Configuration of the Protection Functions for Starting and Blocking the Automatic Reclosing
Function in DIGSI 5
If a protection function or the stage of a protection function is connected with the AREC through the matrix,
this means that the respective pickup and operate indications are forwarded to the AREC.
The links can be conducted separately

For the blocking of the automatic reclosing function
The Automatic reclosing function also has the corresponding binary inputs and binary outputs through which
the external protection devices can be connected to the internal Automatic reclosing function.

Operating Modes for Cyclic Automatic Reclosing Function
For the cyclic automatic reclosing function, there are 4 operating modes, from which one can be selected for
the parameterization (parameter (_:6601:101) 79 operating mode).
The selection of the operating mode is dependent on the tripping behavior of the protection functions and the
circuit breaker.
For applications with 3-pole tripping, all 4 operating modes are available.
•
Operating mode 1: with op., with act. time
•
Operating mode 2: w.pickup, w. action time
•
Operating mode 3: with op., w/o act. time
•
Operating mode 4: w.pickup, w/o act. time
Operating Mode 1: with op., with act. time
The operating mode with op., with act. time allows different automatic reclosing cycles depending
on the tripping type and operate time of the protection function(s). With this operating mode, the automatic
