collection and delay logic
When the protection trips, the initiation of auto-reclose shots is in most
applications executed with the INIT_1...6 inputs. The DEL_INIT2...4
inputs are not used. In some countries, starting the protection stage is also used for
the shot initiation. This is the only time when the DEL_INIT inputs are used.
