Commissioning Instructions Rev. 03
Power Factor regulator BLR-CM
Connection
Only qualified staff is
allowed to perform the
installation. All legal
rules have to be ob-
served 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, fre-
quency 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 plas-
tic 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 Pay special
attention to the cross section size of the CT connections!
An integrated voltage observation with regard to the auxil-
iary voltage in BLR-CM guarantees a safety disconnection
of the capacitors in case of undervoltage It must be en-
sured, that auxiliary voltage is taken from the identical
phase as control voltage for the contactors, 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!

User Interface of BLR-CM is a graphical LCD and a membrane keyboard with 4 softkeys
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
parametered 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
1 Step 1, status: off, type: NORMAL
2! Step 2, status: off, type: NORMAL blocked or FIX OFF
F Step 3, status: off, type: FAULTY
4 Step 4, status: on, type: NORMAL
5! 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
“PFC OFF” can be caused by voltage out of tolerance, by relay is off due to setting or due to Alarm system
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

Attention: The present manual is for the first commissioning. For further explanations and more possible settings, please
check the reference manual.
For ease of use and adjustment the BLR-CM user interface consists of a combination of graphical LCD display and 4 soft-press-keys
The following flow chart shows step by step how to commission the BLR-CM The steps below should be followed by pressing the high-
lighted soft-press-keys on the BLR-CM

Function of the setting of nominal voltage is to make a definition about the nominal
voltage of the system The threshold levels for under- and overvoltage are based on this
as well as the ratings of the capacitor sizes in step database, which are used for control
and monitoring The capacitor sizes, which are stored in step database, are also r
ated to
the nominal voltage
Independent of connection of the voltage measuring channel, nominal voltage is
always the phase-phase voltage!

VT FACTOR is the ratio of the voltage transformer If the regulator is connected directly
to the measurement voltage without VT the value 1 has to be used
Automatic initialization is switching all exits During this test it can get information,
which exits are working and it can correct the connection of the measuring channels for
voltage and current by internal settings
Automatic initialization can be started only when the “happy face” is shown (voltage
and current are ok) and when CONTROL is not set to status OFF or FREEZE manually or by alarm-system If
CONTROL setting is FREEZE done by AI, then a restart is possible
When AI is running, the status line of BLR-CM shows the message: “AI ACTIVE” The maximum number of
switching operations during AI is 10 per exit (normally between 2 and 5) AI is taking care about the setting of
discharge time for each exit If there is a very long discharge time necessary, AI will take a certain time
The following messages from AI are possible:
ALARM: AI OK
AI is finished completely Please check if all used exits are shown with their number in the display and please
check if BLR-CM is working correctly
ALARM: STEPS (CONTROL setting is: FREEZE)
Capacitors cannot be detected, because they are not controlled by controller or the rating is smaller as limit
AI ABORTE (CONTROL setting is: FREEZE)
AI couldn’t be finished The reason could be permanent load variation during AI Please try it again or do the
settings manually

The switch interval is the time delay between switching steps in regulation
The switch interval has two different functions:
1 Protecting the contactors by reducing the number of switching cycles
2.

FIX-ON = step is permanently switched-in
(step will be switched-off in critical situations like over- and
under voltage, over temperature or excessive harmonics)

ISCHARGE TIME:
Allows to set the discharge time for each step individually
After completing the steps above, the controller will check the measured voltage and current If all measured values are within the pre-
scribed tolerances, the controller start will start normal operation
If the controller remains in this setup status for more than 5 sec use the flowchart above to check the VT ratio the
nominal voltage and the connection of the voltage measurement
If the controller remains in this setup status, check the connection of the current transformer e g has the short
link been removed and is the respective CT ratio correctly set?
As soon the controller has acquired the measurement voltage and the measurement current it shows the current
cos phi and starts with normal operation

To enter in manual mode, please select “MANUAL” and push ► for 3 seconds The automatic control is frozen
and the exits can be switched manually By the means of the + -key the referring step can be selected Chang-
ing the switching state is possible by pushing the ◄►-key
Manual switching is only possible when measurement voltage is in allowed range. Otherwise
over- and undervoltage protection will block this function. After switching off an active step the
discharging time is active. Only after this time is over the step can be switched on manually
again.
