P.F.C. ELECTRONIC REGULATOR BMR series Installation and Operating Instructions Please read this handbook careful: it provides important information about safety, usage and The BMR electronic regulator allows the control of the power factor (coscp) 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 removing A large LCD display allows read. Regulator operation is the front panel. All the user operations can be performed using the four button keypad. 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 LI 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 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. tensione / voltage aliment, regolatore power supply corrente / current sonda temper. temp, probe The parameters can be set by two menus: a base menu ("PAR SETUP") and advanced ("MAINSETUP"). To navigate between the setting paramaters press the SETUP button; press Q DOWN or Q UP button to modify each paramater. In the first menu ("PAR SETUP") the parameters to set are the minimum installation required and are shown below: -^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 cos9 regulation. OVER TEMP => maximum operating temperature (°C). THERM THD 1% => THD(I)% alarm value (see also the OVER THD 1% => instantaneous THD(I)% peak alarm SENS THD 1% => 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 1% value; To modify these parameters, press and hold the SETUP button and change using the UP or DOWN

(1): To switch between AUTOMATIC and MANUAL mode, press the MAN/AUT button for 5 sees. To switch ON or OFF a bank manually, press MAN/AUT for 5 sees, (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. In the menu advanced ("MAIN SETUP") you configure the compensation equipment parameters like: kvar power banks, capacitors rating voltage, switching delay, network rating frequency, type of network (single or 3-phase), alarm...
