You use the Blk. by meas.-volt. failure parameter to control the behavior of the function when a
measuring-voltage failure is detected.
A measuring-voltage failure can only be detected if one of the following 2 conditions is met:
•
The device-internal supervision function Measuring-voltage failure detection is configured and
switched on.
•
The binary input signal >Open of the function block VTCB is connected to the voltage-transformer circuit
breaker (see chapter 9.3.4.1 Overview of Functions).
Parameter Value Description
yes
The protection function is blocked (= default setting). Siemens recommends
using the default setting.
no
The protection function is not blocked.
