PC-Software „BR7000-Soft“ (enclosed with delivery)
Windows-Software for programming of the PF-controller BR7000 and for visualization,
storageandanalysis ofgrid parameters.
RConnection to RS485-Bus
RAdministration of several controllers possible
RDirect connection to USB-port of PC via accessory USB-adapter
It allows a comfortable visualization and analysis of grid parameters during online-
operation. At the same time, the storage and graphical analysis of all recorded data incl.
the export- and printing function can be performed. The spectrum of harmonics can
promptlybe displayedas bar chart.
The display and recording mode allows a convenient online-display of different grid
parameters. 3 display arrangements with each up to 12 different parameters can be
shownsimultaneously.All values displayed can be recorded for a later processing.
The step display deliversdetailed informationabout thesingle switchingsteps.
With the configuration manager all parameters of the BR7000 can completely be read
out, edited and stored and can be delivered back to the device. All values can be recorded
ina configurationfile.
The graphic mode allows the graphical display of recorded grid parameters for a
congruent evaluation. All values can be freely configured. Copy and print function are
possible.
A graphic bar diagram in the online-mode allows the display of voltage and current
harmonicsat oneglance.
A detailed description of all software functions can be found in the brochure resp. in the
online-help-functionof thesoftware.

Section 1: GENERAL
The power factor controller BR7000 is the consequent follow-up development of the well
provenseriesBR6000.
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
deviceand aspower factorcontroller.
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
customerspecific 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
conventionalthree-phases-control.
All well proven functions of the BR6000-series are available for the BR7000; for example
the control series editor, the test-run etc. 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
thephases (halfwaves)of voltageandcurrent cangraphicallybe displayed.

Section 2: INSTALLATION AND INSTRUCTIONS FOR USAGE
The BR7000 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 with or without neutral
conductor.Themaximum measuringvoltage is440V~ (L-N) / 760V ~ (L-L).
Thesupply voltageis 110...440V +/-10%.
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 mustbe possibleto switch off the supply voltageby aseparator.
Thedevice mustnot beoperatedwithout protectiveearth contactorconnected!
Before connecting the BR7000, 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
2
bewired with minimum 2.5mm Cu.
Terminals mayonly beplugged whende-energized!
Attention!
During single-phase operation the coil voltage for the capacitor contactors must be drawn
from the same phase as the measuring voltage as only the measuring voltage is
monitored. (Protection against direct re-switching of contactors during a short-term
single-phasevoltage drop.)
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
readyfor operation.
Operating the controller without following to these operating instructions may be harmful
anddangerous!

The controller is supplied for a standard operating voltage of 110...440VAC (+/-10%), 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
differentoperatingvoltages.
Caution!
Voltages which exceed the allowed voltage range can damage the

As a standard, the values of the 2nd parameter set equal the values of the normal
parameter set. Possible applications are for example: changing of target cos-phi, switch-
overof current transformeror switch-overthe switchingtimes.
By triggering a 110...230V~ signal at the external input, the 2nd parameter set is
activated with following values:
The programming of the 2nd parameter set is performed equivalent to the

As a protection against unauthorized changes of the system parameters, the device is
equipped with a programming lock. This can be activated in the EXPERT MODE. When the
lockis active,all parameters canbe checkedbutnot changed.

Section 7: HELP-Functions / actual output assignment
TheBR7000 featuresa contextrelated helpfunction.
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
pagesexplain thegeneralmeaning ofused symbols.
On the help pages 7…9 the actual assignment of the internal relay outputs
K01…K15to thephases andto thecapacitors areshown 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
(MIXEDMODE) andmust beobeyed withoutexeption!

Section 8: ALARM RELAY / ERROR MESSAGES
The contact of the alarm relay (K21) is closed during normal operation and opens in
case of failure. At the same time, the respective error is indicated in plain text in the
display:
UNDERCOMPENSATED - displayand relay
missing reactive power
OVERCOMPENSATED - displayand relay
OVERCURRENT - displayand relay
MEASURING VOLTAGE ??? - displayand relay
OVERTEMPERATURE - displayand relay
OVERVOLTAGE -display andrelay
UNDERVOLTAGE -display andrelay
HARMONICS - display andrelay
Additionally, several messages for different operation states are generated. An individual
adjustmentresp. maskingof singlemessages ispossible inEXPERT-MODE2.
During masking, the display of message, the eventual output via alarm relay and possible
influcenceson thecontrol processare suppressed.
