Section 1: GENERAL
The power factor controller Prophi-15T-III is the consequent follow-up development of
the well proven series Prophi.
The main distinctive feature is the new 3-phases measuring system. Due to the 3-phases
recording of voltage and current the device allows a convenient usage as grid measuring
device and as power factor controller.
All measuring values can be edited and may be displayed in big letters for easier
readability.
2 interfaces are standard. By means of the comfortable windows-software that is included
in the delivery and by using one interface for a connection to a PC the execution and
evaluation of grid measurements is possible. The second interface can be used for
customer specific purposes.
Used as PF-controller various control modes are available. They allow not only to control
according to the phase with the highest load or the average demand of the phases, but
also to realize a real single-phase control (balancing) or a mix of balancing and
conventional three-phases-control.
For an easy usage the concept of graphic menu navigation has mainly been adapted.
New are amongst others an integrated help (HELP-button) and the possibility to jump
back in the programming menu by an additional ESCape-button.
The usage of a fully graphic support display allows an additional Oscilloscope-Mode where
the phases (half waves) of voltage and current can graphically be displayed.

Section 2: INSTALLATION AND INSTRUCTIONS FOR USAGE
The controller is designed as panel mounting instrument in PFC-systems. This requires a
cut out of 138 x 138 mm according to DIN 43700 / IEC 61554. The controller has to be
inserted from the front and fixed with the clamps (included in delivery). The device may
only be installed by qualified personnel and may only be operated according the given
safety regulations. In addition the relevant legal and safety instructions have to be
obeyed.
The measuring input is designed for 1- and 3-phase grids.
The maximum measuring voltage is 440V~ (L-N) / 760V ~ (L-L).
The supply voltage is 110...230 V +/-15%.
Wiring connections must be suitable for the particular voltages. Input leads have to be
protected by over-current-protection devices. The supply voltage must be protected by a
fuse; it must be possible to switch off the supply voltage by a separator.
The device must not be operated without protective earth contactor connected!
Before connecting, it has to be checked that all connections are at zero potential; current
transformers have to be short circuited. Correct phasing of measuring voltage and
measuring current have to be checked. The measuring current circuits must be wired with
2
minimum 2.5 mm Cu.
Terminals may only be plugged when de-energized!
Attention!
The controller may only be operated when installed. The complete programming of all
application-specific parameters is done according chapter programming. Then the device
is set to automatic operation by pushing the operation mode button. The controller is now
ready for operation.
Operating the controller without following to these operating instructions may be harmful
and dangerous!

The controller is supplied for a standard operating voltage of 110...230VAC (+/-15%), a
measuring voltage of 30...440 V~ (L-N) resp. 50...760V~ (L-L), 50/60Hz, and a
measuring current of 5A or 1A (programmable). A voltage converter is required for
different operating voltages.
Caution!
Voltages which exceed the allowed voltage range can damage the
device !

Section 3: CONNECTION ALTERNATIVES MEASURING VOLTAGE
AND MEASURING CURRENT
According to the existing grid and the desired operating mode (CONTROL-MODE
Programming) the controller has to be connected accord. one of the following
alternatives. The separate auxiliary voltage (24 V DC) that is needed for the thyristor
switches has to be conducted to P1…P3 and to the connection “control 24V”. The
connection of PE is mandatory!
Alternative 1: measuring performed in each phase - 3 current transformers needed
Use: CONTROL-MODE: 1 - 4; 7-12; 15 (control modes see page 11)
Alternative 2: single-phase measuring via current transformer in L1 Values extrapolated (balance assumed).
Measuring complies with conventional measuring for switching of three-phase capacitors.
Use: CONTROL-MODE 5; 13; 14; 16
Alternative 3: single-phase measuring as alternative 2 , but with capacitor current measuring in the compensation
system for collection of real capacitor currents.
Use: CONTROL-MODE 6

Connection of current transformer / sum current transformer
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 controller is
connected up via sum-current converters, the overall conversion ratio is entered.
Caution!
The secondary clamps of the CT
have to be short circuited before
current leads are iterrupted !

High Voltage Application
The example shows the connection in HV-application.
The measuring current is taken off primary via X/1A transformer. Measuring voltage
produced via transformer 20000/100 V. In this case, the Prophi 15T-III has to be

Section 4: DISPLAY - FUNCTIONS
After the operating voltage has been switched on, the controller briefly indicates with
description and software-version before changing to automatic operation.
Actual values and symbols of the particular operation state are shown in the display.
In the automatic operation (standard) capacitor steps are automatically switched on or
off to reach the pre-set target cos-phi. This happens when the required reactive power is
higher than the value of the smallest capacitor step.

According variant 5, but the free current inputs (L2 or L3) are used for capacitor current
measurement for real monitoring of capacitors.
CONTROL-MODE 7 - 14: HYBRID-MODE
The connection of the outputs is done according the related switching diagrams MODE 1-4. In
Hybrid-Mode the Prophi 15T-III is connected with one or two controllers Prophi 12RS via the
system interface (Interface2). In this case the Prophi 15T-III takes over the dynamic part and
the Prophi 12RS takes over the slowly changing loads (s. application page 29).
CONTROL-MODE 15 - 16: COUPLING MODE
The coupling mode is used to couple 2 independent dynamic compensations systems which
are connected to each other via a coupling switch. The signal of the coupling switch is fed to
the master controller (s. application page 28).

example: changing of target cos-phi, switch-over of current
transformer or switch-over the switching times.
By triggering a 110...230V~ signal at the external input, the
2nd parameter set is activated with following values:

Section 7: HELP-Functions / actual output assignment
The Prophi 15T-III features a context related help function.
For each menu item one or more help pages are available which can be accessed directly
with the HELP-button. Scrolling is done with "UP/DOWN" buttons, back retrace with
ESCape.
In automatic operation (==AUTO-MODE==) 9 help pages are available. The first pages
explain the general meaning of used symbols.
On the help pages 7…9 the actual assignment of the internal transistor outputs
to the phases and to the capacitors are shown directly.
This table depends on the CONTROL-MODE that is set and will change
automatically.
The assignment shown here is not trivial, especially in CONTROL-MODE 2
(MIXED MODE) and must be obeyed without exeption!
