At start of Auto Initialization display shows "Ato"
1. Auto Init enables detection of phase correction angle between voltage and
current , number of capacitor bank and capacitor bank kVAr connected.
Auto option will become "No" automatically once auto initialization is completed
successfully.
2. For successful auto init voltage should be healthy, otherwise Auto Init will be
terminated and display shows "InP" and test is aborted.
3. For detection of phase correction angle the power factor should be in range
of 0.6 Lag to 0.99 Lag. if detected successfully then display shows angle on
screen.
4. Load conditions are stable and No error detected then average of three
attempts of capacitor bank kVAr values is calculated by switching capacitor
bank one after other. and three attempts are made to get capacitor bank kVAr
values.
during capacitor switching the attempt

6. Control Series 6: {1,2,3,6,6,6,6,6}
7. Control Series 7: {1,2,4,4,4,4,4,4} Note: If control series 1 to 9 is
8. Control Series 8: {1,2,4,8,8,8,8,8} selected then device will
9. Control Series 9: {1,1,2,4,8,8,8,8} accept only C01 value.
Default control series Number is 1. if "u" is selected
and default C1 value is 25 kVAR. then all capacitor bank values
Default capacitor bank value for ‘U’ is need to be entered

Pressing the will enter to edit number
of capacitor banks count. The range of
setting is depending on orderd instrument
or previously detected in auto init function.
Maximum value is 8.
Select value using key and for Setting the same
press the key. This screen is not shown if auto mode is selected.
After Setting the Number of banks count ,Press key to move to capacitor
bank kvar Value Setting.
3.8 Capacitor Bank kvar Value Selection:
The Screen displays "CAP". Pressing the
key will enter to edit kvar value of capacitor
bank. The Screen will display "C01" followed
by its kvar value. the range of value is 1 to
to 250. if control series is 1 to 9 then only
C01 screen shown and next capacitor bank
screens not shown. For control series U all
bank screen C01...C0n are shown and value
can be set as per bank count set previously.

The Control Series Selection will act as an Multiplier for the Capacitor Banks.
Selecting the Control Series 1 will select multiplier {1,1,1,1,1,1,1,1} for
Capacitor Bank 1 to 8 depending on number of outputs.
After Setting the Series Press key to move to Number of Banks Selection.

if CtL as "u" the value entered in C01 will be the Capacitor Bank value. The value
entered in CXX will be the value for respective Capacitor Bank.
After setting the values for number of selected banks pressing the will move
forward to manual relay on-off function.
if CtL as bank mode ( 1 - 9 ), the value enetered in C01 will be set as the
multiplicand for Capacitor Banks.
Example: The value set in Control Series is 3 - {1,2,3,3,3,3,3,3} and C01 is
2 kVAR then the Bank values will become C01(Bank1) = 2kVAr x 1 = 2 kVAr,
C02(Bank2) = 2kVAr x 2 = 4 kVAr, C03(Bank3) = 2kVAr x 3 = 6 kVAr and
so on.

4. Installation
Mounting of PFC is featured with easy “Clip- in” mounting. Push the instrument in panel slot
(size 92 x92 mm), it will click fit into panel with the four integral retention clips on two sides
of instrument.
If required Additional support is provided with swivel screws (optional) as shown in figure.

mounting
Swivel screw
As the front of the enclosure conforms to
IP 50. additional protection to the panel may
be obtained by the use of an optional panel
The PFC should be mounted in a
reasonably stable ambient temperature and
where the operating temperature is within
the specification . Vibration should be
gasket. The terminals at the rear of the
product should be protected from liquids.
kept to a minimum and the product should
not be mounted where it will be subjected
to excessive direct sunlight.
Caution
1. In the interest of safety and functionality this product must be installed by a qualified
engineer, abiding by any local regulations.
2. Voltages dangerous to human life are present at some of the terminal connections of
this unit. Ensure that all supplies are de-energised before attempting any connection
disconnection.
3. These products do not have internal fuses therefore external fuses must be used to
ensure safety under fault conditions.

4.1 EMC Installation Requirements
This product has been designed to meet the certification of the EU directives when installed
to a good code of practice for EMC in industrial environments, e.g.
1. Screened output and low signal input leads or have provision for fitting RF suppression
components, such as ferrite absorbers, line filters etc., in the event that RF fields cause
problems.
Note: It is good practice to install sensitive electronic instruments that are performing critical
functions, in EMC enclosures that protect against electrical interference which could cause a
disturbance in function.
2. Avoid routing leads alongside cables and products that are, or could be, a source of
interference.
3.
4.
To protect the product against permanent damage, surge transients must be limited to
2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source.
The unit has been designed to automatically recover in the event of a high level of
transients. In extreme circumstances it may be necessary to temporarily disconnect the
auxiliary supply for a period of greater than 5 seconds to restore correct operation.
ESD precautions must be taken at all times when handling this product.

4.4 Auxiliary Supply
PFC should ideally be powered from a dedicated supply, however it may be powered
from the signal source, provided the source remains within the limits of the chosen auxiliary
voltage.
4.5 Fusing
It is recommended that measuring voltage and capacitor contactor voltage to be taken from
4.6 Earth/Ground Connections
For safety reasons, panels and accesoriess should be grounded in accordance with
4.3 Wiring
Input connections are made directly to screw-type terminals with indirect wire pressure.
Numbering is clearly marked on the connector. Choice of cable should meet local regulations.
2 2
Terminal for inputs will accept up to 4mm (12 AWG) or 2.5mm (12AWG)Standard
Note : 1) It is recommended to use wire with lug for connection with instrument.
2) For disconnecting the device a switch or circuit-breaker shall be included at the
site and shall be within easy reach of the operator. The specification are as below.
For aux. = At least 1.2 times of applied Power supply.
For Measuring Input = At least 1.2 times of applied measuring inputs.
