(SETUP/205), correct it, if
necessary (depends on the
set nominal voltage)
Incorrect display of the current
Incorrect current transformer
ratio has been set.
Check the setting of the
current transformer ratio in
the SETUP menu
(SETUP/100/Ct resp.
SETUP/202), correct it, if
necessary.
The active power factor,
active and reactive power,
missing reactive power for the
control target are displayed
incorrectly.
The automatic initialisation
has not been executed.
The automatic initialisation
was cancelled with error.
The phase correction angle
was set incorrectly or
identified as incorrect by the
AI.
Offset reactive power
(Q offset) is set.
Start the automatic
initialisation
"SETUP/100/AI resp.
SETUP/207)" in the SETUP
menu.
Or check the phase
correction angle
(SETUP/206) in the SETUP
menu, correct it, if
necessary.
A transformer is also
compensated by the
compensation system. The
displayed COS
corresponds to the COS
upstream of the
transformer.
If there is no reason for a
set Q offset, check the
setting of the
Q offset (SETUP/312), set it
to 0 var, if necessary.
The power factor does not
change after switching one or
several steps.
Steps are switched off again.
The current transformer is
positioned incorrectly.
(Current transformer installed
downstream of the exit to the
compensation system
the
controller only sees the load,
thus there is no reactive
power change in the supply
line.)
Steps are defective.
Check the installation
position of the current
transformer according to
the wiring diagram (the
transformer must be
installed upstream of the
exit to the compensation
system, so that the current
of the load and of the
compensation is recorded),
correct it, if necessary.
Check the capacitor steps;
fuse, power contactor or
capacitor may be defective.
