Control Mode:
1) Kvar Mode :
Ÿ
When this mode is selected, capacitor bank switching step is not fixed and the program automatically selct the most appropriate steps to switch capacitor bank “ON’ or “OFF” in order to achieve target PF by shortest reaction time with minimum number of steps. kvar
Press key
Enter Password
As Per set in configuration 2) Intel Mode :
Ÿ When this mode is selected the capacitor steps are controlled by increment of lowest KVAr value of capacitor bank to higher KVAr value of capacitor bank combinations using binary steps to achieve required KVAr value and target PF.

3) MANUAL Mode :
Ÿ When this mode is selected the capacitor steps are controlled manually by the
UP ( ) and DOWN ( ) KEY.
Capacitor Bank Sensing :
1) MANUAL :
Ÿ If customer select manual Capacitor Bank Sensing method then it will be mandatory to enter capacitor bank KVAr value for each step.
Ÿ No need for external CT.
2) CAPACITOR CT :
Ÿ If customer select Capacitor CT Capacitor Bank Sensing method than capacitor bank automatically sense by capacitor CT.
Ÿ The use of capacitor CT is mandatory.

Other Setting :
1) SCAN TIME :
Ÿ This parameter set the switching speed of capacitor bank. A larger sensitivity time will result in slower switchingspeed. (Range : 0 to 999.9 sec)
Ÿ This sensitivity applies to both switching “ON” and switching “OFF” of the capacitor
2) PROGRAMMABLE Kvar HYSTERESIS :
Ÿ The programmable Kvar hysteresis applicable on required KVAr value to achieve target PF. (Range : 0 to 25 KVAr)
Ÿ This setting applies to both inductive & capacitive KVAr Requirement
Four Quadrant Representation
Ÿ As Per IEC 387 IF Reactive Power is Positive (+Ve) than it is consider as a
Inductive Load if Reactive Power is Negative (-Ve) then it is consider as
Capacitive load.

In Quadrant 1 a positive reactive power indicate an inductive power factor.
In Quadrant 2 a negative reactive power indicate an capacitive power factor.
In Quadrant 3 a negative reactive power indicate an capacitive power factor.
In Quadrant 4 a positive reactive power indicate an inductive power factor.

3) Minimum Operating Current :
Ÿ If customer select the value of operating current, than in case of secondary CT Current Less then selected value.
Ÿ Then APFC Relay will stop controlling (Range : 10 to 500mA)

4) Target PF:
Ÿ This set the targeted power factor required when the system is under automatic mode. The power factor regulator will switch the capacitors in or out in order to achieve this set value.

Mechanical Installation Guideline
1) Prepare the panel cutout with proper dimensions as shown above.
2) Fit the unit into the panel with the help of clamp given.
3) The equipment in its installed state must not come in close proximity to any heating
!
source, caustic vapors, oil steam, or other unwanted process byproducts.
4) Use the specified size of crimp terminal (M3.5 screws) to wire the terminal block.
Tightening the screws on the terminal block using the tightening torque of the range of
1.2 N.m.
5) Do not connect anything to unused terminals.
Safety Precaution
Please read the "Safety Warnings" in the instruction manual supplied with
the instrument thoroughly and completely for correct use. Failure to follow the safety rules can cause fire, trouble, electrical shock, etc. Therefore, make sure to operate the instrument on a correct power supply and voltage rating marked on each instrument .
If all the equipment is not handled in a manner specified by the manufacturer, it might impair the protection provided by the equipment.
Read complete instructions prior to installation and operation of the unit.
WARNING : Risk of electric shock.
Installation Guidelines
1) Do not allow pieces of metal, wire clippings, or fine metallic fillings from installation
to enter the product or else it may lead to a safety hazard that may in turn endanger
life or cause electrical shock to the operator.
2) Circuit breaker or mains switch must be installed between power source and supply
terminal to facilitate power ‘ON’ or ‘OFF’ function. However this mains switch or
circuit breaker must be installed at convenient place normally accessible to the
operator.
3) Use and store the instrument within the specified ambient temperature and
humidity ranges as mentioned in this manual.
Maintenance
1) The equipment should be cleaned regularly to avoid blockage of ventilating
parts.
2) Clean the equipment with a clean soft cloth. Do not use isopropyl alcohol or
any other cleaning agent.
3) Fusible resistor must not be replaced by operator.
Warning Guidelines
WARNING : Risk of electric shock.
1) To prevent the risk of electric shock, power supply to the equipment must be kept
OFF while doing the wiring arrangement. Do not touch the terminals while power is
being supplied.
2) To reduce electro magnetic interference, use wire with adequate rating and twists
of the same of equal size shall be made with shortest connection.
3) Cable used for connection to power source, must have a cross section of 1mm or
greater. These wires should have insulations capacity made of at least 1.5kV.
4) A better anti-noise effect can be expected by using standard power supply cable for
the instrument.
