Measuring voltage or current has been connected at a twisted angle of 180° from the direction of
connection (U2 / U1 instead of U1 / U2 resp. S2 / S1 instead of S1 / S2).
Solution:
Correct the connection, execute the
“Automatic initialisation (AI)” or add 180° to resp. subtract
180° from the set phase correction angle (SETUP/206) (new angle < 360°).
Please observe the separate notes at the end of the chapter for the setting of the phase
correction angle.

incorrect connection
Incorrect phase between measuring voltage and current. Please check the connection of measuring
voltage and current (phase, polarity).
Possible causes:
The set phase correction angle does not correspond to the connection of measuring voltage and current.
Solution:
Correct the connection, execute the
“Automatic initialisation (AI)” or manually set the phase
correction angle correctly.

The
“Automatic initialisation” (AI) was cancelled with error.
Possible causes:
Heavy load fluctuations during the
“Automatic initialisation (AI)”
Solution:
Restart the
“Automatic initialisation (AI)”, when the mains is steadier. The measuring current
was too small.
The current transformer ratio may be too large.
Solution:
Check if the selected current transformer corresponds to the system and change it, if necessary.
Restart the
“Automatic initialisation (AI)”.
The stage sizes are too small.
Solution:
Enter the phase correction angle (SETUP/206) manually and switch on the control again
(SETUP/100/PFC or SETUP/310).
If the
“Automatic initialisation” (AI) is not successful after further attempts, it is also possible to
set the correct phase correction angle (SETUP/206) manually. The stage outputs which are not
connected can be set manually (SETUP/100/OUt) to the stage type
“
FOFF
”.
The control must be manually switched on again (SETUP/100/PFC or SETUP/310).
