1.- VERIFICATION UPON RECEIPT

1.1.- RECEPTION PROTOCOL

• Make sure that the unit has not been damaged during transport. • Check that the unit received matches that described in your order and

that its electrical features are suitable for the main where it is to be connected. See features label on the rear of the door. ( Figure 1)

Figure 1: Features label of the AFQ-4W and AFQ-3W

• Make sure that it is equipped with the following accessories:

- Main switch handle. - 2 keys for locking the door. - Manual.

In the AFQ-4W-25 and AFQ-3W-25 models there are also: - 4 DIN 580-M8 suspension eye bolts (male). - 4 DIN 963, M8x16 screws.

• Check the shipping documentation. The dispatch note number must coincide with the number marked on the outer part of the unit. Unload and transport the unit following the instructions in section 1.2.- TRANSPORT AND HANDLING

Inspect the unit externally and internally before connecting. • Check that all items of the unit on the packing list are present.

If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service.

AFQ-4W, AFQ-3W


1.2.- TRANSPORT AND HANDLING

The transport, loading, unloading and handling of the unit must be carried out with proper precautions and using the proper manual or mechanical tools to prevent damaging the unit.

If the unit is not to be immediately installed, it must be stored at a location with a firm and level floor, and the storage conditions listed in the section must be observed. 3.3.- STORAGE FOR LONG PERIODS In such a case, the unit should be kept in its original protective packaging.

To move the unit a short distance, the unit's floor support profiles facilitate handling with a pallet jack or forklift. (Figure 2)

The centre of gravity of some units may be found at a considerable height. Therefore, when handling with a forklift, it is recommended that the unit be securely fastened and that no abrupt operations are made. The unit should not be lifted more than 20 cm off the ground.

Figure 2: Transport with pallet jack

When unloading and moving the unit, use a forklift with forks long enough to support the entire length of the base. Otherwise, the forks should be long enough to support at least ¾ of said depth. The forks must be flat and supported firmly by the base. The cabinet must be raised by placing the forks underneath the profile that supports the unit. (Figure 3).

AFQ-4W, AFQ-3W


There might be an offset in the centre of gravity from the centre of the cabinet, as a result of the uneven distribution of loads inside the unit. The necessary precautions must be taken to prevent the unit from tipping over during abrupt operations.

Figure 3: Unloading with a forklift

1.3.- STORAGE

The unit should be stored according to the following recommendations:

• Avoid placing it on uneven surfaces. • Do not store it in outdoor areas, humid areas or areas exposed to

splashing water. • Avoid hot spots (maximum ambient temperature: 45 ºC) • Avoid saline and corrosive environments. • Avoid storing the unit in areas where a lot of dust is generated or where

the risk of chemical or other types of contamination is present. • Do not place any weight on top of the unit cabinets.

3. UNIT INSTALLATION

3.1.- PRELIMINARY RECOMMENDATIONS

The unit installation and the maintenance operations must only be carried out by authorised and qualified personnel.

In order to use the unit safely, it is critical that individuals who handle it follow the safety measures set out in the standards of the country where it is being used, use the personal protective equipment necessary, and pay attention to the various warnings indicated in this instruction manual.

Incorrect installation or configuration of the unit could cause serious damage to the unit itself and to other devices of the installation.

The AFQ-4W-50, AFQ-4W-100, AFQ-4W-150, AFQ-4W-200, AFQ-3W-50, AFQ-3W-100, AFQ-3W-150 and AFQ-3W-200 units are not designed to be connected to low voltage domestic overhead public power lines. These units are designed to be connected in industrial environments, technical areas and buildings powered by a dedicated transformer and not powered directly by the low voltage overhead public power line.

Disconnect the main switch before starting any maintenance task on the active filters.

The unit uses DC and AC capacitors. Before starting any maintenance, wait 5 minutes and check that there is no residual voltage stored in the capacitors.

AFQ-4W, AFQ-3W


Make sure the unit is properly earthed before powering up. Any fault in the earth connection might cause a risk of electrocution to the user and damage to the unit itself in the case of lightning or other transients.

Before operating on the current transformers, make sure the secondary is short circuited. Never open a current transformer secondary under load.

Never power or start up the active filter with the front door open or the side or rear covers removed.

Check that there is a neutral in the place where three-phase active filter connections are made with neutral, AFQ-4W. The active filter must be of the correct size for the harmonic currents it has to filter and to comply with the installation's electrical features.

Check the section 3.4.- SIZING THE NOMINAL CURRENT OF THE AFQ-4W and AFQ-3W to define the correct unit size. Failing to observe the recommendations described in this section might cause the active filter to work incorrectly and prevent proper compensation of the installation's current harmonics.

Connect a reactor of at least 3% of the impedance on the input of each of the loads.

Do not weld the housing of the AFQ to the facility's floor, since this can cause irreparable damage to the device. To secure the cabinet to the facility floor, use the holes designed for such purposes, see Figure 12.

AFQ-4W, AFQ-3W


Figure 12 : Holes used to secure the cabinets to the floor.

3.2.- INSTALLATION LOCATION

The unit must be installed in an environment where the temperature outside the cabinet is between 0ºC and 45ºC, with a maximum humidity of 90% (non-condensing). Do not install the unit close to a hot spot and keep it out of direct sunlight. Ventilation spaces must be left on the side and rear to allow for the use of fans. There must also be sufficient space at the front of the cabinet to be able to open the door if necessary (Figure 13): 200 mm on the sides of the cabinet. 200 mm between the top of the cabinet and the ceiling. 800 mm on the front panel of the cabinet.

Figure 13: Active filter spaces for ventilation.

AFQ AFQ

AFQ-4W, AFQ-3W


Install the AFQ-4W or AFQ-3W in a place protected from water, flammable liquids, gases and corrosive substances.

Make sure there are no power factor correction units installed in the same main as the AFQ-4W or AFQ-3W. If there are any compensation units, these must be detuned in order to avoid interference between them and the AFQ.

3.3.- STORAGE FOR LONG PERIODS

If the unit is not installed after receipt, the following recommendations must be observed to keep the unit in a good state: Keep the unit in a dry atmosphere and at a temperature of between 0ºC

and 45ºC. Avoid exposure to direct sunlight. Keep the unit in its original packaging.

If the active filter is stored for a long time disconnected from the main, a process must be applied to restore the internal dielectric layers of the DC bus capacitors. Table 3 shows the recommendations for starting the unit depending on the length of its storage period.

Storage time Process < 1 year No special treatment required.

> 2 years Connect the AFQ to the mains at least one hour before starting up the unit. Power the unit and leave it in STOP mode

Table 3: Start-up process depending on storage time.

AFQ-4W, AFQ-3W


3.4.- SIZING THE NOMINAL CURRENT OF THE AFQ-4W and AFQ-3W The purchased active filter must be sized for the harmonic currents it has to filter. The nominal current of the AFQ-4W or AFQ-3W must be at least 20% higher than the maximum level of harmonics to be filtered. This factor may be higher depending on the installation features. The active filters can suffer from overloading when trying to cancel the harmonic currents in high-impedance, short-circuit mains. The clearest symptom for detecting such cases is that they originally start from a THD(V) (under voltage) of over 3%. It has been seen that the higher the initial THD(V), the greater the chance of filter overload. The reason for this behaviour is that the load does not behave as a current source, but rather the larger the harmonic current absorbed by the filter the more harmonics are produced by the load, which can produce up to more than double what was initially measured. To avoid this phenomenon, it is best to oversize the active filter by multiplying the initial current of harmonics measured in the load by a safety factor (SFh). In other words:

Ifilter (AFQ) = [SFh · Iload · THD(I) ] Where: Ifilter (AFQ): nominal current of the active filter SFh: safety factor > 1.2. Iload: load maximum current THD(I): load current harmonic distortion

Equation 1: Nominal current of the AFQ. To calculate this safety factor you must first know the parameter called short-circuit ratio RSC at the connection point of the PCL converters (not on the installation input). The short-circuit ratio is defined as the ratio between the short-circuit current of a main (ISC) and the nominal current of the set of non-linear converters (INLC) producing the harmonics to be filtered. (Equation 2)

CNL

SCSC I

IR =

Equation 2: Calculating the short-circuit ratio RSC. In a real installation, the short-circuit current (ISC) in the PCL can be assessed by having the voltage at the said point for two different load currents. For example,

full load, IA and 10% load, IB. If VOC is the rated voltage at no-load, the ISC, can be calculated using the formula shown in Figure 14:

Figure 14: Graph for calculating ISC. The safety factor (SFh) can be obtained from the graph in Figure 15:

Figure 15: Approximate graph for calculating the SFh.

AFQ-4W, AFQ-3W


3.5.- CONNECTIONS

All power and current reading cables must enter the electrical cabinet cover at the bottom, guaranteeing the IP and the user protection against the parts of the cabinet with high voltages (Figure 16).

Figure 16: Cable inlet at the bottom of the cabinet.

Carrying out machining outside of the area enabled for this (Figure 16) risks the integrity of the unit and users, and loss of the warranty.

Machining the cable inlet cover outside the cabinet so that machining chips do not affect the operation of the AFQ.

3.5.2. CONNECTION OF THE AFQ-3W MODELS

The AFQ-3W enables the option of installing two or three current transformers. The option of two current transformers is only possible in three-phase mains with no neutral line.

In three-phase mains with neutral, 3 current transformers are needed to ensure the proper operation of the unit.

Figure 23: Main connection points in the AFQ-4W.

3.5.3.2.- AFQ-3W MODELS The AFQ-3W must be fed with three phases without neutral (L1, L2, L3 and Earth).

Use cables of a cross-section suitable for the filter nominal current.

The minimum cable cross-section will depend on the filter range (Table 4).

Table 4: Minimum cross-section of input cables connected to the AFQ-4W.

Make sure that the AFQ is correctly earthed to avoid the risk of electrical discharge.

3.5.4. CURRENT TRANSFORMER CONNECTION

The TI1, TI2 and TI3 current transformers can be located on the load side (downstream from the AFQ) or on the main side (upstream from AFQ). In the active filter, connections S1/L1, S1/L2, S1/L3 S2/L1, S2/L2, S2/L3 have to be made as shown in Figure 24.

Figure 24: Transformer connection points in the AFQ.

Class 0.2S transformers of the CT or TCH series are recommended.

The use of class 0.2, 0.5s or 0.5 transformers will slightly jeopardise the behaviour of the active filter although they always provide acceptable harmonic filtering replies.

The use of transformers with ratios close to the current to be measured is recommended.

AFQ-4W, AFQ-3W


Current transformers TI1, TI2 and TI3 must be correctly connected for the AFQ filters to work properly. If the phases L1, L2 and L3 are switched in the secondary, the filter will not work properly. Check the connections and make sure that: TI1 measures phase 1 and the transformer output cables are connected in posts S1/L1 and S2/ L1 of the filter cabinet. TI2 measures phase 2 and the transformer output cables are connected in posts S1/L2 and S2/ L2 of the filter cabinet. TI3 measures phase 3 and the transformer output cables are connected in posts S1/L3 and S2/ L3 of the filter cabinet.

3.5.5. SELECTION OF THE MAIN VOLTAGE (ONLY FOR AFQ-3W)

The AFQ-3W has a transformer to power the cooling system and switching devices at 230V. Before powering the AFQ-3W, you need to select the main voltage in the terminals situated next to the connection of the current measurement transformers. There are three terminals: 400V, 440V and 480V. Make the connection in the terminal according to the following rules:

- For main voltages below 420V, select terminal 400V. - For main voltages between 420V and 450V, select terminal 440V. - For main voltages between 450V and 480V, select terminal 480V.

AFQ-4W, AFQ-3W


3.6.- PARALLEL CONNECTION OF 2 TO 8 ACTIVE FILTERS You can connect up to 8 active filters by connecting the three phases plus the neutral in parallel. The load current measurement connects in series so that all of the filters are using the same measuring transformers on the load. (Figure 25)

Figure 25: Parallel connection of 2 to 8 filters.

The current transformers must be connected on the load side.

Section 4.3.3. explains how to configure the active filter to work with different active filters in parallel.

All of the active filters connected in parallel must have exactly the same configuration in the WORK MODE and PARAMETERS. Refer to section 4.3.- CONFIGURATION

3.7.- CONNECTING THE FILTER TO THE MAIN Once the connections specified in the above sections have been checked, the main switch of the active filter will be switched on. When the unit is started, the messages “NOT INITIAL CONDITIONS” , “Starting up…” and “Charging dc bus” must appear on the screen ( Figure 26).

Figure 26: AFQ-4W and AFQ-3W start-up messages.

A few seconds later, the message “Set Up transformer ratio” will appear (Figure 27).

Figure 27: Home screen during the start-up of the AFQ-4W and AFQ-3W.

Another message may appear if there is some problem in the filter connections or the power supply. The section APPENDIX A: DISPLAY MESSAGES of this manual describes all the causes of malfunction and their corrective measures.

AFQ-4W, AFQ-3W


3.8.- FILTER START-UP Finally, start-up the AFQ. To consult all of the configuration parameters in detail, see section 4.3.- CONFIGURATION of this manual.

Before starting up the AFQ, carefully follow the steps given in Configuration 3.8.1 and Verification of the unit 3.8.2.

3.8.1- CONFIGURATION

3.8.1.1.- CONFIGURATION OF THE CURRENT TRANSFORMER (CT) Access the parameter configuration screen by pressing CONF and select the PARAMETERS and CTs MEASUREMENT CONFIG. option (Figure 28):

Figure 28: Configuration of the transformer ratio and the number of modules in parallel.

Configure the CTs RATIO parameter with the ratio between the primary and secondary of the load current measurement transformer. The AFQ admits the following transformation ratios: 5/5, 10/5, 15/5, , 25/5, 30/5, 40/5, 50/5, 60/5, 75/5, 100/5, 125/5, 150/5, 200/5, 250/5, 300/5, 400/5, 500/5, 600/5, 700/5, 750/5, 800/5, 1000/5, 1200/5, 1500/5, 1600/5, 2000/5, 2500/5, 3000/5, 4000/5 and 5000/5.

If the transformer ratio is not that of the transformer installed, the AFQ will not work properly.

AFQ-4W, AFQ-3W


Configure the number of current transformers, CTs NUMBER: - The AFQ-4W only allows the 3 current transformers (CT) option. - The AFQ-3W allows the configuration of 2 or 3 current transformers (CT).

In the 2 CTs option you must install TC1 measuring the L1 phase and TC2 measuring the L2 phase. The L3 phase is left without a current measurement transformer.

In three-phase mains with neutral, 3 CTs are needed to ensure the proper operation of the unit.

Configure the location of the transformers, CTs LOCATION. Select the load side option for CTs installed downstream from the AFQ, or the main side for CTs installed upstream from the AFQ. (See 3.5.1. CONNECTION OF THE AFQ-4W MODELS and 3.5.2. CONNECTION OF THE AFQ-3W MODELS). 3.8.1.2.- PARALLEL MODULE CONFIGURATION Access the parameter configuration screen by pressing CONF and select the PARAMETERS option.

Figure 29: Parallel module configuration.

Configure the number of units in parallel in the PARALLEL MODULES parameter (Figure 29: Parallel module configuration.). If there is a single unit in parallel, leave the default value (1). 3.8.1.3.- WORK MODE CONFIGURATION In order to configure the work mode, return to the home screen, press START and access the work mode configuration screen.

AFQ-4W, AFQ-3W


Start the harmonic filtering, phase balancing (1) and/or power factor correction functions depending on the needs of the installation (Figure 30). (For further information on all of the functions, refer to section 4.3.- CONFIGURATION )

Figure 30: Configuration of the AFQ-4W and AFQ-3W functions.

An incorrect configuration may significantly affect the performance of the AFQ. Consult the technician or qualified personnel to select the unit configuration, depending on the needs of the installation.

(1)The phase balancing option in AFQ-3W models works in unbalances produced by loads connected between phases in three-phase mains without neutral. The AFQ-3W does not compensate unbalances produced by single-phase loads connected between phase and neutral.

3.8.2- UNIT VERIFICATION

3.8.2.1.- VERIFICATION OF THE MAIN VOLTAGE AND FREQUENCY The voltage and current screen (Figure 31) can be accessed from the home screen by pressing on VIEW:

AFQ-4W, AFQ-3W


Figure 31: Verify main voltages, currents and frequency.

Make sure the main voltage measurements correspond to the real

voltages of the installation. Make sure the frequency measured by the AFQ is the real frequency of

the installation. Make sure the load current measurements correspond to the installation

current levels. 3.8.2.2.- VERIFICATION OF THE ACTIVE AND REACTIVE POWER The load power screen (Figure 32) can be accessed from the home screen by pressing VIEW:

Figure 32: Verify active and reactive power and load power factor readings.

Make sure the active power measurement of the load equals the power

levels of the installation. Make sure the reactive power measurement of the main equals the

AFQ-4W, AFQ-3W


reactive power levels of the installation. Check the cosΦ in the three phases. If there are phases with very high

reactive power and very low active power levels, this might indicate an error in the phase order. In this case, check the connections of the three-phase main power supply cables with neutral and the load current reading cables, as described in sections 3.5.1 and 3.5.2.

3.8.3- ACTIVE FILTER START-UP

Having checked the active and reactive power and power factor of the installation, you can return to the main screen to start up the AFQ. If there is no problem with the connections, the home screen should show the message “STOP” (Figure 33).

Figure 33: Message displayed when the unit is ready for start-up.

By pressing START, the active filter will take action to neutralise the harmonics, balance the phases and/or perform the power factor correction. If it has started up correctly, the screen will show the message “RUN” (Figure 34).

Figure 34: Message displayed when the unit is running.

AFQ-4W, AFQ-3W


If there is any problem in the connections of the filter or in the configuration, the “NOT INITIAL CONDITIONS” message will be shown along with a description of the malfunction (Figure 35).

Figure 35: Message displayed when the unit is not ready for start-up.

The APPENDIX A: DISPLAY MESSAGES of this manual contains all of the causes of malfunction and their corrective measures. If an alarm is tripped, the “ALARM” message will be shown along with a description of the problem (Figure 36).

Figure 36: Message displayed when the unit is in an alarm state.

4. OPERATION

4.1.- OPERATING PRINCIPLE

4.1.1.- HARMONICS

Non-linear loads such as: rectifiers, inverters, speed drives, ovens, etc., absorb periodic non sine-wave currents from the main. These currents are composed of a fundamental frequency component, rated at 50 or 60 Hz, plus a series of overlapping currents, with frequencies that are multiples of the fundamental frequency; they are defined as HARMONICS.

Figure 37: Distorted wave shape decomposition.

The result is a deformation of the current and, as a result, of the voltage, causing a series of associated side effects. These can be machinery overload, electric cable heating, circuit breaker disconnection, damage to sensitive units, etc.

Order (n) Mains frequency

Fundamental: 50 Hz Fundamental: 60 Hz 3 150 Hz 180 Hz 5 250 Hz 300 Hz 7 350 Hz 420 Hz

Table 5: Frequency of each harmonic.

4.1.2.- BASIC CONCEPTS

It is best to define some terms related to harmonics, fundamental for interpreting any measurement and study:

Fundamental frequency (f1): Original wave frequency (50/60 Hz).

Order of a harmonic (n): A whole number given by the ratio between the frequency of a harmonic and the fundamental frequency. The order determines the frequency of the harmonic (E.g.: 5th harmonic → 5•50 Hz = 250 Hz).

Fundamental component (U1 o I1): A sine wave component of order 1 of the Fourier frequency serial development equal to the original periodic wave.

AFQ-4W, AFQ-3W


Harmonic component (Un o In): A sine wave component of order over 1 of the Fourier frequency serial development a whole multiple of the original frequency.

Individual distortion rate (Un% o In%): A ratio in % between the RMS value of the voltage or harmonic current (Un o In) and the RMS value of the fundamental component (U1 o I1).

Equation 3: Individual distortion rate

True root mean square value (TRMS): The square root of the sum of the squares of all components forming the wave.

Equation 4: True root mean square value

Harmonic content: The difference between the total voltage or current and the corresponding fundamental value.

Harmonic distortion rate (THD): The ratio between the RMS value of the harmonic content of the voltage and/or current and the value of the fundamental component.

Equation 5: Harmonic distortion rate.

AFQ-4W, AFQ-3W


4.1.3.- MOST COMMON HARMONICS

Table 6 lists the most common harmonic generator loads and the wave shape of the current they consume, as well as their harmonic spectrum.

Type of load Wave shape Harmonic spectrum THD(I) 6-pulse converters: - Speed drives - UPSs - Three-phase rectifiers - Converters for

electrolysis and baths

- Discharge lamps - Single-phase converters - Lighting lines - Computer lines - Sound and image units

Table 6: Most common harmonics.

4.1.4.- HARMONIC COMPENSATION

Active filters are units responsible for the compensation of harmonic currents. Compensation is achieved by injecting harmonic currents equal to those in the installation in counter phase. This means that upstream of the filter connection point, the signal shows virtually no harmonic distortion. (Figure 38).

Figure 38: General connection diagram of an active filter

AFQ-4W, AFQ-3W


4.1.5.- OPERATING PRINCIPLE

Active filters are based on the following principle:

IFILTER = IMAIN - ILOAD

Equation 6: Operating principle

In other words, they detect the difference between the required current sine wave (IMAIN) and the signal deformed by the harmonics (ILOAD). And they inject the difference between both waves (IFILTER). Figure 39 show the wave shapes of the currents injected by the active filters. These show the required wave, the existing deformed wave and the filter current (IFILTER).

Figure 39: Current in the load, in the filter and in the main.

AFQ-4W, AFQ-3W


4.2.- DISPLAY The active filter has a touch display with different screens used for display and configuration purposes.

4.2.1.- MAIN SCREEN

The main screen contains information regarding the filter status, the start and stop controls, the alarm rearm process and the accesses to the configuration and display variables.

Figure 60: Function selection screen.

Harmonic filtering: Current harmonic neutralisation. (This option is enabled by default.) Phase balancing(2): Balancing of the current between phases. (This option is not enabled by default.) (2)The phase balancing option in AFQ-3W models works in unbalances produced by loads connected between phases in three-phase mains without neutral. The AFQ-3W does not compensate unbalances produced by single-phase loads connected between phase and neutral.

AFQ-4W, AFQ-3W


Reactive compensation: Function to compensate the reactive energy or correct the displacement power factor (cosΦ). (This option is not enabled by default.) Function priority order: The AFQ allows the functions to be prioritised in the event of filter current saturation due to overload. When the “Function priority order” function is disabled, priority is given to the current harmonic filtering and reactive compensation and overload balancing are penalised. If Function priority order” is activated, priority is given to current balancing between phases and reactive current compensation, ahead of harmonic neutralisation. (This option is not enabled by default.)

(Refer to section 4.3.6) 4.3.2.2.- SELECTIVE FILTERING Select the harmonics to be filtered on this screen (Figure 61):

Figure 61 : Selective filtering screen.

AFQ-4W, AFQ-3W


If the unit is configured with the control 1 algorithm (Frequency mode ) (refer to section 4.3.3.- CONFIGURATION OF PARAMETERS , select the harmonics you wish to neutralise from the 3rd to the 25th. (3rd, 5th, 7th by default)

If the unit is configured with the control 2 algorithm (Temporary mode)

(refer to section 4.3.3.- CONFIGURATION OF PARAMETERS, you can: • Leave all harmonics unselected. The AFQ will automatically filter

all harmonics from the 3rd to the 50th. • Select the harmonics NOT to be filtered. The selected harmonics

will not be filtered. Note: Use this option only if recommended by your supplier.

Click on the Main key to open the home screen. Click on the Back key to return to the work mode screen. Click on the Lock/Unlock parameters key to lock or unlock the configuration parameters. (Refer to section 4.3.6) 4.3.2.3.- ENABLE ALARM This screen (Figure 62) allows us to control the different alarms:

Figure 62: Alarm activation screen.

Polarity alarm: With the polarity alarm enabled, the active filter detects the direction of the load measuring transformer current and if it detects inverse polarity (current towards the main) it returns to the initial conditions and restarts with the new conditions in measuring the current. In the case of regenerative loads temporarily injecting current into the main, the polarity alarm will be activated. With the polarity alarm disabled, the active filter DOES NOT automatically detect the direction of the current of the load measuring transformers. The

AFQ-4W, AFQ-3W


polarity of the measuring transformers is defined as indicated in Figure 23 and Figure 24. In case of regenerative loads injecting energy into the main, the active filter continues to perform harmonic filtering functions. Negative active power on the load power display screen indicates that the load is injecting energy into the main.

Disable the polarity alarm only in installations with loads temporarily injecting current into the main.

This option is enabled by default and it is recommended not to disable it.

Before starting the active filter with the polarity alarm disabled, check the connection and polarity of the load measuring transformers.

Low temperature Alarm: This alarm is activated to prevent the unit from starting when the temperature inside the active filter is below 0ºC or when there is a problem in the connections of the temperature probes.


Resonance Alarm: The resonance alarm protects the unit against possible resonating currents between the AFQ and the load. This alarm is tripped when the level of a harmonic in the load current rises considerably.


Before disabling the resonance alarm, it is essential to make sure there is no resonating current between the active filter and the load. Resonating currents can damage the active filter and other devices connected to the installation.

AFQ-4W, AFQ-3W


4.3.3.- CONFIGURATION OF PARAMETERS

This menu (Figure 63) contains the parameters that have to be configured during the installation of the active filter. To be modify these parameters, you have to unlock the password (refer to 4.3.6.- PASSWORD) and have the filter in “STOPPED” mode.

Figure 63: Parameter configuration screen.

Minimum current: The minimum load current to start the active filter. The AFQ will stop when the load current is below the entered value and will start when it is higher. Control algorithm: Control algorithm selection:

1, Frequency mode: Harmonic filtering based on the selection of the harmonics to be neutralised from the 3rd to the 25th. (Option enabled by default.)

2, Temporary mode: Harmonic filtering based on the total and instant neutralisation of the 3rd to 50th harmonics. When the temporary mode is active, the AFQ resets all the harmonics selected in “Selective filtering” (Section 4.3.2.2) to completely neutralise the harmonics.

The Temporary mode (2) is NOT selectable if the location of the current transformers on the main side is enabled.

AFQ-4W, AFQ-3W


Do not use the Temporary mode (2) if the supplier has not recommended this for their installation. This method can cause resonance in certain installations.

Power limit This parameter allows the maximum power of the active filter to be limited. The value is configured as a percentage with respect to the unit's nominal power. The minimum configurable value is 20%, and the maximum is 100%. 4.3.3.1.- Modules in parallel Access to the configuration screen of the number of active filters set out in parallel with the same load (Figure 64).

Figure 64: Parallel module configuration screen.

A maximum of 8 AFQ units can be installed in parallel, with different power ratings.

All of the AFQ must use the same load transformer. Refer to the section 3.6.- PARALLEL CONNECTION OF 2 TO 8 ACTIVE FILTERS to install more than one active filter in parallel.

CTs ratio: The ratio between the load transformer primary and secondary. The active filter admits the following transformation ratios: 5/5, 10/5, 15/5, , 25/5, 30/5, 40/5, 50/5, 60/5, 75/5, 100/5, 125/5, 150/5, 200/5, 250/5, 300/5, 400/5, 500/5, 600/5, 700/5, 750/5, 800/5, 1000/5, 1200/5, 1500/5, 1600/5, 2000/5, 2500/5, 3000/5, 4000/5 and 5000/5. CTs number: This option allows you to configure the number of current transformers (2 or 3) used to measure the load. The AFQ-4W only allows the 3 current transformers option. The AFQ-3W allows you to select 2 or 3 current transformers.

In the 2 CTs option you must install TC1 measuring the L1 phase and TC2 measuring the L2 phase. The L3 phase is left without a current measurement transformer.

In three-phase mains with neutral, 3 CTs are needed to ensure the proper operation of the unit.

CTs location: Select the load side option for CTs installed in the load current (downstream from the AFQ), or main side for CTs installed in the mains current (upstream from the AFQ). (See 3.5.1. CONNECTION OF THE AFQ-4W MODELS and 3.5.2. CONNECTION OF THE AFQ-3W MODELS).
