Parameterisation Error
Changes made in settings during allocation of binary inputs and outputs or during assignment of measuring
inputs, may lead to inconsistencies endangering proper operation of protective and supplementary functions.
The device 7UT6x controls the settings for consistency and announces any inconsistent settings. For instance,
earth fault differential protection cannot be applied if there is no measuring input for the starpoint current
between starpoint of the protected object and the earthing electrode.
These inconsistencies are output with the operational and spontaneous annunciations.
