Section 2 Installation and connection of the controller
The controller 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. It may
be inserted only by qualified technicians and must be operated in accordance with the
specified safety regulations.
Before the Prophi-6R 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 VAC and can be connected
between L - N ( default ) or between L - L (programming of phase correction needed)
The supply voltage is 110...230 VAC +/- 15% and can be connected between L - N or
L -L (depending of the grid).
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 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 (page 17)

the automatic test-run is performed.
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 controller will switch into 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.
NOTE: If the Prophi-6R has been put into operation successfully by AUTO-INIT with all
values unknown, some values will be shown as “????” and this can not be changed. If a
new programming is required, a reset is needed before: Programming/Basic settings

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:
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.
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.
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”.

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.
Any discrepancies found are evaluated and displayed in plain text. 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.

The deviation from the rated value of the capacitor, for which a fault message is
generated, can be specified here (see point 14)
16 TEST ATTEMPTS [5] ( 1...9)
When at least this number of successive measurements has resulted in a fault in the
capacitor power, a C-fault message is output.
17 OUTPUT 1. STEP [0...255] (0...2550)
The range for entering the stage output can be increased to [0...2550] here, (e.g. for
medium voltage measurement)
18 CONTROL [3] PHASE ( 3 / 1 )
The measuring system of the controller is generally based on single-phase
measurement. For all standard settings (three-phase), the measurement is
converted and all outputs displayed as three-phase values (symmetry in grid
assumed). In the single-phase setting, display and control apply only to the single-
phase value measured (application: single-phase correction in asymmetrical grids)

8.2. Expert mode 2 ( Password: 2244)
The additional 2nd expert mode includes all messages for operation, warning and error
which are displayed by the controller. Here they may be deactivated separately. When
deactivated, the indication of the message in the display as well as possible activation of
the relay or effects on the control behavior are suppressed (detailed list of all messages s.
menu plan last page).
Also, the alarm relay may be programmed here as 7.stage or as message relay.
Switching operations/operation time of the capacitors can be set back separately.
EXPERT MODE 2 ENTER
2 ALARM RELAY (ERROR) (Error / 7. stage / Message relay)
Selection whether the alarm relay should be used for error message or as
additional 7th stage or as message relay for the standard controller.
Activation of particular operation, warning and error messages (s. above)
Example
3 ALARM DELAY TIME [10] min. (1...255min.)
Time after which the alarm relay will respond
4 UNDERVOLTAGE [50] % (20 ...100 %)
meas. voltage below this threshold will switch OFF all
stages at the same time
5 OVERVOLTAGE [115] % (105 ...140 %)
meas. voltage above this threshold will switch OFF
the stages step by step
If measure voltage returns to the permissible range, stages
will stepwise switch ON again.
6 FREQUENCY [40...80 Hz] (50Hz / 60Hz)
Measurement by the controller is done automatically in grids of 40 … 80 Hz.
In grids with extremely poor voltage quality it is recommend to select a fix
frequency (50 or 60 Hz) to avoid measuring errors due to voltage sags.
7 SWITCH. OPERATIONS C 1 RESET [NO] (YES/NO)

C 6 RESET [NO] (YES/NO)
Reset of switching operations of particular capacitors possible,
e.g. after replacement of particular capacitors or contactors
8 OPERATION TIME C 1 RESET [NO] (YES/NO)

Section 9 Control principle
The control response of the Prophi-6R 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 Interface (not applicable)
Section 11 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 12 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.

In automatic operation, individual stages
are not connected or disconnected
In strongly asymmetrically loaded lines,
differences may occur between control
response and power-factor
measurement, as the power factor is
measured in single phase.
No operating voltage
Check / Solution
Check terminals of the measuring voltage and
current (l and k)!
Check phase position
See above
Current in measuring range?
Line interruption?
Wrong current-converter factor?
Current transformer short-circuited?
Check current-converter ratio
Go through measuring current range
Check connection and phase position!
All stages connected - target cos phi not
reached: compensation network sufficiently
dimensioned?
Check connection and phase position!
Capacitive grid, although all stages
disconnected
No measurement voltage!
Cabinet temperature too high: Outputs are
switched off in stages irrespective of power-line
conditions
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.
