The function can be enabled and disabled with the Operation setting. The corresponding parameter values are "On" and "Off". Setting Operation to "Off" resets non-volatile counters.
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. AR_ON is activated when reclosing operation is enabled.
The operation of DARREC can be described using a module diagram. All the modules in the diagram are explained in the next sections.
