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.

2.3 Alarm output / error messages
The alarm contact is closed in normal operation and opens in the event of a fault. The
relevant fault is simultaneously shown on the display in plain text (alternating with the
standard display in automatic operation). The following fault messages are displayed:
UNDER-COMPENSATED Display and relay output
missing reactive power
OVER-COMPENSATED Display and relay output
OVERCURRENT Display and relay output
MEASURING VOLTAGE ? Display and relay output
OVERTEMPERATURE Display and relay output
OVERVOLTAGE Display and relay output
UNDERVOLTAGE Display and relay output
HARMONICS Display and relay output
Section 3 Operating modes
When the operating voltage is switched on, the device displays its designation and
software version, then changes to its normal operating status (automatic operation). The
active cos-phi value is always displayed in the upper line and the currently connected
capacitors are shown as symbols in the lower line (operating display).
Additionally several messages for different operation states are generated. An individual
adjustment resp. suppression of particular messages is possible in expert mode 2. During
suppression, the indication of the message in the display, a possible release via alarm-
relays and effects on the controlling process will be prevented.

Section 4 Automatic operation - display of network parameter
The controller is set to automatic operation as standard. Capacitor stages are then
automatically connected in or out in order to reach the target power factor. This happens
when the required reactive power exceeds the value of the smallest capacitor stage.
In automatic operation, various network parameters can be displayed by repeatedly
pressing the "ENTER” key:
Action Display
ENTER 1 LINE VOLTAGE in V
ENTER 2 APPARENT CURRENT in A / %
ENTER 3 REACTIVE POWER in kvar / %
ENTER 4 ACTIVE POWER in kW / %
ENTER 5 APPARENT POWER in kVA / %
ENTER 6 DIFF. kVAR TO TARGET COS
ENTER 7 FREQUENCY in Hz
ENTER 8 TEMPERATURE in °C / °F
ENTER 9 HARMONICS (3.-19.) V/%, I/%
ENTER 10 THD-V; THD-I in%

ENTER Return to: 1
The power value specifies the total power (3-phase) assuming symmetrical load. If no
key is pressed for 60 seconds, the display automatically returns to the operating status!

Switching outputs
The switching outputs are executed as
transistor outputs.
The transistor outputs are used via an
additional auxiliary voltage (10 - 24 VDC) for
a direct triggering of thyristor switches for the
dynamic power factor correction (i.e. TSM).
Max.current for a single output: 40mA

Section 5 Programming
Pressing the "Operating mode” key once takes the user from automatic operation to
Programming mode.
The upper display always shows the parameter and the lower one the set value. The
values are changed by pressing the é / ê keys. Subsequent pressing of the "ENTER” key
stores the value and takes the user to the next parameter.
To quit programming mode in any step, press the "Operating mode” key.
5.1. Program Menu
LANGUAGE SELECTION: This selects the language of the operating menu
(German, English, Spanish, French, Russian, Czech, Dutch, Polish,
Portuguese, Turkish)
1 I-CONVERTER PRIM: [ 5...13000]A
This selects the primary current of the current converter. Adjustment is
via the é / ê keys. Save and continue with ENTER
2 I-CONVERTER SEC: [ 5 or 1]A
This sets the secondary current of the current converter
Selection via é / ê. Save and continue with ENTER
3 END STOPP: [ 1...6 ]
By setting the end stopp, the number of active capacitor branches is
matched to the respective capacitor bank. This is done via the é / ê
keys. The visible symbols of the capacitors correspond to the connected
outputs. The maximum possible number of capacitor branches is pre-
set at the works (6 branches).
Save and continue with ENTER
4 CONTROL SERIES: [ 1...20 + E ]
The ratio of the capacitor branch power determines the control series,
the power of the first capacitor always being assigned the value 1. The
control series required for the compensation network is again selected
via the é/ê keys. If the required control series should exceptionally not
be present (Annex 1), the user may define a special one (control series
"E”).More on this point in the control-series editor in Annex 1.
Save and continue with ENTER
5 CONTROL PRINCIPLE: The control preference may be selected here:
SEQUENTIAL connection
LOOP connection
INTELLIGENT loop connection (default setting)
COMBINED CHOKE
See Section 9 for an explanation of the various control modes.

6 POWER 1. STAGE: [ 0.01 ... 255.99 ] kvar
To determine the controller's response sensitivity, the dimensions of the network's
smallest capacitor (stage 1) must be known. They are entered in two steps in kvar.
The integral kvar values (before the comma) are initially selected via the é / ê
keys and saved with ENTER. The positions after the comma are then selected,
again via the é / ê keys. If the response sensitivity is being undercut, a warning
will occur ( indication of “!” in the display )
Save and continue with ENTER
7 TARGET COS PHI: [ 0.3 ind ... 0.3 cap ]
By setting the target cos phi, the power factor to be attained via the PF correction
is defined. It is also set via the é / ê keys.
Save and continue with ENTER
10 CONNECTING TIME [ 20...1000]ms
This refers to the time between connecting the capacitors to increase the
momentary network capacitance. It should be noted that in practical operation the
real connection time is affected by the discharge time (locking time).
Default setting: 1000 ms
Selection is performed via the é /ê keys. Continue with ENTER
8 MEASURING VOLTAGE [ 30 ... 525] V
Programming the measuring voltage. The values programmed here always refer
to the voltage at the clamps of the device!
The voltage is selected via the é /ê keys. Save and continue with ENTER.
9 V - CONVERTER RATIO [ NO ] possible: 230V...380kV / Vmeas.
When a measuring-voltage converter (e.g. for HV- measurement) is used, its
conversion ratio should be programmed here:
