Step is defective
Check the capacitor steps;
fuse, capacitor or contactor
may be defective.
Set the step type back to
“AUTO” after the cause has
been eliminated in order to
reset the alarm. The control
can use the steps again for
the control.
Steps are not switched on
Steps are too big
The necessary reactive
power is less than the
switching threshold of the
step power of the smallest
capacitor step.
Check
ΔQ in the
measurement value menu.
Check the dimensioning of
the system. The gradation
of the step sizes may be
too rough or the step sizes
may be oversized.
No steps may be switched in the
manual mode.
Steps are locked, because
U-Alarm is active or the
discharge time of the steps is
still running.
Steps have been switched off
due to the THD-U, THD-I or
TEMP2 alarm and have been
locked for 30 min.
LIFO, combi filter or FIFO
has been set as control
algorithm.
Check if the measuring
voltage is within the valid
range and if the U alarm is
signalled, enter the set
nominal voltage again, if
necessary.
After a restart of the control,
wait for the set discharge
time lock and try again.
If steps have been switched
off due to the
THD-U, THD-I or TEMP2
alarm, wait for the blocking
time of 30 min.
In order to test the steps,
use the control algorithm
