Automatic continuation of the reclosing sequence

SMBRREC function can be programmed to proceed to the following reclosing shots
(if multiple shots are selected) even if start signals are not received from the protection
functions, but the breaker is still not closed. This is done by setting parameter
AutoCont = On and tAutoContWait to the required delay for the function to proceed
without a new start.

Thermal overload protection holding the auto-reclosing function back

If the input THOLHOLD (thermal overload protection holding reclosing back) is
activated, it will keep the reclosing function on a hold until it is reset. There may thus
be a considerable delay between start of Auto-Reclosing and reclosing command to
the circuit-breaker. An external logic limiting the time and sending an inhibit to the
INHIBIT input can be used. The input can also be used to set the Auto-Reclosing on
hold for a longer or shorter period.

Setting guidelines

Configuration

Use the PCM600 configuration tool to configure signals.
Autorecloser function parameters are set via the local HMI or Parameter Setting Tool
(PST). Parameter Setting Tool is a part of PCM600.
