Automatic continuation of the reclosing sequence

SMBRREC (79) 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 =
Enabled 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.
