Symbol Type Description Reaction of ESTAmat PFC Fault elimination
≡AUI
fault during
initialization
mode AUI
AUI could not be completed
without faults
five trial runs are made
- Controller cannot determine the C.T. location easily owing
to the quick load changes
≡AU2
fault during
initialization
mode AU2
AU2 could not be completed
without faults
five trial runs are made
- Controller cannot determine the C.T. location easily owing
to the quick load changes
≡SLE
stand by
mode
SLEEP
AUI and AU2 have appeared five
times in succession. This
condition is changed only upon
fundamental change of load
none
- automatic initialization is not possible due to the actual
load condition. Upon change of the line conditions, the
Controller tries again an initialization. It is recommended
to change to AU3
≡E
feeding back
of energy
the display appears when
capacitor steps shall be
switched out in case of feeding
back of energy
capacitor steps are switched
out after a certain delay, if
the function is activated
- No fault function!
≡IEF
current rms
value
the relation between rms value
and fundamental frequency
value of the current has
exceeded a specified limit
capacitor steps will be
switched out one by one after
five minutes, if the function
is activated
- due to harmonic currents, the rms current may clearly
differ from the fundamental frequency current. The
increased harmonic current may lead to overloading of the
capacitors. Dangerous resonance conditions can be
temporarily avoided by switching out capacitor steps.
However, the harmonic current situation will have to be
examined.
≡HAR
harmonic
current
a specified percentage of a
harmonic has been exceeded
none
- dangerous resonance conditions can be temporarily
avoided by switching out capacitor steps. However, the
harmonic current situation will have to be examined.
≡PAR
parameter
control
by the first start-up procedure,
the parameters -4- and -5- must
be verified.
after a delay of 2 seconds,
the controller will
automatically change to the
setting menu of the
parameter concerned.
- No fault function!
