The dynamic power factor controller Prophi-6T represents the consequent development
of the Prophi-series with new innovative ideas and a multitude of functions.
It has been especially designed to control thyristor modules for dynamic switching of
power capacitors for power factor correction (for example TSM-LC or similar). By using a
very fast type of processor, it has been possible to obtain extreme short switching cycles
which allows the usage for dynamic power factor correction.
In addition to a switching time of <20 ms, the intelligent control principle provides an
extremely fast tuning of the power factor by simultaneous switching of several steps.
Several parameters that can be edited allow an optimized adjustment to different
thyristor modules.
The device is distinguished by user-friendly operation based on menu-guided displays in
plain text. Its new features permit an intuitive mode of operation. Easy-to-understand
symbols and texts in 10 local languages combine simplest operability with self-evident
displays.

Section 2 Installation and connection of the controller
The device is designed to be incorporated into the front panel of a PFC-cabinet. It requires
a switchboard section of 138 x 138 mm to DIN 43700/ IEC 61554. The controller is
inserted from the front and is attached by means of the appended clamps. The
controller may be inserted only by qualified technicians and must be operated in
accordance with the specified safety regulations.
Before the controller is connected up, all leads and cables must be checked to ensure that
no current is flowing through them and the current converter must be short-circuited.
Care should be taken to ensure that the measuring voltage and current are in the correct
phase position. The measuring-current circuit must be wired with copper leads of
2
2.5mm . The connection should be set up as shown in Fig. 3. The specified safety
regulations must be observed.
The measuring voltage may lie in the range from 30- 525 V and can be connected between
L - N (default) or between L - L. (programming of phase correction needed).
The operating voltage is 110...230 V +/- 15% and can be connected between L - N or L-L.

2.1 Current measurement
When installing the current converter, care should be taken to ensure that the load
current flows through it. The outputs of the compensation network must be installed
behind the current converter (in the direction of current flow). If the device is connected
up via sum-current converters, the overall conversion ratio is entered.

Section 6 Manual operation (initial operation, maintenance, service)
Programming of fixed stages
In manual operation, capacitor branches can be connected/disconnected in the set
control series and switching time - irrespective of prevailing power-line conditions.
The starting condition is STOPP (no stages connected). Connections are made by
pressing the é key. Pressing ê initially leads back to STOPP mode. Repeated pressing of
ê leads to the disconnection of stages. The active operating status and active power
factor are always shown on the display (self-explanatory).
Pressing ENTER takes the user to the menu point "Programming of fixed stages”.
In the normal case, all stages are programmed for automatic operation (default setting).
In special cases, all controller outputs (C1 - C6) may be permanently defined in
succession (continued switching via ENTER) for the following statuses:
OFF: The output is continuously disconnected - e.g. for temporarily disconnecting a
defective capacitor. The capacitor symbol for this output is faded out. Underlining
appears.
AUTO: Automatic (normal) operation
The relevant output is marked by a capacitor symbol.
FIXED: The output is continuously connected, e.g. for fixed PFC. The output is
marked by an underlined capacitor symbol.
TEST:
The active stage is blinking. The required status is set via é /ê. By pressing ENTER, the
user saves this step and moves to the next stage.
The programmed statuses for the outputs also remain visible on the display in automatic
operation.
After the required settings have been made, pressing the "Operating Mode” key takes the
user to the next menu ("Service”) or further to "Automatic Operation”.

Section 9 Control principle
The control response of the Prophi-6T can be selected in programming mode. In principle,
the controller has four different control modes:
1. Sequential connection
In sequential connection, the required capacitor stages are successively connected
and disconnected in stages (last in - first out). The ranking of each step always
corresponds to the power of the smallest stage.
Advantage: Exact definition of the next capacitor to be connected in each case
Disadvantage: Long settling time, high switching frequency of the small stages
In order to shorten the settling time, the BR6000 switches several stages
simultaneously for a large power-factor requirement. This applies to all
control types. The maximum dimensions of the simultaneously switching
branches can be changed in expert mode. If the value of the smallest stage
is pre-selected, the conventional sequential connection is obtained.
2. Loop connection
In this variant, the controller operates in loop mode (first in - first out) which
minimizes the wear on the capacitor bank, i.e. where stages are of equivalent
dimensions, the stage which was disconnected for the longest period of time is
always connected next.
Advantage: Balanced utilization of equivalent stages and thus an increased
operating life of the capacitor bank.
Disadvantage: This mode can only be used in control series with groups of the same
stage power and long settling time, as every switching step corresponds to the value
of the smallest stage.
3. Intelligent loop connection (default setting )
The intelligent control principle combines the advantages of the network-sparing
loop connection (first in - first out) with a much faster settling time, even for large
load skips, and reaches this goal with the fewest possible switching operations of the
capacitor stages. The optimized time response is achieved by the simultaneous
switching of several or larger capacitor groups as a function of the missing power
factor in the power line. Both the number of real switching frequencies of the
capacitors as well as the turn-on times of the branches are considered.
Advantage: Reaches the target cos phi in a fast-optimized settling time with a low
switching frequency of the capacitors.
4. Combined de-tuning (special case for combined de-tuned banks)
Within a combined de-tuned application, 2 adjoining equal steps are switched with
just one joint choke. This pairwise de-tuning requires an appropriate closed control
series (i.e. 1:1:1:1..., 1:1:2:2..., 1:1:2:2:4:4... or similar)
The condition for the switching behavior is defined in such a way that the number of
activated odd steps is always greater than or equal to the number of activated even
steps. The controller complies with the requirements of the control regime while
largely conforming to the intelligent switching behavior.

Section 10 Initial operation
The controller must have been installed before being set up and operated.
All network-specific parameters are fully programmed as described in section 5
(Programming) by being entered in sequence and stored. The controller is then set to
automatic operation with the operating mode key. It is now ready for operation.
Section 11 Maintenance and warranty
The controller should need no maintenance if the operating conditions are observed.
However, it is recommended that a functional check of the controller be performed in
conjunction with the regular checking of the capacitor bank. In the event of any
interventions in the controller during the warranty period, all warranty claims lapse.

If a target cos phi is set which deviates from 1
despite an inductive line load, the display <
(disconnect stages) may light up. The arrows
indicate the control direction and not the line
conditions.
Check END STOPP !
Check whether individual stages are
programmed as fixed stages or OFF in the
"Manual operation / Fixed stages” menu!
Line measurements allow the most favorable
phase for measuring the power factor to be
determined. The current converter is set
accordingly for the measuring current.
Note: No display, alarm relay is activated

Control -series editor (programming up to a rating of 30)
The control-series editor allows the user to simply define his/her own control series if the
required control series is not available for any reason.
The last control series - Control Series E - is selected by pressing the "Programming” key
(point 4: Control series) and confirmed with ENTER. This leads to the insertion of an
additional menu point in the main menu -> the control-series editor. It may be reached
via the "Operating Mode” key.
In the control-series editor, all stages can be set in succession to the desired value with
the selection keys é / ê. The next stage in each case is reached by pressing ENTER.
In the control series editor, the various steps may be programmed up to a rating of 30 (!).
The rating >9 is indicated in the display as follows:
10=A, 11=B, 12=C, 13=D, 14=E, 15=F, 16=G .... 30=U
The maximum number of stages can be limited by a programmed END STOPP < 6
ALL control series can be generated (even downwards). The customer will decide
whether the generated control series is of sense.
