1 Installation and Connection

Only qualified staff is allowed to perform the installation. All legal rules have to be observed and technical

standards have to be met. Before connecting the device check that all connecting leads are de-energized and

that current transformers are bypassed.

1) Compare auxiliary-, measurement-, control voltage, frequency and the current path of the device (see

type label) with the data of the electricity network.

2) Assemble the relay in the switch panel with the 2 mounting clips. If the device is not fitting in the

cutout the small plastic bars on the side of the case can be removed with a knife.

3) Connect protective ground to the terminal link of the case.

4) Connect in accordance to the wiring diagram (see chapter "connection"). Pay special attention to the

cross section size of the CT connections! An integrated voltage observation with regard to the auxiliary

voltage in BLR-CM guarantees a safety disconnection of the capacitors in case of undervoltage. It must

be ensured, that auxiliary voltage is taken from the identical phase as control voltage for the contac-

tors, to guarantee that all switching elements are safely switched off in case of under voltage.

5) Remove short circuit links of the current transformer before commissioning!

1.1 Auxiliary voltage

At BLR-CM auxiliary voltage has to be connected separately from measuring voltage. The terminals for auxiliary voltage

are marked with La, Lb and 0.

Terminal 0 has to be connected always. La and Lb are different tapping points of the transformer to allow the usage

with different voltage levels. The detailed connection depends on the device type and can be seen on the sticker at the

rear side of the regulator.

1.2 Current measurement

BLR-CM can be used in combination with x/5Amp current transformer as well as with x/1Amp types. The terminals for

CT connection are marked with K (S1) and L (S2). CT has to be mounted in the way, that K (P1) connected to the feeder

from utility and L (P2) is connected to load.

Current measuring is necessary for calculation of control deviation and capacitors sizes for reactive power regulation as

well as for showing and monitoring different measuring values.

BLR-CM can be used with summation transformer as well. To get proper function, please pay attention to correct po-

larity of all CTs and to the correct setting of CT-factor. The CT-factor for a summation transformer can easily be calcu-

lated by adding the single transformer ratios (e. g. 1000A/5A + 1000A/5A + 1000A/5A = 200 + 200 + 200 = CT-factor

600).

At BLR-CM3phase (option -3A) please take care that the current inputs are connected to the correct phases

in clockwise rotary field.

1.3 Voltage measuring

Terminals Um1 and Um2 are used for voltage measuring. Effective range is 50V to 530V AC and 45Hz to 65Hz. Voltage

measuring is necessary for calculation of control deviation and capacitors sizes for reactive power regulation as well as

for monitoring and protecting capacitors against over- and undervoltage and THD U and for showing different measur-

ing values.

If voltage is out of tolerance (range can be set), all active steps are disconnected and the regulation stops.

Voltage has to be measured as standard either from L1-N or L2-L3. If measuring voltage is taken from L1-N or from L2-

L3, is detected automatically by comparing the value of measuring voltage with the setting of nominal voltage.

It’s also possible to measure voltage from other phases as above. In this case either automatic initialization must run

(2.4.5) or the correct setting for phase-compensation (2.5.3.6) has to be done. Details of the functions can be found in

the referring chapters.

1.4 Control outputs

BLR-CM is available with up to 12 outputs. Depending on the regulator type the outputs can be relay outputs, transistor

outputs or a mix between both types. The indication of the type can be found on the rear sticker either with the type

description or the symbols of the output clamps.

If you have got the regulator type with mixed output steps, please pay attention that the clamp A1 is the

common root for the relay outputs 1 - 6 and clamp A2 is the common root for the transistor outputs 7 - 12!

1.4.1 Relay outputs

The relay outputs of the power factor controller are designed for the direct connection to contactors. The relay outputs

are potential-free with one common root.

Maximum breaking capacity for ohmic load: 250V AC / 5A, 400V AC / 2A, 110V DC / 0,4A, 30V DC / 5A.

Maximum fuse rating: 6A.

1.4.2 Transistor outputs

The transistor outputs of the power factor controller are designed for the direct connection to thyristor switches. These

open-collector outputs have got one common root. To trigger a thyristor switch connect (–) to the root and (+) directly

to the thyristor switch.

Maximum breaking capacity: 8-48V DC / 100mA

1.5 Alarm relay

BLR-CM is equipped with an alarm relay to signal proper function of the system. The alarm relay has one C/O contact.

The common point is terminal M.

Between the terminals M and MO is the breaking contact. This contact is closed in alarm condition or when BLR-CM is

disconnected from voltage.

Between the terminals M and MS is the closing contact. This is closed in proper condition of the system.

The breaking capacity is 3A / 250V AC.

The circuit diagram is depicted in chapter 3.9!

1.6 Digital input

1.6.1 Digital input for alarm-system

BLR-CM is equipped with a digital input for AC-voltage for alarm-system (50-250V AC, terminals DI1.1 and DI1.2). Digital

input can be active high or active low. The function can be programmed in the menu "SETUP / ALARM / DI INPUT" (2.5.7)

More details for the programming can be found in chapter "ALARM". See circuit diagram in chapter 3.9!

1.6.2 Digital input for data-logger synchronisation (only option –DM)

BLR-CM with option –DM is equipped with a digital input for DC voltage (10-30VDC, terminals DI0.1 and DI0.2). More

details can be found in chapter 2.5.9. The circuit diagram is depicted in chapter 3.10!

1.7 Digital output

BLR-CM is equipped with one digital output (terminals DO1 and DO2). This output is a potential-free closing contact.

The breaking capacity is 5A / 250V AC. The function of this output can be programmed in the menu "SETUP / ALARM"

(chapter 2.5.7). The circuit diagram is depicted in chapter 3.9!

1.8 User Interface

User Interface of BLR-CM is a graphical LCD and a membrane keyboard with 4 soft keys.

LCD is split into 4 areas:

Top area: the two lines of top area are showing information about general status of the relay. The readings

of this area are always available, independent from the menu which is used. The readings of top

area can be adjusted in menu SETUP/DISPLAY.

The “sad face” indicates that there are problems with the level of voltage or current.

The “happy face” indicates that levels of voltage and current are ok.

The “serious face” indicates setting PFC OFF or PFC FREEZE.

Status columns: left and right column are showing the status of the control exits.

Step 1, status: off, type: NORMAL or FAST

Step 2, status: off, type: NORMAL blocked or FIX OFF

Step 3, status: off, type: FAULTY

Step 4, status: on, type: NORMAL or FAST

Step 5, status: on, type: FIX ON

Step 6, status: off, type: OFF, not available or PFC OFF

“NORMAL blocked” can be caused by discharging time (2.5.4.1)

“PFC OFF” can be caused by voltage out of tolerance (2.5.3.7 and 2.5.3.8), by relay is off due to

setting (2.4.6) or due to Alarm system (2.5.7).

Main area: the three lines of main area are for menu navigation and display of information

Softkey area: the soft key area shows the function of the membrane-keyboard. Depending on the opened

menu, the function is different.

2.2 HARMONICS

The BLR-CM is permanently calculating the harmonics of the voltage and current by using Fourier

transformation. After selecting the submenu these values are displayed separated in even and odd

harmonics of current and voltage in main display area. Every displayed value is related to the fun-

damental wave.

Selection can be done by pushing the ◄►-key.

Scrolling is possible by pushing the ▲/ ▼-keys.

2.3 STEPINFO

Stepinfo shows the information, which is saved in step database. By pushing +-key, the step can be

selected. By pushing ▼-key, the different saved values can be selected. These values are: type of

step, switch cycles, actual capacitor size and derating of capacitor in percent.

2.3.1 STEP TYPE

Different types of steps are possible. With exception of the type FAULTY, the types can be set in SETUP/STEPS (2.5.4.2).

Possible types are:

NORMAL = step is used for normal regulation

FIX-OFF = step is permanently switched-off

OFF = step is permanently switched-off an blend out

FIX-ON = step is permanently switched-in

(step will be switched-off in critical situations like over- and undervoltage, overtemperature or excessive har-

monics)

FAST = step is used for real-time algorithm. More information can be found in chapter 2.5.4.2 and 2.5.5.

FAULTY = the step is detected as defective and is blocked

2.3.1.1 FAULTY STEPS

The detection of faulty steps is only possible, when the automatic step recognition is active (2.5.5.7) and switch cycle is

at least 1 sec. When switch cycle is less 1 sec step recognition is automatic off. A step is “FAULTY”, when BLR-CM cannot

detect any change of reactive power at three switching operations in series of this step.

Faulty steps are signed with "F!" in the status columns. Furthermore the step type "FAULTY" is shown. Defective steps

are blocked for the regulation. Faulty steps can be reset in SETUP/RESET (2.5.10.2), by interruption of supply voltage of

BLR-CM or automatically after 24 hours. Afterwards the step is used again for its regular control function.
