Section1 General
The power factor controller is a modern control device of innovative
design with a variety of functions.It is designed for a measuring voltage
of 30...550V (L-N) or (L-L) and a auxillary supply voltage of 110 to 550
VAC.
It features a user interface with a menu-driven display in plain text for
maximum ease of operation. Straight forward symbols and alphanumeric
displays combine maximum ease of handling with convenient presentation of
results.
Display of various grid parameters, storage of various values and a test run
option make it easy to analyse errors and monitor the system.
Main features:
1.Autoinitialisation function that detects connected capacitor kvar,
connected number of capacitor banks,input phase correction angle,
input voltage connection VLL or VLN
2.Various capacitor kvar selection option -
Direct value (Individual capacitor kvar),
Control series (programming of capacitor kvar ratio),
Auto detected capacitor kvar
3.4/6/8 switching outputs
4.Complete menu-guided operation and User interface
5.Illuminated graphic display with 2 x 16 characters
6.Four-quadrant operation
7.RTC option with last three fault logs
8.Display of various line parameters (V, I, F, Q, P, S...)
9.Monitoring of the individual capacitor kvar
3

10.Storage of maximum values, minimum values of line-parameter,
switching-operation values as well as of the turn-on times of
individual capacitor
11.Programming of output
Programming of output as Auto,fixed and faulty. This option used
for skipping step from switching for PF correction
12.Manual control
Manual control allows switching of capacitor and contactor
thus used for diagnosis purpose
13.Error detection for various states and interference-message
output Test run of PFC system with error analysis
14.Recall function of recorded values
st
15.True RMS measurement upto 31 harmonics

Section 3 Installation and connection of the controller
The controller is designed to be incorporated into the front panel of a PFC-
cabinet. It requires a panel cutout of 92 x 92. The controller is inserted from
the front and it gets fitted into panel with help of self clicking & if required
swivel screw can be used.The controller should be installed by qualified
technicians and must be operated in accordance with the specified safety
regulations.
Mounting of the controller is featured with easy “Clip- in” mounting. Push the
meter in panel slot, it will click fit into panel with the four integral retention
clips on two sides of meter. If required, additional support is provided with
swivel screws as shown in Fig. 1
Before the controller is connected up, all leads and cables must be checked to
ensure that no current is flowing through them. Care should be taken to
ensure that the measuring voltage and current are in the correct phase
position. The connection should be set up as shown in Fig. 2. The specified
safety regulations must be observed.
The auxilliary supply voltage is 110 to 550 VAC / DC
The measuring voltage may lie in the range from 30-550 VAC and can be
connected as L-N or L-L. after voltage and current connections enter CT
primary and secondary.
Now as per site conditions Phase correction angle,voltage
type,Capacitor bank KVAr ,Number of capacitor banks parameters can
be set OR Auto initialisation can be carried out to detect above parameters.
Auto-initialisation function designed to works in most of practical load
conditions and system networks. Refer Auto initialisation notes for detail.
if any ambiguty found in system values during or after autoinitilisation then
settings for above can be done in basic settings and advanced system
settings.
