NormClosed and connect a CB auxiliary contact of type NC (normally closed) to
inputs CBPOS and START. When the signal changes from CB closed to CB open an
auto-reclosing start pulse of limited length is generated and latched in the function,
subject to the usual checks. Then the reclosing sequence continues as usual. One needs
to connect signals from manual tripping and other functions, which shall prevent
reclosing, to the input INHIBIT.
