Blocking of Stage in Case of Measuring-Voltage Failure
The stages can be blocked if a measuring-voltage failure occurs. In the event of blocking, the picked up stage
will be reset. The following blocking options are available for the stage:
•
From an internal source on the pickup of the Measuring-voltage failure detection function
•
From an external source via the binary input signal
>Open
of the function block Voltage-transformer
circuit breaker, which links to the trip of the voltage-transformer circuit breaker
The
Blk. by meas.-volt. failure
parameter can be set to either block or not block the stage when the
Measuring-voltage failure detection function picks up.
