1. Installation
1.1 Physical
The instrument is built in a plastic box to be installed in a distribution board panel. The instrument’s position must be fixed with locks. Put the locks into square inserts placed
diagonally on the top and bottom of the box and tighten the screws to the panel.
Natural air circulation should be provided inside the distribution board cabinet, and in the instrument’s neighbourhood, especially underneath the instrument, no other
instrumentation that is source of heat should be installed.
1.2 Instrument Connection
1.2.1 Power Su ly and Measuring Voltage
1.2.1.1 NOVAR 2100
It is necessary to connect an auxiliary supply voltage in the range as declared in technical specifications table to the terminals L1 (No. 1) and N/L2 (No.2). The instrument
uses this power supply voltage as measuring voltage simultaneously.
The supply voltage must be connected via a disconnecting device (switch - see installation diagram). It must be situated directly at the instrument and must be easily
accessible by the operator. The disconnecting device must be labelled as the disconnecting device of the equipment. A two-pole circuit breaker with the C-type tripping
characteristics rated at 1A may be used for this; however its function and position must be clearly marked (symbols „O" and „I" according to EN 61010 – 1).
A connection cable maximum cross section area is 2.5 mm2.
1.2.1.2 NOVAR 2200
Connect an auxiliary supply voltage in the range as declared in technical specifications table to the terminals AV1 (No. 1) and AV2 ( No.2).
In case of DC supply voltage the polarity of connection is generally free, but for maximum electromagnetic compatibility it is recommended to connect grounded pole to the
terminal AV2.
The supply voltage must be connected via a disconnecting device ( switch - see installation diagram ). It must be situated directly at the instrument and must be easily
accessible by the operator. The disconnecting device must be labelled as the disconnecting device of the equipment. A two-pole circuit breaker with the C-type tripping
characteristics rated at 1A may be used for the disconnecting device; however its function and position must be clearly marked (symbols „O" and „I" according to EN 61010 –
1). If one of the supply signals is neutral wire N (or PEN) usually a single breaker in the line branch is sufficient.
Measuring voltage must be connected to the terminals L1 (No. 5) and N/L2 ( No.6). Connecting wires should be protected by, for example, fuses of rating 1A.
A connection cable maximum cross section area is 2.5 mm2.
1.2.2 Measuring Current
The instruments are designed for indirect current measurement via external CT only. Signal of any phase and of any polarity can be used.
The current signal from 5A or 1A (or 0.1A for the „X/100mA“ models) instrument current transformer must be connected to the terminals pairs IS1 and IS2 (No. 3 and 4).
The CT-ratio must be set in the Installation group of parameters (par. 71).
A connection cable maximum cross section area is 2.5 mm2.
1.2.3 Relay Out uts
Instruments can have up to 24 relay outputs arranged in up to three groups. The groups are isolated from each other. Each group has one relay common pole terminal C1,
C2 , C3 (No.10, 20 and 30) and six or nine relay output terminals marked – for example for group 1 - 1.1 through 1.9 (No.11 ÷ 19).
Any combination of compensation capacitors and chokes can be connected to the instrument outputs via appropriate contactors.
If not of all outputs used, you can use upper three relay outputs for alarm signalling or for heating/cooling control.
A connection cable maximum cross section area is 2.5 mm2.
1.2.4 Digital In ut
Models with 18 and 24 outputs are equipped with the digital input. It can be used for the 2nd tariff control of power factor control process or as the alarm input..
Use terminals D1A and D1B (No. 51 and 52) for the digital input connection – see wiring examples in appropriate chapter further below. The input is isolated from other
instrument circuitry.
To activate the output apply voltage of specified range to the terminals.

2. Commissioning
On connecting power supply, the instrument performs internal diagnostics, display test and then gradually shows screens with the instrument type and setting of basic
parameters : instrument model and firmware version number, VT-ratio (if indirect voltage connection is set), CT-ratio and nominal frequency fNOM and nominale voltage UNOM.
Then the instrument starts display actual measured values. Simultaneously, if the instrument has a communication line, it can be set and its measured values read via the
communication link using a PC.
As, because of the first installation, the instrument knows neither output types nor reactive power sizes of individual outputs, it gets into the standby mode, which is signalled
by flashing symbol .
If measuring voltage is present and measured current reaches at least minimum level, the instrument tries to start automatic connection detection (ACD) process that is
indicated with flashing symbol and the A C d message. As soon as it occurs, switch into instrument parameters with the key. When parameters are displayed, the
ACD-proces is cancelled and the controller stays in the standby mode until it returns back to measured quantities display – that occurs automatically after about 30 seconds if
no key is pressed.
At this moment, before we let the ACD-process running it is necessary to set so called Installation parameters, that are essential for proper operation of the instrument.
2.1 Measured Electrical Quantities Installation Setu
For proper data evaluation it is necessary to set the Installation Setting group parameters, starting from parameter 71 up :
•CT- ratio ( p. 71 ). Can be set in form either …/ 5A or …/ 1A.
Furthermore, so called I-Multi lier can be set too. You can modify the CT- ratio with this parameter. For example, to get better precision when using
overweighted CTs, you can apply more windings of measured wire through the transformer. Then you must set the multiplier. For example, for 2 windings
applied, set the multiplier to 1/2 = 0.5 .
For standard connection with 1 winding, the multiplier must be set to 1.
•Connection Ty e ( p. 72 ) needs to be set to 1 Y 3 or 1 d 3. The U1-voltage angle is recommended to be set automatically during so called ACD-
process (see below).
•Connection Mode ( parameter 74 ) determines if voltage signals are connected directly ( - - - ) or via voltage transformers. In such case the VT-ratio
must be set. The VT-ratio must be set in form Nominal primary voltage / Nominal secondary voltage. For very high primary voltages the U-Multi lier must be
used.
•Nominal frequency fNOM ( p. 75 ) must be set in compliance with the measurement network nominal frequency to either 50 or 60 Hz.
•Nominal Voltage UNOM ( p. 75 ) and Nominal Power PNOM ( p. 76 ) : For the voltage alarms operation and other functions it is necessary to enter also the
nominal ( primary ) voltage of the measured mains UNOM and nominal apparent three-phase power (input power) of the connected load PNOM ( in units of kVA ).
Although the correct setup of the UNOM and PNOM has no effect on measuring operation of the instrument, it is strongly recommended to set at least the UNOM
correctly.
The UNOM is displayed either as line-to-neutral or line-to-line form depending on the connection mode setup : “direct” or “via VT”, respectively.
Correct setting of the PNOM is not critical, it influences percentage representation of powers and currents and statistical processing of measuring in the
software only. If the PNOM of measured network node is not defined, we recommend to set its value, for example, to the nominal power of source transformer
or to the maximum supposed power estimated according current transformers ratio, etc.
2.1.1 Setu Exam le
Usually, it is only necessary to adjust the CT ratio. Next example shows how to do it :
Assuming that the ratio of used CTs is 750/1 A. First off all, it is necessary to switch display from measured data branch (the ULN screen on the example below) to the
parameter branch with the button. The branch is indicated with the symbol . Parameter 01 appears – target power factor & control bandwidth.
Now scroll down with the key to parameter 71, that is the CT ratio -its default value is 5/5 A. Enter editing mode by pressing and holding the until the value gets
flashing.
As soon as the value flashes, release the . Now you can change it. Increase primary value by pressing of the . If you keep it pressed two-speed autorepeat helps to
reach target value quickly. Then use multiple pressing of and for fine setup.
To change the secondary value, simply press the . The button serves as toggle switch between 5 and 1.
Target CT value is prepared now and we can leave the edit mode with (short) pressing the . The value is stored into the instrument memory and the flashing stops.

CT Ratio Change Procedure Example
Now return to so called main parameter branch (see description below) with next pressing the and then you can scroll to other parameters with and and edit
them in a similar way or you can return to the measured data branch with the .
The summary of all instrument parameters is stated in the table below. Their description is stated in the full-scale manual.
2.1.2 Connection Setu
The controllers are delivered with preset connection type to 1Y3 and the U1-voltage angle is undefined.
2.1.2.1 Connection Ty e 1Y3 / 1D3
If network hase-to-line voltage is connected to the L1 and N/L2 terminals, the 1Y3 connection type must be set in the parameter group No. 72.
If network hase-to- hase voltage is connected to the L1 and N/L2 the 1D3 must be set.
The above does not have to apply if the measured current signal is taken from the opposite side of the mains power transformer than the measured voltage signal
Then correct setup of the parameter group No 72 depends on the transformer phase angle
Connection type parameter must be set correctly even if use of the automatic connection detection process (ACD) is supposed Otherwise result of the process
would fail and measured powers and power factor would be false !
2.1.2.2 Angle of Voltage Connected to the U1 In ut (U1-Angle )
Generally, it is not necessary to connect voltage and current of the same phase; for example, you can connect the L1-phase current and the L2- or the L3-phase voltage,
even with opposite polarity.
If a line-to-line voltage is connected, or line-to-neutral voltage of different phase than the current, or the voltage and current signal with opposite polarity, there exists phase
shift between the voltage and the current signals even at power factor equal to 1. Controller must respect this angular displacement, so it must be specified correctly,
otherwise it would evaluate wrong power factor.
The value of the angular displacement is defined as a combination of measurement network phases connected to the L1 and N/L2 controller terminals. It is assumed that the
CT is mounted in the L1 phase of measured network and its orientation (terminals S1, S2) corresponds to real orientation supply ->load . The angle of voltage is then
assigned one of six combinations shown in the table below.

Notes :
CT supposed in the L1 phase with correct orientation (S1, S2 terminals)
the U1-angle expressed as „x-y“ where the „x“ means the phase connected to the U1 terminal and the „y“ phase connected to the N terminal (=0)
If the current signal is from opposite side of the power supply transformer than the voltage signal, the U1-angle must be set with respect to the transformer phase
angle
At this phase it is strongly recommended to set the CT ratio in parameter No 71 too It is necessary for successful result of the AOR process that usually follows
immediately after the ACD-process
2.1.2.3 ACD Process – Automatic Connection Detection
The U1-angle can be set manually too, but we strongly recommend to use automatic setup – the ACD process (Automatic Connection Detection). This process not only
detects and sets the U1-angle, but network nominal votage UNOM as well.
For the ACD process usage following condition must be fulfilled : capacitors are connected to the first four control outputs If any chokes connected to the
outputs, the process gets fail results !
Following conditions must be fulfilled for the ACD process launch :
•U1-angle is not defined (---)
•branch of measured data is displayed
Then the controller launches this process automatically after powerup (if it is not in the standby state due to any of alarms).
The process can be restarted manually too. For this, scroll to the U1-angle (P.72) and set it as undefined (---).
First of all, the first four control outputs are disconnected, step by step. Then the instrument waits until discharge time of the outputs just disconnected expires.
After all of the outputs discharged, the instrument starts to switch the four outputs step by step. After each of
the step is switched off, detected U1-angle value is displayed (0-L3 on our example).
When 1Y3 connection type is set the controller supposes a line-to-neutral voltage (L-N) is connected; when
1D3 connection type a line-to-line voltage (L-L) is expected.
If unsuccessful step occurs usually dashes appear. Such steps are not unusual especially when reactive
power in measured network fluctuates strongly.
There may be cases where the angle measured with a permissible tolerance does not match any of expected options. Then estimated angle with decimal points appear (right
screen).
If unsuccessful steps (with the decimal points) of the same results and the question mark repeat frequently, the most likely cause is incorrectly set connection type
Check it and try to start the process again
Ongoing ACD process can be cancelled at any point with the key. Similarly, any alarm activation cancels the process too. In such case, the recognized data are
neglected and neither U1-angle nor UNOM setting is updated.

U1 input voltage type

The process can have up to 12 rounds with four steps each. After each step, the measurement results are analyzed. If the results are
sufficiently stable, the process is finished and the results are displayed.
The End is shown in the process headline and found U1-angle is displayed in the 3rd line (0-L3 in our case).
Furthermore, estimated network nominal voltage UNOM appears in the 2nd line (230V).
On successful completion of the total process, the controller saves recognized U1-angle and nominal voltage UNOM into its memory. Then it returns into the state from which it
was initiated. If it is the control state the AOR process follows usually. Before this, we recommend to check stored values of the U1-angle and the nominal voltage UNOM in the
Installation group of parameters and to correct them optionally.
Otherwise, if the ACD process unsuccessful (the U1-angle not detected) or canceled prematurely no parameters are updated and the process is automatically relaunched
each approximately 15 minutes again in the control mode.
If the first sections have very low powers the ACD process can fail especially while high load at the network Then start the process again (by resetting the U1-
angle to ---) or, if necessary, set it and the UNOM manually
2.2 PFC Setu
As soon as the Installation parameters are set you need to set other parameters that serve for power factor control operation. The parameters can be divided into following
subgroups :
•PFC control setup
•PFC output setup
•PFC alarm setup
As, because of the first installation, the instrument knows neither output types nor reactive power sizes of individual outputs, it gets into the standby mode, which is signalled
by flashing symbol .
So powers of individual outputs must be set now. Other parameters can be modified later.
2.2.1 PFC Out ut Setu
The PFC output setup is determined by parameters 20 ÷ 36.
For the first commissioning, check and - if required - modify the discharge time for set 1 ( parameter 34 ). It is necessary especially at high voltage compensation systems
where discharge time in range of minutes must be set.
Optionally, you can set any of the highest three of outputs as alarm, fan control or heater control.
Now you can finally set output types and sizes. The most comfortable way to do this is by using Automatic Output Recognition (AOR) process.
2.2.1.1 AOR Process
Scroll to parameter 20 and edit its value to R u n. After return to measured quantities display - either manually with the key or automatically after about 30 seconds
without any key manipulation – the AOR process is started.
If load is low or disconnected at all, the default undercurrent ( I< ) alarm ( No 04, parameter 43 ) actuation forces the controller into the standby state In such case
the AOR process cannot be started Therefore, it is necessary to switch this alarm actuation temporarily off ( and to return it back after the AOR-process passes)
After being started, the AOR screen appears : the A O r message in the first line and the symbol flash.
First of all, all of control outputs (i.e. excluding the fixed ones and optional alarm/fan/heating ones ) are disconnected, step by step.
Then the instrument waits until discharge time of the outputs just disconnected expires - such not-discharged outputs are identified with flashing output symbol. That means
that the instrument waits till the outputs are ready to use.
After all of the outputs discharged, the instrument starts to switch the outputs step by step. The number of a step is displayed in the second line and appropriate output is
switched on for a short time. After the step is switched off, its type and size is displayed :
•three-phase reactive power of 7.38 kvar, capacitive, in the third line
•in the second line (behind the output number) type of the capacitor – three-phase type (C123) because of all of three bars displayed behind the step number

AOR-Process Step 1 1 Recognition Example
If a step power was detected as zero, either the output is not used (nothing connected to it) or the step power is too small to be recognized automatically.
After the process passes, new recognized output data are stored into the instrument's memory.
Then, in case that :
•at least one valid output ( capacitor or choke ) was found
•the instrument is not switched into the manual mode
•no alarm action is active
•voltage and current higher than measurable minimums
the instrument starts to control power factor to preset value.
If the undercurrent ( I< ) alarm ( No 04, parameter 43 ) was disabled for the AOR-process to be able to pass without any load in the network do not forget to
reenable it back !!!
Detailed AOR process explanation and all of the instrument functions' description can be found at the full-scale operating manual.
2.2.2 PFC Control & PFC Alarms Setu
Finally, the PFC control parameters (1 ÷ 19) and the PFC alarms parameters (40 ÷ 56) can be modified, if necessary.
Detailed description of all of the parameters can be found in the full-scale operating manual.
2.3 Parameter Checking & Editing
To check or edit the parameters, press the key. As default, parameter group 01 is displayed and symbol (wrench) indicates, that setup data are displayed now.
The parameters are arranged in groups, numbered from 00 up. The number of group is displayed in the first line in format - P. n n (with
preceding dash). You can browse through the parameter groups with the or keys.
If one parameter only in the group, its value is usually in the bottom line as shown at the example (nominal power 400 kVA).
If two parameters in the group, usually the first of them is displayed in the 2nd line and the second in the 3rd line ( nominal frequency 50 Hz
and nominal voltage 230 V).
To edit a particular parameter, scroll to its group. Then press and hold the until the value gets flashing. Now release the key and set
target value with the or , or the key for some of parameters. You can use autorepeat function by keeping one of the arrow keys
pressed too. Finally, press the and the value is stored into the memory.
If more parameters in the group, the first one is chosen when entering editing mode for the first time. If you want to modify the second
parameter only, simply cancel editing of the first parameter without any change and reenter the editing again – now the second parameter is
chosen.
To return back to measured values display, simply press the key. Such return can occur automatically too when no manipulation with the buttons for about 30 seconds.
→→

2.3.1 Side Branch Parameters
The parameter groups are organized by ordinal number in the main branch. The main branch is identified with a dash in the 1st line, preceeding the parameter group number –
for example - P 2 5 .
Some of the parameter groups (No. 25÷28, alarm parameter groups No. 40÷56, etc.) are located on side branches for easier navigation. You can switch to a side branch with
certain parameters by pressing the key and switch back to the main branch in the same way. Unlike the main branch, when the side branch is selected the dash is
displayed in the 2nd line.
For example: in the main branch, while showing parameter group 25 (section powers), you will see :
- P 2 5 - parameter group number with the preceeding dash indicating the main branch
1 . 1 - number of the 1st output section
2 4 . 5 - section 1.1 power : three phase capacitor of 24.5 kvars
Pressing the key you switch to the side branch and the screen changes as follows :
P 2 5 - parameter group number without the dash
-1 . 1 - number of the output with the preceeding dash indicating the side branch
Now you can move up and down in the side branch with with the or keys through all sections’ values.
Pressing the again returns display to the main branch (the dash returns to the 1st line).
You can find overview of all the instrument parameters in tables below.
3. Maintenance, Service
The NOVAR 2100/2200 controllers do not require any maintenance in their operation. For reliable operation it is only necessary to meet the operating conditions specified and
not expose the instrument to violent handling and contact with water or chemicals which could cause mechanical damage.
In the case of failure or a breakdown of the product, you should send it to the supplier for repair. The product must be in proper packaging to prevent damage during transit. A
description of the problem or its symptoms must be delivered together with the product.
If a warranty repair is claimed, the warranty certificate must be sent in. In case of an out-of-warranty repair you have to enclose an order for the repair.
