Signal Description Routing Options
Close command
This signal executes all closing operations.
The Output time parameter affects the signal.
The signal is pending for the duration of this period, with
the following exception: The signal is canceled before
expiration of the period if the auxiliary contacts report
that the circuit breaker is closed before expiration of the
period.
Closing operations are always 3-pole operations.
Normal routing
Command active
This signal is active as long as one of the binary outputs
assigned to the signals Trip/open cmd. 3-pole and
Close command is active because a switching command
is being executed by the control.
Normal routing
Acquisition of Circuit-Breaker Auxiliary Contacts and Further Information
To determine the circuit-breaker switch position, the Circuit-breaker function block provides position signals
(see next figure).
These signals are of the Double-point indication (DPC) type. A double-point indication can be routed to
2 binary inputs so that the open and closed circuit-breaker switch positions can be reliably acquired.

Signal Type Description
Position 3-pole
DPC Acquisition of the 3-pole circuit-breaker switch position.
The position 3-pole circuit breaker open and/or the position 3-pole
circuit breaker closed can be acquired by routing to 1 or 2 binary
inputs.
