Uni-line - DEIF Wind Power Technology

If -P> relay is chosen to -5% - 10 s do this:
Set current input to 7.5% of nominal input
Cos(ϕ) = -1: Yellow -P>5/10% is lit immediately, and the -P>5/10% relay is activated after 10 s.
If -P> relay is chosen to -10% - 5 s do this:
Set current input to 12.5% of nominal input
Cos(ϕ) = -1: Yellow -P>5/10% is lit immediately, and the -P>5/10% relay is activated after 5 s.
LSU-114DG:
Setting: T N: 100 ms
X P: 40%
Freq: Nominal frequency (50/60 Hz)
Derating: 0%
Connect nominal supply voltage:
Connect nominal measuring voltage
in the right coupling (1W, 1W3 or 1W4)
Adjust Freq potentiometer until no ▲-
or ▼-SG pulses:
Adjust Freq potentiometer to nominal
frequency -1 Hz:
Connect 50% of nominal current to
IL1 input
Cos(ϕ) = 1
Measure the voltage on the PS terminals:
Adjust input current to 100%:
Green “Power” LED is lit.
Green U G LED is lit.
Yellow P setpoint on LSU-113DG is not
correct:
EPN-110DN:
Settings:
Don’t care
Connect nominal supply voltage:
Short-circuit ▲-input:
Short-circuit ▼-input:
Jumper setting is not correct.
Green “Power” LED is lit.
Yellow ”▲” LED is lit while the input is short-circuited.
Yellow ”▼” LED is lit while the input is short-circuited.
Possible fail in EPN-110DN:
No light in “Power” LED:
Relay functions are not correct:
(Energised/de-energised/latch)
Wrong auxiliary voltage module is mounted, or it is not mounted correctly.
Jumper settings for relays are not set correctly.
DEIF A/S reserves the right to change any of the above.
