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.
Autorecloser for 1/3-phase operation function parameters are set via the local HMI or
Parameter Setting Tool (PST). Parameter Setting Tool is a part of PCM600.
Recommendations for input signals
Please see examples in figure 143. The figure is also valid for output signals.
