Operating Manual
Level Cause
2 The Sunny Island system discon-
nects from the generator or util-
ity grid due to a voltage imbal-
ance between the line conduc-
tors.
3 Phase position of the measured
AC voltage at VExt and AC2
does not match at line conduc-
tor L1 (Master).
3 When the tie switch is open, AC
voltage is present at line con-
ductor L1 (Master).
3 Tie switch does not open.
3 Neutral conductor relay does
not open at L1 (Master).
1 Neutral conductor relay does
not open at L2 (slave 1).
1 Neutral conductor relay does
not open at L3 (slave 2).
10 Troubleshooting
Corrective measures
• Eliminate any faults in the
installation.
• 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.
• Ensure that the triggering of the tie
switch is correct.
• Ensure that the tie switch is correctly
wired.
• Ensure that the triggering of the tie
switch is correct.
• Ensure that the tie switch is correctly
wired.
• Ensure that the feedback contact is
