7.4.2 Voltage blocking (P4)
You can use voltage blocking to define limit values for blocking the auto-
matic voltage regulation (AVR AUTO). This allows you to avoid unnecessary
tap-change operations in the event of strong voltage changes in the mains.
▪ Undervoltage blocking: Blocking is activated as soon as the measured
value is less than the limit value.
▪ Overvoltage blocking: Blocking is activated as soon as the measured
value is greater than the limit value.
