Signal Type Description
>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.
Circuit-Breaker Tripping Alarm Suppression
Circuit-Breaker Tripping Alarm Suppression
In certain systems, the user may wish to actuate an alarm (for example, a horn) when tripping (circuit-breaker
tripping) occurs. This alarm should not to be issued if the circuit breaker is to be reclosed automatically after
tripping or if it is to be closed or opened via the control. The alarm is only to be issued in the event of final
tripping.
Depending on how the alarm is generated (for example, triggered by a fleeting contact of the circuit breaker),
the Alarm suppression signal can be used to suppress the alarm.
The signal is generated if:
•
A definitive protection tripping is not present
•
The automatic reclosing function executes a closure
•
The integrated control executes a closure or opening action
•
External closing is detected via the Manual close function
For further information about its use, please refer to 5.5.9.2 Application and Setting Notes.
