6.3.1. Parameter
-1-
: Modes of initialization
Three modes of initialization are possible:
Initialization mode
Display
Fully automatic
AU1
Semi-automatic
AU2
Manual
AU3
If
RST
is selected (see page 20),
AU1
is reset.
•
Fully automatic initialization
AU1
The
ESTAmat PFC
Controller
determines the current transformer location, the output and
number of capacitor steps, and the switching program.
•
Semi-automatic initialization
AU2
The
ESTAmat PFC
Controller
determines, after the current transformer location has been set,
the output and number of capacitor steps and the switching program.
•
Manual initialization
AU3
The operator will have to set the current transformer location, the output and number of capacitor
steps, and the switching program.
6.3.2. Parameter
-2-
: Type of measuring voltage
The type of measuring voltage determines whether the measuring voltage is connected between phase
to phase or phase to neutral. Since this information is required only for the initialization mode
AU1
,
this
parameter will only be displayed in case
AU1
has been selected.
