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
deviceandaspowerfactorcontroller.
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
customerspecificpurposes.
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 automatic initialization 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
byanadditionalESCape-button.
The usage of a fully graphic support display allows an additional Oscilloscope-Mode where

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. The maximum measuring voltage is 440V+ (L-N)/760V~(L-L).
Thesupplyvoltageis110...230V+/-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;itmustbepossible to switch off the supply voltagebyaseparator.
TheBR7000mustnotbeoperatedwithoutprotectiveearthcontactorconnected!
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
bewiredwith minimum 2.5mm Cu.
Terminals may only be plugged when de-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-phasevoltagedrop.)
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
readyforoperation.
Operating the controller without following to these operating instructions may be harmful
anddangerous!

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
differentoperatingvoltages.
Caution!
Voltages which exceed the allowed voltage range can damage the
device !

The upper part of the display always shows the parameter, the adjustable values are
shown in the lower part. Editable values are generally given in square brackets. Changes
of these values can be done by the buttons é/ ê. By pressing the “ENTER-button” the

As a standard, the values of the 2nd parameter set equal the
values of the normal parameter set. Menu entries 23...36 permit a
systematic change of the 2nd parameter set. Possible applications
are for example: changing of target cos-phi, switch-over of current
transformeror switch-over the switching times.
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

8 CONNECTING TIME: [ 40 ] sec. ( 1 sec. ... 20min.)
This refers to the time between the connections of capacitors to increase the
actualsystemcapacitance
9 DISCONNECTING TIME: [ 40 ] sec. ( 1 sec. ... 20min.)
This refers to the time between disconnecting of capacitors to decrease the
actualsystemcapacitance.
10 DISCHARGE TIME: [ 60 ] sec. (1sec....20min.)
This is the time for which an individual output is locked between its
disconnectingandconnecting.
