Due to the switching-out of capacitor steps, it may be that the set power factor cannot be maintained.
This may cause reactive power costs.

6.3.15. Parameter
-15-
: Permitted maximum temperature
By means of an internal sensor, the
ESTAmat PFC
Controller can measure the ambient temperature.
When the preset maximum temperature is exceeded, the display of the fault alarm
≡
T
alternates with
the display of the actual power factor.
Advice: If for parameter
-13-
(function of the alarm relay) the value
6
has been selected, a cabinet
ventilator can be switched in via the alarm relay.

6.3.16. Parameter
-16-
:Current factor RMS current/fundamental frequency current
This factor indicates the relation between fundamental frequency current (50Hz or 60Hz) and root-
mean-square current. The higher this factor the greater is the portion of harmonic waves. This way, the
harmonic situation can be evaluated. Factors between
1.05
and
2.00
can be set. The step width is 0.05.
If the factor is exceeded, the fault alarm
≡
IEF
will be given after a time delay of 5 minutes. With the
setting
OFF
, this function is switched out.
If
RST
is selected (see page 20),
OFF
is reset.
