10.3.2.18 Automatic continuation of the reclosing sequence
The auto-reclosing function can be programmed to proceed to the following reclosing
shots (if selected) even if the 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.
10.3.2.19 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.
10.3.3 Setting guidelines
10.3.3.1 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.
10.3.3.2 Recommendations for input signals
Please see examples in figure 93 . The figure is also valid for output signals.
