Section1 General
The power factor controller Prophi 12 (single phase) enlarges the product range of power
factor control devices by a useful combination of the well known features with the
advantages of a better visualization.
The big graphic display enables a user-friendly programming and gives further benefits
such as larger display in the Display-mode and the display of various parameters in
bargraph-mode.
With the additional “ESCAPE”-button a backward navigation in all menus is possible.
The “HELP”-button allows an interactive help in the particular menu item
(German/English).
The controller is characterized by its user friendly operating interface via menu driven
plain text display. The display of several grid parameters, the storage of different values
as well as the possibility of test run allow a simple error analysis and system monitoring.
If required, an automatic initialization is possible which reduces the start-up operation to
a minimum.

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 device 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
2
position. The measuring-current circuit must be wired with copper leads of 2.5mm . The
connection should be set up as shown below. The specified safety regulations must be
observed.
The measuring voltage may lie in the range from 30...440 V~ (L-N) resp. 50..760V~ (L-L)
(programming of phase correction needed)
The operating voltage is 110...440 VAC +/- 10%.
The coil voltage for the capacitor contactors and the measuring voltage
must be drawn from the same phase conductor, as only the measuring
voltage is monitored. (Protection against direct reconnection of the
capacitor contactors in the event of momentary single-phase power
failure)

2.1 Current measurement
When installing the current converter, care should be taken to ensure that the load
current and capacitor-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.
2.2 Programming of phase-correction - e.g. connection directly L-L (400V)
Adjustment of phase-correction between voltage and current in the meas. system is done
in expert mode 1

5.1. Automatic initialization
available only, if in ExpertMode 2: „2 Auto-Init = YES“
With the automatic initialization the PROPHI 12 will automatically recognize the
parameters of the PFC-system. It also serves as plausibility check and storage of these
parameters - the user only has to make very little or even no adjustments.
Start of the initialization process is done from the menu point “PROGRAMMING” by
pressing the button “ ”
AUTO-INIT [YES] to be confirmed with pressing the ENTER button.
Now either the values of the current transformer OR the value of the smallest step of the
system have to be keyed in. The input of one of these values is absolutely mandatory.
After input (confirm with ENTER) the automatic test run of the controller is executed.
é
3 test-runs will be performed during which all stages are being switched on and off. All
necessary parameters are collected, evaluated and stored. Under certain circumstances
3 additional test-runs may be required for a proper initialization.
After successful finalization of AUTO-INIT the device will switch to normal operation.
In case of recognition of any discrepancies (plausibility) or of inaccurate connection, the
detected error will be displayed in plain text after finalization of AUTO-INIT and can be
eliminated. (see possible error messages at the end of the manual). AUTO-INIT may be
repeated then.

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.
Manual operation 1: The starting condition is STOPP (no stages connected).
Connections are made by pressing the é key (CAP ON).
Pressing ê initially leads back to STOPP mode.
Repeated pressing of ê leads to the disconnection of stages (CAP OFF).
The active operating status and active power factor are always shown on the display.
Pressing ENTER takes the user to the Manual operation 2.
Normally, all stages are programmed for automatic operation (default setting).
Here all controller outputs (C1 - C12) may be permanently defined in succession
(continued switching via ENTER) for the following statuses:
FIXED: The output is continuously connected, e.g. for fixed PFC. The output is
marked by an underlined capacitor symbol.
AUTO: Automatic (normal) operation
The relevant output is marked by a capacitor symbol.
OFF: The output is continuously disconnected - e.g. for temporarily disconnecting a
defective capacitor. The capacitor symbol for this output is faded out. Minus ( - )
appears.
ON: The selected stage will be switched ON (maybe putting into operation)- in case
a discharge-time is active - it will be shown at the display
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 7 Service menu
The service menu is reached by the operating-mode key.
The stored maximum values of the network parameters can be displayed here as well as
the number of switching operations of the individual capacitors and their operating time.
The desired stages [in square brackets] can be selected via the arrow keys.
* In Version /RS the max.values are stored including time-stamp!
In addition, a fault memory is available, in which the last 50 fault states of the system are
stored with fault code and in plain text. (This allows, for example, capturing short lived
events of overtemperature or overvoltage)

TEST-RUN
This menu point allows the user to check the settings of the PFC controller. After activation
of the test run, the controller switches each stage ON and OFF successively and calculates
the output of the capacitors connected (this procedure is done three times to eliminate
possible errors). The values calculated are stored and can be retrieved in the following
menu item (C-POWER). At the same time, a plausibility check is conducted with the values
programmed. Discrepancies are displayed in plain text afterwards. The following errors
can be displayed:
- No measuring voltage
present
- Measuring voltage too high - check programming
- Measuring voltage too low - check programming
- No measuring current? - Short circuit link in current transformer?
- Phase angle current transformer? k/l or phase transposed ?
- Current transformer ratio / 1. step power wrong ?
- Control series? - check programming
- End stop? - check programming
- Capacitor defect or wrong power input
Note: The results displayed are messages intended to help the user trace the cause of the
error. Final evaluation remains the responsibility of the user. Under complicated (high load
fluctuations) grid conditions, 100% error recognition cannot be guaranteed.

Section 9 Control principle
The control response of the device can be selected in programming mode.
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 controller 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.
The particular capacitor steps are permanently monitored. In case of a defect
capacitor or higher deviation from the nominal output the capacitor will be
displayed inverted.
