Value
110 %VT
RANGE: 100
149
STEPS: 1
Enter the percentage value at which the faulty condition for OverVoltage1 drops
out. At this point, it is possible to reset the VFR manually by pressing the Reset
button.

Voltage Protect.
OverVoltage1 Phase
Operat.
Value
ANY ONE
RANGE: ANY ONE; ANY TWO; ALL THREE
Select the minimum number of phases on which the faulty condition has to occur
for OverVoltage1 intervention.

If OverVoltage1 Relay
≠
NONE
Voltage Protect.
Phase Reversal
Relay
Value
- - - - - - - -
(*)
RANGE: NONE; ANY COMBINATION OF AUX1, AUX2, AUX3, AUX4, AUX5,
AUX6, AUX7 OR AUX8
When NONE is selected, the protection Phase Reversal will be disabled.
The protection will activate when the relay detects the voltage sequence as
inverse.

UnderFrequency1
Relay
Value
- - - - - - - -
RANGE: NONE; ANY COMBINATION OF AUX1, AUX2, AUX3, AUX4, AUX5,
AUX6, AUX7 OR AUX8
When NONE is selected, the protection UnderFrequency1 will be disabled.
Frequency Protect.
UnderFrequency1 Level
Value
59.0 Hz
RANGE: 47.0
59.9
STEPS: 0.1
Enter the UnderFrequency1 intervention level.
The protection will activate when the frequency drops below this value for a period
>= UnderFrequency1 Delay value.

If UnderFrequency1 Relay
≠
NONE
Frequency Protect.
UnderFrequency1 Reset
Value
59.2 Hz
RANGE: 47.1
60.0
STEPS: 0.1
Enter the value at which the faulty condition for UnderFrequency1 drops out. At
this point, it is possible to reset the VFR manually by pressing the Reset button.
