30 FAULT
FUNCTIONS 1 = 1
30.02 EARTH FAULT B WARNING (0) WARNING A warning is given in an earth fault condition. 1 = 1
(1) FAULT Converter trips in an earth fault. 1 = 1
30.03 EARTH FAULT
LEVEL
R 4 Non-parallel connected conveters (frame sizes
R8i, R9i, R10i, R11i and R12i): This parameter
sets the earth fault trip level through the PPCC
link.
Parallel connected converters (frame sizes
2xR11i, 2xR12i, 4xR11i, 4xR12i): current
unbalance protection of converter output, e.g,
in a short-circuit. 1 = 1
1 1 % unbalance in the sum current
2 3 % unbalance in the sum current
3 8 % unbalance in the sum current
4 13 % unbalance in the sum current
5 18 % unbalance in the sum current
6 28 % unbalance in the sum current
7 39 % unbalance in the sum current
8 62 % unbalance in the sum current
30.04 EXT EARTH
FAULT
I NO Earth fault detector is connected to digital input
DI4. This parameter selects the converter
reaction. 1 = 1
(1) NO Not in use
(2) DI4=0 FAULTS Converter trips on EARTH FAULT if DI4 is OFF
(0).
(3) DI4=1 FAULTS Converter trips on EARTH FAULT if DI4 is ON
(1).
(4) DI4=0 ALARMS A warning is given if DI4 is OFF (0).
(5) DI4=1 ALARMS A warning is given if DI4 is ON (1).
30.05 EXT EVENT I NO This parameter selects the converter reaction
to the state of digital input DI5.
(1) NO Not in use
(2) DI5=0 ALARMS A warning is given if DI5 is OFF (0).
(3) DI5=0 FAULTS Converter trips if DI5 is OFF (0).

Intermediate circuit DC overvoltage trip limit.
The lower range limit is determined by Par.
30.12 DC UNDERVOLT TRIP. When the
setting of this parameter is changed, the
corresponding higher range limit of Par. 30.12
DC OVERVOLT TRIP will also change. 1 = 1
