NO
: The
ESTAmat PFC
Controller
takes over the stored C.T. location and starts with part 2 =
determination of the currents of the capacitor steps.
YES
: The
ESTAmat PFC
Controller
erases the stored C.T. location and performs part 1 and part 2
of the initialization
AU1
4.4.2. Semi-automatic initialization
AU2
The semi-automatic initialization
AU2
should be selected when the fully automatic initialization does
not produce a satisfying result due to strong load changes. Attention will have to be paid to the fact
that the phase connection of the measuring voltage has to be explicitly specified. Refer to items 6.2
and 6.3.2.
The initialization runs in accordance with part 2 of the initialization mode
AU1
(item 4.4.1.2).
4.4.3. Manual Initialization
AU3
In case of manual initialization
AU3
, the operator must set:
-
measuring voltage connection (parameter
-3-
, item 6.3.3.),
-
the type of switching program (parameter
-4-
, item 6.3.4.),
-
the C/k value
(parameter
-5-
, item 6.3.5.) and
-
the number of steps
(parameter
-6-
, item 6.3.6.).
The procedure to set the parameters is described under item 6.2.
During the first start-up procedure, parameters
-4-
and
-5-
must be verified. For this, both parameters
must be called-in and, if necessary, be modified in the setting menu. If this is not done
≡
PAR
will be
displayed, and after a delay of 2 seconds, the controller will automatically change to the setting menu
of the parameter concerned.
The step outputs will be determined by means of the C/k value, the number of switching steps and the
switching program. No readjustment of the step outputs will occur while switching the capacitor steps
during operation.
4.5. TEST MODE
During the start-up procedure of the controller,
if the measuring current
≡
I
, or the measuring
voltage
≡
U
is missing
, a test mode can be activated to switch steps in the manual operating mode.
During AU1 and AU2, the switching program of 1:1:1:1, the C/k value of 0.05 and the maximum
number of switching steps are automatically preset. Only during AU3, the already set parameters (4, 5
and 6) will remain. The test mode is activated by means of the key
.
Thereafter, the selected menu is displayed alternately with
TEST
.
For deactivation of the test mode, the
operating voltage of the controller must be disconnected. For example, this can be achieved by
temporarily removing the control fuse of the capacitor bank.
