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.

The controller is supplied as standard for an operating voltage of 110...440 VAC (+-10%),
a measuring voltage of 30...440 V~ (L-N) resp. 50...760V~(L-L) and a measuring current
of 5A or 1A. A voltage converter is required for different operating voltages.
Caution!
Voltages which exceed the specified voltage range can damage the
device !

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
Example :
Meas.current: L1
Meas. voltage: L3-L2

Section 4 Automatic operation - display of network parameter
The device is set to automatic operation as standard (not AUTO-INIT). Capacitor stages
are then automatically connected in or out in order to reach the target power factor. This
happens if the required reactive power is approx. 1/3 higher than the value of the
smallest capacitor step.
In automatic operation, various network parameters can be displayed by repeatedly
pressing the "ENTER” key:

The power value specifies the total power (3-phase) assuming symmetrical load. If no
key is pressed for 120 seconds, the display automatically returns to the operating status!

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.
