OVERVIEW
Please read this handbook careful: it provides
important information about safety, usage and
maintenance of our product.
The BMR electronic regulator allows the control of the
power factor (cosφ) on electric networks by measuring
all the electrical values such as Voltage, Current,
THDI(%),etc...
Using accurate diagnosis software, the regulator
four button keypad.
INSTALLATION
Mounting the regulator in a cut-out panel (138x138mm) by behind
panel clamps.
The regulator is only suitable for an electrical network with a
frequency of 50/60Hz through a Current Transformer placed on the
phase L1 and connected between the K-L terminals.
The C.T. must measure all the currents (inductive and capacitive) to
ensure correct operation.
Voltage references must be connected to lines <L2>-<L3> and the
regulator power supply on terminals <S1>-<S2>;
for voltage supplies provide a fused supply in accordance with your
technical standards. Connect the aux voltage to terminal <C>, which
is common to the NO relay outputs, and connect the outputs 1 to 12
to control the banks of capacitors.
A volt-free contact on leads <C1>-<C2> is available to remote
monitoring an alarm status or to control a cooling/fan system: for fan
control, connect the included temperature probe on <P1>-<P2>
leads.
Be sure to know the harmonics characteristic of the network
that must be compensated, then ensure the P.F.C. equipment
or capacitors you are using are suitable for the network
characteristics and, if necessary to avoid any safety problem
on your equipment, adjust the THERM THDI% and OVER
THDI% parameters.
PROGRAMMING
The parameters can be set by two menus: a base menu ("PAR
SETUP") and advanced

Installation and Operating Instructions
PAR SETUP programming parameters description:
PAR CT =>
SENS =>
OVER TEMP => maximum operating temperature (°C).
THERM THD I% => THD(I)% alarm value (see also the SENS THD
OVER THD I% => instantaneous THD(I)% peak alarm value.
SENS THD I% =>
SENS DOWN => alarm reset time delay: if set to ON, resume
instantaneously the normal operations when the alarm ends;
if set to OFF, resume the normal operations with a delay
time equals to the SENS THD I% value;
To modify these parameters, press and hold the SETUP
button and change using the UP or DOWN buttons.
(1): To switch between AUTOMATIC and MANUAL mode, press the
MAN/AUT button for 5 secs.
To switch ON or OFF a bank manually, press MAN/AUT for 5 secs.
(the AUT led turns off and the MAN led lights), press UP or DOWN
to select the capacitors bank desired then confirm with SETUP
button. To verify the status of the bank selected, the power (in kvar)
appears on the display.

The setup of the THERM THD I% parameter is connected at the
technical characteristics of the installed capacitors.
Please, check the technical details supplied by the manufacturer for
the maximum harmonic current level for witch the capacitors are
designed.(Ex. 50% for 60 seconds).
The internal program of the regulator records the level of current
harmonic distortion in the point where is installed the C.T.
SETUP
If the instantaneous THD is higher then the programmed THERM
level, the instrument abates the SENS value with step 1 second. Up
to reach 0, where all the steps will be disconnected steps by steps.
The re-insertion of steps will be possible only when the THD
measured is less than the programmed THERM level.
