NOMINAL VOLTAGE = PHASE - PHASE
100...241500 V
Function of the setting of nominal voltage is to make a definition
about the nominal voltage of the system. The threshold levels for
under- and overvoltage are based on this as well as the ratings of the
capacitor sizes in step database, which are used for control and
monitoring. The capacitor sizes, which are stored in step database,
are also rated to the nominal voltage.
Ct
CT-FACTOR
1...9600
The CT FACTOR is the ratio of current transformer.
(e. g. 1000/5 = ratio 200).
At devices with software version 1.04 is the adjustment range from
1-4000.
Pt
VT-FACTOR
1...350
VT FACTOR is the ratio of the voltage transformer.
If the regulator is connected directly to the measurement voltage
without VT the value 1 has to be used.

AUTO-INITIALIZING START
Yes/No
"YES" starts auto-initializing
Automatic initialization is switching all exits. During this test it can
get information, which exits are working and it can correct the
connection of the measuring channels for voltage and current by
internal
settings.
Automatic initialization can be started only when the voltage and
current are ok. Steps with step type "FON" or "AL" will be not
considered in case of new auto-initialization.
AUTOMATIC INITIALIZATION is only able to work, when capacitors
are used for compensation. If BLR-CX has to switch reactors for
compensation of capacitive load, this feature will cause failures. AI
is working at best, when there are stable load conditions!
At devices with software revision before 1.04, stages which are set
to "FOFF" were not retested.
