Comar Condensatori BMR Serie Instructions D'installation Et D'utilisation page 4

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
measures only the fundamental values by
read. Regulator operation is indicated by the LEDs on the front
panel. All the user operations can be performed using the 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 ("MAIN SETUP").
To navigate between the setting paramaters press the
SETUP button; press DOWN or
modify each paramater .
In the first menu ("PAR SETUP") the parameters to set are
the minimum installation required and are shown below:
PAR TA→SENS→OVER Temperature→THERM THD I%→
→OVER THD I%→SENS THD I→SENS DOWN.
To access the basic ("PAR SETUP") menu:
set the regulator on MANUAL mode by pressing the
MAN/AUT button and disconnect all the banks (1)
press and hold the SETUP button until to read "PAR
SETUP" onto digital display.
PAR SETUP parameters description:
PAR TA => Current Transformer ratio (eg. 1000/5).
SENS => tolerance sensibility to the cos
OVER TEMP =>
maximum operating temperature (°C).
THERM THD I% => THD(I)% alarm value (see also the
SENS THD I% parameter).
OVER THD I% => instantaneous THD(I)% peak alarm
value.
SENS THD I% => THD(I)% alarm value time (sec.).
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.
