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 380 VAcExtPhsFailS1 1 The line conductors of the
measured AC voltage at
connections VExt and AC2
do not match.
• Ensure that the neutral conductor and line
conductor are correctly connected to the
connection ExtVtg.
• Ensure that the neutral conductor and line
conductor are correctly connected to
connection AC2.
• Ensure that the connections ExtVtg and
AC2 are connected to the same line
conductor.
W 381 VAcExtPhsFailS2 1
W 383 HotAcBusSlv1 1 When the tie switch is open,
AC voltage from an
unknown source is present at
connection AC2.
• Ensure that the triggering of the tie switch
is correct.
• Ensure that the tie switch is correctly
wired.

W 401 GnRevPwrProt 1 AC sources in the
system are driving the
generator. The reverse
power in the generator
has been exceeded for
too long.
• Adjust the generator request to the properties of the
AC sources in the system and the loads, e.g., for PV
inverters preferably request the generator at night.
•
If the generator can absorb reverse power, adjust
the settings for reverse power (see the Sunny Island
inverter installation manual).
