Corrective measures
W 372 VtgFrqRatio
1
Disconnection from the external
grid or generator due to non-
compliance with the voltage-fre-
quency ratio at line conduc-
tor L1 (Master)
• Contact the Service, if required (see
Section 16 "Contact", page 161).
W 373 VtgFrqRatioSlv1
1
Disconnection from the external
grid due to non-compliance with
the voltage-frequency ratio at
line conductor L2 (slave 1)
W 374 VtgFrqRatioSlv2
1
Disconnection from the utility
grid due to non-compliance with
the voltage-frequency ratio at
line conductor L3 (slave 2)
F 376 ExtCtcNotClose
3
Tie switch does not close.
• Ensure that the triggering of the tie
switch is correct.
• Ensure that the tie switch is correctly
wired.
• Ensure that the feedback contact is
correctly connected.
W 377 ExtCurExCeed
1
The external current measured
on L1 exceeds the set parame-
ter value
232.04 GdCurNom
or
234.03 GnCurNom
by 2%.
• Reduce power consumption of all
loads.
• Reduce power output of the AC
sources (e.g. PV inverter).
W 378 ExCurExcSlv1
1
The external current measured
on L2 exceeds the set parame-
ter value
232.04 GdCurNom
or
234.03 GnCurNom
by 2%.
W 379 ExCurExcSlv2
1
The external current measured
on L3 exceeds the set parame-
ter value
232.04 GdCurNom
or
234.03 GnCurNom
by 2%.
W 380 VAcExtPhsFailS1
1
Phase position of the measured
AC voltage at
VExt
and
AC2
does not match at line conduc-
tor L2 (slave 1).
• Ensure that the neutral conductor
and line conductor are correctly
connected to connection
ExtVtg
.
• Ensure that the neutral conductor
and line conductor are correctly
connected to connection
AC2
.
• Ensure that connections
ExtVtg
and
AC2
are connected to the same
line conductor.
W 381 VAcExtPhsFailS2
1
Phase position of the measured
AC voltage at
VExt
and
AC2
does not match at line conduc-
tor L3 (slave 2).
