of relays where the relays do not include this function, the
PERMIT1PH output) is used to prepare the other sub-system for three-phase tripping. This signal
will, for evolving fault situations, be activated a short time after the first trip has reset and will
thus ensure that new starts (trips) will be three phase.
14.2.2.21 Automatic continuation of the auto reclosing sequence
The auto recloser can be programmed to proceed to the next auto reclosing shots (if multiple
shots are selected) even if start signals are not received from protection functions, but the circuit
breaker is still not closed. This is done by setting
required delay for the function to proceed without a new start.

THOLHOLD input (thermal overload protection holding auto reclosing back) is activated, it
If the
will keep the auto recloser on a hold until it is reset. There may thus be a considerable delay
between start of the auto recloser and the breaker closing command to the circuit breaker. An
external logic limiting the time and sending an inhibit to the
can also be used to set the auto recloser on hold for a longer or shorter period.
14.2.3 Setting guidelines
14.2.3.1 Configuration
Use the PCM600 configuration tool to configure signals.
Auto recloser function parameters are set via the local HMI or Parameter Setting Tool (PST).
Parameter Setting Tool is a part of PCM600.

These binary inputs should pick-up information from the circuit breaker. At three operating gears
in the circuit breaker (single pole operated circuit breakers) the connection should be "All poles
closed" (series connection of the NO contacts) or "At least one pole open" (parallel connection of
NC contacts). The

of type "circuit breaker not charged" or "not ready", an inverter can be inserted in front of the
