with dead busbar and configuration: Reversed, the roles of the internal and external voltages are
reversed

10% hysteresis is applied to the minimum voltage condition: once reached, the condition is lost if
the voltage drops below 90% of the set limit

NOTE: all the thresholds have ±10% tolerance with the exception of:
• Voltage Delta; the tolerance is the higher value between: ±10% of the set threshold and 0.5%
Un (with Un > 220 V) or 1% Un (with Un ≤ 220 V)
• Frequency Delta; the tolerance is the higher value between ±10% of the set threshold and
0.02 Hz

NOTE: this is not a synchronism condition, but a parameter allowing
matching
a discrimination to be made between correct and incorrect

combinations of the Delta Frequency and Delta Phase conditions.
Owing to worst case latencies, the time that effectively elapses
before synchronism is recognized may be longer than the set time
(approx. 20 ms)
