Signal Type Description
Position 1-pole
phsA
DPC Acquisition of the 1-pole circuit-breaker switch position for phase A.
The position 1-pole circuit-breaker phase A open and/or the position
1-pole circuit-breaker phase A closed can be acquired by routing to 1
or 2 binary inputs.
Position 1-pole
phsB
DPC Acquisition of the 1-pole circuit-breaker switch position for phase B.
The position 1-pole circuit-breaker phase B open and/or the position 1-
pole circuit-breaker phase B closed can be acquired by routing to 1 or
2 binary inputs.
Position 1-pole
phsC
DPC Acquisition of the 1-pole circuit-breaker switch position for phase C.
The position 1-pole circuit-breaker phase C open and/or the position 1-
pole circuit-breaker phase C closed can be acquired by routing to 1 or
2 binary inputs.
The signal or signals must be routed to the binary inputs that are connected to the circuit-breaker auxiliary
contacts. The open and closed signals do not necessarily have to be routed in parallel. The advantage of
parallel routing is that it can be used to determine an intermediate or disturbed position. On the other hand,
this is not possible if only one signal is routed.
In the monitoring direction, the position signals generate the following information when the open and
closed positions are detected (see following table). This information is further processed by the Circuit-
breaker position recognition and Control function blocks.
Information Type Description
Off SPS Circuit-breaker switch position is opened.
On SPS Circuit-breaker switch position is closed.
Intermediate position SPS Circuit-breaker switch position is in intermediate position.
Disturbed position SPS Circuit-breaker switch position is in disturbed position.
Not selected SPS The circuit breaker is not selected for a control operation.
Other input signals are:
Signal
Type Description
>Acquisition
blocking
SPS This is used to activate acquisition blocking of the circuit-breaker auxil-
iary contacts (see chapter Other functions 3.8.3 Persistent Commands
for a description of acquisition blocking).
>Ready
SPS The active signal indicates that the circuit breaker is ready for an OFF-
ON-OFF cycle.
The signal remains active as long as the circuit breaker is unable to trip.
The signal is used in the Automatic reclosing and Circuit-breaker test
functions.
Another output signal is:
External health
SPS This can be used to indicate the health of the physical circuit breaker.
For this, you must acquire any failure information for the circuit breaker
via a binary input. This failure information can set the appropriate state
of the External health signal with a CFC chart (using the
BUILD_ENS block).
The signal has no effect on the health of the function block.
Definitive Tripping, Circuit-Breaker Tripping Alarm Suppression
Definitive Tripping
Definitive tripping is always pending whenever the Automatic reclosing (AREC) function does not carry out
any reclosing after tripping. It follows that this is the case whenever an automatic reclosing is not present or
the AREC has been switched off.
