Dear Customer,

The MASTERSONIC program represents a brand new approach in Sonic and Ultra-sonic power supplies and equipment.

The MASTERSONIC power supply equipment is based on MMM Technology, whichproduces high efficiency active power in wide-band sonic and ultrasonic vibrations.Wide-band sonic and ultrasonic energy (ranging in frequency from infrasonic up to theMHz domain) propagates through arbitrary shaped solid structures, heavy and very-thick-walls metal containers, pressurized reservoirs, very thick metal walls of autoclaves, etc. inmany different mechanical structures and in liquids, such as ultrasonic cleaning systems.The secret to its application is a novel sonic / ultrasonic, multifrequency power supply(MMM Technology) that can initiate ringing and relaxing, modulated, multimode mechani-cal oscillations including harmonics and sub-harmonics. The system offers fine controland excellent repeatability from its programmable interface and produces high efficiencyactive power ranging from below 100 W up to many kW.

Multifrequency, Multimode, Modulated Sonic & Ultrasonic Vibrations (MMM Technology)can be excited in any heavy-duty conditions, producing pulse-repetitive, phase, frequencyand amplitude-modulated bulk-wave-excitation covering and sweeping an extremely widefrequency band. Such sonic and ultrasonic driving creates uniform and homogenousdistribution of acoustical activity on a surface and inside of the vibrating system, whileavoiding the creation of stationary and standing waves, so that the whole vibrating systemis fully agitated. Such multifrequency ultrasonic structural excitation is ideal for agitatingarbitrary shaped liquid and solid masses at arbitrary distances and placed in open orpressurized vessels, containers, autoclaves, reservoirs and pipes, at any temperature,while maintaining optimum efficiency of electrical to acoustic energy transfer.

The oscillations of here-described sonic and ultrasonic source are not random - ratherthey follow a consistent pulse-repetitive pattern, being in the same time frequency, phaseand amplitude-modulated by the control system. This avoids the creation of stationary orstanding waves (typically produced by traditional ultrasonic systems operating at a singlefrequency) that generate regions of high and low acoustic activity. MMM technologyprovides great freedom of control, regulation and programming over all vibration, frequencyand power parameters.

Fields of possible applications related to MMM Technology are: Advanced UltrasonicCleaning, Material Processing, Sonochemistry, Liquid Metals and Plastics treatment,Casting, Molding, Injection, Ultrasonically assisted sintering, Liquids Atomization, LiquidsMixing and Homogenization, Materials Testing, Accelerated Aging and Stress Release,Plastic and Metals Welding, etc.

In traditional ultrasonics technology, transducers have been designed to satisfy preciseresonant conditions: In order to achieve maximal efficiency, all oscillating elements shouldoperate on the same frequency. MMM technology can drive with high efficiency anycomplex mechanical system up to a mass of several tonnes, consisting of arbitrary reso-nating elements. MMM technology, instead of optimizing transducers to accept certainresonant frequency operation, optimizes the complex electrical driving (or signal shape) tobe applicable to any specific oscillating structure, in a wide-band frequency domain,allowing mechanical designers to optimize their mechanical structures without limits.

1. INTRODUCTION

1.3. System safety:

Read this manual thoroughly and follow all directions and instructions toassure maximum safety during operation.

Installation of the MasterSonic (generator/power supply) and associated transducers,the “MasterSonic System”, is to be performed by qualified technical personnel only.

The MasterSonic System is an electro-mechanical device that under certain circum-stances could present an electrical shock hazard to the operator.

The MasterSonic System should only be used and operated by properly trained andqualified technicians.

Qualified technicians licensed by the manufacturer should only perform servicing ofthe MasterSonic System.

Use of controls or adjustments or performance of procedures other than those speci-fied herein may result in hazardous exposure to ultrasonic energy.

To avoid electric shock, do not remove the case covers from the MasterSonic System.There are no user-serviceable parts inside any of these devices.

Connecting the Generator unit to mains that supplies improper voltage may cause theGenerator to malfunction or create a shock or fire hazard.

Proper system grounding cannot be insured unless unit is connected to properly wiredthree prong 220 - 230 VAC single-phase outlet with a sufficient current rating.

Do not remove the grounding prong on the line cord plug.

The Generator Electrical Supply cord should not be plugged into a device (e.g. “powerstrips”, “gang plugs”, etc.) other than an industrial grade wall socket. Such other usecould cause significant changes in voltage that could result in an electrical fault indica-tion. This condition may occur even though other equipment plugged into multi-outletsockets continues to operate.

Do not restrict airflow to the MasterSonic System by covering or enclosing in a sealedhousing while in operation. Airflow must circulate through the unit during operation tofacilitate proper cooling of electronic components.

Do not place Generator on towel, foam or other soft surface since the material mayblock air vents. Blocking vents may cause Generator to overheat and malfunction orcreate a shock hazard.

Do not expose or immerse the MasterSonic System or the transducer in water orliquids. The system is not sealed against liquids and exposure may result in damage tothe equipment, create a shock hazard, or fire hazard.

Due to the general operating principles of the MasterSonic System and ultrasonics,this equipment is not suitable for use in environments where danger of explosion ex-ists.

The Generator should not be turned on until the Transducer Cable has been connectedto both the Generator and Transducer. Otherwise, damage to the Generator may re-sult.

When ultrasound output power is on, do not touch the transducer, booster, sonotrode,waveguide, or any device directly connected to these components; doing so may re-sult in injury.

Ear protection during operation of the system is highly recommended. Do not positionthe transducer, booster, sonotrode, waveguide, or any device directly connected tothese components near the technician or operators ears. The operating frequency ofthe MasterSonic System is below, within, and above the range of human hearing, andemits acoustic energy. Do not activate the system if system components are within 4feet (122 cm) of the ears of technician or operators.

2. SYSTEM SET-UP

2.1. Installation and connection.

MasterSonic open frame generator modules are designed for internal mounting in thecontrol cabinets of Ultrasonic Systems. Such cabinets should be very well ventilated,protecting the generator module from excessive dust, moisture, and harmful chemicalagents.

Before you mount your MSG.XXX.OF generators make sure that all protection conditionsare strictly observed and satisfied.

The installation and electrical connections of the generator should be performed by aspecialist in electronics who is already experienced in Power Ultrasonics.

Fig. 2.1. depicts the main power supply schematic and the Acoustic Load Connections forthe MSG.XXX.OF.

2.1.2. Acoustic Load Connection.

The acoustic load can be connected with two-wire or three-wire cable. For improvedsafety the manufacturer strongly recommends connecting the acoustic load using thethree wire connection method.

As show in figure 2.1 above the 2-Pin terminal connector in the lower right side of theMSG.XXX.OF terminals 15-HV (High Voltage and 16-LV (Low Voltage) are used to supplyultrasonic power to the Acoustic Load (piezoelectric transducer).

2.1.1. Mains Power Supply Connection

Using proper three-wire power supply cable, connect the MSG.XXX.OF to the mains powerline as follows:

L1 – Line is connected to terminal 11;Neutral is connected to terminal 12;Ground is connected to terminal 13.

Note: MSG.XXX.OF is designed as a component part for integration into Ultrasonic sys-tems. Therefore it is not equipped with a Power Supply ON/OFF switch. Make sure theUltrasonic System you are assembling is provided with such switch.

Terminal 15-HV is the high voltage ultrasonic signal output from the power transformerof the generator and should be connected to the Isolated Terminal of the transducer.

Terminal 16-LV should be connected to the inductive compensation of the transducerand to the acoustic system grounding (transducer housing or acoustic load mass).

Isolated Terminal (terminals between ceramic disks or rings without contact to front or back massof the converter) – This wire (normally Red / White / Black depending on supply source) is the HV (HighVoltage) terminal of the ultrasonic transducer.

Ground Terminal (terminals in contact with the front or back mass of the converter) – This wire(normally Green or Blue depending on supply source) is the LV (Low Voltage) terminal of the ultrasonictransducer.

Earth/Ground/Mass (normally Yellow / Green / Blue) – This wire is connected to the metal part ofthe Acoustic Load.

Connect the acoustic load to the MSG.XXX.OF as follows:

Connect the Isolated Terminal (normally Red Black or White) wire to terminal 15 - HV.

Connect the Ground Terminal (normally Green, Blue or Yellow) wire to terminal 16 - LV.

Connect the Earth/Ground/Mass (normally Yellow/Green/Blue) wire to terminal 14 - EARTH.

CAUTION: The MasterSonic System should only be operated with manufacture approvedtransducers and cable.

ATTENTION! Do not connect the High Voltage (pin. 15) to grounding. This will damage theSystem.

2 Wire Connections:If the acoustic load can only be connected with a two-wire cable, identify the wire that isconnected to the acoustic load’s ground (Low Voltage - LV) and the one connected to theisolated terminal (High Voltage - HV). Connect the wire that is connected to the acousticload’s ground/mass/housing to terminal 16-LV and the isolated terminal wire to terminal 15-HV. Connect terminal 16-LV and terminal 14-EARTH together. This will ground the acousticload internally.

Note: The manufacturer does not recommend this connection method and should only beused if a three wire connection is not possible. Two wire connections should only be madeby a qualified electrical technician.

3 Wire Connections: (PREFERRED METHOD)The preferred method for connecting MasterSonic generator power supplies to acousticloads is with a three-wire cable, as shown on the following schematic.

CAUTION: Be careful when handling the acoustic load transducers or cable. The acousticload may be charged with electro-static high voltage that may produce an electrical shockto the installer if not handled properly. Before installation or before connecting the acousticload to the Mastersonic generator carefully touch the High Voltage Black wire to the LowVoltage Blue wire to short circuit and discharge electro-static build-up.

CAUTION: Do not place Generator on towel, foam or other soft surface that may blockgenerator air vents. Blocking any vents may cause the Generator to overheat, malfunction,or create a shock hazard.

CAUTION: Connecting the Generator unit to mains which supplies improper voltage maycause the Generator to malfunction or create a shock or fire hazard.

CAUTION: The Generator should not be turned on until the Transducer Cable has beenconnected to both the Generator and Transducer. Otherwise, damage to the Generator mayresult.

CAUTION: The Generator Electrical Supply cord should not be plugged into a device (e.g.“power strips”, “gang plugs”, etc.) other than an industrial grade wall socket. Such other usecould cause significant changes in voltage that could result in an electrical fault indication.This condition may occur even though other equipment plugged into multi-outlet socketscontinues to operate.

CAUTION: Ensure all connections and mating surfaces are clean and dry before assem-bly.

Use the supplied studs to interconnect the mechanical components. All componentsshould be threaded by hand until snug, DO NOT force the threads, they must turn insmoothly all the way until the mating faces touch. Use two open end pin (spanner)wrenches and make final tightening.

As depicted in Figure 2.1.4. the Wave Guide or Booster should be connected to the trans-ducer tip. Acoustic loads (probes, sonotrodes, etc.) are connected to the opposite end ofthe waveguide or Booster.

2.1.5. Inductive compensation.

THE ULTRASONIC MODULAR GENERATORS MSG XXX.OF ARE DESIGNED TOSUPPLY POWER LOADS UP TO 1500W IN THE FREQUENCY RANGE OF 18KHZ ÷45KHZ.

Reduce the generator power to 50% or less when adjusting the inductivity and operatingfrequency first time, in order to avoid any over-load situation.

THE RESONANT FREQUENCY IS SELECTED DURING PARAMETER SETTING WITHTHE REMOTE CONTROL PANEL (CHAPTER 4.) THE INDUCTIVITY SHOULD THEN BESET WITH A HEXAGON WRENCH KEY INSERTED INTO THE TOP OF THE MSGXXX.OF WHERE IT IS LABLED (L). INDUCTIVITY IS CHANGED AS THE FERRITECORE IS OPENED OR CLOSED (core opening decreases the inductivity and vice versa).

THE INDUCTIVE COMPENSATION DEPENDS ON THE SYSTEM CENTER FRE-QUENCY, THE STATIC (shunt) CAPACITY OF TRANSDUCERS AND THEIR OPERATINGMODE.

The inductivity of compensating coil can be measured by an inductivity meter, placedbetween the LV terminal and a control feather to its right, as shown in the picture (when thegenerator is not connected to a main power supply: fully OFF). If we know the desiredcentral operating frequency of the transducer and its static capacitance, compensatinginductance can be calculated and set in advance.

2.2. Switching the generator ON.

After the generator is mounted in the cabinet, connected to the mains, and the Acoustic Loadis power supplied, it can be switched ON.

Make sure the power supply terminals are connected correctly. Also check if the controlblock terminals receive the correct signals.

The MasterSonic MSG.XXX.OF generator is delivered with short circuit external protections(terminals 1 and 2 are open) and with a 510 Ohm resistor connected between terminals 5and 6, which sets the power to 20% of the nominal output power.

If these two circuits are activated (terminals 1-2-shorten & 5-6 internally bridged with 510Ohm), you can test the operation of your MSG.XXX.OF. After connecting it to the mains youwill see its operation at low power.

Read carefully the following chapters to optimally adjust the generator for your application.The detailed explanation of adjusting the MSG.XXX.OF to the acoustic load will help youobtain excellent results from the generator’s operation.

2.3.1. External On/Off Power Control:

The external control of the generator is done through terminals on pins 1, 2, 3, 4 (fig. 2.3.1.).The way of connecting is shown on the drawing. Through pins 3, 4 the generator is switchedON or OFF. When the terminals are closed the generator is switched on and when theterminals are open, the generator is switched off.

NOTE: If the generator has been switched off because of activation of some internal block-ing or external protection the terminals remain closed. Next starting of the machine should bedone by opening and closing the terminals again.

NOTE: Terminals on pins 1 and 2 are protection inputs and they should be connected throughshort circuit enabling the generator to operate. If this circuit is open, the generator will stopoperating.

2.3.2. Analog Input Power Control:

The power of the generator can be controlled in the following three ways: The power can be set during the parameter setting of the generator. The power can be set through the RS 485 serial interface by the changing power

command of the Remote Control Panel or PLC. The power can be set through the analog input - terminals 5 and 6. When a 2.5 k-

Ohm potentiometer is connected to terminals 5and 6, as shown on picture 2.4., the power isset from 0 to 100%.

2.4. Control Block

The Control Block of the generator is built on a separate PCB, which also holds the controlterminals.The generator’s control is designed on several microprocessors and a Field program-mable logic. This ensures the generation of sonic and ultrasonic frequencies, according tothe assignment and the selection of feedbacks.Through appropriate selection of different generation/control modules from the micropro-cessor control and determination of the feedbacks and their influence over the system youcan achieve extraordinary results with your MSG.600.OF generator.Control Board Jumpers (J1 and J2 on fig. 2.5.) allow you to choose between two blocks formodulation of the acoustic load’s resonant frequency. By switching one or both types ofmodulation (called “Sweeping”= Math Sweeping and “Fast Sweeping”= DMMM) you canobtain different results in the acoustic load.Turning the two jumper blocks OFF turns your MSG.XXX.OF generator into a conventionalgenerator, operating on resonant frequency of the acoustic load.

The selection of Math Sweeping – modulation called “Sweeping” – generates forced MMMultrasonic oscillations in the acoustic load. The algorithm implemented in the microproces-sor, using the feedback from the Acoustic Load, calculates specifically modulated fre-quency output, which generates stable and forced MMM oscillations into the acoustic load.

Using the DMMM Sweeping modulation block (“Fast Sweeping”) you will always obtain excel-lent results, because this block is able exciting Acoustic Load of any size and shape in manyof its resonant modes, at the same time. The optimally selected feedback from the acousticload (specifically transformed with MMM signal processing block) will initiate real-time, Dy-namic change of MMM oscillations, tracking the time-evolving load properties in a wide-bandand multifrequency regime of oscillations. This will generate completely homogenous 3Dultrasonic activity in an ultrasonic cleaner. This is the reason to call this block DMMM.

The optimal selection of feedback-parameters (Jumpers J1 and J2) is very important forgeneration of homogenously distributed, 3D ultrasonic activity field. Many tests of theMSG.XXX.OF generators operating with different ultrasonic transducers and loads are showingthat the acoustic load’s feedback-phase (positive and negative leading edge of DMMM) isalso very important for the proper operation of DMMM Sweeping.

Consequently, the most precise method for obtaining homogenous 3D ultrasonic activity inmechanically different acoustic loads is the Heuristic method.

Fig.2.5. and Table 2.5. show the position of J1 and J2 and the adjustment of differentoperating modes of MSG.XXX.OF ultrasonic generator.

2.7. MSG.600.OF Generator Parameters:

For mastering correct adjustments of your MSG.XXX.OF generator and obtaining excellentresults from its operation you should be very familiar with all its resources.

The correct adjustment is done through MasterSonic Remote Control Panel MSH-1 orMSA2218 Adapter for PC/PLC with the particularly developed MasterSonic software.

The following generator parameters can be set and adjusted:

The operation with the Remote Control Panel or the MasterSonic software through theMSA2218 Adapter is described in the following chapters.

The yellow indicator lignts on when the generator is connected to the mains.

3.2. Green Indicator light:

The green light is illuminated (on) when the generator is turned ON and producing ultrasonicpower output to the transducer. When the generator output power is turned OFF this light isnot illuminated.

3.3. Red ext. block Indicator light:

The right red indicator is connected to the generator protection circuits. If the generator isexperiencing an external problem or detecting a problem with the mechanical ultrasonic com-ponents it will automatically stop ultrasonic power generation. Then the red light is illumi-nated. The light will turn off at next start up of the generator.

3.4. Red overvoltage Indicator light:

The left red indicator light is on when the overvoltage protection is actuated. The light will turnoff at next start up of the generator.

3.5. Inductive compensation regulator.

The inductive compensation regulator controlls the inductivity by regulating the airgap ofthe ferrite core. Turning the regulator to “-” opens the airgap of the ferrite core and the inductivity de-creases. Turning the regulator to “+” closes the airgap of the ferrite core and the inductivity in-creases.

When the ferrite core is closed the inductivity is approx. 2mH When the Ferrite core is max. opened the inductivity is approx. 1mH.

ATTENTION: The inductivity is set to max. during transportation.

PARAMETERS SETTINGS OF MSG.600.OF - TUBULAR TRANSDUCER

First place the tubular transducer into a vessel with water. Tubular transducer should be fullyimmersed (do not operate it in air). Connect all cables. Connect the MSG generator to 220-230 VAC, main supply voltage. Then, use the handy keyboard (MSG generator programmingunit) and set all parameters for constant frequency operation (no sweeping, no modulation):

Sweeping: 0Fast sweeping 0Power: 50%PWM period: 0.010 sPWM ratio: 100%Frequency: 26.650 kHzTracking range 0

Start testing the system, starting with 26.650 kHz (central operating frequency, or frequencycarrier) by increasing it slowly. The best operating regime will be found close to 28.000 kHz(or on a little bit lower frequency). The second relatively well operating regime will be found inthe carrier frequency area between 30.000 kHz and 33.500 kHz. The best results will befound later at 28 kHz and 33 kHz carrier frequencies.

Now, start introducing frequency and time modulating parameters, using the handy program-ming unit (gradually increasing or decreasing above given values). Make new settings, as forinstance (very good operating regime):

Sweeping: 2Fast sweeping 50Power: 100%PWM period: 0.100 sPWM ratio: 100%Frequency: 28.280 kHzTracking range 10

Test parameters variations around above given values (applying the values given below),using very thin aluminum (kitchen) foil, to see when the fastest foil perforation (in water) isachieved (take the thinnest foil you can find).

Sweeping: Try from 30 until 150 (very good 60 until 80)Fast sweeping: Try from 1 until 5 (very good 2 until 4)Power: From 0 to 100%PWM period: Try from 0.020 s until 0.200 s (good from 0.05 until 0.1)PWM ratio: Try from 50% until 95% (very good 100%)Frequency: Try from 27.000 until 33.000 kHz (very good 28 and 33 kHz)Tracking range: Try from 5 until 20 (very good 7 until 15)

If MSG generator suddenly stops, this would mean that you made certain parameter setting/s that is out of the operating range (out of the safe operating margin). Just change theparameter in question, or reduce the power, and restart the MSG generator.

Memorize the best set/s of parameters (there are 10 available memories for memorizingdifferent sets of parameters).
