[Binary Flag (8 bits)]
Logic Settings that determine whether blocking signals from VT supervision affect certain earth fault overcurrent stages.
VTS Block - only affects sensitive earth fault protection. With the relevant bit set to 1, operation of the Voltage Transformer Supervision (VTS),
will block the stage. When set to 0, the stage will revert to Non-directional upon operation of the VTS.
