Section 1: GENERAL

The power factor controller BR7000 is the consequent follow-up development of the well
proven series BR6000.
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
device and as power factor controller.
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
customer specific 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
conventional three-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
by an additional ESCape-button.
The usage of a fully graphic support display allows an additional Oscilloscope-Mode where
the phases (half waves) of voltage and current can graphically be 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. The maximum measuring voltage is 440V+ (L-N) / 760V ~ (L-L).
The supply voltage is 110...230 V +/-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; it must be possible to switch off the supply voltage by a separator.
The BR7000 must not be operated without protective earth contactor connected!

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

be wired with minimum 2.5 mm 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-phase voltage 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
ready for operation.

Operating the controller without following to these operating instructions may be harmful
and dangerous!

BR 7000 front view

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
different operating voltages.

Caution!

Voltages which exceed the allowed voltage range can damage the

Section 3: CONNECTION ALTERNATIVES MEASURING VOLTAGE

AND MEASURING CURRENT

According to the existing grid and the desired operating mode (CONTROL-MODE
Programming) the BR7000 has to be connected accord. one of the following alternatives.

In grids without neutral conductor the connector N(PE) from meas.voltage at
the controller has to be connect with the PE of the grid !

Alternative 1: measuring performed in each phase - 3 current transformers needed
Use: CONTROL-MODE: 1 - 4 (control modes see page 11)

BR7000

Alternative 2: single-phase measuring via current transformer in L1 Values extrapolated (balance assumed).

Measuring complies with conventional measuring for switching of three-phase capacitors.
Use: CONTROL-MODE 5

BR7000

Alternative 3: single-phase measuring as alternative 2 , but with capacitor current measuring in the compensation

system for collection of real capacitor currents.
Use: CONTROL-MODE 6

Sum-current converter: 5A+5A / 5A

C.converter ratio is: 2000 /5A

Connection of current transformer / sum current transformer

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 is connected
up via sum-current converters, the overall conversion ratio is entered.
Current converter clamps should be grounded on one side!

Caution!
Current converter clamps should
be grounded on one side !

The secondary clamps of the CT
have to be short circuited before
current leads are iterrupted !

Section 4: DISPLAY - FUNCTIONS

After the operating voltage has been switched on, the BR7000 briefly indicates with
description and software-version before changing to automatic operation.

Actual values and symbols of the particular operation state are shown in the display.
In the automatic operation (standard) capacitor steps are automatically switched on or
off to reach the pre-set target cos-phi. This happens when the required reactive power is
higher than the value of the smallest capacitor step.

Control direction is symbolized by a
compact arrow:

Connecting-out

The connecting-in arrow is always
located after the maximum possible
number of stages (end stop)

An open arrow indicates that the
required blocking time (Discharge time)
is running before an impending
switching step

=== PROGRAMM-MODE ===

3 I-CONVERTER PRIM [1000 ] A / X ( 5 ... 13000) A

Selects the primary current of the current converter.
Sequential adjustment of L1...L3.
via the é / ê keys. Save and continue with ENTER

4 I-CONVERTER SEC 1000 A /[ 5 ]A ( 1 / 5 A )

This sets the secondary current of the current converter.
Selection via é / ê. Save and continue with ENTER

5 END STOPP

Programming of the maximum number of active
capacitor branches.
Depending on the selected operation mode the
maximum number of connected capacitors at the output
groups L1…L3 and (if available) for the output groups Σ
(three-phase capacitors) are set.
The visible symbols of the capacitors correspond to the
connected outputs.
Input via é / ê. Save and continue with ENTER

6 CONTROL SERIES [1] ( 1...20 + ED )

The ratio of the capacitor branch powers determines the
control series, the power of the first capacitor always
being assigned the value 1.

Selection of desired control series consecutively for

L1…L3 and for Σ (three-phase outputs).

If the required control series should not be present, the

user may define a special one in control series “ED” ( see
Annex 4: Control-series editor )

7 CONTROL PRINCIPLE
The control preference may be selected here:

SEQUENTIAL connection
LOOP connection
INTELLIGENT loop connection (default setting)
COMBINED CHOKE

See Section 13 for an explanation of the control modes.
Selection with é / ê keys.
Save and continue with ENTER

8 POWER 1st STAGE [0.01 ... 255.99] / [10...2550] kvar

To determine the controller's response sensitivity, the
dimensions of the 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 capacitor value is below the response sensitivity, a
warning will occur ( indication of “!” in the display )
