Phase-offset
0...345
This menu contains the correction angle for current and voltage
measurement determined during the auto-initialization. This value
should not be changed, because then the control not longer works
correctly.
Is auto-initialization failed due to adverse network conditions, by
hand a correction angle can be set or the incorrectly recognized can
be corrected. Table 11.1 gives an overview of the connection options
with corresponding phase angles.
207
Start auto-initializing
Yes/No
YES" starts auto-initializing
"NO" nothing happen
If the auto-initializing starts, the controller is testing all step's with
step type "AUTO" and "FOFF" again and the step type is newly
stored in the step database. Steps that are programmed to "FON" or
"AL" will be not considered in case of new auto-initialization.
At devices with software revision before 1.04, stages which are set
to "FOFF" were not retested.
208
Auto-initializing by regulator restart
Yes/No
"YES" The controller starts after every restart the countdown to the
auto-initialization.
"NO" The control starts after restart with the saved values.
209
Frequency synchronization
Auto/Fix50/Fix60
For the highest accuracy of measurement, the samples need to be
synchronized to the grid frequency.
Strong voltage commutation notches can, in spite of the internal
filtering, result that automatic synchronization is disturbed.
This could result in large measurement errors. For this reason the
following settings can made.
Automatic synchronization:
For maximum accuracy at mains voltage without commutation
notches.
FIX-50HZ
: For safe operation in the 50Hz grid with extremely poor
power quality.
FIX-60HZ
. For safe operation in the 60Hz grid with extremely poor
power quality.
210
Temperature offset (from software revision 1.04)
-10-10°C
This menu allows the setting of an additional temperature offset to
correct temperature dependent deviations of the components.
