Fire Risks The machine is designed to dry goods with a high risk of fire. The risk of fire is due to overheating of the goods to be dried. The operator must also check every time the temperature of the product at the end of the drying cycle in order to avoid the risk of fire. If the goods are overheated the risk of fire hazard is very high. The goods can start to burn inside the material and get burning after a few hours. The operator must also check every time the product before stocking. In order to avoid risks of fire for the product and also the machine, it is essential that the loading of the bobbins holder is done loading always with same number of bobbins in order to maintain constant the thickness of the product loaded. Only product of the same type and only product properly centrifuged has to be loaded. The bobbins to be dried must be uniform in dimensions, weight, moisture and type of fibers. It is forbidden to process on the same batch bobbins with different fibers, moisture or dimensions, UNLEVELED QUANTITY OF MOISTURE AND WATER TO EXHAUST CAUSE FIRE RISKS. At each shift, the operator must take out the bobbins holder from the inside of the machine. The machine is equipped with an manual anti fire deviced. The activating lever of the valve is located on the front part of the machine in well visible and reachable position.

Also ensure that the power supply cannot be switched on accidentally. To avoid possible danger always disconnect power, discharge capacitors and then connect to earth circuits then earth circuits prior to touch them. 5) The following rules must be strictly observed: - KEEP AWAY FROM LIVE CIRCUITS Under no circumstances should any person be permitted to reach within, or in any manner gain access to any enclosure with the power supply line switches to the equipment closed. 6) DO NOT ADJUST OR SERVICE ALONE Under no circumstances should any person reach within a unit for the purpose of servicing or adjusting the equipment without the immediate presence or assistance of another person capable of control and rendering aid. 7) Maintenance people should be qualified and accustomed to dealing with high voltage equipment. - DO NO OPEN PANELS OR DOORS WITH THE MAIN SWITCH “ON” Under no circumstances should any panel or doors be removed without the main switch has been disconnected first. 8) FORBIDDEN AREAS WITH MAIN SWITCH ON: fig.1-1 1- DRYING CHAMBER 2- RADIO FREQUENCY GENERATOR 3- HIGH VOLTAGE TRANSFORMER 4- RECTIFIER BRIDGE 9) Some goods can burn after few hours after the drying so operator must very carefully check the goods after the drying 10) RF EMISSION: Under normal circumstances the RF dryer is protected against leakages of RF interferences. RF seals and contact area at the doors or metal shields must be in perfect condition. 11) The RF dryer contains components with any potentially lethal high voltage . Under normal circumstances, access to these components is possible only through the use of special keys. RF SYSTEMS S.r.l. denies any responsibility for fire due to overdying of the product without the control by the operator of the product at the outlet of the dryer 3.2 FURTHER SAFETY INSTRUCTIONS FURTHER ZONES WHERE IT IS FORBIDDEN TO OPERATE WITH MAIN SWITCH ON 5- BOX WITH FAN 6- AIR HEATING ZONE Dangerous zones not for the presence of radio frequency but for the presence of other devices. 7- MOVING ZONE OF THE DOOR. Dangerous zone during the closing operation of the door. It is forbidden to stay inside this area while the operator is activating the closing system of access door to drying chamber. 3- GENERAL INFORMATION 11 3.3 GENERAL OUTLINES OF THE PROCESS The application of dielectric technology in the field of drying is worldwide known. We have many examples in glass industry, food processing, tobacco treatment, rubber manufacturing, textile industry. In general it can be said that whenever water evaporation with hot air systems leads to a less than satisfactory result in terms of quality of the operation and required time, dielectric technology is the right answer. The water molecule has a polar behavior and therefore it can follow the line of force of an electric field. In an alternate field, the molecule is made to follow the force lines of the field and during this movement it will interfere with other molecules of water that are present in the body to be dried out. During the process, molecules will collide continuously, thus increasing the overall energy level of the material; this explains why the temperature increases up to a point where the level of the internal energy will be high enough to allow the water to turn into steam. This technology acts on a selective basis meaning that heat development is proportional to the actual quantity of water. The absorbed power depends on the present quantity of water. Experience in textile industry In textile industry, radio frequency allows to dry natural and man made fibers in staple, hank, cone, package and top form normally immediately after hydro-extraction with good uniformity and better final handling. The generator works on a frequency of 27MHz and is stabilized and suppressed complete to suit international interference regulations with overload protection. Experience in the field of drying textile fibre by means of RF machines is growing rapidly. Applications Package and bobbins: After the removal of free water by hydro extraction these are dried with Radio frequency combined with forced air. RF energy is transformed inside each package in proportion to its moisture content.. Drying yarn packages by means of RFand forced air is the only means whereby the packages are heated uniformly , evenly and with low cost of drying. n The maximum moisture for the bobbins after centrifuge is: • • • • • - 45% wool - 18% acrylic, man made fibre - 35-40% mix acrylic-cotton - 50% cotton - 60% viscose Advantages • - the need for massive foundations and site preparations is completely eliminated and installation is easily and • • • • rapidly carried out. - flexibility : one set of equipment can dry packages, tops, hanks, loose stock and bagged products - productivity improvement - possibility to monitor costs accurately, often a difficult task with conventional drying - reduction of energy costs by 50-60% 12 3- GENERAL INFORMATION 3.4 GENERAL INFORMATION Description of the symbols used on this manual: PERSONS WITH PACE MAKER OR ELECTRONIC DEVICE CANNOT OPERATE THE MACHINE ATTENTION: indicates information about safety and precaution STOPPED MACHINE: indicates that operation must be done with machine “OFF” KEEP AWAY FROM LIVE CIRCUITS: indicates to disconnect electrical and pneumatic feeders OPERATOR: person experienced in charge of the machine with the only use of the panel control and of loading and unloading of the goods, person who checks the quality of the goods at the outlet MECHANICAL: person with mechanical knowledge who can run the machine and operate on mechanical parts.

Since the room is frequently obtained above roof level, its temperature in summer is often higher than the outside air temperature, which is generally measured in the shade. The max room temperature of 30°C must under no circumstance be exceeded. If higher outside air temperatures are possible, either additional cooling must be provided for the inlet or the generator power must be reduced in accordance with the following: INLET AIR 20°C 22°C 25°C 30°C REDUCTION OF POWER 100% (65KW) 90% 80% 60% Please take note that even continue operating in these conditions is guaranteed we suggest, in order to have longer use of the components, to maintain ambient temperature no more than 30°C. Measures must be taken to prevent air from entering the generator via the exit air duct while the unit is OFF. It is necessary to operate the machine with only the cooling fans running for about 30 minutes prior to startup the radio frequency. 3.7 INFORMATIONS FOR DEFINITIVE OUT OF ORDER AND DEMOLITION OF THE MACHINE If the machine has to be definitively dismantled , this operation must be done accordingly with local laws regarding the issuing of wastes and following CEE instructions CEE 75/442 regarding issuing of generic wastes for ambient protection CEE 78/319 regarding issuing of toxical and noxious wastes CEE 75/439 regarding issuing of used oils RF SYSTEMS is always available for advice or assistance in the event of difficulty being experienced in the operation and/or maintenance of the equipment. 14 3- GENERAL INFORMATION 4 DESCRIPTION OF THE MACHINE AND TECHNICAL FEATURES 4.1 TECHNICAL FEATURES FOR RKB70A SUPPLY SUPPLY VOLTAGE THREE PHASES 380 V - 50 HZ.

(Machine description) fig.2 4- TECHNICAL FEATURES 17 The radio frequency dryer type RKB70 is made up of one unit of 70 kW water cooled and is composed of the following components: n°1 drying gallery complete with electrode systems n°1 power electrical box 1 n°1 high frequency generator 70kW air cooled n°2 trolleys for loading and unloading the material DRYING GALLERY The drying gallery is made of the following components: Supporting frame : Equipped with upper footpath to get accessibility to the generator and air fans fitted on the top of the drying gallery. The lower part of the supporting frame is closed with panels. Box : This is a very rigid structure made of aluminium alloy plate; on each side inspection panels are provided. At each end of the gallery, frequency traps ensure total absence of RF radiation escaping out of the gallery. The grounded electrode is the gallery bottom plate, whereas the positive electrode is made of a longitudinal element which can be moved upward and downward so as to adjust the intensity of the electromagnetic field into the material. 1A Electrodes system : The upper electrode is basically made of an aluminium alloy frame plate or alluminium roller. The electrode is matched in order to provide a given profile of voltage versus the overall length of the electrode. The grounded electrode, made by the carrier of the bobbins, is the lower part of the dryng gallery and is made of a perforated plate for blowing the hot air (60°-100°C) trough the packages. The cycle time and temperature of air are controlled by the PLC. Air ventilation and exhaust system : The hot air is heated by a electrical resistors battery (24 Kw) and is propelled through the carrier (grounded electrode) and blown towards the packages. The moisture is exausted outside via an air fan. Power transmission line: Transmission RF lines are arranged with coaxial cables. 18 4- TECHNICAL FEATURES 2 HIGH FREQUENCY GENERATOR Oscillator : The high frequency generator is made of an oscillator and an electronic tube (triode). The oscillator has an L-C type of oscillating circuit (cavity type) driven by an electronic tube. This cavity type circuit ensures a very high overall efficiency, together with a remarkable stability of the working frequency with no electromagnetic interfering due to harmonic waves. Electronic tube : The second component which qualifies the high frequency generator is the electronic tube: this is of metal-ceramic type, air cooled. It is normally equipped with overload devices. Air module: The hot temperature air which goes through the circuit is propelled via ducting system back to the drying gallery in order to assist the heating process, to maintain a high dew point value and improve the overall efficiency of the dryer. the generator is electrically connected to the drying gallery by an induction systems; the tuning between the generator and the load is normally set at the commissioning and adjusted on the basis of the indications given by the customer. 3 MAIN SWITCHBOARD This is normally equipped with a blower for component cooling down and heat removal. It includes: - High voltage transformer : With dry isolation and its own overload protection. Two secondary taps will permit the accurate setting of the volatage on installation at the final site - Rectifier : Three-phase full wave type, it is made of 6 bars of avalanche diodes sets. 4 POWER AND CONTROL CIRCUITS : This part of the circuitry drives and controls: • position of electrodes • power transferred to the load • grid current • anode and grid dissipation • air cooling flow and temperature • start up sequence All components are sized for a continuous service operation; their quality meets a high reliability standard 5 LATERAL SIDES SUPPORT FOR BOBBINS HOLDER PLATFORM 6 TROLLEY FOR THE LOADING OF THE BOBBINS HOLDER PLATFORM 7 BOBBINS HOLDER PLATFORM 8 ACCESS DOOR TO THE DRYING CHAMBER 4- TECHNICAL FEATURES 19 9 REMOTE CONTROL PANEL located in the inlet set it consists of : • PLC The machine is equipped with SIEMENS S7-300 fully automatic touch screen PLC.

It is forbidden to open the control panel with the machine with MAIN SWITCH ON 5 GENERATOR OF RADIO FREQUENCY AND VARIABLE CAPACITOR: DANGER OF DEATH: risk of electrical shock: it is forbidden to open the removable cover with the MAIN SWITCH ON. Keep in mind that the removable covers are not electrically locked and inside the generator there is high voltage 10000 VDC 6 METALLIC PARTS: The machine is not equipped with metal detector. It is forbidden to operate goods with metallic parts, the high voltage of the electrode can make arcing and generate fire of the goods. 7 THE LIVE ELECTRODE, RISK OF DEAD: whit the RF on has high voltage which, if brought in to contact with skin, may cause dead. Never touch live electrode with had, tools or any objects such as bars. Never reach forbidden area with the radio frequency on operation. 8 WORKING ZONES : PRESENCE OF ELECTRO MAGNETIC FIELD : When the generator is on, even if the value of electro magnetic field is lower than security values, there is an electro magnetic field in working position and around the machine. Persons with pace maker are not allowed to use the machine. Also, the operator must take away eventual persons with pace maker who could be near the machine. The operators have to stay near and around the machine only for the strict time needed and have to survey the correct operating of the machine only at a distance of more than 2 meters. 9 DANGER OF FIRE DUE TO OVERHEATING: in order to avoid dangers of fire for the product and the machine it is mandatory to do the loading of the bobbins holder loading each time at full load in order to have constant thickness of the product loaded. It is mandatory to load at each time same type of product and only product previously centrifugated. Ths bobins must be uniform in size, weight and moisture. UNLEVELED MOISTURE AND QUANTITY OF WATER TO REMOVE ORIGIN DANGERS OF FIRE. The operator must check the drying level when unloading the dried product and eventually modify the set working parameters. Every time the dryer is turn OFF and at the end of the cycle, it is necessary to discharge the dryer in order to avoid the risk of fire due to overheating. Please take note that the goods can burn after many hours and the operator have to check that the product is not to hot at the exit many hours . Normally on an RF dryer if the product if over heated can burn from the inside after many hours so the operator cannot see the risk of fire . The only way to avoid any fire is to check at the exit that the product is not too hot and there is no bad smell. THE OPERATOR MUST ALSO CHECK EVERY TIME THE TEMPERATURE OF THE PRODUCT AT THE END OF THE DRYING CYCLE, AND CHECK THE PRODUCT BEFORE STOCKING. 10 DANGER OF FIRE DUE TO ARCS : fire may be generated from arcs between the bobbins holder and the brass contacts inside the drying chamber. These arcs are due to unproper positionning of the bobbins holder inside the drying chamber. When the operator takes out the bobbins holder from drying chamber he has to control visually the presence of eventual arcs or burnings and, if necessary, ask to a maintenance’s technician to intervene before to continue to operate with the machine. In case that arcs occur frequently contact RF SYSTEMS who will give detailed intructions for the execution of an extraordinary maintenance for the brass contacts and the supports of the bobbins holders. 11 FIXED ALLUMINIUM PANELS ON THE DRYING GALLERY: Risk of arcking . The doors must be look carefully in order to avoid an arcking between the frame and the door.
